Biography of Niels Bohr, The Danish Physicist Essay

Harald became the first of the Bohr brothers to earn a master’s degree. Niels earned his 9 months later. The students in his class had to submit a thesis on a subject assigned by their supervisor. Bohr’s supervisor was Christiansen, and the topic he gave them was the electron theory of metals. Bohr then elaborated his master’s thesis in to his much larger theory â€Å"Doctor of Philosophy† thesis. He questioned the literature on the subject ,settling on a model assumed by Paul Drude and elaborated by Hendrik Lorentz ,which stated in which the electrons on a meta; are considered to behave like a gas. Bohr enlarged Lorentz model, but still unable to account for singularities like the Hall Effect, and decided that the electron theory could not†¦show more content†¦His 3 papers, which later became famous as the â€Å"trilogy â€Å"were published in the Philosophical magazine in July. Later in the year He revised Rutherford’s nuclear structure to Max Planck’s quantum theory and created the Bohr model of the atom. He revolutionized the theory of electrons traveling in orbits around the atoms nucleus. He also announced the idea that an electron could drop from a higher energy orbit to a lower one, in the progress also emitting a quantum of discrete energy. This theory became known as the old quantum theory. The trilogy’s acceptance was dur to it s ability to explain the phenomena which blocked other models ,and predicted the results that were then verified by experiments. Today the Bohr model of the atom has been outdated but is still known as the best model of atoms, and is still used in high school physics and chemistry. Bohr soon realized that he did not enjoy teaching the medical students. He decided to return to Manchester, where Rutherford had offered him a job as a reader in Darwin’s place, whose contract had expired, Bohr accepted. In April 1917, Bohr began a campaign to establish an institute of Theoretical Physics. He gained the support of Danish government and Carlsberg Foundation, establishing the institution in November 1918 known as the Niels Bohr Institute, the doors were opened by March 3,1921 with Bohr as the director. His family moved into an apartment on the first floor. The Bohr Institute helped as a main point forShow MoreRelatedThe Physics Of The Atomic Theory1519 Words   |  7 Pages In the early 1800s, scientist John Dalton began studying various gases. He soon came to realize that gases were actually made up of individual particles and were not a chemical solvent, as previously thought by other scientists (John Dalton Biography). After further experimentation, Dalto n felt confident in his assumption that all types of matter were also made of individual particles. Dalton named these particles â€Å"atoms,† which he borrowed from Democritus’s original theory. In 1803, he officially
