wisdom has it that America was justifiable after all by dropping a lethal bomb on a city full of civilians and soldiers‚ because their aim was to end the war. However‚ America was not reasonable by underestimating the human values‚ not warning them with the presence of an atomic bomb and leaving ever-lasting effects on a city. The atomic bombs that were dropped on Hiroshima and Nagasaki killed 100‚000 people. The atomic bomb is described as “the most dangerous threat the world has ever seen” (allvoices

of nuclear bombs. The two main types of nuclear weapons: atom bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of

On August 6‚ 1945‚ a plane called the Enola Gay dropped an atomic bomb‚ Little Boy on the city of Hiroshima. Hiroshima was a very industrial city; it had a military base and had not yet been bombed. The U.S. military thought Hiroshima would be a good target to display the destructive power of their new super bomb. Harry S. Truman‚ the president of The United States from 1945 to 1953‚ decided to drop the atomic bomb due to several reasons. First‚ he wanted to end the war as soon as possible‚ second

Effects of Poaching on Animals‚ Environment‚ and Communities Levi J. Stoesz Mountain Lake Christian Abstract Numerous research has been conducted on the effects of Poaching‚ and this paper will analyze these findings. Poaching negatively affects the communities‚ animals‚ and the environment. Research shows that poaching has dramatically increased over the previous decades and will continue to increase in the years to come. Poaching has the ability to destroy communities‚ cause extinction in

Enzymes are a major role in the process of accelerating chemical reactions. Environmental factors affect the enzymes‚ These environmental factors include ph levels and body temperature. While both of these environmental factors affect the enzyme‚ body temperature affects the enzymes the most and can result in death. Enzymes are affected by high body temperature. Enzymes are highly specific and they work at certain temperature levels depending if it’s hot or cold. However‚ when the

The Atomic Cafe The Atomic Cafe is a 1982 documentary film compiled of clips from government propaganda‚ training films‚ news stories‚ advertisements and other media from the 1940’s through the 1950’s. Many films were prepared by the U.S. government either for the military or for its citizens to view. The form of Atomic Cafe was unique for documentaries. It was produced entirely of different film sources edited together‚ without narration. The film made its points solely through the selection

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear

The Manhattan Project World War II started on September 1 1939‚ when Germany attacked Poland. By 1941‚ the Germans were ahead in the race for the atomic bomb. They had a heavy-water plant‚ high-grade uranium compounds‚ capable scientists and engineers‚ and the greatest chemical engineering industry in the world. Even before its entry into the war‚ the United States had become very concerned with the nuclear threat of the Axis powers. On October 11‚ 1939‚ President Franklin D. Roosevelt received
