Abstract This essay explains the basis of Quantum Mechanic Theory of the atom, which describes the behavior of electrons in atoms & molecules. The author examines this theory and provides a detailed analysis of it.
From the Paper "The Quantum Mechanics Theory describes the behavior of electrons in atoms & molecules. Quantum Mechanics is also referred to as Wave Mechanics. The theory of quantum mechanics tells us that in the atom, electron waves are standing waves. This theory was devised by Max Planck in 1901. He stated that light is emitted by the atoms of a luminous body in separate packets or bundles of energy called quanta or photons. One or more of the electrons revolving about the nucleus of an atom can be made to jump from one orbit to another. As they do so one or more photons are emitted. This energy radiates from the luminous body as electromagnetic waves. The energy content of a photon determines the length and frequency of the wave. Wave mechanics views the probability of finding an electron at a given point in space."

Abstract This paper discusses the development of quantum mechanics, illustrating its background which began with the classical theory of the atom, continued to Bohr?s simple atomic theory, and was developed further with de Broglie?s wave theory, Heisenberg?s uncertainty principle and Schrodinger?s equation. To further investigate the development of quantum mechanics, each of these stages are looked at in more detail, showing the main ideas that each stage added to the understanding of the atom. This paper shows that quantum mechanics is based on the combination of the ideas of many scientists, with the final acceptance of quantum theory occurring when Schrodinger?s equation tied together previous theories and allowed them to be applied to subatomic particles.
From the Paper "The classical theory of the atom is based on the model of an atom being made up of a positive nucleus containing protons and neutrons with negatively charged electrons orbiting around this nucleus. This model was first proposed by Rutherford in 1911 who described the atom saying, ?Most of the volume of the atom is empty space in which electrons move around the nucleus.? This basic model of the atom has been expanded on and used to determine how chemicals react with each other, the charges of chemicals and the physical properties of chemicals. While this has involved expanding the theory, the basic understanding of the structure remains the same."

Conclusions
From the Paper "The fact that statistical physics can be taken as a particular type of statistical inference does not seem to play too much of a theoretical role in physics today. It is perhaps the strong suggestion of subjectivity associated with the concept of inference that determines physicists to rely mostly upon kinetic basis of statistical laws. However, recognized or not, the statistical inference has played a very important part in such fundamental problems like building physical concepts. One illustrative example is the concept of quantum. Originally related to the frequency property of light, it was in time explained as associated with its particle properties, then with the temperature of light. All these properties can be traced logically back to the particular type of statistics which is fundamental for the ensembles characterizing the black body radiation. More than this, that very type of statistics is essential in the contemporary sophisticated descriptions of the squeezed states and their related concepts. This essay presents details of the statistics involved in the history of quantum, and the essential points of this history."

The ?Theory of Everything? and Stock Markets, 2003. The application of science's "Theory of Everything" to understanding stock markets. 2,066 words (approx. 8.3 pages), 6 sources, MLA, $ 65.95 »
Click here to show/hide summary
Abstract This paper expounds the ?Theory of Everything,? starting with the pioneering theories of Newton?s ?Laws of Motion? and Einstein?s ?General Theory of Relativity,? developing right through to the cutting-edge ?string theory? research currently being conducted around the world today. It shows the importance of fields of study as seemingly diverse as calculus, differential geometry, electromagnetism, particle physics and quantum mechanics to the development of a ?Theory of Everything?. It also demonstrates how those with access to this theory can use the knowledge as power for anything, such as understanding stock markets using the premise that the stock market moving up over time means that these are not random movements and therefore should be explainable.
From the Paper "Stock markets exist over time and space (the geographical markets) that we are able to quantify and understand to a degree. Therefore, as with Einstein, we are fairly comfortable with the stock market in its familiar four dimensions. We have become accustomed to inflation; the rising of prices of goods rise over time and this is obviously a major reason for at least part of the upward rise of share prices. However, what happens when we explore the smaller dimensions ? like the six unknown dimensions string theorists grapple with? Like the string theorists who know that subatomic matter exists but can?t explain or predict its behavior, we often know what influences the stock market but are usually unable to predict it."

Abstract This paper expounds the ?Theory of Everything,? starting with the pioneering theories of Newton?s ?Laws of Motion? and Einstein?s ?General Theory of Relativity,? developing right through to the cutting-edge ?string theory? research currently being conducted around the world today. It shows the importance of fields of study as seemingly diverse as calculus, differential geometry, electromagnetism, particle physics and quantum mechanics to the development of a ?Theory of Everything?.
From the Paper "However, there is a fundamental discord between Einstein?s ?Theory of General Relativity? and quantum mechanics. Einstein saw the universe in four dimensions (the three dimensions of space plus time). The gravitational force that binds matter to the earth stems from this space-time continuum. Since quantum mechanic?s subatomic particles only exist theoretically, they cannot be located in space-time and their motion can only be hypothesized. Thus, we have two theories that work individually but not together. There are also many unanswered questions. Relativity cannot tell us how the big bang created the universe or what black holes consist of. Similarly, quantum theory is not able to make order or sense of the assortment of miniscule matter it describes."

