Niels Bohr (1885–1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum mechanics. He is best known for the Bohr model of the atom, proposed in 1913, which introduced the idea of quantized energy levels for electrons. In this model, electrons orbit the nucleus at specific distances, corresponding to specific energy levels, and can jump between these levels by absorbing or emitting energy in the form of photons.
Bohr received the Nobel Prize in Physics in 1922 for his work in this field. He also contributed to the development of the principles of quantum mechanics, particularly through the concept of complementarity, which states that objects have complementary properties that cannot all be observed or measured simultaneously.
In addition to his work in theoretical physics, Bohr played a significant role in the establishment of the Institute for Theoretical Physics in Copenhagen, which became a major center for research in quantum mechanics. He was also involved in discussions regarding the ethical implications of nuclear energy and weapons during and after World War II.
Bohr's legacy includes numerous scientific contributions and influence on subsequent generations of physicists, and he remains a key figure in the history of modern physics.
