How Is Atomic Bomb Used In History

During World War II, the Americans fought a two-front war, with pressure from both Japan and Germany. The United States, aware that Germany was threatening to build an atomic weapon, created a secret project to develop the technology first. Under the codename, the Manhattan Project, leading scientists carried out top secret research on fission and the technology needed to create the first atomic bomb. The immediate impact of the Manhattan Project was the dropping of two atomic bombs on Japan, ending the war in the Pacific. However, more important influences of this project can be seen following the detonation of the first bombs. The emergence of the United States as a world superpower following World War II, the tensions derived from the

The beginnings of the Nuclear Age started when Albert Einstein wrote to President Franklin Roosevelt warning him of a dangerous weapon the Nazis had begun researching, known as the atomic bomb. (1) Though, when President Roosevelt first read this letter, he was too preoccupied with events in Europe to be bothered with such ideas. He at the time did not take the creation of such weapon to seriously, nor did he believe America had the resources for such a task. (2) Finally, on October 19, 1939 President Roosevelt wrote back to Einstein stating that the United States had begun to research the power of uranium. (2) With the help of the British, whom reluctantly gave the United States leadership on this project, in June of 1942 the Manhattan Project had begun, though most of the world had no idea that this was even happening, not even Vice President Truman.

The first atomic bomb was dropped on the city of Hiroshima, one of the larger cities of the country of Japan. The announcement that an atomic bomb had been dropped on Japan came from Truman as a “scientific landmark and the age of atomic energy” . This power came as not only for the advancement of civilization, but also the ability for civilization to be

The fatal atomic bombings of the Japanese cities of Hiroshima and Nagasaki during the end of World War II are written down in history books today. This is because they had a drastic story behind them that changed the world and the lives of many civilians. The United States decision to drop the atomic bomb on Hiroshima and Nagasaki during World War II had both positive and negative results.

Even before the outbreak of War, the United States was concerned with a fascist regime in Europe researching in nuclear weapons. In retaliation, the United States began to fund an atomic weapon development program which became known as “The Manhattan Project” led by J. Robert Oppenheimer. Over the next several years, the Manhattan project started obtaining key materials such as Uranium-235 and Plutonium and testing prototypes until they reached a working model (Coroner).

The United States dropped their first atomic bomb over the Japanese city of Hiroshima on August 6th, 1945. The explosion was tragic, “90 percent of the city was wiped out and immediately killed 80,000 people; tens and thousand more would later die to radiation exposure” (Lemay and Paul). Innocent children and citizens would die.

On August 2, 1938, in the heat of World War II, Albert Einstein, a physicist born in Germany, sent a letter to Franklin Delano Roosevelt, the 32nd president of the United States. The letter suggested America to build an atomic bomb before the Nazi Germany does. However, it took more than two months for the letter to reach Roosevelt. On October 19, 1938, Roosevelt agreed, replying, “I found this data of such import that I have convened a Board … to thoroughly investigate the possibilities of your suggestion regarding the element of uranium” (“President Roosevelt's response to Dr. Einstein”). As a result, America held a secret program, code named Manhattan Project, and started to build new, destructive weapons in a laboratory in Los Alamos,

On the clear morning of August 6, 1945 in Hiroshima, Japan, the world was hit with a total shock, that went down in history as a day for the history books. This day, the city of Hiroshima was blasted by the world’s first atomic bomb, which sent the grounds quaking, and leaving thousands dead. The debates for years since the bombing were having us all wonder if the attack was a military necessity or not. Considering both sides of the argument, it is clear to me that the bombing was the best plan for ending the world war. The use of the bomb saved more lives than it took.

On the morning of August 6, 1945, a B-29 Bomber that was names Enola Gay had flew over the City of Hiroshima Japan and dropped the first atomic bomb to have ever been made. The motive for the creation and research of the bomb was a direct result of the Japanese bombing on Pearl Harbor. When the bomb was finalized after all the research of splitting atoms and combining plutonium and uranium and knowing what to use, many tests were done and the bomb was presumed ready. But no one could have guessed the magnitude of this bomb. The city was engulfed in flames as the power of the bomb being equivalent to 20,000 tons of TNT being dropped exploded. There was much work that went into making this project a success amongst all others. There was a wide variety of scientific brain knowledge, civilian knowledge and much military knowledge and assembly to make this project happen.

Before the United States dropped the bomb, they allowed Japan a chance to surrender. On July 26, 1945, the allies issued the Potsdam Declaration. This treaty was meant to make Japan surrender without a war. This was a warning that Japan will undergo harsh and utter destruction if they refused the declaration. Two days later Japan stated that they were going to ignore the Potsdam Declaration (“Was the Atomic Bombing”).

Necessity is the mother of invention. Michael Blow wrote in his book, The History of the Atomic Bomb, that the United States was building an atomic weapon for the main purpose of beating the Germans to the creation of the bomb (95-96). After uranium was used to create atomic fission in Berlin in 1939, Albert Einstein and other scientists wrote a letter to Roosevelt, talking him into government funding for atomic research in America (Foner and Garraty, “Manhattan” n. pag.). In a bit of irony, American leaders believed that the Germans, in the race to create the ultimate weapon, were beating them. In actuality, however, they never got far in their research, and America defeated them by a sizeable amount (Blow 96). In the United States, research for the “Manhattan Project,” the code name for the secret project to use atomic energy to create a bomb, expanded all around the country. This included universities such as Columbia, Princeton, California, and Chicago. While the research had been independent and government funded up until the middle of 1942, the army took over guidance of the project at that point. The possibility of an atomic bomb had become too realistic to keep the research in the private sector (Foner and Garraty, “Manhattan”).

Between 1944 and 1945, the Allies attacked Germany and the U.S. advanced across the Pacific to the doorsteps of Japan. In these last two years of war, Americans also created a new form of weapon that changed both warfare and global politics. With advances in technology, the Allied and Axis scientists were able to construct the most deadly, crucial weapon, the atomic bomb. Its creation started in 1942, when President Roosevelt presented the Manhattan Project as a priority in the development of the atomic bomb. However, the decision to use this mortal weapon fell into the hands of the new president, Harry Truman. He had to decide whether to save the lives of millions of Americans or to kill thousands of innocent Japanese families.

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”).

On August 6, 1945, during World War II an American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima. Three days later, a second B-29 dropped another A-bomb on Nagasaki, killing an estimated 40,000 people. Japan’s Emperor

In the summer of 1939, Einstein, along with another scientist, Leo Szilard, was persuaded to write a letter to President Franklin D. Roosevelt to alert him of the possibility of a Nazi bomb. President Roosevelt could not risk the possibility that Germany might develop an atomic bomb first. The letter is believed to be the key factor that motivated the United States to investigate the development of nuclear weapons. Roosevelt invited Einstein to meet with him and soon after the United States initiated the Manhattan Project (M. Talmey).
