Physics of Nanostructures and Advanced Materials

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.

All science is either physics or stamp collecting.

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