In my paper the fact the XY was not equal to YX was very disagreeable to me. I felt this was the only point of difficulty in the whole scheme...and I was not able to solve it.

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.
Werner Heisenberg

Science clears the fields on which technology can build.
Werner Heisenberg

Whenever we proceed from the known to the unkown we may hope to understand, but we may have to learn at the same time a new meaning of the word 'understanding'

The more closely you look at one thing, the less closely can you see something else.

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

Only a few know, how much one must know to know how little one knows.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

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

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.

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

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

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

Can quantum mechanics represent the fact that an electron finds itself approximately in a given place and that it moves approximately with a given velocity, and can we make these approximations so close that they do not cause experimental difficulties?

It will never be possible by pure reason to arrive at some absolute truth.

Where no guiding ideals are left to point the way, the scale of values disappears and with it the meaning of our deeds and sufferings, and at the end can lie only negation and despair. Religion is therefore the foundation of ethics, and ethics the presupposition of life.
Werner Heisenberg

The exact sciences also start from the assumption that in the end it will always be possible to understand nature, even in every new field of experience, but that we may make no a priori assumptions about the meaning of the word understand.
Werner Heisenberg

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

The solution of the difficulty is that the two mental pictures which experiment lead us to form - the one of the particles, the other of the waves - are both incomplete and have only the validity of analogies which are accurate only in limiting cases.

Unless you stake your life, life will not be won.
