Sweet Melissa
And no one knows the gypsy's name
No one hears his lonely sigh,
There are no blankets where he lies.
In all his deepest dreams the gypsy flies
With sweet melissa...
-- Allman Brothers Band
In the first semester of my sophomore year at RPI, my living arrangements broke down completely and I moved into a big house with a lot of other guys on Hoosick St., where I passed the second semester in the bright haze of the Student Revolt that thrashed the U.S. college scene in the spring of 1970, after it became clear that Nixon's secret plan to end the war in Vietnam included a lot of war in Laos and Cambodia. There was also the Kent State thing and everything everywhere went kerflewy for a while, even in so conservative a place as RPI.
By the end of my sophomore year, I decided that living off-campus wasn't really that grand, and besides, I had a lot of on-campus responsibilities, plus, no automobile. So I went to the campus housing office and put my name in. The mad rush for the best housing had already subsided and all the better quarters were supposedly gone. But RPI had a policy of housing any student who asked, so I was sure to have a place to live. It was just a crapshoot as to how bad it would be.
That summer, my folks moved to Illinois from Nashville, and I helped them move. I made some halfhearted attempts to get a summer job, but non-farm jobs in southern Illinois are not thick on the ground, and I had no farming experience to speak of. So that was the one summer in my high school and college years when I just basically loafed.
I returned to RPI to discover the damnedest thing: for years, all RPI co-eds were housed at Burdett Avenue Residence Hall. BARH also held a fair number of male students, the fraction of RPI students who were female being that small. Also, for years, the freshmen co-eds complained of the arrangement. All other RPI freshmen were down in the Freshman Dorms, strange brick-and-cinderblock buildings with names like Nason Hall, Crockett Hall, and (the one I'd been in) Hall Hall. The freshmen women felt left out of ordinary freshmen living, disconnected from their incoming class, as it were.
So in 1970, the powers-that-were decided to do something about it, and that "something" was to make some additional renovations to one of the freshmen dorms, Warren Hall, to be specific, and use it to house the freshmen co-eds. Actually, again owing to the small number of freshmen women (I believe there were about 80), it was only the top two floors of Warren that housed the freshmen co-eds. The bottom floor held the lounge and about 60 upper class men and women.
One of those 60 was me. Go figure. I'd won some sort of strange lottery. The rooms were doubles, and each had its own bathroom, which put it way ahead of the rest of the freshmen dorms, which had communal bathrooms at the end of the halls. There's nothing like waiting for a shower on a cold morning, or finding all the toilet stalls occupied.
Warren Hall was also about 200 yards away from the Student Union, where I was to spend most of my time that year. Going into my junior year, I was still nominally the editor of Perspective, ostensibly a magazine of politics and philosophy. But I'd managed to put out two issues, not quite single-handedly, and there was never to be another. I might have turned it over to some of the New Left type guys who were kicking around, but I didn't get along with them in those days. (We're happy to spend time together at reunions, nowadays, but I can't say who has changed more, me or them. It's probably irrelevant at this distance).
In any case, I was also managing editor of the Rensselaer Engineer, which had a better budget, an actual staff, and better cachet with the professors and such. I wound up spending a lot of time that year on Engineer activities.
Early in the semester was "Activity Day," or some such, where all the student activities that had any connection to the Student Union (i.e. practically all of them, since the SU doled out money) set up a table in the Union and begged, er, asked the new freshmen to join up. I was working a small table for Perspective, but also lending John Benson, the Engineer's editor a hand, since there was (let's face it) more interest there.
I remember practically nothing of the entire afternoon except the moment when Melissa walked in.
She had, I learned later, recently given up on trying to straighten her hair, straight hair being the fashion at that time. I think the idea was to look like Joni Mitchell, which is a really great idea for Joni Mitchell, but not so good an idea if your hair is naturally curly. Melissa's was not quite Afro curly, but it did not take to the idea of straightening, and on that day, it was a halo around her head.
Also, the day was one of those bright, overcast days, where there are no shadows, but the light can nevertheless be enough to make you squint. But Melissa did not squint as she came into the room; her eyes did go a little wider, however, and the light from behind us caught them and the blue of them gave me that pressure in the forehead that says, "Okay, you got me. I'm hooked. Just reel me in and fry me up."
There were only maybe two or three other women in the freshman class who were in the running for "best babe," or whatever phrase one uses to try to cover the aching need that wells up within us when confronted by that which we desire. Melissa was the most striking of the lot. And, as you may have already noticed, she lived in my dorm.
One night, I visited her in her room and. we violated the dorm rules by my staying past the time when visitors were supposed to leave. By several hours. We left the lights off, and eventually we had to put a towel to block the light that seeped in under the door, because our eyes had become so dark-adjusted that the slit of light hurt our eyes. We mostly talked, in that time-honored tradition of young about-to-be-lovers, and even at this distance I am reluctant to reveal any of the things she told me. I have no idea what I told her, other than that I'm sure it was equally personal, equally precious, and equally unimportant to anyone other than ourselves.
Likewise, the other details of the "us" that existed for a while are not that interesting to outsiders, at least that would be my guess. But there are some lessons to be learned from the ending of it.
I don't think that much of it was my fault, though I am predisposed to grab all the blame I can manage. Essentially, Melissa could not take being at RPI. The workload was a factor, I would imagine, but not that great of a factor. No, the real problem was that Melissa was simply not able to handle being the object of everyone's desire.
Consider. If a girl is somewhat pretty, or even beautiful, in ordinary circumstances, well, there are still others who occupy that ground. In a high school of, say, 3000 students, the top 2% of the girls, (by whatever measure of attractiveness you care to use), still number around 30. Moreover, there are still plenty of other girls around, so the boys aren't all vying for the affections of just those 30.
But at RPI, the top 2% of freshmen coeds in 1970 calculates to 1.6. And there were 1000 male freshmen, and four times that number of other male students. In a random lottery, the odds that Melissa would fall for me would have made drawing to an inside straight look like a sure thing. So I was exceptional. Okay, fine. But she was even more so.
Simply having "a guy" was not nearly enough. Of the thousands of other students at RPI at that time, how many were so socially dysfunctional that they would pester the most attractive woman around, despite who else she might be seeing? Maybe if I'd been the jealous sort, always around, always snarling at any other male who looked at her, then maybe Melissa's phone would not have rung two or three times an hour with some guy at the other end asking her out. Some guy she'd never met or barely remembered. Maybe. But I was not that sort of boyfriend, and, frankly, if I had been, I don't think we'd have lasted as long as we did.
Eventually she could not take it any more. She saw the worst of male behavior on a regular basis. Regular? More like continuous. And she got so tired of it that she had to leave.
So she did. She left RPI, and she left me. She broke up with me first, explaining that she had to leave and that I was a major reason for staying, and, well, it's both flattering and distressing to be given that as a reason for a breakup. There were a few scenes between us before she left, and I accept full blame for those.
Then she was gone. I tried maintaining a correspondence, and that worked for a little while, and then it didn't. One thing about this writing thing is that it takes a while to get it under control. I suspect that had something to do with it. But, ultimately, who knows?
I think of her occasionally, and I have the heartfelt hope that she had a good life after she left RPI. She deserved the best. She deserved better than I was at the time, even, and you know how full of myself I can be.
I didn't have much of a social life for a while after Melissa left. That's the way it is with romantics. My next lover was the wife of a pretty good friend. That's the other way it is with romantics. We do so like to play it safe.

The Philosopher's Stone
My favorite lab work in the course was neutron activation analysis, which is very, very cool. After exposure to neutrons, many elements become radioactive, having at least one isotope that does so after neutron absorption. This is especially true of the heavier elements, which tend to have a lot of isotopes and a lot of energy shells in their nuclei. Most of the artificially created radioisotopes have a gamma spectrum associated with them, so if you measure their decay using a multichannel gamma spectrometer, you get a "fingerprint" of that isotope. Repeated measurements also give you decay rate information, and, putting all that together, you can usually get a pretty good quantitative trace element analysis of the original sample. Also, because only a few atoms absorb neutrons, and the product isotopes are usually fairly short lived, it's a non-destructive technique that can be repeated many times using the same sample.
The neutron source we used was called a "bomb" as I recall, not because it could explode, but because it was big and heavy and looked like laboratory "bombs" that contained compressed gas. What our N source contained was, if memory serves, beryllium and cobalt-60, the latter explaining the heaviness of the device. It was very thickly shielded.
Under high energy radiation, beryllium becomes a neutron source. Our source exploited the gamma-neutron reaction, which splits off a neutron from Be-9; the resulting Be-8 is unstable, and goes to two alpha particles. There is also an alpha-neutron reaction that gives a neutron and carbon-12. The early "initiators" on nuclear bombs used this reaction, with polonium as the alpha source, because it doesn't emit any gamma radiation, so it only worked after the Po and Be were brought close together, reducing the likelihood of pre-detonation.
Both boron-11 and deuterium also undergo the gamma-neutron reaction, though not as efficiently as beryllium. Californium-252 is also sometimes used these days as a neutron source, as it undergoes a fairly rapid rate of spontaneous fission.
There are commercial neutron sources that use nuclear fusion as the neutron source. Many of these are basically small particle accelerators that aim a beam of deuterons at a target that has tritium adsorbed onto it. A sufficient number of fusion events occur to make this a viable source of high energy neutrons for industrial applications. The D/T reaction has a characteristic energy (around 14 MEV), which is useful for deep imaging applications. Some of these type of neutron sources are quite small.
Larger installations often use full bore particle accelerators to create fusion, and sometimes the deuterium-deuterium reaction is used. This gives a lower energy to the resulting neutron, but deuterium is much cheaper and easier to work with than tritium, tritium being both radioactive and a proliferation hazard.
Another interesting neutron source is the Farnsworth Fusor, or rather, its descendants. These are "inertial electrostatic confinement" fusion generators, and examples of them have even shown up in high school science fairs. Usually, the rate of fusion is quite low; I've seen numbers for quasi-amateur builds that produce maybe a million fusion events per second. The radiation hazard from attendant X-rays is greater than the neutron hazard. However, I've also seen some advanced laboratory results suggesting output as high as 10^14 events per second which is respectable and dangerous. Once you get to this level of output, radiation damage to the electrical components becomes important, an indication of just how difficult the fusion problem is, since you're still orders of magnitude from practical power production.
If you want a really high neutron flux, the usual method of production is a nuclear reactor. Reactor-based high energy neutrons are usually obtained in a reactor with a fast core but a moderated outer shell that achieves criticality, thereby sidestepping the safety issues that come into play with fast reactors. However, there are "pulsed" reactors that rely on changes in neutron cross section with temperature to create "inherently safe" designs. One such design was described by Freeman Dyson in his book Disturbing the Universe.
Reactors only produce "fission spectrum" neutrons, of course, although for fast reactors the spectrum is shifted toward higher energies. If you really want a big flux of high energy neutrons, failing some major breakthrough in fusion technology, you want a "spallation source."
Spallation is based on the fact that, if you hit a heavy nucleus with a very high energy proton, you get a neutron "splash" effect (this would be the "liquid drop" model of the nucleus, we're using here). The Spallation Neutron Source in Oak Ridge, Tennessee runs a high power (over a megawatt) proton beam at about 1 Gev (1000 Mev) and gets about 30 neutrons per proton in the beam. The neutron spectrum of the output peaks at around 10 Mev, but some of the neutrons have much higher energies.
The Oak Ridge facility uses mercury as the spallation target, with the indication that liquid targets are more robust to the sort of shocks that a pulsed accelerator beam produces. There were some designs from an old USSR program that used a eutectic mix of lead and bismuth for a similar purpose, heated to liquefy the metal.
Remember that I noted above that reactors are sometimes used as neutron sources. One reactor design is to use a "subcritical" fast reactor and drive it to power production via a spallation beam. If, for example, the criticality of the reactor is 0.95, meaning that it is only 95% of the way to self-sustaining, then any neutron introduced into the reactor core will induce a reacton chain of about 20 more neutrons. Thus, a spallation source plus a sub-critical fast reactor can be a copious source of fast neutrons. Moreover, it's overall power balance will be positive; it will generate considerably more power than it consumes.
I've noted before that fast neutrons are a modern equivalent of the "Philosopher's Stone," able to transmute elements, and able to convey, well, not eternal life, but eternal death to those exposed. It's the transmutation aspects that have caught some interest. Fast neutrons will fission all transuranic elements, so, properly run, there is no plutonium et al. remaining after an accelerator driven reactor fuel cycle has run its course. In fact, an accelerator-driven reactor system can be designed to run on nuclear waste remaining from other reactors. It's also been suggested that other long-lived waste products, like technetium-99 and iodine-129 be transmuted to shorter-lived isotopes, taking the nuclear waste disposal problem from a time scale of millennia to a matter of years, or perhaps centuries if you don't want to transmute the cesium and strontium waste isotopes.
It sounds great, doesn't it? Nuclear energy without the waste disposal problem? So what's the catch?
Well, there are a couple of technical catches, such as the fact that even the Oak Ridge facility doesn't have the power to drive a full closed-cycle system. But that's a technical matter, and I have no doubt it's solvable. There's also the fact that such a system requires on-site fuel reprocessing, to extract the transuranics and other long-lived isotopes from the waste stream. That's a chemical engineering problem, and we don't have much experience with designing chemical processes that are totally closed cycle. More accurately, trying to do so has always resulted in some leakage, plus the occasional outright accident.
Still, it might be possible to get the thing to work well enough, technically speaking.
But there's a deeper problem, and that has to do with social and economic systems and ideology. As I've said before, nuclear energy is inherently "socialistic" in the sense that it requires government level planning and operation at every step of the way. Yes, an accelerator-driven nuclear power system would produce a substantial power surplus—at enormous initial capital cost. A government can pick up that tab and take that kind of risk; corporations could raise the money (the estimated price tag for a ADS is on the order of $20 billion, but would probably be notably higher, given NIMBY concerns, etc.) but are simply not trustworthy when it comes to high public risk endeavors. Corporations take risks to enhance profits. It is up to government to regulate corporations' risk taking, but the ascendance of Conservative Movement ideology in this country has degraded the regulatory process to such an extent that one simply can't trust the regulatory function of government. The NIMBY folks are not being mere obstructionists. They are being realistic.
It's said that there was a time, in the early days of explosives manufacturing in Europe, when the owners of an explosives company were required to live on site. Ask yourself how many corporate executives would situate themselves and their families next door to any nuclear reactor site.
ADS systems are well-suited for thorium fuel cycle nuclear power, and India has a lot of thorium, but not much uranium. And if China ever decides to curb its greenhouse gas emissions, ADS systems would look very attractive. Naturally socialistic, remember? Very much in the Chinese tradition. The two countries look like natural competitors in this particular game.
The U.S. does not. The oil and gas men are still in charge, willing to expend trillions for neo-colonial wars and the perpetuation of various sorts of privilege. The idea of spending government money on the creation of actual industrial capital is ultimately foreign to them. So here, as in so many other endeavors, the U.S. will not be on the cutting edge of technology. It is no longer up to the job.

