Wikipedia did it again.

Wikipedia usually cost a few hours of my life. I jus have to search on 1 subject, it can lead to endless reading material. Its amazing, the amount of information wiki has.

Cos Euler appeared on 1 of the chapters frm suzumiya haruhi, the Euler Characteristic for planes and stuff

http://en.wikipedia.org/wiki/Euler_characteristic

Den frm Euler, read to this other maths freak

http://en.wikipedia.org/wiki/Paul_Erd%C5%91s

Some people are jus incredible. When i read these shitz, the formulas in those pages are abit the imba, cannot understand sia. And all those theory shitz that they come up, how did they come up with that in the first place?

Even maths could be of such fun.

Argh my head is spinning~

Ok start on phy now.
