n 1929 Robert Oppenheimer became a professor of physics at the university of california at berkeley and the california institute of technologyh e remained a professor until june 1942 when he became the technical director of the now famous manhattan project, where he oversaw the designing and building of the atomic bomb

Hahn and Strassmann publish paper
describing atomic fission aprocess in which the nucleus of an atom splits into smaller parts and releases a very large amount of energy -
Oppenheimer was appointed the director of the Manhattan Project, a United States executive agency that was responsible for developing the atomic bomb. His first task was to calculate the critical mass of uranium-235
-
-
The Manhattan Project was decided to be stationed in Los Alamos New Mexico the labs would be next to a desert where the scientists could work in privacy and be able to test without danger to anything else with this Oppenheimer and his group of scientists worked to finally come to their first nuclear bomb test
-
if the US would of invaded Japan an estimated one million american casualties. there was a desire to end the war before Russia entered and got land Harry S Truman decided to drop the bomb they selected Hiroshima and Nagasaki because they were previously unbombed and could see the damage they did
-
This was the world's first nuclear bomb test it was saidto have the power of about 20,000 tons of TNT when they saw the mushroom cloud the scientists were very excited and concerned about the huge ammount of destrutive force Here Oppenheimer says, "I am become Death, the destroyer of worlds."

Little Boy was dropped on Hiroshima on August 6th 1945 Hiroshima was mainly a civilian city and didnt contain many military assets It was an uranium bomb 45 thosand dead in inital blast and 140000 dead by december from burns and radiation

Oppenheimer said that his only regret was not making the bomb in time to use it against nazi germany however soon after Oppenheimer said at a meeting of the american philosophical society: “We have made a thing a most terrible weapon that has altered abruptly and profoundly the nature of the world a thing that by all the standards of the world we grew up in is an evil thing and by so doing... we have raised again the question of whether science is good for man.”

the US wanted japan to surrender unconditionally but after the first bomb they hadnt surrendered yet so the US was feeling trigger happy and droped the second on Nagasaki Big man was more explosive Plutonium bomb 64000 dead and Japan surrenders unconditionally the many people didnt think this was necessary

-
Oppenheimer served as director of princeton's institute for advanced study there he stimulated discussion and research on quantum and relativistic physics in the School of natural science
-
After the war, Oppenheimer was appointed Chairman of the General Advisory Committee to the Atomic Energy Commission (AEC), serving from 1947 to 1952. It was in this role that he voiced strong opposition to the development of the hydrogen bomb.
-
he was elected president of the american physical society the highest honor physicists can give a colleague during this time his research involved the theory of fundamental particles and mesons
-
Oppenheimer was appointed as chairman of the general advisory committee of the atomic energy commission he was now fully aware of the dangers of radioactivity caused by nuclear explosions he opposed the development of the hydrogen bomb Oppenheimer regarded it as a genocidal weapon and he argued that its only purpose would be the destruction of civilian populations in the tens or hundreds of millions which caused him to loose his secrity clearance
-
Oppenheimer was a victim of mccarthyism in 1953 he was accused of being closely associated with communists in the 1930s and 1940s this included his relationship with jean tatlock and his wife a security hearing decided he was not guilty but said that he should not have access to military secrets As a result he was removed from the atomic energy commission. This created great controversy and 493 scientists who worked on the manhattan project with him signed a protests against it
-
in 1953 the Atomic energy commission suspended his access to "classified" information because his strong resistance to building a hydrogen bomb because he saw it as a weapon of genocide
-
the Atomic Energy Commission recognized Oppenheimer's role in the development of atomic research and awarded him the prestigious Enrico Fermi Award, an award honoring scientists of international stature for their lifetime achievement in the development, use, or production of energy. It is administered by the U.S. government's Department of Energy.
