ANECDOTES:

… When Einstein was five years old, his father showed him a pocket compass. The little boy was deeply impressed by the mysterious behavior of the compass needle, which kept pointing in the same direction no matter which way the compass was turned. He later said he felt that “something deeply hidden had to be behind things.”
