Atomic energy is “the energy that is released through a nuclear reaction or radioactive decay process”(u.s.nrc). Jordan Termine stated, “According to Einstein’s researches, in 1939, he concluded the possibility of setting up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power would be generated”(findingdulcinea).
The scientists that have significantly contributed to the development of nuclear weapons are: Albert Einstein, who first explored the nuclear fission and its potential use as a weapon. Another key player in this field was General Leslie Groves, who conducted the first nuclear test in New Mexico under a project called ‘memorandum of secretary of war’. J.Robert Oppenheimer, also known as the father of the atomic bomb, “was appointed scientific director of the Manhattan Project. Oppenheimer dubbed the first denotation the “Trinity” Test”(findingdulcinea).
Atomic weapons were developed by the U.S in World War II because during the early years of the war the German forces showed the world the strength of their military weapons. “President Franklin Roosevelt realized that in order to win the war the United States would need to develop modern weapons of its own. For this reason, he established a national defense research Committee to further develop Einstein’s researches with the aim of building the atomic bomb before the Germans do”(manythings). To close a dramatic chapter of brutal fighting during World War II, the United States used the atomic bomb in august 6, 1945 bombarding Hiroshima, Japan. The second bombing was “three days later when the United States dropped another atomic bomb over the city of Nagasaki, Japan”(Teachinghistory).

Nuclear energy is one of the most important sources of energy in the world. The discovery of nuclear energy is an important invention for humanity for its many peaceful uses. “Today, 439 nuclear power reactors produce approximately 16 % of the world’s electricity” (un.org). Nuclear energy is also considered useful for dealing with the climate change challenges we are facing nowadays, many other fields which benefited from nuclear energy such as; “health care and nutrition, water resource management, food security, sustainable development, and nuclear safety and security” (state.gov). The United States adopted many programs for peaceful uses of nuclear energy, activities supported by the united states include; Sterile Insect Technique (SIT), Program for Action for Cancer Therapy (PACT), Support for nuclear power infrastructure.
On August 6, 1945, the U.S. dropped the world’s first atomic bomb over Hiroshima. Three days later, a second bomb was dropped on Nagasaki. On August 15th, the Japan announced unconditional surrender in World War II. To this day historians still discuss why the U.S. decided to use the atomic bombs. Orthodox historians argue that the decision to drop the bombs was a military one designed purely to defeat the Japanese.
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”).
Teller, who is a “Hungarian-born atomic physicist” and “known as the "father" of the hydrogen bomb”, was at the forefront when it came to the design of the Teller-Ulam Hydrogen Bomb (Hydrogen Bomb Exploded). Stanislaw Marcin Ulam, mathematician who developed the idea of the lithium hydride bomb, was the other half of that perfect combination. Although there was excitement for the U.S. being the first to be the bomb, some scientists did not share that excitement. Not all people agreed with the idea of building this bomb, some people had their doubts. For example, Julius Robert Oppenheimer was a highly known theoretical physicist and Director of the Los Alamos Laboratories.
Upon entering World War II as a result of Japan’s attack on Pearl Harbor on December 7, 1941, the United States faced the burden of fighting two dangerous military powers: Germany and Japan. Germany was developing new, secret weapons that could very likely be a potential threat to the United States. It had been reported that German scientists were experimenting with splitting the atom, which would release an enormous amount of energy.1 Whoever was successful with this tactic had the power to control the world. After receiving this information, President Harry Truman went into shock. The United States began atomic research shortly after with the help of physicists Leo Szilard and Albert Einstein.2 This effort was code-named the Manhattan Project, which took place in Los Alamos, New Mexico. The project involved more than half a million people working to design and predict the results of an atomic bomb. After spending two billion dollars, a test called Trinity was cond...
Atomic Bomb in World War 2 During World War II the United States government launched a $2 billion project. This project, known as the Manhattan Project, was an effort to produce an atomic bomb. This project was taken on by a group atomic scientists from all over the world.
When President Truman authorized the use of two nuclear weapons in 1945 against the Japanese in the cities of Hiroshima and Nagasaki to end World War II, the nature of international security was changed irreversibly. At that time, the United States had what was said to have a monopoly of atomic bombs. Soon thereafter, the Soviet Union began working on atomic weaponry. In 1949, it had already detonated it first atomic bomb and tensions began to heat up between the two countries. With the information that the Soviets had tested their first bomb, the United States began work on more powerful weapons1, and a fight for nuclear superiority had begun.
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 ...
After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.
Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely solely on nuclear technology. This technology was developed through the process of creating the first atomic bomb and would not exist if not for the advancements made during the Manhattan project.
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
Atomic bombs were the first nuclear weapons to be developed, tested, and used. In the late 1930s physicists in Europe and the United States realized that the fission of uranium could be used to create an extremely powerful explosive weapon, in this case, the atomic bomb. How did the Americans build this weapon of mass destruction? What happened to the Japan after the bombing? Finally, How did this impact war?
The atomic bomb was first created in the early twentieth century. Physicists in the United States and Europe had discovered that the fission of uranium could be used to create a deadly explosive weapon. A letter was sent to U.S. president Franklin D. Roosevelt by Albert Einstein that described this discovery and warned him of its potential dangers if developed by other nations. The Manhattan Project was established by the U.S. government in 1942 so the country could develop an atomic device. A team under the command of United States Army Brigadier General Leslie R. Groves designed and built the first atomic bombs, directed by J. Robert Oppenheimer. This type of bomb was first tested at Alamogordo, New Mexico, on July 16, 1945. The amount of energy that was released by this explosion alone was equivalent to twenty thousand tons of TNT.
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 has created a global sweep of fear as to what might happen if these terrible forces were 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 come 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.
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).
