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

If this were the whole truth, we should, when entering into a new field, introduce only such quantities as can directly be observed, and formulate natural laws only by means of these quantities.

If we made atomic bombs, we would bring about a terrible change in the world. Who knows what would happen from this?

In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.
WERNER HEISENBERG -
Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.
WERNER HEISENBERG -
In Germany, an effort one thousandth the scale of the American was applied to the problem of producing atomic energy that would drive engines.
WERNER HEISENBERG -
I would like to mention astrophysics; in this field, the strange properties of the pulsars and quasars, and perhaps also the gravitational waves, can be considered as a challenge.
WERNER HEISENBERG -
Certainly, in the course of time, the splendid things will separate from the hateful.

If the lecture is good, then everything is too smooth. That’s the same in music: if the performance is too good, you really don’t enjoy it, because it just goes by, and you can never penetrate into the heart of it.

Every word or concept, clear as it may seem to be, has only a limited range of applicability.
WERNER HEISENBERG -
There is a great difference between discoveries and inventions. With discoveries, one can always be skeptical, and many surprises can take place. In the case of inventions, surprises can really only occur for people who have not had anything to do with it.
WERNER HEISENBERG -
It is generally believed that our science is empirical and that we draw our concepts and our mathematical constructs from the empirical data.
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 -
Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves.
