... in August 1942, during World War II. It was made by a group scientist including the physicists Enrico Fermi and J. Robert Oppenheimer, and the chemist Harold Urey, and was in charge by an U.S. Army engineer, Major General Lesle Groves. After the war, the U.S. Atomic Energy Commission became in charge of all nuclear matters, including weapons research. Other types of bombs were developed to tap the energy of light elements, such as hydrogen. In these bombs the source of energy is the fusion process, in which nuclei of the isotopes of hydrogen combine to form a heavier helium nucleus. This weapons research has resulted in the production of bombs that range ...

... is hard to see this much money going to help just one whale. There are different types of animal stories that people hear about. There are the wonderful stories about adorable animals that do something amazing or need our help. There are also stories about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at risk of drowning because the holes in the ice that they were using to breathe were slowly freezing over. a large rescue was put together that ended up in ...

... 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of . Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite, or the soil which results from corroded granite. Acidic chemicals, and alkaline chemicals react to each other by reducing the alkalinity or acidicy of eac ...

... was primarily a tool of war and destruction when the war ended need for atomic bombs diminished. The scientists who created the weapons were out of jobs. They then turned this destructive power into huge plants generating"clean and cheap"electricity for the country. It was called progress. Progress also brought with it sickness, mutations, cancer and eventually death to those exposed to high levels of radiation. Government declared that nuclear power is safe and efficient. Also have big Oil corporations who have a lot of money invested in nuclear power and want to see as many plants as possible put into and kept in operation. The truth is that accidents do happe ...

... a way to ease them out of utilization. There are many reasons why the number of privately owned gasoline powered cars on the road should be limited. First of all, and most importantly, automobiles are harmful to our environment. Automobiles run on gasoline, which is a mixture derived from petroleum. Gasoline contains hundreds of different hydrocarbons, or compounds containing the chemical elements carbon and hydrogen(Gasoline). When the gas is burned in the engine of the car, several byproducts result. These exhausts include hydrocarbons and oxides of three elements: Carbon, nitrogen, and sulfur(Emissions). Tiny amounts of poisonous trace elements such as l ...

... I get one dumped in my lap. I had obtained an observation of P/Clark earlier, and needed to wait an hour or so before P/d'Arrest got high enough to look at, and was just passing the time til then, and I decided to look at some deep-sky objects in Sagittarius. When I turned to M70, I saw a fuzzy object in the same field, and almost immediately suspected a comet, since I had been looking at M70 last month, and *knew* there wasn't any other objects there." Thomas Bopp explains his story like this, "On the night of July 22, 1995 some friends and I headed out into the desert for a dark of the moon observing session. The site, which is west of Stanfield, AZ and a few ...

... thin strands, and they are tangled together into a network called chromatin. In addition to genes, chromosomes contain proteins, some of which cover the genes that are not "turned on" at the particular time. The original genetic information, stored in a coded form DNA, is carried out of the nucleus by RNA and then translated into proteins by ribosomes. 70% of oncogenes are located in the weak points of the chromosomes-hereditary regions where the DNA molecule may break or its portions may be rearranged into new combinations. Actually most of the times, the nucleus and the DNA are constantly exposed to substances that may alter the genes. But these alterations are ...

... his first paragraph, Nash writes of a world where humans can be cured of diseases that are currently life threatening. Where cells can be "cultivated in lab dishes" to help preserve human life. In the following paragraphs, he goes on to write about the "hasty legislation" that could possibly have negative long-term effects on the future of because of the bad wording going into some of the laws. Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nash points out that even though the possibility is there, the people who could grow full human clones "aren't going to be doing it." Nash recogniz ...

... It shares properties with both particles and waves. It follows the same rules as a wave does--it moves in a regular fashion, in a perfect sine wave at a certain frequency. It travels in a straight line, and is subject to refraction. All of these characteristics are found in waves of any type, from radio frequency waves, up to Gamma and X- rays. Light, however, also exhibits qualities characteristic of particles such as neutrons and protons. A photon, or quanta, is the "packet" of energy that is sent in a light wave. Like a particle, the photon is believed to have a finite mass, and has the ability to affect other matter. As light strikes a photovoltaic solar c ...

... prove to be fitting in order to manufacture pharmaceutical drugs. On the other hand, Dolly has also brought forth disgust and dismay. animals reflects a lack of respect for the individual animal's integrity and that the application of such technology will result in undesirable shifts in our view of how we may treat animals and how radically we can meddle with nature in general. Furthermore, it is stressed that, whatever potential uses it may be put to at some future stage, the technique raises a long string of ethical problems. In addition, it may be feared that within a number of years the development and application of animal techniques will lead to the t ...
