Abstract
This paper discusses how 1905 proved to be the most significant year in Einstein's development of theory. The paper explores the reasons why the science world was reluctant to accept his ideas. It explains that the world had been accustomed to theories in science that were believed to be the complete answers to concepts.
From the Paper
"1905 proved to be the most significant year in Einstein's development of theory, according to Lightman. The world had been accustomed to theories in science that were believed to be the complete answers to concepts that would remain as cornerstones of the scientific community for eternity. This is why that when the publication of Einstein's 5 seminal papers occurred the professionals within this community were reluctant to accept any of the young patent clerk's ideas. Lightman contends that it took nearly four more years following the publication of the papers before the scientific community began to realize that Einstein's theories demonstrated answers to questions that had only been explored. Lightman describes the 5 seminal papers by stating, Two provided definitive new evidence for the existence and sizes of atoms and molecules; two proposed a radical new conception of time and ..."

Abstract
The paper handles the physical issues of drag and terminal speed within the context of throwing and kicking a football. The paper approaches the topic as if the world on the surface of the earth is a uniform fluid and anything moving through this fluid is subject to the force of drag. Accordingly, the paper explains that moving footballs must deal with these forces in specific ways in order to travel the greatest distance.
From the Paper
"Any time an object moves through a fluid it is subject to a retarding force acting opposite to the direction in which it is traveling. This force is called drag and since our atmosphere is essentially a fluid, every object we observe to be moving relative to the atmosphere is experiencing drag. Generally, drag tends to reduce the speed of any moving object and in some situations is just considered to be friction. However, quite unlike friction, "The drag force increases as the speed of the object increases," (Tipler 133). In fact, "At low speeds, the drag force is approximately proportional to the speed of the object; at higher speeds, it is more nearly the square of the speed," (Tipler 133)."

Abstract
This paper compares two technologies, photovoltaic cells and solar thermal power plants, both providing energy from solar radiation, but by different means and in different degrees. It looks at how the photovoltaic cell is used in limited situations for powering small appliances and how solar thermal power plants are able to produce much more energy for use on a widespread basis by consumers, industry and entire countries. The relative costs are noted, along with economies that will be realized once these systems are more widely used.
From the Paper
"This report summarizes two related technologies, the photovoltaic cell and the solar thermal power plant, both methods of producing energy from solar radiation. The photovoltaic cell is used in limited situations for powering small appliances, and solar thermal power plants are able to produce much more energy for use on a widespread basis by consumers, industry, and entire countries. The relative costs are noted, along with economies that will be realized once these systems are more widely used. Introduction One of the great unknowns in American energy policy remains the extent to which solar energy in its various forms will contribute to the nation's energy supply in the future. After the oil, embargo in 1973, considerable interest was expressed in solar energy as a potential way of producing energy and of reducing dependence on foreign oil. "

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."

Albert Einstein, 2005.
This paper analyzes Albert Einstein as a famous scientist and cultural icon.
2,475 words (approx. 9.9 pages), 6 sources, $ 97.95
»
Click here to show/hide summary
Abstract
The paper discusses how Albert Einstein's scientific genius rendered him the most famous scientist of the 20th century but contends that his intense humanism probably resulted in his status as a cultural icon. The paper relates that it is sometimes not realized that Einstein lamented his breakthrough in relativity and the splitting of the atom that permitted the Allies to create the atomic bomb that ended World War II and heralded our nuclear age.
From the Paper
"Much rhetoric has been written on how scientific discoveries reshape a period and sometimes an entire culture. Gerald Holton notes that Einstein's scientific papers on relativity, statistical mechanics and quantum physics in the first two decades of the 20th century, "caused remarkable and sometimes quite unforeseen cultural transformations and resonances" (p. 125). Of course, Albert Einstein is credited with the theory of general relativity to revolutionize the sciences into the 21st century and the new orientation of relativity would strongly affect the social sciences, plus the world of arts and letters."

