They work hard. Americans > don't want to work hard, I disagree. Americans work very hard. We just work very hard at things other than mathematics. The reason that the Chinese are so good at math is because they are disciplined, not because they work hard. There's a significant difference. The Chinese are more disciplined because they live in communist country, and that is simply the nature of communism. Capitalism has more of a free spirit, more of a creative side, but it is quite lacking in discipline. The competitiveness of capitalism, however, can more than make up for this lack of discipline. Capitalism is generally better able to regulate resources. The problem is that cultural cohesion in America (Blacks, Latinos, Asians, WASPs, etc...) creates segregation and makes the allocation of resources in education system inefficient. America is like a Ferrari with half its spark plugs missing, and China is brand new Ford Model-T modded for racing. If we would just fix our broken system, China would be eating our educational and technological dust. > out-source their economy to Asia and open their > boarders for hard working > workers.

When will that start? The real grade inflation in our area began in the private schools and colleges.

the three Rs merely create learning disorders, since they are essentially cognate to the fuller acquisition of language (around puberty, ~5th grade). so, teach the quadrivium, hands-on, no writing!... (that is to say, *mathematica*, not Mathematica (TM) .-) and, I say this, as a product of the New Math in the public schools: set theory in 3rd grade! (NB, Harry Potter schools in England, used to be called Public Schools, because of their institutional affiliation -- not, "no reason, we're just British," as all of the Subjscts seems to say .-) > When will that start? The real grade inflation in our area began in > the private schools and colleges. thus: like I always say, "global" warming is almost entirely a) computerized simulacra, and b) very selective reporting (and c) the latter is based upon "practically nil" historical data for the vast majority of glaciers e.g.). thus: I've written to Dudley about one of the "proofs" in his book, in the Fermatistes Chapter; he replied quite cordially. anyway, it was obvious from his write-up, that he did not actually read the small "vanity press" book that the dood put out, but just jumped to the penintimate chapter & couldn't follow it ... but, neither could I, and I read the whole thing, and it's really a humorous book, and the guy was a student of Prandtl at Gottingen. (Dudley seemed to agree, that that was his own MO .-) anyway, the dood thought that he'd found the proof of Fermat; that is to say, his method. it was all, quite elementary, using Ore's _Numbertheory and Its History_, and only ommited stuff that was supposedly in a monograph on trig series by Vinogradov (I usually lose the track, when ever "big Oh" comes over .-) there was one other "proof" in _Cranks_, that seemed somewhat plausible, two. thus: you can get rid of phase-space ("spacetime") with "movies" (or flip-books), becuase it is totally useless in a non-mathematical-formalist sense, "visualization" e.g. -- death to the lightcones!... and, it gives you an extra spatial dimension to play with. as for the idea of using two quaternions for "in & out," I don't really see, why it'd help, since you can use the same quaternion coordination for both, unless there's some dimensional analysis that needs a pair of them. (see Lanczos' _Variational Mechanics_, Dover Publ., for his treatment of SR -- good luck .-) thus: the second root of one half is just the reciprocal of the second root of two -- often obfuscated as the second root of two, divided by two -- but the rest is indeed totally obscure or ridiculous. since Fermat made no mistakes, at all, including in withdrawing his assertion about the Fermat primes (letter to Frenicle), all -- as I've popsted in this item, plenty -- of the evidence suggests that the "miracle" was just a key to his ne'er-revealed method, and one of his very first proofs. (I wonder, if Gauss was attracted to the problem of constructbility, after reading of the primes.) thus: so, you applied Coriolis' Force to General Relativity, and **** happened? > read more » --Light: A History! http://wlym.TAKEtheGOOGOLout.com |
