The Manhattan Project Essay

On July 16, 1939, at the insistence of Leo Szilard and Eugene Wigner, physicist Albert Einstein sent a letter to President Franklin D. Roosevelt, warning the President of Nazi Germany's scientific research of the atomic bomb. His letter would acknowledge Roosevelt of the importance and the danger of this type of weapon in the hands of Adolf Hitler. Roosevelt immediately created the Advisory Committee on Uranium. After some time had passed, Einstein was forced to send another letter to Roosevelt because the government was not fully funding the committee because Leó Szilárd and Eugene Wigner were both born outside of the U.S. and were considered possible security risks. Roosevelt immediately ordered the government to give them the needed funds, and this brought about the Manhattan Project. After realizing the bomb would likely be used, Einstein regretted sending the letters to Roosevelt. Although a pacifist,

Then he went to teach at Berkley University.4 Another main person in the research project was Enrico Fermi. Fermi was a graduate of the University of Pisa, where he received his Ph.D. Fermi then went to the University of Rome teaching chemistry and biology. Fermi played a major role in the development of the bomb by creating a sustained nuclear fission chain reaction, which was critical to making the atomic bomb.4 Richard Feyman was another scientist which worked on the atomic bomb. Feyman graduated from Princeton where he excelled in physics and other scientific studies. Feyman's big duty on the Manhattan Project was to break big problems into smaller easier to do problems.4 The Manhattan Project, also had to have facilities for the research and testing of the atomic bomb. Some of the facilities built by U.S. Army Corps of Engineers included: power stations, factories, steel works, hospitals, laboratories, and housing for everybody that worked on the project.. Other facilities that were built for the construction of the bomb were plants to make the radioactive material needed to construct the bomb. Oak Ridge, Tennessee was used to make uranium which was used as an explosive to react with plutonium. The plutonium itself was made in Hanford, Washington.5 To make this explosion possible, a piece of uranium was fired at another piece of uranium to make the critical mass that was needed for an explosion. Critical mass is the exact amount of

This committee decided that the United States should retain nuclear superiority, in the event that international relations deteriorated following World War II (US Department of Energy). This decision is a foreshadowing of the Cold War, and nuclear arms race which followed the dropping of nuclear weapons on Japan. The interim committee also decreed that a regulatory system should be created to control the development of nuclear weapons, since other nations would inevitably obtain the technology needed to develop weapons. Possibly, the most influential decision made by the interim committee was to keep the details of the atomic bomb a secret, to maintain the shock effect, until after it had been dropped on Japan. Two atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki. The first bomb dropped was a uranium bomb, nick-named Little Boy, was untested before its detonation (US Department of Energy). The second, dropped after the Japanese did not surrender, was a plutonium bomb, nick-named Fat Man. The dropping of these bombs propelled the United States to a seat of world power, as they were the only country to obtain a weapon of mass destruction. The Manhattan Project became scientific and engineering feat, employing over 100,000 individuals. The exceptional organizational model the Manhattan Project provided, allowed for great scientific achievements in the later part of

They came, unwarned. On the 7th of December 1941, the Japanese executed a full-fledged attack on Pearl Harbor. They mercilessly created havoc, with attacks that caused the sinking of eighteen American ships, as well as 170 aircrafts. The casualties were dreadful, with 1,177 of those lost lives had been of the crewmen. The very next day, President Roosevelt declared war on Japan, and thus the United States’ involvement of World War II. Americans of every state were absolutely enraged and bent on their will for vengeance against the Asian country. Within the shadows of galvanized America, Robert Oppenheimer had set his infamous Manhattan Project into action. This project was so disclosed that only a limited number of men truly knew of its purpose. The clandestine project held prior securities to the point in which famous scientists had to use codenames in order to visit Los Alamos, even wives were kept in the dark, and only key scientists could bring their wives along with them. (Source D) This project had been the discreet creation of the Atomic Bombs. Time and time again, this topic had never really dissipated, its controversial who, what and whys prompting generations to debate its palpable purpose. Was the aim really focused for the “good of all?” Was it for America’s self-preservation and wish to promptly put an end to all of the suffering? Many Americans to this day still believe and argue for the usefulness of the atomic bombings, that the droppings were justified.

