.... weapon. From left to right: Neils Borh, Robert Oppenheimer, Richard Feyman, Enrico Fermi The object of the project was to produce a practical military weapon in the form of a bomb in which the energy would be released by a fast neutron chain reaction in one or more of the materials known to show nuclear fission. That goal was to be completed in 1945 after the U.S.A. spent over 6.7 Billion Dollars on the test bomb named the "Trinity". I t was dropped on Alagormado in Texas on July 16th 1945. When Albert Einstein heard about the "Trinity" he called the president directly and asked for a halt on all atomic bomb projects for he did not want to hurt an .....

.... it forms fat. Lipids have many uses amongst plants and animals. The main use of these are for energy and storing energy. When they store energy they make triglycerides also known as fat. There are also many other uses such as insulation and protection. They are also used in making cell membranes. They make it so that the cell can maintain it’s shape by keeping water and water-soluble compounds from passing through it. The lipids that are waxy are usually used to make protective coatings on the surface of plants and animals. Since a lipid is an organic compound it contains carbon. They also contain hydrogen and oxygen, but in some very com .....

.... serial killings, muggings, and smog. Times change. Many of today’s accepted virtues might one day be judged as crimes against humanity and nature, which leads to the question: What kind of world do you want to live in? Our ancient habit is to stumble backwards into the future. We feel that we as individuals make little difference, as if history and the future just happen at us. Obscure plans, which have guided people forward in the past, have now rendered themselves useless. There are no known maps to show pathways into the future. We’ll need to consider back to our hearts, common sense and basic human capabilities. We’ll nee .....

.... all four of the fuel pumps had failed. The worst possible news, they were out of fuel. In a few more minutes the engines stopped running, and all of the high tech instruments became useless. They realized that they could not even make it to Winnipeg. Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a race track, complete with race cars, fences, and spectators. The 767 crash landed, and, fortunately, no one was killed. Their were many contributing factors that made this plane run out of fuel. First of all, the computerized fuel gauge was not working, and a maintenance .....

.... by injection or the pill it increases strength and endurance. Steroids also help in the healing process of muscular tissue by first injuring them, then the muscles heal quicker adding more fiber increasing their bulk. Many athletes turn to steroids more often because they're cheaper then marijuana or cocaine. A ten week cycle of testosterone cypinate and methandrostone costs only about one hundred dollars. Steroids are also very hard to trace because of their water base composition. They can pass through the body within two days. All these benefits of steroids help an athletes become more competitive and increase their chance of .....

.... be to make sure to have a control group, to have a wide variety and different types of participants, to make sure all participants use the same equipment, and have controlled amounts of caffeine. The tasks for the participants would be to carefully follow the instructions of the experimenter, that is to hit the baseball. 3) Will you treat all the participants in the same way? No, I would not treat all the participants in the same way. The control group would not be given caffeine. However, I would treat all experimental groups the same because that will give more accurate results. If the participants were not treated the same I would not b .....

.... a low-self esteem and low levels of motivation (Morgan, 1997). The etiology of ADHD is still a mystery to researchers. Within the field there are many correlates to biological (genetic) and social causes. The present paper seeks to explore current research through investigating the social and bio-genetic influence of . Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, although not identical, will be considered interchangeably due to similarity. Characteristics and Testing of ADHD Intelligence Even though ADHD occurs in people of every intelligence, a majority of chi .....

.... with the outflowing solar wind, so that this feature should not have been considered a constraint on theories of the origin of the solar system. The many theories concerning the origin of the solar system that have been advanced during the last three centuries can be classified as either dualistic or monistic. A common feature of dualistic theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out filaments of gas from which the planets condensed. Theories of this type encounter enormous difficulties in trying to account for modern information about the solar system, and they have .....

.... are the uranium isotope U-235 and the plutonium isotope Pu-239 (Outlaw Labs). Fission occurs when a neutron, a subatomic particle with no electrical charge, strikes the nucleus of one of these isotopes and causes it to split apart. When the nucleus is split, a large amount of energy is produced, and more free neutrons are also released. These neutrons then in turn strike other atoms, which causes more energy to be released. If this process is repeated, a self-sustaining chain reaction will occur, and it is this chain reaction that causes the atomic bomb to have its destructive power (World Book, 1990). This chain reaction can be attained in two d .....

.... Earth's atmosphere, while other scientists believe that the health threat caused by global warming is due to an unusual interaction between cosmic rays and clouds as well as other natural occurring events. The National Weather Service announced that 1998 was the warmest year (on record on average, around the world). A recent tree-ring study indicated that this is the warmest decade in six hundred years (Allen & Herreid, 82). Undeniably, the weather is getting warmer. According to an article in The Economist, a conservative newsmagazine, "The sea is warming, the plankton dying; floods are sweeping the land. In California, the climate is acting .....