Cheap Records
You don’t usually get the mega-hits in remainder bins, though the hits do show up in as used in stores devoted to that purpose (usually not at the cheapest prices, of course). Used vinyl was/is a risky purchase, since even apparently clean albums sometimes have a single, major skip somewhere. CDs are more forgiving, but the downside of that is that more people treat them badly, so used CDs often have pretty ugly surfaces and sometimes those render one or more tracks unusable. Nevertheless, there are often some tricks that can recover the track for ripping if not for straight play. The same holds true for vinyl, there being some wonder-products that clean and even repair (to a very limited extent) the surfaces.
Buying closeout records is sometimes a bit ghoulish. When MGM records failed to option Frank Zappa in 1968, Zappa formed Bizarre Productions, and a good bit of Zappa’s MGM catalog went to remainder, including Lumpy Gravy, which I bought (and then lost to the aforementioned burglary). There must have been something going on with MGM records, because all of the “Boston Sound” artists hit the cheap bins at about the same time. A while later, MGM sold out to Polydor, and another big batch of product hit the remainder shelves, including a number of Verve recordings.
When Tetragrammaton Records bit the dust, I got some Bill Cosby records, plus Steve Barron and some others. The Phillips label also had some financial difficulties, so I own a couple of copies of the classic H. P. Lovecraft II album, and it’s near the top of my list for conversion to MP3.
Realize that buying cheap records doesn’t actually save you any money; you just buy more albums with the same budget, or lack thereof, which is to say, all your disposable income. After I moved to California, I joined a taping club for a while, not so much to save money on any given record, but because the effort involved in taping put a limit on the number of albums I could get at any given time so I saved in the aggregate. The net result of that is a cache of reel-to-reel tapes of some records that are almost impossible to get elsewhere like the Handscapes by the Piano Choir, or Across the Western Ocean by John Roberts and Tony Barrand.
Amy has been involved with a non-profit organization that runs a thrift store, and from time to time a big box of cassette tapes will come in and she’ll get it cheap. One of them was amazing; it had a lot of on-air recordings from KPFA in the mid to late 80s, especially one called “Do Wop Delights” featuring 50s do wop and gospel records (again, some of them so rare as to be unique). There have also been a lot of mix tapes from various people, some of them pretty good music programming (says the conceit of one who thinks he knows). Having those tapes makes the old tape deck in my car more attractive.
There isn’t a single thing that I’ve mentioned in this essay whose purchase put money into the pocket of the recording artist or any other copyright holder. The close-outs do profit the record labels, but that’s about it. Taping clubs pretty much died from threat of lawsuits, just as Napster etc. quit the field owing to legal actions. Neither the demise of Napster nor the end of taping clubs had any real impact on the fortunes of artists, nor would the elimination of libraries assist writers (quite the opposite, as there are some books and even entire small presses that sell mainly to libraries). There are, of course, writers and musicians who’d like to charge rent every time anyone reads or plays anything of their work.
For that matter, paying full price for records benefits a limited number of people. I once had a conversation with a bass player who had just made an album. He explained that the only money anyone in the band really made on the album was from the session fees. The songwriter gets some extra juice, but everything else is water and wind.
On my side of it, if somebody makes some money out of anything I write, I’d like a taste of it. Otherwise, get a bucket and have yourself some free words. It’s a complicated dance, the conspiracy between the author and the audience, and even guys who fill stadiums probably sometimes feel like they’re dancing alone.

Taking Out the Trash
Since my Mom didn’t get along real well with most of her family, when Dad died she sold the house and moved away, first to a small town in Tennessee, then later to Ohio, to be near my sister and her family. But that’s a tangent, and not what this essay is about.
Another tangent would be the fact that I could take the time to spend several months with my Mom and ailing Dad because, after my bout with the disease that we won’t call chronic fatigue syndrome, I’d set up my professional career around a series of research and consulting contracts that mostly did not require my on-site presence. In fact, most of what I was working on at the time was analysis of smog chamber data from the University of North Carolina, so I was actually closer to the main project when in Georgia than when in California. In any event, my physical presence was rarely required, so I could travel or not, whichever I desired, so long as I had a portable computer and email, etc. I took full advantage of this setup when I went-a-courtin’ Amy in New York some time later.
But the crux of what I’m getting to is that, during the few months I was there, I helped my folks evict some people from a house we owned.
The actual circumstances were a little complicated. Theoretically, the people in question, whom I shall call the Jukes, because it’s easier to spell than Kallikaks, owned the house, and we were foreclosing on a mortgage that my Dad had held. He certainly didn’t ask my advice about personally holding the note; I’d have told him to sell it the regular way and put the money into a mutual stock or bond fund. But Dad wasn’t thinking straight for the last couple of years of his life, owing to the massive amounts of serotonin that his carcinoid tumor syndrome was pumping into him, and he was trying to provide an income for my Mom after he was gone. And I’m pretty sure he knew that something wasn’t right, and he was feeling mortal. So he’d bought this old house, fixed it up nice, and sold it, with the idea that it would provide an income stream. This isn’t a totally stupid idea, and the Jukes looked like a good bet, at least on paper, family of four, father with a decent job with the county, etc.
The first time I ever met them, I knew they were trouble. But the deal had already been done, and that was before Dad was diagnosed, and who knew? Besides, dealing with people in real estate is always a crap shoot. I’d bought a house down there earlier, with the idea of my folks practicing their “property management skills” on it. Over the six or seven years I owned it, we had four tenants, two pretty much okay, one who did so much fixing up that I could raise the rent after they moved out (I was damn well not going to raise the rent while they were there; they were a landlord’s dream come true), and one that so trashed the place that I had to drop the rent back down again. I made some profit when I finally sold it, but not much, because real estate in South Georgia isn’t the money machine that exists in California or the Northeast.
But back to the Jukes. Papa Jukes had lost his job, and they were up to their eyeballs in credit card debt, so mortgage payments had stopped several months before I got there. So I drove my folks to and from the lawyer’s office, and to and from the courthouse, and did my little testifying when I had to, and “repurchased” the house in the foreclosure proceedings, because there was no way that anyone was going to pay what we were owed after the Jukes had been in the place. The “repurchasing” consisted of trading the debt that we were owed for the house; in other words, no money changed hands because we were just repossessing, but theoretically someone could have outbid us for it (yeah, right).
Then I went over and began to assess the damage and try to clean it up.
They’d used an old discarded toilet as “lawn sculpture” in the front yard, a little poke in the eye to their neighbors, not that I really cared that much about the finer sensibilities of the neighbors. But the pile of old, wet carpet out in the back didn’t sit well with me, because I remembered the work my folks had spent installing it in the first place. They’d also pretty much demolished the tool shed, and installed a dog pen that still reeked of dog and dog waste.
Once I got inside, I found that they’d replaced the wall to wall carpeting with “vinyl carpeting,” the stuff you usually find in kitchens and bathrooms. It was in the kitchen and bathroom, sure enough, but it was also in the living room, halls, and a couple of bedrooms.
Apparently, because it was called “vinyl carpeting,” they’d installed it with carpet tacks. This made the bathroom really interesting, because the water spilled in the floor had seeped through the tack holes to get under the carpeting, thereby rotting out the floor. After I removed the vinyl, I went over the bathroom floor, pounding it with a broom handle to test for rot. When I was done, there were maybe two boards left; the rest was just joists and air, and some of the joists were half rotted through.
Then I went out and pulled up the rest of the floor covering. I’d noticed that the damp carpet out back was stained, and reeked of dog crap and urine. I figured that they’d removed it and replaced it with the vinyl because the vinyl was easier to clean.
What I didn’t figure on was that they hadn’t bothered to clean the wooden floors underneath before they put down the new vinyl. Yes, you have that right. When I removed the floor covering there was dried dog urine and feces underneath.
I spent the next two days basically mopping floors, repeatedly. First I’d use bleach, then regular detergent, then ammonia, then more detergent, etc. (You'll notice that I never used bleach and ammonia back-to-back, as that is dangerous). I really don’t remember how many cycles it took before the stench subsided. I don’t even want to try to remember.
I told very little of this to my Dad, and I made sure he never went over to look at the place. He was due for surgery in a few weeks and he didn’t need to be bothered with that crap.

Thinking Outside the Box
The “three-dimensional” part of the name says that a volume was divided up into a lot of compartments, “grid cells” in the jargon, and the “Eulerian” part says that the grid didn’t move around, although there was a bit of cheating on that one in that the top of the modeling region rose with the “mixing layer” in some versions of the model. The alternative to “Eulerian” is “Lagrangian” where the model volume itself moves around, usually with the fluid flow, which is to say, the wind. That’s a “trajectory model” and it usually had only a single box, although we developed some multi-box trajectory models to handle plumes like those from power plants. A single line of boxes is “one-dimensional;” a “moving wall” of boxes is “two-dimensional.” A single box, therefore, is “zero-dimensional.”
So-called “box models” are common in air pollution, and other areas of environmental modeling. They can be really simple, especially if you are dealing with pollutants that don’t react. Then all you have to do is have a source input for emissions, a “ventilation rate” for the combination of wind and diffusion that’s removing material from your box, and boundary conditions for what kind of air is replacing what’s in the box. This is the sort of model that you get on first year chemistry or physics courses; it can be expressed in a single differential equation.
You can make the box pretty big, too, provided you’re willing to take these big honking averages of everything. For either non-reactive or “first-order” (those that just decay all by themselves, without reacting with other things) pollutants, your average result for the single box calculation is the same as if you’d done the multi-box calculation and then averaged all the boxes. That’s what’s called “linear” in the biz.
I did a lot of work with box models, partly because it was easy to test chemical mechanisms with them, and the results are easy to understand also. And I got to thinking about that “ventilation rate.” And wind power.
See, if you extract energy from the wind, it slows down, and that will have an impact on the ventilation rate of any area whose air is passing by the windmills. So I did some box model calculations on the amount of energy that was being extracted from the wind at Altamont Pass near San Francisco, plus the degree of pollution that was in the air that went through the Pass. That allowed an estimate of the increase in air pollutants that would occur in San Francisco due to the decrease in ventilation.
Okay, it was a weird calculation to make in the first place, but the results weren’t that deranged. There was an effect, the largest of which was equivalent to the amount of nitrogen oxides that would have had to be emitted in order to generate the excess of ozone seen at the pass. On a per kilowatt basis, it turned out to be a little less than the amount of nitrogen oxides that would be emitted by a natural gas-fired plant, such plants being the cleanest of all fossil fueled power plants. Of course the result depended on the amount of pollution already in San Francisco; a totally clean area would see no pollution equivalent at all, and since I made those calculations, SF has reduced pollutant levels.
I wrote up my results, sent the paper off to a journal, and then received some of the most flagrantly wrong referee comments I’ve ever received on a paper. One of them showed that I was “wrong” with a calculation that was itself off by five orders of magnitude, assuming, among other things, that wind speeds are constant all the way up to the stratosphere. I think he managed to calculate the wind kinetic energy over the entire Bay Area also, rather than just through the Pass.
Well, I know when I’m licked, and it was obvious that I wasn’t going to get anyone to pay attention to that wacky idea. Even in science, sometimes I’m too clever by half, and that’s a rueful comment, not a brag.

Castro
Anyone wanting to see some background to this, can visit Brad Delong's blog, here:
I first ran into the curious fact that Cuba had close to the lowest infant mortality statistics in Latin America over a decade ago, when I was boning up on epidemiology, partly as the result of a small contract I had, but also just because I do things like that every now and then.
In fact, Cuba's infant mortality rate is a bit lower than that of the United States. There are various claims that are made as to the source of this relatively minor statistical discrepancy, including noting that there are more low birth weight births in the U.S. due to a greater number of premature births, possibly as the result of more intensive pre-natal medical intervention. I'd be more receptive to such arguments were it not for the fact that non-Hispanic whites in the U.S. have a lower infant mortality rate than does Cuba overall, but infant mortality in African-Americans is more than double that of Cuba. For Native Americans it's about 50% higher than non-Hispanic whites, with considerable variation among tribal groups. Similarly, infant mortality is higher in some sections of the country overall, especially in the Southeast, but this may reflect the greater African American population there.
Of course, mentioning these facts immediately leads some to begin talking about "fetal alcohol syndrome," "crack babies," poor nutrition, etc. In the United States, you see, there are very few public health issues; it's always a matter of individual choices and responsibilities.
We're all such rugged individualists, you see. We cauterize our wounds by pouring gunpowder in them and then lighting it.
Anyway, I also noticed that, in any given academic article that addressed the issue of Cuban infant mortality, there was an obligatory first paragraph or two, explaining that Castro was, nevertheless, a Very Bad Person, a dictator, for heaven's sake, and the author certainly should not be taken as an Apologist for Castro. That would apparently make the author a communist, or at least a Left Wing something or other.
In "Rethinking Communism," I remarked on the fact that you can easily trace the outlines of the old USSR in southern Asia by looking at literacy statistics. The Russian Communists believed in teaching children to read, and they did something about it. And literacy, no matter what we'd like to think, is not a given. It requires some public policy decisions to result in a high literacy rate, and it requires a commitment of resources.
Cuba also has a high literacy rate, again, one of the highest in Latin America, a bit higher than that of Mexico, or even Costa Rica, and 'way higher than Guatemala, The Dominican Republic, or Haiti, to name some other countries that have had the benefit of U.S. invasions over the years. The Duchy of Grand Fenwick would not have been so keen on losing a war with the U.S. if they'd been in Latin America, I think.
So here we have Cuba, a dirt poor country, whether owing to the inherent inefficiencies in a centrally planned Communist economy, or to the fact that it has the most militarily powerful country in the world just a few miles away, trying to cut off all its trade, occasionally making invasion plans, and certainly requiring it to maintain a military far greater than it would otherwise need. (And let's stipulate here that Cuba also tried exporting its revolution and lent some of that military to Soviet purposes in Africa; I'm not trying to make the case that Castro is the Good Guy here). Yet Cuba, this dirt poor country, has managed to nevertheless maintain a effective structure of public heath and education.
Again, I don't think that this is all that mysterious. Those who make the decisions of public policy in Cuba decided that these things were a priority. In fact, you could argue that cutting off other, entrepreneurial avenues of advancement in Cuba, actually assisted the public health and education priorities, diverting manpower into those areas. I might personally think that you can do a better job with a richer economic base and a bit less labor input, but I'm not absolutely sure that this was an option.
Another thing that I'm pretty sure of is that ideas like "democracy" are rather secondary to the whole anti-communism thing. I don't want to try to gin up some sort of body count comparison between Cuba and, say, Guatemala, or to compare Pinochet to Castro. But it's undeniable that the United States routinely subverted (to put it mildly) democratically elected governments during the Cold War, in favor of dictators who were more "anti-communist." And this habit continues; how many people in the U.S. think it matters that Mahmoud Ahmadinejad is the elected President of Iran? Hell, how many even know that he was elected? Or that it isn't even the most powerful office in Iran? Very few, by the looks of things. Ahmadinejad's sole purpose, for U.S. foreign policy, seems to be to serve as a boogieman, someone to frighten the kids with.
Besides, if an election gives the wrong results, there are ways to make it all come out right.
But there is one other thing that has occurred to me in this ruminating-on-Castro thing, and that is this: the big foreign policy mistakes made by the U.S. concerning Castro were made in the early 1960s, on Kennedy's watch. There are those who try to blame the Eisenhower Administration, or even, so help me, Nixon (because Nixon was given such a lot of power during Ike's term, 'cause Ike trusted him so much). But Kennedy gave the go-ahead, and he did it because part of his thing was being as much of a "Cold Warrior" as anyone. The Cold War was not the invention of the Right Wing, they were the crazies who wanted a hot war. They were the "it's okay if that last two people left after nuclear war are Americans," people.
The Cold War was a product of American Liberalism. The Right learned to love it, or at least loved the anti-communist witch hunts. But Cuba was a bi-partisan screwup, and I think there's a lot of guilt still buried there. Some people are indeed such losers that they can't tell when they've won.

