The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.

[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.
Werner Heisenberg
Image
Every tool carries with it the spirit by which it has been created.
Werner Heisenberg
Image
Even for the physicist the description in plain language will be a criterion of the degree of understanding that has been reached.
Werner Heisenberg
Image
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
Image
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.
Werner Heisenberg
Image
The world thus appears as a complicated tissue of events, in which connections of different kinds alternate or overlap or combine and thereby determine the texture of the whole.
Werner Heisenberg
Image
What we observe is not nature itself but nature exposed to our method of questioning. Our scientific work in physics consists in asking questions about nature in the language that we possess and trying to get an answer from experiment by the means that are at our disposal.
Werner Heisenberg
Image
There are things that are so serious that you can only joke about them.
Werner Heisenberg
Image
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'
Werner Heisenberg
Image
The ontology of materialism rested upon the illusion that the kind of existence, the direct actuality of the world around us, can be extrapolated into the atomic range. This extrapolation is impossible, however.
Werner Heisenberg
Image
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?
Werner Heisenberg
Image
What we observe is not nature itself, but nature exposed to our method of questioning.
Werner Heisenberg
Image
I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.
Werner Heisenberg
Image
The reality we can put into words is never reality itself.
Werner Heisenberg
Image
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
Image
It will never be possible by pure reason to arrive at some absolute truth.
Werner Heisenberg
Image
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.
Werner Heisenberg
Image
Every word or concept, clear as it may seem to be, has only a limited range of applicability.
Werner Heisenberg
Image
The 'path' comes into existence only when we observe it.
Werner Heisenberg

It is probably true quite generally that in the history of human thinking the most fruitful developments frequently take place at those points where two different lines of thought meet.
