Abstract
The paper addresses the question of whether the world's energy resources are becoming scarce with the impending increase of the human population. This paper analyzes the current energy resource uses, provides calculations of energy output and compares them with each other. A background of the various energy resources is given as well as an introduction to Nuclear Energy. Fission/Fusion technology is also brought up throughout the paper. An explanation of the Fission/Fusion theory is provided on how this renewable resource works.

From the Paper
"With man's leap into technological advances, one would think that the boundaries are endless. The human race has allowed to progress for over hundreds of thousands of years. Especially in the late centuries of history, mankind has excelled immensely in achieving technological success. From the discovery of electricity, to the creation of the internal combustion engine, modern society has come to a time where ceaseless change exists in everyone's lifetime. Everyday man takes another step into the ladder of intellectual evolution. These advances still cannot guarantee happiness among society. For all of these things are dependent on one thing, energy. Energy is needed to maintain life in all things, from the plants of the Amazon forest, to the fuel burning inside of a Toyota Camry. Without it, all living things would cease to exist, including the humans who created this ever growing technology. One might speculate that with the extreme rate at which the population is increasing, all the resources on earth would become scarce. But an energy crisis is hardly anything for a person to worry about, for humanity has taken a step into the discovery of nuclear power."

Abstract
This paper explains that going back in time to visit historical times in real life may sound like the work of an H.G. Wells novel, but physicists are getting surprisingly closer to actually being able to travel in time, as demonstrated by the theory of relativity, light speed, paradox theories, and the work of modern scientists as they search for the secrets to the 4th dimension. The author points out that Dr. Stephen Hawking's theory and the recent discovery of black holes show the potential for an area where the laws of relativity may not exist. The paper relates that Dr. Ronald Mallett at the University of Connecticut has developed an idea that present-day people can communicate with the past by sending electrical particles through a spiral series of laser beams to accelerate them to the speed of light.

Conclusion

From the Paper
"The Theory of Relativity states that fundamentally our ideas of space and time. We must accept that time if not completely separate from and independent of space, but is combined with it to form an object called space-time. Newton developed laws of motion that until Einstein were not contested. Einstein expanded this law in his special theory of relativity, which states that mass increases as speed approaches the speed of light. We must remember that the more mass we have the larger that mass will become as light speed is reached. The speed of light and time space is closely related. It has been said that light speed is the key to time travel. At this time the theory of relativity limits our ability to move mass at the speed of light, but as I will explain, there are current theories that will allow moving electrical energy in the form of data back in time."

Abstract
In order to better understand the issue of solar energy, this paper presents a definition of the terms and concepts relating to solar energy. The paper examines the technologies that are currently used to put solar energy to work. A short historical background on the development of solar technology in the past sixty years is presented. The paper explores the reasons why it is important to develop solar energy and discusses its future costs and benefits.

From the Paper
"Solar energy is radiation from the Sun that can produce heat, generate electricity, or cause chemical reactions. Solar energy is inexhaustible and nonpolluting, but it is not an efficient energy source, since the Earth's atmosphere absorbs or scatters over 50% of incoming solar radiation. Solar collectors collect the radiation and transfer it as heat to a carrier fluid. It can then be used for heating. Solar cells convert solar radiation directly into electricity, by means of the photoelectric effect.
Very often, there is confusion about the various methods used to harness the sun's abundant and clean energy. Energy from the sun can be categorized in two ways: in the form of heat (or thermal energy), and in the form of light energy. Solar thermal technologies use the sun's heat energy to heat substances (such as water or air) for applications such as space heating, pool heating and water heating for homes and businesses. There is a variety of products on the market that utilize thermal energy. Often the products used for this application are called solar thermal collectors and can be mounted on the roof of a building or in some other sunny location. The sun's heat can also be used to produce electricity on a large utility-scale by converting the sun's heat energy into mechanical energy. "

Abstract
This paper discusses how black holes are created. It studies the ideas of physicist John Mitchell, his discoveries and how Isaac Newton's physics ideas helped lead to his discoveries on black holes. It also covers white dwarfs (stellar corpses), the most famous being Sirius.

From the Paper
"The black hole was first named by the English physicist John Mitchell in 1783, more than two hundred years ago. But what are these black holes? Do they really exist? Based on planet movement studies made by Tycho Brahe and Johannes Kepler, John Mitchell deduced the existence of a force that made the Sun, the Earth, the Moon and everything contained in the cosmos."

Abstract
This paper explains how a nuclear reactor produces energy. The paper includes a discussion of fission, radioactivity, types of reactors and how they produce electricity.

