Conclusion
From the Paper
"As noted earlier, most nuclear power plants are based on the "fission" process. During various stages of the 'fission' nuclear cycle there is a high level of radioactivity present. Nuclear weapons can also be made from the nuclear fuels uranium-235 and plutonium-239. These two facts have prompted a public outcry against the use of nuclear energy, even for peaceful purposes. An accident at the Chernobyl (located in the then USSR) power plant in 1986 and a 1979 incident at Three Mile Island nuclear power plant (near Harrisburg, Pennsylvania) further reinforced these concerns. As a result, the use of nuclear energy has declined in the US and most of the world during the last several years. In my opinion these concerns about the peaceful uses of nuclear energy are overblown and nuclear energy deserves a second look as a solution for the ever-increasing energy needs of the world."

Abstract
This paper discusses robotics, a technology that deals with the design, construction and operation of robots that are used in numerous applications. It looks at how these applications range from industries that require accurate and repetitive tasks (such as the car and computer manufacturing industries), dangerous tasks such as diffusing of bombs and other chores that cannot be performed by humans, e.g., carrying out research on far-away planets, or walking inside live volcanoes. It provides a description of what robots are and how they work, the history of robotics, the present applications of robots, the impact of robots in our lives and their limitations as well as the future of robots. It also discusses how close we are in the development of a 'bionic' man.

The Future of Robotics
Conclusion
From the Paper
"Although robots as we know them today are a relatively recent invention, the idea of automated machine or a mechanical man has fascinated the human mind since the ancient times. For example, the ancient Greek poet Homer in his writings described maidens of gold, who are supposed to be mechanical helpers built by Hephaistos, the Greek god of metalsmiths. Similarly, in ancient Jewish legend, robot-like servants made of clay are brought to life by a spoken charm. (Tesler) In more recent times, Leonardo da Vinci, the "Renaissance man" drew plans for a mechanical man. Eighteenth century watchmakers were also famous for making mechanical, robot-like creatures.

Abstract
This paper examines how nuclear power is one of the most divisive issues in America today and how opponents of nuclear power have succeeded in convincing people to oppose the construction of new plants and to fight the relicensing of old plants. It puts forth some of the arguments from both sides to support their positions and looks at issues such as the question of safety and need for nuclear power plants and the of storing nuclear waste. It analyzes how proponents of nuclear power present convincing arguments for the continued and expanded uses of nuclear power in this country and how they claim that the objections raised by opponents lack validity and are contrary to the facts and our experience.
From the Paper
"The opponents of nuclear power focus on the inherent lack of safety that they believe that the use of nuclear power entails. This includes both the dangers of radiation from nuclear power plants and the possibility of a catastrophic accident. First, the opponents say that radiation levels are higher in areas around nuclear power plants, and this leads to an increased number of deaths from cancer. They cite the case of the Pilgrim Nuclear Power Station in Plymouth, Massachusetts that went online in 1988. Responding to the concerns of local residents, the state conducted a study which found that there were fifty percent more cancer cases in the five towns around the plant than there were in the rest of the state. The power company had said that people in the area would receive 400 times less radiation from the plant than they would from natural sources. Further studies showed that the risk of getting cancer was four times higher for people living within ten miles of the plant than for other parts of the state. "

The Anthropology of Sound, 2002.
The history and development of the understanding of sound from an anthropological perspective.
3,148 words (approx. 12.6 pages), 10 sources, MLA, $ 91.95
»

Abstract
This paper discusses sound from an anthropological perspective and concentrates on the origin and the nature of sound. The paper also reviews on how the study and the development of sound progressed with technology. It also concentrates on the association of sound with language and culture and shows how the pronunciation of words have resulted in different sounds with the development made in the writing scripts. The paper also lays emphasis on the association of sound with memory called echoic memory.
From the Paper
"People love sound and sound today is ubiquitous; sound will continue to fascinate people for ages to come. The pleasures of sound flow from frequency, amplitude and harmonic constitution or waveform. Perhaps there is no other form of art where the pleasures of mere form are more marvelous in complexity, more intellectual in essence and purer in quality. Plato once suggested that the sensibility for sound might be the most civilizing of educational instruments. People and sound both belong to each other and both grow out of life."

Bell's Inequality, 2002.
An insight into Bell's Theorem (Bell's Inequality) of quantum theory.

