It is still an unending source of surprise for me to see how a few scribbles on a blackboard or on a sheet of paper could change the course of human affairs.
Stanislaw Ulam
(Ulam is known to the cognoscenti as the father of the H-bomb. Everyone hates Edward Teller, who is called - in these circles - the mother of the bomb.). My thanks to Milton Obote, as usual the best.
