Didactics of Physics

The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."

The supreme task of the physicist is the discovery of the most general elementary laws from which the world-picture can be deduced logically. But there is no logical way to the discovery of these elemental laws. There is only the way of intuition, which is helped by a feeling for the order lying behind the appearance, and this Einfühlung [literally, empathy or 'feeling one's way in'] is developed by experience.

The physical doctrine of the atom has got into a state which is strongly suggestive of the epicycles of astronomy before Copernicus.
