... the mine. "Dust to Dust" by Charlie Angus explains this theory. There is a mining sickness that has taken many lives. It is called Silicosis. "In gold mines, the silica is found in the quartz veins that surround the ore. Disturbed dust attacks and lacerates the lining of the lung with it's jagged, crystalline edges. In the confined spaces underground, a miner has no choice but to breath in large amounts of silica dust. The effects of long term exposure are a litany of elements related to the breathing of this dust: silicosis, lung cancer, chronic obstructive lung disease, silica tuberculosis, pneumonia, asthma, br ...

... was, in essence, the speed of transportation. Perhaps no event so dramatizes this limitation as Pheidippides' run following the battle of Marathon in 490 BC. As told in the history books, a badly outnumbered Greek force defeated an invading Persian army on the plains of Marathon, 20 miles from Athens. Fearing that the defeated Persians would regroup and attack Athens and that the city would surrender without knowing of the victory, the Greek general dispatched his swiftest runner, Pheidippides. As he reached the city, Pheidippides stumbled, delivered his message, and fell dead of exhaustion. Paul Revere’s Ride "One if by land and two if by sea" refers to lantern ...

... Morse code messages. Shortly after World War II began bringing about the age of space exploration. After the war, the technology had been developed to send objects into space. Quickly, two nations acted to create a device that could relay radio waves from orbit. The U.S. made the first step. In 1954, the U.S. relayed a voice message off of the moon. Three years later, in the October of 1957, the Russians sent Sputnik 1 in orbit. Sputnik 1 sent radio beeps from space making the Russians the first to put an artificial satellite into orbit. The U.S. felt the increasing pressure of the need for space technology, and on July 29, 1958 the U.S. government signed the Na ...

... theologians like Aristotle and Nostradames. The Mayan calendar even speculates a worldwide event on this day. Very intriguing from a culture that supposedly predicted its own downfall. Christians refer to the book of Revelations for the foretelling of the Apocalypse and the seven seals, which tell how humanity will see its own destruction. Very detailed descriptions include famine, flooding, earthquakes, and celestial phenomenon. However, the turn of the millenium has many extremists worried that the world will end shortly and people are finding many “predictions” in everyday life. People have predicted enormous tidal waves, volcanoes, high winds ...

... and many different theorists. The purpose of this essay is to examine the trait approach, specifically the five-factor model. Both the development and limitations of the Five-Factor model of personality shall be discussed. Trait theory is based on several assumptions. The first assumption is that any difference between people that is seen as significant will have a name. Secondly, these names, known as traits, are conceived of as continuous dimensions. In general, trait theories assume that people vary simultaneously on a number of personality factors. These traits are of both the conjunctive and disjunctive form. Therefore, to understand a trait, it is neces ...

... speeding or dangerous driving. If you are at school you could forget all about learning and play games all day long. It does sound like a good life but would such a system work in reality? If you spend any time thinking about it then you must come to the conclusion that life would be more difficult without rules rather than easier. For example, imagine there were no rules regulating what side of the road you drive on, you decide for yourself when you wake up in the morning. Would you take a chance driving down a motorway in such a society when someone could be coming straight at you at 70 mph? How long would shops stay open if we were not obliged to pay for our goo ...

... Kowarski had escaped from the Institute Du Radium in Paris one step ahead of the invading german army. They took the world supply of 200 Kg of heavy water with them to Canada. Having pioneered the chain reaction using uranium and heavy water, the scientists applied their knowledge and their heavy water to the new Canadian nuclear industry. On September 5th, 1945 near Ottawa the team started up the first operating nuclear reactor outside the USA. Of course, the output was minuscule, but the significance was immense; the principal of getting energy from splitting atoms in a controlled chain reaction (fission) was established beyond doubt. It was now the j ...

... to be a business man, so he went and opened a store. This took a great deal of initiative due to the fact that many people dream of owning their own business, having freedom, and being sucsessful. But this is only a dream for many people because these people don't take the initiative or the risk it takes to own thier own business. Another example of this is , " Bill Gates." There are many different definitions to , "success," one may judge succsess on how much money make. This man in my mind is a, "geek." But a sucsessful one when it comes to money. With out his know how, and initiative he wouldn't be as sucsessful as he is today. He took the his idea of s ...

... problems; however, others overlook the greed and see validity in the financial aspect of today's sports world. They argue that professional sports are thriving and should not be modified. They also contend that sometimes lockouts are unavoidable and are often the only way to work out problems. The opposition reasons that professional teams with huge payrolls deserve all the money because they worked hard to get where they are. They argue that most players work hard to become great athletes and therefore they deserve enormous salaries. They also plead that lockouts are healthy for professional sports because they help each sport continually evolve and adapt to ...
