Today's quotes from a science fiction author, Arthur C. Clarke:

Clarke's Three Laws

Clarke's First Law: When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.

"Hazards of Prophecy: The Failure of Imagination" in Profiles of the Future (1962)

Clarke's Second Law: The only way of discovering the limits of the possible is to venture a little way past them into the impossible.

"Hazards of Prophecy: The Failure of Imagination" in Profiles of the Future (1962)

Clarke's Third Law: Any sufficiently advanced technology is indistinguishable from magic.
