Niels Bohr was a world-renowned Danish physicist, known for his work in the field of quantum mechanics and atomic structure.
One of his most significant statements regarding atomic structure states that electrons move in orbits of definite power but can jump from one to another if they get more energy. His theory about atomic structure is called the Bohr atomic model.
Niels Bohr was awarded the prestigious Nobel Prize in physics in 1922 for his contributions to his field. Learn all about him with these Niels Bohr quotes.

- Niels Bohr.
4. "Every sentence I utter must be understood not as an affirmation, but as a question."

5. "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."
- Niels Bohr.
6. "Criticism is exactly what I want, and I hope that you will find that the paper has been improved."
- Niels Bohr.
7. "The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth."

8. "I believe that a closer analysis offers the proper answer to such paradoxes regarding the nature of light as brought forward especially by Lewis."
- Niels Bohr.
9. "Every valuable human being must be a radical and a rebel, for what he must aim at is to make things better than they are."
- Niels Bohr.
10. “There 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.
11. “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.
12. "A point not directly referred to in the article but in which I have been very interested lately is the question of the uni-direction of time."
- Niels Bohr.
13. "Everything we call real is made of things that cannot be regarded as real."
- Niels Bohr.
14. "I am not quite in agreement with your emphasis on the necessity to develop ‘new’ concepts."
- Niels Bohr.
15. "We have not only, as far as I can see, no basis for such a new-fashioning so far, but the ‘old’ empirical concepts appear to me to be inseparably linked to the foundations of the human means of visualization."
- Niels Bohr.

16. "We have to do with the recognition of an inescapable feature of complementarity that emerges in an analysis of the concept of observation and which in many respects recalls the recognition of the general [feature of] relativity."
- Niels Bohr.
17. "I believe that it is already possible to say that any application of classical concepts that permits an unambiguous definition, may also be ascribed a physical interpretation."
- Niels Bohr.
18. "In the case of interaction between several individuals - and altogether whenever there can be a question of quantization - the uncertainty relations must always be applied with caution."
- Niels Bohr.
19. "The range of values of the variables that may be experimentally ascertained is smaller, compared to the range of values of the individual eigensolutions, the larger the quantum number."
- Niels Bohr.
20. "In this connection the ascertainment that the atom is in a definite state is always associated with a renunciation of the knowledge of the phase of the corresponding eigensolution."
- Niels Bohr.
21. "All knowledge presents itself within a conceptual framework adapted to account for previous experience and that any such frame may prove too narrow to comprehend new experiences."
- Niels Bohr.
22. "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.
23. "I hope soon in a short note to be able to show that certain paradoxes in the quantum-theoretical treatment of radiation phenomena may be illuminated by the remark that the fixation of a direction of time is intimately related to the concept of observation."
- Niels Bohr.
24. "For a parallel to the lesson of atomic theory regarding the limited applicability of such customary idealizations, we must in fact turn to quite other branches of science…"
- Niels Bohr.
25. "After the many years of struggling in the dark, I feel perhaps especially strongly the fulfilment of the old hopes, brought about by the new discoveries of yourself and others."
- Niels Bohr.
