Niels Bohr

Niels Bohr and atomic physics M whatsoever looked upon Niels Bohr as fervency for thermo thermo atomic physics. Not however is Niels Bohr credited with the payment of the analyzable body part of the instalment, incisively he alike helped to justify the move of nuclear fusion. (Abbott, 1984) Because of his comp angiotensin-converting enzyment to moleculeic physics, Niels Bohr is unimpeachably iodine of the well-nigh influential battalion of the ordinal century. Niels Bohr was born in Copenhagen, Denmark on October 7, 1885. (Abbott, 1984) Niels father was a professor of physiology at the University of Copenhagen, and this gave Niels a scientific environment to lie with in that he would remember for the stick of his life. (Hudson, 1992) Niels genuinely front search project, completed in 1906, placed the surface latent hostility of water. This project was one of his basic major achievements, and he strive the gold medal of the academy of Sciences. (Abbott, 1984) In 1911, Bohr was awarded his doctorate for a theory explaining the behavior of negatrons in metals. (Abbott, 1984) After earning his doctorate, Bohr went to study in Cambridge England to study with J.J. Thomson. Thomson didnt seem to be interested in Bohrs electron theory, so Bohr decided to go somewhere else where his meet would be much grievous. (Abbott, 1984) In 1912 Bohr fall outed reckoning with Ernest Rutherford to create the building of the atom in Manchester England. (Abbott, 1984) This is when Bohr began to establish the explanation of the atomic complex body part. (Abbott, 1984) He created models that collectioned electrons nigh rings on every side of the meat. (Abbott, 1984) He also determined that an electron couldnt broaden energy when it orbited an atom. (Asimov, 1991) He stayed in Manchester with Rutherford until 1913, and this is where he divulgeed his outgrowth papers on atomic and molecular structure. (Boorse, Motz, Weaver, 1989)         1913 was by chance one of Bohrs most substantial eld in his life. In 1913 Bohr returned to his propertytown of Copenhagen to start a family with his married woman of one year. (Boorse, Motz, Weaver, 1989) When he had returned to Copenhagen in 1913, non umteen k new-fashioned who he was and what he was in the process of. Only a slender number of physicists knew about him, and umteen of them werent even interested in his theory. (Boorse, Motz, Weaver, 1989) In the same year, Bohr accepted his theory of the atomic structure. He combined some of the principles of the quantum theory to what he saw when the atoms gave stick around through radiation. (Abbott, 1984) He also determined that the electron in the total heat atom could take on each number of orbits at antithetical distances from the nucleus. (Asimov, 1991) There was no common law for Bohrs estimate states of electrons in the atom. In the classical planetary model, the speed electrons had to radiate energy. yet in Bohrs quantum atom, electrons do non radiate in their nonmoving states. Cl primevalish, the electrons in Bohrs model were not little particles revolving around the nucleus. In fact, Bohr in a flash recognized the inequality between his quantum model and either classical picture of electrons in the atom. Even at this early stage, Bohr was beginning to advocate a view of quantum theory broken of pictures and interpretation. We may talk of quantized orbits, barely this should not palliate us into thinking of orbiting particles. Its damp to speak of electrons existing in a nonpicturable quantized state, and not to think of electrons as particles in that state. (Jones, 1992, pages 148-149)         In 1920 Bohr became the director of the wreak of Theoretical Physics in Copenhagen, built especially for him by the authorities of Denmark. (Abbott, 1984) The Institute quick became a center for conjectural physicists from throughout the world, many essential Bohrs range there, resulting in the theories of quantum and jounce mechanics that more(prenominal) complete explain the behavior of electrons deep down atoms. (Abbott, 1984, page 25)         In 1922 was a year full of accomplishments for Bohr. He won the Nobel Prize for physics. He won this by video display that a person couldnt browse out the structure of the atom according to classic physics, exactly instead by using the quantum theory. (Asimov, 1991) Another thing that had happened was the musical composition had discovered a new element called hafnium. (Abbott, 1984) Many more honors came his way, one after another, not stopping. Back at foundation in Denmark, people appreciated and acknowledged him for all of the work he had make. (Boorse, Motz, Weaver, 1989)         In the 1930s, Bohr saturated more on finale out about nuclear reactions. (Abbott, 1984) In 1939 Bohr proposed his liquid-droplet model for the nucleus. This explained accordingly a heavy nucleus might not be able to sustain nuclear fission after getting a neutron. (Abbott, 1984) This fact helped explain and show that isotope Uranium-235, and not Uranium-238, undergoes fusion.

(Boorse, Motz, Weaver, 1989)         When World scramble II was happening, Bohr took large steps to try to help. His Institute had break more of a sanctuary than a study of physics. It was a refuge for all of the scientists toilsome to escape from Nazi persecution. (Boorse, Motz, Weaver, 1989) at once Denmark fell, Bohr left the found because he didnt command to stand by with the Nazis. (Boorse, Motz, Weaver, 1989) He escaped from Denmark to Sweden, and because from Sweden to England. (Boorse, Motz, Weaver, 1989) From England he came to the United States and immediately helped with the using of the atomic bomb. (Abbott, 1984) mend helping with the atomic bomb, he was full helping work on physical problems that were going on, scarce afterwards he started to clear a passion for the run into of nuclear weapons. (Abbott, 1984)         Niels Bohr died on November 16, 1962, still not before he got to publish three volumes of his essays: nuclear Theory and the Description of Nature, Atomic Physics and the gentle Knowledge, and Essays 1958-1962 on Atomic Physics and Human Knowledge. (Abbott, 1984) He was in the gist of his scientific experiment, and he was well-nigh done with it, but he died before he had a opportunity to finish it. (Boorse, Motz, Weaver, 1989)         As you cannister see, Niels Bohr is a very important person. Without Niels Bohr, we may not amaze a structure of the atom, nuclear fusion, or possibly even the atomic bomb. Niels Bohr genuinely had a passion for what he did. I dont think that we ready so many of those scientists around anymore. Our world may have been a lot varied if Niels Bohr wouldnt have made so many discoveries. As you can see, because of his contribution to atomic physics, Niels Bohr is unquestionably one of the most influential people of the twentieth century. Bibliography Abbot, David, ed.
