Abstract
This paper introduces, discusses and analyzes the topic of Albert Einstein. Specifically the paper discusses Einstein's life and his scientific achievements. The paper reports that Einstein discovered the 'Theory of Relativity' and is often known as the "father" of the atomic bomb. The paper further discusses how Einstein's life is a model to scientists and physicists today, and a valuable lesson in what one person can accomplish in his lifetime.
From the Paper
"Einstein also helped to develop Quantum Theory, which "deals with the laws that describe how matter is built out of these elementary particles and what the forces are between them as revealed in spectral lines, in radioactive phenomena, or in the process of fission. The story of modern physics is in great part that of quantum theory" (Infeld 85). The use of Quantum Theory and continued study into it by other scientists eventually led to the development of atomic fission, and later, the development of the atomic and bomb. Einstein always regretted the part he played in the development of the bomb, as he was a lifelong pacifist. In fact, he co-wrote a famous book, "Why War?" with Sigmund Freud in 1932 that became classic anti-war literature. Another writer states, "The 'Why War?' letters, organized by Einstein, were written at the behest of the International Institute of Intellectual Co-operation, a committee of the League of Nations" (Dunn 112). Einstein saw the potential of harnessing atomic principles to create nuclear power, but always felt regret over his role in the atomic arms race. He spent the remainder of his life studying many different projects. One however, eluded him. Another scientist writes, "Einstein, who had already united space, time and gravity in his theories, certainly believed this and spent the latter half of his life seeking--unsuccessfully--'a theory of everything' that would combine quantum physics and relativity" (Mckie). That work today is evolving into another theory of physics - string theory, which shows his influence is still felt around the world today."

Abstract
This paper examines how a star is a huge, shining ball in space that produces a tremendous amount of light and other forms of energy. It looks at their physical makeup, the different types, and the recycling effect of star evolution on the rest of the universe.
From the Paper
"Stars have many variants such as age, size, mass, and luminosity, but one thing they have in common is that "about 75 percent of all stars are members of a binary system, a pair of closely spaced stars that orbit each other" (Green, 2005, p. 1). Stars are also grouped together in galaxies such as the Milky Way which hosts more than 100 billion stars. "Three-dimensional computer models of star formation predict that the spinning clouds of dust may break up into two or three blobs; if true, this would explain why the majority of the stars in the Milky Way are paired or in groups of multiple stars" (science@nasa, p.1). Clearly, the structure and formation of individual stars mimics the structure of other important elements of the universe."

Why He Succeeded
From the Paper
"Edison's childhood was one of constant, almost relentless curiosity. It was a trait that would serve him well when he eventually went on to hold a world record for having more than 1,000 patents, but while he was still a child it sometimes caused him a great deal of stress. One example of this was the time he accidentally burnt down a family barn in his quest of experimentation. He was charged with the crime of arson at the tender age of six for that mishap but it didn't slow him down. There were also questions about his intellectual abilities at one point. Stories are told that a friend of his drowned while Edison was playing with him at a creek and Edison failed to show any emotion. In addition he had a teacher tell his parents that he was "dumb" and would never be able to learn(American Heroes: Thomas Alva Edisonhttp://www.mccsc.edu/~jcmslib/mlk/edison/biography.htm) . "

Abstract
A discussion regarding the world's current dependence upon fossil fuels as the primary source of energy. The paper discusses other alternative types of energy such as wind power, solar power, nuclear power and natural gas.
From the Paper
"Safe, efficient, reliable, and less environmentally damaging than traditional energy resources, natural gas is generally perceived as the most likely choice for the near future. Natural gas utilizes both a steam and gas cycle to generate power, and therefore, releases far fewer greenhouse gases into the atmosphere than coal or oil. But, "Even though air pollution concerns are much lower with gas fired plants, there are other environmental concerns including water use and water pollution. Combined cycle plants use about 10 million gallons of water per day, consuming 7 million and putting 3 million gallons back into nearby rivers," (Power Frontiers). Nevertheless, natural gas does contribute to global warming--less so than other methods but more so than nuclear energy. Both are comparably cheap and sustainable, but natural gas is considered to be safer to the public. All things considered, natural gas is economically viable, relatively safe, relatively clean, and sustainable: it poses the most realistic option for electric companies with its most serious competition coming from coal, and perhaps, nuclear power."

Abstract
This paper discusses John von Neumann's contributions to the fields of quantum physics, functional analysis, set theory, economics, computer science, numerical analysis, hydrodynamics, statistics and other mathematical fields. The paper also discusses his contribution to the creation of the hydrogen bomb. It goes on to describe some of his most influential achievements.
From the Paper
"John Von Neumann inarguably contributed a wealth of knowledge to the development of computers, and without his contributions the face of technology today would be primitively underdeveloped. However, Neumann may have canceled out the "good" he did in an act of self-fulfilling equivalent exchange with his work in the realms of math and science with the contributions he made to warfare and massive weaponry. The name Von Neumann is associated as much with the Atomic Bomb as it is with computer programs (Wilson), and Neumann may have had even more devastating projects on the horizon at the time of his unexpected death from cancer. During the Second World War, von Neumann worked as a consulted to both armed forces and civilian agencies that were involved in wartime projects. Neumann's genius was in high demand, and he was able to design an implosion method for bringing nuclear fuel to explosion, as well as playing an integral part in the development of the hydrogen bomb. (Cabrera) According to one of Neumann's biographers, "It has been stated that von Neumann's electronic computer hastened the hydrogen bomb explosion on November 1, 1952." (Bochner)"