From the Paper
"All modern nuclear reactors operate on the principal of nuclear fission. Nuclear fission is a process in which the nucleus of an atom is split when it absorbs a free neutron after a collision occurs between the atom and the neutron. Splitting the nucleus of the atom releases large amounts of nuclear energy contained within the nucleus. Once the nucleus of the atom is split, multiple neutrons are released which are used to split nuclei of other atoms, causing what is known as a chain reaction. The chain reaction will continue as long as an average of one neutron per fission is absorbed by a nucleus. By harnessing and manipulating the energy that is released, other types of energy can be obtained. The power developed by nuclear fission has been used by man to create, as in the driving of an electric generator and for propulsion, as well as destroy, as in the release of atomic explosion. Whereas the fission in a nuclear reactor is precisely controlled to prevent a nuclear meltdown, the fission in an atomic explosion is not controlled and the shock wave produced by the splitting atom and its resulting chain reaction is equal to several thousand tons of TNT."

Abstract
This paper is an examination of nuclear energy as a power source, focusing on the environmental impacts associated with producing and using the fuel. The history of the development of nuclear technology is briefly discussed. Then some of the positive attributes associated with nuclear power are given, as an argument for having pursued this technology despite its many uncertainties and pitfalls. Next, the many drawbacks commonly associated with nuclear power are presented, including the problem of radioactive waste. The paper concludes with a short look into what the U.S. government is doing to address the situation created by the nuclear industry and the areas in which it falls short of solving the problems at hand.

From the Paper
"Safety concerns have rightly plagued the nuclear industry since its inception. On one front, there is the threat of nuclear proliferation, which has already become a reality with feuding countries like India and Pakistan, both possessing nuclear capabilities. This poses a major threat to the global population as well as the global environment. If even one of these weapons were to be detonated, the immediate impact on human and other biological life would be devastating. But the long term effects to the ecosystem are assumed to be equally as grave and ruinous."

Abstract
The purpose of this paper is to introduce, discuss and analyze the topic of gasoline prices in the United States and offer some insight as to why they are so high. Specifically, it answers the question "Do Americans really have a right to complain?" It also discusses European gas prices, and why they are higher than America's, as well as some alternative fuels that might help ease gas prices in the United States.

From the Paper
"American gas prices may be higher than we have ever encountered before, but they are much lower than gas prices around the world. American drivers are spoiled. They tend to drive large, inefficient vehicles, and then rant about the high price of gasoline. They drive long distances for work and play, using more gasoline per capita than residents of many foreign countries. American drivers also rely heavily on their vehicles, rather than using more efficient and fuel-friendly alternatives, like carpooling or public transportation. We depend too much on foreign oil, a resource that is non-renewable. We need to develop more alternatives to our dependence on gasoline by researching more efficient fuels and automobiles, like the hybrids that have recently been developed by Honda and Toyota, which use a mixture of gasoline and electricity to provide better gas mileage while using less gasoline. Our dependency on oil must stop, or one day, our children will wake up to world without gasoline."

Abstract
The paper defines types of ballistics and goes into depth on terminal ballistics, velocity, and one-stop shots. The author discusses the effects and actions of the projectile upon impact of a target specifically the human body. What happens when a bullet strikes human flesh? Dismisses several theories in the field using FBI research.

From the Paper
"The study of the firing of projectiles, their flight and how they strike a target is called ballistics. There are several categories of ballistics including internal ballistics, external or exterior ballistics and terminal ballistics. Internal ballistics is concerned with the behavior of the bullet or projectile from the moment it is fired until it leaves the gun barrel. Exterior ballistics deals with the flight of a projectile after it leaves the barrel. One major effect of the bullet's flight is the pull of gravity, which causes the bullet to immediately drop after leaving the barrel and fly on a parabolic path. Terminal ballistics however, is concerned with when the bullet hits a target and the effects produced by that bullet."

"Background
The Big Bang Theory is an explanation for the beginning of the universe. The universe today is expanding, as can be seen in the way all matter is moving outward. Tracing this movement back through time takes all matter to a single point, leading to the view that at one time all matter was concentrated in a singularity which for some unknown reason exploded, throwing all material now seen in the universe outward from that central point. There are various corollaries to this theory, such as the issue of whether the expanding universe will continue to expand forever or will eventually reach an end point and fall back on itself. There are also various consequences of the Big Bang which can be used to determine if the theory has validity. A number of researchers have examined aspects of the Big Bang theory and developed ideas..."

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."
