History Of Physics Elise Early 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 a 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 of Miletus (636BC. - 546BC.) T
Star Wars tim ream People are always looking for a good way to escape the pangs of work. Since work is so important in society today that it is almost impossible to avoid doing work without having to pay the price in the future. The perfect escape would be one that alleviates the strain of work yet does not incur any future expenses. Many people have found science fiction novels and movies to be great escape mechanisms. Science fiction is such a perfect escape for many people because it allows i

Rave Culture: The Number One Example of Social Deviance Anonymous Introduction What is a rave? This is a fundamental question that, in a way, I will attempt to answer in this paper, but I will never do it. Raving is a highly subjective experience. One person's best rave is another person's worst. Any attempt to analyze rave culture must recognize the highly personal factor of the experience. It is because of this fact that I start off my attempt to analyze rave culture with a series of quotes on
The Eye and Laser Eye Surgery jess A Functioning Eye (Emmetropia) The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light. The perception of depth is due to having two separate eyes creating two separate images, while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two asp
Chemical reactions Unknown Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substa
The use of terror and fear are the primary weapons of the terrorist. Violence becomes the medium through which the terrorist spreads his fear. To the terrorist the threat of violent acts and atrocities become their means of communicating with the rest of the world. The spread of terrorism and the technological revolution in communication and transportation have run hand in hand. The introduction of jet aircraft in the 1950s and early 1960s gave the terrorist a degree of mobility and a field of o
Analyse information to identify the electromagnetic spectrum range utilised in modern communication technologies. The production and detection of electromagnetic waves at frequencies other than the visible range has produced a communications revolution. An image of the electromagnetic spectrum is shown on the right. The parts of the electromagnetic spectrum that we use for communication include radio waves, microwaves, infra-red, visible light and ultraviolet. Radio waves Radio waves have the lo
Technology An optical fibre ( or optical fibre) is a flexible, transparent fibre made of glass (silica) or plastic, slightly thicker than a human hair. It functions as a waveguide, or ˇ° light pipeˇ±, to transmit light between the two ends of the fibre. The field of applied science and engineering concerned with the design and application of optical fibers is known as fibre optics. Optical fibers are widely used in fibre-optic communications, which permits transmission over longer distances and
Batman and Superman Batman and Superman For over 75 years now, Batman and Superman have reigned supreme as the two most popular superheroes. Arguably, they are the two most popular superheroes of all-time. They are both characters of DC comics, and have inspired millions of children. Both of them have alter-egos, similar costumes, and a need for justice. Although Batman and Superman appear to be very similar, they are actually quite different in their origins, secret identities, and defensive ca
The Star Wars movies are probably one of if not the greatest movie franchise in history. It also happens to be one of my personal favorites since I own every single one of the movies. Most of them are still on VHS tape so you can tell that I have been a fan for most of my life. But unfortunately for myself and the countless other Star War fans there is a lot of “bad science” that occurs over the course of the seven film series. Let’s start with the lasers used throughout the films. First of all,
Changes to the Bill of Rights Anonymous How many rights do you have? You should check, because it might not be as many today as it was a few years ago, or even a few months ago. Some people I talk to are not concerned that police will execute a search warrant without knocking or that they set up roadblocks and stop and interrogate innocent citizens. They do not regard these as great infringements on their rights. But when you put current events together, there is information that may be surprisi
Why Software Systems Fail Pancham Bansal 1.0 Introduction In this report I will be concentrating on the failure of software systems. To understand why software systems fail we need to understand what are software systems. Software systems are a type of information system. This is because a software system is basically a means for hardware to process information. Flynn?s definition of an information system is: An information system provides procedures to record and make available information, co
Melbourne, Australia James Anderson Melbourne, one of the most beautiful city's in the world. I have traveled through the USA, Canada & the Bahamas, and still, I find Melbourne is the greatest. In 1981 I was born in a New South Wales mid-coast town of Port Macquarie. I lived there until I was the age of four, and that's when we made the move to Victoria. I grew up in Kew, a suburb of Melbourne, not far from the actual city. Most of my family lived there, and was the main cause for the move. I we
Cervical Cancer Statistical evidence about cancer of the cervix? The cervix is the lower part of the uterus (womb). The uterus is divided into two parts. The upper part or body of the uterus is where a fetus grows. The cervix connects the body of the uterus to the vagina (birth canal). The part of the cervix closest to the body of the uterus is called the endo-cervix. The part next to the vagina is the ecto-cervix. Cervical cancer is a type of cancer that begins in the lining of the cervix. Cerv

The land below us is always in motion. Plate tectonics studies these restless effects to give us a better understanding of the Earth and its past. New molten rocks are poured out in the form of magma from the mid-ocean ridges. The rock is recycled and re-entered back into the earth in deep ocean trenches through convection current. The convection current in the mantle drives plates around either against or away from each other. These collisions give rise to earthquakes, volcanoes, mountains, an

Nato Hits Chinese Embassy Doug Lee Three ultra-accurate laser-guided NATO missiles penetrated the walls of the Chinese Embassy in Yugoslavia from different angles, exploded in the core of the building and decimated it to wreckage. Three people were reported killed, and 21 injured, while one is missing. The Chinese government and people are terribly outraged at NATO's method of expressing its displeasures, calling it a barbarian act and that 'the U.S.-led NATO should bear all responsibilities.
Persian Gulf War-the Feat of the Western Countries Unknown On August 2nd, 1990 Iraqi military forces invaded and occupied the small Arab state of Kuwait. The order was given by Iraqi dictatorial president Saddam Hussein. His aim was apparently to take control Kuwait's oil reserves (despite its small size Kuwait is a huge oil producer; it has about 10 per cent of the world's oil reserves ). Iraq accused Kuwait, and also the United Arab Emirates, of breaking agreements that limit oil production in
Television (TV) is a telecommunication medium for transmitting and receiving moving images that can be monochromatic (shades of grey) or multicolored. Images are usually accompanied by sound. Television may also refer specifically to a television set, television programming, television transmission. The etymology of the word is derived from mixed Latin and Greek origin, meaning far sight: Greek tele (????), far, and Latin visio, sight (from video, vis- to see, or to view in the first person.
