When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible. Nevertheless, no one doubts that we are confronted with a causal connection whose causal components are in the main known to us. Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.

In every true searcher of Nature there is a kind of religious reverence.

The monotony and solitude of a quiet life stimulates the creative mind.

If I were to start taking care of my grooming, I would no longer be my own self.

The more I learn of physics, the more I am drawn to metaphysics.

Work is the only thing that gives substance to life.

Physical concepts are free creations of the human mind, and are not, however it may seem, uniquely determined by the external world.
