Nuclear Arms
On August 6, 1945, Hiroshima was devastated by "a most cruel and terrible new bomb," as described by Emperor Hirohito, one of the Axis leaders during World War II. Since then, nuclear weapons have become a major threat to humanity as more and more missiles, bombs, and other weapons are created by different countries. Today, many nations, including the United States and Russia, are working together to disarm their stockpile of nuclear weapons.
Germany first started developing a fission bomb in 1939. Albert Einstein, along with other scientists, realized this and wrote to President Roosevelt regarding the threat to the Allies. Shortly after, the United States began serious efforts to produce an atomic bomb, later known as the ‘Manhattan Project’.
When the Manhattan Project first started, its first objective was to provide a source of Uranium 235, a highly fissionable material. Unfortunately, this compound was very rare, with only one atom of U-235 to every five hundred of Uranium 238, which was virtually worthless in creating nuclear weapons at the time...
The U.S. decided to develop the atomic bomb based on the fear they had for the safety of the nation. In August 1939 nuclear physicists sent manuscripts to Albert Einstein in fear the Germany might use the new knowledge of fission on the uranium nucleus as way to construct weapons. In response, on August 2, 1939, Einstein sent a letter to President Roosevelt concerning the pressing matter to use uranium to create such weapons before Germany (Doc A-1). To support the development of the atomic bomb, President Roosevelt approved the production of the bomb following the receipt that the bomb is feasible on January 19, 1942. From this day to December of 1942, many laboratories and ...
This protect came to be famed as the, “Manhattan Project.” The starting gun has been fired and the race to the newest weapon was on! Initial thought of the atomic bombs would be much too heavy to carry them via aircraft. Roosevelt approved of the “Uranium Committee” and awarded them $6,000.00 dollars to mine the uranium and graphite in order to craft this ultimate weapon.
Near the end of the Second World War, America and Japan continue to fight with no signs of surrender in sight from either side. President Truman warned the government of Japan that he would use weapons of mass destruction if there was not an end to the war, but they refused to surrender. The decision that Japan made to ignore President Truman left him with two choices; develop the atomic bomb or invade Japan with American forces and allies. After careful consideration, President Truman made the choice to develop and use the nuclear bombs as a way to end World War II. On August 6, 1945, the president unleashed the massive weapon of destruction on the city of Hiroshima dropping the atomic bomb code named “Little Boy”. A few days later on August
In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
During last 50 years of development, the nuclear bomb, as the ultimate weapon became the peacekeeping force on the earth. The nuclear bomb was developed in Manhattan project during the WW II and was successfully tested in the New Mexico on July 16 1945. At this point started the change of nuclear weapon from ultimate weapon to political weapon. USA decided to use the atomic bomb to defeat Japan in order to save around 500.000 lives of American soldiers that were needed to end the war and in the summer 1945 the USA dropped two bombs on Hiroshima and Nagasaki. The nuclear weapon raised the confidence of USA but president Truman did not ordered its mass production because at that time he saw no explicit political function for the bomb. USA even tried to internationalize control of the bomb under the UNITED NATIONS but the Soviets were reluctant to support American plan for two reasons. To stop soviet nuclear program before developing the first soviet bomb would give Americans permanent lead in nuclear weapons technology. Soviets believed that instruments of force always have political capabilities. For the Kremlin weapons were political tools. This led Americans to the same conclusion. The beginning of Cold War created several political functions of nuclear weapons: nuclear deterrence, alliance building, and international prestige.
In October of 1939, after the start of World War 2 (WW2), Franklin D. Rosevelt received a letter from a Jewish Scientist in Nazi Germany. This man named Albert Einstein had claimed to have created a blueprint for a weapon using the power of nuclear fission said to be extremely potent and effective. After receiving this letter President Rosevelt had assembled a team to create this weapon, and the team had completed it at the height of the war. The atomic bombs had been dropped on the city of Hiroshima on august 7th and on Nagasaki on August 9th 1945. T...
At 5:30 AM July 16th 1945, the nuclear age had started. The world’s first atomic bomb was detonated. On August 6th 1942 at 8:15 AM, an American B-29 bomber, the Enola Gay, dropped a perfected atomic bomb created by the Americans, over the city of Hiroshima hoping to end the war. Thousands of people died in the two cities in Japan. They were Hiroshima and Nagasaki “the Manhattan Project”. The research and development project that produced these atomic bombs during this time was known as “the Manhattan Project”.
