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.

How did the atomic bomb help the Americans in World War 2?
The atomic bombs saved the Americans casualties, from having to invade mainland Japan, ranging from 300,000 to 750,000. The estimates vary by different report estimates. Even the 300,000 estimate from the most generouos report would have been catastrophic. By 1944, the US Army was stripping its rear area units for infantry replacements.
Where did the US drop the atomic bomb in ww1?
It didn't. Wrong war. It wasn't invented until WWII.
In WW2 however the atomic bomb was dropped on two cities from japan; first on Hiroshima, then a second dropped on Nagasaki when japan didn't surrender after the first atomic bomb.
Japan was given no opportunity to surrender after the first atomic bomb. Truman's order to use the atomic bomb authorized use as they became available. The only reason Japan had a chance to surrender after the second and before the third atomic bomb was the third was still being prepared and crated for shipment at Los Alamos. Had Japan not surrendered the third atomic bomb would have left San Francisco on a B-29 on August 18 and probably been dropped between August 25 to August 28.
There were another 20 more atomic bombs scheduled for production & delivery on Japan from September through December of 1945.
Who invented the atomic bombs Fatman and Little Boy?
There was no single inventor of the Little Boy gun bomb method, as that method was an obvious means of assembling a supercritical mass.
Seth Neddermeyer was the inventor of the implosion method for the Fatman to assemble a supercritical mass fast enough to prevent a fizzle when using reactor produced plutonium. However he was unable to make it work and George Kistiakowsky was called in. George Kistiakowsky invented the actual shaped charge explosive lense system that was used in both the Gadget and the Fatman.
What country developed its own atomic bomb in 1949?
The Soviet Union developed its own atomic bomb in 1949. This achievement marked a significant milestone in the Cold War, as it ended the United States' post-World War II monopoly on nuclear weapons. The Soviet bomb, known as "First Lightning" or "Joe 1," was successfully tested on August 29, 1949, escalating tensions between the two superpowers.
What island were the 2 atomic bombs dropped on in ww2?
It wasn't an island, it is a country. The country was Japan.
What was the most dramatic spy case involving an atomic bomb?
Everyone thinks it was the Rosenbergs, but it was actually Ted Hall.
How many atomic bombs are made a year?
At this time (2012) neither the US or Russia makes any. Other countries may be making small numbers.
What was the atomic bomb invented for?
Leo Szilard invented the atomic bomb & reactor in 1933 as an improved means of transmuting elements. His 1934 patent on this invention also made claims for use in explosives or power generation.
What german inventor invented the atomic bomb?
No german, the inventor of the atom bomb was a hungarian.
Why shouldn't we used the atomic bomb during World War 2?
The Japanese were defeated on a island and 1000's of planes were fire bombing their cities to ruin so there was no need to use the A bomb
Which country dropped the atomic bomb in the cold war?
No nation dropped an atomic weapon during the cold war. The cold war is not the same as World War 2. Two atomic bombs were dropped on Japan by the US at the end of World War 2. The cold war is called 'cold' because it was not an actual armed conflict. It was a period marked by a conflict of ideologies, propaganda and fear.
The atomic bomb was invented by who in the 1950s?
The atomic bomb was invented in 1933 (by Leo Szilard) and finally built in 1945 (by the US Manhattan Project, which involved hundreds of thousands of people). It was duplicated in 1949 (by the USSR, assisted by information from spies in the US project).
It was already in "mass production" by both the US and USSR by the early 1950s , thus not invented by anyone in the 1950s.
Leo Szilard, a Hungarian Jew living in London at the time, in 1933. He patented it in 1934, the patent GB630726 was granted in 1936 and immediately classified to prevent Nazi Germany from using it. It took 12 more years before the US was able to build the first ones, after an enormous investment in industrial infrastructure. Szilard's patent was not made public until 1949. During WW2 this was done under the Manhattan Project. There was a large team of scientists, the chief one was Dr Robert Oppenheimer.
Professor Rudolph Peierls and Otto Frisch were also involved.
