Inspirational Quotes by Niels Bohr (Danish Physicist)

Niels Bohr (1885–1962,) fully Niels Hendrik David Bohr, was a Danish physicist and pioneer in quantum physics. This winner of the 1922 Nobel Prize in Physics was a towering figure of 20th-century physics.

Born in Copenhagen, Bohr was the first to apply quantum theory in a consistent framework to explain the arrangement of electrons in the atom. He proposed that atoms were composed of a small, dense nucleus that is orbited by electrons at a fixed distance from the nucleus and that elements are determined by the number of electrons in the outer orbits of their atoms. When electrons move from one energy level to another, they emit discrete quanta of energy.

Bohr’s model accounted for the chemical properties of the elements and the main features in their spectra. Bohr’s theory has become the foundation of modern quantum-mechanical models. Bohr also developed the revolutionary principle of complementarity: that things like light or electrons can have a dual nature—as a particle and a wave, for example—but we can only experience one aspect of their nature at a time.

Bohr escaped from German-occupied Denmark in 1943 and helped Britain and the U.S. develop the atom bomb. He later became concerned about the implications of atomic weapons and stressed the need to study the peaceful applications of atomic energy.

Bohr’s notable written works include The Philosophical Writings of Niels Bohr (1931) and Atomic Physics and Human Knowledge (1961.)

In 1954, Bohr helped establish CERN, the European particle physics facility. His son, Aage Niels Bohr (1922–2009,) was also an atomic physicist nucleus and a winner of the 1975 Nobel Prize in Physics.
