I will mainly be focusing on the bombing of Hiroshima and Nagasaki, the build up to these chilling events , and some information about nuclear weapons in the world today.
The test was first set for 3 days earlier, but it had been delayed due to thunderstorms The trinity bomb as it is now called let off an explosion which was almost four times larger then what was predicted by the close to 200 scientist working on the project. .
The development of The nuclear bomb started In 1939 when, physicists in the United States had learned of experiments in Germany demonstrating the possibility of Nuclear fission and had understood that the potential energy might be released in an extremely powerful, and explosive weapon of unprecedented power. On Aug. 2, 1939, Albert Einstein Presented the military potential of an uncontrolled fission chain reaction to President Franklin D. Roosevelt, and warned him the danger of Nazi Germany's forestalling other states in the development of an atomic bomb. Eventually, the U.S. Office of Scientific Research and Development was created in June 1941 and given joint responsibility with the war department in the Manhattan Project to develop a nuclear bomb. .
Since 1945, the United States has manufactured and deployed more than 70,000 nuclear weapons, supposedly to deter and if necessary fight a nuclear war. Some observers believe the absence of a third world war confirms that these weapons were a prudent and cost-effective response to the uncertainty and fear surrounding the Soviet Union's military and political ambitions during the cold war. However At one point in the early 1960s, the Secretary of Defense for the United States Robert McNamara estimated that the United States needed about 400 megatons' worth of nuclear explosives to be able to destroy its adversaries, and something like 1000 long-range weapons could get the job done. At the time, the US nuclear stockpile contained 17,000 megatons of nuclear explosives.
