“The fairest thing we can experience is the mysterious. It is the fundamental emotion which

stands at the cradle of true art and true science. He who does not know it, and can no longer wonder, no

longer feel amazement, is as good as dead. A snuffed out candle.”

---- Albert EinsteinForum and Century (1930)
