Even for the physicist the description in plain language will be a criterion of the degree of understanding that has been reached.

More quotes by Werner Heisenberg
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
Nonsense. Space is blue and birds fly through it.
Werner Heisenberg
After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.
Werner Heisenberg
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
The problems of language here are really serious. We wish to speak in some way about the structure of the atoms. But we cannot speak about atoms in ordinary language.
Werner Heisenberg
Looking at something changes it.
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.
Werner Heisenberg
Uncertainty is NOT I don't know. It is I can't know. I am uncertain does not mean I could be certain.
Werner Heisenberg
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
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.
Werner Heisenberg
What we observe is not nature itself, but nature exposed to our method of questioning.
Werner Heisenberg
My mind was formed by studying philosophy, Plato and that sort of thing.
Werner Heisenberg
The reality we can put into words is never reality itself.
Werner Heisenberg
Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.
Werner Heisenberg
The more closely you look at one thing, the less closely can you see something else.
Werner Heisenberg
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.
Werner Heisenberg
Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.
Werner Heisenberg
Science clears the fields on which technology can build.
Werner Heisenberg
Many people will tell you that an expert is someone who knows a great deal about the subject. To this I would object that one can never know much about any subject. I would much prefer the following definition: an expert is someone who knows some of the worst mistakes that can be made in the subject, and how to avoid them.
Werner Heisenberg
The conception of objective reality ... has thus evaporated ... into the transparent clarity of mathematics that represents no longer the behavior of particles but rather our knowledge of this behavior.
Werner Heisenberg
