Quotation of the day
From Felix Klein
If the activity of a science can be supplied by a machine, that science cannot amount to much, so it is said; and hence it deserves a subordinate place. The answer to such arguments, however, is that the mathematician, even when he is himself operating with numbers and formulas, is by no means an inferior counterpart of the errorless machine, "thoughtless thinker" of Thomas; but rather, he sets for himself his problems with definite, interesting, and valuable ends in view, and he carries them to solution in appropriate and original manner. He turns over to the machine only certain operations which occur frequently in the same way, and it is precisely the mathematician -- one must not forget this -- who invented the machine for his own relief, and who, for his own intelligent ends, designates the tasks which it shall perform.
