  1. Re:Newton's on Using Neutrons To Precisely Test Newton's Law of Gravity · · Score: 1

    That's a bit of an oversimplification of relativity. Some simple, highly idealized calculations can be done by just replacing an input with a modified version of it, or modifying the result of a Newtonian calculation. But, calculations involving significant gravity are far more complex. I would agree with you if we were talking about special relativity instead of general, or if the calculations were kept simple.

  2. Re:Newton's on Using Neutrons To Precisely Test Newton's Law of Gravity · · Score: 1

    There's a big difference between today's conception of Newtonian mechanics and (what I presume was) the original conception of it. Today, we call it an approximation; originally, it was perfectly precise. The original idea has been falsified, but the newer version with supplemental error bounds is alive and well. The add on analogy is a little bit of a stretch, but I don't think it's awful. Loading the GR module would be akin to adding routines that could predict the impact of a black hole meandering through our solar system, for instance, in addition to improving the accuracy of the Newton module's routines. It entirely replaces the Newton module, which is where the stretch comes in. Quantum fits pretty well in the analogy, though.

  3. Re:Why? on Armenia Makes Chess Compulsory In Schools · · Score: 1

    I very much agree about the usefulness of teaching a "logical fallacies" class. I'd love to hear about one aimed at standard high schoolers. Something in between a very basic first order logic course and dissecting politician's speeches could be extremely useful. Lewis Carroll wrote a book I've glanced through that's close to what I mean. (In addition to being an author, he was a logician.) It was basically formal logic aimed at young children, which is close to the same idea. I think it would be drastically more useful than studying conic sections (why they're so emphasized I'll never know; they really don't come up enough in later math to justify their placement in curricula, IMO. For the mathematically inclined, they're also easy to understand quickly).

    I don't like calling calculus "advanced math" because nearly every technical discipline makes heavy use of its more basic features, so it's been dumbed down, a lot. It's more of a gateway to real advanced math that also happens to be incredibly useful, both to other areas of math and other disciplines. Certainly calculus can "become" advanced; for instance the differential form generalizations of Stokes' theorem are advanced. But that's not usually what people mean when they say "calculus". They mean the product, quotient, and power rules; derivatives and integrals of standard special functions; various integration tricks; a tiny bit of physics relating derivatives to velocity and acceleration; etc. They do not mean the playthings of mathematicians and a few poor souls like theoretical physicists who require advanced math to describe their theories.

    Interesting. Poker has some seedier characteristics I don't think would fit well in schools--like how it encourages manipulation and gambling. It would improve probability skills, though. I'm sure if I had had to play poker regularly in school I would have computed various probabilities and maybe learned to count cards, since I'm both competitive and good at math. I can see myself learning/deriving basic combinatorics and probability in that case. I also might have learned to read people better, earlier.

  7. Re:Chess in an educational setting on Armenia Makes Chess Compulsory In Schools · · Score: 1

    There's no reason the person who excels in "chess lectures" can't play the game because they enjoy it as well. It's a happy coincidence for some people that their interests coincide with their studies. Having a strong international presence in high level chess would probably only take half a dozen or so really good players, so even if the overlap is rare that's fine.

  8. Re:Personal Experience on Armenia Makes Chess Compulsory In Schools · · Score: 1

    I played chess with my dad when I was younger but my skills plateaued when I started to regularly beat him and he stopped wanting to play. I've played maybe a half dozen games in the last 8 years. I'm vaguely decent, but it might have been nice to have compulsory, regular games. I never got to the point of thinking more than a few moves ahead, or predicting my opponent more than a move or two ahead.

    Maybe I missed it, but why do you say "This article clearly demonstrates what's wrong with America's science reporting"? The author of TFA, Gavin Atkins, appears to be Australian. The hosting site, Asian Correspondent, doesn't appear to be related to American news. I agree with the general statement that science reporting is more often than not just terrible, but I don't see how America's science reporting enters in here. In any case, thanks for the thoughtful post!

  19. Re:Really, I thought the question is... on Are Graphical Calculators Pointless? · · Score: 1

    Most of my college tests were take-home. There was a strong "do the right thing" culture there, and nobody I knew cheated, to my knowledge. For some of my CS tests, we weren't allowed to have a computer on while taking the test. People grumbled about it, since then they couldn't listen to music (depending on their setup)--if the test required the computer to be off, it would be off. I'm pretty sure my college was strange in this regard. It was both prestigious and "nice", which was a big reason why I picked it.

    Certainly some people did cheat. Every semester or two a few people would get disciplined for it. None of those cases were like the one you describe, using some online answer service or forums. They were often technicalities, or relatively minor things like taking more time than allotted. They were often also self-reported, though not always. Overall the convenience and respect of take-home tests was worth it there. A similar setup at my high school would have been nuts, though, since cheating would have been incredibly rampant.

    Well, he did say "the proof of the quadratic formula". I guess the proof could be entered in a text note of some kind. The proof is really quite brief, though: complete the square. I could understand not remembering how to solve a cubic or quartic. They typically use substitutions pulled out of the aether. I have a book that derives a key chunk of the usual method for solving quartics geometrically, but it runs through some basic projective and algebraic geometry and linear algebra--it's definitely not shorter than writing a sequence of magical substitutions, even if it's (arguably...) more intuitive.

  21. Re:Nope on Could You Pass Harvard's Entrance Exam From 1869? · · Score: 1

    I'm fine with the majority of people getting focused trade-oriented higher education. I also have a liberal arts education and am on the path of a future professor/researcher. To most people, I don't think a "well rounded" education is helpful enough to justify the cost in time and money. For instance, I'm thrilled whenever someone wants to learn calculus, but it's just not useful to most people in most areas of society. In a more ideal world, perhaps everyone could recite Dante in the original Italian and solve differential equations, but realistically society is better off *not* wasting productive years forcing everyone to slog through coursework they get little out of.

    I think a broad education has its merits, and that some sizable-but-sub-majority fraction of society should get one. I also think a core of hard science (physics, chemistry, math, etc.) should be the basis of a well-rounded education instead of the current art/music/literature/etc. core.

    I had watched TAS a year or so ago. There were two episodes I liked, but most of them I had a hard time sitting through. I remember being repeatedly glad that they were only ~22 minutes, and that there were only a couple dozen or so of them. The Wikipedia article is much kinder than I expected. It was also a children's show, so watching it as an adult is kind of unfair. Maybe if I had watched it years ago I wouldn't have disliked it so much. The animation was often cheap, the plots didn't fit very well into the short running time, and they were often silly (even for Star Trek). The child me wouldn't have noticed any of this, though.

    For the record, I like TOS, and every other Star Trek series besides TAS. I really only watched TAS for completion, seeing as I had seen every other episode of every other series.

    I mean that it's not clear to me that a Bernoulli RV saying "weird" or "not weird" was used, as opposed to some continuous measure of "weirdness". For instance, if 249 cases were only slightly "weird", it might be completely unremarkable. Your quote didn't support the expectation of 1 weird result in 10,000, though perhaps the paper does support your 0.6 number. My second sentence wasn't sarcastic, it's just missing an "n't".
