"A considreable portion of my high school trigonometry course was devoted to the solution of oblique triangles... I have still not had an excuse for using my talents for solving oblique triangles. If a professional mathematician never uses these dull techniques in a highly varied career, why must all high school students devote several weeks to the subject?"

I confess that I have hitherto indulged very little in philanthropic enterprises.... While my townsmen and women are devoted in somany ways to the good of their fellows, I trust that one at least may be spared to other and less humane pursuits. You must have a genius for charity as well as for anything else. As for Doing-good, that is one of the professions which are full.
