.... formed star is immediately surrounded by a relatively dense cloud of gas and dust. In 1965, A. Poveda stated, “That new stars are likely to be obscured by this envelope of gas and dust (1).” In 1967, Davidson and Harwit agreed with Poveda and then termed this occurrence, the “ cocoon nebula” (1). Other authors have referred to this occurrence as, a “ placental nebula” (1), noting that it sustains the growth of planetary bodies. For a long time, even before there was the term cocoon nebula, planetary scientists knew that a cocoon nebula had surrounded the sun, long ago, in order for our solar system to form and take on their currents motions (1). In 1 ....

.... Apollo for its apparition as a morning star, and Hermes as an evening star. Greek astronomers knew, however, that the two names referred to the same body. Since Mercury is a smaller planet, extremely close to the sun, and has no substantial atmosphere, it has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin. On the side facing away from the Sun, or the night side, the temperature drops to -183 degrees Celsius. Scientists have detected a magnetic field surrounding Mercury, though it is not as strong as th ....

.... and its belief in survival of the fittest to all areas of life. They used it as a “natural law” which supported their actions and beliefs. Advocates manipulated the scientific doctrine to fulfill their personal needs and to justify religious beliefs, capitalism, and military conquests. Darwinism greatly impacted the scientific world purely through its specific doctrine. The enlightenment had paved the way for rational thinking and observation. People were willing to accept scientific data as fact and they were able to objectively consider theories that went against the church. Because of the story of creation, Darwinism would have been immediately rejected only ....

.... Roslin Institute, led by embryologist Lan Wilmut, reported that they cloned a sheep-named Dolly-from the cell of an adult ewe. The next goal of scientists is to sequence all human DNA by 2003, the Human Genome Projects current target date (Lemonick 46). But we should use genetic engineering in a proper way. Our goal should be to find areas where it is needed rather than try to misuse it for personal gain. Genetic engineering can provide medical benefits to humans, but limits have to be set. Our body contains one hundred trillion cells, inside most cells is a nucleus that contains a complete set of the body’s blueprints. Those blueprints are twisted into forty-six ....

.... cancer (melanoma) in humans. As UV-B rays increase, the possibility of interferences with the normal life cycles of animals and plants would become more of a reality, with the eventual possibility of death. Stratospheric ozone has been used for several decades as a tracer for stratospheric circulation. Initial measurements were made by ozonesondes attached to high altitude balloons, by chemical-sondes or optical devices, which measured ozone concentrations through the depletion of UV light. However, the need to measure ozone concentrations from the surface at regular intervals, led to the development of the Dobson spectrophotometer in the 1960s. The British Antarctic Su ....

.... and improve flexibility, are sometimes fortified with short-fiber additives, mostly fiberglass. This is known as a polymer composite. One particular polymer has three times the strength of tempered steel and is being used in bullet proof vests. Another composite will be used to fasten together the sections proposed space stations. have also been used in cars, including the Chevrolet Camaro and the Pontiac Fiero. New are being created with more strength and flexibility by combing two chemically different and producing a block copolymer. Combinations of block co and composites and intended for use in booster rockets and in materials of Earth-orbiting installatio ....

.... travel industries in this world and they all contribute to the chemical pollution, weather it is cruise ships, hotels near the water, or boat tours. Fishermen also pose a threat to our oceans by over fishing our waters. The way they are going there will not be enough fish for a maximum sustainable yield, and our fish population will die. Fishermen also clean there fish and throw the guts overboard into the ocean. Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of those products I just named regularly end up in water. About 65,000 chemicals are used commercially in the U.S. T ....

.... elements. The element is named after Alfred Bernhard Nobel, the Swedish inventor and philanthropist. Nobelium can be found when produced artificially in a laboratory. Discovery of the element was first claimed in 1957 by scientific groups in the United States, Great Britain, and Sweden, but the first confirmed discovery of a nobelium isotope was by a team of scientists at the Lawrence Radiation Laboratory in Berkeley, California and that took place in 1958. The isotope was created by bombarding curium isotopes with carbon ions. Chemically, the properties of nobelium are unknown, but because it is an actinide, its properties should resemble those of the rare earth ele ....
