No Mathematician Should Ever Allow Himself To Forget That Mathematics, More Than Any Other Art Or Science, Is A Young Man's Game

If I Could Prove By Logic That You Would Die In Five Minutes, I Should Be Sorry You Were Going To Die, But My Sorrow Would Be Very Much Mitigated By Pleasure In The Proof.

The Primes Are The Raw Material Out Of Which We Have To Build Arithmetic, And Euclid's Theorem Assures Us That We Have Plenty Of Material For The Task.

This May Be True; Indeed It Is Probable, Since The Sensational Triumphs Of Einstein, That Stellar Astronomy And Atomic Physics Are The Only Sciences Which Stand Higher In Popular Estimation.

No Mathematician Should Ever Allow Him To Forget That Mathematics, More Than Any Other Art Or Science, Is A Young Man's Game. ... Galois Died At Twenty-one, Abel At Twenty-seven, Ramanujan At Thirty-three, Riemann At Forty. There Have Been Men Who Have Done Great Work Later; ... [but] I Do Not Know Of A Single Instance Of A Major Mathematical Advance Initiated By A Man Past Fifty. ... A Mathematician May Still Be Competent Enough At Sixty, But It Is Useless To Expect Him To Have Original Ideas.
