The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position then exactly measured, the position for times previous to the measurement may be calculated.

Bohr’s influence on the physics and the physicists of our century was stronger than that of anyone else, even than that of Albert Einstein.

I believe this uranium business will give the Anglo-Saxons such tremendous power that Europe will become a bloc under Anglo-Saxon domination. If that is the case, it will be a very good thing. I wonder whether Stalin will be able to stand up to the others as he has done in the past.

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.

In America, it was decided to attempt the production of atomic bombs with an effort that would constitute a large part of the collective American war effort.
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.

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 -
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 -
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 -
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.
WERNER HEISENBERG -
Whoever dedicates his life to searching out particular connections of nature will spontaneously be confronted with the question how they harmoniously fit into the whole.
WERNER HEISENBERG -
Certainly, in the course of time, the splendid things will separate from the hateful.

In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.

With all this information available, at least to privileged persons, I cannot understand why it is generally held in the United States that we completely missed the basic principle of the bomb until after Hiroshima.
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.

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.
