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 "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")."
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 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 essay examines and discusses the impact of World War II on the development of science and technology. The discussion includes several examples, mainly pertaining to the development of nuclear science, weapons, medical research and genetics. The writer points out that since the end of World War II there has been an almost complete merger of science and technology, and governments and the industry now support most pure science research. Further, the writer notes that according to McClellan and Dorn, the example of the atomic bomb development in the US during World War II marks a watershed in the history of modern science and technology.
Abstract This paper explains that the scope of the effect the dropping of the atomic bombs on Hiroshima and Nagasaki had on modern warfare and science technology is visible only when taking into account the intense scientific processes to create these weapons of mass destruction. The author points out that, at the dawn of World War II, Albert Einstein sent a letter to President Franklin. D. Roosevelt about Nazi Germany's efforts to purify uranium-235, which he warned could result in the building of an atomic bomb. The paper relates that, soon after this letter, the U.S. government started the Manhattan Project to develop the atomic bomb before the Germans. The author states that the bomb was tested successfully on July 1945 and, a month later, the first bomb was dropped on Nagasaki. The paper concludes that the atomic bomb was considered a "quick" and economical way to win the war; however, it was a cruel form of punishment for the Japanese citizens resulting in slow and painful deaths for many innocent Japanese. The paper includes graphs.
From the Paper "The most difficult part of the Manhattan Project was how to produce enough enriched Uranium to uphold a chain reaction. Uranium-235 was hard to extract. Only about 1/500th of Uranium ore mined ends up as Uranium metal. Of this metal, the fissionable isotope of Uranium is rare. Fissionable Uranium occurs at a ration of 1 to 139. Separating one part of Uranium-235 from 139 parts of Uranium-238 is challenging. Only mechanical methods could effectively separate the two. Scientists at Columbia University first figured out how. A facility to separate Uranium-235 was set up in Oak Ridge, Tennessee."
Abstract This paper discusses how fossil fuels are running low on supply and renewable energy has yet to be realized, as well as developed. The paper then looks at the one power that is safe and abundant - nuclear energy. The paper contends that nuclear energy be realized as a fuel for the future and be developed enough so that the world can thrive in its abundant energy.
From the Paper "It has been said that the power to regulate is the power to destroy. This has certainly been the experience of the nuclear industry. Regulation of many industries increased rapidly during the 1970s. In 1970 when Maine Yankee was being licensed, there were 91 permits to be obtained including, for example, a permit to discharge sewage. By 1975 this had risen to over 400 permits per plant (Duffy 165). But there are only two regulatory authorities of importance: the Federal Nuclear Regulatory Commission (NRC) and the various state Public Utility Commissions. The NRC regulates safety, including radiation safety, although that is often delegated to the states. They are sensitive to public opinion and have often been very assertive of their power and their duty. "

Abstract This report is designed to introduce the future officer to traffic radar. It explains to the future police officer the kind of radar units he/she may encounter on a job, how they work, public opinion of them and touches on the potential health hazards that radar units can present.
From the Paper "Since its introduction to traffic law enforcement in 1948, radar has been an integral component of vehicular speed measurement. Each year hundreds of thousands of dollars are collected in courts throughout the nation from motorists whose speed was monitored with the aid of this electronic instrument. Today, radars overall efficiency and effectiveness have been greatly enhanced. In spite of its great improvements, radar is currently being scrutinized, questioned, and challenged, not only for its reliability but also for the quality of operator training. "