String Theory, 2005. A look at a theory within the realm of physics known as string theory. 1,500 words (approx. 6.0 pages), 5 sources, MLA, $ 49.95 »
Click here to show/hide summary
Abstract This paper explains string theory, which has been put forth by physicists in an effort to develop a theory of gravity that can be incorporated into the quantum understanding of nature. The paper explains that string theory hypothesizes that classical point particles are actually infinitesimally small lines or, perhaps, loops and that the theory supports the concept that all quantum particles, including the messenger particle of gravity, or graviton, are components of a single, master superfield.
From the Paper "Generally speaking, considering the enormous amount of matter that was concentrated in a tiny space after the Big Bang, the setting for unification is contained by almost unbelievable energy levels. Efforts to achieve this "mathematically" have been reasonably successful and are termed Grand Unified Theories, or GUT. So far, physicists have managed to unify the electromagnetic, weak, and strong interactions into one formalism."

Superstring Theory, 2005. An analysis of the theories that led to the superstring theory on the nature of the universe. 900 words (approx. 3.6 pages), 2 sources, $ 35.95 »

Abstract This paper discusses the various theories that were developed beginning at the end of the nineteenth century and leading over time to superstring theory as a way of explaining the fundamental nature of the universe, with necessary earlier ideas including relativity theory, quantum theory, and the idea of higher dimensions over the four usually cited.
From the Paper "The development of superstring theory required a number of theoretical shifts from the earlier Newtonian model of the universe, which itself had supplanted other ideas about the nature of reality. In this development, the nature of the human relationship to the universe changed because of scientific theories of the time that were offered, that countered the prevailing beliefs, and that seeped down into the culture to be expressed in art, literature, and the popular press in various ways. The central figure in this shift was Albert Einstein, though he was not alone in making discoveries that would alter the prevailing Newtonian, Copernican, and common-sense view of time and space and the immutability of both."

It examines the changing airline industry and evolving occupation of aircraft mechanics. Includes details of what the profession entails and what skills are appropriate as well as the positive future outlook for those who choose to work in the field.
From the Paper "The airline industry is an ever-changing field. There are many types of aircraft being used today, including, freight, commercial passenger and private passenger planes. Each plane has to be built, maintained and fixed when something goes wrong. The field of airplane mechanics is a growing and always changing area of job exploration. Skills as an aircraft mechanic can be utilized in the armed services, the commercial airline field, or at an airfield with private aircraft. They can also be used to work where airplanes are sold and brought in for maintenance and repair. It is a field that promises to continue expanding and as the world continues to globalize the opportunities will continue to increase."

Abstract This paper discusses, summarizes and reviews Dudley Johnson's article "William Harris Garland: Mechanic of the Old South", describing the life led by the main character, William Harris Garland, the economic situation of the era and the character of Garland. The paper also discusses the importance that Johnson places on the role Garland played in American history along with the thousands of other like Garland.
From the Paper "Today, too many of us still think of "The Old South" at the beginning and middle of the Nineteenth Century as either made up of wealthy plantation owners, or slaves. Garland's experiences which he wrote down in a lot of letters were those of an itinerant mechanic, moving from place to place, trying to find work, and often trying to travel without a cent in his pocket. William Garland, as described in Johnson's article. Was one of "a number of skilled workmen in the South prior to the Civil War, and the work they did was vital to the region (Johnson 41). Like so many itinerant workmen today, "he and his friends had no interest in the political situation. They were more concerned with obtaining and keeping jobs and with reducing their financial insecurity" (41)."

Quantum Tunneling, 2007. An analysis of the theory and uses of quantum tunneling, specifically the Esaki diode. 2,194 words (approx. 8.8 pages), 6 sources, MLA, $ 68.95 »
Click here to show/hide summary
Abstract This paper discusses quantum tunneling, which is a function of quantum-mechanical activity in the instance where a particle moves against potential energy and appears on the other side of the energy barrier. The paper describes the theory behind quantum tunneling. It focuses on the Esaki diode and looks at its potential uses now and in the future.
From the Paper "While the Esaki diode has not been widely used, its application is nearing widespread use in computers. The diode circuits have been developed and crash programs have been implemented by major computer makers in order to apply it to communications equipment. Yet there still is resistance to the use of these phenomenal little circuits, where currents may be reversed. Some designers and engineers prefer transistors. Proven circuits and solid-state technology that is already acceptable seem to be sufficient, they say. But interest in the diode is so great that they are being forced to try to apply this not-so-new technology to obtain ultra-high speed and ultra-low power consumption in the computer industry. The diode phenomenon dominated 1960 Physics Conferences."

