......................................................... The year 2200, earth was at its finest dawn. People were now not in danger from war or disease, and the earth was at peace. A young boy of 15 years named Zadane who lived in one of Earth's largest cities was flying his hoversis (a type of remote control flying hover boat), in the Maltby flying fields. He suddenly saw the most beautiful colours of purple, reds, greens, and whites he had ever seen in his life come hurtling towards him.

Man-made satellites circle the Earth in many ways including polar and geostationary orbits. A satellite in a polar orbit travels over the North and South Poles. A polar orbit may be from several hundred miles to several thousand miles above Earth. This type of satellite circles the Earth approximately 14 times each day. Because the Earth is turning more slowly than the satellite, the satellite gets a slightly different view on every revolution. Over the course of a few days, a satellite in a polar orbit will cover almost all the planet.

In this essay it is shown that truth is found through, scientists, explorations, and philosophers. With these three topics we will be looking in depth at the works of Darwin, Christopher Columbus, Aristotle and Plato.
This is a fact of life and there is little doubt that this process did not play a significant role in changing the characteristics within a species. (This process is known as microevolution.) With his theory it is so simple and in accordance with every day to day observation of modern genetics that it has to be self-evident. With more evidence of his theory, fossil's have been uncovered that date back to early b.c. to prove his theory of evolution.

Original Writing Course-work - A concise history of the world, when considered in comparison with say, a good star trek episode seems pretty mundane.
"God made it...... In six days....... And then he had a rest". I fully concede to all Christians that the Bible is somewhat more detailed in its description of the event, but no more forthcoming with proof, than a collection of recently decapitated pheasants, in a bag. In fact it appears quite obvious, that the innonomate author, is making it up as he goes along. Either this or the archaic format with which genesis is written, holds little parallelism to that of modern day literary techniques and so appears simple and repetitive.

The first idea I will be looking at is that Star Wars is a type of fairy tale. This film contains many different examples to show that it has a link with fairy tales. The first is that the beginning sentence on the screen is 'In a galaxy far far away.' This shows a fairy tale beginning. There is both a villain who is Darth Vader with his Empire, and a hero who is Luke Skywalker, along with Hans Solo and Obi Wan Kenobi. There is usually a damsel in distress, who in this is case Princess Leia; she has been adapted as a modern princess, by being independent.

The 'space race' allowed both countries to challenge each other in a different way. Not to go to war fighting each other in space, but to use space exploration as a way of fighting each other through space, by trying to develop the knowledge to build inter-continental ballistic missiles. The first to do this would have a serious deterrent or threatening way of attacking. The 'space race' was also a way of showing off each other's scientific achievements and capabilities. However the Cold War has finished and the money given to space agencies has lowered.

How Solar panels and Solar cells are made and how they work? The solar cells that you see on calculators and satellites are photovoltaic cells or modules. Photovoltaic, as the word implies (photo is light, voltaic is electricity), convert sunlight directly into electricity. They could even power your house. The solar panel is the basic building block of the system. This is your battery charger. If you have several solar modules wired together you have created a solar array. The size of the solar array determines the amount of power or energy that will be produced.

* If the mass of the supergiant is great enough it can form what we call a black hole. * Since our sun is not a supergiant, but instead a medium yellow star, it will have a different fate. It will eventually use up its fuel in about 10 billion years, swell into a red giant, and then shrink down to a white dwarf. When it has completely cooled it will be a cold black dwarf. * Scientists feel our sun is already 4.5 billion years old and expect it to be around for another 5.5 billion years.

They started playing games and did not at work at all, for three days. If something like that happens millions of kilometres away from Earth, it would really be a problem. The whole mission could fail because the astronauts neglect the work they have to do. But not only stress, also isolation could become a real difficulty. The astronauts would be completely alone. They can not just go to a shop and buy something to drink. The different gravity on Mars could result in an increase in brain-size of the "colonists" - causing humanity to become "two-tiered" in terms of intelligence.

The devastating turn of events from environmental factors to scientific ones is whether major or minor surely affects "planet earth" unconditionally. Does it ring a bell through contamination, pollution and vast destructions?
The effects are large and one such effect, which is partly based upon, is ozone depletion and global warming. "Temperatures in the Arctic winter lower stratosphere are generally close to the threshold for substantial chlorine activation, making Arctic ozone particularly sensitive to small changes in temperature" " Annual ozone "hole" over Antarctica" "Do sunscreens matter?" KEVS THESE R JUST HEADLINES TAKEN FROM THE INTERNET SITE www.environment.about.com These controversial headlines which seemingly keep coming has sent the world into a frenzy of inexorable curiosity.

Helium can be obtained from natural gas wells where it has accumulated as a result of radioactive decay. Obtaining the noble gases Neon, argon, krypton and xenon are obtaining industrially during the fractional distillation of liquid air. There are only minute traces of helium in the air. Therefore, it is more economical to extract helium from the natural gas in oil wells. The physical properties of all these gases are monatomic. They boil at low temperatures as only dispersion forces act between the atoms.

With the loss of their ambassador, a lone ship crossed the border between these empires and bombarded a local planet in the Keldeen Empire. This was met with extreme anger from the Keldeen and the other races looked on in horror as the two races started a war with each other. All the other races tried to intervene for the common peace but were blown up by either side for "conspiracy against the commonwealth" and soon, the galaxy was plunged into an intergalactic war.

