Atomic Bombs

The cities were called Hiroshima and Nagasaki. The US dropped the atomic bombs onto Japan on August 6th and 9th 1945.

It's hard to say exactly. There were many people who helped. There were 18,000 at Los Alamos and probably 50,000 or more in Hanford, WA and 45,000 at Oak Ridge, TN. There were probably 50,000 more in various smaller groups.

Neither he nor the builders knew what the "physical" after effects of the explosion might include.

However, Truman may have had several motivations for its use as a weapon. The first was obviously to coerce the surrender of Japan. But he also may have hoped to dissuade the Soviet Union from trying to exploit the war to gain territorial concessions. A successful atomic weapon might also extend US foreign power without the need for massive conventional military forces. And to some extent, it did.

Neurofibromatiosis is a genetics disease. Its passed through the parents genes, and it affects the brain, spinal cord, nerves, and skin.

The Enola Gay is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second - and last - nuclear attack in history.

The project was codenamed "The Manhattan Project" in the United States under the Truman administration.

The strong nuclear force.

well most of them would have died, but the survivors where traumatised by the experience. most of the survivors also have to clear and dispose of the remaining bodies..

He stated that he wanted to end the war and collapse Japan's means to make war.

Plants do grow where Hiroshima was bombed. In fact they began rebuilding the city in 1946. It is a very beautiful city. There are beautiful pictures on the web of the city.

According to the series Island, it was hidden on an island in the Pacific. There is no credible factual evidence for this claim; the bomb and the island both appear to be fictional.

The cost in lives of the US military in the invasion of the Japanese mainland.

Yes, they were aware that their action would shorten the war and save Allied lives in the long run.

There were a few other options that Truman could have used instead of the destructive force that is the atom bomb. The US troops had been island hopping and were ready to begin an invasion. The con of this plan would be the heavy loss of American soldiers and that is probably the main factor as to why Truman didn't use it. Another option would be to negotiate with the Japanese and maybe come to an agreement. This was also pushed out because of the fact that the Japanese were ruthless fighters and would not go down easily in any battle. The option that would have been the best in my opinion would be to gain the help of the Soviet Union. On August 8, 1945, a day before the second atomic bomb was dropped, the Soviet's declared war on Japan which is believed to be the reason why they unconditionally surrendered. This plan would have taken less lives and done less damage to Japan and therefore would have been the better idea.

A quotation of Lord Krishna in the Hindu Bhagavad Gita: "I am become death. The destroyer of worlds.".

Harry Truman dropped the bombs on Nagasaki and Hiroshima to end the war. At the time you could say that America was fighting two wars, one against Germany and one against Japan. Even though Japanese military supplies were very limited at this point in time of the war, Truman still enforced the Japanese to sign a treaty to surrender. After they failed to surrendered, America dropped 2 bombs on Japan. The effect was Japan surrendered the war immediately after the 2nd bombing. It also showed the military power America could potentially use to the world. The significance of it now is that the atomic bomb has basically created an arms race. The Cold War was a fued over not only communism but the fear of a nuclear war. Since the mid 1970's America has tried to use a system of detente, in which they make peaceful agreements with other nations such as China and Russia for disarmament. I guess you could say that the atomic bomb unleashed mankind with the ability to destroy anything in its path, and now that its more aware we are trying to prevent nuclear build ups.

To defend against a possible Nazi atomic bomb!

"What our government should do," it read in part, "is to make our responsibility for the war clear, and apologize and compensate those victims of the war inside and outside Japan."

It was dropped by a B-29 bomber.

The first Atom Bomb dropped on Hiroshima was called "Little Boy". It weighted about 9,700 pounds and used about 141 pounds of Uranium-235 to generate an explosive blast roughly equal to about 15,000 tons (or 30 million pounds) of conventional TNT explosive.

The second Atom Bomb dropped was on Nagasaki. It was called "Fat Man". It weighed about 10,300 pounds and used about 14 pounds of Plutonium-239 & 240 to generate an explosive blast roughly equal to about 21,000 tons (or 42 million pounds) of conventional TNT explosive.

Black rain spreads the radiation after an atomic bomb. The mushroom cloud puts radiation in the atmosphere, which becomes the black rain. Black rain is the main cause for widspread cancers and other sicknesses after an atomic bomb.

Uranium-235 (not uranium-238) is used in atomic bombs; under nuclear fission with neutrons uranium release an enormous quantity of energy (202,5 MeV per one atom of 235U).

In the Manhattan Project they worked on two different designs for nuclear weapons. The idea is to make a critical mass which causes a chain reaction. You do this by compressing the material violently with conventional explosives. The Little Boy used an internal cannon to shoot a projectile into a mass of uranium to compress it. The Fat Man used a sphere of plutonium surrounded by a 'shape charge' that would explode and compress it.
