Niels Bohr Biography

Niels Bohr (Niels Bohr) is one of the most important scientists of modern physics, known for his important contributions to quantum theory and the Nobel Prize for the study of atomic structure. 

Niels Henrik David Bohr was born in 1885, Copenhagen. His father was a science professor at the University of Copenhagen, and the Nobel Prize went to Christian Boer and Ellen Adler Bohr, wealthy Hispanics known for their Danish banks. And the Jewish family of the Parliamentary Circle. Bohr received his doctorate from the University of Copenhagen in 1911 and then studied with Ernest Rutherford at Victoria University in Manchester, England.

Niels Bohr was a highly successful scientist and he had proposed revolutionary theories about atomic structure and radiation emission. His idea won the Nobel Prize in Physics in 1922. Many years later, after participating in the Manhattan Project in the United States, he called for the responsible and peaceful application of atomic energy around the world.

Niels Bohr biography will help us in studying about Niels Bohr Discovery in parallel with his personal life and achievements.

Bohr Scientist Early Life:

Niels Bohr Education: 

Niels Bohr Scientist was born in Copenhagen, Denmark, on October 7, 1885. His mother, Ellen Adler, was a member of the successful Jewish banking family, and his father, Christian Bohr was also a famous physiologist. The young Bohr ultimately pursued his education at the University of Copenhagen, where he received a master's and a doctorate in physics in 1911. In the autumn of the same year, Bohr went to Cambridge, England, where he was able to follow the scientist J.J. Thomson. 

Bohr and his wife Margaret had six children, one of them was Aage Niels Bohr (Aage Niels Bohr), who became a highly successful physicist and won the Nobel Prize. Bohr died in Copenhagen in 1962. The Bohr element is named after him.

Bohr's own research or (Niels Bohr information) led him to theorize in a series of papers that based on the model previously held by Ernest Rutherford, atoms emit electromagnetic light radiation of fixed wavelength as a result of electrons exciting to different orbital levels. Although Niels Bohr discovery will finally be revised by other scientists, his ideas laid the foundation for future atomic research.

After teaching at the Victoria University of Manchester, Bohr once again settled at the University of Copenhagen in 1916 as a faculty member. Then, in 1920, he founded the University's Institute of Theoretical Physics, where he will spend the rest of his life.

Neils Bohr work:

In 1911, Bohr visited Cambridge, where he followed the experimental work of Sir J.J. at the Cavendish Laboratory. Under Thomson's direction, he conducted his own theoretical research.

In 1912, Niels Bohr started working in Professor Rutherford's laboratory in Manchester. With reference to Rutherford's theory, Bohr published his model of atomic structure in 1913, which is still widely used today and taught as a simplification of education. Bohr's invention of this atomic model introduces the theory that electrons move in orbits around the nucleus and the chemical properties of the elements are highly dependent on the number of electrons in the outer orbit. Bohr also introduced the idea that electrons can descend from higher energy orbits to lower orbits, emitting discrete energy photons (photons). Afterwards, this concept became the foundation of quantum principles.

Following in his father's footsteps, Bohr became a professor at the University of Copenhagen in 1916. In 1920, he became director of the newly created "Institute for Theoretical Physics", and in 1922 he won the Nobel Prize in Physics for his " contribution to the study of atomic structure and atomic radiation ".

After 1930, Bohr's activities at his institute focused on studying the composition of the nucleus and its evolution and disintegration. He also contributed to elucidate the problems encountered in quantum physics, which were discussed in various articles written between 1933 and 1962.

The Nobel Prize:

Bohr was honoured with the Nobel Prize in Physics in 1922 (Bohr year of discovery) for his work on atomic structure, and he will continue to put forward revolutionary theories. He collaborated with Werner Heisenberg and other scientists to study the new principles of quantum mechanics related to Bohr's concept of complementarity, which was first proposed at the Italian Conference in 1927. The concept claims that the physical properties at the atomic level will vary from experiment to experiment, which explains why light can be viewed as particles and waves, even though they will never exist at the same time. 

Bohr also began to apply this idea in philosophy, and he believed that the constantly evolving concepts of physics had profoundly influenced the views of mankind. Another physicist named Albert Einstein disagreed with all of Bohr's claims, and his speech was widely known in the scientific community.

