The physicist Richard Feynman demonstrated his abilities at mental calculation when, during a trip to Brazil, he was challenged to a calculating contest against an experienced abacist. The abacist happened to challenge Feynman to compute the cube root of 1729.03; since Feynman knew that 1729 was equal to 123+1, he was able to give an accurate value for its cube root mentally using interpolation techniques (specifically, binomial expansion). The abacist had to solve the problem by a more laborious algorithmic method, and lost the competition to Feynman.

co mi to jenom pripomina? ;))
V NASA se dlouho diskutovalo o třech uhlíkových izolačních destičkách, u nichž hrozí koroze. Inženýři chtěli misi odložit a destičky pro jistotu znovu otestovat, vedení ale nakonec rozhodlo, že riziko je "přijatelné". Oprava by prý trvala měsíce a stejně by byla zbytečná.

mi tady porad lezi Road to Reality od Rogera Penrose .. a porad se ne a ne k tomu dostat .. to je nicmene docela solidni bychle, takze je takova intimidating :]

napr:
sem ted docet griffiths - intro to std model. krasna, jednoducha, polopaticka a vstrebatelna knizka.
jako pokracovani sem vzal knizku od weinberga - quantum theory of fields a utopil se v tom na prvnich 20ti strankach :)

kdyz uz o gell-mannovi, narazil sem na takovej hezkej spek o ignorantstvi ;)
Gell-Mann himself, by his own admission,
should have predicted the omega minus a year or two before he did, but
his own arrogance about pure mathematics and, yes, Lie Groups, prevented
him from asking about them. Essentially he was trying to discover the
eight-dimensional irreducible representation of the group SU(3) by
himself by playing with matrices, but failed (these groups had long ago
been classified by mathematicians like Eli Cartan). His excuse was that
he was in Paris at the time, and in a constant state of
semi-drunkenness. It was only after he got back to California, and
unfermented fruit juice, that he thought to ask a mathematician...
He could have known about Lie groups earlier, since I believe he was
present at Guilio Racah's famous lectures on group theory and
spectroscopy at the Institute for Advanced Study, Princeton. I think
his excuse for this was he couldn't understand's Racah's "Yiddish
accent." (Racah, an Italian Jew, who didn't know Yiddish any more than
Gell-Man, was the head of the Hebrew University's department of
physics.)
So we have the intolerance chain: physicists are intolerant of pure
mathematicians who are intolerant of f.o.m. And philosophy often is at
the receiving end also (though almost invariably it's "the philosophy I
don't like" which is referred to by the word "philosophy").
