Un petit lien trouvé sur le site de l’Inria pour les amateurs de maths :

http://www-sop.inria.fr/mefisto/java/tutorial1/node14.html

Personnellement, je n'y ai rien compris à ce problème de probabilités géométriques posé (et résolu) par Buffon.

La démonstration est juste époustouflante...

Amicalement.

La démonstration m'apparaitra époustouflante quand on m'aura expliqué comment ils ont déjà obtenu leur première équation....

J'en suis tout juste à avoir compris que les sinus, cosinus, pouvait représenter un nombre de même que racine de 1 représente la valeur mathématique que prend la diagonale d'un carré d'un centimètre de côté.... La diagonale existe, mais on ne peut pas la calculer exactement....autrement que sous la forme de racine de 1.

Alors là moi j'y pige que pouic... Je sais que si on repart du début, doucement je comprendrais... parce que cela à un sens.... Mais pour l'instant... Je ne suis pas époustouflé du tout... C'est comme si tu me mettais une pièce de Shakespeare en anglais du XVI ème siècle et que tu me dis traduit.... Pourtant elle a un sens et qui peut être chouette en plus.....

HI HAN !!!!!!!!!!!!!!!