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 Eternal Circle of Time, 2002.
An examination of the apparant "Cause and Effect" order of the universe, and the roll "Time" plays in this order.

»
Click here to show/hide summary
Abstract
This paper attempts to suggest an answer to the question of governace in the universe. It looks at what may seem to be a hirarchial order of "Cause and Effect", which sees every event as the result of a previous one and at the same time the cause of another event. As we go further back into the very begining it appears that "Time" itself is the essence of it all.
From the Paper
"While not a popular theory among modern historians and philosophers, the idea of the Great Chain of Being does offer an explanation for the harmonies and interrelationships that exist within the universe. Nothing can occur without a prior cause, and each preceding event is the reason for the following event. . . Therefore, there must be an overall order, an overall rhyme and reason to the universe and all that is contained within it. Time does indeed have a purpose, and its purpose is the eternal cycle of birth, development, and regeneration."

Abstract
This paper explains that by viewing the gas that surrounds stars as a dynamic atmosphere, undergoing cycles of materials similar to those that go on in the Earth's own protective gases, astronomers are understanding more and more about the processes involved in the formation of stars. The paper deals with the questions of how the supernova of massive stars affect the formation of stars in the future, why star formation seems to occur in relative bursts, and how long the Milky Way will continue to produce stars.
From the Paper
"Beyond applying the atmospheric model to intergalactic gas, astronomers have also been studying more carefully exactly what components make up the gas and at what temperature these components exist. About 90% of the constituents of intergalactic atmosphere are various forms of hydrogen, with close to 10% being helium, and everything else, from lithium to uranium -- the whole spectrum of the periodic chart -- making up less than 0.1%. The majority of the hydrogen is present as neutral hydrogen, termed H I by astronomers. This form of hydrogen gas is identified by the spectral frequency of the light that it emits, namely 1,420 megahertz. Although scattered throughout the galaxy, the majority of H I is located around the galactic midplane, and forms a gaseous disk about 300 parsecs thick (Reynolds, 2002, p. 40)."

Abstract
This paper looks at black holes in terms of the most prevalent theories. It first, defines what we have come to understand as a black hole. It then touches upon how black holes are documented and measured. Thirdly, it examines the black hole believed to be at the center of our own Milky Way galaxy. Finally, it explores the prevalent hypothesis that black holes are in fact the genesis of all galaxies.
From the Paper
"Gravity is the cause of black holes. A black hole is the unlimited and irresistible force of ultimate gravity in the universe. To understand how a black hole is created, it is helpful to understand a bit about the basics of gravity. Imagine shooting an arrow into the sky. The harder you shoot the arrow, the farther it will go in attempting to escape the pull of the Earth's gravity. If you were to use a big enough bow with enough force you could help the arrow reach speeds exceeding 7miles per second which is the escape velocity for the Earth. Escape velocity indicates the minimum speed necessary to beat the pull of the planet's gravitational core (Cowen , 390). The strength of the gravitational pull of the core is determined by the density and mass of the core. The denser and more massive that the core is, the greater the gravitational pull. If you were to drop a ball to the center of the earth, the gravitational forces would crush it into an ever shrinking volume requiring even greater amounts of force to help it reach escape velocity. As the greatest theoretical speed for any physical object in the universe is that of light (which travels at 186 thousand miles per second) a mass large and dense enough can actually exert so much force that not even light can achieve escape velocity. The object that can pull even light into it and keep it from escaping is a black hole."

Abstract
This paper begins by providing a brief biographical overview of Isaac Newton, from his birth in England in 1642 to his groundbreaking scientific theories and discoveries. The paper covers Newton's scientific achievements, starting with the fact that he established a unified theory of approach to modern science. It discusses his discoveries relating to the white light, the telescope and to the field of optics in general. The paper also covers Newton's mathematical achievements in the form of calculus and his most famous discovery of all - gravity.
From the Paper
"Newton's discoveries in optics were offset by his even more groundbreaking discoveries in pure mathematics and the science of mechanics. One of the most important modern mathematical tools 'The Integral Calculus' was the brainchild of Newton. It need not be mentioned that without this mathematical tool the progress that the scientific community achieved in many disciplines would have been significantly delayed. However Newton's discoveries in the field of mechanics outweigh all his other accomplishments. Though Galileo had already discovered the first law of motion his theory was based on the movement of objects without any external influence or attraction between them. Newton's three laws of motion explained the hitherto inexplicable behavior of all physical bodies in motion. Still more astounding was Newton's discovery of gravity. All these four laws put together explained the mechanical motion of all earthly and heavenly bodies. Newton not only proposed these laws but also ratified them by using the integral calculus."