Physical Theories to Account for Psi Phenomena, 2002. An examination and discussion of different theories proposed to explain clairvoyance, precognition, psychokinesis and other psi phenomena including electromagnetic radiation and quantum theory. 1,055 words (approx. 4.2 pages), 4 sources, MLA, $ 37.95 »
Click here to show/hide summary
Abstract The strengths and weakness of various theories including extremely low frequency (ELF) electromagnetic radiation waves and quantum theory as it applies to psi are discussed. Also examined are the problems of scientific paradigm shifts and the possibility that the statistical evidence for psi activity is an "anomaly" in our current paradigm and a precursor to a paradigm shift.
From the Paper "Parapsychology occupies a unique position within the scientific realm. The results of the field are often considered invalid, fraudulent, or insignificant. Psi is often thought to be inconsistent with the current knowledge of physics. Despite the large body of statistical evidence for anomalous cognition, psi will not be widely accepted until a solid, testable physical theory is developed. Although the uncertainties and seemingly illogical consequences of quantum theory seem promising for the development of this sort of theory, as yet none exists."

The Atom, 2004. A brief overview of the make-up of the atom and the history the atomic theory. 700 words (approx. 2.8 pages), 1 source, MLA, $ 24.95 »
Click here to show/hide summary
Abstract The atom is the very smallest unit of matter or the smallest part of a chemical element that still contains all the parts of that element. Atoms are the very heart of our chemical elements, and harnessing the atom has been a long, historic process. This paper shows that atoms have been known about for a while in history, but it was not until the 20th century that scientists learned how to harness the power of the atom and use it effectively.
From the Paper "Today, scientists have uncovered much more information about the elements that make up the atom, including baryons, quarks, and antiparticles. Because we understand more about the composition of the atom, we can use it more effectively. For example, scientists often use protons in particle accelerators, (sometimes called "atom smashers"), which create beams of actively charged particles and then point them toward targets. The energy created by these accelerators help scientists study the nucleus of the atom, and create the nuclear energy that will create new particles."

The Theory of Atomism, 2008. This paper examines Bertrand Russell's theory of atomism. 2,782 words (approx. 11.1 pages), 8 sources, APA, $ 83.95 »
Click here to show/hide summary
Abstract The paper explains Bertrand Russel's theory of atomism, which emphasizes logical analysis and its consequences for metaphysics. The paper describes how Russel explains the structure of the external world and discusses how pluralism, rather than monism, is the logical force behind the philosophy. The paper also looks at the many arguments against Russell's theory of logical atomism.
Outline:
Introduction
The Structure of the World
Russell's Logical Atomism
Logical Atomism - Realistically Logical?
Conclusion
From the Paper "Bertrand Russell, author of the theory of atomism, was a philosopher whose emphasis was primarily on logical analysis and its consequences for metaphysics. The traditional philosophical problem of the external world, which is based on the fact that external qualities can only be drawn inferentially, was explained by Russell (1910) as a distinction between "knowledge by acquaintance and knowledge by description" (Irvine, 2003). Russell's 1918 work on logical atomism was based on the argument that the world is comprised of logical atoms, which he described as "little patches of colour", and their properties (ibid). Together these properties, according to Russell, form the atomic facts which are thus combined to create logically complex objects. Therefore what is normally explained as inferred entities, such as enduring physical objects, are actually logical constructions created from immediate entities of sensation, which Russell identified as "sensibilia" (ibid)."

The Origins of The Mechanical Clock, 2006. A discussion and exploration of the origins of the mechanical clock. 1,350 words (approx. 5.4 pages), 4 sources, $ 53.95 »
Click here to show/hide summary
Abstract The mechanical clock is one of the most common technologies in the Western world. The fact that the mechanical clock is so common means that many people have a difficult time believing that there have been periods of time in which the mechanical clock did not exist. In this bibliographic essay the origins of the mechanical clock are examined. The paper demonstrates that the mechanical clock did not simply spring into existence as a result of a single innovation. Instead the mechanical clock resulted from a number of technological and social developments.

The Atomic Bomb, 2008. This paper discusses the atomic bomb and provides an analysis of its
moral implications. 1,359 words (approx. 5.4 pages), 4 sources, MLA, $ 45.95 »
Click here to show/hide summary
Abstract This paper relates that the atomic bomb has dramatically changed the world we live in and will continue to strike fear into the every day lives of civilians. The paper asserts that the making of the atomic bomb was inevitable, but the use of the atomic bomb was a mistake that will never be forgotten. The paper goes on to say that the atomic bombings of the Japanese cities of Hiroshima and Nagasaki in August 1945 ended the bloodiest war in human history, but Japan was on the verge of surrendering anyway, so there was no military justification for the use of these horrific weapons. The writer concludes that if humanity fails to break free from the vicious cycle of wars, atomic bombs will be used again, life on earth will end someday in one final conflagration and the final page of human history will never be written because no one will be left alive to write it.
From the Paper "Despite the fact that most Americans in 1945 considered these atomic attacks fully justified and felt no remorse for the massive death and destruction inflicted upon Hiroshima and Nagasaki, most Americans today have very different attitudes about the atomic bombings, and feel regret, shame, and revulsion when they think about the atomic attacks. Most of them believe that although the making of the atomic bomb was inevitable, it was a mistake to use atomic bombs against Japan."
"The Manhattan Project was established early in World War II because it was learned that Nazi Germany was intent upon building an atomic bomb. This political factor, combined with the relentless advance of scientific discoveries, made the development of atomic weapons inevitable. Consequently, a race to develop atomic bombs began, for they would be the ultimate weapon and whichever nation possessed them would be impossible to defeat."