Linwood
Aside from his own flair for the dramatic and self-promotional extravagance, Lin’s greatest component was that of scholar, reader, and fan of fantastic literature, which included science fiction. That was what I found most attractive about him: the breadth and depth of his knowledge and appreciation for the history and literature of fantasy. He was also a natural storyteller, and more than once I read a work of fantasy that he’d described and summarized, only to be mildly disappointed in the actual work, since Lin’s summation had caught the essence of it and had improved on the presentation.

After he dropped out of advertising (yes, advertising) to become a full time writer, he made a good living for quite a while churning out pastiches of the popular “classics” of fantasy: Edgar Rice Burroughs, Robert E. Howard, Leigh Brackett, H. P. Lovecraft, Lord Dunsany, Clark Ashton Smith, and Kenneth Robeson. In the literary sense, he was least successful with Dunsany and Smith, both brilliant prose stylists, which Lin was certainly not. He was most successful, again in the literary sense (and this would be my own, probably idiosyncratic opinion), with his series featuring Zarkon, Lord of the Unknown, which managed to be both a pastiche and parody of Doc Savage, a finely walked line that required a near perfect tone. Commercially, I’m sure that the Burroughs and Howard pastiches were most successful; Lin caught the Conan wave at exactly the right time, and that humorless barbarian was easy to clone (the Thongor series)
and money in the bank.I’ll also mention one final attribute of Carter as a writer of fiction, one that was usually given short shrift, owing to the pastiche nature of most of his work: Lin could write humor. The only works where this really shines are in his two Thief of Thoth books (one of which contains one of my favorite bullshit lines of all time: “In n-space you don’t go any faster, you just cover more distance in less time.”) and the Almaric the Mangod story in the Flashing Swords #1. The latter contains the not unreasonable notion that an immortal adventurer must be rather dim in order to not go insane from the memories that accompany extreme age.
Lin’s first significant book of scholarship, Tolkien: A Look Behind the Lord of the Rings also came at an opportune time, and it and others paved the way for Lin to become the editor of the Ballantine Adult Fantasy series. Lin knew that it was only a matter of time before the Tolkien clones arrived, but rather than himself leading that charge, he took advantage of a window of opportunity to republish the classics of fantasy. If he managed to only bring Cabell and Dunsany back into print his contribution would have been enormous; that he managed to reprint practically every major and minor work of classic fantasy is an achievement so magnificent as to deserve secular sainthood.
Lin was one of the first science fiction and fantasy celebrities that I came to know well, another being Barry Malzberg a combination for which I must credit two members of the Albany Science Fiction Fan Federation (more or less originating at SUNY Albany), John Howard and Ben Sano. Ben was/is a Cabell and Dunsany fan, and Johnny would quote Malzberg’s writings back at him (Note to would be social climbing fans: writers love this. It’s almost as good as being young, attractive, and of the opposite sex).
As an aside, I’ll note that, owing the strange discovery of having mutual fans, Carter and Malzberg became friends, even at one point discussing a collaborative project of mutual interest, pornographic in nature. Go ponder what that would have looked like.
The Albany group, which Lin referred to as “The Albanians,” was an exemplar of fan behavior generally. At one party at Lin’s the toilet was malfunctioning, the handle mechanism having previously broken. Toward the end of the party, Lin confided to me, “Most of the fans I’ve had over here would have made jokes about it or just complained. You folks taught each other how to move the lid and use the coat hanger to reach the chain and flush it.” A little while later, he discovered that one of us had just fixed the mechanism.
His home at its zenith was a collector’s dream, not just for the books and artwork, but also the antique collectables such as the Japanese temple dagger, and the Enzenbacher sculptures. A good fraction of that left when Noel, his second wife, left him, but even after that, “Carter Manse,” was filled with interesting oddities which, of course, included the proprietor, his dog, the Mighty McGurk and sundry other pets, including a goldfish/carp that liked to gum fingers.
Lin tended to live extravagantly, as befitting his self-created persona, and when his luck turned, his extravagances did not serve him well. Similarly, his years of self-promotion had stepped on a toe or two (or twenty), and as money tightened, substantial portions of his collector’s paradise were liquidated, a sad end to yet another artistic vision. His precarious finances also had a hand in the complicated ending of the Gandalf Award, which I have written about elsewhere.
I saw him only a few brief times in his final years; Ben and other members of the Albany crew saw him a bit more often. I have heard from some who say that he became more irascible and impolite toward the end, as might be expected from someone disfigured by surgery and in constant pain, but I’ve not heard from any in the Albany group who ever found him to be anything but courtly and polite. I can’t speak for the others, of course, but I considered him to be a friend, and I believe it was reciprocal.
Lin died in 1988, of cancer of the mouth and throat, almost certainly caused by a lifetime of artful smoking, at the age of 57. This essay is in the nature of a memoir and a belated eulogy. My real tribute to Lin may be found here, and in my story “The Emperor of Dreams.” Godspeed, Lin, wherever that may take you.

Women and Snakes

Well, it's time maybe for a little meta-update here, and I must say that it's a little disappointing to have all this fine intellectual and pop culture fodder here, not to mention the wit and poignant memoir, only to discover that the main reason that people drop by here is to see Lisa Lyon wearing a snake.
Okay, okay, I get it. Women and snakes. I see the attraction.
I'm a little surprised that my essay on Black Snake Moan didn't get more attention, but that was a movie review, and didn't have any sexy pictures in it. Maybe I should have reviewed the remake of Bedazzled, and put the Elizabeth Hurley photo in it.
More pop culture reference, I was watching a CSI rerun on cable a few nights ago, the one about the UFO cult that thought we'd been invaded by lizard people, and there is some goofball saying something like "The Snake is a symbol of knowledge." Uh, yeah. Right. Knowledge. That's the ticket. That is absolutely what I'm thinking about when I see a woman with a snake. Knowledge.
As you might expect, there is an entire "Women and Snakes" fandom, no surprise there. Actually, I'd say that there are several, interlocking fandoms. There are guys who like to look at women with snakes, or photographs of women with snakes. There are photographers who like to photograph women with snakes. And then there are a lot of women who like snakes.
One person, who is in both of the last two categories seems to have a studio in Oakland, fairly near where I live, called "Snake's Kin Studio." Her site also has a number of videos, for those who like to be sure the snakes are still alive.
One of the sites these images come from has the specific disclaimer, "There is no pornography on this site." I pretty much agree, although I don't always know it when I see it.

Introduction to Blood Relations
Anyway, a couple of them kept at me about it. One of them pointed to various figures in fantasy and SF who were pretty monstrous, and he said, "So what could Honlin have done that was worse than that?" So I told him. And he said, "Okay, that's worse. You're going to have to tell the story though, one way or another."
So I began writing the next book, with the understanding that, somewhere in it, Honlin tells at least the bare bones of what happened, but it had to be to the right person, in the right circumstances, and I was really going to have to sweat to make it work out. Somewhere in the first few chapters, another of the writers group got me to give her something about what was coming, and she said, basically, "Yuck! I'm not sure I want to read any more of this." But she did, and eventually came to the opinion that I'd managed to pull it off.
Maybe the past ten years or so have coarsened our attitudes about some things, so maybe it won't be as much of a shock now. Some pretty horrible things have been done in our names in the past few years, after all, and some people seem quite comfortable with it. So maybe we were all just squeamish and now we're fuddy duddies. Still, it seems to me that there is a lot of effort being expended on rationalizations and excuses and all the other ways of avoiding the idea of personal responsibility for brutal behavior. But I'm interested in someone who did something without excuses, without trying to rationalize it as ultimately being "for the greater good," even if it were possible to make the case, even if there were people telling him all those things, to try to make it all okay. But he knows that it wasn't okay. There are some things beyond excuses; there are some things that may be even beyond redemption. However much one might yearn for it, and strive for it, eventually redemption fails. But one strives nonetheless.
So the story of Ed Honlin is about the striving, and the recognition that he will probably fail.
How's that for a teaser?

Laffering All the Way
The Laffer Curve is one of the greatest scams of all time. Really. "Please send me your bank account number so I can transfer $50 million in gold to your account" isn't even in the running compared to the Laffer Scam, though the Ponzi scheme might give it a run for the money.
The idea that you can somehow increase tax revenues by cutting tax rates is as seductive as 25% at no risk, though, isn't it? And it's so simple you can explain it to a child, using just the famous bar napkin:

Let's let the Wikipedia supply the basic, simple explanation:
"The curve is most understandable at both extremes of income taxation—zero percent and one-hundred percent—where the government collects no revenue. At one extreme, a 0% tax rate means the government's revenue is, of course, zero. At the other extreme, where there is a 100% tax rate, the government collects zero revenue because (in a "rational" economic model) taxpayers presumably change their behavior in response to the tax rate: either they have no incentive to work or they avoid paying taxes, so the government collects 100% of nothing."
Martin Gardner, in a famous Scientific American article, gave a satirical "neo-Laffer Curve," supposedly to show how fatuous Laffer's arguments were (Gardner's graph is rotated, with tax rates being on the y axis, and revenues on the x axis; the Wikipedia has a redrawn version in the same orientation as Laffer's original):

When I read Gardner's original article I was really pissed, because Gardner's graph fails on basic mathematical terms. A squiggle like Gardner drew isn't a function! So Gardner, the epitome of the punctilious math-head, let himself slide into a basic math error, simply because he was so annoyed with Laffer.
Moreover, he missed the most important mistake in Laffer's analysis. It is simply not true that a 100% tax rate generates no revenue, even in "rational" economics models, because there is no such thing as 100% compliance, among other things.
Consider the illegal drug trade. The criminal and RICO proscriptions on illegal drugs amount to a tax rate that is actually greater than 100%; there have been RICO prosecutions where people's houses and all their financial assets have been seized for a fairly small quantity of drugs, far less than the sale value of the drugs themselves. That's a greater than 100% excise tax. Yet the drug trade continues. Furthermore, various law enforcement agencies obtain substantial funding from RICO seizures, and a number of venues actually have excise tax laws on illegal drugs.
Hey, wait, no fair! exclaim the supply-side enthusiasts. We're only talking about the effects of capital gains taxation on investment and economic growth here. Or they'll claim that it's the effects of high marginal income tax rates on incentives to work or labor specialization.
Well, let's take that last one, which one might think would have a germ of truth to it. I remember a story from the Reader's Digest "Life in these United States" feature from many years ago. How many years ago will become apparent.
A man saw his neighbor out cleaning the leaves from his gutters, The man asked his neighbor why he didn't hire someone to do it, as the neighbor was an affluent professional.
"Well," the neighbor replied, "It would cost at least $10 to hire someone to clean my gutters, and I'm in the 90% tax bracket. So that means I'd have to earn $100 to get that much money after taxes. For $100, I'll do it myself."
It's possible to argue that cleaning gutters was an inefficient use of this man's time. And certainly his forgoing the hiring of it deprived the economic statistics of at least the $10 wage exchange, and possibly the extra hour or of the high income fellow's labor that he'd have surely worked if his marginal tax rate were less (I'm being sarcastic here, in case anyone is in doubt). But there are worse ways of spending a bit of time on the weekend than getting some exercise and seeing the neighborhood from a different viewpoint, to say nothing of the incidental inspection of the roof.
The point here is that even at 90% marginal tax rates, tax revenue was collected, it was not negligible, and the behavioral changes created by the "distortion" weren't necessarily always bad. People do not only work for money; if that were the only motivation in the world, I wouldn't be writing this, would I?
Moreover, by concentrating exclusively on monetary incentives, people tend to devalue the other incentives to labor, such as pride of workmanship and simple civic responsibility. The idea that a 100% tax rate results in zero labor implies that there is no volunteer labor—ever. This is the fallacy of Econ 101 Management.
As for capital gains taxes, well, the effective tax rate on investment in the old Soviet Union was 100%, as the Soviet government owned everything. It's quite true that the USSR did not have a particularly vibrant economy, but it did still have an economy. The government's effective "tax revenues" on invested capital were not zero. It was just that the government was the primary source of investment capital. And please don't anyone try to tell me that we don't have government capital investment in this country. Even ignoring basic infrastructure investment, we have a lot of government investment, from tax credits to outright subsidy and demonstration projects. It's just that most of these investments eventually wind up turning into private wealth, which, as it happens, is what happened eventually to a lot of the wealth that was created in the old USSR, once communism fell and "privatization" began. Then there is the case of the city that built a big baseball stadium so a certain future President could make some money on his investment in a baseball franchise. That was public investment in a private enterprise, no?
But let's say that we're still on the question of would a 100% capital gains tax yield no return. The answer is still yes. If someone wanted to sell their house in order to move to another house, and they had a capital gain on the sale of their house, would they refuse to sell, staying forever in the same house? Some would, but many would not. Many moves are not a matter of choice. They might try to balance the sale vs purchase to render a zero capital gain, but they would not always be successful, and there would be some revenue collected.
The fact is that it is very difficult to come up with realistic scenarios where a 100% tax rate generates zero revenue. The most basic assumption of the Laffer Curve is simply wrong.
Now you may think that I'm spending more time than I should attacking the basic premises and logic of the Laffer Curve and Supply Side Economics. Perhaps I am. Certainly SSE has failed every reasonable empirical test. In every case since the Reagan Administration, tax cuts have caused reductions in tax revenues, and the tax increases that have occurred since then never created the economic contractions that Supply Siders predicted.
Empiricism is tricky stuff, however, and the snake oil salesmen have been peddling the idea that when taxes are cut, all that need happen is for tax revenues to eventually reach what they had been before the cuts—which will generally happen in any economy that is growing over time. Eventually absolute revenues manage to increase, so long as the Supply-Siders don't actually wreck the entire economy, which they haven't managed to do—yet. In any case, such perversions of empiricism damand that a more fundamental attack be made.
The effect of squeezing revenues and increasing "defense" spending (which is to say, paying for wars and military contractor profiteering) over the past 6 years has been to deprive the nation of the investments that governments need to make, on infrastructure, regulatory oversight, education, and all the things that Movement Conservatives hate, because they don't fit into the basically feudal worldview that drives their actions.
And scams like the Laffer Curve need to be attacked at their roots, otherwise they grow back, like a thorny bush of carrion flowers, smelling like rotting meat to attract the flies that it needs to pollinate. And I'm no longer in the mood to cede these twits a single point. I'm no longer willing to give them even an inch.