To the far south dark clouds were slow looming upwards, you could hear the wrath of the thunder in the distance. In the middle, at the edge of a small cliff facing the southwest sat a lone man. Like a statue, he sat there cross-legged, without movement, without a sound. His eyes were fixed on the necklace in his hand. He stared at it, watched the light shine of it, it was hitting him in his eye but that didn't really bother him.

This means that early earth must have been bombarded by comets, creating a highly hostile environment. This brings us to the first theory as to the origins of life on earth. As so many meteorites were colliding with the earth, it is not impossible to assume that several of these meteorites may have contained elements not found in abundance on earth at this time. Comets found in recent years have yielded many elements that were not thought to have existed in such abundance. So, could this have been the method of 'seeding life' onto the planet Earth?

The construct, of lasers, missiles and cannons jutting out of the gothic alcoves, is pushed on towards the planet. Ion engines are all that remain visible, as the battle ship strikes deep into the night. "This the Mars class cruiser Righteous Fire; we request permission to dock with the defence ring. We have an important visitor." A young officer adjusts his head set, his fingers dance over the runes, depressing and activating others. He turns to view a secondary monitor that crackles to life to show an ageing commander in full dress uniform, the green visual crackles with horizontal lines.

There are numerous forms of pollution that are causing considerable damage to our environment. Industrial factories release extremely dangerous chemicals in to the atmosphere, polluting the air, land and seas. Such chemicals contaminate water, which therefore affects the creatures and humans that use and rely upon it. Poisonous gases released pollute the air humans and animals breathe, which can affect the health of those who need it. This build up of harmful gases, such as CFC gas, in the atmosphere undoubtedly has serious long-term affects on the planet Earth. Growing problems, like the 'greenhouse affect' and the hole in the ozone layer, are the consequences of the actions of humans.

2. Aims and Objectives This project is made to understand the functions of the GEO satellite. It is important to recognize these satellites, as satellites are important in our daily lives such as networking and communication. I also learn to know the usage of these satellites. I also know how to differentiate the advantages and disadvantages of the GEO satellite. 3. Historical Background (Geostationary, LEO, MEO, HEO Orbits 4/7/2002) YEAR EVENTS 1945 * The orbit, which geosynchronous satellites must describe around the Earth, was first suggested by science fiction writer Sir Arthur C. Clarke. He suggested in an article in "Wireless World", published in 1945, that it would be possible to have global communications with only three strategically located GEO satellites.

The further out you go, the weaker it pulls. The orbits of the planets are elliptical (elongated) rather than circular. This means that their distance from the Sun is continually changing. The average distance from the Sun to Pluto is much greater than the average distance to Neptune but because of the highly elliptical orbit of Pluto, there are times when Pluto is closer to the Sun than Neptune. The further the planet is from the Sun, the greater the time it takes to orbit it. The distance from the earth to the other planets depends on where they are in their orbits.

While in Italy, among other things he studied the accepted astronomical system of the time, developed by Ptolemy. This system depicted the universe as consisting of the earth and ten spheres: the moon, Mercury, Venus, the sun, Mars, Jupiter, Saturn, the Firmament (fixed stars), the Crystalline Heaven which imparted motion to the spheres around the earth, and finally the motionless Empyrean Heaven where God dwelt with the elect. These spheres were generally believed to be solid and transparent, and the planets to be of a non-earthly weightless substance fitted into the spheres and revolving with them around the motionless earth.

This is also another income, which is received, even though it isn't as obvious. Unlike many of the other cinemas, there is a wide range of people who visit the complex. Youths and adults and teenagers visit the complex. The reason for this is because, there is a lot to do for all of the different age ranges. People can do as they please, and use the services available. There is more then a cinema, so, people also visit the complex for other reasons, besides to watch films.

Recyclable materials: Paper is also included into this group but other non-biodegradable items such as plastic, glass and metals fall into this. 3. Inert waste: These are materials that are not necessarily harmful to all species but they are harmful to humans. For example, construction and demolition waste. 4. Composite waste: This includes items composed of more than one material such as clothing and plastics such as children?s toys. 5. Household hazardous waste: This includes medicine, paint, batteries, pesticide and e-waste. Household hazardous waste cannot be disposed or recycled so many cities offer other options for disposing these items.

This means we can never fully observe the life of a star; from its birth to life to death. Our Sun is a perfect example of a star, and there is an incredible amount of stars in the Universe. It is a star among hundreds of billions of stars that is featured in our Milky Way Galaxy and our galaxy is one of billions of galaxies in the universe. In determining the life cycle of a star, astronomers observe many of the billions of stars around us and see them at different stages of life, therefore putting together a star's evolution.

The cloud starts to clump together due to gravity. The cloud gathers together over thousands of years and spins slowly. The fast rotational force causes heat energy to form and increase the energy of the whole structure. As the heat increase and the rotational force increase that cloud becomes more and more compacted. This keeps increasing the speed and heat energy and gravity. Eventually the cloud of dust and gas compacts so much that is forms a vague circular shape. This is called a protostar. As a protostar it is incredibly hot and busting with energy.
