Abstract
North Korea has been intimidating the United States with a series of nuclear threats since October 2002, when U.S. officials stopped the supply of heavy oils to the North in retaliation of its confessed production of nuclear warheads, violating agreements signed in 1994. Shortly after, North Korea withdrew from the Nuclear Nonproliferation Treaty (NTP) and agreements with the United Nations. The paper shows that while there is little proof that North Korea has nuclear weapons, it is strongly suspected that it does. The paper discusses the North Korean weapon issue.

From the Paper
"Many world leaders are suspicious about North Korea's withdrawal from the NPT for many reasons. For one, it is a well-known fact that countries developing clandestine nuclear weapons programs take many measures to conceal information about these programs from the rest of the world (NTI, 2003). Therefore, without membership in the treaty, North Korea has made it difficult for world leaders to obtain information about the country's weapon capabilities."

Abstract
This paper discusses alternatives to nuclear power like fossil fuels, solar and hydroelectric power and describes the problem of waste disposal at the Yucca Mountain Repository for nuclear waste.

Abstract
An argumentative paper, exploring the chemical make up of uranium, showing that it is extremely difficult to dispose of this material in a complete way. It looks at current disposal practices in the world and analyzes their pros and cons.

From the Paper
"Radioactive material is defined as having atoms with extremely excited outer electron shells. This makes them unstable, excitable and an efficient means of providing energy to a population that can afford a nuclear power plant. The main source of this energy is Uranium. This is a naturally occurring element found in rocks and seawater. It is the most heavy element in the periodic table, having 146 neutrons and 92 protons in its stable form. The instable form has 143 neutrons and this is the kind that is used in cores to create energy (UIC website)."

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
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 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
In order to make a judgement of the physics viability of nuclear power as an energy source for Australia, this paper explains how nuclear energy is produced, disposed of, sourced, and maintained in light of Australia's unique environment and population distribution. The paper discusses the efficiency of using nuclear energy as well as Australia's huge availability of uranium and its ample waste storage space. The paper concludes that nuclear energy is definitely a viable method of energy for Australia but recommends that stringent laws and regulations be made to enforce adequate training of nuclear staff to minimise the risk of disasters. The paper includes a diagram of how nuclear power is produced and a map of mining locations in Australia.

From the Paper
"Nuclear energy is generated by the fission of the uranium 235 isotope. U-235 is the ideal fuel for power generation because it is able to sustain a chain reaction and release energy. Uranium for fuelling nuclear generators is mined in Australia as low-grade ore. Only 0.3% of this ore is pure uranium, and after crushing, chemical treatment and concentration, only 0.7% of this residual is the required U-235 isotope. In order to ensure an induced chain reaction is sustainable, this nuclear fuel needs to be enriched (i.e. concentrated) so that the U-235 concentration is approximately 5%. (Rapkins, Rossiter, Walding, 1999)"

Abstract
This is a detailed study describing the progression of the Manhattan Project and the invention of the atomic bomb. The "Manhattan Project" was a code name given to the efforts and collaboration of many scientists to build the first atom bomb. The author sees two major challenges that faced the team of highly capable scientists. The first was the actual production of the atom bomb. This involved actually making innovative discoveries that would revolutionize war and change man's idea of war for good. The second involved all of the ethical debates on whether or not the bomb should have actually been used in warfare. The author concludes that the building of the atomic bomb proved to be the most pivotal advance seen by science up until the early twentieth century.

From the Paper
"We have too many men of science, too few men of God. We have grasped the mystery of the atom and rejected the Sermon of the Mount...The world has achieved brilliance without wisdom, power without conscience. Ours is a world of nuclear giants and ethical infants. We know more about war than we know about peace, more about killing than we know about living..." stated General Omar N. Bradley, Chief of Staff of the United States Army in 1948, voicing the opinion, shared by many of the time, towards the building of the atomic bomb. The "Manhattan Project" was a code name given to the efforts and collaboration of many scientists to build the first atom bomb. There were two major challenges that faced the team of highly capable scientists. The first was the actual production of the atom bomb. This involved actually making innovative discoveries that would revolutionize war and change man's idea of war for good. The second involved all of the ethical debates on whether or not the bomb should have actually been used in warfare. The project lasted from 1942-1946 and cost approximately 1.8 billion dollars, which is comparable to 20 billion dollars today. The building of the atomic bomb proved to be the most pivotal advance seen by science up until the early twentieth century."

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
Discusses an experiment of the shielding of radiation. The experiment uses fluid flow measurements and the method of continuous flow to determine the coefficient of viscosity. Includes the calculations and results of the said experiment as well as diagrams. Discusses the conclusions and several human errors that happened when carrying out the experiment.

From the Paper
"There are two different ways water can flow this can be either streamline or turbulent. When a liquid has a streamline its particles flow in regular and smooth paths called streamlines. In this type of motion the viscous drag opposing the flow is proportional to the average velocity of the liquid. In turbulent flow, the particles have irregular motion therefore the viscous drag is proportional to the square of the velocity. "
