The first mathematician who sprang to mind, however, is Leonhard Euler, who was a very creative and extremely prolific Swiss mathematician, whose contributions range far and wide through several branches of maths. He’s responsible for the constant e, for example, named after him.

You could also do Kurt Godel, who is an interesting mathematician. He is responsible for proving definitively and logically that current mathematical techniques will never be able to answer all questions, no matter how much we tweak them. He also did some other cool things, like providing a little mathematical proof of god. He was also a good friend and inspiration to Einstein, and he went insane and died. Pretty cool guy.

Uhh, who else? You could try Greog Cantor, who is, in a way, similar to Godel, but probably not as interesting. He made huge leaps and bounds in set theory, and proved that counting numbers, integers, and rational numbers all have the same number of elements, but real numbers and irrational numbers do not. That is, you can count all possible fractions, but you can’t count all real numbers. In that way, he proved that there was more than one type of infinity. He then wondered if there was a kind of infinity between the two infinities, and he obsessed over that problem until his death. Then, Godel (again), proved that the problem was unsolvable within a couple of years after his death. alwbsok