More than One Way
Every high school is a small town, an enclosed community with its own rules and customs, some universal, some idiosyncratic. Joss Whedon famously pitched “Buffy, The Vampire Slayer” as “High School is Hell.” The response was almost universally, “And…?”
For a few, most often jocks and cheerleaders, at least in popular imagination, high school is the peak, and it’s all downhill from there. This also happens in college, of course, and all of this applies to the college experience as well. Irwin Shaw’s story, “The Eighty Yard Run,” is about a college football player who recognizes his peak experience many years after it occurs: a spectacular play in his last college game. It seems to offer him the future, but ultimately it becomes nothing but past glory.
For the rest of us, high school and college are prologues, where we are “cursed with great potential,” as Charlie Brown used to say. But even high school and college have more than one hill worth climbing, more than one status pyramid to scale. It is a tad ironic that the highest status for students at an institution of learning is seldom bestowed on those who, you know, actually learn, but there are usually some perks and privileges involved in being a high ranking member or the geek clique, maybe not enough to offset the danger of being bully bait, but you don’t have to be smart or good in school to be bully bait.
Besides, these stereotypes aren’t set in stone. There was more than one jock at Donelson High who was plenty smart and got honestly good grades. There was also my own idiosyncratic, Clark Kent-ish existence, where I compartmentalized my athletic identity at the downtown Nashville YMCA, accepting the bookish knurd label at my high school. I also avoided the awkward high school social scene by almost exclusively dating girls from other high schools.
There have always been these little private retreats from small communities. If one wants a more general escape, one could go to the big city, whichever one that might be, although for centuries that merely meant getting stuffed into some encapsulated community within the city. But at least cross-fertilization was easier. There are a lot more Juliets for the Romeo to find in the big city. Cities are big markets, and one of the markets is in spouses.
Modern transport and communication has broken down the practical barriers to escape from even the most isolated village, at least in this country. But more than that, modern American society has vastly multiplied the number of status hierarchies there are to join and climb.
In The Kandy-Kolored Tangerine-Flake Streamline Baby and later, The Pump House Gang, Tom Wolfe chronicled the emergence of strange and exotic sub-cultures in the U.S., hot rodders, surfers, and paparazzi, as well as profiling the icons of those sub-cultures, “Big Daddy” Roth, Dick Dale, Phil Spector, Murray the K. The books were revelatory, in the smacking-hand-to-forehead-and-exclaiming “Of course!” kinda way.
If I get a small enough group, I could be their leader…
Science Fiction Fandom was a very small pond until SF hit television and what would once have been cult movies began making mega-bucks. Fandom began as small clubs of geeks (almost exclusively male) who met through pulp magazine letter columns, then ironically bulked up as the magazine slowly died. There was also a time when it all melded, with comic books and D&D gamers side by side with costumers, RenFaire prithee-speakers, and Heyer Teas. Now, disaggregation is the order of the day, and comics or gaming conventions easily top the SF Worldcon in attendance. Moreover, the SF fan base is aging almost as rapidly as the Fox News viewership, and most under-30 convention attendees are legacies, the children of the earlier generation of fans.
Still, I expect the readership at least to get a nice final kick when the Boomers retire, giving many of them the time to catch up on their reading. So I still have some time to sell Dark Underbelly.
And anyway, there’s always Aikido. And I have this essay thing going on...

A Ducky and a Horsey
version.
We were crossing a bridge in the center of the park when he looked up at the sky and froze, transfixed by the sight of something. I followed his stare, but all I saw was clouds.
"Don't you have clouds on your planet?" I asked him.
"Oh, sure," he replied (his grasp of informal speech is getting good). "We have all sorts of clouds. Big and billowy, pale and wispy, the whole gamut, or so I thought. But I was wrong."
"How so?" I asked.
"Well," he said, turning to me and pointing. "These clouds . . . I can see pictures in them!"

Crybaby
There aren't any photos of me crying, but I did cry a lot as a child. One telling tale is the one my mother tells of me learning to walk. I would crawl over to the screen door that led outside, pull myself up via the cross slats in the door, turn, take a step or two, fall down and then cry for a minute. Then I would crawl over to the door and begin again. My mom says that I did this for hours.
So we see the early origins of the sort of whiney obsessiveness that has served me so well over all these years.
"High strung" is the phrase that is used for such emotionality, at least in the case of a golden child, for whom everyone makes excuses. My family was tolerant, as were many other adults. My friends were somewhat less forgiving, for the obvious, (and I concede entirely) good reasons. Nevertheless, I got away with it for much longer than would ordinarily be the case in the social system in which I grew up, i.e. the mid-South in the 1950s.
The same can be said of my precocious intelligence. There are some sub-cultures and ethnic groups in these United States where intellect is revered and properly encouraged and guided, but Tennessee in the 1950s was not one of them. Nevertheless, I was again protected from this knowledge for quite a while, by family and accident, plus the simple fact that, however precocious, a young child is generally tolerated, even by the most intolerant of adults.
The hammer finally came down when I was eight, in the third grade, in the form of Mizz R. (not her real name, though I use the correct southern spelling of Mizz). Mizz R. was not well-educated, nor bright, nor particularly good with young children. However, this was Tennessee in the mid-50s, and the three jobs available to white women were secretary, nurse, and teacher. The growth industry was in elementary school teachers. During the peak of the Baby Boom the whole country was throwing up schools like crazy, then putting "portables" behind them to hold the overflow. Class sizes were in the mid-30s, so just keeping control of a class could be an issue.
Given this setup, you can see how it can be a real problem when you have a third-grader who knows more about English grammar and is quicker at arithmetic than his teacher.
One irony of it all was that I still thought that Authority was on my side, or at least on the side of the correct answer. I'm sure that, at the beginning, I thought that I was being helpful when I pointed out the errors that Mizz R. made in class. Truth to tell, if she'd had one whit of sense to her, she'd have taken me aside, explained to me that blurting out corrections in class was disruptive, and that she'd take it as a personal favor if I'd write down any errors I spotted and then slip them to her later, so she could correct the problem in the next class. I'd have gone for that. I'd have even made it "our little secret." It would have been easy to turn me into teacher's pet.
Instead, she was on my case all the damn time. And she really went after my "weakness" which is to say the fact that it was fairly easy to make me cry.
Intriguingly enough, the place where the weepiness really manifested was "playground," the elementary school precursor to "gym class." This meant sports of one sort or another, especially softball in the fall and spring. That was always a weak spot; I tended to cry if my side lost a game. So I was branded a "crybaby," by my teacher and fellow students.
I reflect on this a little and there's a hint of the weird to it, because sports is one of the few places in southern culture were crying after a defeat is acceptable. Even fans are allowed to cry if you've just lost "a big one." But no matter, there was the chink in my armor and Mizz R. slipped the knife in.
So I did what most of the other boys had already learned, from their fathers, or peers, or whomever. I learned to hold back the tears, to cover the reaction with other emotions, especially anger, and resentment. And, I suspect, this led back to more bickering in class, because now I was angry a lot, and I was not misdirecting my anger. No, I knew who the problem was, even if I didn't know all the whys and wherefores.
Some later teachers knew how to harness the little mutant that they'd been presented with. My fifth grade teacher had me working on science demonstration experiments after I'd finished all my other work. (One part of the fight with Mizz R. was over homework. I didn't like carrying books home; she thought that kids should have to do homework. So she kept piling on the work, I kept doing it while still at school, and the other kids suffered the consequences. Sorry guys. My bad). My sixth grade teacher simply let me read in class, so I read the entire World Book encyclopedia during the school term.
Other teachers were, like Mizz R., undereducated bullies, and I locked horns with plenty of them. I believe I held the record for being tossed out of Mr. R's (no relation) eighth grade class, but really, what can you say to someone who has just finished explaining to the class that satellites stay in orbit by balancing the gravitational forces between the Earth and Moon? I don't think I actually called him an idiot; I believe that I said, "That's idiotic."
Well, the interesting thing about all that was that it provided a bond between me and my fellow students. Sure, some of them resented the "brain" that was among them, and thought me full of myself and conceited (fair cop, that). But they knew that my fights with the teachers was their fight as well, and that my occasional victories, or even fights to the draw, gave them some covering fire for their own independent actions. There were times when I got thumbs up from the lower stratum, the shop guys, the "hoods" and "delinquents" as they were nicknamed. And more than one of them turned out to be a pretty decent guy, go figure, just somebody who, at one point or another in the past, had refused to knuckle under.
There was, of course, lasting damage, if one wished to call it that. Like so many men, I do not cry easily, even when it is appropriate to do so. I feel the lachrymatory reflex begin and a counter-reflex pops in, that choked up feeling that says, "No, not now. Hold it in. Don't show the weakness."
But I am fortunate. I know the methods of displacement, projection, identification, and the uses of fantasy and art. I am fairly good at this writing thing, and sometimes I can strike the right balance between distance and emotion. Sometimes I can pull my own strings and write something that can make myself cry.

