Origin Of Solar System
Origin Of Solar System The Origin of the Solar System One of the most intriguing questions in astronomy today is the how our solar system formed. Not only does the answer add insight to other similarly forming systems, but also helps to satisfy our curiosity about the origin of our species. Although it is highly unlikely that astronomers will ever know with absolute scientific certainty how our system originated, they can construct similar theoretical models with the hopes gaining a better under...

The Brain
The Brain A.M.D.G 27th October 1996 The Brain By Manuel Socarr?s In the central nervous system of animals, the brain is a segregated group of nerve cells, or neurones, within the cranium, or skull, in vertebrates, and within the head segment in lower forms of animals. The brain varies in size and complexity from rudimentary ganglia (a group of nerve-cell bodies) in the central nervous systems of primitive worms to the large and complex human brain. As the central control organ of the body, the b...

In Support Of Human Cloning
In Support Of Human Cloning Human cloning is inevitable. As part of the progress of science, human cloning will take place regardless of who opposes it. In this paper I will explain what human cloning is, some of the ethical and moral objections to it, some medical benefits it could serve, what many different religions think of cloning humans, and ultimately why I feel that this would be beneficial to our society. In order to understand the objections and the potential of human cloning, one must...

Radio
Radio HISTORY Towards the end of the 19th century scientists were attempting to send messages over distances without wires. They were not searching for a means of mass-communication, but simply exploring the possibility of using electromagnetic waves in order to communicate between two fixed points. There in no single inventor of radio, it came from several international developments. The pioneers of radio studied the work of a British physicist James Clerk Maxwell, who published his theory of e...

Proposal For An Advanced Art Project
Proposal for An Advanced Art Project First off, I need to propose my theme that will encompass the majority of my art works in my stated media. Out of painting, print making and sculpture, I am choosing to work with the latter for two main reasons. One, I'm not that great at capturing visual ideas on the somewhat two-dimensional surface of paper or canvas. Adding to that I thought that sculpture would allow me to have a greater release of creativity as my work can explode into the third dimensio...

Fiber Optics
Fiber Optics Thesis: Some of the important features of the fiber optics that we are interested are discussed below. Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size. Fiber optics are used mainly to use effectively its high bandwidth. On a single fiber lots of information/data can be transm...

Photoelectric Effects
Photoelectric Effects Introduction The Quantum Theory was the second of two theories which drastically changed the way we look at our physical world today, the first being Einsteins Theory of Relativity. Although both theories revolutionized the world of physics, the Quantum Theory required a period of over three decades to develop, while the Special Theory of Relativity was created in a single year. The development of the Quantum Theory began in 1887 when a German physicist, Heinrich Hertz, wa...

Black Holes
Black Holes Black Holes There are many strange and wonderful phenomenons being discovered throughout our Universe. One of the most intriguing is the concept of a black hole in space. Astronomers have discovered a black hole just 1,600 light years away from Earth. The National Radio Astronomy Observatory cataloged this black hole in the constellation Sagittari on a star called V4641. A black hole is one form of a dead star. A star has three choices when it dies, it can: shrink until it is a white...

Radio: Making Waves In America
Radio: Making Waves In America Radio-wave technology is one of the most important technologies used by man. It has forever changed the United States and the world, and will continue to do so in the future. Radio has been a communications medium, a recreational device, and many other things to us. When British physicist James Clerk Maxwell published his theory of electromagnetic waves in 1873, he probably never could have envisioned the sorts of things that would come of such a principle. His the...

Image processing
Image processing 1.1 IMAGEAn image is an ancient rarity that portrays visual recognition, for example a two-dimensional picture that has a comparative appearance to some subject - for the most part a physical article or a man, consequently giving a delineation of it. An image is a cluster, or a network of square pixels (picture components) orchestrated in segments and lines. A picture is a two-dimensional capacity f(x, y), where x and y are the spatial (plane) organizes, and the adequacy of f a...

