Mathematician's Apoplexy

G. H. Hardy (1877-1947) wrote A Mathematician's Apology in 1940, late in life, during wartime. It shows. The book is short, argumentative, often wrong. Hardy insists that the "pure" parts of mathematics and physics are irrelevant to ordinary life. How silly — increasingly, obviously so! His thesis that knowing "...a little chemistry, physics, or physiology has no value at all in ordinary life"? Ditto. His claim, "Real mathematics has no effects on war. No one has yet discovered any warlike purpose to be served by the theory of numbers or relativity, and it seems very unlikely that anyone will do so for many years ..."? Already wrong when he wrote them, more blatantly so now.

Wiser, perhaps, if Hardy had stood on his head, smiled, and said:
