   Extractions: related subjects Achievement Biography Niels Bohr was born and educated in Copenhagen, Denmark. He lived, worked, and died there, too. But his mark on science and history was worldwide. His professional work and personal convictions were part of the larger stories of the century. At the University of Copenhagen, he studied physics and played soccer (though not as well as his brother, who helped the 1908 Danish soccer team win an Olympic silver medal). After receiving his doctorate in 1911, Bohr traveled to England on a study grant and worked under J.J. Thomson, who had discovered the electron 15 years earlier. Bohr began to work on the problem of the atom's structure. Ernest Rutherford had recently suggested the atom had a miniature, dense nucleus surrounded by a cloud of nearly weightless electrons. There were a few problems with the model, however. For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck In 1912 Bohr married Margrethe Nørlund. They had six sons, one of whom, Aage, followed his father into physics and into the ranks of Nobel Prize-winners. Bohr returned to Denmark as a professor at the University of Copenhagen, and in 1920 founded the Institute for Theoretical Physics sponsored by the Carlsberg brewery! Bohr remained director of the institute for the rest of his life, except for his absence during World War II. Bohr's personal warmth, good humor ("Never express yourself more clearly than you can think," he once said), and hospitality combined with world events to make Copenhagen a refuge for many of the century's greatest physicists.

   Extractions: Died: 18 Nov 1962 in Copenhagen, Denmark Niels Bohr 's father was Christian Bohr and his mother was Ellen Adler. Christian Bohr was awarded a doctorate in physiology from the University of Copenhagen in 1880 and in 1881 he became a Privatdozent at the university. Late in the same year he married Ellen, who was the daughter of David Adler, a Jewish politician with a high standing in Danish political and commercial life. Christian and Ellen had three children. The eldest was Jenny born in 1883 in the mansion which David Adler had owned opposite Christiansborg Castle where the Danish Parliament sat. Ellen's mother had continued to live in this house after her husband David Adler died in 1878 and Ellen had gone back to her mother's home to have her child. Two years later Niels was born on his mother's 25 th birthday in the same stately home, Ellen again having returned to her mother's house for the birth of her child. The third child of the family, who went on to become a famous mathematician, was Harald Bohr who was two years younger than Niels. When Niels was only a few months old his father Christian had been appointed as a lecturer to fill a post left vacant by the death of Peter Panum, the professor of physiology at the University of Copenhagen, and a short while later the family moved into the Panum's professorial house in Copenhagen.

    Extractions: From the end of World War two the main focus of nuclear weapons had been on power and deterrence. Back in 1944 the Danish nuclear scientist Niels Bohr (1885-1962) recommended to the UK Prime Minister Winston Churchill the establishment of international control over the use of nuclear weapons. Shortly before the beginning of the Korean war June 9, 1950 Bohr wrote an open letter to the United Nations, because In the middle of the 1950s the general view on nuclear weapons policy changed with growing concern over health and environmental damages caused by atmospheric nuclear weapons tests . The Einstein-Russell-appeal of 1955 saw the creation of many campaigns for nuclear disarmament. Inspired by England the Danish Campaign against Nuclear Weapons was created in January 1960 by members of the Danish chapter of the WRI. Late summer 1960 also saw the creation of the Union of Cathollic Workers Action By the parliamentarian election of 1964, the nuclear pacifists were so strong, that a new liberal

It's used all the time in calc and I don't understand what it represents or it's value. Thanks (can we ignore the "infinite number of decimals" thing - that's neither here nor there, as well as incorrect English 1/3 has also not a finitely long decimal expansion in base 10, and? And there were no rational transcendental numbers. A number is transcendental if it is not a root of any polynomial with integer (whole number) coefficients.The complementary notion is 'algebraic'; all integers are algebraic, sqrt(2) is algebraic, pi isn't.) I, e, t arises as the (unique) solution to f'=f, which tells you that it is important in "the real world" since we model that with differential equations, and importantly, once we've defined e, we can solve f'=kf, as well as a whole load of other differential equations without needing to define anything else.

    Extractions: Born in Copenhagen to Christian Bohr and Ellen Adler, Bohr received his doctorate from Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his model of atomic structure in 1913, introducing the theory of electrons travelling in orbits around the atom's nucleus, the chemical properties of the element being largely determined by the number of electrons in the outer orbits. Bohr also introduced the idea that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy. This became the basis for quantum theory.

    Extractions: Niels Henrik David Bohr was born on October 7, 1885 in Copenhagen, Denmark. He died in Copenhagen on November 18, 1962 as a result of a stroke. His father, Christian bohr, a very well known physiologist, and mother Ellen recognized the abilities that he held very early in his life. From that early age they gave Niels the best education they could. Bohr began attending Copenhagen University in 1903. Besides studying physics, he was a member of the Copenhagen soccer team. He was good at soccer, but not as good as his brother, who helped the Danish soccer team win a silver medal at the 1908 Olympics. bohr got his Masters degree in physics in 1909, and went on to receive his doctorate in 1911. He then went on to study at Cambridge with Sir J.J. Thomson , who had discovered the atom 15 years earlier. Unfortunately, his ideas conflicted with those of Thomson and he soon decided to move to Manchester in 1912 to study under Ernest Rutherford In 1913, Bohr published his first theory on the structure of the atom. This was an extensiion of Rutherford's theory, which said that electrons orbited the nucleus of an atom. Bohr's theory stated that these electrons occupied strict energy levels within the atom. Other physiciists eventually expanded this theory into quantum mechanics. Bohr married Margrethe Norlund in 1912. The two had six sons, one of whom, Aage, followed his father's footsteps into physics and eventually won his own Nobel Prize in 1975.