It became known that the German knew how to create an atomic bomb and FDR created a committee to study and create atomic bombs, named the Manhattan Project.The Manhattan Project was significant to the war because it led to the end of World War II and caused the Japanese to surrender to the Americans. The amount of people working together along with the cost and time which led to advancements in technology that was far ahead of any enemy. The creation of the bombs delivered a push in the advancement of science, innovation, designing, military and the entire of society into another age. It drew out the powerhouse that we consider today to be the United States of

The Manhattan Project was created out of the fear of their current enemy, Germany of making the first atomic bomb and using it in the war. The current President of the United States was Franklin Roosevelt. It was seen that Germany was making great advances in the war which worried many. But the people who were very worried were three prestigious scientists. Leo Szilard, Eugene Wigner, and Edward Teller who were Hungarian scientists who immigrated to the United States during the war. Szilard and the other scientists wished to advocate for the start of a program that put all efforts into making an atomic bomb. But of course they were very intelligent on how to get their cause across seriously. “Though the three men, particularly Szilard, were well known

     When the first atomic bomb was detonated in Alamogordo New Mexico on June 16, 1945, all the scientists involved in the Manhattan Project understood the great destructive power of radio-active isotopes. Although the atomic bomb was a very destructive force our world would not be as good without it. Because of the government funding involved in the project coupled with the need for an atom bomb, much research that otherwise may not have occurred took place in the US. The Manhattan project opened the door to nuclear advancements and applications.

Thesis Statement: The Manhattan Project was the American program for researching and developing the first atomic bombs because of the project it cost a lot of people their lives.

Leo Szilard was a Hungarian Physicist who dedicated himself to learning how to create a successful chain reaction to make an atomic bomb before the Germans had a chance to do so. Szilard convinced Albert Einstein to help research with him on how to create an atomic bomb. The “Einstein-Szilard” letter, sent to President Franklin D. Roosevelt led to the foundation of research into nuclear fission by the United States government. This ultimately encouraged the development of the program, the Manhattan Project.

had stopped the exportation of uranium from Czechoslovakian mines which they had taken over in 1938. He feared that Germany was trying to build an atomic bomb, while the United States was sitting idle. Although WWII had not yet started, Germany was clearly a threat, and if the Germans had a monopoly on the atomic bomb, it could be deployed against anyone, including the United States, without warning. Szilard worked with Albert Einstein, whose celebrity gave him access to the president, to produce a letter informing Roosevelt of the situation. Their warning eventually resulted in the Manhattan Project. Bomb opponents argue that the atomic bomb was built as a defensive weapon, not an offensive one. It was intended to be a deterrent, to make Germany or any other enemy think twice before using such a weapon against the United States. To bolster their argument, these

The Manhattan Project was assembled when “in 1939 the world’s scientific community discovered that German physicists had learned the secrets of splitting a uranium atom.” (US History 1) This caused many people to panic and it was later agreed that this issue of the Axis powers developing nuclear weaponry should be brought up to the United States, which could perhaps stop the Germans from causing unspeakable destruction to much of the world. Scientists Albert Einstein and Enrico Fermi, who both were living in the United States after leaving their previous countries to escape from either persecution or just leave the fascist state that Italy was currently in. Fermi was the scientist that went to Washington in order to express his concerns about this development of the splitting of the uranium atoms but not many others shared his concerns. Once Fermi

Finally, the bombing of Hiroshima and Nagasaki was unjustified because of the lack of testing. Although the project to design the first atomic bomb, codenamed the Manhattan Project, began in 1941, the first bomb was not ready to be tested until the month before it would be used in 1945. When it was tested at Trinity Site in New Mexico, the detonation caused unexpected results (“The Manhattan Project”). It caused “A blinding flash visible for 200 miles lit up the morning sky. A mushroom cloud reached 40,000 feet, blowing out windows of civilian homes up to 100 miles away. When the cloud returned to earth it created a half-mile wide crater metamorphosing sand into glass” (“The

The bomb uses a device called an altimeter to measure how far it is from the ground. It sends out radio frequencies which are bounced back to it. Microchips in the bomb determine how far it still has to fall, and when to detonate. The bombs also have fuses in the front which arm ! the bomb. They are not inserted until the bomb is ready to be launched.

Through the efforts of the “Manhattan Project” and the scientists within it, several nuclear bombs were created. Two of which, “Little Boy” and “Fat Man,” ended up being dropped on Japan. “Little Boy,” the only uranium bomb created was dropped on Hiroshima on August 6, 1945 (Batchelder 99-105). “Fat Man,” the second nuclear bomb ever used in warfare, detonated above Nagasaki on August 11, 1945 (Batchelder 95-105). The leaders of the United States, decided that dropping the newly developed atomic bombs on Japan was the smartest action they could take at the time, given the current situation that the United States and the world was in. Dropping the bombs on Japan was mainly motivated by the belief that human lives could be saved. A massive invasion of the Japanese mainland was the only other option if no bombs were going to be dropped. The fact that the Japanese main army of approximately two million had never before been defeated on top of the Japanese terrain which was much better suited for guerrilla warfare than the mechanical ways of the U.S. put estimated American deaths alone well over the deaths at Hiroshima and Nagasaki combined (Batchelder 114-118).

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).
