02UndatedThe opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.Niels Bohr / quote ↗
04UndatedThere are trivial truths and there are great truths. The opposite of a trivial truth is plainly false. The opposite of a great truth is also true.Niels Bohr / quote ↗
05UndatedAn expert is a person who has made all the mistakes that can be made in a very narrow field.Niels Bohr / quote ↗
06UndatedThose who are not shocked when they first come across quantum theory cannot possibly have understood it.Niels Bohr / quote ↗
08UndatedThe 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 / quote ↗
09UndatedEverything we call real is made of things that cannot be regarded as real.Niels Bohr / quote ↗
10UndatedI myself find the division of the world into an objective and a subjective side much too arbitrary. The fact that religions through the ages have spoken in images, parables, and paradoxes means simply that there are no other ways of grasping the reality to which they refer. But that does not mean that it is not a genuine reality. And splitting this reality into an objective and a. subjective side won't get us very far.Niels Bohr / quote ↗
12UndatedThe meaning of life consists in the fact that it makes no sense to say that life has no meaning.Niels Bohr / quote ↗
13Undated[About describing atomic models in the language of classical physics:]We must be clear that 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 / quote ↗
14UndatedEvery sentence I utter must be understood not as an affirmation but as a question.[A caution he gives his students, to be wary of dogmatism.]Niels Bohr / quote ↗
17UndatedHow wonderful that we have met with a paradox. Now we have some hope of making progress.Niels Bohr / quote ↗
18UndatedAn expert is a man who has made all the mistakes which can be made in a very narrow field.Niels Bohr / quote ↗
19UndatedThe best weapon of a dictatorship is secrecy, but the best weapon of a democracy should be the weapon of openness.Niels Bohr / quote ↗
21UndatedWhile the finish given to our picture of the world by the theory of relativity has already been absorbed into the general scientific consciousness, this has scarcely occurred to the same extent with those aspects of the general problem of knowledge which have been elucidated by the quantum theory.Niels Bohr / quote ↗
22UndatedThe opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth.Niels Bohr / quote ↗
23UndatedEvery great and deep difficulty bears in itself its own solution. It forces us to change our thinking in order to find it.Niels Bohr / quote ↗
24UndatedTechnology has advanced more in the last thirty years than in the previous two thousand. The exponential increase in advancement will only continue.Niels Bohr / quote ↗
