Niels Henrik David Bohr, born on October 7, 1885, in Copenhagen, Denmark, was a groundbreaking physicist whose revolutionary work in quantum theory transformed modern science. He developed the Bohr model of the atom and earned the Nobel Prize in Physics in 1922 for his discoveries in atomic structure. Bohr’s career also included significant contributions to nuclear physics and the complementarity principle, influencing fields from philosophy to international policy. His quotes, often drawn from books, interviews, and speeches, reflect a profound blend of scientific rigor and existential thought. In this list, you’ll find 15 of Niels Bohr’s quotes about life, showcasing his insights on truth, uncertainty, and human experience sourced from various credible outlets.
15 Niels Bohr Quotes
1. “The opposite of a correct statement is a false statement, but the opposite of a profound truth may well be another profound truth.” (Book, “Atomic Physics and Human Knowledge,” 1958)
2. “Prediction is very difficult, especially about the future.” (Interview, New York Times, 1954)
3. “Everything we call real is made of things that cannot be regarded as real.” (Nobel Lecture, 1922)
4. “An expert is a man who has made all the mistakes that can be made in a very narrow field.” (Interview, n.d., commonly attributed)
5. “We all agree that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.” (Letter, to a colleague, 1920s)
6. “The best weapon of a dictatorship is secrecy, but the best weapon of a democracy should be the weapon of openness.” (Speech, United Nations, 1950)
7. “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.” (Essay, “The Unity of Knowledge,” 1954)
8. “There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.” (Book, “Atomic Theory and the Description of Nature,” 1934)
9. “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.” (Interview, 1950s)
10. “It is a great pity that human beings cannot find all their satisfaction in scientific contemplativeness.” (Book, “Essays 1958-1962 on Atomic Physics and Human Knowledge,” 1963)
11. “We must be clear that when it comes to atoms, we cannot speak in everyday language.” (Speech, Solvay Conference, 1927)
12. “The great extension of our experience in recent years has brought to light the insufficiency of our simple mechanical conceptions and, as a consequence, has shaken the foundation on which the customary interpretation of observation rests.” (Book, “The Theory of Spectra and Atomic Constitution,” 1922)
13. “In the great drama of existence, we are both actors and spectators.” (Attributed interview, 1930s)
14. “Truth and clarity are complementary.” (Essay, “Discussion with Einstein,” 1949)
15. “The more we learn about the universe, the more we find in it is subject to the same principles that govern our own lives.” (Speech, commemorative event, 1955)
