Niels Bohr was a prominent Danish physicist known for his contributions to quantum theory and atomic structure. He was born on October 7, 1885, in Copenhagen, Denmark. Bohr's father was a professor of physiology, which influenced his interest in science from an early age. Bohr studied physics at the University of Copenhagen and earned his doctorate in 1911. After completing his studies, he traveled to England, where he worked with [[J.J. Thomson]] at the Cavendish Laboratory in Cambridge. During this time, he became familiar with the latest developments in atomic physics. In 1913, Bohr proposed his groundbreaking atomic model known as the "Bohr model." Based on quantum theory principles proposed by [[Max Planck]] and [[Albert Einstein]], Bohr's model explained that electrons exist in specific energy levels or orbits around the nucleus of an atom. This model revolutionized our understanding of atomic structure and provided a foundation for further advancements in quantum mechanics. Bohr's work on the structure of atoms led to his development of the concept of complementarity, which he presented in his famous "Copenhagen interpretation" of quantum mechanics. Complementarity suggests that particles can exhibit both wave-like and particle-like properties depending on how they are observed. During World War II, Bohr fled Denmark due to his Jewish heritage and worked on the Manhattan Project in the United States. He contributed to the development of nuclear weapons but later became a strong advocate for peaceful use of atomic energy. After the war, Bohr returned to Denmark and became heavily involved in promoting international cooperation and peaceful use of nuclear energy. He established the Niels Bohr Institute for Theoretical Physics at the University of Copenhagen, where many prominent physicists conducted research. Niels Bohr received numerous awards and honors throughout his career for his contributions to science. In 1922, he was awarded the Nobel Prize in Physics for his investigations into the structure of atoms and the radiation they emit. He continued to work and inspire future generations of physicists until his death on November 18, 1962, in Copenhagen. Bohr's ideas and theories continue to have a profound impact on our understanding of quantum mechanics and atomic physics. His contributions laid the foundation for modern physics, and his legacy as one of the most influential physicists of the 20th century remains significant. # References ```dataview Table title as Title, authors as Authors where contains(subject, "Niels Bohr") or contains(authors, "Niels Bohr") ```
