Abstract
The paper gives a brief insight into atoms from the beginning of recognition of their existence by the ancient Greeks, to the ability today to create man-made ones. It discusses the chemical composition of atoms and how scientists can now predict their behavior with great accuracy.
From the Paper
"According to existing theories and experimental results, the Big Bang took place about 12,000-15,000 million years ago. Within the first three minutes of the existence of the Universe, the light elements originated. Atoms came along after about 300,000 years and the stars and galaxies originated during the first million years. However, it took a while for humans to recognize atoms, although they were right before their eyes."

Abstract
The following paper discusses acoustics signals that detect the presence and location of commercially useful fish, map the ocean floor to establish the safest paths for supertankers, explore the earth?s geological formations and discover oil deposits in the ocean floor.
From the Paper
"At a bottom of the permanent thermocline or below it, water temperature is uniform. Here, the pressure of the water column due to the depth takes over. The sound speeds then increase on account of increase in pressure. (Pacific) The deep sound channel axis is between 600 and 1,200 m below the sea surface at low and middle latitudes. This is deepest in the subtropics and come to the surface in high latitudes, where sound propagates in the surface layer. (Pacific)
Sound waves can be ?trapped? in the deep sound channel and propagate in long distances. This is because these waves go through little attenuation beyond that, and this is due to geometric scattering or spread as well as minor volume scattering in water."

Abstract
This paper introduces the general study of sound, and, specifically, ultrasonic phenomena. Human versus animal perception of sound is discussed. The use of ultrasound as a diagnostic tool in humans is outlined.
From the Paper
"One of the greatest tools that man has ever had in the drive to preserve his own body is that of understanding. Particularly, through greater comprehension of the processes and logistics that facilitate our body functions, we can make further gains in aiding them where need exists. Sonic study is indicative of that very fact and, specifically, with the inception of sound exploration into the canon of physics came evidence that sound is more than just what human beings can hear. Rather, we now understand sound as acoustic energy existing in amplitudes of widely varying sizes and intensities. Further, the human ear perceives these amplitudes by translating their frequency. This frequency, a measure of the quantity of sound waves an object (i.e. vocal chords, drum skin, etc.) produces per second, may occur across an infinite range of measurements, expressed in hertz. The human ear, however, has a decidedly finite capacity for sound comprehension that falls somewhere between 20 and 20,000 Hz. Any sound occurring above that frequency is defined as ultrasonic. That is, ultrasonic phenomena are those sounds that exceed ?normal? human hearing capabilities, normal being defined as that hearing which falls within the aforementioned frequency comprehension range."

Abstract
The paper discusses dry-cell batteries which were invented as an alternative to higher leaking, long lasting batteries. Today?s advanced electronics are demanding more battery power and it is not unusual for a highly developed electronic item to go through two or three sets of batteries in a day. The paper shows that as technology advances, the stronger the battery demand and this brought about the invention of the dry-cell battery. The purpose of this technical research is to define dry cell batteries, their kinetic make-up, and how are they recycled.
From the Paper
"Recycling batteries saves the environment and ensures proper disposal. There are many programs which assist in helping individuals learns how to recycle batteries. There is one program called ?Charge Up To Recycle? which educates people on the recycling process, and the companies that recycle batteries. The objective of this program is to make everyone aware of the available services and encourage them to participate in recycling of the batteries. There are some battery recycle facilities that charge a small fee for used up batteries, but most of these facilities will take the batteries free of charge. The purpose of the battery manufacturers is to get everyone involved in recycling old batteries. Recycling batteries can be very beneficial to the air, eliminating lots of air pollution."

Abstract
The paper argues the scientific big bang theory and order in the development of our universe. It describes the hierarchy of events and the Great Chain of Being theory. In particular, it discusses the electron atom nucleus universe expands origin universe Big Bang primordial ball creation overall order. This paper is well formatted with intelligent depth to the argument of the creation of life and our planet.
From the Paper
"Electrons circle the nucleus of an atom. Untold trillions of atoms collide together and explode. The universe expands. Electrons race down the copper wires of an electric cable. The sun shines. Leaves digest the sunlight, produce nutrients, live, grow, die, and fall to the ground. The wind bears aloft the leaves, scatters them over earth and sea. The tide moves them, pushes them up into rivers where at last they settle into the mud. Salmon swim upstream; lay their eggs on the muddy bottoms of lakes and rivers. A powerful grizzly bear nuzzles the icy water of a mountain brook. His great paw sweeps into the water and catches a darting salmon. Men come; establish a city on the banks of the stream. They drive the bear off. Their boats coast upon the surface of the sparkling water. Nets plumb the frigid depths, resurface filled with salmon. The men eat the salmon. The salmon are digested, turned into fodder for a thousand other creatures and into the food that builds civilizations. Digested again, these minute particles break down into molecules, and the molecules into atoms. A lone atom floats off in the vast emptiness of space. Electrons circle the atom?s nucleus. These are cycles, yes, but wherein lays their ultimate origin? Is there a connection between all that makes up the universe? Is there a plan?"

