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.

What we observe is not nature itself, but nature exposed to our method of questioning.
Werner Heisenberg
Image
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
Image
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.
Werner Heisenberg

The one who insists on never uttering an error must remain silent.
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
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
The basic idea is to shove all fundamental difficulties onto the neutron and to do quantum mechanics in the nucleus.
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
Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics
Werner Heisenberg
Image
There is a fundamental error in separating the parts from the whole, the mistake of atomizing what should not be atomized. Unity and complementarity constitute reality.
Werner Heisenberg

The 'path' comes into existence only when we observe it.
Werner Heisenberg
Image
Science clears the fields on which technology can build.
Werner Heisenberg
Image
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
Image
The reality we can put into words is never reality itself.
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 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 more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
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'

My mind was formed by studying philosophy, Plato and that sort of thing.
