In the great drama of existence we are audience and actors at the same time.

A visitor to Niels Bohr's country cottage, noticing a horseshoe hanging on the wall, teasing the eminent scientist about this ancient superstition. Can it be true that you, of all people, believe it will bring you luck?' 'Of course not,' replied Bohr, 'but I understand it brings you luck whether you believe it or not.'

How wonderful that we have met with a paradox. Now we have some hope of making progress.
Niels Bohr
Image
If we couldn't laugh at ourselves, that would be the end of everything.
Niels Bohr

It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we say about nature.
Niels Bohr
Image
Physics is the belief that a simple and consistent description of nature is possible.

Opposites are not contradictory but complementary.

A physicist visits a colleague and notices a horseshoe hanging on the wall above the entrance. 'Do you really believe that a horseshoe brings luck?' he asks. 'No,' replies the colleague, 'but I've been told that it works even if you don't believe in it.'

There is no hope for any speculation that does not look absurd at first glance.

Our task is not to penetrate the essence of things, the meaning of which we do not know anyway, but rather to develop concepts which allow us to talk in a productive way about phenomena in nature
Niels Bohr

Nothing exists until it is measured.

If you have a correct statement, then the opposite of a correct statement is of course an incorrect statement, a wrong statement. But when you have a deep truth, then the opposite of a deep truth may again be a deep truth.

No paradox, no progress.
Niels Bohr

When it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.
Niels Bohr

Einstein, stop telling God what to do!
Niels Bohr

No, no, you're not thinking you're just being logical.
Niels Bohr
Image
The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively.
Niels Bohr

Never express yourself more clearly than you are able to think.
Niels Bohr
Image
Truth is something that we can attempt to doubt, and then perhaps, after much exertion, discover that part of the doubt is not justified.

Predition is risky, especially of the future.
