Niels Bohr

Niels Bohr, the renowned physicist known for his contributions to the understanding of atomic structure, was born on October 7, 1885.

Harald Bohr, the brother of Niels Bohr, is born on April 22, 1887, in Copenhagen, Denmark.

Christian Bohr, father of Niels Bohr, was nominated for the Nobel Prize twice during the period of 1903 to 1911.

In 1907, Niels Bohr's thesis on the determination of surface tension through vibrations of water jets earned him a gold medal from the Royal Danish Academy of Science. This early recognition marked the beginning of his influential career in physics.

Niels Bohr obtained his Master's degree in Physics in 1909.

Niels Bohr obtained his doctorate in 1911 with a dissertation on the electron theory of metals.

On June 29, 1912, Niels Bohr married Margrethe Nørlund, who became an ideal companion for him. They went on to have six sons, but tragically lost two of them.

On August 1, 1912, Niels Bohr married Margrethe Nørlund, and the marriage proved a particularly happy one. Throughout his life, Margrethe was his most-trusted adviser.

In December 17, 1912, Niels Bohr made significant progress in the development of his atomic model, which revolutionized the understanding of atomic structure.

Niels Bohr's successful calculations of spectral line positions in 1913 using quantum theory helped solidify its acceptance in the scientific community. This work demonstrated the practical applications of quantum theory in explaining atomic phenomena.

Niels Bohr proposed the planetary model of the atom, also known as the Bohr Model, which describes the movement of electrons in specific energy levels and the production of spectrum lines when electrons move.

In 1914, Niels Bohr joined Ernest Rutherford's research group, a pivotal collaboration that led to groundbreaking discoveries in nuclear physics.

On March 3, 1921, Niels Bohr inaugurated his Institute for Theoretical Physics at the University of Copenhagen, emphasizing the importance of experiments and experimenters at the institute, as well as his ambition to make it a place for the younger generation of physicists to propose fresh ideas.

In 1920, Niels Bohr was appointed as a professor of theoretical physics, solidifying his influential role in the academic and scientific community.

On March 3, 1921, Bohr's Institute was established, which played a significant role in the development of quantum mechanics and atomic physics.

Niels Bohr founded the field of quantum mechanics, which revolutionized the understanding of the behavior of particles at the atomic and subatomic levels.

Niels Bohr was awarded the Nobel Prize in Physics in 1922 for his work on the structure of atoms and the emission and absorption of energy by electrons.

In 1924, Nobel Prize-winning physicist Niels Bohr gives two lectures at Harvard, which inspires Oppenheimer to idolize him. A college friend describes Oppenheimer's admiration by saying 'Niels Bohr was God, and Oppie was his prophet'.

Niels Bohr and his family were forced to flee Copenhagen in 1943 due to the threat posed by the Nazis because of their Jewish heritage. They sought refuge in England and later moved to the United States, where they became involved in the Manhattan Project.

In 1950, Niels Bohr penned an open letter to the United Nations, urging international collaboration and ethical considerations in the realm of nuclear technology and global security.

In 1954, Niels Bohr became involved with the establishment of CERN, the European Organization for Nuclear Research, contributing to advancements in particle physics and international scientific cooperation.

Niels Bohr was honored with the United States Atoms for Peace Award in 1957 for his efforts in promoting world peace and advocating for international cooperation in controlling weapons of mass destruction.

Niels Bohr, the Nobel Prize-winning physicist and pioneer of quantum theory, passed away on November 18, 1962.
