Prof. Theodore von Kármán

Hungarian-born Theodore von Kármán, whose research contributed greatly to the achievement of supersonic flight, makes an aerodynamic point on a blackboard. “High speed has its uses,” he once said. “For me personally I prefer a slower pace. I like nothing better than to think of myself riding through Paris as my parents did in old Budapest-in a fiacre with a coachman and two horses.”

“My second Rule is, don’t fill more than a page and a half with apologies for not having written sooner!”
