H. G. Wells' novel The World Set Free published in 1914 was the first usage of the term atomic bomb. He reasonably correctly estimated their energy release (based on Einstein's special relativity) but could not imagine that the energy could be released faster than was possible in chemical bombs, so his atomic bomb explosions took days to weeks instead of microseconds.
Leo Szilard invented the neutron chain reaction, which makes both atomic bombs and nuclear reactors possible in 1933 while living in London. He patented it in 1934 and when the patent (GB630726) was granted in 1936 he sold it to the British Admiralty who classified it to keep the information from the Nazis. The only problem was that no material was known at that time that would support a neutron chain reaction.
In 1939 a joint German and Swedish team in repeating an experiment performed originally in 1938 by Enrico Fermi (who had mistakenly decided that when he bombarded uranium with neutrons that he had made transuranic elements) determined that neutrons split the uranium atom into two smaller intensely radioactive atoms plus several neutrons. It was not necessary to see Szilard's classified patent to realize that uranium was the material that would support a neutron chain reaction. It took a little more research to identify that only the rare uranium-235 isotope (0.7%) would support a neutron chain reaction, not the plentiful uranium-238 isotope (99.3%).
The British did not declassify Szilard's patent until 1949, after the Soviet atomic bomb test.
No president invented any nuclear bomb.
Leo Szilard invented the fission bomb. Edward Teller invented the fusion bomb. Both were from Hungary.
he invented it with metal
They invented the nuclear bomb to be the ultimate weapon of mass destruction. It was invented by a group of scientists. This group, ironically, included Einstein until he died and was replaced.
There were no nuclear weapons in WW1. The nuclear bomb was not invented until WW2.
None. The fission bomb was invented in 1933 by the physicist Leo Szilard. The staged fusion bomb was invented in 1949 by the mathematician Stan Ulam and the physicist Edward Teller.
Yes he was.
No, it was invented in London in 1933 and built in Los Alamos, NM in 1945.
No the hydrogen bomb is -The hydrogen bomb is a type of nuclear bomb.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
the hydrogen bomb, is a nuclear bomb
During world war 2, the United States finished making them. They were first to have a nuclear bomb and the only ones to use it againts mankind.
Originally as a defense against the possibility of Nazi Germany making it.
Read Richard Rhodes book : The Making of the Atomic Bomb.
After USSR (mostly in asia), China.
He invented the first nuclear weapon, the atomic bomb.
Both. An atomic bomb IS a nuclear bomb.
A hydrogen bomb is, by far, the most destructive weapon that mankind has ever invented. It is the most powerful type of nuclear bomb.
A bomb can be either conventional or nuclear.
the Vagina (nuclear bomb) will expand
The first atomic bomb was developed during a top secret project in Word War II called "Manhattan".
Read Richard Rhodes book "The Making of the Atomic Bomb", the definitive publicly available work on the subject.
