    ...and are supposed to show that photons have mass, well they don't actually work.

    No surprise. No measurements have demonstrated that photons have mass--in fact, they have been shown to have, if any mass, only an extremely small amount of mass. If the science-fair prop were to show that, then a call from Stockholm would follow not long after.

    They rotate the wrong way as the heating effect caused by the solar radiation is vastly greater than the push from the photons :)

    This doesn't make any sense. What is the "heating effect" to which you refer?

    I understand that photons have momentum (or, classically, that a nonzero Poynting flux impinges on the vane surfaces), and that for optical frequencies roughly twice the momentum is imparted to the reflecting surface than the black surface by conservation of momentum. So one might guess that the vanes would rotate in the direction with the black faces moving forward. What is the mysterious "heating effect" that invalidates this argument?

    But it looks cool anyway.

    Well, we agree on this anyway.

    I'm sorry if this sounds a bit insensitive, but if your company has a policy that does not allow personal browsing, calling, and emailing with their equipment, then you should not make these calls, browse the internet, etc. on their time. If you lose your job as a result of violating these policies, then you are not in a very sympathetic position.

    If you can't run your errands without violating policy, then your errands simply don't get run. In principle you could always (a) get a cell-phone to make your personal calls, (b) go to a public library over your lunch hour to do your web browsing, (c) take a half day of vacation every time you have to stand in line at the DMV to get your license renewed.

    That being said, most places will allow limited personal use of their equipment since it just makes good business sense to do this rather than be draconian in enforcing the policies. Probably the safest thing to do is get some clarification from your supervisor on what the policies are regarding personal use of the corporation's equipment and facilities.

    I'm not sure what you mean by "balance" here, or by "sensationalism." Ostensibly the author could have written "While company X reads its employee email, company Y doesn't." This would seem to detract from the point of the article, which is to demonstrate via a case study what the current state of people's rights are regarding the internet and email. Law in the U.S. relies heavily on prior judgments; the outcome of one case may affect the outcome of all similar, subsequent cases. As such, the cases identified in the article are entirely relevant to the point being made.

    Frankly, I find the whole notion that every piece of journalism must have "balance" to be silly, as it often gives undeserved weight to the fringe and this practice can reduce the credibility of the story rather than add to it. Would you require a journalist reporting on, say, the Holocaust to find a kind SS officer to balance the story of bulldozers and piles of bodies with a commentary on the merits of the "Final Solution?" Of course the privacy issue is far less tragic than the Holocaust, however the point is the same: "balance," while it is lauded in journalism schools, is not appropriate in some stories.

    One of my classmates in physics graduate school received her engineering undergraduate degree from a top-10 engineering university. While attending this university she experienced one of the most egregious instances of gender discrimination I've heard of to date. This was in 1990, mind you, which is far closer to 2000 than 1950:

    After taking a midterm examination in her engineering course, she was surprised to find a "Drop Form" attached to her exam when it was turned back to her. Apparently she was not alone: all six of the women in her class of 250 students had drop forms attached to their examinations. When questioned on the matter, her engineering professor stated that he didn't believe women could be good engineers so he was encouraging them to drop his course and find another major.

    She promptly changed her first name to "James" to avoid further discrimination of this kind. The professor, while reprimanded by his department and dean, is still teaching at the same university, and I doubt his feelings towards female engineers has changed much. I believe it is safe to say that gender discrimination is alive and well today among some leading engineering universities.

  8. What good is reflection? (devil's advocate) on Are Computers in Classrooms Bad for Learning · · Score: 1

    An excerpt from the article:

    ...but education is not about impressive technology. It's about acquiring knowledge and learning to think, in which case libraries, pens, and paper are the clear winner, hands down.

