Later on, more liberal government policies were put into place; daimyo and officials were encouraged to take more ronin into their service as samurai.

The atomic bomb was not invented by any country, it was  invented in 1933 by Leo Szilard (he was in London at the time, so  when he patented the invention he sold it to the â¦ British Admiralty  who classified it to keep the idea away from the Nazis).
The history of the atomic bomb began with the Manhattan Project. It was tasked to create the bomb beginning in 1939. The scientists who invented the bomb included Robert Oppenheimer, Edward Teller, Rudolf Peierls and many others.wo miles away there was also heavy damage. On August 9, 1945 another atomic bomb (plutonium type) was dropped in Nagasaki. Over 25,000 people were killed in an instant. Despite this fact, the two bombs actually used less than a tenth of 1 percent of their power.
