...There are five scientists who helped shape not only atomic theory but also our perspective of the atom. Dalton, Bohr, Rutherford, Planck, and Millikan, each of these scientists contributed to atomic theory in their own way and enhanced our knowledge of the atom. John Dalton is known for his work of gas laws (i.e. Dalton’s law) but also his work to lay the ground work for atomic theory. In the year 1800 Dalton presented a paper which was on the constitution of mixed gasses. This would lead him to develop his gas law and also affect others, such as Charles and Gay-Lussac. This research would also lead him to research atomic weights, which lead to his contribution in 1805. Dalton theorized that elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass and other properties. Atoms cannot be subdivided, created, or destroyed. Atoms of different elements combine in simple whole-number ratios to form chemical compounds. In chemical reactions, atoms are...

...and particle physics. He was awarded the Nobel Prize in Physics in 1932 “for the creation of quantum mechanics". From 1924 to 1927, Heisenberg lectured at the University of Göttingen, and conducted research with Niels Bohr at the University of Copenhagen. It was during this time that the young Heisenberg developed the “matrix mechanics” formulation of quantum mechanics (in collaboration with Max Born and Pascual Jordan). Matrix mechanics was the first complete and correct definition of quantum mechanics, and it extended the Bohr model of atoms by describing how the quantum jumps occur and by interpreting the physical properties of particles as matrices that evolve over time. In 1939, Heisenberg travelled to the United States to visit Samuel Abraham Goudsmit at the University of Michigan, but refused an invitation to emigrate to the United States. Back in Germany, in 1939, shortly after the discovery of nuclear fission, Heisenberg became one of the principal scientists leading research and development in the German nuclear energy project, known as the “Uranium Club”, and he travelled to German-occupied Copenhagen in 1941 to lecture and discuss nuclear research and theoretical physics with Niels Bohr. In 1942, he was asked by the Nazi administration to direct the Uranium Club's research more toward developing nuclear weapons and, when Heisenberg prevaricated, the authority and regulation of the project...

...1]Main articles: Statistical mechanics, thermal fluctuations, and statistical physics Albert Einstein's first paper[88] submitted in 1900 to Annalen der Physik was on capillary attraction. It was published in 1901 with the title "Folgerungen aus den Kapillarität Erscheinungen," which translates as "Conclusions from the capillarity phenomena". Two papers he published in 1902–1903 (thermodynamics) attempted to interpret atomicphenomena from a statistical point of view. These papers were the foundation for the 1905 paper on Brownian motion, which showed that Brownian movement can be construed as firm evidence that molecules exist. His research in 1903 and 1904 was mainly concerned with the effect of finite atomic size on diffusion phenomena.[88] General principles He articulated the principle of relativity. This was understood by Hermann Minkowski to be a generalization of rotational invariance from space to space-time. Other principles postulated by Einstein and later vindicated are the principle of equivalence and the principle of adiabatic invariance of the quantum number. 2] Main article: History of special relativity Einstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as...

...The 20th Century Genius Award Hum/102 October 19, 2011 The 20th Century Genius Award The nominated figure that stands out in my mind as a genius of Western culture would be Albert Einstein. His work and cultural contributions can be classified in both the Age of Modernism and the Age of Pluralism for the 20th Century Genius Award. The following examples will include a synopsis of the life and times of Albert Einstein, A survey of the ideas and works recognizing the reflections of his genius, and an appraisal of his impact on the arts and culture. Albert Einstein was born on March 14, 1879 to Hermann and Pauline Einstein a scientifically minded family, who were non-practicing Jews in Ulm, Wurttemberg Germany. As a child, he was very curious, and lively. Albert attended a Catholic elementary school, and his mother insisted for him to take violin lessons. Although he detested the lessons, and later on decide not to continue with them, he would later on find an appreciation and great comfort in Mozart’s violin sonatas. At the early age of five, Albert was fascinated by complex scientific and mathematical concepts at a very early age. Hermann Einstein shows his son a pocket compass, and Einstein with his sense of wonder, and curiosity realizes that something in “empty” space controlled the needle; he later on describes the experience as a revelation of his life. Albert Einsteins hobbies was to build models and mechanical devices for his amusement although he showed...

