Image
Not only is the Universe stranger than we think, it is stranger than we can think.
Werner Heisenberg
Image
A consistent pursuit of classical physics forces a transformation in the very heart of that physics.
Werner Heisenberg
Image
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
Image
The structure underlying the phenomena is not given by material objects like the atoms of Democritus but by the form that determines the material objects. The Ideas are more fundamental than the objects.
Werner Heisenberg
Image
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
Image
Only a few know, how much one must know to know how little one knows.
Werner Heisenberg
Image
Every word or concept, clear as it may seem to be, has only a limited range of applicability.
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
[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
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
Image
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
Image
The very act of observing disturbs the system.
Werner Heisenberg
Image
The reality we can put into words is never reality itself.
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
The basic idea is to shove all fundamental difficulties onto the neutron and to do quantum mechanics in the nucleus.
Werner Heisenberg
Image
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.
Werner Heisenberg
Image
Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.
Werner Heisenberg
Image
The 'path' comes into existence only when we observe it.
Werner Heisenberg
Image
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
Image
Every tool carries with it the spirit by which it has been created.
Werner Heisenberg
Image
It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.
Werner Heisenberg
Image
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
Image
Looking at something changes it.
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.
