According to Merriam-Webster, nuclear fission is defined as “the splitting of an atomic nucleus resulting in the release of large amounts of energy” (Nuclear Fission). In the book Remembering the Manhattan Project: Perspectives on the Making of the Atomic Bomb and Its Legacy, Richard Rhodes, an American journalist and historian, states that fission was essentially discovered by accident. On December 21, 1938, German physicists, Otto Hahn and Fritz Strassman, were performing an experiment in which they bombarded uranium atoms with neutrons (Rhodes 17). They saw that this procedure created mutated atoms that had strange characteristics. Hahn and Strassman found that the neutrons split the nuclei of the uranium in half producing radioactive barium and krypton (Rhodes 18).
(Wilkie) People know that despite efforts to keep control on the old Soviet stockpile and waste, terrorists are getting the plutonium and uranium needed to make nuclear weapons to kill masses of people. This is kind of the history of the nuclear & atomic bomb: (all from Williams) The first atomic bomb was thought up by Albert Einstein in the late 30's. In 1942 Enrico Fermi brought about first nuclear reaction with isotope Uranium 235. From this the Manhattan Project was brought about and took place in Los Alamos, New Mexico. Then July 16, 1945 near Alamogordo, New Mexico world's first atomic bomb was set off.
Soon after the first bomb test, atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki in 1945. The first hydrogen bomb was developed by a team of United States scientists and was first tested on November 1, 1952. After World War II, a new age of military strategy occurred. The United States built up massive nuclear weapons arsenals and developed highly sophisticated systems of delivery and defense. Today's intercontinental ballistic missiles (ICBMs) carry one or more multiple, independently targeted reentry vehicles (MIBVs), each with its own nuclear war head.
Harry S. Truman was the 33rd president of the United States of America. He became president because Franklin D. Roosevelt died during his term; Truman was Roosevelt’s Vice President at the time. Truman found himself facing some of the greatest challenges met by any 20th-century president. He discovered in July 1945 that some scientists working for the United States government had successfully tested an atomic bomb in New Mexico. President Truman wanted to use the atomic bomb to end the war in the Pacific, but with fewest U.S. catastrophes.
The first atomic device was successfully tested in New Mexico on July 16, 1945 (“Outline History of Nuclear Energy” 1). The first use of the atomic bomb is on Hiroshima and Nagasaki in 1945. After Germany's defeat in 1945, German scientists were recruited to work in a joint effort bomb program (“Outline History of Nuclear Energy” 1). In 1954, the Sov... ... middle of paper ... ...sion or computer in a lifetime than living next to a power plant (Snedden 5).

A group of scientists from around the world named the Manhattan Project was created by the United States. The projects one goal was to invent the first nuclear weapon, and they successfully tested the first nuclear weapon in 1945. A nuclear weapon is a device that derives its energy from nuclear reactions. These reactions are the breaking and joining of atom bonds which creates tremendous amount of radiation. Nuclear bombs contain uranium atoms, and when detonated they become more powerful than any other weapon ever made.
Nuclear weapons have a long-lasting and devastating effect on the world for many years after an initial explosion. Fallout from United States atmospheric testing from 1945 to 1963 killed an estimated 70,000 to 800,000 people worldwide. People who have worked in the early nuclear weapons programs have been exposed to significant amounts of radiation (Schwartz 395). When a nuclear weapon goes off, there are four basic types of explosions: air bursts, surface blast, subsurface burst, and high altitude burst. An air burst occurs when a weapon is detonated at a height so the fireball does not reach the surface of the earth (Effects Nuclear Explosions).
The Atomic Bomb In 1945, such a mechanism was created. The atomic bomb was created after many years of the study of atoms. Finally, a way to split the atoms was born. Germany was the first to try making a bomb. Efforts failed, but were picked up by the United States.
The 100 foot tower which housed the bomb was totally destroyed by the blast. ("World War II", 1997, 1-2). After the bomb exploded, Robert Oppenheimer, the head of the Manhattan Project, said, "Behold. I have become death, destroyer of worlds." (Hoare, 1987, 18) When Harry Trum... ... middle of paper ... ...p; The United States, as well as the Allied forces, saved many lives by dropping the atomic bomb.
Leo Szilard, a Hungarian scientist, first wrote a letter to President Roosevelt signed by Albert Einstein that stated the U.S. needed to create an atomic bomb. This came about when Szilard realized the danger that would arise if Germany made the first atomic bomb (Long). Einstein was the one who warned the U.S. that Germany had been conducting research into nuclear weapons and didn't want the Nazis to build one first. The first successful test had been conducted in New Mexico on July 16,1945 with a plutonium bomb, by which time Germany had already been defeated (A&E). The next step was to go after Japan.
