  • Geology 170 Report: - 986 words
    GEOLOGY 170 REPORT: MT. ST. HELENS: Mount St. Helens is located in southwestern Washington about 50 miles northeast of Portland, Oregon. Mount St. Helen is one of several volcanic peaks that dominate the Cascade Range in the Pacific Northwest. The principal part of the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. It was considered one of most beautiful mountains in the Cascade Mountain Range. St. Helens was often compared to Mount Fuji in Japan because of the mountain's similarity in appearance. All of that would change on May 18, 1980 when the young and quiet Mt. St. Helens decided to become an active volcano and cause the worst natu ...

  • Acid - 1,218 words
    Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases. Many people believe that this issue is too small to deal with right now, and others believe it should be met head on. In the following paragraphs I will be discussing the impact of acid rain effects on wildlife and how our atmosphere is being destroyed. Causes Acid rain is a cancer, eating into the face of Eastern Canada and the North Eastern United States. In Canada, the main sulphuric acid sources are non-ferrous smelters and power generation. On both sides of the border, automobiles are the main sources for nitric acid (about 40% of the total). Power generating plants, industrial com ...

  • Acid Precipitation - 663 words
    Acid Precipitation Acid Precipitation Our atmosphere functions as living ecosystem of chemical reactions. Through the help of the water cycle, chemicals pass through the atmosphere and are eventually taken up by the soil, surface water, or organic materials. Human beings have added enormously to the atmospheric burden of many toxic substances. The most prominent evidence of this is the presence of acid rain: precipitation and particles that have been made acidic by air pollution. Acid rain is a direct consequence of the atmosphere's self-cleansing process. The tiny droplets of water that make up clouds continuously capture suspended particles and soluble trace gases. Not all trace gases can ...

Munn Community College of Philadelphia Recently, the media has spent an increasing amount of broadcast time on new technology. The focus of high-tech media has been aimed at the flurry of advances concerning artificial intelligence (AI). What is artificial intelligence and what is the media talking about? Are these technologies beneficial to our society or mere novelties among business and marketing professionals? Medical facilities, police departments, and manufacturing plants have all been changed by AI but how? These questions and many others are the concern of the general public brought about ...

It has yet to impress the people that really count: financial officers, corporate treasurers, etc. It is quite understandable though, who is willing to sink money into a system that they cannot understand? Until a track record is set for chaos most will be unwilling to try, but to get the track record someone has to try it, it's what is known as the catch-22. The chaos theory can be useful in other places as well. Kazuyuki Aihara, an engineering professor at Tokyo's Denki University, claims that chaos engineering can be applied to analyzing heart patients. The pattern of beating hearth changes slightly and each person ...

Franklin's scientific and analytical mind enabled him to generate many long lasting achievements which contributed to the development and refinement of modern technology. Few national heroes, including George Washington and Thomas Jefferson, played a more significant role in shaping the American way of life than Franklin. According to Fowler, He personified the ideal of the self-made man, and his rise from obscurity to eminence exem ...

  • Charles Darwin - 1,851 words
    Charles Darwin Charles Robert Darwin was a man of many hats. He was a friend, colleague, son, father, husband; but above all, he was a naturalist. Through his dedication and perseverance did he manage to, in less than a generation, establish the theory of evolution as a fact in peoples' minds. In fact, [t]oday it is almost impossible for us to return, even momentarily, to the pre-Darwinian atmosphere and attitude (West 323). Darwin formed the basis of his theory during the voyage of the H.M.S. Beagle, on which vessel he was posted as it travelled around the globe. During that five-year span, this young man saw foliage, creatures, cultures that he had never known first-hand before. He was exp ...

  • Charles Darwin - 372 words
    Charles Darwin Darwin was born in Shrewsbury, Shropshire. He was the son of Robert Waring Darwin and his wife Susannah; and the grandson of the scientist Erasmus Darwin, and of the potter Josiah Wedgwood. His mother died when he was eight years old, and he was brought up by his sister. He was taught classics at Shrewsbury, then sent to Edinburgh to study medicine, which he hated, and a final attempt at educating him was made by sending him to Christ's College, Cambridge, to study theology (1827). During that period he loved to collect plants, insects, and geological specimens, guided by his cousin William Darwin Fox, an entomologist. His scientific inclinations were encouraged by his botany ...

