Later on, more liberal government policies were put into place; daimyo and officials were encouraged to take more ronin into their service as samurai. However, this option only could serve a minority of ronin; in an era of peace, few clans needed the large number of samurai that they would need in times of war.
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).
You probably know Little Boy and Fat Man as the atomic bombs detonated over Hiroshima and Nagasaki, effectively ending WWII. The U.S. rushed headlong into the development of the bombs, trying to actualize the atomic bomb ahead of the Nazis. And we did it.But during the Manhattan Project scientists developed at least four bombsâThin Man, The Gadget, Little Boy and Fat Manâthree of which made it to fruition (The Gadget, Little Boy, and Fat Man) with two actually being used in war (Little Boy and Fat Man).ess than three weeks after the Trinity Test, Little Boy was successfully detonated over Hiroshima on August 6, 1945. Three days later, Fat Man was detonated over Nagasaki, adding atomic weapons to mankindâs arsenal for the first time.
