Three Minutes Half Life
528 wordsThere are 109 known elements, and of those, 19 of them are artificially produced or synthetic. A synthetic element is made by bombarding atomic nuclei with neutrons or other particles. The element Lawrencium has been made in this manner. While scientists continue to work to create more elements, it should be noted that most synthetic elements are so unstable, that they are of theoretical value only, and have no known practical uses. This element was discovered at the Lawrence Radiation Laborator...

Using Irradiation To Make Food Safer For Consumers
1,171 wordsUsing Irradiation to Make Food Safer for Consumers In the world today, there is a limited access to fresh and uncontaminated food. Gunjan Sign, of Popular Science, reports that "The U. S. Centers of Disease Control estimates 6. 5 million confirmed cases and more than 25 million additional unreported incidents of food poisoning each year" (65). For example, with seventy-five percent of the chicken in Europe and sixty percent of the chicken in the United States infected, salmonella is a serious pr...

Chemical Reaction Living Things
502 wordsWhy is knowledge of chemistry important to biology? Biology is the study of all living things and chemistry is the study of chemicals and their interactions. So, how are they related? Our bodies are made up of hundreds and hundreds of chemicals. We just dont think of them like that. Did you ever wonder how your body turns food into energy? Its a chemical reaction. Thats chemistry involved in biology. Our bodies have hundreds more chemical reactions. A chemical reaction is one chemicals response ...

Valence Electrons Carbon Dioxide
328 wordsFor my report, I choose to design a ball and stick model for a carbon dioxide molecule. I used the C as the center and an O on each side of the C. For Christmas purposes I colored the C green and the two Os red. To make the letters, I used white out. The sticks that connect the balls are actually cue tips that I have taken the cotton off of. I used glue to make it stick on better and just punched in the stick. The sticks are suppose to be springs and I tried bendable straws that were cut, but th...

Speed Of Light Theory Of Relativity
1,257 wordsAlfred Einstein was born in Ulm, Germany on March 14, 1879. You might ask yourself, what would it be like to be born a genius? If you were anything like Albert Einstein you were a very quiet, secretive child who had trouble in school and against authority. And most of all, you would not be a child prodigy as some people might think. Some believed Albert Einstein was "backward" (Current Biography, 257) when he was young, because he could not speak fluently when he was nine. But even as young as f...

Nuclear Power Plants Advantages And Disadvantages
593 wordsNuclear Power has its advantages and disadvantages. However it is a lot safer than most people think. The chances of a meltdown or a radiation leak are extremely small. There are many safety features, which make nuclear power one of the safest electricity sources. And every nuclear power plant is protected with thick layers of steel and concrete. Nuclear power is also very environmentally friendly. It produces hardly any air pollution, and it releases less radiation into the atmosphere than coal...

Valence Electrons Periodic Table
854 wordsThe periodic table is simply the organization and classification of different elements. By the end of the 1700 s, scientists had identified about 30 elements. In less than 100 years, the number of known element doubled because of new means of recognizing them. In the early 1800 s, Dobereiner observed that there were elements that could be classified into groups of 3, or triads. These triads were significant because these classifications of similar elements represented the very beginning of the p...

Eternal Life Person Dies
1,046 wordsAssignment # 2 France Home Student # 0171717 April 4, 2005 Dr. David Humbert RLST 2326 EL "Are we alone in the universe?" Scientists have been trying to answer this question for many years. As of now there has not been any rock solid evidence to prove that there is life outside this world, but there is an overwhelming amount of people that believe that there is life. People only believe that there is life outside earth, they don't know there is. It is hard to know that extra terrestrials exist u...

Impact On Society Reproductive Cloning
1,436 wordsInfinite Possibilities If Mirrors Face The inevitability of human cloning is unavoidable. Although a majority of individuals disapprove the idea of cloning humans, I firmly believe that, not only will human cloning be widely practiced in the near future, but it will also benefit the health and well-being of all humanity. Just visualize for a second that you are one of the human clones that will exist within this decade, and imagine putting up with all the arguments that many opinion leaders are ...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...

Earths Magnetic Magnetic Field
1,384 wordsINTRODUCTION: The magnetic south and north poles of the earth create magnetic field lines in which these bacteria travel. These bacteria were found to contain iron, which is comparable to ferromagnet's or magnetite produced synthetically. This iron is found to line up to the magnetic field lines similar to how a compass works. Many of the principles of magnetism can be explained by observing these bacteria. NARRATIVE: The physical principles behind magnetic bacteria rely on the earths magnetic f...

Nuclear Power Plants Coal And Oil
1,470 wordsShould we begin to manufacture one of the most destructive and infamous substances on the face of the Earth once again? The engineers say yes, but the public says no. The United States stopped making this element with the ban on manufacturing nuclear weapons. But with the continuing problem with our ever diminishing energy sources, some want us to begin using more nuclear energy and less energy from natural resources.

Atom Bomb Arms Race
255 wordsUnited States, a super power, it came out of World War II with the strength of supremacy. None of the Axis bombs fell on American cities, nor did they hit the weapon factories. The other super power, USSR, lost many cities from the Nazis. Both lost many people during the war. In the 1940 s, United States dropped the atomic bomb on Hiroshima and Nagasaki. The Soviet Union, planning for protection for the future of their country after the Nazi battles, was determined not to be left with the weaker...

Leptons May Turn Quarks Is Called Particles
461 wordsIn about 1900 it was theorized that the atom was composed of smaller particles. An atom is actually a system consisting of a cloud of negatively charged particles called electrons surrounding a nucleus, composed of positively charged protons and of neutrons, which have no charge. In the 1960 s scientists discovered that protons and neutrons are composed of even smaller particles than first believed. The term quarks came about from an American physicist named Gell-Mann. He borrowed the term from ...
