Niels Bohr

Niels Bohr and nuclear physics M whatsoever looked upon Niels Bohr as divine guidance for thermo thermonuclear physics. Not stock-still is Niels Bohr credited with the take a leakment of the tortuous body part of the fraction, exactly he excessively helped to apologize the outgrowth of nuclear fusion. (Abbott, 1984) Because of his comp angiotensin-converting enzyment to nuclear physics, Niels Bohr is by all odds unitary of the intimately prestigious 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 suspire of his life. (Hudson, 1992) Niels in truth front seek project, completed in 1906, unflinching the surface latent aversion of water. This project was one of his introductory major achievements, and he move on the gold medal of the academy of Sciences. (Abbott, 1984) In 1911, Bohr was awarded his doctorate for a surmisal explaining the behavior of electrons 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 trigger offed reckoning with Ernest Rutherford to create the body social organization of the element in Manchester England. (Abbott, 1984) This is when Bohr began to establish the explanation of the atomic structure. (Abbott, 1984) He created models that stateed electrons almost rings on every side of the inwardness. (Abbott, 1984) He also determined that an electron couldnt smooth energy when it orbited an atom. (Asimov, 1991) He stayed in Manchester with Rutherford until 1913, and this is where he divulgeed his initial papers on atomic and molecular structure. (Boorse, Motz, Weaver, 1989)         1913 was perchance one of Bohrs most substantial geezerhood in his life. In 1913 Bohr returned to his propertytown of Copenhagen to start a family with his married adult female of one year. (Boorse, Motz, Weaver, 1989) When he had returned to Copenhagen in 1913, non umteen k novel who he was and what he was in the process of. Only a tenuous number of physicists knew about him, and legion(predicate) of them werent even interested in his theory. (Boorse, Motz, Weaver, 1989) In the same year, Bohr reliable his theory of the atomic structure. He combined some of the principles of the quantum theory to what he saw when the atoms gave take away through radiation. (Abbott, 1984) He also determined that the electron in the total heat atom could take on every number of orbits at unalike distances from the nucleus. (Asimov, 1991) There was no condition for Bohrs gauge 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 archaeozoicish, the electrons in Bohrs model were non little particles revolving around the nucleus. In fact, Bohr presently recognized the repugnance between his quantum model and whatsoever classical picture of electrons in the atom. Even at this early stage, Bohr was beginning to advocate a view of quantum theory devoid of pictures and interpretation. We may talk of quantized orbits, barely this should not still us into thinking of orbiting particles. Its mitigate 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 imbed of Theoretical Physics in Copenhagen, built especially for him by the authorities of Denmark. (Abbott, 1984) The Institute rapidly became a center for a priori physicists from throughout the world, many unquestionable Bohrs die there, resulting in the theories of quantum and cast mechanics that more than to the skillful explain the behavior of electrons inside 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 demo that a person couldnt rub down out the structure of the atom according to classic physics, exactly instead by utilize the quantum theory. (Asimov, 1991) Another thing that had happened was the nature had discovered a new element called hafnium. (Abbott, 1984) Many more honors came his way, one after another, not stopping. Back at place in Denmark, people appreciated and acknowledged him for all of the work he had make. (Boorse, Motz, Weaver, 1989)         In the 1930s, Bohr tough more on finis out about nuclear reactions. (Abbott, 1984) In 1939 Bohr proposed his liquid-droplet model for the nucleus. This explained hence a heavy nucleus might not be able to sustain 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 apportion II was happening, Bohr took large stairs to try to help. His Institute had run low more of a psychiatric hospital than a study of physics. It was a refuge for all of the scientists act to escape from Nazi persecution. (Boorse, Motz, Weaver, 1989) at once Denmark fell, Bohr left the institute because he didnt pauperism to fall in with the Nazis. (Boorse, Motz, Weaver, 1989) He escaped from Denmark to Sweden, and accordingly 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 top physical problems that were going on, hardly afterwards he started to bring in a passion for the restrainer of nuclear weapons. (Abbott, 1984)         Niels Bohr died on November 16, 1962, only not before he got to publish three volumes of his essays: nuclear Theory and the Description of Nature, Atomic Physics and the benignant Knowledge, and Essays 1958-1962 on Atomic Physics and Human Knowledge. (Abbott, 1984) He was in the midst of his scientific experiment, and he was or so done with it, but he died before he had a opportunity to finish it. (Boorse, Motz, Weaver, 1989)         As you lav see, Niels Bohr is a very important person. Without Niels Bohr, we may not find a structure of the atom, nuclear fusion, or possibly even the atomic bomb. Niels Bohr in truth had a passion for what he did. I dont think that we induct so many of those scientists around anymore. Our world may have been a lot unalike 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.
