...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...

...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...

...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...

...working inputs for climatological models or the theories they are derived from. Research and examination of radiation laws raises doubts about the viability of such averaged inputs, and this reasoning is used to inform and test a hypothesis. Background The purpose of this paper is not to go into a full derivation of the physics behind the absorption and emission of electromagnetic radiation. Planck, Stefan, Boltzmann, Einstein, and Wien were all better suited to such an examination, and the experimental apparatus needed to plumb the realms of quantum physics further is not easily acquired. The work of Stefan and Boltzmann is accepted herein as a valid description of the ideal case where emissivity is equal to unity, also known as a black body. The discovery in 1905 by Einstein[1] that emission spectra are quantized is not his most famous finding, of course, however it is the one for which he received a Nobel Prize. While his work with other scientists in Brussels is not as well known, one of his fellow Nobel Laureates Max Planck initially rejected, but was later convinced by Einstein who had expanded on Planck's earlier work on what is now known as the Planck Law of black-body radiation. Planck[2] himself was seeking a resolution to the problems plaguing the earlier work of Wien, which correctly predicted radiative properties at high frequencies, but did not work at shorter ones. Later Planck would say that it was in an “act of despair” that he revised his work using...

...professionals. Born in Germany, He was the eldest of two children born to Hermann and Pauline Einstein. Mostly known for his “Theory of Relativity”, which challenged all ideas of space and time once set by Sir Isaac Newton, Albert took an early interest in science. At age five, when he was intrigued by a compass’s invisible forces, and again at age twelve, when he found a book on geometry. At sixteen, he wrote his first scientific paper titled: “The Investigation of the State of Aether in Magnetic Fields.". In which he questioned “If the light were a wave, then the light beam should appear stationary, like a frozen wave. In reality, the light beam is moving.” This paradox would dominate his thinking for the next ten years. In 1905, while working in a patent office, Einstein submitted a paper for his doctorate and had four other papers published. It was four articles that would present grant Einstein his academic recognition, and where the famous “E=mc2” equation first appeared. The physics community initially dispelled Einstein until the founder of quantum theory Max Planck, garnered his attention. Einstein’s success continued to rise equally as fast as the Nazi regime began to take power in Germany. In 1920, Hitler and the Nazi regime began to denounce Einstein’s theories as “Jewish Physics”. They gained control of the German government and prevented any Jew from holding any official position, including teaching in Universities. Despite the negative attention, in 1921 Einstein won the Nobel...

It’s no secret that the Philippines is addicted to video games, in fact if you’re in a city in the Philippines, you can find an internet cafe within walking distance, and if you enter that internet cafe, there are bound to be teenagers there playing DotA or Counter-Strike or some other game. This isn’t a bad thing because it develops friendship, teamwork and the ability to socialize. According to Jason B. Almonte (June 22, 2011) in his case study entitled “Implementation of a digital game-based learning environment for elementary Education” he stated that, “Video games have gained high popularity nowadays that researchers have taken an interest in its use as an educational medium. Based on previous studies on educational game development, the project has developed video games for mobile handheld devices that cover Grade 6 Philippine Educational System Science curriculum topics.

...Entrepreneurship TERM PAPER Research paper on the subject of whether it’s better, as a career choice, to be an entrepreneur or work for others Is it better to be an entrepreneur or an employee? Most of the academic research focuses on finding external factors or personal qualities that create entrepreneurs. In early academic papers emphasis has been on psychology and sociology, while more recent research is focusing more on economic perspective. Overall, entrepreneurs are a minority if compared to paid employees. There are most certainly more people who choose to work for someone else rather than attempt to be an entrepreneur. Reasons behind this career choice are very different. Most obvious reason for a rational person might be financial benefits. Research done by Hamilton (2000) shows that initial earnings as well as earning growth is much larger for paid employees in the first 10 years if compared to entrepreneurs, not even including fringe benefits. However, money is definitely not the only factor that affects the career choice when it comes to a decision, whether to become an entrepreneur or to go work for someone else. If entrepreneurs are perceived as utility-maximizing individuals, then independence, risk bearing, work effort, and perquisites associated with self-employment plays a very vital role in their career choice (Douglas and Shepher, 2000). In the following parts of this research paper, various benefits and shortcoming of being an entrepreneur...

...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...

...Research Paper No. 2008/20 Entrepreneurship in Economic Development Wim Naudé * March 2008 Abstract What is the role of entrepreneurship in economic development? At a minimum the answer should be able to explain the role of entrepreneurs in the structural transformation of countries from low income, primary-sector based societies into high-income service and technology based societies. More broadly though, it should also be able to explain the role of entrepreneurs in the opposite pole of stagnating development (including conflict) and in high innovation-driven growth. Although economic development lacks a ‘general theory’ of entrepreneurship, which could encompass a variety of development experiences, much progress has been made in extending the understanding of entrepreneurship in the process of development. This paper surveys the progress with the purpose of distilling the outlines for a more general theory of entrepreneurship in economic development. Entrepreneurship in developing countries remains a relatively under-researched phenomenon, so by surveying the current state of research, and by discussing the role of entrepreneurship in dual economy models of structural transformation and growth, a secondary objective of this paper is to identify avenues for further research. Finally, the policy implications from the economic literature suggest that a case for government support exists, and that this should focus on the quantity, the quality, and the allocation of entrepreneurial...

This problem occurred in the restaurant where workers got conflicts during working hours. One of my peers, Lohnet Barton has introduced the final solution for the manager. From my own perspective, I will carefully explain the incident and analyses the way that Lohnet resolved the conflicts. Also; I will carefully do examination in the process that she took in order to decide which course of action that needs to follow. Besides, there will be an appropriate decision making strategy that was used as an effective tools in Lohnet decision making journey. To make it easier, I will begin by shortly giving the readers the whole picture of the situation that took place.

...Published in: Swiss Journal of Economics and Statistics, 133 (2/2), 1997, 201–218. © 1997 Peter Lang, 0303-9692. Bounded Rationality: Models of Fast and Frugal Inference Gerd Gigerenzer1 Max Planck Institute for Psychological Research, Munich, Germany Humans and other animals need to make inferences about their environment under constraints of limited time, knowledge, and computational capacities. However, most theories of inductive inferences model the human mind as a supercomputer like a Laplacean demon, equipped with unlimited time, knowledge, and computational capacities. In this article I review models of fast and frugal inference, that is, satisficing strategies whose task is to infer unknown states of the world (without relying on computationaly expensive procedures such as multiple regression). Fast and frugal inference is a form of bounded rationality (Simon, 1982). I begin by explaining what bounded rationality in human inference is not. 1. Bounded Rationality is Not Irrationality In his chapter in John Kagel and Alvin Roth’s Handbook of Experimental Economics (1995), Colin Camerer explains that “most research on individual decision making has taken normative theories of judgment and choice (typically probability rules and utility theories) as null hypotheses about behavior,” and has labeled systematic deviations from these norms “cognitive illusions” (p. 588). Camerer continues, “The most fruitful, popular alternative theories spring from the idea that limits...
