.... the inability of the individual talk to the other end of a radio transmission chain. When one switches stations on our radio, there is no interaction, we are simply selecting from a series of predefined options, just like changing channels on television. If you switch from one station to another, none of the stations know about it, and can do nothing to make their programming more interesting than their competition. The Internet has no such limitations, from the ground up; it was designed as a mass communications medium that was two ways. With the Internet, there is no broadcaster or receiver and you can easily talk back to the c .....

.... This fact alone makes him one of the most important people of science ever. Charles Darwin was born in Shrewsbury-Shropshire, England on Feb 12, 1809 (GEA & RBi p 42). He was the fifth child in a wealthy English family with a history of scientific achievement with his paternal grandfather Erasmus Darwin who was a physician and a savant in the eighteenth century (GEA & RBi p 42). As a young boy Darwin already showed signs of his love for nature. When he was not reading about nature and its quirks he was out in the forest looking for wild game , fish, and insects (Campbell p 424). His father, although noting his son's inte .....

.... They land on Mars, and do their business. When they’re done, the habitat lander takes them back up to orbit where they meet back up with their CTV, waiting patiently in orbit, that takes them back home. The money issue is being handled in many different ways. The most successful plan so-far is the ThinkMars plan. Students at MIT and Harvard are setting up a for-profit corporation which they contract out various tasks to small businesses and corporations for NASA research centers. The US and other govt.’s help out by buying certain rights to the space craft, while the corporation will sell certain media rights and other .....

.... the most abundant due to the fact that the abundance of the other elements of the crust are too low to graph accurately on one graph. Almost all elements are found as compounds, however Oxygen, Nitrogen, and to a lesser extent sulfur, gold, silver and platinum are the only elements which can be found in almost there raw sate. The atmosphere contains Oxygen and nitrogen, but it only contains a small portion of the earth's oxygen, this is because most of the world's oxygen is found in water, oxides of metals, and as silicates. Common soils and clays are silicates. 2. Living Things In living things (plants, animals, people) .....

.... Rubidium are found in the leaves of tobacco, tea, and coffee, as well as some other plants. Rubidium is similar to lithium and cesium, which are found in combined forms as complex minerals. It is not found in a pure elemental (metallic) state in nature, but only as compounds in mineral deposits such as pollucite, carnallite, lepidolite, leucite, and zinnwaldite, in addition to mineral springs. These various minerals are found in the United States in California, South Dakota, New Mexico, and Maine. There are 17 known Isotopes of Rubidium. The only 2 naturally-occurring isotopes are Rb85 and Rb87. Rubidium-87 is present to the .....

.... fact they are often a consequence of relative immobility. These findings underscore the enormous importance of exercise in the fight against arthritis. You should realize that immobility will set off the destructive set of events. After four or five months, such degeneration may be quite well along, so that even if you initiate a program of vigorous exercise, you may have to wait up to a year for the joint's normal motion to return. Therefore, I say, prevention is the order of the day. Exercise exerts very favorable influence on the immunological system, affecting the production of white blood cells, lymphocytes and leukocytes, as .....

.... the most noticeable of these problems. The hazy smog that hangs over us in the summer is actually ground level ozone; the most harmful pollutant of our air (Information 59). Pollutants of the air we breathe are very dangerous and cause many problems especially to people with breathing disorders. For instance, the E.P.A. estimates that emissions of toxic material like these “oxides” cause some 2000 cancer deaths a year (Information 61). The rainwater that falls through this polluted air also poses a major risk. Industrial plants and automobiles emit chemicals that mix with the moisture in the atmosphere and form a .....

.... very slowly at around 880 degrees Celsius. The metal combines with oxygen at red heat, and with chorine at 550 degrees Celsius. when a metal, is considered to be physiologically inert. Pure dioxide is kind of clear and has an extremely high index of refraction with an optical dispersion higher then diamond. The location of on the Periodic Chart is in the series of sub groups called transition elements. Other then the fact that transition elements are metals, there is not a single property that all transition metals have in common. Some of the prier and current uses for are as follows: It is used in many types of alloys as a s .....

.... with AIDS. However since 1989, heterosexual sex was found to be the fastest growing means of transmission of the virus, with 90 percent of the new cases coming from heterosexual sex. How AIDS Is Spread AIDS is transmitted by direct contact of the bloodstream with body fluids that contains the AIDS virus, particularly blood and semen from an HIV-infected person. The virus is usually transmitted through various forms of sexual intercourse, the transfusion of virus-contaminated blood, or sharing in HIV-contaminated intravenous needles. The AIDS virus cannot enter intact bodily surfaces, such as skin, and quickly .....

.... origins. A very highly debated topic within the bigger argument is, “What started it all?” Creationists believe that God merely spoke all that we know into existence, but evolutionists prefer to believe a massive, random explosion spawned the cosmos. Obviously, a middle-grounder could find both preposterous. The very first line of the Holy Bible states, “In the beginning, God created the heavens and the earth.” For such a massive, random occurrence on the evolution side is quite hard for one to fathom, but for a massive, controlled occurrence to take place would be quite another thing all together. So, it would be very .....