    Allow me, if you will, to play devil's advocate and propose that "study, reflection, and observation" are no longer vital skills; pattern recognition and the ability to assimilate at a superficial level preexisting knowledge seem to have replaced cognition as the key element of success. Except for a lucky few who do genuine creative work, for most in society it matters not whether one can come up with a fresh perspective on a given problem, but rather whether the problem can be recognized as being similar to another that has already been solved. We live in a society of shortcuts and heuristics; whoever has learned the most (and the most useful) shortcuts and heuristics is bound to be the most successful.

    I'm not arguing that being able to reason is no longer useful, as it most certainly is of value in some circumstances, however it is secondary to, say, the ability to learn the latest software package after being shown how to perform the necessary operations. We want people who can follow procedure, who respond most favorably to "bulletized" instructions, people who feel restless and seek quick solutions after thoughts occupy their minds for more than fifteen seconds. Spending any longer on a problem is "wasting time," time that would be better spent consulting an expert for the answer. Unlike the past, described so eloquently by Glieck, experts are cheap--they are just a few mouse clicks away--so why not use them?

    Teaching children at an early age to follow instructions without questioning them and to instinctively look to an expert/web browser for expertise are possibly the most valuable job skills we can give them.

    I'm old enough to give the government a large chunk out of my paycheck, but I'm not old enough to vote.

    Youths are protected under law more than adults are as well. E.g. contract law is different for minors than for adults. Similarly, the criminal justice system is different for minors than adults. The voting age has to be set somewhere, and 18 is as reasonable a place as any. I have been paying taxes since birth, however I think it would be folly to suggest that I was a qualified voter when I was, say, two years old. If we moved the voting age to 16, then what about bright 15-year-olds? If we move it to 15, what about those precocious 14-yr-olds?...

    So apparently "no taxation without representation" no longer applies?

    It never applied in the first place. While it served as a rallying cry during the early days of the U.S. revolution, it was never anything more than political rhetoric. O that my tax burden could be as light as it was during the days of the so-called "Intolerable Acts"....

    Did all these "idiots" become that way after they turned 18, you think? If not, then if we lowered the voting age to 16 (but why stop there--how about 12?) wouldn't we have even more idiots voting?

    If you think the system is unfair now, think of how it was for those who were drafted in some of our earlier wars in the U.S. They were old enough to go off and die for their country, however they were too young (under age 21) to vote for those who put them in harm's way to begin with. At least you can cast your vote in a couple of years rather than five years down the road.

    Many ideas for election-screening have been considered: Some have argued for civics examinations of voters to prove their worthiness. However, there seems to be no fair way of doing this that doesn't offend one group or another. Some have argued that one should pay money for the right to vote, the idea being that whoever pays for the right to vote will value it more. This has the side-affect, however, that it discriminates against those with limited means or those whose racial groups encounter higher poll-taxes. Heinlein's "Starship Troopers" (the book, not the movie) had an interesting, if somewhat controversial, take--in order to vote one must first serve a tour of active duty in the military. A curious proposition indeed. The architects of the U.S. Constitution determined that just being a white, male, U.S. citizen was enough to qualify a voter. Again, this is an imperfect scheme since the percentage of women and minorities who are qualified to vote is significantly higher than that of qualified 16-yr olds. While the present system is not perfect, and it empowers some with the vote who undoubtedly do not have the best interests of the nation at heart, at least it has a modicum of fairness in its accessibility.

    Incidentally, when you are too young to vote you can still participate in the political process by doing volunteer work for the candidates, parties, and referendums you believe in. In doing so you probably will have more than one vote's impact on the election outcome.

Like you, I neither condone the activities of the U.S. or U.K. governments, nor do I believe that information like this should be kept from the people who make decisions, if even the decision on whom to vote for. I am merely pointing out that for whatever reason this information was classified Secret, which means that only a restricted body of individuals may access the information, and the information may not be shared among those who lack sufficient clearance.

While we may debate whether the material was classified correctly, whether the public had a right to know this information, or even whether any organization should have the right to hide such information from the public, while it holds a Secret classification it needs to be protected in accordance with this classification level.
