Mathematics knows no races or geographic boundaries; for mathematics, the cultural world is one country.

Mathematical science is in my opinion an indivisible whole, an organism whose vitality is conditioned upon the connection of its parts.

No one shall expel us from the paradise that Cantor has created for us.

He who seeks for methods without having a definite problem in mind seeks in the most part in vain.

One can measure the importance of a scientific work by the number of earlier publications rendered superfluous by it.

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

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.

Mathematics is a game played according to certain simple rules with meaningless marks on paper.

How thoroughly it is ingrained in mathematical science that every real advance goes hand in hand with the invention of sharper tools and simpler methods which, at the same time, assist in understanding earlier theories and in casting aside some more complicated developments.

Physics is becoming too difficult for the physicists.

A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street.

The art of doing mathematics consists in finding that special case which contains all the germs of generality.
