This concerned the US, so Albert Einstein and a refugee from Germany warned President Roosevelt that Germany was planning on building an Atomic Bomb. They then started an American Research Project on it. Roosevelt responded by setting up an Uranium Committee whish reported that it would be possible to create an Atomic Bomb . Research on Atomic Bombs increased when the United states entered World War II. soon after word American and British forces joined to work together against Germany, this ends being the Manhattan Project.
The Atomic Bomb John D. Krause American History 212 Dr. Matthew McCabe December 10, 2009 On August 2, 1939, just before the beginning of World War II, Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein told Roosevelt of efforts in Nazi Germany to purify U-235, which might in turn be used to build an atomic bomb. It was shortly thereafter that the United States began the Manhattan Project. Simply put, the Manhattan Project was committed to expedient research and production of a viable atomic bomb. Needless to say, the atomic bomb has been one of the greatest sources of controversy and debate since the two bombs were detonated.
In 1941 a man named Russel Meredith of Northrop Aircraft perfected using a direct current, gas-shielded welding process to weld magnesium. He named the process Heliarc because it used a tungsten electrode arc and helium as a shielding gas, but it is often referred to as tungsten inert gas welding (TIG). The official American Welding Society term is gas tungsten arc welding (GTAW). Linde Air Products purchased the patent and name from Northrop and continued to develop the process. They came out with air-cooled and water-cooled torches, gas lenses to improve shielding and other accessories that increased the use of the process.
A Response to: The Day After Trinity HIS 262 Ellen Bardo Pennsylvania College of Technology February 13, 2010 The Day After Trinity is the documentation of the development of the atomic bomb, the original weapon of mass destruction, by the United States due to the belief that Hitler and Nazi Germany were pursuing the development of the atomic bomb. This concern, with regard to the possible consequences that would result from the development of the atom bomb by Nazi Germany, justified the entry of the United States into the race to develop the ultimate weapon. Robert Oppenheimer, prominent physicist, joined the research group dedicated to developing the atom bomb in the early 1940’s. The team consisted of Nobel Laureates
In October 1939, just after the outbreak of World War II in Europe, the President of the United States Franklin D. Roosevelt received a letter from physicist Albert Einstein and his Hungarian colleague Leo Szilard, letting him know that a bomb of unprecedented power could be made by tapping the forces of nuclear fission. The two scientists, who had fled from Europe in order to escape Nazism, feared that Hitler-Germany was already working on the problem. They fear this because if the Germans were to be the first to develop the envisaged "atomic bomb," Hitler would have had a weapon in his hands that would make it possible for him to destroy his enemies and rule the world. Einstein and Szilard urged the government of the United States to join the race for the atomic bomb to end this nightmare. Roosevelt agreed to join and for the next four and half years a huge, secret effort was launched in cooperation with the United Kingdom.
The discovery of the nucleus, the idea of radiation, and the fact that the splitting of atomic nuclei could lead to a massive release of energy all led to the development of the atom bomb. The Manhattan Project was a project to develop the atomic weapons to be used during World War II by the United States. The project came about mostly by scientists' fear that Nazi Germany was investigating its own nuclear weapons for use. It ran from 1941 to 1945 and was successful at developing and using the first atomic bombs. Hiroshima was a minor supply and logistics base for the Japanese military and this made it a good target for the U.S. military.
However, the nuclear arms race highlighted the dangers inherent to the development of nuclear weapons and encouraged the superpowers to use alternative methods of warfare and to restrict the development of nuclear weapons. The end of the US’s nuclear monopoly with the USSR’s successful testing of the atomic bomb in 1949 prompted a rapid development of more powerful weapons. The US responded with the Hydrogen bomb in 1952, only for the USSR to match their developments within the same year. A fear of a bomber gap between the two superpowers led to the US matching the development of the USSR’s lithium bomb in 1954. The continuing development in thermonuclear technology shows why the arms race made the world a more dangerous place as both superpowers were determined to overtake the other in terms of having nuclear superiority, thus leading to the superpowers having the capability to use more destructive and powerful atomic weaponry.
Rather, the Chinese alchemists were searching for an elixir of life. In other words, they were combining different chemicals in the hope of unfolding immortality in humans. On the contrary, ancient Chinese alchemists’ mixture of potassium nitrate (saltpetre), charcoal and sulphur was not the elixir of life but the foundation of an explosive powder. By the 12th century the Chinese was able to increase the levels of nitrate within gunpowder to burst cast iron containers alternately creating gunpowder-filled grenade bombs. In early history, gunpowder provided leverage for military conquest.
The terrifying Atomic blasts in the summer of 1945 made way for our current modern age of technology. Having also won the atomic weapons race with Germany, a fair democracy got issue laws on Atomic Warfare. Had a fascist or authoritarian state first discovered nuclear energy and fission, we very possibly could be looking at a much different world today. Positive laws that the U.S government had set on Atomic weaponry can be seen in the Atomic Energy Act of 1946. The Atomic Energy Act stated how the United States government would manage nuclear technology.
History paper #1 Gunpowder also called black powder is considered the earliest explosive invented. The Chinese alchemists of the ninth century were considered to be a major force behind the early development of gunpowder. They first used the substance to treat skin diseases and to kill insects before people realized it would be an advantage to them on the battlefield if used as a weapon. The discover that the substance could be used at battle was found through experimenting. One of the experiments conducted was, attaching bamboo tubes filled with gunpowder, to arrows and launching them with bows.
