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).
In 1938 many people feared that Hitler would build an atomic bomb after word spread that German scientist had split the uranium atom (fission). However, one of Hitlers mistakes was his persecution of Jewish scientists.This persecution resulted in numerous scientists seeking asylum in the United States.n 1945 the United States covert operation known as The Manhattan Project achieved its goal-to create the first atomic bomb. Since its inception in 1939, scientist had struggled to find a way to harness the power of fission.
