The very act of observing disturbs the system.

Modern physics has changed nothing in the great classical disciplines of, for instance, mechanics, optics, and heat. Only the conception of hitherto unexplored regions, formed prematurely from a knowledge of only certain parts of the world, has undergone a decisive transformation. This conception, however, is always decisive for the future course of research.

Therefore, the two processes, that of science and that of art, are not very different. Both science and art form in the course of the centuries a human language by which we can speak about the more remote parts of reality, and the coherent sets of concepts as well as the different styles of art are different words or groups of words in this language.

The Same organizing forces that have shaped nature in all her forms are also responsible for the structure of our minds.

When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.

Not only is the Universe stranger than we think, it is stranger than we can think.

The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite.
