"Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion."
-- Albert Einstein, in a letter to the family of his lifelong friend Michele Besso, after learning of his death, (March 1955) as quoted in Disturbing the Universe (1979) by Freeman Dyson Ch. 17 "A Distant Mirror."
