Physics is becoming too difficult for the physicists.

Is mathematics doomed to suffer the same fate as other sciences that have split into separate branches?... Mathematics is, in my opinion, an indivisible whole... May the new century bring with it ingenious champions and many zealous and enthusiastic disciples.

If I were to awaken after having slept for a thousand years, my first question would be: Has the Riemann hypothesis been proven?

I didn't work especially hard at mathematics at school, because I knew that's what I'd be doing later.

The arithmetical symbols are written diagrams and the geometrical figures are graphic formulas.

If one were to bring ten of the wisest men in the world together and ask them what was the most stupid thing in existence, they would not be able to discover anything so stupid as astrology.

The further a mathematical theory is developed, the more harmoniously and uniformly does its construction proceed, and unsuspected relations are disclosed between hitherto separated branches of the science.
