Atomic Bombs
Atomic bomb is an explosive device in which a large amount of energy is released through nuclear reactions. This makes an atomic bomb, more properly called a nuclear weapon, a much more powerful device than any conventional bomb containing chemical explosives. The first Atomic Bombs were used during World War 2 in 1945 by the US onto 2 Japanese cities.

Who ordered the use of atomic bombs on two Japanese cities?
the president during that moment of history
Who believed the use of the atomic bomb was necessary?
The use of the bomb was necessary. Japan was getting overconfident in their abilities after the bombing of Pearl Harbor. If Truman did not drop the atomic bomb, many more people would have been killed as a result of the ensuing battle. I do believe that the effects of the atomic bomb on human lives and the fallout mean that the atomic bomb should only ever be used in the most dire of circumstances to save more lives than it ends.
Hope this helps,

Was the atomic bomb a necessary evil?
yes. an invasion of japan would have costed about 1 million american/allied lives.
What events happened in the 1970 - through 1979?
everyone died because of the atomic bomb and nuclear bomb
Why did the US two atomic bombs on japan?
It was near the end of World War 2, and Japan wouldn't surrender with no terms to the US, so President Harry S Truman gave the order to drop 2 atomic bombs on Japan. One oh Hiroshima, the other on Nagasaki.
Japan surrendered then.
Who wrote President Roosevelt in 1939 proposing the feasibility of an atomic bomb?
It was mainly Albert Einstein.
Who named the trinity project used in the first atomic bombs?
The United States' effort to develop a nuclear weapon came during World War II in response to the potential threat of a German nuclear weapon. On 6 December 1941, President Roosevelt appointed a committee to determine if the United States could construct a nuclear weapon. Six months later, the committee gave the President its report, recommending a fast-paced program that would cost up to $100 million and that might produce the weapon by July 1944 (1: 12,13).
The President accepted the committee's recommendation. The effort to construct the weapon was turned over to the War Department, which assigned the task to the Army Corps of Engineers. In September 1942, the Corps of Engineers established the Manhattan Engineer District (MED), under the command of Major General Leslie Groves, to oversee the development of a nuclear weapon. This effort was code named the "Manhattan Project" (1: 13).
During the first 2 years of the Manhattan Project, work proceeded at a slow but steady pace. Significant technical problems had to be solved, and difficulties in the concentration of uranium-235 and production of plutonium, particularly the inability to process large amounts, often frustrated the scientists. Nonetheless, by 1944 sufficient progress had been made to persuade the scientists that their efforts might succeed. A test of the plutonium implosion device was necessary to determine if it would work and what its effects would be. Led by Dr. J. Robert Oppenheimer, Manhattan Project scientists at Los Alamos Laboratory (later to become the Los Alamos National Laboratory) were "to make preparations for a field test in which blast, earth shock, neutron and gamma radiation would be studied and complete photographic records made of the explosion and any atmospheric phenomena connected with the explosion"
Truman's number one motivation: 200,000 estimated deaths from the atomic bombs and see the surrender of the Japanese happen Versus sending millions of American and Russian Allies into Japan to kill millions of Japanese military and civilian people. He chose the first hoping it would end the war and save millions of lives, which it did.
Who thought of the atomic bombs that were dropped on Japan?
J. Robert Oppenheimer was in charge of the Manhattan Project, which was started by Franklin Delano Roosevelt. The Manhattan Project produced both atomic bombs.
How many years did it take to build an atomic bomb?
It takes very little time to build an atomic bomb, once a country has the necessary industrial infrastructure to produce the fissile material.
How is the explosion of an atomic bomb different from the explosion of dynamite?
It's more energy from less mass. There's about 10 million times more energy from the amount of plutonium in the fission reaction of an A-bomb than there is in the chemical reaction from the same amount of dynamite by weight.
On the flip side, the fission reaction requires hundreds, or thousands of times more raw material(explosive "lenses" for implosion to critical mass, bomb casing ect.) A small bundle of dynamite requires only a blasting cap. Moreover, more of the dynamite is involved in the reaction. All that considered, a nuke weapon is still far more powerful in proportion to mass than a whole bunch of dynamite. "Shrimp" the 1st solid fuel hydrogen bomb ever detonated(& the most powerful explosion set of by the US), in a shot called Castle Bravo, detonated w/ a power of 15 megatons(30 billion#) of tnt, which is slightly less potent that dynamite. The whole device weighed about 23,000#, including the casing & everything required to make it go boom. So the entire device was almost 1.4 million times more powerful than the same mass of conventional explosive.
How has the atomic bomb evolved over time?
They have been reduced in physical size, increased in yield, made more durable and secure.
Leo Szilard invented the atomic bomb in 1933 in London and patented it in 1934. No materials were known at the time to make it work however.
In 1938 Otto Frisch in Germany discovered that Uranium-235 would fission. This was the missing ingredient to Szilard's invention.
However It was not until 1945 that the Manhattan Project was actually able to build one. This took thousands of workers.
Who is referred to as father of the atomic bomb?
The scientist given the most credit for the building of the atomic bomb is Robert Oppenheimer.
What was the name of the plane that dropped the first atomic bomb in World War 2?
The Enola Gay dropped the first atomic bomb, on Hiroshima on August 6, 1945.
The bomber named Bockscar dropped the second bomb, on Nagasaki on August 9. Both aircraft were B-29 bombers that operated from a special unit; the 509th Composite Bomb Group, flying from Tinian Island in the Marianas.
Who supported the atomic bomb?
only USA knew of the bomb, The first confirmation of exactly what had happened came sixteen hours later with the announcement of the bombing by the USA
Why is the atomic bomb different from normal bombs?
- conventional chemical bombs get their energy from the electromagnetic force of the 8 valence band electrons of the outermost S & P orbitals
- nuclear bombs get their energy from the strong nuclear force that holds the nucleus of the atom together
Note: both operate in accordance with E=Mc2, but as the strong force is several orders of magnitude stronger than the electromagnetic force several orders of magnitude more mass converts to energy in nuclear bombs than in conventional bombs.
