Ahead of the release of Christopher Nolan ’s long - awaitedOppenheimer(and Lin Manuel - Miranda ’s even more anticipatedHip Hoppenheimer ) this week there has been a reincarnate pastime in its cardinal character , the existent - life J. Robert Oppenheimer .

Oppenheimer was the theoretical physicist often referred to as the " father of the atomic bomb " for his work as theatre director of the Manhattan Project ’s Los Alamos Laboratory in New Mexico . The project was a winner , and onJuly 16 , 1945 , Oppenheimer and others involve in the project watched as the first atomic explosion took blank space .

Two nuclear bombs were later drop on Japan , kill hundred of K of citizens and ending World War II . Others on the project free their part in this way .

“ The atomic bombing of Hiroshima and Nagasaki ended World War II . There can be no incertitude of that , " Lieutenant General Leslie R Groves , former theatre director of the Manhattan Project set to be portrayed by Matt Damon in the movie , saidyears later . " While they brought death and wipeout on a horrifying scale , they forfend even greater losses – American , English , and Japanese . ”

Oppenheimer , with more responsibility than most on the project , was aware of the weight of that decision . In a famous audience for a documentary film title " The Decision to Drop the Bomb " , he said that as he watched the explosion he was remind of a passage from theBhagavadgita .

" We knew the world would not be the same . A few masses laughed . A few people cried . Most the great unwashed were silent , " Oppenheimer said . " I remember the line from the Hindu Christian Bible , the Bhagavadgita . Vishnu is attempt to carry the Prince that he should do his duty and to impress him takes on his multi - armed form and say , ' now , I am become Death , the destroyer of worlds . ' I guess we all thought that one way or another . "

Oppenheimer apparently felt a terrible amount of guilt about the creation of nuclear weapons following the destruction of Hiroshima and Nagasaki , tellingPresident Truman"I feel I have descent on my hands " .

" If atomic bomb are to be impart as new artillery to the arsenals of a warring world , or to the armory of the nations preparing for warfare , then the fourth dimension will come when world will curse the epithet of Los Alamos and Hiroshima , " hesaid in 1945 . " The people of this world must join or they will perish . This warfare that has ravaged so much of the dry land , has written these words . The atomic bomb calorimeter has spell them out for all men to infer . "

He went on toopposethe US Government ’s architectural plan to expand its nuclear arsenal with more muscular H bombs , just a few years after the war . But it was too recent . The djinni , as they say , was out of the bottleful .
