Lower Manhattan

You have heard two reasons why dropping the atomic bombs in Japan was not justified and unnecessary. But perhaps the most compelling reasons why dropping the bomb was not justified is that the United States was weeks or months away from Japan surrendering and the war ending before dropping the bombs and killing hundreds of thousands of innocent people. As you will hear from General Mitsuru Ushijima, Japan was already losing the war. The country was surrounded by US troops, Americans…

German physicists had learned the secrets of splitting an uranium atom (“The Manhattan Project”). In late 1941, the American effort to design and build an atomic bomb received its code name -- the Manhattan Project, which included scientists David Bohm, Leo Szilard, Eugene Wigner, Otto Frisch, Rudolf Peierls, Felix Bloch, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fachs, and Edward Teller (“The Manhattan Project”). The chief among the people who unleashed the power of the…

The attack on Pearl Harbor was a complete surprise. Even after prior sightings of strange movement in the fleet, military personnel failed to conclude that a surprise attack might occur. By 8:00 am, Battleships were destroyed and heavy smoke filled the air. The Japanese attacked twice, the first was for aircraft and the second wave attack was for battleships and ship facilities. At 8:10 am, 1,800-pound bomb smashed through the deck of the battleship USS Arizona, causing the battleship USS…

The Manhattan Project was the design and creation of the first atomic bomb during WW2. In this research paper, I will be going into detail of the creation of the atomic bomb, the purpose and the overall impact of the event that happened in 1942. First of all, What is an atomic bomb? An atomic bomb is a weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of such heavy elements as plutonium or uranium. It is considered a…

believed that the energy harvested could be useful to making such powerful weapons. The Manhattan Project was a code name given in 1941 for the devising of the atomic bomb. At one point, there were over 120,000 Americans that were employed in this project, and almost two billion dollars were put into research. Isabella Karle is a scientist who worked in the field of crystallography, and during the Manhattan Project she worked on plutonium chemistry. With her advances in molecular structures,…

Underwater detonation of 23 kiloton nuclear weapon, 1946 This detonation, known as the Baker Test, was part of Operation Crossroads in Bikini Atoll in the Pacific. The purpose of the tests was to investigate the effect of nuclear weapons on warships. The Crossroads tests were the first of many nuclear tests held in the Marshall Islands, and the first to be publicly announced beforehand and observed by an invited audience, including a large press corps. A fleet of 95 target vessels was assembled…

In June of 1940, President Franklin D. Roosevelt had established the National Defense Research Committee (NDRC) to conduct scientific research to solve the problems underlying the development, production, and use of mechanisms and devices of warfare. Similarly, to an effort that had occurred during World War I under the Council of National Defense. There were several problems impacting the success of the NDRC. The agency had neither the authority nor the money to move research through…

this powerful creation also came with catastrophic results. The effects were dangerous and harmful to living things, and they are still felt to this day. This infamous event started with the Manhattan Project in New York, which was led by physicist Julius Robert Oppenheimer and General Leslie Groves. The Manhattan Project caused other mini projects around the United States to appear, each contributing components for the atomic bomb, like Plutonium and Uranium. The…

On August 6, 1945, two atomic bombs were launched and dropped on Hiroshima and Nagasaki Japan. According to History.com's article on the "Bombing of Hiroshima and Nagasaki", over 120,000 people died instantly including the 11,000 that suffered from blast induced injuries and burns due to radiation. Innocent lives such as senior citizens, animals, families with small children and babies died tragically. 90% of the population in those two cities were wiped out. As of 2017, the United States…

The development of nuclear weapons led to the use of the atomic bomb in world war two. The atomic bomb was made and tested in the United States, it proved to be successful and was dropped on Hiroshima, and Nagasaki, which were two cities in Japan. The atomic bomb was a new weapon that was bigger and caused more destruction than any bomb previously invented. It caused widespread destruction where the first bomb hit Hiroshima, and followed with the second bomb three days later in Nagasaki causing…