Ptolemy
Ptolemy Introduction In ancient times there were many great ideas which began to shape the way man perceived his environment. However, there were few minds who were able to put all of these ideas together. One of these minds belonged to Claudius Ptolemy, or just Ptolemy as he is commonly referred to. We know almost nothing of the chronology of Ptolemy's life, and we don't even know his birth or death dates. We do know, though, about his ideas in several fields, which include geography, astronom...

Nuclear Weapons, Explosive Devices, Designed To Release Nuclear Energy
Nuclear Weapons, explosive devices, designed to release nuclear energy on a large scale, used primarily in military applications. The first atomic bomb (or A-bomb), which was tested on July 16, 1945, at Alamogordo, New Mexico, represented a completely new type of artificial explosive. All explosives prior to that time derived their power from the rapid burning or decomposition of some chemical compound. Such chemical processes release only the energy of the outermost electrons in the atom. See ...

SUPERCONDUCTIVITY
SUPERCONDUCTIVITY The definition of superconductivity. Superconductivity is a phenomenon displayed by certain conductors that show no resistance to the flow of electric current. Conductors are materials in which the electron current goes through. There are 4 different kinds of conductors. Insulators, like glass or wood, have a very high resistance while semi-conductors, such as silicon, have a medium resistance. Conductors, like copper and other metals, have very low resistance, and superconduct...

Reflexology
Reflexology The origins of Reflexology evidently reach back to ancient Egypt as evidenced by inscriptions found in the physician's tomb at Saqqara in Egypt. The translation of the hieroglyphics are as follows: Don't hurt me. The practitioner's reply:- I shall act so you praise me. We cannot determine the exact relationship between the ancient art as practiced by the early Egyptians and Reflexology as we know it today. Different forms of working the feet to effect health have been used all over t...

History Of Physics
History Of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and ...

Human Body
Human Body In the Beginning Within a month of conception, the cluster of cells that will, in the course of time, become a human being begins throbbing, signaling the development of a primitive heart. Scarcely four weeks more pass before an intricate network of veins and arteries the size of a pea forms and subdivides into a tiny replica of the four chambers that will one day make up the adult heart. As the fetus grows, so does its vitally important circulatory system. Although most of the functi...

The Theory Of Evolution
The Theory of Evolution The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thoug...

Neutrinos And Gamma Rays
Neutrinos and Gamma Rays Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader's body. Neutrinos may account for an appreciable portion of ...

Polygraphs
Polygraphs Introduction Homo Sapiens have yearned for a reliable and consistently correct way of finding out if one is telling the truth since ancient times. ?Early societies used torture. Statements made by a person on the rack were considered especially believable.? (Jussim, pg.65) There was also trial by ordeal, which was based on superstition. For instance, if there were two suspects for one crime, it was thought that the innocent would be stronger in combat and thus vanquish a guilty oppone...

Catching Dreams
Catching Dreams Dreams are a window into the mind. These may be our most elaborate, distinctive, revealing, and flamboyant creations; they have fascinated us for thousands of years. The Egyptians built temples for dreaming. The oracles of Greece pondered cryptic dreams as the royal road to the unconscious. Dreams allow us to view beyond that which we are and know in daily life; they hint of other dimensions of space and time. What do dreams really mean? Are they mirrors of your days, tunnels i...

The Case For The Existence Of God
The Case For The Existence of God by Bert Thompson, Ph.D. Introduction Either God exists or He doesn't. There is no middle ground. Any attempt to remain neutral in relation to God's existence is automatically synonymous with unbelief. It is far from a moot question, for if God does exist, then nothing else really matters; if He does not exist, then nothing really matters at all. If He does exist, then there is an eternal heaven to be gained (Hebrews 11:16) and an eternal Hell to be avoided (Re...

Albert Einstein
Albert Einstein Albert Einstein was a famous scientist, writer and professor. He was born in Ulm, Germany, on March 24,1879. As a child, Einstein wasn't like the other boys: he hated school but loved math. He was shy, and talked very slowly. He didn't participate in sports but instead played with mechanical toys, put together jigsaw puzzles, built towers and studied nature. At school and home he would ask many questions and because of that everybody thought he was dumb. Once when he was sick in...
