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."

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."

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."

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 »
Click here to show/hide summary
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."

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."

Bell?s Inequality, 2002. An insight into Bell?s Theorem (Bell?s Inequality) of quantum theory. 2,115 words (approx. 8.5 pages), 3 sources, MLA, $ 66.95 »
Click here to show/hide summary
Abstract This paper discusses the work of the physicist John Bell, who's great recognized achievement occurred during the 1960s when he brought new life into the foundations of quantum theory. It examines how Bell demonstrated that discussion of such concepts as 'realism', 'determinism' and 'locality' could be formed into a rigorous mathematical statement, 'Bell's Theorem?, which is capable of experimental test. It looks at how his work has become a point of interest for scientists throughout the world who have found applications not only in quantum theory, but in investigations of the physical universe as well and how current applications of Bell?s Inequality have been found in the development of quantum computing and quantum cryptography.
From the Paper "Quantum mechanics, however, fails to satisfy Bell's Inequality. He predicts correlations that cross over boundaries that are delineated by the structure of that inequality. Quantum mechanics predicts ?odd? correlations that seem to defy a common, classical conception of reality, and in fact it is for basically this type of reason that Einstein, Podolsky, and Rosen argued in 1935 that it was incomplete. The formulation of Bell's Inequality, however, allowed the possibility for determining, through experiment, which was right: quantum mechanics or a local reality theory of the sort Einstein postulated, because it stated what must be the case in our experiments if a locally real theory is correct."

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."

The Question of Reality, 2007. A discussion on reality as perceived in quantum theory, specifically holographic theory. 1,142 words (approx. 4.6 pages), 3 sources, MLA, $ 39.95 »
Click here to show/hide summary
Abstract The paper examines how beliefs on the nature of reality have a direct impact on what one brings into her experience. The paper explores how what we "see" all around us is an interpretation of what really exists. The writer argues that, from a Christian standpoint, God is perfect. People have to learn to see perfection. The essay discusses quantum theory (specifically holographic theory) and argues the probability that human beings literally create an objective sense of reality.

From the Paper "Eventually, he found that the physical senses perform a frequency analysis to construct a sense of solid reality. The "solid" image is a hologram. The brain receives input, which it fits together to form a perception of the world. This discovery led Pribram to question the nature of reality. He asked, which is reality--the objective world we seem to experience--or interference patterns perceived by a holographic brain that converts frequency patterns into three-dimensional images? He concluded that we live in a frequency domain. It doesn't become the "world" until after our senses perform an analysis and construct an image!"

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."

Quantum Mechanics, 2002. An analysis of the development of quantum mechanics, including an outline of the stages which led to the development. 1,847 words (approx. 7.4 pages), 7 sources, APA, $ 59.95 »

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."

Quantum Cryptography, 2007. An overview of the use of and the theory behind quantum cryptography. 1,906 words (approx. 7.6 pages), 8 sources, MLA, $ 60.95 »
Click here to show/hide summary
Abstract This paper examines how quantum cryptography is a fast growing form of encryption that is not based upon the difficulty of mathematical algorithms and instead employs quantum physics to encrypt information on the physical level. It emphasizes the need for an innovative cipher as well as the need to inform the IT community regarding the commercial application of quantum cryptography. It also provides a broad overview of the quantum cryptographic protocol and operation using fiber optic media.
From the Paper "The integrity of information between sender and receiver relies upon secure channels and more importantly the ability to protect the information from unauthorized recipients. The transmission of information can be compromised when a third party listens in on the transmission media measuring the physical object. Consequently, the eavesdropper can effectively intercept the contents of a communication. Certain types of classical cryptography have proven vulnerable to the interception of data and the incident can remain undetected during the entire transmission. This idea of a man-in-the-middle attack on communication media using quantum cryptography is not possible due to the laws of quantum mechanics. Quantum superposition's and quantum entanglement are two properties of quantum physics used to detect eavesdropping. "

Quantum and Biological Computing, 2001. A comparative look at two new technologies in computing - quantum and biological. 1,800 words (approx. 7.2 pages), 5 sources, MLA, $ 57.95 »
Click here to show/hide summary
Abstract This paper looks at the differences between two new technologies, quantum and biological computing, examining how they can be used in different fields. It examines problems experienced in the development of these computing techniques but also shows how much of an impact they would have on current technology. The writer explains that instead of using microchips, a quantum computer uses a liquid of appropriate molecule which is more accurate.
From the Paper "Quantum and Biological computing are two technologies which are on the forefront of advancement in computers today. Both technologies are relatively in their infancy, but so far there have been a good amount of promising results in both research and prototypical experimentation. The reason behind the quest for a different type of computing system is not simply for the purpose of advancement for the sake of advancement; but rather because conventional microchips are nearing the apex of their computation ability for certain applications. There is a lot of competition in the field of quantum computing, both for the financial gain, and scientific breakthroughs which would result in a practical quantum computer. The field of Biological computing is one which does not hold the promise of quantum computing, as far as practical application; But does open new doors into the realm of computing without being tied to digital circuits and all the limitations they possess. Conventional computers can be improved by further miniaturization of circuits, but the major roadblock is that transistors and electrical wiring can ultimately only be made as slim as the width of one atom. Once again business and science are teaming up in order to benefit each other, and bring about the next great evolution in computing technology."

From the Paper "Quantum Corporation was founded in 1980 in California and since then has managed to capture a significant portion of the digital and analog storage media market. At the start of the year 2000, for example, the company already employed 6,300 employees and showed no indication that growth wasn't an inevitable part of the company's future. Quantum operated with extreme authority in the market, providing storage media for all the major PC manufacturers, not to mention storage solutions to others such as the makers of TiVo. To give some perspective, in the year 2000, Quantum managed to ship 30 million desktop drives, retained its title as the market share leader for the seventh year in a row, and captured 24% of the total market (McAfee 2)."

Test-Tube Quantum Computer, 2002. An examination of the technology of test-tube computers and its expected future uses. 2,125 words (approx. 8.5 pages), 6 sources, MLA, $ 66.95 »
Click here to show/hide summary
Abstract This paper explains how scientists have developed a computer that processes information running on DNA. It discusses how the computer is so microscopic it can?t be seen by the human eye. The implications for the future are tremendous, and it is now feasible to believe that sometime in the future, man will become part human and part computer. It discusses how the technology that scientists are currently developing may allow tiny computers to analyze, assess and correct biochemical abnormalities before they manifest themselves as problems.
From the Paper "Test Tube computers came about as the idea that a computer can be so small that ?a trillion of it?s kind can fit into a test tube.? The idea was developed by researchers at the Weizmann Institute in Israel, who developed a nano-computer that consists of DNA and DNA-processing enzymes which are dissolved in a liquid (Noble, 2001). DNA has always functioned as somewhat of a mini computer, and strands of DNA are so small they can?t be detected by the human eye. The discovery has lead researchers to believe that it is possible to perhaps develop a device that is ?capable of processing DNA inside of the human body, finding abnormalities and creating healing drugs? (Noble, 2001). A momentous occasional in revolutionary history."