Abstract
This paper discusses the energy trade in the United States. It discusses the increasing need for energy compared to the consumers' decreasing knowledge about where energy is coming from. The paper then discusses President Bush's State of the Union Address for 2006, in which he outlined his new advanced energy initiative, with the overall goal of reducing dependence upon Middle Eastern oil. It then addresses this goal to further advance the use and technology of solar and wind energy resources.
From the Paper
"Renewable energy has been used in various, yet mostly private applications for many years, with ah classic example of the farmer using a solitary windmill to provide energy to a pump that provides water to his fields or livestock or the application of several solar cells on the roofs of homes, either in remote locations where other sources of power are to expensive to obtain or in the city where the novice environmentalist wishes to "get off the grid." Yet, these applications are very limited and the much larger possible applications and the technology that drives them can be rather expensive, in comparison to other forms of energy attainment, especially with regard to initial investment. One of President Bushes stated goals is to reduce the cost of these investments through the development of less costly technologies. Though is a relatively simplistic look at the actual numbers, wind energy, on its own has increased in capacity significantly in the last few years and the same can be said of solar renewable resources."

Abstract
This paper discusses one of the most significant scientific discoveries of the twentieth century, the discovery of the helical structure of deoxyribonucleic acid (DNA). According to the paper, Watson revealed this discovery in his book, 'The Double Helix: A Personal Account of the Discovery of the Structure of DNA'. This paper reviews Watson's book and the fact that DNA was not discovered by a single person, nor by a group of scientists. The DNA discovery was the result of a complex series of advancements, discoveries and inspirations by many independent groups.
From the Paper
"Watson next goes on a series of European excursions and vacations; including being able to finally listed to Pauling. When he returns to Cambridge in the fall, Watson exhibits less preoccupation with DNA, and hears of the discovery by some bacteriologists that some bacteria actually reproduce sexually. This causes Watson to muse that the microbial genetics of them could be understood within a few years after DNA's structure is discovered. In the meantime, Watson writes that Franklin's X-Ray data "were getting prettier and prettier," (Watson 148). Furthermore, he credits her with obtaining the data indicating that the sugar-phosphate backbone of DNA was actually on the outside of the molecule; still, "She gave no sign . . . of liking helices any better," (Watson 148). Watson continues to explain his faith-based understanding of DNA when he writes, "The idea of the genes' being immortal smelled right," (Watson 153). After this leap of inference, however, Watson learns that Pauling is about to unveil another discovery regarding DNA; this worries most everyone at Cambridge. "

Martin Heidegger, 2007.
An analysis of Martin Heidegger's theories of nothingness.

Abstract
This paper discusses the theories of Martin Heidegger which he presented in a book called "Being and Time." The paper describes his theories of nothingness and human "dread" and compares them to Deepak Chopra's similar quantum physics theories. The paper describes the basic meaning of the theories and concludes that had Heidegger possessed Chopra's gift for simplifying language, his concepts of nothingness might have been recognized sooner.
From the Paper
"Heidegger's theory of human "dread" is interestingly at the core of what he believes to be our deep-seated awareness of "nothing." The fact that humans are deeply aware that we will perish into nothing is what gives defineable value to our human experience. In other words, while we know consciously that everything in our human world will change and die, we also know that this concept does not apply to a world of nothing. Heidegger evidently had no faith in the possibility of an afterlife that might include any thing relative to our human existence. In his view, the inescapable loss of somethingness is at the bottom of the human "angst." (Philosophypages)."

Abstract
This paper offers a detailed history of Einstein and the effects his works have on the world, including nuclear energy. It discusses his many theories and explains that often times these works were of religious motivation. The paper also discusses Einsteins effect not only in the science arena, but also on art and the development of Modernism and Post-Modernism in particular.
From the Paper
"In more theoretical terms, Einstein postulated several theories that challenged the nature of time and suggested both its relative nature depending on how it is measured and the possibility that it is reversible, something that clearly went against the traditional view. Einstein is really the figure around whom the changes in both the sense of time and of space swirl, for his theories challenged both and suggested ways in which both time and space could be changed, bent, twisted, and made into something different than people had once believed."

Conclusions
From the Paper
"President Bush has started giving more importance to alternate energy sources. In order to emphasize the need for alternate energy sources he toured advanced energy technology companies in Wisconsin and Michigan. He talked about different energy sources and new options like nuclear energy, solar power and a hybrid gas-electric car. "Overall, Bush's 2007 energy plan calls for a 22% increase in clean-energy research at the Department of Energy. It seeks to invest more in low-pollution coal-fired power plants, solar and wind technologies and nuclear energy" (Benedetto, 2006)."

