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.

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.

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 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.

I think that if a United States of Europe were to be formed, it would be in our interests to fight for it, as all our old traditions would remain in such a united Europe, whereas if we were to start now as part of the Russian Empire, everything that had ever been in Germany would disappear.

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.

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.

It is generally believed that our science is empirical and that we draw our concepts and our mathematical constructs from the empirical data.

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.

The end of the First World War had thrown Germany’s youth into great turmoil. The reins of power had fallen from the hands of a deeply disillusioned older generation, and the younger ones drew together in larger and smaller groups to blaze new paths or, at least, to discover a new star to steer by.

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

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.

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.

Sometimes a poor performance is better for enjoyment, because you can look at those things that were wrong and analyze them.

Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves.

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.
