Atomic Bombs

1949, it was a clone of the US Fatman design based on stolen plans.

I am a survivor of atomic testing in 1954 in the southwest United States. I was born on Aug 18, 1954 in Downey, California and according to my mother(deceased), I was born with a tan and platinum hair and burns from the waste to the knees and had to be treated with Vaseline and baby powder for an entire year after my birth. She said that , that day the winds carried fallout dust into the maternity ward affecting the babies that day. So I would assume there are more of us if they are still alive.

Shortly after President Roosevelt (FDR) passed away, Truman came into office and made this decision.

Too many to list by name (including my grandfather, who worked at the Hanford Site oiling machines from the summer of 1944 through February 1945, without ever having any idea of what the purpose of Hanford was or that its product was part of a very powerful bomb).

At the end of World War II, few questioned Truman's decision to drop the atomic bombs on Hiroshima and Nagasaki. Most Americans accepted the obvious reasoning: the atomic bombings brought the war to a more timely end. They did not have a problem with over one hundred thousand of the enemy being killed. After all, the Japanese attacked America, and not the other way around. In later years, however, many have begun to question the conventional wisdom of "Truman was saving lives," putting forth theories of their own. However, when one examines the issue with great attention to the results of the atomic bombings and compares these results with possible alternatives to using said bombs, the line between truth and fiction begins to clear. Truman's decision to use the atomic bomb on Japan was for the purpose of saving lives and ending the war quickly in order to prevent a disastrous land invasion.

To make a fission atomic bomb you just take either uranium or plutonium, which are fast-fission materials and find a way to smash the soul out of them so they can make neutrons to continue the chain reaction. You either just take some fissionable uranium, make a bullet out of one and a ball of the other, build a cannon-shaped bomb that shoots the bullet of uranium into the ball of uranium at the end of the barrel - and boom.

To make the second kind, you need some plutonium. Plutonium is easy to obtain but it is extremely hard to make into a bomb, because if you shoot two masses of plutonium together like the uranium bomb style, they fission so much easier that they start reacting before they touch and blow themselves apart before anything can fission, so you will need to make a ball of plutonium crush in itself using a shock wave made by a explosion. You surround a ball of fissionable plutonium with explosive stuff. When the surrounding explosives goes boom, the shock waves made by the explosives hits the ball. This causes the plutonium to supercompress itself together - and boom.

the Nazi didn't build the atomic bomb the Americans did....

The B-29. In WW2 there were only 2 planes available with the capacity to carry a bomb the size and weight of the atomic bombs: the american B-29 and the british Lancaster. But since the bomb was american, the plane had to be american. The Lancaster might have been a better choice as it had a longer bomb-bay, permitting a more stable tail fin design, but the B-29 was american.

An A-bomb is the short form of atomic bomb, e.g. a nuclear bomb.

Nuclear. The weapon is uranium, and the chain reaction caused by a single split will turn the whole thing to energy.

E=mc^2 shows that the explosion will produce energy equivalent to the mass of the uranium, multiplied by the speed of light squared.

1. H. G. Wells used the words "atomic bomb" in his 1914 novel The World Set Free.
2. Leo Szilard filed the first atomic bomb related patent in 1934, on the neutron chain reaction.
3. A joint German and Swedish team discovered nuclear fission in uranium-235 in 1939.
4. The US Manhattan Project developed the infrastructure to build atomic bombs, beginning production in 1945. This project employed tens of thousands of workers.

No one made an atom bomb in World war 1. It took to the very end of World war 2 for the Atomic bomb to be invented. Exactly who invented is is a bit tricky. There were several different scientists that had come up with the idea separately. But the man mostly associated with turning it into a working weapon is Dr Robert Oppenheimer.

World War II

Just before sunrise (while still dark) on July 16, 1945.

No. How could he die creating a thing he did not create? His one an only connection to the creation of atomic bombs was to put his signature on a letter to FDR warning that the Nazis might be trying to make atomic bombs. He did not even write this letter, Leo Szilard (the inventor of the atomic bomb in 1933) wrote it.

Leo Szilard invented the atomic bomb in 1933 while studying possible ways to more effectively perform atomic transmutation experiments with neutrons, that he was working on at the tim in London.

The soviet Union started its program after learning of America's efforts to make the atomic bomb. it was tested on August 29th 1949. The test is known to American's as Joe 1

I suggest reading Richard Rhodes book: The Making of the Atomic Bomb.

Can't answer question as I can't tell what it is asking. It is probably a very good question you meant to ask, but something was lost in the typing.

The first atomic bomb detonated was the Trinity Test Bomb on July 16, 1945.

It had the estimated explosive power eqivalent of 20,000 Tons of TNT.

It was identical to the bomb dropped on Nagasaki 3 weeks later.

The Hiroshima bomb was of a different design and was about 15,000 Tons equvalent.
