today is the 9th of september 2009 and in 18 days it's my birthday...
I just finished solving differential equations problems, I'm dead tired of them, because almost half of the problems I don't know what to do with. So tomorrow I'm going to bug someone who knows about these equations and how to solve them, with my questions... :D
Anyways, it's too late to think about them now.
Good night :)
and happy 090909! ^_^