Taking Your Lumps
Now suppose you have a bunch of butane molecules flying around in the air, and the air also has some hydroxyl radicals (HO) in it. Every now and then, in accordance with the laws of statistical mechanics, one of the HOs will hit a butane molecule. Then what?
Well, most of the time, they just bounce right off each other. The hydroxyl is pretty reactive, radicals often are, but unless it hits the electron cloud of the butane in the right spot, with the right energy, etc., it’s just going to bounce. But every so often, it does hit right, and it grabs one of the hydrogens. Which one?
Well again, it will be the one it hit, but some of the hydrogens are more labile than others, so the HO is more likely to bounce if it hits one of the methyl groups, which have “primary” hydrogens because they are on primary carbons, and more likely to react if it hits the alkyl chain, on a “secondary” hydrogen.
Butane is nice and symmetrical, so there are only two possible outcomes. Due to symmetry, any primary hydrogen reaction looks like every other primary hydrogen reaction, and every secondary looks like every other secondary reaction. The hydroxyl always extracts a single hydrogen from the butane, which gives water, and an alkyl radical that immediately reacts with oxygen, and under smog conditions goes through a series of reactions that lead to either buteraldehyde, if the primary carbon was involved, or methyl ethyl ketone (MEK) if the secondary carbon was involved. (Actually, I’m ignoring some other pathways that get more important as molecular weight increases, like the formation of alkyl nitrates, and the times when the molecule fractures in the middle to produce acetaldehyde and an ethyl alkoxy radical. Having read that sentence, I’m sure you can appreciate my ignoring some details).
We can write a bunch of reactions for all this, assign rate constants to the reactions, put in temperature and pressure dependencies, etc. but the thing I want to point out is this: we’re simplifying a lot of events into a small set of descriptive equations. All the bounces are ignored, except insofar as they affect the reaction rate constant. All the different ways the molecules hit each other, along with the different energies of those collisions, all lumped into a few basic equations. We’re also taking advantage of the symmetries, by saying that reactions at either end carbon are equivalent, which they are, unless we had some way of telling the difference, like if one end or the other was isotope tagged.
Anyway, we’ve put all these things together and called them “reactions of the molecule.” That’s what chemistry does.
Now suppose we want to study the reactions of a number of different molecules, say add some pentane, hexane, heptane, and octane to the mix, and put in all the possible isomers of those compounds as well (there’s only one other isomer of butane, called isobutane, but toss in some of that as well). Now, how would you write your chemical equations?
You could try to write the equations for every single molecule—provided you wanted to go crazy, blow your computing budget, and not have the rate constants for even a tenth of what you wanted. You’re going to have to estimate that last one anyway, of course, though you might cheat and get some empirical data describing the reactivity of your mix.
You could look at what you have in the way of a mix and try to come up with some idea of an “average molecule.” That can get a little strange, because you’re going to have equations that account for some fraction of a carbon, for instance, and averaging rate constants is pretty iffy anyway. The fast reacting compounds will react away most quickly, so the “average” rate constant is going to keep changing. Nevertheless, you can do it, either as a constant average rate or as a continually changing average rate. It’s been done, though most often as a constant rate.
You could take your mix and wave your hands a little bit and say that it should look like some other, simpler mix, 45% butane and 55% octane, maybe. Of something like that.
The first one of these has come to be called the “explicit mechanism” approach. The second is the “lumped parameter” method. The third is a “surrogate mechanism” which is an explicit mechanism that is used on a reduced number of “surrogate compounds” to represent a more complex mixture.
All have been used in smog chemistry models, and all have their limitations. The mechanism that I first encountered was a lumped parameter mechanism called the Hecht-Seinfeld-Dodge mechanism. At that time I was coding what is called a Lagrangian Trajectory model version of the more elaborate Eulerian Grid model that had been developed by the research/consulting firm that employed me, then named Systems Applications Inc. One of my tasks was to code up and test the HSD mechanism in the simpler model.
At the same time, Gary Whitten (later to be my boss, because he was the only one who was willing to have me in his group, me being the charmer that I am) was attempting to use the HSD mechanism in an atmospheric application. He quickly ran into the problem that he had no idea what the “average molecular weight” of an average atmospheric hydrocarbon was, and there were parameters in the mechanism that depended upon that average.
What he did have was what are called “flame ionization detector” measurements of total reactive hydrocarbon, “as carbon.” In other words, he knew about how many carbon atoms there were, just not how many molecules they comprised. There were also a few gas chromatograph measurements that could be used to estimate the molar fractions of olefins (there were no real mechanisms for aromatic hydrocarbons at that time), but the breakdown of the alkyl hydrocarbons just wasn’t there.
Then he had an idea. I still think it was brilliant.
It turns out that the reactivity of an alkyl hydrocarbon (like butane, pentane, hexane, et. al.) goes up with increasing molecular weight, primarily because there are more carbon groups. In fact, the reactivity of any given primary, secondary, or tertiary carbon group is largely constant from one hydrocarbon to another, and if you normalize the reactivity by carbon atom, it’s reasonably close (within 20-40%) to constant. (This neglects the very lightest hydrocarbons, methane, ethane, and propane, because they are anomalously unreactive, but that also means that you can ignore them, mostly).
So Whitten devised a mechanism that ignored the idea of molecules for alkyl carbon. Instead it treated each carbon atom as a single “reactive structure” and did all the chemistry from there. He called it the “Carbon Bond Mechanism,” and its descendants are still the primary photochemical air quality chemical mechanisms used in air quality management in the U.S. (and elsewhere).
It wasn’t my idea, but I took to it like a duck to water. (So much so, in fact, that some people wound up thinking it had been my idea in the first place, something I later recognized as “ageist” since I was the young ‘un of the team. So I always tried to make sure everyone knew it was Gary’s eureka moment). The CBM had exactly the sort of “thinking around the corners” style that I love. And, it was practical. It made everything easier, emissions inventories, comparisons to air quality data, coding the mechanism. It’s actually a bit difficult to conduct “mechanism comparison studies” among other kinds of kinetic mechanisms in the U.S. because practically every emissions inventory is in the form used by CBM, and a fair amount of the differences between mechanisms is how they treat the emissions inventories.
Over the next few years, we devised a lot of twiddles to make the edges work, like an “operator species” that took intra-molecular reactions (like chain breaking) into account. We also extended the mechanism to include aromatic hydrocarbons, and biogenics such as isoprene and terpenes; those wound up being closer to explicit/surrogate mechanisms. I also came up with a cute trick that involved treating very reactive olefins as if they’d already reacted to their carbonyl containing products (aldehydes and ketones) because they reacted so quickly that their products were more important than the original compound. Not to get too egomaniacal, but it was all very cool.
Now let’s take this up a few levels of abstraction.
If you’ve managed to get through all this technical verbiage, one thing you might have noticed is that this sounds more than a little bit like engineering. We were designing a kinetic mechanism, for particular purposes, based on the resources (time, knowledge, computing power) that we had. Our goal was the construction of an atmospheric chemical kinetics simulation model, a tool that could be used for both scientific and air quality management purposes. If science is devoted to the acquisition of knowledge, what do you call something that assists in environmental management? Again, a lot like engineering.
Science operates on the model of “objective reality” and scientists like to think of themselves as dealing with that reality in an impersonal way. You can see that in the way that scientific papers are written, frequently in passive voice, rarely with individual actions described, and even more rarely as anything where the “arbitrary” is even acknowledged. The idea of choices is largely absent, because choices are the product of subjective individuals.
Art, on the other hand, glories in the subjective, the experiential. Choice is part of its very nature. Art is personal, and artists have no problem with the idea that their ego is involved. That’s part of the point of it. But it’s still often the case that some artistic element “has to be that way.” The artist feels like there is no choice in the matter, because making a different choice will lead to inferior, or even bad, art.
I’ve had careers in both science and art, and for a long while I thought that the art was for personal expression and the science was for the satisfaction of my curiosity about an objective world that was entirely independent of myself. I also had the notion that engineering was where the two met, where one applied the objective knowledge of science in service of the subjective needs of human beings, and those needs included the application of artistic principles to engineering, and engineering principles to art.
It’s a good line of patter, and there’s some truth to it, but as time goes on, I see more and more holes in it. For one thing, while art may be personal and expressive, it’s often pretty generic, and it starts looking a lot like other art. No one else would have written Book of Shadows, but if I hadn’t, there might very well have been another novel of “heroic fantasy,” in that publishing slot, and many of the same people might have read it and taken the same enjoyment from it. SunSmoke is a lot less interchangeable, in my view, but that is not necessarily obvious to the reader. I myself tend toward the idiosyncratic both as writer and reader, but most fiction, most art, is average; that’s what average means. And some proportion of popular entertainment is largely interchangeable with its near equivalents.
One the other hand, a great deal of science is more idiosyncratic, less objective, more personal than most scientists would admit. What is studied, how it’s studied, what sorts of theories and models are created, what sort of notation is used, all of that betrays the human face staring at the instruments, drawing the conclusions, writing up the results. Someone has to want to know the answer to the question that is being asked. Science is a human construct, no less than any other human construct, and to deny it is to deny both one’s self, and the truth.

Terry
And the leaves hanging down
And the grass on the ground smelling sweet
Move up the road
To the outside of town
And the sound of that good gospel beat
Sits a ragged tent
Where there ain't no trees
And that gospel group
Telling you and me
It's Love
Brother Love's Traveling Salvation Show
Pack up the babies
Grab the old ladies
Everyone goes
Everyone knows
Brother Love's show
--Neil Diamond, "Brother Love's Traveling Salvation Show"
The Congressional Record contains many interesting items, especially from the days when a filibuster actually required Senators to continue speaking for the duration. Often a filibustering Senator would read from a book, insert cooking recipes, and the like, just in order to keep the words flowing. Nowadays, not only is this not required, owing to a thing called Senate Rule 22, which allows some Senators to say "we're filibustering," and then a cloture vote determines whether or not the bill is blocked.
It's also quite possible for things to show up in the Congressional Record that were never actually said on the floors of Congress, and things that are said may be taken back, the CR being amended to nullify the past, and isn't that the way it ought to be with everything?
I doubt that my name was ever said in the Hallowed Halls, but it does appear in the Congressional Record at least once, as a citation of an EPA report in the background documentation for some air quality legislation (you'd think I could be more specific, and I probably could, but there are limits to how much work I'm willing to put into these little memoirs). It was, as I recall, a monthly report that later went into a document sometimes cited as just "Killus et al." (heh, heh), primarily because I was co-author to a majority of the individual chapters. The final publication was titled "Continued research in mesoscale air pollution simulation modeling. Volume 5: Refinements in numerical analysis, transport, chemistry, and pollutant removal" [Final Report, Oct. 1979 - Jul. 1982] KILLUS, J P; MEYER, J P; DURRAN, G E; ANDERSON, G E; JERSKEY, T N.
The full report included new transport algorithms, chemistry, actinic flux calculations, aerosol formation mechanisms, and surface uptake models for a photochemical grid model. The subsection that went into the CR was on the surface uptake mechanisms, i.e. the way that pollutants are absorbed or otherwise destroyed or transformed by interactions with surfaces, and I co-wrote it with the last guy cited, Terry N. Jerskey.
We didn't really work that closely together, having broken up the problem into piece parts with Terry doing some chunks of it, and me the rest. But there was a fair amount of time sitting across the table from each other, talking about this or that aspect of things like surface resistance, diffusional transport in the planetary boundary layer and other nurdy things that we were being paid to talk about. It was a lot of fun, actually, for me at least. I hope Terry enjoyed it.
Terry's hands shook by that point, a tremor that was a side effect of the medication he was on, I think it was Haldol, but this is a 30 year old memory here, and he only told me once.
One day, late, after everyone else had left the office except Tom, who was a chronic workaholic, Terry went over to the shopping center across the street and bought several bottles of dry cleaning fluid, which he proceeded to swig down on the way back to the office, tossing the bottles into the trash cans on the way back. He made it back to the office and collapsed on the hall floor, where Tom found him a few minutes later.
In addition to being a workaholic, Tom was also a member of the Ski Patrol, and strong as an ox besides. Both turned out to be important, because, after he called for the paramedics, he had to use that strength to pry Terry's jaws apart, in order to give him mouth-to-mouth respiration. Terry's jaws had become locked with muscle spasms, you see.
Then, after the ambulance arrived, Tom raced across the street and located the bottles of cleaning fluid (which I suspect he'd tasted in Terry's vomit and breath during the time he was doing Terry's breathing for him) and reported what Terry had swallowed to the ER by the time Terry had arrived.
This wasn't Terry's first suicide attempt, it turned out. That was the reason for the anti-depressants. In fact, I heard that Terry's wife was pretty blasé about the matter when she was called.
The next day, Terry was sitting up in the ICU, alert, seemingly fine. He told everyone who visited that he'd be back at work pretty soon.
The next day he was dead. The cause of death was "aspirated pneumonia." Vomiting cleaning fluid and then breathing it into your lungs causes damage, and there was enough damage for entirely different fluids to build up in his lungs—enough to kill him, in fact.
The only thing that I ever learned about Terry other than our working together was that he loved Neil Diamond, even the later pretentious stuff like "Longfellow Serenade." When we spoke about Neil, I'd always talk about songs like "Brother Love's Traveling Salvation Show," because I could honestly say that I liked it.
I honestly liked Terry, too, but not nearly enough, really. For the most part, he was just a guy I worked with for a while.

It's Always about the Blood
Bone marrow makes blood cells. More specifically, it contains various "uncommitted" stem cells that remain in the marrow while splitting off cells that then are "committed" to maturing into cells that circulate in the blood.
The biggie is the red blood cells, without which you and I would die in seconds, since they are what convey oxygen from the lungs to everywhere else. The fancy term for red blood cells is erythrocytes, which has the interesting characteristic of being not only less informative than "red blood cells" but also has more syllables.
The lab measurement for red blood cells is called "hematocrit," and 35% to 55% is considered normal. Less, and you have anemia. More, and you may have a blood disease, live at a high altitude, have dengue fever, or are taking a performance enhancing drug, like EPO.
White blood cells are "leukocytes," or ""lymphocytes" (hooray! same number of syllables, plus there's a differentiation in kind. That's what technical terms should be about). There's an entire menagerie of white blood cells, having to do with which part of the immune system is in play.
Then there are platelets, aka thrombocytes, which aren't exactly cells, but I'll get to that. A normal platelet count is between 150,000 and 400,000 per cubic millimeter of blood, but the ",000" is usually dropped in reporting, so a person with a platelet count of 200,000 is usually said to have a platelet count of 200. A low platelet count is called thrombocytopenia, and may create problems with bruising, bleeding, etc. although there are other factors involved. A count of 120, for example, is not considered that big a deal, but if the count drops below 20, the risk of spontaneous bleeding becomes very high.
Platelets aren't cells, per se; they are more akin to cell walls, hence the "plate" part of the name. Platelets are formed in the cytoplasm of a very large cell, the megakaryocyte. Megakaryocytes mature in about 10 days, from a large stem cell, the megakaryoblast. The cytoplasm of the megakaryocyte fragments at the edge of the cell. This is called platelet budding. The spleen serves as a holding tank for platelets, and contains about a third of the blood's platelets at any given time. Platelets are destroyed by macrophages, and have a lifetime of between 8 and 12 days in the blood, so the full life cycle of a platelet is on the order of about 20 days.
Platelets are necessary but not sufficient for blood clotting. A blood clot consists of a mass of platelets enmeshed in a lattice of insoluble fibrin molecules. Platelet aggregation and fibrin formation both require the proteolytic enzyme thrombin, plus calcium ions and about a dozen other protein clotting factors. Most of these circulate in the blood as inactive precursors until they are activated by trigger enzymes that form when blood vessels are ruptured or something else unpleasant happens.
So, basically, platelets are the bricks and the aggregation factors are the mortar, glue, etc, that hold them together to form blood clots. This entire process is pretty much unique to mammals, incidentally.
There are a number of drugs that will reduce platelet count, including the aspirin-like drugs, ibuprofen and naproxen. I was taking prescription-level amounts of naproxen until recently, owing to the practice of Aikido, and this did lower my platelet levels to somewhat below the lower level of normal, which is to say 100-150, but I did not seem to have any clotting problems, so big deal, was my opinion. However, a few months ago, I began a series of encounters with a fine (intentional irony here) drug called Temodar, which really slams the platelet count, so I had to give up the naproxen. I now report that this made me feel roughly 10-15 years older on the Aikido mat.
A fellow Aikido student recently underwent a root planing, a dental procedure that removes accumulated plaque from below the gum line. After finishing one side, the dentists said, "There's too much bleeding here. I'm not going to do the other side without a doctor's release." So, said student went to his doctor, who sent him to get the requisite blood test.
Upon receipt of the results, the doctor called and told him, "I want you to immediately go to the nearest hospital and check yourself in." The student then called a friend of his, also a physician, for advice. Upon reading his friend the blood test results over the phone, the friend said, "What are you doing talking to me? Go to the nearest hospital and check yourself in immediately."
Our boy did not quite follow the advice. He first wrote up a list of things that needed doing at his job, then he went, not to the nearest hospital, but to San Francisco General. This was actually a good move, because they immediately sent him over to UCSF Hospital, where they could make a proper diagnosis, and where he is now just about done with the chemotherapy for the rare (and, fingers crossed for the happy ending) and very curable form of leukemia that he had developed. Upon admission, he was immediately given a transfusion, and has since had 6-8 "platelet packs," which consist of platelets that have been centrifuged out of whole blood.
He is 36.
His blood test platelet count was 11.
Observing
When I was seven, we had a siamese cat. Actually, it was a kitten; the little idiot never made to cat-hood. First he nearly drowned in the toilet, then he took to hiding atop the tire in the wheel well of the family automobile, to predictable results.
[In the previous paragraph, I’m engaging in either “blaming the victim,” which is usually thought of as a product of “identification with the aggressor,” or “reaction formation,” the covering of one emotion—sadness at the loss of a pet—with its opposite, or near opposite, in this case disdain. If I were to say that the kitten would be long dead in any case, given the life span of cats, I’d be “rationalizing.” Spending this much time analyzing my own reactions is an example of “intellectualizing.”]
In any case, one of the bonding events with the kitten was mediated though annoyance: he would jump up on my bed very early in the morning, like 4 or 5 A.M. and knead my chest while mewing to wake me up. It couldn’t have been hunger, because I didn’t feed him. Maybe he was just lonely.
One morning when he’d awakened me this way, I was intrigued by a pretty spectacular spectrum display on my bedroom wall. I investigated and it turned out that a shaft of light from the morning sun had gone through my aquarium before it hit the wall. The aquarium had acted like a prism, one with an internal reflection, in fact. Later I got some “pop sci” books on light and optics and read up on the subject.
Many years later, while flying home from college, I noticed some color on the cover of the book I was reading, which caught my attention because the cover was black-and-white. I knew that surface reflection of light is usually polarized, so I got out my Polaroid sunglasses and looked at the window of the plane. Sure enough, it showed spectral splitting of light, and the pattern looked like it was a strain pattern. A bit of reading later further informed me that looking at plastic strain via polarized light is an industrial testing procedure to check for defects in the plastic. The plane’s window pattern had been nice and symmetric.
I took further advantage of the sunglasses trick once when I was down in Los Angeles with my then housemate, Steve and some of his friends. Driving on 101, I noticed that the San Fernando Convergence Zone was clearly visible that day. The SFCV results when air blowing in from Los Angeles meets air coming from the other direction from Ventura County. Such convergence zones are common features of air flow near mountains, in this case the Santa Monica mountains.
Because the air from LA is more polluted than the air from Ventura, the SFCV has a clear demarcation, and it pushes air up above the nominal inversion height. I pointed it out to my companions, but several of them had to look at it through the polarized filter in order to see it. Polarization helps identify polluted air masses, because the fine particles exhibit surface scattering (Mie scattering) that is polarized. One of the people in the car said, “You know, I’ve lived almost my entire life in LA and I’ve never noticed that before.”
A while back, in the dressing room of Eastshore Aikikai, I noticed a circular spot of light on the floor. What caught my eye was the precision of the circularity. I looked up to the roof and spotted a small hole in a fan covering, and I realized that we actually had a pinhole camera in operation, a camera obscura. The reason why the light was perfectly circular was that it was an image of the sun. I’ve studied it since then and on partly cloudy days you can see the clouds move across the face of the sun. I suspect that if we had a better surface—smoother, whiter—it might be possible to make out sunspots.
Judging from its rate of travel across the floor, the camera obscura only operates for at most an hour a day, and I suspect it only does so for a few weeks or months per year. We'd only recently began classes in the middle of the day, and only one day a week, Sunday. So it’s not surprising that no one has noticed it in the year we’ve been there.
The other variable is having someone there who might pay attention to a spot of light on the floor, and wonder why it was so round. I have no idea of the odds on that, other than to suspect that they’re not very high.

