"The Religion that is afraid of science dishonours God and commits suicide. It acknowledges that it is not equal to the whole of truth, that it legislates, tyrannizes over a village of God's empires but is not the immutable universal law. Every influx of atheism, of skepticism is thus made useful as a mercury pill assaulting and removing a diseased religion and making way for truth."

"Science does not know its debt to imagination."

"I'm not religious in the normal sense. I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws."

"Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it."

"I want to know God's thoughts; the rest are details."

"When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity."

"Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

"While all other sciences have advanced, that of government is at a standstill - little better understood, little better practiced now than three or four thousand years ago."

"When I die, I'm leaving my body to science fiction."

"Success is a science; if you have the conditions, you get the result."

"Romance should never begin with sentiment. It should begin with science and end with a settlement."

"Democracy is the art and science of running the circus from the monkey cage."

"Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter."

"Everything should be made as simple as possible, but no simpler."

"Shun no toil to make yourself remarkable by some talent or other; yet do not devote yourself to one branch exclusively. Strive to get clear notions about all. Give up no science entirely; for science is but one."
