Paul Erdős

I am not a mathematician. I am a problem solver.

The purpose of life is to prove and to conjecture.

A problem worthy of attack proves its worth by fighting back.

It will be another million years, at least, before we understand the primes.

I'm not a mathematician. I'm a problem solver.

The first sign of senility is that a man forgets his theorems. The second sign is that he forgets to zip up. The third sign is that he forgets to zip down.

Mathematics is not yet ready for such problems.

I have no home. I have a brain and a suitcase, and that's all.

The SF has created many problems, but also many theorems.

I hope we will be able to finish this proof before I die, but I am not sure.
