De uitdaging is onze redding

28 april 2009 | I'd like to begin today with a story of a previous visitor who also addressed this august body. In April of 1921, Albert Einstein visited the United States for the first time. And his international credibility was growing as scientists around the world began to understand and accept the vast implications of his theories of special and general relativity. And he attended this annual meeting, and after sitting through a series of long speeches by others, he reportedly said, "I have just got a new theory of eternity."
