    have restrictions on where the electron cannot go, eventually it would run out of energy to give off, causing it to spiral inwardly towards the nucleus. Now we know that this idea of an unstable atom is not true, otherwise we would not be here today. Therefore this model must be altered to fit our new understanding of the structure of the atom. This is where Niels Bohr’s Bohr Model comes into play. Unlike Rutherford’s Planetary model, the Bohr Model has placed strict restrictions on where the electron can and cannot go. Bohr found that the electrons will travel around the atom at discrete energy levels, never between. He determined that electrons are quantized, which means they are whole number multiples of some unit. The electrons can have quantum leaps between the ground and outermost excited stages. According to the law of conservation of energy, energy cannot be created nor destroyed. Therefore when the electrons are moving from the excited stages towards the ground stage, they are emitting energy in the form of light. The colors emitted are determined by how much energy is being released per quantum leap. Although Niels Bohr 's model helped pave the way for other atomic theories, it was not entirely correct. We will soon learn that electrons do not orbin in a circular motion, we can never know exactly where they are. The most recent model of the atom was introduced by a French physicist named Louis De Broglie. Louis posed a very important question - is it possible for…

    soon after when Ernst Rutherford disproved Thomson’s model with his gold foil experiment. Finally, Niels Bohr built off Rutherford’s gold foil experiment to explain the placement of electrons in an atom. These men and many more all helped pave the way to the modern theory of the atom. Democritus was an ancient philosopher in Greece. Democritus believed that atoms were indivisible and indestructible.…

    Robert Ross, Werner Heisenberg, and Niels Bohr. They all sacrificed, which only lead to suffering for all of them. Although one is a coming of age novel about a WW1 soldier and the other is a play about an imaginary meeting of WWII scientists, both The Wars by Timothy Findley and Copenhagen by Michael Frayn explore the ways in which war affects individuals through the evolution of character, their relationships, and the finale resolution of each text. The evolution of Robert Ross in The Wars…

    Arriving in Copenhagen in the year 1941, Heisenberg is met by Bohr and his wife with hesitation, not open arms. As a result of being on opposite sides of the war, there is clear and apparent tension between the two companions. It can be reasonably inferred that Bohr feels a strong disdain for Heisenberg as Nazism has occupied his homeland Denmark. As Margrethe highlights, “‘Niels! They’ve occupied our country!”’(7). Heisenberg, a German citizen, does not realize to the full extent, how…

    immediately after receiving the prize, he was forced to flee to the United States. His situation was remarkably similar to those of Einstein and Bohr, although he was such an accomplished scientist, he was forced to flee because of Mussolini's’ fascist dictatorship and the alliance with Nazi Germany. Enrico Fermi made it safely to the United States where he worked in New York, then to Chicago. In chicago, Fermi lead a team of scientists to create the first ever controlled nuclear chain reaction…

    In Abraham Pais’s article, “What Happened in Copenhagen?: A Physicist's View and the Playwright's Response,” Pais argues the historical accuracy of Michael Frayn’s 1998 play, Copenhagen. Frayn’s play depicts a meeting that took place in 1941 between prominent physicist Niels Bohr and Werner Heisenberg. The play takes place is the Nazi occupied Denmark, and sheds light on the political issues both men are facing. Following Pais’s dispute regarding small details of the play, Frayn then gives his…

    and molecules into ions. When Thomson went on to examine what would later be called an electron, Rutherford took a closer look at ion-producing radiations. In 1902, he left Cambridge and took up a professorship at McGill University in Montreal. He then met Frederick Soddy and created a theory of radioactivity. In 1907, he returned to England. Rutherford made a very important discovery which is discovered of the total mass of an atom in a nuclear. After that, he came up with the nuclear model. He…
