Hans Reichenbach...on physics

If one knows physics only from a distance, it may appear to be merely strange names and mathematical formulae, and one may come to believe that it is an affair of the learned alone, ingeneously and wisely constructed, but without significance for men of other interests and problems. An yet one could do no worse injustice to physics than to turn away, repelled by this hard shell of technical terms with which it has surrounded itself. Whoever succeeds in looking behind this wall...will find there a science full of living problems, full of inner motion, full of the intense endeavor to find answers to the questions of the truth-seeking spirit.
