Air Pollution 2

... oxides, dust particles, radioactive isotopes, and chlorofluorocarbons. The major sources that enable carbon monoxide to enter the atmosphere are the exhausts of cars, the burning of fossil fuels, and the oxidation of natural methane. Carbon dioxide is caused by the consumption of fossil fuels only and it causes the possible greenhouse effect which has global warming as an outcome. Hydrocarbons are caused by the combustion of oil and petrol and it effects the environment with carcinogen. Carcinogen is a chemical agent that causes cancer. Su ...

Nuclear Fission

... of energy that is produced. The reaction occurs when a neutron strikes a heavy atomic element, such as uranium. The neutron splits the uranium atom. When the atom is split, it releases two more neutrons. These neutrons can then strike two more uranium atoms. The split of each atom will produce two more neutrons. The more atoms that are split the more neutrons produced that will split more atoms. As this process is repeated over, it becomes a self-sustaining chain reaction. This energy producing process is called a chain reaction. uses ...

Masters Of The Universe

... maximum density(Filkin 202). After all of the matter has collapsed in on itself, it becomes a black hole(Filkin 202). After being compressed infinitely, almost to nothing, the point in space that it makes is called a singularity(Filkin 216). The singularity is the bottom of the black hole. Every stellar body has an escape velocity(Intro. to Black Holes 1). The escape velocity is the speed at which one must be going to escape the gravity of the object in question(Intro. to Black Holes 1). The Earth’s escape velocity is seven mi ...

The Problem With Desertification

... only direct on-site loss. Indirect off-site and social costs of desertification damage may be two to three or even ten times as high (Atchia and Tropp, 1995). Desertification is the land degradation of productive drylands in arid, semiarid, and dry subhumid areas as a result of various factors, including climatic variations and human activities (World Atlas of Desertification, 1997) These drylands have been central in the evolution of mankind. These are the lands that sustained our transition from a hunting/gathering to pastoralism an ...

Glass

... in labware, bakeware, automotive headlights, and much more. Along with the many uses of , there are different properties, different es ans many interesting facts. The term is usually applied to silicate-based materials, non-crystalline solids. Basically a is any material that has congealed and become firm without forming a regular crystal formation.(Russ, 1998) The properties of vary and regulate by modifying the composition, production techniques or both. represents a combination of properties that can not be separated, such as mecha ...

Anti-Matter

... gravity as a push rather than a pull. If this were so, the antiproton's negative mass/energy would cancel the proton's when they met and nothing would remain; in reality, two extremely high-energy gamma photons are produced. Today's theories of the universe say that there is no such thing as a negative mass. The second and more subtle mistake is the idea that anti-water would only annihilate with ordinary water, and could safety be kept in (say) an iron container. This is not so: it is the subatomic par ...

Project Mercury

... applicants could be no more than five feet eleven inches tall, do to the limited amount of cabin space that the Mercury modules provided. All who met these requirements were also required to undergo numerous intense physical and psychological evaluations. Finally, out of a field of 500 people who met the experience, training, and height requirements, NASA selected seven to become U.S. astronauts. There names, Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil “ Gus” Grissom, and Donald K. “Deke” Slayto ...

Science And Ethics

... he created a life. But it wasn’t until the creature killed everyone Victor cared about when Victor started to realize what he had done was wrong. Victor realized that he never should have tried to play God. There is a fine line between scientific research and experiments that are morally, ethically, and religiously wrong and who are we to cross it? The first example of man performing corrupt experiments is genetic engineering. In this case, man alters the genes of the fetus. This might be acceptable if the reason for the alteration is a ...

Fiberoptics

... the first uses of fiber optics were mainly for illumination of signs and for toys. Recently though, technology has started to catch up and the uses of fiber optics are numerous. Fortunately for the high-tech society of today, some scientists and technicians researched the avenues of fiber optics. Fiber optics can be seen in telephone systems, in the military, in cars, in medicine, and in many other fields of study. For all industries and professions, "Fiber optics allow huge amounts of voice, data and video imagery to be transmitted insta ...

Nuclear Weapons

... Tactical nuclear weapons have the power of a fraction of a kiloton of TNT. Only two nuclear weapons have been used in warfare, each an atomic bomb dropped on Japanese targets by the United States in World War II. After the war, production of such weapons and the development of a more destructive bomb, the hydrogen bomb, caused worldwide concern. The atomic bomb was a bomb with great explosive force from the sudden release of nuclear energy through the fission, or splitting, of heavy atomic nuclei. The first atomic bomb w ...

Genetics

... also examine the effect of popular culture on our perceptions of cloning. Dolly’s case is not the first example of cloning. A man named Hans Spemann first envisioned cloning in 1938. He suggested transferring the nucleus of an embryo into another egg. As early as 1952, two scientists, Robert Briggs and T.J. King attempted what Spemann had suggested with a frog embryo and egg. Unfortunately, the frog egg did not develop. (Specter/Kolata) That same year, researchers in Pennsylvania cloned a live frog. The technique used was known as e ...

Mistakes People Make With Ster

... muscle size and strength, and help you train in less time. Today everyone seems to be looking for shortcuts to do just about everything. Performance enhancing drugs and supplements are just the thing for someone who is looking toward “bulking up” and increasing strength in a small amount of time. Steroids allow its users to recover more quickly from exercise than a natural athlete, so they can return to the gym sooner for another workout. So that means less work equals more muscle gain, compared to working out normally with no suppl ...
