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...

Coal And Coke Diamond And Graphite Carbon
448 wordsCARBON AND HOW IT EFFECT OUR LIVES Although widely distributed in nature, carbon is not particularly plentiful (it makes up only about 0. 025 percent of the Earth's crust). Yet it forms more compounds than all the other elements combined. In 1961 the isotope carbon- 12 was selected to replace oxygen as the standard relative to which the atomic weights of all the other elements are measured; carbon- 14, which is radioactive, is the isotope used in radiocarbon dating and radio labeling. Elemental ...

August 6 1945 000 Tons Of Tnt
1,572 wordsThe Manhattan Project was the code name of the U. S. 's attempt to construct an atomic bomb during World War II. It was named after the Manhattan Engineer District of the U. S. Army Corps of Engineers, because a lot of it's earlier research was done in New York City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction. The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900 's. John D....

Million Years Ago Gulf Of Mexico
1,898 wordsIntroduction What is the oceans role in climate? The oceans play a vital and pivotal role in the distribution of life sustaining water throughout our planet. 86 % of the evaporation that occurs on earth is over the oceans. The oceans are the planets largest reservoir of water transferring huge amounts of water around the hydrological cycle. In fact the oceans dominate the hydrological cycle, for they contain 97 % of the global water inventory. The hydrological cycle can be disrupted by changes i...

Liquid Hydrogen Natural Gas
725 wordsHelium (Greek helios, "sun"), symbol He, inert, colorless, odorless gas element. In group 18 of the periodic table, helium is one of the noble gases. The atomic number of helium is 2. Pierre Janssen discovered helium in the spectrum of the corona of the sun during an eclipse in 1868. Shortly after it was identified as an element and named by the chemist Sir Edward Franklin and the British astronomer Sir Joseph Norman Lockyer. The gas was first isolated from terrestrial sources in 1895 by the Bri...

Base Pairs Double Helix
610 wordsThe molecule responsible for the transformation of characteristics form one generation to the next is called DNA. The genetic material, located in the chromosomes is a combination of acid and histones. DNA is made up of units called nucleotides. Nucleotides are made up of 3 components, a five carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. This base can be either adenine, guanine, thymine or cytosine. There are 2 strands of nucleotides in a double-helix they are anti-paral...

Source Of Energy Nuclear Fusion
519 words&# 65279; Energy From Nuclear Fusion Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10 - 15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy for us to sustain life on earth. For energy production on earth, different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two light forms (isotopes) of Hydrogen Deuterium and Tritium; even...

Nuclear Waste Half Life
977 wordsThe mathematical notion of infinity can be conceptualized in many different ways. First, as counting by hundreds for the rest of our lives, an endless quantity. It can also be thought of as digging a whole in hell for eternity, negative infinity. The concept I will explore, however, is infinitely smaller quantities, through radioactive decay Infinity is by definition an indefinitely large quantity. It is hard to grasp the magnitude of such an idea. When we examine infinity further by setting up ...

1,920 wordsOn Little Boy Little Boy On the morning of August 6, 1945, a B- 29 bomber named Enola Gay flew over the industrial city of Hiroshima, Japan and dropped the first atomic bomb ever used in war. The city went up in flames caused by the immense power equal to about 20, 000 tons of TNT. The project was a success. Hundreds of thousands died and still more were wounded. This was the final triumph that finally brought Japan to surrender. The effects of the bomb are still being seen but there is no doubt...

World War Ii Hydrogen Bomb
1,106 wordsThe Hydrogen Bomb Essay submitted by Anonymous Thesis Statement The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb, which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.

Paleo Ecological Reconstruction Paleo Ecological Evidence Organisms
1,100 wordsOne of the principal objectives of geologists studying sedimentary rocks is the reconstruction of the environment in which the rocks were deposited. Correct reconstruction may result in the discovery of oilfields, deposits of salts, or base metals, and provide insight to our earths past. As evidence to ancient environments the geologist has the structures, textures, and composition of the grains that make up the sediments, and the fossils preserved in them. Organisms are far more sensitive to, a...
