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 HEISENBERGThe 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.

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

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.
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 -
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 -
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 -
Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves.
WERNER HEISENBERG -
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.
WERNER HEISENBERG -
The single life is bearable to me only through my work in science, but for the long term, it would be very bad if I had to make do without a very young person next to me.
WERNER HEISENBERG -
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 -
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.

Reports in Washington show that our reasoning was just like that of your physicists.

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 -
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 -
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 -
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.
