Everyone knows what a curve is, until he has studied enough mathematics to become confused through the countless number of possible exceptions.

We are born and reborn countless number of times, and it is possible that each being has been our parent at one time or another. Therefore, it is likely that all beings in this universe have familial connections.

Thus, in a sense, mathematics has been most advanced by those who distinguished themselves by intuition rather than by rigorous proofs.

No one knows what he can do until he tries.

I was on the mathematics faculty at M.I.T. from 1951 through until I resigned in the spring of 1959.

He who knows that enough is enough will always have enough.