Faster
Edison, being partly deaf, was somewhat more interested in sound than Einstein, who was more of a light man, as it were. Still the speed of sound, as a principle, is mighty important; it just varies with a lot of things that were, to be fair, of interest to Einstein as well.
Sound propagates when atoms bump into each other, so it's important how fast the atoms can go, and the nature of the bumping. In solids and liquids, where molecules are sitting right next to each other, as it were, the forces between them, the elastic modulus is the critical factor, as is the nature of the wave that is being transmitted. Molecular movement in solids is also quantized, with the pseudo-particle being the phonon, which represents the quantum levels of forces transmitted from one molecule to another.
The speed of sound (SOS) in gases depends on how fast the individual molecules of the gas are moving, since any individual particle must actually traverse the distance between it and the next particle for momentum to be transferred. So there we get into all sorts of cool things like ideal gas laws, heat capacities, and statistical mechanics, some of which Einstein did have in his thoughts.
In the simplest approximations, the speed of sound for a gas is determined by two factors, the molecular weight of the gas and its temperature. The speed of sound is always limited by the RMS (root mean squared) molecular speed; the two are related via a fairly simple relationship:
RMS/SOS = Sqrt(3/BM)
where BM is the bulk modulus of the gas, it's resistance to pressure. For a diatomic gas, the bulk modulus is 1.4, so the ratio of RMS to SOS is about 3/2.
In rockets, the oomph that any given propellant will give is limited by the velocity of the exhaust gases. So basically you want your exhaust to be very hot, with the lightest molecular weight you can manage. In Rocket Ship Galileo, Heinlein had his protagonists use zinc as the propellant (heated via nuclear reactor), and has one of them muse that he'd have preferred to use mercury. This is, of course, almost exactly backwards, and Heinlein did a better job later, in, for example, Space Cadet, where "monoatomic hydrogen" is supposedly used.
Monoatomic hydrogen would indeed be a good rocket propellant, pretty much the best possible, if you could use it. However, the temperature at which diatomic hydrogen (which is to say, hydrogen gas) dissociates into atomic hydrogen is mighty high, in the thousands of Kelvin, and would probably destroy any rocket nozzle that could ever be built. As I recall, Heinlein had tanks of monoatomic hydrogen on his ships, no doubt made out of unobtainium metal, with a bolonium catalyst to keep the hydrogen atoms from recombining.
Rockets are, as I've said before, a horribly inefficient method of travel, since conservation of momentum means that you're hurling huge masses of material out the back end, and it�s taking most of your energy supply with it. In fact, the more "efficient" your rocket in terms of payload to fuel ratio, the higher the percentage of your energy supply is going into your exhaust stream.
Also, with chemical reactions as your energy source, you can't really use hydrogen as your exhaust gas, because it isn�t the product gas of the energetic reactions you'd like to use, always assuming that you don't actually have tanks of monoatomic hydrogen lying around. MH would produce some pretty hot molecular hydrogen when it recombined, so that would work. Too bad about the world wide unobtainium shortage.
All the speed of sound issues apply to explosively driven projectiles, aka "guns," as well, though such projectiles are much more efficient than rockets, energetically speaking. Mass drivers of all sorts have the advantage of using the Earth as a big momentum sink, and when you use something that large to absorb the recoil, it doesn't get much of the energy in the bargain.
You can't generally use hydrogen and liquid oxygen in a bullet (though there are some cannon designs that do), so typical muzzle velocities are limited by the average mass of the molecules in gases like nitrogen and carbon dioxide. Those have greater masses and hence lower particle velocities than does water vapor, to say nothing of hydrogen.
But then we come to gas guns, where the projectile is driven by compressed gas. Sure, you usually can't get the pressures in a compressed gas cylinder as high as you get from an explosive, but you can then use hydrogen, or helium as the gas. Helium, being honestly monoatomic, has only twice the mass of a hydrogen molecule, so its RMS and speed of sound is still pretty fast, which is why you get a high pitched voice if you inhale helium.
If you use a compressed gas cylinder, you have what is called a "single stage gas gun," which rather demands an answer to what a "two stage gas gun" is, right? Ah, there it gets interesting. In a two stage gas gun, you use an explosively driven piston to ram the gas into the compression chamber. Then, when it reaches a nice, high pressure (and remember, it's also been heated via compression), it ruptures a perforated valve and slams into the projectile, which is then propelled out of the barrel of the gun. Some designs preheat the original gas as well; you can exceed the melt temperatures for parts of the device for brief periods of time, and gun shots are nothing if not brief.

Lawrence Livermore Laboratory has a nice two stage gas gun that can propel a projectile weighing 5 kilograms to 3 kilometers per second. There were plans in the early 1990s, to upgrade the thing and to use lower weight projectiles, which would reach 8 kilometers per second, and LLL wanted to try putting things into orbit with it. Instead, absent the $1 billion upgrade, they had to content themselves with firing the thing into a liquid hydrogen target, experimentally demonstrating the existence of the previously only theoretical metallic phase of hydrogen. And even without quite so lavish funding, they do seem to have managed to get up to the 8 km/sec range, albeit with pretty light projectiles.
Theory doesn�t quite run out of oomph at 8 km/sec, however. As you go to higher and higher temperatures in hydrogen, you begin to get molecular dissociation. Heat your original gas hot enough, and compress it enough, and you can get a gas containing significant amounts of--wait for it--monoatomic hydrogen. I've seen a design document from The Rand Corporation on how to build one of those, and its theoretical top projectile velocity exceeds 10 km/sec. That's flirting with escape velocity and it's well over orbital velocity. It may also be getting close to the velocity necessary to compress inertial fusion materials to the point where a tritium-deuterium burn can occur, but that's a different essay, for another time.

One of the Places where it all Began
We were somewhere around Barstow on the edge of the desert when the drugs began to take hold. I remember saying something like, "I feel a bit lightheaded; maybe you should drive . . ."And suddenly there was a terrible roar all around us and the sky was full of what looked like huge bats, all swooping and screeching and diving around the car, which was going about 100 miles an hour with the top down to Las Vegas. And a voice was screaming: "Holy Jesus! What are these goddamn animals?"
Then it was quiet again. My attorney had taken his shirt off and was pouring beer on his chest, to facilitate the tanning process. "What the hell are you yelling about," he muttered, staring up at the sun with his eyes closed and covered with wraparound Spanish sunglasses. "Never mind," I said. "It's your turn to drive." I hit the brakes and aimed the Great Red Shark toward the shoulder of the highway. No point mentioning those bats, I thought. The poor bastard will see them soon enough. --Fear and Loathing in Las Vegas, Hunter S. Thompson
This is Now:
Saturday noon. Recollection of the last 24 hours is excruciatingly difficult; I have taken every remaining pill in my kit bag, and yet somehow, despite the presence of enough chemicals in my system to transform me into the Joker, I have developed a raging cold. My throat is nearly sealed shut, which may work to my advantage since I’m reaching the point at which the rude answers which bubble up in my skull every time someone speaks to me are threatening to spill over into actual vocalization. Ever since Wednesday I have been asking myself in re my pharmacopia: how many is too many? Crashing into every sharp corner in my hotel room, I know the answer: however many I took when I woke up this morning.
Last night was the Ronald Reagan Banquet, a dinner which was for and unfortunately not of Ronald Reagan. Eating a dehydrated teriyaki jerky chunk of the old fraud might have given me some of his strength. I’ve heard the words “Ronald Reagan” and “tax cuts” so many times now they’re beginning to lose whatever meaning they might have once had, and Will, that payola-stuffed bloviator of manifest destiny, will say them another three dozen times while I tuck into my mashed potatoes. After the ghouls-gone-wild reception given to Ann Coulter a few hours ago, the crowd receives him politely and respectfully, and even considering the fact that this is an older crowd, made up largely of the parents of the rich kids hooting and snarling at Ann’s anti-McCain jeremiad, it still has the tone of someone forced to hear their grandpa read cowboy poetry just after they’ve come back from yelling “SHOW US YOUR TITS!” to drunken frat girls. Will himself is perfunctory at best, showing his chipper cheerleader side only when discussing Old Mother Reagan; the rest of the time, he’s just there to pick up a check. He even senses the hostility in the room when called upon to mention the Supplicant McCain: urging the crowd to be “happy warriors” for the default candidate, he sounds like a bored Sunday school teacher leading his tenth consecutive round of “I’ve Got the Joy” for a group of sugared-up fourth-graders.--Mister Leonard Pierce, The Beast is Red, Chapter 12: Show Us Your Twits, from Sadly, No.
Corporate Libertarians
To be sure, Heinlein explicitly stated that a healthy society was essential to the individual, so he believed that individualists must also include the social good as part of their own. It’s a sophisticated position, and I only disagree on practically all the details, especially when it leads to things like the belief that Napoleon was some sort of triumphant individualist (a position sometimes attributed to Nietzsche, or that Cesare Borgia was a paragon of enlightened self-interest (Machiavelli).
Current libertarians are less keen on their own personal membership in the military, but they do often identify with collective behavior and groups. However, for a good many libertarians, group identification seems to be with the modern corporation, sometimes called “private enterprise.” I’ll also note that “value” is often assumed to be monetary, and nothing more. For commercial enterprises, of which the public corporation is a good example, that is pretty easy to understand. It’s not quite as clear-cut for individuals, but that mistake is obviously not limited to libertarians.
This “corporate libertarian” critique does not hold for all libertarians. There is, after all, no secret libertarian handshake, no membership card, etc. Anyone can call themselves a libertarian. Still, the most annoying ones are those who fail to understand that the limited liability corporation is a profoundly privileged beast, one whose existence weakens such things as the individual right-to-contract, and individual property rights in general. I will stipulate at the outset that I think the corporation is a very powerful and useful invention, but it does require certain sorts of regulation if it isn’t to seriously harm individual rights, and often corporate libertarians seem more interested in eliminating those essential regulations than upholding the underlying individual rights.
Let’s consider how this can work with an extreme case: contract murder. I’m sure pretty much everyone would recognize that a contract to perform an illegal act is itself an illegal contract, and totally unenforceable. Furthermore, it’s pretty easy to see that both parties in a contract hit (the killer and the one who pays for the killing) are guilty of criminal conspiracy.
What would be the effect of making such contracts legal, and absolving the one who takes out the contract from penalty? Obviously this would weaken criminal law, but less obviously, it would also weaken contract law, since it would set civil law against criminal law. In a similar way, the institution of slavery weakens the institution of property, by putting property rights into opposition to human rights. Property rights in the South during the Civil War were often pretty shaky, what with the armies marching through and all.
The limited liability corporation puts many decisions behind a financial “firewall.” Stockholders and their agents (corporate boards and management) can undertake actions that, potentially, have far greater adverse consequences than they would deem acceptable if their whole net worth was at risk, as it would be in a proprietorship. This means that when individuals enter into contracts with corporations, the exchange is even more one-sided than if it were a matter of an individual contracting against someone with greater resources.
The anti-environmentalism exhibited by many corporate libertarians is another symptom of psychological projection and identification. If, for example, individuals do not have a property right on the air they breathe, then property rights (and individual rights generally) are pretty much meaningless. Similarly, if I own real property that has a stream running through it, I possess certain rights that preclude those upstream from having absolute authority over that stream as it passes through their property. In common law, this would be an easement; Federal and State laws are usually even more explicit and restrictive—to the fury of anti-environmentalists.
Similar easement rights surely exist for such things as migratory animals, flood control, protection of ground water, ecological integrity and so forth. I have an interest in all of these that is best expressed (in my view) as a property right. However, since such things are difficult to monetize, they do not show up in corporate thinking. Generally, only individuals value such things, and since corporate “rights” trump individual rights, then the corporate libertarian inevitably leans toward anti-environmentalism. For that matter, so does anyone who cannot imagine any value except insofar as it can be measured in monetary terms.