Abstract
The paper begins with some introductory remarks about the science of physics and by attempting to clear up some misconceptions regarding the way that pitchers throw balls. It then turns to discuss the storage of baseballs in a giant humidor and the effect of humidity on the motion of baseballs. It explores the materials used to make baseball bats and looks at their velocity. The paper concludes with an explanation of the new computer system introduced for the 2002 baseball season and a look at the involvement of physicists and engineers in evaluating this system.
From the Paper
"According to some scientists, pitchers would defy the law of physics if the balls were actually thrown the way they were described. These scientist say a curve ball doesn't actually curve, just appears to do so. They also say a rising fast ball is mislabeled "since a ball thrown overhand can't rise (NPR, 1993)." They say players and announcers are incorrect when they say a ball hops, slides or hisses, since it is scientifically impossible, though they will admit a ball can sink a little. Scientists are quick to point out that a waist-high fast ball doesn't actually rise when it hits your chin, but the hit occurs because the ball doesn't fall as much as you predict it will. Announcers and players will disagree with these physicists, however, because they accept these concepts on faith and not science (NPR, 1993)."

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."

Abstract
This paper discusses the life and work of Isaac Newton and how his laws and discoveries have ensured that his name is imprinted in the history of science. The author illustrates how Newton is not only one of the greatest scientists but also one of the most influential scientific personalities.
From the Paper
"Isaac Newton was the greatest and the most influential scientist of all times. Born in Woolsthrope, England on a Christmas day in 1642 Newton was a bright child with an incredible mechanical aptitude. Newton entered the Cambridge University when he was eighteen years of age and soon he mastered the science and mathematical concepts of his time and went on to continue his independent research. It was during this period that Newton laid the foundation for the subsequent discoveries that were to revolutionize the scientific world. Newton was conferred the honorable Fellow of Royal Society of London in 1671."

Abstract
This paper describes the book, "Life of Isaac Newton" by Richard Westfall, which tells chronologically the life of a solitary scholar, Trinity College professor, government administrator and elder statesman of the English scientific community by showing his accomplishments and human weakness. This paper tells the story of the "apple" and points out that Newton may have gotten the idea when he was young but it took many years for him to develop his theories.
From the Paper
"For a number of years, Newton did not publish anything and seemed to immerse himself in the study of chemistry and its "occultist" neighbor, alchemy. Avoiding the more mystical areas of the science, there is no doubt he was searching for both knowledge as well as gold . Newton also was delving into some dangerous theological areas, doubting the existence of the Trinity and attributing it to a corruption of the true earlier Christian religion. Despite holding these beliefs until his death, he successfully kept them a secret, and even managed to be appointed to the Lucasian chair of Trinity College without having to take the usual step of taking on the holy orders. He kept his then-heretical religious beliefs a secret until his deathbed, when he refused to take his final communion "

Nuclear Energy, 2002.
An indepth overview of nuclear energy and its uses.
4,609 words (approx. 18.4 pages), 10 sources, APA, $ 119.95
»
Click here to show/hide summary
Abstract
This paper examines one of the most promising energy resources being currently explored, nuclear energy. It shows that the idea of using nuclear energy is being used to scare mankind, because at the time the only connection one had with nuclear energy was nuclear weapons. In recent years however, there have been efforts to explore the use of nuclear energy for the purpose of sustaining life. While there are questions about its safety and use, it is quickly becoming evident that nuclear energy is going to be the wave of the future. This paper takes the reader on an exploratory journey of the issues surrounding nuclear energy and the positive as well as negative aspects of the topic.
From the Paper
"The first alert came by way of Three Mile Island, in Pennsylvania (Siegel, 1991). The threat of a melt down that occurred there caused a nationwide panic and a first time anger at the fact that law makers had allowed nuclear energy to be used(Siegel, 1991). Just as those concerns finally were laid to rest the incident at Chernobyl occurred. If Three Mile Island was the cake, the accident at Chernobyl was the frosting and after it killed dozens of people, destroyed countless miles of land for the next few centuries and exposed millions to fallout symptoms for the next several generations America firmly put its foot down and began to demand the slow and stopping of all nuclear power activity in the states."