The atomic bomb was originally invented in 1940 by German scientists, Professor Rudolph Peierls and Otto Frisch who were both working for Britain at the time.
During World War II, the United States, with the assistance (collaboration) of physicists, mathematicians, and engineers from the U.S., Britain, Canada and Europe, completed the Manhattan Project to produce the first atomic bomb.
(The project started as the "Manhattan District Engineers" and only became "The Manhattan Project" some time later).
There was some early speculation about the possibility of what could be done if a nuclear chain reaction was unleashed in a way that would allow it to build without control. For a roll call, consider that Robert Oppenheimer was the head of "science" for the Manhattan Project, and (in alphabetical order) Felix Block, David Bohm, Niels Bohr, Enrico Fermi, James Franck, Otto Frisch, Klaus Fuchs, Rudolf Peierls, Emilio Segre, Leo Szilard, Edward Teller and Eugene Wigner all played crucial roles in getting the weapon designed and built.
The physicist Albert Einstein did not participate directly in the invention of the atomic bomb-but was instrumental in facilitating its development. His Special Theory of Relativity emphasized that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this principle.
The first demonstration of "the gadget" (the code name for the first atomic bomb) was at Trinity site in Alamogordo, New Mexico, and it proved that the weapon would detonate and that the chain would build as predicted. The second and third demonstrations were conducted in Japan, which brought a quick end to the Second World War. Just up to and during World War 2, Germany was also working to develop atomic weapons, but was hampered by many technical and political problems (including sabotage and Allied bombings) which prevented their successfully completing their work. This left the U.S. as the only nation to ever unleash nuclear weapons in an attack.
The first fission weapons, also known as "atomic bombs," were developed jointly by the United States, Britain and Canada during World War II in what was called the Manhattan Project. (Wikipedia)
Leo Szilard invented the atomic bomb in 1933 while crossing a London street. He patented it in 1934. (British patent 630,726)
The Manhattan Project built the first one in 1945.

the united states made the atomic bomb
Should the atomic bomb be used?
no because it killed to many innocent people in japan and the radiation waves never go away
the full range of an atomic bomb (not just blast range)
is 20 square miles
How did scientists feel for creating atomic bomb?
Many scientists involved in the creation of the atomic bomb felt a sense of responsibility and moral dilemma. Some expressed regret and guilt later, as they understood the devastating consequences of the bomb on innocent civilians in Hiroshima and Nagasaki. Others viewed it as a necessary evil to end the war and prevent further loss of life.
What did the atomic bomb do to the land of Hiroshima?
half of the city vanished. According to U.S. estimates, 60,000 to 70,000 people were killed or missing, 140,000 were injuried many more were made homeless as a result of the bomb. Deadly radiation reached over 100,000. In the blast, thousands died instantly.
The city was unbelievably devastated. Of its 90,000 buildings, over 60,000 were demolished.
If the atomic bomb cost billions of dollars why did you build one?
The original reason that the US began the project to build the atomic bomb was fear. Fear that Nazi Germany would build one first and use it to take over the world.
After the war ended the US and USSR built them out of fear of each other.
How was the atomic bomb detonated?
With conventional explosives to assemble a supercritical mass before it can begin a spontaneous chain reaction, melt and fizzle. Then a neutron source sprays the supercritical mass with a burst of neutrons at the optimal time to trigger a high efficiency chain reaction. The conventional explosives were detonated with electrical exploding wire detonators.
Which atomic bomb used uranium and which used plutonium?
Hiroshima bomb: uranium
Nagasaki bomb: plutonium
Did World War 2 first start using atomic bombs?
No, it started formally when Hitler ordered a faked Polish attack (by German soldiers wearing Polish uniforms) on a German radio station on September 1, 1939 (although fighting had been going on for several years before that between Italy & Ethiopia and Japan & China). In "retaliation" for this faked attack, Hitler declared war on Poland and invaded.
The war was ended by the first use of atomic bombs ever in combat when two bombs were dropped on Japanese cities: Hiroshima on August 6, 1945 & Nagasaki on August 9, 1945.