Final Chapter, or Is It?
Brubeck and Desmond
The first cut to come up in the mix was “Blue Rondo a la Turk.” In Ken Burns’ “Jazz,” Brubeck recounts how he stole a good portion of it from Turkish street musicians when he was on tour while in the Army, thus making it one of the first examples of my exposure to World Music. It’s in 9/8 time. The liner notes for Time Out was the first place I ever saw the phrase “time signature.” I suspect it was like that for a lot of young boomers such as myself, and I’ve occasionally wondered how many of the out-of-the-ordinary time signatures in rock (I’m thinking of you, Fairport Convention) have a root or two in Brubeck.
A while later in the randomness came “Take Five,” one of the most famous melodies in all of jazz. I’m not sure how long it’s been since I’d heard the original, especially in true “high fidelity,” i.e. through headphones, with a minimum of background noise. And as gooseflesh sprouted on my arms, I wondered, did I just forget, or had I never really noticed before?
Gloria Steinem once famously quoted Paul Desmond as saying that he “wanted to sound like a dry martini.” That self-deprecating witticism masked an amazing achievement. Paul Desmond gave his alto saxophone a tone unlike anything else played by anyone else. He made the alto saxophone sound like a flute, breathy, clear, and smooth.
The saxophone is a naturally raucous instrument; it fits into rock and roll as easily as bebop. It doesn’t do mellow easily. Yet Desmond made it so. You might be able to find some early to middle Coltrane with that kind of fluidity (then later he turned against that early “cooler” style), but that’s almost the whole list. Gerry Mulligan was in the same country with the baritone sax, but I just can’t come up with a memory of anyone who sounded like Desmond on the saxophone. I will say that I've recently encountered a tone similar to Desmond's, from Kenny Davern, playing with Dick Wellstone. But that was from a session in 1981, and Davern was playing the clarinet.
A friend of mine once said admiringly of Carlos Santana, “He’s achieved every musician’s dream, a sound so distinctive that his mother could recognize it coming out of a car radio.” Paul Desmond did that with the saxophone. He did it in plain sight; everyone remarked on it, even. But it was an achievement both effervescent and evanescent, slipping from memory even as the final notes are played, with the “dry martini” remark serving as a place holder to something far more magical.
The Dave Brubeck Quartet, with Brubeck on piano, Desmond on sax, and Eugene Wright and Joe Morello on bass and drums, respectively, were the most popular examples of “West Coast Jazz,” sometimes derisively called “White Boy Jazz,” owing to a paucity of black performers in it. Brubeck, though, was a fierce integrationist, bless him, first integrating his Army touring group in WWII, then sometimes canceling gigs in the 1950s, if Eugene Wright was disrespected in any way.
Brubeck made the cover of Time Magazine, in November, 1954, the second jazz figure to do so (Louis Armstrong being the first). The story goes that Time debated whether to put Brubeck or Duke Ellington on that cover, and chose Brubeck. The two men happened to both be in Denver when that issue came out, and Brubeck tells the story of having Ellington knock on his door at seven in the morning, greeting Brubeck with, “You’re on the cover of Time!” when he opened the door.
Burbeck idolized Ellington and wished that the cover had gone to Ellington. Ellington was both a showman and a realist, assuring Brubeck that either way, it benefited jazz, and what was good for jazz was good for all of them.
I’m with the Duke on this one. Time Out was the first jazz album I bought, but it wasn’t the last. Every moment contains both the past and future. And something in all this evokes my memory of sitting on a blanket on the grass lawn of the College of St. Rose in Albany, New York, listening to the Count Basie Orchestra with some friends, and thinking that life is mighty good.

Hot Buttered
Diacetyl (emphasis on the first syllable) is also called biacetyl (emphasis on the last syllable) and the latter is what we called in when I was working on the photooxidation of aromatic hydrocarbons a couple or three decades ago. Biactetyl, in fact, occupies an important place in the history of smog chemistry, though I have to admit the notion of "important" is open to interpretation.
There are basically four kinds of "reactive organics" that are important in smog photochemistry: paraffins, olefins, aromatics, and carbonyl compounds (aldehydes and ketones), the latter being more commonly formed in the smog process than emitted outright. I'm taking a bit of a liberty here by omitting alcohols, ethers, and other oxygenated compounds, partly because, ethanol and MTBE notwithstanding, they still don't amount to a large fraction of the mix, and partly because their photochemistry is pretty close to that of paraffins, or ketones that don't photolyze, i.e. break up by the direct action of sunlight.
The early days of smog chemistry were dominated by research into the chemistry of paraffins and olefins, so much so, in fact, that it wasn't until the mid-1970s that researchers realized that the photolysis of aldehydes and ketones was the primary source of catalytic radicals in the smog formation process. In fact, that was the biggest single difference between the first photochemical kinetic mechanism that I worked with, the Hecht-Seinfeld mechanism, and the later, Hecht, Seinfeld, Dodge mechanism. The former used oxygen atoms (from the photolysis of NO2) as its primary radical source, whereas the latter used formaldehyde and higher aldehydes to that purpose.
Both of these mechanisms were based on smog chamber experiments involving butane and propylene (or propene, if you're a nomenclature purist). Aromatics chemistry was tacked on as an afterthought, not because it was believed to be unimportant, but more because nobody had any idea what to do with it.
Aromatic hydrocarbons, as they are called, all have a "benzene ring" somewhere in them, and that makes everything very complex. Perhaps you remember the story about Friedrich Kekule literally dreaming up benzene's structure. It's formula is C6H6, and its structure "bites its own tail," so each carbon atom, with four chemical bonds, has, after accounting for the hydrogen, three bonds to share with its two neighboring carbon atoms. That could work out to two and one or one and two, i.e. a paraffinic bond with one neighbor and an olefinic bond with the other, but the wonders of quantum mechanisms allows it to actually be one and a half bonds with each neighbor. Such are the wonders of quantum electrons being able to be in several places at the same time.
Benzene itself is almost dead, photochemically speaking; put it into a smog chamber and it mostly just sits there, making a little tang of phenol after a while, but phenol is deader still, so…boring.
But if you replace one or more of benzene's hydrogens with a methyl group (-CH3), now you're talking. One added methyl group gives you toluene. Two, and you get xylene, which comes in three isomers, meta, para, and ortho, depending upon whether the methyl groups sit right next to each other (ortho), on opposite sides of the ring (para) or one over (meta). There are also, of course, trimethylated benzenes, and compounds where the substituted groups are more complex than methyl groups. But actually, toluene and the xylenes make up the bulk of aromatic compounds in air pollution. There is even a refinery stream referred to as "TBX" which stands for toluene, benzene, and xylene.
Okay, so I'm going to tell you how the photochemistry works, then how it got figured out. The tricky part had to do with how the aromatic rings would open up. Everyone knew it had to happen sometime, but how, and what the products were was a mystery for years.
What happens to something like toluene in smog is that, when it encounters an hydroxyl radical (-OH), the hydroxyl adds itself onto the ring somewhere, usually at the carbon that sits next to a methyl group, because of the way that methyl groups mess with the electron distribution of the aromatic ring. This is what hydroxyls do with olefins, incidentally, so you can look on it as the hydroxyl briefly looking at the ring and seeing, not that "one and a half bonds" thing I mentioned above, but a double carbon-carbon bond, which hydroxyls just love to glom onto.
This breaks one of the carbon-carbon bonds, and one end of it now has a romantic relationship with the hydroxyl radical. But the other end, like a jilted lover, is on the rebound, ready to pick up with just about any pretty face that comes by. That face, almost always, belongs to oxygen, a really promiscuous molecule. It's diatomic (i.e. O2), but not so committed to the relationship that it passes up some good carbon bond action.
So an O2 gloms onto the other, lonely, carbon and you now have a peroxy radical, an aromatic ring with an oxygen tail. The radical characteristic of the thing tends to be concentrated at the free swinging tip of the tail, and in most peroxy radicals, that tip winds up reacting with some other molecule.
Not so with the aromatic peroxy radicals, however, because it so happens that the radical tip is just right for swinging around and hooking up with another carbon, somewhere else on the aromatic ring. You may now consider all of the other sexual double entendres that I could use for this situation.
Anyway, another oxygen now gloms onto the group, but now the situation is stable enough (maybe) so that it waits around for some outside compound (usually a molecule of nitric oxide—NO) to take the last lonely oxygen atom away from the daisy chain.
All the oxygens then decide to settle down with their new carbon best buddies. The oxygen-oxygen bonds call it quits, and that leaves another oxygen bond for each oxygen connected carbon. If you're counting, and remember that carbon only has four bonds to its name, this means that it has a double bond with an oxygen, one for either a hydrogen or a methyl group, and, whoops, only one left for another carbon in the aromatic ring. In short, the ring opens, in multiple places, once for each oxygen. At some point, the poor hydroxyl group, which is now the radical of the bunch, meets yet another oxygen molecule and the hydrogen leaves the party to for hydroperyoxyl (HO2).
The aromatic ring is pretty much finished at this point, and it cleaves into at least two pieces, one with two ring carbons, the other with four. The one with four has, in addition to two oxygen atoms, a olefinic bond (there was some belief for a while that the fragments might all have two ring carbons, each, meaning that there would have been another oxygen molecule bridge on the ring, but later product yield measurements indicate otherwise).
Both ring fragments are called "dicarbonyls" because they each have two carbonyl (C=O) bonds. In one of the fragments, the two carbonyl bonds are right next to each other.
The simplest dicarbonyl is called "glyoxal." It's just H(C=O)(C=O)H. The next one is methyl glyoxal, with a single added methyl group: H(C=O)(C=O)CH3. Both of these are very hard to measure; they tend to stick to gas chromatographic columns nigh onto forever.
Ah, but the next in line is a dicarbonyl with two methyl substituants: CH3(C=O)(C=O)CH3. This is called biacetyl, or diacetyl. And it comes through a chromatographic column.
If you photooxidize orthoxylene, with it's two adjacent methyl groups, when the ring opens, a certain percentage of time you get biacetyl. A group at the University of California at Riverside, (Darnall, Atkinson, and Pitts, 1979) saw the biacetyl coming off of their chromatograph and realized that they had seen the first evidence of ring opening products.
It so happens that both biacetyl and methylglyoxal photolyze like crazy, so much so that they last only a few minutes in sunlight before splitting into radical fragments. I had been looking for something exactly like these dicarbonyls in my own studies of aromatics photochemistry, because I'd found good evidence of very powerful radical sources in toluene experiments. My calculations indicated that the radical formation rate from toluene was twice what it would be if toluene were going to pure formaldehyde, which of course it does not. It forms a significant amount of methyl glyoxal, and that was what I was looking for.
Later, I heard that biacetyl/diacetyl was used to flavor margarine; I also heard that microwave food products use excess flavoring agents because the microwave heating process drives the volatiles away faster than regular cooking.
I had some vague suspicions that it might not be a good idea to use a compound as photochemically unstable as biacetyl in food. Light causes biacetyl to break into two pieces, both acetyl radicals, and when there is any oxygen around, you get peroxyacetyl radicals. Add some nitrogen dioxide and you get peroxyacetyl nitrate (PAN), which is biologically active. Actually, it's a good bet that any give peroxy compound is biologically active. These are some pretty potent radicals.
So then we see a story about the guy who loved the buttery smell of microwaved popcorn and got a rare lung disease, bronchiolitis obliterans. More to the point, "popcorn lung" has been added to the list of industrial diseases affecting production workers.
All I had were a few suspicions, of course. Nothing to go on, really. But I can't say that I'm surprised in the slightest.
Object Oriented
As noted in the write-up, I undertook the color cycling project because of a long standing love for that particular effect in computer graphic art. It’s a simple trick; it can look spectacular; what’s not to like? Well, there is the part about how web browsers won’t do it without some sort of add-on, hence my Java applets.
What I don’t go into much is the Java part. Having the color cycling applets to point to allows me to claim some familiarity with Java, which is a useful thing for a technical writer these days. So there’s that. Moreover, Java is an Object-Oriented programming language. OOPLs used to be the flavor of the month; now they’re more like boilerplate. You have to claim familiarity in order to even interview for many jobs.
So let’s pause for a heavy sigh. (Sigh). I’ve complained many times about how the use of an ordinary word in a technical context can cause problems when the technical meaning differs significantly from ordinary usage. Jeez, does that apply to “object-oriented.”
Programming “objects” have nigh onto nothing to do with ordinary objects. They are programs! They do not have mass, weight, substance, color, physical dimensions, or persistence. Nor, for that matter, do they have anything to do with object code, the venerable term for a program that has been compiled into machine readable form.
What program “objects” have is “properties” and “methods.” For any old computer geezers such as myself, those translate to “data structures,” and “procedures.” But calling things by previously used names is so old-fashioned.
If that was all there was to it, then one might very well ask why bother, since there were already these perfectly reasonable programming structures called “sub-routines” and “modules.” Well sure, but there were a few new(ish) notions added to the mix: “inheritance” and “instantiation.” The former lets you create new “objects” based on old ones, with some modifications to the “encapsulated” data or the procedures that act on that data. The latter lets you fire off a bunch of similar program parts, each doing its own thing in the “multi-threaded environment” of the modern operating system.
See, this is just like taking your white hat and putting it into your matter duplicator, setting the dials to “blue” and “wings” so you have a new blue hat with wings. Then the blue hat can fly around and make fun of the poor wingless white hat.
That’s why they’re called “objects.” Because objects can do that sort of thing (snark).
Anyway, the idea was to use the object-oriented model to create re-usable program components that can be bolted together with minimal effort to create larger programs. This would have worked if it hadn’t been for those meddling kids and their stupid dog, I mean, if they had managed to get a variable typing system that was both consistent and comprehensible.
Unfortunately, the two major object-oriented languages, C++ and Java, based their variable typing conventions (as well as their syntax) on the C language, and that’s pretty much where the blue hat died and fluttered to the ground. C had so many exceptions and so much arcane weirdness in its variable typing that the whole thing was pretty much doomed from the start. It’s a simple fact that communication among “objects” can cause terrible headaches, because the variables they pass to each other get slippery.
Joke from the 1970s: C is Assembly Language in a clown suit.
Update to the 1990s: And C++ carries an Uzi.
Now realize, very little of this has anything to do with what someone is asking about when they ask you if you are “familiar with object-oriented programming principles.” What that translates to is, “Are you experienced with C++ and Java?”
I will say that the Object-Oriented project/marketing campaign succeeded brilliantly at making a lot more work for programmers. It also set the barriers to entry much higher and it resulted in the situation that programming now absolutely requires computerized programming tools. I wrote my Java applets more-or-less by hand, but I was hacking, just modifying previously written programs and sort of jamming them together. To do a similar project from scratch would have absolutely required a full bore Java programming tool set.
And it all would have been a lot easier to do in Pascal or even Fortran. But web browsers don’t support those, more’s the pity.

