I believe that the existence of the classical path can be pregnantly formulated as follows: The path comes into existence only when we observe it.

By getting to smaller and smaller units, we do not come to fundamental or indivisible units. But we do come to a point where further division has no meaning.

There are things that are so serious that you can only joke about them.

In general, scientific progress calls for no more than the absorption and elaboration of new ideas- and this is a call most scientists are happy to heed.

A consistent pursuit of classical physics forces a transformation in the very heart of that physics.

[T]he atoms or elementary particles themselves are not real they form a world of potentialities or possibilities rather than one of things or facts.

Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.

The discontinuous 'reduction of the wave packets' which cannot be derived from Schroedinger's equation is ... a consequence of the transition from the possible to the actual.

The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving and that this motion has caused the feeling that the ground would be cut from science

Uncertainty is NOT I don't know. It is I can't know. I am uncertain does not mean I could be certain.

In the strict formulation of the law of causality—if we know the present, we can calculate the future—it is not the conclusion that is wrong but the premise. On an implication of the uncertainty principle.

The 'path' comes into existence only when we observe it.

Whether we electrons, light quanta, benzol molecules, or stones, we shall always come up against these two characteristics, the corpuscular and the undular.

I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.

After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.

Natural science, does not simply describe and explain nature it is part of the interplay between nature and ourselves

Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.

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.

Nonsense. Space is blue and birds fly through it.

I think that modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense they are forms, ideas which can be expressed unambiguously only in mathematical language.

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