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.
Niels Bohr

It is very difficult to make an accurate prediction, especially about the future.
Niels Bohr

Rutherford is a man you can rely on he comes regularly and enquires how things are going and talks about the smallest details - Rutherford is such an outstanding man and really interested in the work of all the people around him.
Niels Bohr
Image
There are trivial truths and the great truths. The opposite of a trivial truth is plainly false. The opposite of a great truth is also true.
Niels Bohr

Anyone who can contemplate quantum mechanics without getting dizzy hasn't understood it.
Niels Bohr

We are trapped by language to such a degree that every attempt to formulate insight is a play on words.
Niels Bohr

In physics we deal with states of affairs much simpler than those of psychology and yet we again and again learn that our task is not to investigate the essence of things-we do not at all know what this would mean&mashbut to develop those concepts that allow us to speak with each other about the events of nature in a fruitful manner.

Never express yourself more clearly than you are able to think.
Niels Bohr

Some subjects are so serious that one can only joke about them.
Niels Bohr
Image
Predition is risky, especially of the future.
Niels Bohr
Image
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
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
Image
I go into the Upanishads to ask questions.
Niels Bohr
Image
Anybody who is not shocked by this subject has failed to understand it. [of quantum mechanics]
Niels Bohr
Image
If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.
Niels Bohr
Image
An independant reality in the ordinary physical sense can neither be ascribed to the phenomenon nor to the agencies of observation.
Niels Bohr
Image
We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough.
Niels Bohr
Image
You must come to Copenhagen to work with us. We like people who can actually perform thought experiments!

There are some things so serious you have to laugh at them.
