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.

zrejme bude pravdepodobnost selhani desticky nekde okolo 1:100000... *evil grin*

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.

Prave ctu Diamantovej vek od Neala Stephensona. Nanotechnologicky inzenyri maj nad svejma hlavama vymalovanou fresku na ktery je znazornenej Dick. Holt nano Buh, jj. :))

MIKEE: A ja diky Makosharkovi zjistil, ze se ten Penrose da celkem za solidni cenu objednat z Neoluxoru. Tak se tesim. :)

WENCA: jo jo, to s tim pul rokem je pomerne realny ... dejiny americkeho naroda citajici asi 800 stran jsem louskal po kouskach aspon tri mesice, asi i o neco vic :]

MIKEE: [ MAKOSHARK @ Cteci nebeletristicke auditko - faktograficke, vedecke, ale jenom ne beletrii :-) ]

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 :)

MOYYO: jo, to bez diskuze :] .. resp. nechat to ulezet .. a pak se k tomu vratit :]

MIKEE: ta bolestiva stranka je, ze obcas se musis zamejslet treba rok nebo dva, nez to ocenis ;)

MOYYO: jo, to asi vetsinu lidi co nemaji v hlave misto mozku slamu ... to je v zasade to co feynman rika tim "But you gotta stop and think about it" .. nestaci o tom jen vedet .. az kdyz se nad tim zamyslis tak skutecne ocenis tu krasu :]

hehe, s tim bazenem me to napadlo taky :)

Je to fakt dabel. :))

SARNEGARTH: buu, spojeni se serverem nebylo navazano... muzes to soupnout treba na leteckou postu nebo tak neco? diky

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").

Dneska mi konecne dosla tato uzasna knizka.

Zatim jsem ji jenom zbezne prolistoval a vypada fakt moc dobre. V kazdy kapitole jsou strankovy medailonky o nejakym fyzikovi, v kterych jsou dost zajimavy bulvarni informace (jak si Gell-Mann udelal brutalni prdel z Dicka, jak Gell-Mann probihal sklonenou hlavou volierou, atd. :)).

Jeste se tu o ty knizce asi zminim. :)