Abstract
This paper discusses in detail the safety of the Suburban Utility Vehicle (or SUV). The author uses the science of physics and engineering and the relationship between a car?s relative mass and center of gravity to understand to understand the problems. The author states that increasing the track width is the only way to make the vehicles more stable but that may modify the appearance of the car.
From the Paper
"What can be done to remedy these concerns over the Wrangler?s design? To answer this question, one must do more than simply understand more about the safety features of this particular vehicle or of SUVs in general. One must turn to the science of physics and engineering and the relationship between a car?s relative mass and center of gravity to understand what the risks are for each vehicle and how best to potentially remedy those risk. Or, to put the question in another way, if Einstein were an auto mechanic, what type of Jeep Wrangler would he like to be riding in? How might he modify the vehicle?s design?"

Abstract
With air travel and the highways becoming increasingly congested, the need for an efficient, fast and comfortable mode of alternative travel has been felt in many countries of the world. One of the possible solutions is the Magnetic Levitation Propulsion System or high-speed trains called the Maglev train (short for magnetic levitation). The recent question mark over the safety of air travel and the fear of flying created among the general public by the events of 9/11 has renewed interest in the Maglev technology. This paper discusses how the Magnetic Levitation Propulsion System works and briefly overviews its history of development. The different types of designs developed so far, the cost of developing such systems, and the potential for its expansion and use in transportation systems in the United States and all over the world is also discussed. The author uses photographs and plan drawings to illustrate points.
From the Paper
"We all know that the opposite poles of a magnet attract while the like poles repel each other. This is the basic principle on which the Magnetic Levitation Propulsion System works. In magnetic propulsion systems, powerful electromagnets are used. The three basic components of a maglev train system are: A large electrical power source, metal coils that line the track or guide-way, and large magnets attached to the underside of the train. There is no conventional engine in maglev trains. Instead, the force for propulsion is achieved by a combination of the magnetic fields created by the electrified coils in the tracks (called the guideways) and the guideway walls."

Nuclear Energy, 2006.
An argument in favor of using nuclear energy.
1,855 words (approx. 7.4 pages), 4 sources, MLA, $ 59.95
»
Click here to show/hide summary
Abstract
This paper argues that the disadvantages associated with nuclear energy are not as great as some of the disadvantages of other forms of energy. Specifialy, the paper argues that nuclear power provides much economic growth and does not degrade the environment unless, of course, an accident of some sort, such as Three Mile Island in 1979, were to occur. The paper further argues that nuclear power is obviously a very sustainable source for the generation of electricity.
From the Paper
"In the early 1970s, the cost of a two-unit nuclear plant was about $1 billion, due to the great amount of materials needed for construction. For example, at one plant in the mid-1970's, 270,000 cubic yards of concrete, 17,000 tons of reinforcement bars, 11,000 tons of steel, 250,000 linear feet of large boring pipe, 240,000 feet of small boring pipe and 6,700,000 feet of cable was needed for construction. Presently, the cost has skyrocketed, due to inflation and the increased price of materials."

Abstract
This paper discusses the process of solar cell manufacturing and looks at each step of the process in detail. The paper describes the processing stages of chlorine-free polysilicon production and describes the purity requirements for the silicon used in solar cells. The paper also briefly looks at the changes in the solar cell manufacturing industry over the past few years.
From the Paper
"The very last step of manufacturing a solar cell is adding the electrodes (electrical contacts) and interconnection strips. Electrical contacts connect each solar cell to another, creating a solar panel, and then to the receiver of the produced current. The contacts must be very thin (at least in the front) so as not to block sunlight to the cell. Metals such as silver, nickel, or copper are vacuum-evaporated through either a photo-resister, silkscreen, or they can be deposited on the exposed portion of cells that have been partially covered with wax. All three methods involve a system where the part of the cell on which a contact is not desired is protected, while the rest of the cell is exposed to the metal. And finally, the interconnection strips are soldered into place. Flux is applied to cell interconnection strips before soldering to act as a deoxidizer. It ensures better adhesion between the solder and solar cells. This provides positive contact for an electrical current and greatly lowers the probability of the current shorting out. After applying the solder and flux, the cell surfaces need to be cleaned with a chlorofluorocarbon compound."

The Meaning of Life, 2008.
A discussion of the different views of the meaning of life.
764 words (approx. 3.1 pages), 3 sources, MLA, $ 27.95
»
Click here to show/hide summary
Abstract
This paper examines the different views--scientific, philosophical, religious--on how to tackle and how to best answer questions regarding the meaning of life. The paper explains that science contends that the meaning of life is centered on the origin of life, both in terms of biological life and the universe itself. The paper then points out that, it is uncertain whether science can really tell us what is most significant in life in a philosophical sense. The paper also looks at how the meaning of life is said to be the question which was at the very heart of the classical moral philosophy initiated by Socrates. The writer believes that the only important thing is that you live your life in a way that you don't have regrets or you don't step on other people's feelings or rights.
From the Paper
"Another philosopher, Soren Kierkegaard, argued that life is full of absurdity and the individual must make his or her own values in an indifferent world. For Kierkegaard, an individual can have a meaningful life if the individual relates the self in an unconditional commitment to something finite, and devotes his or her life to the commitment despite the inherent vulnerability of doing so.
"These are but instances of how different people give different answers to the most-asked question about life. There are a million other contentions and concepts, may they be philosophical, religious or scientific in nature. These contentions and ideas depend on how one's beliefs are patterned or how one's experiences have shaped this belief system, or, maybe, his or her set of goals."
