Assignment # 7

**What was the significance for the way we live now (for technological or scientific advances) based on the contribution or discoveries of your chosen scientist? What does the life story or biography of this scientist teach us today about what it takes to do successful science? (What challenges or obstacles did this scientist have to overcome?What does his or her struggle teach us today? Were the achievements of this scientist recognized in his or her lifetime? If not, why not? Did this scientist’s work inspire us, give us a sense of wonder, threaten us or does it give us some combination of these ideas?

Answer-

Did he have doubts regarding the effects on the nuclear bomb? Did he even have an iota of guilt? Even if he did write against it in 1946, the deed was done and thousands of people and their generations to come had become its victims. This story of the life of Robert Oppenheimer serves as a lesson to the present day students and   scientists. It warns them against the excessive use of weaponry and its ill effects.

In 1941 Oppenheimer was assigned the atomic bomb project. His first task was to calculate the critical mass of uranium-235, i.e. the amount of uranium needed to sustain a chain reaction. He continued his research and succeeded. The atomic bomb was finally dropped on cities in Japan with a far reaching and extremely negative outcome.

When the war ended, Robert Oppenheimer came to be known as the as the "father of the A-bomb,” He said, "the physicists have known sin, and this is a knowledge which they cannot lose", revealing his guilt. His political past and his caution on the hydrogen bomb finally had terrible results on his career. In 1953, the Atomic Energy Commission suspended his security clearance.

The work of this scientist inspires us for his intelligence and we wonder whether his obnoxiously violent invention was really worth it? However, this is threatening weapon to innocent public by terrorist or by countries enemy. This shouldn’t be happening. This weapons and bombs create a lot of trouble. In my opinion, I don’t think, nuclear weapons and ak-47 guns should be built by scientist anymore and stop making new inventions on this. People don’t need any weapons anymore. People need to live in peace onwards.
