    Chernobyl and Fukishama have now both shown that nuclear incidents are ALWAYS worse then estimated and even worse then admitted to afterwards by the nuclear lobby. You can build again on a flood plain, but radiated soil will be unusable for decades.

    Ecologically, the Chernobyl meltdown was a mixed bag. Some species were harmed, but many species benefited from it. The beneficial effects came because humans left the area. Dense human habitation is the worst possible thing that can happen to any ecosystem.

    The Supreme Court seems to think that their rulings supersede what's actually written in the Constitution. They are wrong. When they cannot enforce the Constitution as written, they endanger the legitimacy of our government.

    But of course different people have different opinions about the meaning of "what's actually written in the Constitution." The first amendment says: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." There is nothing "actually written" in the constitution about sleeping in a public park. If you equate sleeping in a park to "assembl[y]," you're stretching the meaning of what was "actually written." In this particular case, the Supreme Court *is* reading it as "actually written," and you're not.

  6. I'm willing to sell my nuclear knowledge. on Identifying Nuclear Scientists Willing To Sell Their Knowledge · · Score: 1

When I saw the title, "Identifying Nuclear Scientists Willing To Sell Their Knowledge," I thought, sure that's me. I'm willing to sell my nuclear knowledge. In fact, I do sell my nuclear knowledge. I teach physics at a college. That's what the taxpayers pay me to do. Is there some reason why I would not want to do my job properly in some very large subfield of physics such as nuclear physics? Of course not. It happens to be my specialty, so I'll probably do a better job teaching it than any other topic.

This goes a long way toward explaining why "About 1% of entrepreneurs who received venture capital in the first half of last year are black,[...]" This applies to any field where you're talking about a group being underrepresented; you have to look at the talent pool. If the group is underrepresented in the talent pool, then it's too late to fix the problem. They're simply going to be underrepresented in the field.

    And why is it necessarily a problem if a particular group is underrepresented or overrepresented in a particular field? There are a lot of Jewish doctors out there. Is that bad?

For a nation-state such as, say, Iran, that is contemplating a nuclear first strike against the US, four submarine-based missiles are plenty of deterrent. That's enough to destroy Tehran, Mashhad, Isfahan, and Tabriz. That would kill 20 million Iranians, and eliminate the country's political and economic structures.

Iran has no missile defense capable of stopping incoming US missiles, and neither does Russia or any other country in the world.

    We have one of the longest constitutions in the world, and one of the reasons is that initiatives are often written as constitutional amendments. A particular problem is all the constitutional stuff that requires that a certain amount of tax revenue be given to certain purposes, combined with other constitutional restrictions that make it basically impossible to raise taxes. The result is that it's essentially a constitutional impossibility to balance the budget.

    All of our direct democracy in this state was originally intended to allow the people to fight back against railroad barons. Now guess where all the initiatives on the ballot come from? Yep, they're funded by rich people and big corporations, who can afford to pay signature gatherers $1 a signature to get on the ballot, and who can then afford TV ads to convince people to vote for their initiatives.

    I teach physics at a community college in California, so I'm one of the gatekeepers who washes out STEM majors. It's my job to do that. Society can't afford to have anesthesiologists who can't convert grams to milligrams, or civil engineers who can't add force vectors. A lot of the people who don't succeed in my class are very nice, sincere people. It's just that their talent lies somewhere else than in math and science. The sooner they find that out, the sooner they can find a more appropriate major.

    In addition to the good but untalented students described above, there are many who don't succeed for other reasons. There's a book called Academically Adrift, by Arum and Roksa, which is summarized here: http://www.newyorker.com/arts/critics/atlarge/2011/06/06/110606crat_atlarge_menand . One of their findings is that the average time studying has dropped dramatically in the last 50 years. The average number of hours per week was 25 in 1961, 20 in 1981, and 13 in 2003. This drop is still present when you control for the fact that different people go to college now than in 1961.

    Another finding, which has been replicated by others, is that students' critical thinking and writing skills show extremely small improvements over the course of a college education. The improvements are so small that they are undetectable on the individual level, and still quite small even when you average over a large number of students. Well, maybe we shouldn't expect critical thinking and writing skills to increase so much. Maybe they're innate talents, or maybe they're fixed at an earlier age. But if you get a degree in a field like English or philosophy, essentially the only thing the school *claims* you're getting out of it is critical thinking and writing skills. And greater improvement in these areas is found to be correlated with faculty's high expectations, high standards, and approachability; the fact that there is so little improvement on average suggests that the lack of improvement is caused by faculty's low expectations, low standards, and lack of approachability. For example, a third of college students report that by the time they graduate, they have *never* taken a course that assigned more than 40 pages of reading per week.

    The thing is, in STEM, you can't just BS your way through your term paper. There are right and wrong answers. We can't just lower standards the way the humanities have done.

    A lot of students are urged by their parents to go into STEM because they think the kids will make a lot of money. Once the kids are in college, they often realize that if their only goal is to make a lot of money, they are much better off getting an undergraduate degree in business. Unless you're in particular subfields such as finance, business is by far the easiest major.

In the early 1980's, there was the first wave of mass-marketed personal computers: Apple II, TRS-80, etc. Software houses often sold games, for example, on 5" floppies in a format designed to make it possible to play the game, but to make it hard to copy the disk using the OS's standard tools. Computer users voted against copy protection with their feet. For one thing, there was no other backup format besides those unreliable 5" floppies, so if you couldn't copy it to another floppy, you were basically just paying to be able to run the software for as many years as the floppy was readable. Software houses started to realize how much users hated copy protection, so they stopped doing it.
