The Art of Tetman Callis

“It will turn out . . . that many simple things can be deduced mathematically more rapidly than they can be really understood in a fundamental or simple sense. This is a strange characteristic, and . . . there are circumstances in which mathematics will produce results which no one has really been able to understand in any direct fashion.” – Richard P. Feynman, The Feynman Lectures on Physics, Vol. I (emphasis in original)
