Albert Einstien Essays - Albert Einstein, Theory Of Relativity

Albert Einstien Men and Women of Science Albert Einstein Early Life Einstein was born in Ulm, Germany on Mar. 14, 1879. Einstein's parents, who were non observant Jews, moved from Ulm to Munich, Germany when Einstein was an infant. The family business was the manufacture of electrical parts. When the business failed, in 1894, the family moved to Milan, Italy. At this time Einstein decided officially to end his German citizenship. Within a year, still without having completed secondary school, Einstein failed an examination that would have allowed him to pursue a course of study leading to a diploma as an electrical engineer at the Swiss Federal Institute of Technology. He spent the next year in nearby Aarau at the cantonal secondary school, where he enjoyed excellent teachers and first-rate facilities in physics. Einstein returned in 1896 to the Swiss Federal Institute of Technology, where he graduated, in 1900 as a secondary school teacher of mathematics and physics. After two years he obtained a post at the Swiss patent office in Bern. The patent-office work required Einstein's careful attention, but while employed (1902-1909) there, he completed an astonishing range of publications in theoretical physics. For the most part these texts were written in his spare time and without the benefit of close contact with either the scientific literature or theoretician colleagues. Einstein submitted one of his scientific papers to the University of Zurich to obtain a Ph.D. degree in 1905. In 1908 he sent a second paper to the University of Bern and became a lecturer there. The next year Einstein received a regular appointment as associate professor of physics at the University of Zurich. By 1909, Einstein was recognized throughout German-speaking Europe as a leading scientific thinker. In quick succession he held professorships at the German University of Prague and at the Swiss Federal Institute of Technology. In 1914 he advanced to the most prestigious and best-paying post that a theoretical physicist could hold in central Europe, professor at the Kaiser-Wilhelm Gesellschaft in Berlin. The 1905 papers In the first of three papers that were published in 1905, Einstein examined the phenomenon discovered by Max Planck, according to which electromagnetic energy seemed to be emitted from radiating objects in quantities that were ultimately discrete. The energy of these emitted quantities, the so-called light-quanta was directly proportional to the frequency of the radiation. This circumstance was perplexing because classical electromagnetic theory, based on Maxwell's equations and the laws of thermodynamics, had assumed that electromagnetic energy consisted of waves propagating in a hypothetical, all-pervasive medium called the luminiferous ether, and that the waves could contain any amount of energy no matter how small. Einstein used Planck's quantum hypothesis to describe visible electromagnetic radiation, or light. According to Einstein's resourceful viewpoint, light could be imagined to consist of discrete bundles of radiation. Einstein used this interpretation to explain the photo electric effect, by which certain metals emit electrons when illuminated by light with a given frequency. Einstein's theory, and his subsequent elaboration of it, formed the basis for much of quantum mechanics. The second of Einstein's 1905 papers proposed what is today called the special theory of relativity. At the time Einstein knew that, according to Hendrik Antoon Lorentz's theory of electrons, the mass of an electron increased as the velocity of the electron approached the velocity of light. Einstein also knew that the electron theory, based on Maxwell's equations, carried along with it the assumption of a luminiferous ether, but that attempts to detect the physical properties of the ether had not succeeded. Einstein realized that the equations describing the motion of an electron in fact could describe the nonaccelerated motion of any particle or any suitably defined rigid body. He based his new kinematics on a reinterpretation of the classical principle of relativity, that the laws of physics had to have the same form in any frame of reference. As a second fundamental hypothesis, Einstein assumed that the speed of light remained constant in all frames of reference, as required by cl assical Maxwellian theory. Einstein abandoned the hypothesis of the ether, for it played no role in his kinematics or in his reinterpretation of Lorentz's theory of electrons. As a consequence of his theory Einstein recovered the phenomenon of time dilatation,

Daydreaming is Better Than Reality Essays - English-language Films Daydreaming is Better Than Reality Dorian Raines Dr. Xie English 1013-06 Essay 2 March 26, 2014 Daydreaming is Better Than Reality The main character from "Death of a Salesman", Willy, really had a hard time with the real world, and had thoughts of everything that he went through in the past. During the whole play from beginning to end Willy is confused and does not pay any attention to what is going on around him in the real world. With him dreaming everyday and having these crazy illusions he is beginning to think that things could possible brighten up his life a little and make things better. Him thinking things would get better would make him think about old times in his life, when he had his whole family to make him happy, and we had a job that brought in good money for the whole household. Willy was so deep in his daydreams sometimes it was hard for him to realize that the life he was living was not the one that he wanted it to be. Willy thinking that his life was perfect and he didn't have any problems really hurt his family because they had to suffer from the things that he was forgetting about. Willy wo uld often have outburst of anger and go crazy on his dearest friends and family. The only thing that seemed to calm Willy down was daydreaming about what he thought was reality. In the beginning of Act 1 Willy is very confused and doesn't really know reality from his daydreams. Willy sons Happy and Biff, Biff was the oldest, and was criticized for working the manual labor job at farms and different ranches. When Biff gets of work he really lets his mind roam and doesn't know what he things about but he really lets his mind wonder. Willy states that his son is lazy, but later in the story this changes and says that his soon is anything but lazy. During the whole play Willy has a confusion of his words and says something and later says the complete opposite. Willy's other son Happy is the more successful one out of the two siblings, and the father and son bond is close to nothing. Willy seems to blame himself for the way his son Biff is turning out, almost a failure getting in and out of jobs since he has been out of high school. He really blames himself because when Happy and Biff were at younger ages he didn't really speak on how important success was. All t hrough the play Willy thinks about when his kids were smaller and had borrow stuff to practice for different sports and things that they wanted to play. From different context clues shows that Biff was well liked and was an athlete but he had a lot of problems in math class. Willy assumes that just because a person is well liked that they will automatically be successful. Coming back to the real world, Willy craved attention from everybody even though he a family and a woman on the side he still feels that he needed more. The woman on the side never really was announced by named but she appears in one of his daydreams that he usually had throughout the day. In the dream he was caught fooling around with the other woman in a hotel room, one thing he would do for this mystery lady is buy her new stockings even before he thought about his wife. Things turn around in the play when Willy's son Biff finds out what is going on with his father and this outside woman in his fathers life. Biff really took a turn in education when he found this out it really had an impact on the way he thought about school. Linda would really like Willy to stay somewhere close and do his work because she is worried about him being away with his brother. Willy goes behind everyone's back and tries to get the job away from home but gets denied by his boss. In Act 2, everything really begins to go down hill it starts with Willy getting fired from his job. Willy's boss says that he doesn't
