“To the extent math refers to reality, we are not certain; to the extent we are certain, math does not refer to reality.”

Albert Einstein

“Yes, we have to divide up our time like that, between our politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever.”

“Mathematics, rightly viewed, posses not only truth, but supreme beauty; a beauty cold and austere, like that of sculpture”

Bertrand Russell

“How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom”

“As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.”

“Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore.”

“Some mathematician has said pleasure lies not in discovering truth, but in seeking it.”

Leo Nikolaevich Tolstoy