...BRAIN DRAIN Human capital flight, more commonly referred to as "brain drain", is the large-scale emigration of individuals with technical skills or knowledge. The reasons usually include two aspects which respectively come from countries and individuals. In terms of countries, the reasons may be social environment (in source countries: lack of opportunities, political instability, economic depression, health risks; in host countries: rich opportunities, political stability and freedom, developed economy, better living conditions). In terms of individual reasons, there are family influences (overseas relatives, and personal preference: preference for exploring, ambition for an improved career, etc. Although the term originally referred to technology workers leaving a nation, the meaning has broadened into: "the departure of educated or professional people from one country, economic sector, or field for another, usually for better pay or living conditions". Brain drain is usually regarded as an economic cost, since emigrants usually take with them the fraction of value of their training sponsored by the government or other organizations. It is a parallel of capital flight, which refers to the same movement of financial capital. Brain drain is often associated with de-skilling of emigrants in their country of destination, while their country of emigration experiences the draining of skilled individuals. The term brain drain was coined by the Royal Society to describe the emigration...

...BUS-5013: Robert Servais ID: 0323483 Overview, Historical Context and Development of Technology Since the dawn of the Information Age in the 20th century, academics, governments, big business and tech savvy consumers have all been granted access to endless amounts of data through an online repository with the simplicity of a mouse click. The amount of information available to the world is a triumph mainly attributable to breakthroughs such as those given by Tim Berners-Lee with his introduction of the World Wide Web in the early 1990’s, and constant developments in computer science and computational power made possible through advances in microprocessing capabilities which seem to be paralleling closely with forecasts given by Moore’s Law (Greenemeir, 2009). Moore’s Law, which is not exactly a law, is an estimation regarding the progression deemed possible in an integrated circuit. It was postulated by one of the founders of Intel, Dr. Gordon Moore, who stated that the number of transistors placed on a circuit will double roughly every 18 months (Colwell, 2013), and the capacity to follow this trend will end at a critical point when transistors become so close together that the manifestations of quantum mechanics will begin to transpire (Tally, 2012). Classical computers have undoubtedly reshaped our world and have provided incalculable progress unforeseen through the eyes of some of history’s greatest academics. Early computers were mammoth-sized mechanical devices utilized...

...Truth and Reality: Are our versions mere mind-created, or real ? Can we ever distinguish actual reality from the synthetic models that mind create ? Or, can we ever know any reality other than what our minds create ? If we clinically analyse the total contents of our mind, we will find that it is a mix of many things that we consider as real, and equal number of things that we know as mere manufactured products of we,or that of the human community in general. What we naively consider as real are objects and relations that we have seen, heard, touched,tasted or smelt. We had learned this criterion of assessing reality from our primeval days when mind was not developed to perceive anything beyond what were just in-front the sense-organs. Animals are still in worlds of reality. Now, man's this category of reality also consists the various scientific facts,that we believe, our prestigious men of science must have either directly observed through their special instruments, or inferred over strong evidences they must have collected through their various false-proof methods. For example, the moon-rocks are real because NASA has its samples displayed at their facilities, or it is Sun there at the center of solar system, and earth and other planets are revolving around it. We believe that Science has adequate proof of these real physical facts. Though these scientific facts are quite different from the reality of a horse or a mountain that we actually see, we generally...

...Hawking contra Philosophy Christopher Norris presents a case for the defence. Stephen Hawking recently fluttered the academic dovecotes by writing in his new book The Grand Design – and repeating to an eager company of interviewers and journalists – that philosophy as practised nowadays is a waste of time and philosophers a waste of space. More precisely, he wrote that philosophy is ‘dead’ since it hasn’t kept up with the latest developments in science, especially theoretical physics. In earlier times – Hawking conceded – philosophers not only tried to keep up but sometimes made significant scientific contributions of their own. However they were now, in so far as they had any influence at all, just an obstacle to progress through their endless going-on about the same old issues of truth, knowledge, the problem of induction, and so forth. Had philosophers just paid a bit more attention to the scientific literature they would have gathered that these were no longer live issues for anyone remotely au fait with the latest thinking. Then their options would be either to shut up shop and cease the charade called ‘philosophy of science’ or else to carry on and invite further ridicule for their head-in-the-sand attitude. Predictably enough the journalists went off to find themselves media-friendly philosophers – not hard to do nowadays – who would argue the contrary case in a suitably vigorous way. On the whole the responses, or those that I came across, seemed overly anxious to strike...
