... and plants. Every trait has one or more gene associated with it. Thus, natural selection provides the animals and plants with the best genes. Supporters of neo-Darwinism believe that natural selection operating upon random variation gave rise rise to all animals and plants. While the source of variation is random, the direction of evolution is not. In effect, natural selection removes chance, and it makes the theory of evolution plausible. If neo-Darwinism is correct then numerous small successive changes guided by natural selection gave rise to all animals and plants. I will prove that natural selection is not a creative process. Its prim ...

... the surface, they both appear meaningless and bizarre, but they become understandable when understood as veiled expressions of an unconscious clash between competing motives. Freud developed an elaborate theory and how the mind works while asleep. In 1953 sleep researchers led by Nathaniel Kleitman made the important discovery of rapid eye movement--or REM-- sleep. Curious about the long-standing observation that the eyeballs of sleeping subjects in both humans and animals periodically move during sleep, they connected laboratory subjects to equipment that measured their brain waves, muscle tone, and eye movement. About 90% of the time when subjects were awakened ...

... and calculations are more accurate than manual calculations. These machines are enabling us to perform many different tasks in less time and making our lives easier. Computers in telecommunications have allowed us to do many things from the comfort of our homes that could never be done before; such as talking with distant friends and relatives, buying merchandise, doing research, and a steadily increasing number of other things. At nearly any time of day we can buy something with a credit card, or fill out a form with personal information such as a loan application, job application or insurance form. Years ago, sending this amount of personal data was ...

... uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the late 50's, however, LSD was used by the CIA as an interrogation drug for spies. However, it was proven to be unreliable and was later replaced with other interrogation drugs. LSD comes in the forms of crystals, liquids, tablets, gelatins, or blotting squares. The squares have designs on them such a flowers, dragons, shapes, animals, and cartoon characters to make them more attractive to young children. Often called acid, ...

... I had recently read about the dangers of scientific some advancements. Coincidentally, the article was called, “Brave New Worlds”. It stated that “Developments in the field of genetics offer the possibility of bringing all life processes under control. We must step carefully into this vast new field of science with the understanding that putting a patent on the melanoma gene or the baldness gene for that matter is simply playing God in a potentially dangerous way.” (Appleyard, Bryan, Jan 98, Smithsonian) These are only a few examples of scientific developments that in my mind raise the question: in science? Mr. Appleyard could not have been more on point in his al ...

... the need for other drugs. Steroids though take a few hours to have an effect and therefore ineffective if needed for immediate relief. Other treatments include allergy shots and Antihistamines which can be used as a preventer of asthma. These reduce allergic reactions in patients and therefore reducing the chance for allergies to trigger inflammation in the asthmatic. Antihistamines however, cause drowsiness and should not be taken when driving or working at jobs where you must be alert. The medications that are discussed in the case study are bronchodilator inhalers (such as ventolin) and Cromolyn (Appendix 1). Bronchodilators are asthma relievers and there ...

... suggest that leptons and quarks may actually be the same object but in different states. Bosons, too, may be this same object but in still another state. The everyday world is made of molecules. Because molecules are so small, their existence was not easy to establish. Indirect evidence for molecules was strong during the second half of the 19th century, and the first explicit evidence was found when Brownian motion was correctly understood and studied in about 1906 by physicists Albert Einstein and Jean-Baptiste Perrin. There are many kinds of molecules, and it was clear that simplifying ideas were needed. The Russian chemist Dmitri Mendeleev argued that there ...

... into the learning process and his idealist view of having a planned society. He was born in Susquehanna, Pennsylvania in 1904. He graduated from Hamilton College in 1926. After becoming interested in the works and studies of John B. Watson and Ivan P. Pavlov, he studied with animal learning and functions of the nervous system. He received his Ph.D. in behavioral psychology at Harvard in 1931. In 1936, he then worked as part of the faculty at the University of Minnesota. A few years later in 1939 to 1945, during World War II, he designed the "baby box" or better known to psychologist as the "Skinner box". It was a controlled environmental chamber for infants and he w ...
