“One of the great tragedies of mankind is that morality has been hijacked by religion. So now people assume that religion and morality have a necessary connection. But the basis of morality is really very simple and doesn't require religion at all.”
― Arthur C. Clarke

“Physics is like sex: sure, it may give some practical results, but that's not why we do it.”

“I learned an important lesson: Never take the obvious for granted. Once upon a time, it was so obvious that a four-pound rock would plummet earthward twice as fast as a two-pound rock that no one ever bothered to test it.

― V.S. Ramachandran, The Tell-Tale Brain: A Neuroscientist's Quest for What Makes Us Human

“Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night.”
― Isaac Asimov
