Niels Bohr Quantum Theory Quotes & Sayings

Our deepest description of physical reality, in quantum theory and in the four Core Theories of forces (gravitation, electromagnetism, strong and weak forces), bring in concepts that call to mind yin and yang. Niels Bohr, an influential founder of quantum theory, saw strong parallels between his concept of complementarity and the unified duality of yin-yang. He designed a coat of arms for himself, in which the yin-yang figures centrally (see figure 42, page 324). Our Core Theories center on the interplay between lightlike space filling fluids (yang) and substances (yin) they both direct and respond to. — Frank Wilczek

Despite the earnest belief of most of his fans, Einstein did not win his Nobel Prize for the theory of relativity, special or general. He won for explaining a strange effect in quantum mechanics, the photoelectric effect. His solution provided the first real evidence that quantum mechanics wasn't a crude stopgap for justifying anomalous experiments, but actually corresponds to reality. And the fact that Einstein came up with it is ironic for two reasons. One, as he got older and crustier, Einstein came to distrust quantum mechanics. Its statistical and deeply probabilistic nature sounded too much like gambling to him, and it prompted him to object that "God does not play dice with the universe." He was wrong, and it's too bad that most people have never heard the rejoinder by Niels Bohr: "Einstein! Stop telling God what to do. — Sam Kean

Chinese dialectical reasoning had an impact on the physicist Niels Bohr, who was highly knowledgeable about Eastern thought. He attributed his development of quantum theory in part to the metaphysics of the East. There had been a centuries-long debate in the West about whether light consists of particles or waves. Belief in one was assumed to contradict and render impossible belief in the other. Bohr's solution was to say that light can be thought of in both ways. In quantum theory, light can be viewed either as a particle or as a wave. Just never both at the same time. — Richard E. Nisbett

Niels Bohr brainwashed a whole generation of theorists into thinking that the job (interpreting quantum theory) was done 50 years ago. — Murray Gell-Mann

Copenhagen interpretation Niels Bohr's combination of instrumentalism, anthropocentrism and studied ambiguity, used to avoid understanding quantum theory as being about reality. — David Deutsch
