Robert Oppenheimer: The Manhattan Project
Born out of a small research programme in 1939, the Manhattan Project's roots lay in the United States’ fears that, since the 1930s, Nazi Germany had been trying to develop nuclear weapons. Efforts towards upgrading this project moved forward in 1942, when it was transferred to the authority of the United States Army as the “Manhattan Project”. Formally designated as the Manhattan Engineer District (MED), this project ran from 1941–1946 under the control of the United States Army Corps of Engineers administered by General Leslie R. Groves. The scientific research was directed by American physicist J. Robert

    In August of 1939, President F. D. Roosevelt was made aware of the possibility that German scientists were racing to construct an atomic bomb. He was also warned that Hitler would be more than willing to resort to such a weapon. Roosevelt, in response to this set up the Advisory Committee on Uranium, which consisted of both military and civilian representatives. In order to reach their own advancements in the nuclear field faster than Germany they were to study the current state of research on uranium and to recommend an appropriate role for the federal government. At Columbia University a limited military funding for isotope separation and the work on chain reactions were performed by Enrico Fermi and Leo…

    The United States practiced isolationism for many years before entering World War II, until the bombing of Pearl Harbor. Government funded atomic weaponry research had begun not long before the attack, and this has led people to believe that the Manhattan Project, a descendent of the program, was a knee-jerk reaction to the bombing. According to writer Brenda Wilmoth Lerner in her article on the Manhattan Project for the Encyclopedia of Espionage, Intelligence, and Security, Roosevelt ordered, in December of 1941, that research was to begin regarding the plausibility of building an atomic weapon, just following the bombing of Pearl Harbor (246). Although misconceptions exist that the Manhattan Project was a direct response to the bombing of Pearl Harbor, it was not, as shown by the initiation of early government funded atomic research; the beginning of atomic weapons research well before the attack; and the establishment of the Manhattan Project significantly post Pearl Harbor.…

    As Team Leader of the Deep Freeze Folk, it was my responsibility to organize all of the research pooled together by my Technical Advisor and Systems Engineer and compile it into a presentation that was not only accurate and educational, but a little fun too. This is the last quarter of my undergraduate degree, and along with nearly six years in the Army Reserves and a ton of presentations under my belt, I have found that getting people to laugh helps foster attention and learning. The information our team was able to gather was indeed factual, with former, current, and future NASA missions as our main source of information. However, when it comes to the colonization of a celestial body that is far beyond our current capabilities, it involves…

    The world’s greatest physicists and mathematicians took part in commanding the efforts during World War II, the project was projected to cost a heaping $20 billion due to the production of the first uranium and plutonium bombs. Albert Einstein influenced the beginning of the Manhattan Project. In collaboration with Leo Szilard, Einstein wrote a letter to President Franklin D. Roosevelt in 1939, to inform him of possible German nuclear weapons research and proposing that the United States began its own research into atomic energy. The American quest for nuclear explosives was driven by the fear of Germany’s very own Adolf Hitler and the fact that he would invent and gain military advantage. This project took a little less four years, the first atomic bombs were designed and built at a site in Los Alamos, New Mexico. The Manhattan Project produces three bombs: the first bomb known as “Gadget” and was used as a test model. Due to the enormous expense and slow production rates for explosive material, no further tests were conducted. The second bomb, known as “Little Boy” was detonated over the city of Hiroshima in August 6, 1945 during World War II, and the final bomb, “Fat Man” was detonated over the city of Nagasaki three days later. Which led to Emperor Hirohito to announce his country’s surrender. Nuclear facilities were built at Oak Ridge, Tennessee and Hanford, Washington. The main assembly plant was built at Los Alamos, New Mexico. The reason it was named the Manhattan Project was to trick enemy countries into thinking any development would be taking place in Manhattan, New York. The government was taking a chance to take enemy fire or possible bombing of an innocent state. This was made to believe that there was some sort of project taking place in a location that had nothing to do with…

    The Manhattan Project and the atomic bomb that it produced helped bring an end to World War II. The Manhattan Project was the code name for the effort to develop atomic weapons for the United States during World War II. Not only did it push other countries to develop nuclear weapons, with the potential of annihilating millions of lives, but it also caused much civil unrest as many Americans feared another war, only with the outcome being much more devastating. At this time in history, 1941 to 1945, a catastrophe of this magnitude was unprecedented and contributed to the feelings of social anxiety and unrest. The Manhattan Project, and the atomic bomb, had many, both positive and negative, effects on American society.…

    The Manhattan Project was one of the largest endeavors conducted by the United States. Today, it is a well known piece of history, but at the time the Manhattan Project was completed confidentially. The Manhattan Project employed thousands of civilians, and spent billions of dollars (adjusted for inflation) in secrecy. Approximately 200,000 people died as a result of the Manhattan Project and it is widely debated whether the bombing of Japanese cities with atomic bombs was necessary. Because the Manhattan Project was the cause of such significant scientific and engineering feats, as well as because it resulted in one of the most controversial decisions of all time, it is important to study the Manhattan Project thoroughly.…
