WENCA: Ale pockej, ono to tak trosku i je!
Kdyz definujes (asi ne uplne rigorozne, nejsem matik) realny cisla tak te stejne zajimaji jenom ty vyznamny jako neutralni prvek vuci scitani a nasobeni apod. Na zavedeni prirozenejch cisel a scitani ti v podstate staci jenom jednicka. V definici sin(), cos() potom oznacis urcity cislo znackou PI a exponenciela ti urci vztahy, protoze zjistis, ze exp(iw)=cos(w)+i.sin(w)...
Je to ohromne silny tvrzeni.

Mozna vic o tom tady: [ mame radi matematiku ]

KOJA: Nam ve skole tvrdili, ze v cisle Pi je zakodovano vsechno. :)

KOJA: Jo, ja tomu verim. :)

WENCA: Nekteri lide dokonce tvrdi, ze techto pet konstant ti staci na vsechno :)))

Euler's identity e^iΠ + 1 = 0 has been called "the most remarkable formula in mathematics" by Richard Feynman.

WENCA: No musim rict, ze posledni tyden jsem ho dokonce hltal. Zaplat panbuh za jeho prednasky!

Ja toho kluka proste zeru. :)

Feynmanovy diagramy opet na scene. Sice asi jen 5s, ale prednaska je to zajimava. :)

KOJA: no tak to je maso, India? korea? singapore? Israel? amerika az pata? nechapu nic:>

KOJA: Heeeej, tak to je parada!

Jsme druhy!

MELOUN: No ja v bode 3. :)

WENCA: hehe..dost dobry, vzdycky se zaseknu ve fazi 2

Physics is like sex. Sure, it may give some practical results, but that's not why we do it.
Physics is to math what sex is to masturbation.

:-D

MELOUN: I don't have to know an answer. I don't feel frightened by not knowing things; by being lost in a mysterious universe without any purpose— which is the way it really is, as far as I can tell, possibly. It doesn't frighten me.
