... because of their apparent vegetative state. Doctors who worked on the earlier cases believed the patients mental faculties to have been destroyed by the illness. Dr. Sayer (Dr. Oliver Sacks in real life) discovers that certain vegetative patients reacted to outside stimuli, such as a pattern on a floor, a tossed ball, or a television with a maladjusted vertical hold. Finally, Dr. Sayer comes across Leonard as a middle-aged man, some thirty years after he was originally afflicted with the disease. After doing some tests, the doctor comes to realize that there is brain activity and convinces his colleagues that further tests should be considered. He theorize ...

... by oil and gas combustion. is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce visibility by attenuating the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to reduce. Not only does it effect visibility, but it hastens the erosion of building materials and the corrosion of metals, interferes with the human respiratory system, and b ...

... Organizations, Source 4) The problems with fusion have been numerous. One of the problems is attaining the correct temperature for fusion to take place without using more energy then you produce. Fusion reactions occur at a sufficient rate only at very high temperatures. Over 100 million degrees Celsius is needed for the Deuterium-Tritium reaction, while other reactions require even higher temperatures. (Hotta Labs, Source 1) The density of fuel ions must be sufficiently large for fusion reactions to take place at the required rate. The fusion power generated is reduced if the fuel is diluted by impurity atoms released from surrounding material surfaces or ...

... after this fortunate discovery, scientists searched for another living coelacanth. Finally, off the Comero Islands, north of Madagascar, they met with success. Since then, more than 200 specimens have been found, all in the same region. Apart from the novelty of being such rare fish, have very great zoological importance. First, they are "living fossils"-a life form that has been preserved almost unchanged for many millions of years. As such, they offer the scientist a view of the biology of an earlier stage in the history of life. Second, the group of fishes to which the coelacanth belongs occupies an extremely important place in the vertebrate life. T ...

... downdraft. Not all precipitation-induced downdrafts are associated with critical wind shears. However, there are two types of down drafts that are particularly hazardous to flight operations because of there severity and small size. Professor T. Fulita, an atmospheric scientist from the University of Chicago, coined the term downburst for a concentrated, sever downdraft that induces an outward burst of damaging winds at the ground. He also introduced the term microburst for a downburst with horizontal dimensions of 4km or less (Lester 11-4). Microbursts form by the same process that produce the more common and less intense down drafts; that is, by precipitation ...

... from the soil, many methods have been developed in order to find ways to improve or change the soil to suit the plant's needs. Soil, in science as well as in common gardening, must undergo detailed inspection, to detect such things as the pH of the soil. A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill plants. Mineral content, as mentioned above, is also a concern, and must be clearly monitored. After inspection, it is common for minor organic materials outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold. It is after these steps that fertilization must occur, leading to a debate which has plagued ga ...

... do indeed have the power to duplicate an animal, plant and human body parts so that they are exactly identical to each other. For example, in May of 1998, scientists successfully cloned a calf using a new cloning technology that could make it possible to create "designer" cattle. Also, in June of 1998, there was talk about having successfully cloned a mouse swept through the scientific community(Nash 3). These are just a few of many times scientists have cloned an animal. These are the many things science has brought fourth and we need to take advantage of them. After studying both sides of the issue, I believe human cloning is a good thing to peruse for o ...

... to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were incorporated. This black powder was mystically identified with the underworld form of the god Osiris, and consequently was credited with magical properties. Thus there grew up in Egypt the belief that magical powers existed in fluxes and alloys. Probably such a belief existed throughout Europe in connection with ...

... slam into each other in a chaotic ceremonial dance. The purpose of the dance is to cause and endure as much physical pain as possible. The dance eventually gets so extreme that a young man in the crowd snaps his neck and dies. The man does not stop his ravings and the crowd doesn't stop their dance. Instead the man becomes entirely deranged, screaming at the body of the young man that he is now going to hell where he rot in flames of agony for eternity. The crowd roars and the man laughs. What do you suppose would now transpire? At the very least the man and the crowd would be arrested. More than likely there would be several charges of third degre ...
