Worse, although latent, the characteristic was predominent and increasing." Philip E.

Suddenly it has become indispensable, and would have had to be developed in a hurry had it not been ready to hand. This has been the story again and again throughout the history of mathematics: no part of mathematics is ever, in the long run, 'useless.' Most of number theory has very few 'practical' applications. That does not reduce its importance, and if anything it enhances its fascination. No one can predict when what seems to be a most obscure theorem may suddenly be called upon to play some vital and hitherto unsuspected role." (Ten years later, Diffie-Hellman public key cryptography was published.)
