It didn't really. The war was all but over when Hiroshima and Nagasaki were bombed. It did ensure the Japanese surrendered earlier then they may have otherwise done. There were claims made that doing so saved many lives. Many people did not believe that at the time and more do not believe it today.
The west knew that the USSR would be its main rival after the war and by showing that the west, the US in particular, had 'the bomb' was a demonstration to the USSR who had not yet developed the weapon.
No bomb ended WWII.
The use of the two atomic (Little Boy and Fat Boy) weapons on Japan effectively caused the surrender of the Japanese.
it was called the "fatman" atomic bomb
It made Japan to surrender.
Hiroshima and Nagasaki
None whatsoever, the Manhattan Project was a closely guarded secret.
The inside of an atom bomb is not the same as the inside of a baseball, but the fissile material (enriched uranium/plutonium) contained in an atom bomb could be about the same size as a baseball. The material is surrounded by shaped explosives, detonators, control circuits and a suitable casing. If a baseball was the same as an atomic bomb, nobody would play the game due to an unacceptable risk of vapourisation or radiation poisoning.
The radiation levels of atomic bombs vary according to the amount of radioactive elements put into the bombs or missiles and if they are actually used. Once the radioactive matter is inside the bomb housing the radiation levels are negligible but once one of the nuclear bombs is used then the variables come into play. (see related link below to see how complex it is) Consider this: the atomic bombs dropped on Japan in 1945 are 1/10th the killing power of today's nuclear missiles. If one modern nuclear missile were to be used today the bomb would be able to kill about a third of the world with the initial bomb blast and radiation fallout. The radiation level after Hiroshima and Nagasaki was not really measured until after the US occupied Japan. The Japanese leaders did not really understand the radiation fallout and poisonous danger and they did not use radiation detectors right after the blast. It is rumored the radiation levels were 100 times today's acceptable levels of radiation.
The new weapons technology caused more destruction and casualties as well as ending trench warfare.
Oak Ridge Tennessee was developed from the ground up for the purpose of building the atom bomb components. They city grew to 75 thousand and became the 5th largest city in Tennessee. The city is still there. They built huge manufacturing facilities there. The atom bombs dropped on Japan motivated Emperor Hirohito to surrender.
After the atomic bombs Japan had no other choice.
None whatsoever, the Manhattan Project was a closely guarded secret.
because They felt doin what they do
It is the other way around, the use of the atomic bomb played a role in the weapons race.
none
Relativity and the Atomic bomb
No atomic bombs were used in the Korean War and there were never any plans to use them. Possibly the existence of atomic weapons had some small effect.
Hiroshima played a part in WWII basically by revenge for the bombing of pearl harbor. however it was also planned for the US to end the war by using the bomb, however, they had to use another atomic bomb on Nagasaki to truly end it.
Albert Einstein did not make the atomic bomb. Einstein himself did not even play a role in the development of the atomic bomb other than signing the letter to get Roosevelt to approve the making of it. He did help the United States Navy with some unrelated theoretical questions it was working on during the war. And girls wouldn't be smart enough. JK. But not really. Ok really.
He helped create the nuclear bomb to bomb Hiroshima.
Science played a major role in World War II. Science's atom-bomb which was made form Einstein's E=M squared. Science crated the first atomic bomb which made Japan surrender which was called V-J day. (V-J day stands for Victory in Japan day.
The world is ending.