Objectification
When you get down to the nitty gritty, a common word like “object” can be a real poser (or should that be poseur?). Thus do I charge headlong into the sexual politics of the phrase “objectification of women.”
One very common interpretation of this phrase can be encapsulated in a similar utterance: “treating her as a piece of meat.” That, of course, also alludes to the phrase “piece of ass,” or just abbreviated to “piece.” Carried further, a woman becomes a collection of piece parts, breasts, legs, ass, abs, or sternocleidomastoids (to use an anatomical part that I find particularly pleasing).
The attachment of sexual desire to inanimate or impersonal objects is actually a fetish, though I’ll agree that “objectification” is easier to pronounce than “fetishization.” Both Freudian and Behavioral psychology have a lot to say about the role of the fetish in sex, with Freudians holding it as an example of the projection of sexual desire, while behaviorists suggest that operant conditioning is the key to understanding. I have no quarrel with either mechanism and I’m willing to believe that both apply.
The psychologist Nathaniel Branden, Ayn Rand’s lover/collaborator (before their nasty breakup) told a story of one of his patients, a full-fledged Lothario complex, who would speak of his conquests as “mere receptacles.” Branden suggested that he conduct a thought experiment. Suppose that one could construct a perfect female replica; this was pre-Stepford Wives, but that was the clear intent. Make a simulacrum of a woman out of plastic and rubber, totally lifelike, down to the genitalia, animated by motors and actuators. Would the Lothario find such a construct a desirable partner for sex?
“God, no!” was the reply.
Despite novelty “blowup dolls” (sold more often as gag gifts than as real sexual objects, I suspect), and other mechanisms, I believe that Branden’s patient’s response is typical. What is called “objectification” isn’t about reducing women to mere material objects; it is about using women as objects of fantasy, which is not the same thing at all.
In Peter O'Donnell's Modesty Blaise books, Modesty’s response to rape (and her history includes a number of such incidents) was to separate her consciousness from the event, thereby depriving the rapist of anything other than her physical presence. She refuses emotional connection, depriving the rapist of real domination. Within the context of the Blaise books, it is yet another indication of the primacy of the heroine’s will, her power over self. It also illustrates a thwarting of rape, and what that implies. Fetishization and the preference for a fantasy object is certainly depersonalizing insofar as it ignores the reality of the Other. In a sense, it denies the objective reality of someone else’s subjective experience. It is another pathological adherence to an internal model, a fixed idea about the external world.
Recognizing that we are dealing with the elevation of fantasy over reality in such cases also allows the realization that this is not a problem confined to men alone. Women crave the fantasy ideal as surely as do men; their fantasies tend to differ, however. It’s an open question as to what degree these differences are learned or innate. What is indisputable is that 1) they vary from individual to individual and 2) they are malleable.
The late comedian Richard Jeni had a bit where he suggested that the standard porn film is most men’s idea of a romantic film with all the boring parts left out. Compare and contrast that with the notion of the “chick flick,” which supposedly is nothing but the (for men) boring bits.
The clear implication is that romance is collaboration, and collaboration is hard, no matter what the circumstances. It’s hard to tell whether the fantasies of men and women are converging or diverging at this time; that’s a project that’s well beyond my own capabilities, and, for that matter, my interests. But simple observation and personal experience suggests that success is possible at the level of individuals, and that’s where my sympathies lie, in this as in so many other things.

Objective
After we came out of the church, we stood talking for some time together of Bishop Berkeley's ingenious sophistry to prove the nonexistence of matter, and that every thing in the universe is merely ideal. I observed, that though we are satisfied his doctrine is not true, it is impossible to refute it. I never shall forget the alacrity with which Johnson answered, striking his foot with mighty force against a large stone, till he rebounded from it -- "I refute it thus." -- Boswell’s The Life of Samuel Johnson
“Reality is that which, when you stop believing in it, doesn't go away.” -- Philip K. Dick
In Stranger in a Strange Land Jubal Harshaw, as a demonstration, asks one of his secretaries the color of a neighbor’s house. She answers “It’s white on this side.” The idea was that she was a “Fair Witness,” a person with special training who didn’t make assumptions about her observations, so her testimony was given special credence in a court of law.
Sometime when I was in grade school, living on Ironwood Drive in Donelson, Tennessee, I was witness to an unusual atmospheric phenomenon. There was a very low cloud overhead; I think it may have been a contrail cloud from the relatively nearby airport, because the cloud was long and narrow. It was otherwise clear, and near sunset.
We all know how vivid the sunset can be in the last few minutes of light. This cloud picked up the neon pink of the last rays of sun, but it was close. The whole neighborhood lit up with that light. My hair became red; my skin looked dark and sunburned. Our house glowed electric pink.
Our house was actually encased in white asbestos shingles. But for a few moments it was pink—at least on the side that I could see. Truth to tell, though, for me to say that it would have also looked pink on the sides I couldn’t see would have involved fewer assumptions than Heinlein’s “Fair Witness,” was making.
Is this a cheap shot at Heinlein’s expense? I hope not. I’ve seen climate researchers Spenser and Christy refer to their satellite microwave measurements as “direct observations” of atmospheric temperatures, when they most assuredly are not, given that there have been over half a dozen “corrections” to their estimates since they were first published. They are hardly alone is this sort of scientific conceit; I’ve heard such claims many times over the years, as well as researchers referring to various chemical rate parameters (often photolysis rates) as being derived from “first principles,” another nigh onto meaningless phrase used to cloak a welter of assumptions and models of reality.
“What is reality?” appears in a Firesign Theater record as part of a series of audience heckles, and that’s what it often feels like. What we have to work with is subjective experience, which is then denigrated to “mere” subjective experience. In Zen and the Art of Motorcycle Maintenance Pirsig has a nice long exposition on why words like “just,” “merely,” and “only” are out of place in any descriptions of objective reality, including science. They are indicators of a sneaky, subjective value judgment that someone is trying to slip into the mix. Chemistry isn’t merely very complicated physics. Chemistry is very complicated physics. The second sentence reads differently, doesn’t it?
We have a number of tried-and-true methods of “factualizing” subjective experience and most of them have to do with repeated observations, especially different kinds of observations. We believe in the “reality” of a rose because we can see it, touch it, smell it, taste it, and even hear it if it is moving through the air. Things that register on all the senses are commonly thought to be “more real” than something that can only be seen, such as a rainbow.
Objects also are given greater claim to objective reality if they persist, since persistence is one of the ways a single observer can make multiple observations. Objects made of matter have greater weight because they have weight, which persists, and can be felt.
Science takes everyday observations of reality and gathers them together into grand theoretical constructs, like Universal Gravitation, the Standard Model, and Evolution by Natural Selection. Scientific theories make sense of the world, allowing us to make predictions, or construct gizmos (in the largest sense) that give us power over the material and immaterial worlds. As Lester del Rey once said, “Mysticism has been around for millennia, science for only centuries. Science is ahead.”
The danger is in forgetting that our ideas about reality are themselves constructs. We believe that there is a reality, but no one has it on a leash, and no one speaks for it. The danger itself factualizes when someone projects their own subjective needs, fears, and desires upon that construct, making it yet another servant to the unconscious mind. We’re all guilty of that to some extent; paradoxically, it’s the ones who claim to most serve “reality” who are most likely to make their own ideas into yet another simulacrum of God. Then just crank up the dial to eleven, ‘cause it’s time for another episode of Monsters from the Id.

Poly
“Well!” said the woman in a huff. “Isn’t that just the way a man would think!”
________________________
Strictly speaking, polygamy is divided into two categories, polygyny and polyandry, the former being one male with multiple mates and the other being one female with multiple mates. In practice, polygyny is so seldom used as a label that it doesn’t even show up in my spell checker, and polygamy is generally taken to mean the multiple wives thing.
The predominance of polygyny over polyandry is pretty typical of mammals where there is substantial sexual dimorphism, i.e. where males are larger than females. In species where it’s the other way around (large females and small males), things aren’t quite so phalocentric, with the extreme cases being those insectoid suicide matings (bees, black widow spiders, etc.), that have served as the basis of many horror stories (or, contrariwise, female revenge fantasies, point-of-view being a factor in nomenclature).
Sociobiology and ethnology offer a lot of speculative theories on the nature of polygamy, most of them controversial, (well duh). It’s pretty easy to see how a shortage of males can lead to polygyny. Indeed, one hard fact in population demographics is that the birth rate in any given region depends on the number of women of child bearing age—period. It’s almost impossible to reduce the number of men to a level where it affects the number of children being born.
In the state of perpetual warfare that sometimes exists in some societies, a shortage of men is almost inevitable, and some sort of polygyny often results. Given long enough, this becomes institutionalized. It’s not necessary to invoke perpetual warfare, either; hunting large game is dangerous, and hunter/gatherer societies can easily develop male shortages and the whole “alpha male” structure, almost by accident.
A suggested countervailing influence in stone age societies is female infanticide. This is the dark underbelly of Eden, the crude population control measure that allowed the human population to remain stable for millennia. Some anthropologists have suggested that this sometimes led to polyandry, due to a shortage of females. It’s interesting to speculate about the future outcome of the gender imbalances that are being set up in some Asian countries as a result of pre-natal screening and selective abortion.
Female infanticide as a population control measure has been suggested as the origin of the form of institutionalized polyandry that exists in Tibet. One difficulty with this argument is that the custom is confined to a property owning class (which suggests that privation isn’t the primary origin), and that the woman’s spouses are fraternal, i.e. she marries the “family” as it were, and one brother is dominant, with the rest merely enjoying spousal privileges. That suggests that in this case, the custom is more akin to primogeniture, with the multiple husbands simply as insurance against infertility in the primary “alpha” male. It may be noted that this looks similar to the commonly noted phenomenon of infidelity on the part of the mates of the alpha males in various primate societies.
Substantial gender imbalances were the norm in the expansion of Europeans into the Americas, and history and folklore abounds in unconventional modes of co-habitation in the Old West. The Mormons dealt with their substantial gender imbalance in the early church with a “revelation” of God’s blessing for polygyny. By contrast, Wyoming Territory, responded to an extreme shortage of women by giving them voting rights in 1869, as an attempt to get more women to move to the territory.
A careful examination of social behavior in the Old West suggests that there is a form of polyandry that is seldom noted as such: prostitution. The legal system does its best to deny that the prostitute/client relationship is legitimate, as do practically all religious doctrines. But on any honest analysis suggests otherwise. What does a polyandrous relationship have that does not appear in prostitution? Certainly emotional relationships form; the client who wants to “make an honest woman of her” is so common as to be a stereotype. Children? Frequently children are the reason why women turn to prostitution. While it’s true that the anonymous sex of a street hooker doesn’t much look like marriage, it’s easy to find more domesticated arrangements upscale in the sex trade, while contrariwise, it’s not that difficult to find legal marriages that make a street hooker and her john look positively loving and healthy.
There’s no doubt that human relationships rapidly increase in complexity as the number of players increases. Same-sex monogamy will inevitably be even less complicated than the sort of opposite sex serial monogamy that has become normal in the modern world. By the same token, divorces in same sex marriages will certainly be at least as complicated as opposite sex divorces. Having both spouses “cheat” with the same individual is relatively uncommon in opposite sex couples, though it does happen, and, yes that’s yet another kind of gossip that will probably never appear in these essays.
But group arrangements, even when the group is so small as three, becomes so very complicated so very quickly that I doubt that they will ever be common enough for the law and mores to take much note of them. It should go without saying that such “outlaw” behavior is just the sort of thing that young people do as a way of testing limits, their own and others, just another set of behaviors that Seem Like a Good Idea At the Time.

Terminator
The State of the Union Address left a programming hole on the West Coast, which Fox filled with a re-run of the pilot of Terminator: The Sarah Connor Chronicles. I'd seen it already, but hey, it's still fan boy time.Okay, here's where I realized they had me. Near the beginning, when John Connor is starting his new high school, Cameron Phillips (yeah, and the FBI agent is name Ellison), the "helpful Terminator" sent back by John Connor in the future, is masquerading as a regular high school student, and engages John in some light conversation, just a pretty girl trying to make the new kid feel welcome. And I'm thinking, hey, she's doing a pretty good job of pretending to be just a normal pretty girl.
When they get you thinking that behaving normally is acting, you're have entered the Twilight Zone.
Of course, the main reason for that is Summer Glau, a most righteous battle babe. Formerly, in Joss Whedon's Firefly and Serenity she played River Tam, a genius girl who'd undergone "treatments" that made her psychic, drove her more than slightly insane, and left her with various triggers that could turn her into a lethal battle babe. So Glau is in danger of being type-cast, but realize that for an actress, being type-cast as a battle babe is actually a career extender. Glau can be playing tough sci-fi or cop roles for the next two or three decades if she so desires.

Glau also does most of her own martial arts stunts, by report, for the simple reason that she can. Indeed, she's far better at it than most, because she has dance training. There's a reason why they call it "martial arts choreography." The point where I went "whoa" in Serenity is in the she-beats-up-everyone-in-the-bar scene, where she kicks someone who has grabbed her from behind in the back of the head.

All of this presents a considerable problem for Lena Headey, who plays Sarah Connor. Even apart from all the damn milf jokes that are going to be running around, it's awfully easy for Glau to steal the spotlight, in a way that is reflected in the plot dynamics of the story they're following. Connor is, in every way, a tough, capable, hypercompetent human being. But she's still only human and she's fighting machines, plus, her main ally in this is also a machine, one that is stronger, faster, you name it. How can Sarah compete?
Moreover, the Terminator story lines just drip Oedipal conflict, and by the way, just how big a bastard is the future John Connor? In the first film, he sends his own father back in time to his certain death, something that must happen for John to be born in the first place, actually. His only real father figure that we've seen has been a killing machine (who also dies—kills himself, actually—while John watches). They seem to be trying to ring in another ersatz father figure in Charlie Dixon, but anyone can tell you that this can't turn out well. If he's really lucky, he'll get out alive.

So, okay, tough mother whose son is the only hope of the world. Check. Robot babe even tougher than the mother. Robot babe has been sent back from the future by the future son, so mother can't just get rid of her; besides, how? Robot babe is far too tough and smart for that.
Also, they're trying to destroy a new technology (Skynet) before it gets off the ground. This is Ted Kaczynski territory, so "every hand is against them." Also, they've already changed time—twice, and John's own origin is a damn time travel paradox, so the plot is bound to get as twisted as the mother-son relationship, or the son-babebot relationship, or just about any other thing that comes down the pike.
I do have one final riff that I'd like to see, but I'm sure it never will happen. In my version, Skynet was actually trying to prevent a nuclear war, and failed. Which drove it insane, so now it's trying to destroy humanity before humanity can destroy itself. Sure, it's a paradox, but hell, in this series, what isn't?
