Quote
THE SCIENTIFIC THEORIST IS NOT TO BE ENVIED. FOR NATURE, OR MORE PRECISELY EXPERIMENT, IS AN INEXORABLE AND NOT VERY FRIENDLY JUDGE OF HIS WORK. IT NEVER SAYS "YES" TO A THEORY. IN THE MOST FAVORABLE CASES IT SAYS "MAYBE", AND IN THE GREAT MAJORITY OF CASES SIMPLY "NO"... PROBABLY EVERY THEORY WILL SOME DAY EXPERIENCE ITS "NO" - MOST THEORIES, SOON AFTER CONCEPTION. -- A.EINSTEIN, NOV 11, 1922.