Throughout half the century of the 19’s hundreds a period of new advancements in the creations of a bomb had arisen. On August 8th, 1939 President Roosevelt received a letter from Albert Einstein which ended up being the fundamental support in the creation of the Atomic Bomb. There are two types of atomic bombs fusion and fission, the first atomic bomb was created in 1939 by the Manhattan Project, three weeks later after its first test, it was used in an actual war. It’s capable of wiping out a whole entire city and killing instantly anyone in its way. Now we have better more precise bomb know as hydrogen bombs, these bomb use the energy released when the nuclei of a hydrogen come together or fuse, unlike a fission bomb which gets its energy from when the nuclei of a heavy element such as plutonium or uranium splitting apart creating a chain reaction leading to a large explosion.
In 1939 rumor came to the U.S. that Germans had split the atom. The threat of the Nazis developing a nuclear weapon prompted President Roosevelt to establish The Manhattan Project. Oppenheimer set up a research lab in Los Alamos, New Mexico and brought the best minds in physics to work on the problem of creating a nuclear weapon. Although most the research and development was done in Los Alamos, there were over 30 other research locations throughout the project. After watching the first nuclear bomb test Oppenheimer was quoted as saying simply “It works.”.
When the United States caught word that Germany was close to creating the atomic bomb, J. Robert Oppenheimer and other scientists wanted to create it first, for the U.S. After three years of research, the first small atomic device was exploded on July 16, 1945 in the lab at Los Alamos. Having proved their concept worked, a larger scale bomb was built. Less than a month later, atomic bombs were dropped on Hiroshima and Nagasaki in Japan (Rosenberg).
The Manhattan Project took place during World War II, in the late 1930s and early 1940s. Germany was already developing an atomic weapon. In 1939, Albert Einstein wrote to president Franklin Roosevelt, explaining an idea he had for developing a nuclear weapon, and saying they should begin to research it. Roosevelt agreed with Einstein, and organized a research committee. In 1942, Roosevelt created a secret government project to build a nuclear weapon. This project was titled the Manhattan Project, and was the largest secret government project in US history.
The world’s conflict over nuclear weapons all began with President Truman’s decision to drop the bombs on Hiroshima and Nagasaki. World War II was coming to a close but Japan would not surrender. So, on August 6, 1945, the bomb Little Boy was dropped on Hiroshima. It was triggered by a gun mechanism where a small piece of uranium-235 was fired down a barrel into a larger piece. This caused an explosion of 15 kilotons, or 15,000 tons of TNT, killing 90,000 to 166,000 people. Surprisingly, Japan did not surrender, so on August 9, 1945, the bomb Fat Man was dropped on Nagasaki. It was triggered when shock waves from high explosives set off the plutonium-239 core. It caused an explosion of 20 kilotons, or 20,000 tons of TNT, and killed 60,000 to 80,000 people. This second attack really sent the message to Japan, and they finally surrendered on August 15, 1945. World War II was finally over, but the Cold War began with the reveal of the United States’ nuclear power. It is believed that dropping the bombs saved both Japanese and American lives by ending the w...
One of the first inventions but more so of a discovery was the idea of nuclear fusion. It was discovered by a German scientist in february of 1939. This led to the invention of the atomic bomb. The atomic bomb was only used twice both times by the U.S. near the end of the war first on Hiroshima then on Nagasaki(Atomic Bomb).
The development and usage of the first atomic bombs has caused a change in military, political, and public functionality of the world today. The bombings of Hiroshima and Nagasaki revolutionized warfare by killing large masses of civilian population with a single strike. The bombs’ effects from the blast, extreme heat, and radiation left an estimated 140,000 people dead. The bombs created a temporary resolution that lead to another conflict. The Cold War was a political standoff between the Soviet Union and the United States that again created a new worldwide nuclear threat. The destructive potential of nuclear weapons had created a global sweep of fear as to what might happen if these terrible forces where unleashed again. The technology involved in building the first atomic bombs has grown into the creation of nuclear weapons that are potentially 40 times more powerful than the original bombs used. However, a military change in strategy has came to promote nuclear disarmament and prevent the usage of nuclear weapons. The technology of building the atomic bomb has spurred some useful innovations that can be applied through the use of nuclear power. The fear of a potential nuclear attack had been heightened by the media and its release of movies impacting on public opinion and fear of nuclear devastation. The lives lost after the detonation of the atomic bombs have become warning signs that changed global thinking and caused preventative actions.
In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