  • Charles Darwin 18091882 - 423 words
    Charles Darwin (1809-1882) From a young age Charles Darwin disliked school and instead he liked observing birds and collecting insects to study. When he was 16 years old, Darwin was sent to a medical school in Scotland, which he found as a waste of time. In 1827, Darwin enrolled in the University of Cambridge, England. He also though that his time was wasted there too, as far as academic studies were concerned. Henslow, a professor of botany in Cambridge and Darwins friend, encouraged Darwin in his studies of natural history. In 1831 Henslow recommended that Darwin be chosen for the position of naturalist on the ship the HMS Beagle. For Darwin, the Beagle was chartered for a five-year mappin ...

  • Darwinism - 214 words
    Darwinism Darwin doesn't work here any more Richard Milton spent some twenty years studying the geology and palaeontology of the British Isles before writing Shattering the Myths of Darwinism. It was the absence of transitional fossilsthat first made me question Darwin's idea of gradual change. I realised, too, that the procedures used to date rocks were circular.Rocks are used to date fossils: fossils are used to date rocks. From here I began to think the unthinkable: could Darwinism be scientifically flawed? I became an almost daily visitor at the Natural History Museum, looking more closely again at all the famous evidence I had been taught about:the evolution of horses, Archaeopteryx -- ...

  • Dinosaurs Extinction - 1,537 words
    Dinosaurs Extinction The first question that must be posed when trying to crack the mystery of the mass extinction is to ask, throughout history were there any other occurences of this magnitude? The answer is a resounding yes. Altogether over time there has been about eight mass extinctions to large land dwelling vertebrates. The most recent was about ten thousand years ago, killing most of the giant mammals like mammoths, mastodons, super-large camels, saber-toothed tigers, and others (Bakker 428). The second question, is whether or not these mass extinctions follow a pattern? Once again the answer is yes. Every time a mass extinction occurs on the land ecosystem, the oceanic system is hur ...

  • Environmental Effects Of Global Warming - 1,713 words
    Environmental Effects Of Global Warming Environmental Effects of Global Warming The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earth's atmosphere starts to warm, which leads to global warm ...

  • Evolution - 353 words
    Evolution The process by which all living things have developed from primitive life forms through changes occurring over billions of years is evolution. All living things arose through a long history of changes formed by physical and chemical processes that are still taking place. It is possible that all organisms can be traced back to the origin of life from inanimate matter. Paleontology is the most direct proof of evolution because it studies life of the past. Approximately 2 million different species of organisms are now living, but at least 99.9 percent of the species that have ever lived are now in extinction and about 2 billion species have evolved during the past 600 billion years (B ...

  • Exploring Mars - 1,479 words
    Exploring Mars MARS SURFACE EXPLORATION One question that is being asked by people is, "Why go to Mars"? The reasons are very simple. People want to gain recognition of how they were the first people who went to Mars and opened up a whole new world and most importantly to move forward in economics. As humans waste the precious materials and resources found on this planet we have to consider going to other planets to explore for materials and energy resources. Mars would be the first area for industrial development and mining in the "new world". There are talks that by the end of this century that a manned mission to Mars should take place. We must start preparing ourselves properly in order ...

A professional astronaut would have the skills to easily spot a protected site that would be favourable to life. An example of this would be a spot sheltered by a rock. Equipment which is automatic that astronauts have is better for things like, repetitive measurements which would be stretched over long periods of time. Scientific research will be divided into two main categories. There would be a day to day exploration by the astronauts which would have more difficult tasks. They would also be resp ...

In accordance with Albert Einstein's relativity theories a speed of light traveling starship would require an infinite amount of energy. Even a ship travelling at 99.99% the speed of light, 186,000 miles per second, would require just as large an amount of energy, almost infinite. Regardless of these scientific restrictions to space travel of enormous distances some evidence suggest the occurrence of out of this world experiences that cannot be explained. Alien abductions as well as U.F.O sightings are among the most known evidence of human contact with extraterrestrials. Although most abduction stories or UFO stories are pro ...