Abstract
In this article, the writer studies the character of Josiah Willard Gibbs, a mathematician and physicist. The writer discusses that he managed to achieve great things during his lifetime and lead the world on to greater and better scientific discoveries. The writer points out that Josiah Willard Gibbs has been recognized as one of the greatest American scientists of the nineteenth century. Further the writer notes that it is Gibbs who managed to provide a sound thermodynamic foundation to physical chemistry, to America and to the entire world.
From the Paper
"The second work that Gibbons published in the same year was "A Method of Geometrical Representation of the Thermodynamic Properties of Substances by Means of Surfaces". From the years from 1876 to 1878, Gibbs published two memoirs, which were later to be combined into one work, entitled, "On the Equilibrium of Heterogeneous Substances". Added to this, Josiah Willard Gibbs has contributed to various other spheres, like for example, crystallography, the determination of planetary and comet orbits, and also to electromagnetic theory. The most interesting phenomenon that Gibbs managed to achieve was that he made the practical side of science appealing and fascinating. Gibbs was also recognized as a 'theoretical physicist' of international stature, and he received a patent in the year 1866 for an improved type of railroad brake."

Abstract
This paper discusses the substance, hexane, otherwise known as n-hexane or Hexyl hydride. According to the paper, Hexane is manufactured by the refining process of crude oil and the correct composition of the fraction depends more or less on the source of the oil that is crude or refined and the limitations of refining. The paper goes on to discuss the toxicity of Hexane to the environment and the effect it has on a human when consumed or absorbed into the bloodstream.
From the Paper
"Now let us understand about the toxicity of Hexane to the environment. The severe toxicity of hexane in human beings remains comparatively low, even though it is a soft anesthetic. (Industrial products: Energizing Business) Hexane can get inside the human body through the lungs in case it is present inside the air one breathes. It has also the possibilities of entering the human body through the stomach as also the intestines in case it is present in the water we drink or food we eat or can pass through the skin in case one comes into contact with it. The quantity that the hexane goes into the human body is dependent on the degree one is exposed and also its amount. While we inhale hexane, it gets into our bloodstream and is transmitted to every other organ of the body. Hexane is broken down by the liver. In case of one gets exposure to high concentrations of hexane ranging over an extended period of time, one of these breakdown products might entail damage to the nervous system of humans. "

Abstract
This paper discusses how engineering encounters many surfaces that posses vast quantities of irregularities and application of fundamental theories neither proves practical nor precise in obtaining true representations due to these irregularities. The paper further discusses how there exists a need for accuracy in thermo-physical property data in both industrial applications which demand a reliable method of determining data. According to the paper, this need can be met by the establishment of the optical/thermal scattering facility at the University of Central Oklahoma. The paper then reviews the advantages and disadvantages of this research program.

From the Paper
"This project also plans to augment the radiative heat transfer science behind this experimentation. The Hemispherical Scatterometer will be constructed based on the most widely used methods for solution of the radiative transfer equation (RTE) and the discrete ordinate method (DOM). Despite the fact that there has been a wide construction of similar apparatuses for BRDF determination [4,15,17,18,33-35,40,43-46] there has not been any device that makes use of the quadrature scheme of the DOM to obtain this property. By using the DOM theory, commercial computational fluid dynamic (CFD) software can be easily incorporated to develop new research and/or mathematical models. These involve heat transfer problems to be compared with standard or previous models. Another aspect where the PI's project will certainly have an impact on the community is in the surface and cataloging of pattern recognition of the mentioned surfaces. Many surfaces in engineering, specially the ones dealt in this project will perhaps contain roughness characteristics similar to the ones shown in Figure 4. Even though is a very smooth material (looked through one's eye) theoretical prediction of reflectance or surface properties is not feasible. However, performing cataloging and pattern recognition is a method that will allow us to recognize intrinsic features of materials and provide a deeper knowledge of material's use and extended applicability. At the same time possible complication while using textbook calculations comes from the fact that they take the surface to be an homogeneous material rather than, say, a layered structure without considering subsurface complications or they are too cumbersome to apply. Therefore, the result is that actual measurement of the reflectance function is the best way to determine this radiative property and measure it in such manner that could also be applied to radiation heat transfer solution method or any other industrial application. This is again, where this project takes the lead."

"When electricity is applied to the OLED (around 2 to 10 volts), the electrical current is received by the cathode and gives electrons to the emissive layer. At the same time the anode also receives an electric current and it sucks electrons from the conductive layer. This creates "electron holes" between the emissive and conductive layers, which are then filled up. This is the step which creates light. To create brighter light, it is only necessary to increate the electrical current. To create colors, several OLED layers are used which contain color components for red, green, and blue (Freudenrich, n.d.)."

"Nanotechnology is important because it has great potential. According to an article entitled "Is Nanotech Getting Real" the technology could allow for the creation of materials that are stronger than steal but do not weigh as much. This would be important for the automobile, airline, and shipping industries and the environment because it could lead to the creation of vehicles that are more fuel efficient ("Is Nanotech Getting Real")."
