    There is a reason we built the ISS. Because aerospace contractors found a way to convince Reagan & Congress that it was important to fund the ISS to keep America from "falling behind." Falling behind in what, you ask? In space technology! Why is it important to lead in space technology?

Heisenberg, possibly as brilliant (though with hardly the experimental acumen), working in Nazi Germany, got nowhere. Likewise for von Braun--Nazi Germany had him developing penny-ante weapons, the U.S. had him boost people to the moon. (I suppose he helped the U.S. develop ICBMs, but hey, that's technology, too.) Even Einstein died an American.

    If the U.S. is still the destination of choice for the best and brightest foreign-born minds, that's going to pay off BIG in the long run. The only challenge I see is Chinese-born professionals starting to feel that China offers enough freedom to make staying there pay off more than coming to the U.S. In order to do that, China has to focus on maintaining its own internal stability, probably liberalize its political system, and will have to take a very calm approach to international relations. That helps the U.S., too, so the downside of being the second-largest national economy won't be so bad.

    The problem with your model is that the studios really can't be sure whether a movie will make a killing until it is released. There is a huge element of risk in what are one-time artistic efforts. Consumers can't pay in advance for a movie to be made.

    Something like English Patient, for instance, could very easily have vanished without a trace.

    There are all sorts of reasons for inexpensive, yet ultimately unprofitable films to be made. One of them is the chance that one out of fifty of these might become a wild success. Another is that directors/actors want to work on more creative, challenging projects, and the studios pay for it, in order to keep them around for the less creative but more marketable stuff they churn out to make a profit. These are reasonable choices made by rational profit-seeking companies.

    "Engineering" refers to starting with a goal (desired functionality) and arranging materials in a way (determined by a possibly involved design process) that reaches that goal (by delivering a finished product that works).

    "Reverse Engineering" is the exact opposite: one has a finished product that does something, or at least would if it were in proper working order. (Did you break it?) There might be some documentation. One might have some idea of the goal, perhaps only a vague one. (E.g., an automaker might reverse engineer a competitor's automobile, which has an obvious goal. For a Windows virus, you have a vague idea that the program is supposed to cause damage and/or replicate itself.) The missing part is insight into the design process that happened. Figuring out that design process (by whatever means) is the goal of "reverse engineering."

    Why do you want to know about the design? You might discover the secret behind some unique functionality. You might expose some flaw or weakness. You might be able to reconstruct enough of the internal protocols to be able to develop compatible products. (E.g. understand enough about IBM's PC BIOS to document its behavior well enough for a programming team to construct a compatible BIOS without simply duplicating the ROM contents, to break into the market for making PC clones in the 1980s.) You might just enjoy tearing things apart.

    It is not strictly true that all graphics in TeX are EPS. TeX/LaTeX do not know anything about graphics files except for "graphics" made by putting TeX primitives on the page.

    What TeX/LaTeX can do for other types of graphics is include "special" commands which are picked up by the driver that processes TeX's .dvi output. The most common driver is dvips, which accepts special commands which refer to EPS graphics, which dvips can then incorporate in the PostScript output. By using different drivers, such as PDFTeX, one can incorporate other graphics types, such as JPEG, directly.

    BibTeX shouldn't be that painful, although you need to be pretty in tune with LaTeX customs to really feel comfortable with it. (That is, once you understand how LaTeX does tables of contents, etc., you can understand how BiBTeX fits into the workflow.) The bonus is that many source of citation information can give it to you in BiBTeX format, so you can quickly build up your database of sources you commonly cite.

    My experience (like most people) was learning LaTeX & BiBTeX for my thesis, and I feel that the relatively small effort paid off because I avoided fighting Word. Sometimes you need to debug LaTeX (forget a brace), but it's like learning any other programming language: there are fewer than a dozen common ways for LaTeX to fail, and you learn how to find and fix the problems pretty soon. Then, the only thing left to learn is the final polishing of formula appearances, punctuation, etc., which only needs to happen if you really want things to look nice.

    The problem with Word is that there are a lot of very strange behaviors that aren't easy to fix, especially as documents get large. There is a lot of hidden markup that eventually gets bunged up, and then no amount of fiddling seems to make it work again. And no amount of fiddling will make Word's formulas look like anything but crap. I've never had Emacs or LaTeX crash on me and cause me to lose work.

I understand the kind of stuff that condensed matter theorists do: making expansions, various kinds of approximations, mixed in with quantum and statistical mechanics; and I know when they think they are finished. I guess one problem is I just don't understand topological deduction at all.)

    Anyhow, the point made in the article is that not everyone making string theory arguments has as much of a grasp of the necessary mathematics as they should, and referees don't have the time to check all their work as rigorously as one might like. That means that sloppy, useless, impenetrable stuff can still get through the system.

    My take as an outsider is that these people probably don't have any truly publishable ideas, just confusing ones. If their careers are "ruined" it's probably because their careers shouldn't have been leading anywhere.

    To be more complete, however, an overelaborated theory usually is superseded by another theory that is aesthetically superior, and can be scientifically fruitful, even if the initial evidence is somewhat lacking.

    Rarely does a overelaborated theory get discarded without some other theory to take its place. That's how this process can keep moving in a direction that seems to be forward.

    It's also important to emphasize that theories get overelaborated because of experimental measurements that meet relatively high standards of technical excellence. Ptolemy had to have cycles to *accurately* account for observed planetary motion. That's an important thing missing from the parallel phenomenon in art. Planetary motion wasn't *settled* until impressive observations were made by Brahe and others, for Kepler to use. (Copernicus is an interesting case: the circular orbits are less accurate than Ptolemaic systems. That one could favor a less-accurate theory is the human part, but the less-accurate theory had to be made more accurate to finally win, because people didn't disbelieve their hard data.

    In principle, you could bid with me for the privilege of making my air dirtier in exchange for money. If I decided I wanted pristine air, the bid would have to be high, and there would be few polluters who could afford to pollute. As long as I voluntarily accepted the bid, and were fully informed as to the effects of the pollution, I would have no reason to complain. I gave up my clean air for good money. Perhaps even enough to buy an air filter that would remove the pollution with some left over.

    The problem is that we don't have the power to control the air we breathe, except through governmental regulation. Therefore, one alternative is to tax activities that cause pollution. The government collects the money, instead of the individuals, but in principle, it has a similar effect on polluters. Presumably, it would be even more effective if a market existed to determine the price of pollution, with producers having to bid for the right to pollute, instead of having a fixed, somewhat arbitrary tax rate.