Abstract
This paper examines the history of science in terms of changes in astronomy from the time of Ptolemy to Galileo, based on the book "Science without Limits" by James Perlman. The writer notes how the ancients saw science as a form of philosophy, while by the time of Galileo, observation was being joined with experimentation to examine concepts and find the truth.
From the Paper
"The history of astronomy shows the development of science as a discipline from the ancient world to the Renaissance, from the time of Ptolemy to the time of Galileo. Over that period, astronomy began to shift from a philosophy to a science. Science in the ancient world was not created out of whole cloth and was based on observations and the application of reason. Mathematics were also used to develop ideas about the universe. Mathematics is itself an application of reason, though aspects of mathematics have also been developed through observation and testing. By the time of Galileo, however, science was gaining a more experimental structure, and Galileo himself tested many ideas directly. His astronomy was also based on observations, but he was able to observe more directly and closely with the telescope. Perlman notes that "science in large part . . . is a matter of testing assumptions"."

Abstract
This paper discusses the theory of matrices, how it was developed, how it changed, some of the applications for which it has been used, and other aspects of the issue. The writer notes how the underlying ideas are ancient and began with the Babylonians and Chinese and then resurfaced in the seventeenth century with the world of Cayley and others. Further the writer points out that the theory of matrices has led to uses in physics, chemistry, and economics as well as mathematics.
From the Paper
"Matrices are a means of visualizing mathematical concepts and relationships in graphic form. A matrix is a rectangular set of elements viewed as a single entity, identified by the number of rows and columns of which it is made. Matrices can be added or multiplied on the basis of an algebra of matrices, and one application of this sort of operation is seen in vector analysis and in the solving of systems of linear equations. The basis for the matrix is found in the Cartesian system of Rene Descartes, whose contribution to mathematics was in the development of analytical geometry, closely tied with the development of the Cartesian system of mapping on a grid or graph, for Descartes saw that a function or polynomial can be represented graphically by points."

The Sun, 2005.
This paper discusses how the sun is able to produce visible light.
1,125 words (approx. 4.5 pages), 5 sources, $ 44.95
»
Click here to show/hide summary
Abstract
This paper examines the nature of the sun, the nature of light and how they are connected. The author points out that the connection lies in nuclear fusion, the process in the core of the sun by which incredible amounts of energy are produced during the fusion of hydrogen into helium. The paper relates that this energy exists across the EM spectrum, some of which is visible light.
From the Paper
"The process by which the sun produces visible light is truly one of the most awe-inspiring processes in the universe and is directly responsible for all life on this planet. Light itself is a form of electromagnetic radiation that the sun produces through the principle of incandescence - essentially because it's very hot (Introduction to light, 2003). But of course, the production of light is a much more complex process than just because it heats up. The process by which the sun produces light is connected to nuclear fusion and Einstein's famous equation, E=mc2."

Abstract
This paper explains Isaac Newton's stature as the central figure in the cultural phenomena of Newtonianism. The author points out that it is evident that Newton's role in popular culture has been defined primarily through the greater but often superficial popular understanding of science, which his contributions to science generated in the public consciousness. The paper relates that, for example, while the primary thrust of Newton's published theory of matter has always been reasonably understood, a number of misinterpretations and distortions have arisen, which have had both scientific and cultural consequences.
From the Paper
"In analyzing Isaac Newton's stature as the central figure in the cultural phenomena of Newtonianism, it is evident that Newton's role in popular culture has been defined primarily through the greater but often superficial popular understanding of science that his contributions to science generated in the public consciousness. For example, while the, "primary thrust of Newton's published theory of matter has always been reasonably understood," a number of "misinterpretations and distortions" have arisen, (Dobbs 2) which have had both scientific and cultural consequences."

Abstract
This paper describes fusion and matter-anti-matter reactions as alternative energy sources. The author rates these energy sources. The paper explains that technical changes are required for their use as alternative energy sources.
From the Paper
"Energy is one of the most important issues facing human civilization. There are many alternative energy sources that are not based on fossil fuels. Nuclear fusion and matter-anti-matter reactions have been suggested as an energy source. Many researchers believe that nuclear fusion is the answer to the worlds energy needs. According to Roger O. Bangerter et al in The Fire Next Time, "Fusion takes advantage of the most powerful Force in nature, the so-called strong force, Which binds protons and neutron into atomic nuclei"(Bangerter et al. 21)."

Abstract
This paper suggests that the development of the atomic bomb is arguably the most important technical innovation of the twentieth century. The author explains the technical achievement of the atomic bomb. The paper examines some of its socio-cultural effects, namely creating a world in which the end of all human civilization became a real possibility.
From the Paper
"There will be no argument that the 20th century had been characterized by incredible technical innovation and invention. Perhaps more so than any century previously, the 20th century was a particularly ripe period for technology. At a rapidly accelerating pace, it seemed that inventors were creating new technologies that were important - and seemingly indispensable - the world over. However, there was one specific technological development during the 20th century whose development should be understood as more important and influential than the rest."

