More quotes by Werner Heisenberg
The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
Werner Heisenberg
It was about three o'clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me ... At first I was deeply shaken ... I was so excited that I could not think of sleep. So I left the house ... and awaited the sunrise on top of a rock.
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
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
Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.
Werner Heisenberg
Nature is made in such a way as to be able to be understood. Or perhaps I should put it-more correctly-the other way around, and say that we are made in such a way as to be able to understand Nature.
Werner Heisenberg
The reality we can put into words is never reality itself.
Werner Heisenberg
The 'path' comes into existence only when we observe it.
Werner Heisenberg
There are things that are so serious that you can only joke about them.
Werner Heisenberg
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
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
Werner Heisenberg
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
Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics
Werner Heisenberg
Both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different
Werner Heisenberg
...separation of the observer from the phenomenon to be observed is no longer possible.
Werner Heisenberg
Nonsense. Space is blue and birds fly through it.
Werner Heisenberg
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.
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
Every tool carries with it the spirit by which it has been created.
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
