We can't solve today's problems with the mentality that created them.
The greatest activity of which man is capable: Opening up yet another fragment of the frontier of beauty.
The daily struggle does not arise from a purpose or a program, but from an immediate need.
A happy man is too satisfied with the present to dwell too much on the future.
The more one chases the quanta, the better they hide themselves.
As I have said so many times, God doesn't play dice with the world.