Albert Einstein, 2005.
This paper discusses the life, times and the theory of relativity of Albert Einstein.
1,575 words (approx. 6.3 pages), 4 sources, $ 62.95
»
Click here to show/hide summary
Abstract
This paper examines the confluence of human imagination and scientific inquiry that informed the work of Albert Einstein. The author notes that Einstein's imagination, which made him appear like a distracted, daydreaming and unpromising child and young adult, was vitally important in allowing him to unlock the answers to questions that had dogged scientists for generations. The paper explores the stunning impact of Einstein's Annus Mirabilis.
From the Paper
"Whether he desired it or not, Albert Einstein's name has become irrevocably linked with physics in the Twentieth Century. The reason for this, of course, is Einstein's Theory of Relativity, which, when first conceived early in the Twentieth Century, changed profoundly how man viewed the world and universe around him. This paper takes the opportunity to explore the stunning impact of Einstein's Annus Mirabilis and, much more importantly, emphasize how Einstein's oft-misunderstood creativity - a creativity that was confused with aimlessness by his elementary school educators and university instructors alike - was at the heart of his mathematical genius."

Nanotechnology: A New Revolution, 2006.
A look at nanotechnology as the new revolution.
2,624 words (approx. 10.5 pages), 8 sources, MLA, $ 79.95
»
Click here to show/hide summary
Abstract
This paper takes a look at nanotechnology and reviews the possibilities of nanotechnology possessing the properties to become the next revolution. This paper also discusses the speech "There's Plenty of Room at the Bottom" given by Nobel Prize winning physicist, Richard Feynman, disagreeing that the laws of physics do not control man's capacity to control single atoms and molecules.
From the Paper
"It has been said that with creation comes destruction. Technology has yet to perfect rational within nanotechnology. However, if a nanomachine with the capability of logical reasoning is developed, one must speculate whether or not nanotechnology can possess the properties to become the next revolution. Forming a new revolution can alter the way the society lives economically, scientifically, and in many other ways. In essence, nanotechnology with the capacity of logical reasoning can have the capability to become harmful instead of good, striving to bring out the destruction of its creator."

From the Paper
"Americans had longed dreamed of harnessing the power of Niagara Falls, but schemes for extracting power from the Falls never materialized. Tesla had dreamed since childhood of harnessing the power of Niagara and this dream came true when Westinghouse was awarded the contract for creating a powerhouse there. The Niagara Falls Power Project came as a result of a failed competition led by the Niagara Falls Commission, charged with planning the power project. They had solicited proposals from experts from around the world but rejected all ..."

The writer then discusses the transport of large molecules into cells. In this paper, the writer examines thermodynamics and enzymes. The writer alos presents technical information in this regard.
From the Paper
"Osmosis is the process of diffusion of water molecules across a membrane. The contents of cells are basically solutions of many different solutes and the more concentrated this solution is the more solute molecules there are in a given volume and the less water molecules. Water molecules can diffuse freely across a membrane but only down a concentration gradient so water always diffuses from a dilute solution to a more concentrated solution. Osmosis can be quantified using water potential so it is possible to calculate ... "

From the Paper
"The scientific method is the process by which scientists collectively over time construct an accurate representation of the world. The first step is to observe and describe some phenomenon which is of interest. Next a hypothesis is developed to explain the phenomenon. In the third step, the hypothesis is used to make predictions about new phenomena or the results of these new phenomena. Fourthly, these predictions are tested by experimentation or further observation. Steps three and four are then repeated until consistent results are obtained. This often ... "

Abstract
This paper explores the fate of the universe. The writer looks back to the origins of the universe to see how it all started and what has been happening since then. In this article the writer explores some of the predictions for the future, the main one of which is that the universe will go on expanding forever.
From the Paper
"Before one can speculate on the fate of the universe, one must first look back to how it began. The modern version of the 'Big Bang' theory is that a massive explosion created all the mass and energy in the universe and also the fabric of time-space, which inflated rapidly after the big bang but then slowed down and the universe cooled down. The temperature dropped within minutes and free-roaming quarks formed protons and neutrons, some of which coalesced into the nuclei of simple elements."