Bohr continued to collaborate with a team of scientists at the forefront of nuclear fission research in the late 1930s, for which he contributed the droplet theory. In addition to his pioneering ideas, Bohr is also known for his wit and enthusiasm, and his humanitarian ethics influenced his later work.

Bohr received numerous honours and praises. In addition to the Nobel Prize, he also received the Hughes Medal in 1921, the Matt Uchi Medal in 1923, the Franklin Medal in 1926, the Copley Medal in 1938, the Elephant Medal in 1947, and the 1947 Atomic Peace Award. The Sonning prizes in 1957 and 1961. He became a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1923, and in 1926 he became a foreign member of the Royal Society. 

Escape From Europe:

With the coming to power of Adolf Hitler, Bohr was able to provide asylum for German Jewish physicists at his Copenhagen institute, which in turn brought many people to the United States. After Denmark was occupied by Nazi forces, the Bohr family fled to Sweden, and Bohr and his son Ogg eventually left for the United States.

Bohr later worked with the Manhattan Project in Los Alamos, New Mexico, where the first atomic bomb was being built. Because he was concerned about how to use the bombs, he called for future international arms control and active communication between nations on weapons, an idea that Winston Churchill and Franklin D. Roosevelt resisted.

Atoms for Peace: 

After the war, Bohr returned to Europe and continued to call for the peaceful use of atomic energy. In the "Open Letter to the United Nations" dated June 9, 1950, Bohr envisioned an "open world" pattern of existence between countries that abandoned isolationism to achieve true cultural exchanges.

In 1954, he helped establish CERN, a European research institution for particle physics, and organized the 1955 Atomic Peace Conference. In 1957, Bohr won the Atomic Peace Prize for his pioneering theories and efforts to use atomic energy responsibly.

Neils Bohr Death:

Neils Bohr Scientist was a prolific writer and has published more than 100 publications under his name. After a stroke, he died in Copenhagen on November 18, 1962. Bohr's son Aage shared the 1975 Nobel Prize in Physics with the other two in recognition of his research on nuclear motion.

Conclusion:

• Niels Henrik David Bohr (October 7, 1885-November 18, 1962) was a Danish scientist who made fundamental contributions to the understanding of the atomic structure and quantum theory and obtained The Nobel Prize in Physics in 1922. Neils Bohr scientist was not only a scientific researcher but also a great philosopher and promoter of scientific research. 

• Bohr developed Bohr’s atomic model, in which he proposed that the energy levels of electrons are discrete, and the electrons rotate on a stable orbit around the nucleus but can transition from one energy level (or orbit) to another Energy level (or orbit). 

• Although the Bohr model has been replaced by other models, its basic principles are still valid. He conceived the principle of complementarity: elements can be individually analyzed based on contradictory characteristics, such as behaving like waves or particle streams. The concept of complementarity dominates Bohr's thinking in science and philosophy. 

• The Institute of Theoretical Physics at the University of Copenhagen was founded by Neils Bohr scientist, now called the Niels Bohr Institute, which was established in 1920. Bohr conducted guidance and cooperation with physicists such as Hans Kramer, Oscar Klein, George de Hervisi, and Werner Heisenberg. He predicted the existence of a new element similar to zirconium, which was named hafnium, named after the Latin name of Copenhagen, and was discovered there. 

• Bohr received numerous honours and praises. He was awarded the honourable Nobel Prize in physics for Niels Bohr Discovery of atomic theories.

• On November 21, 1963, Denmark issued a stamp to commemorate the 500th anniversary of the Bohr model, which represents the Bohr formula, the hydrogen atom, and the energy level difference between any two hydrogens. 

• Bohr died of a heart attack at his home in Carlsberg on November 18, 1962. He was cremated and his ashes were buried with his parents, Harald brothers and Christian son in a family cemetery at Assistens Cemetery in the Norrebro district in Copenhagen. Years later, his wife's ashes were also buried there.

• On 7 October 1965, to commemorate the 80th anniversary of its founding, the Institute of Theoretical Physics of the University of Copenhagen officially changed its name to Niels Bohr Institute.
