His Work and its Significance
• US received news of Nazis building A-bomb
• Establishment of the Manhattan Project in 1942.
• Trinity Test Detonation of first small atomic bomb in 1945.
• Detonation of two large atomic bombs in Japan.
The Significance of his Work
The research conducted in the Manhattan Project resulted in a better understanding of the atom
1. Nuclear Physics and Nuclear Chemistry
2. Nuclear Energy and Nuclear Medicine
3. Modern Stem Cell Research
Cultural impact, significance of work, historical legacy
• Oppenheimer feared for future of the world
• USA planed to make hydrogen bomb –an idea Oppenheimer opposed
• The president approved the hydrogen bomb regardless
• Oppenheimer’s opposition + accusations of communist ties lead to his security clearance being taken away.
• Loss of security clearance meant the loss of influence on science policy
Nuclear Power today:
The first commercial nuclear power stations started operation in the 1950s.
There are over 430 commercial nuclear power reactors operable in 31 countries.
They provide over 11% of the world's electricity as continuous, reliable base-load power, without carbon dioxide emissions.
56 countries operate a total of about 240 research reactors and a further 180 nuclear reactors power some 150 ships and submarines.
The overall presentation will be:
His work and its significance.
The significance of his work in his own time.
The significance of his work today.
The father of the atomic bomb
BEST KNOWN FOR
J. Robert Oppenheimer is often called the "father of the atomic bomb" for leading the Manhattan Project, the program that developed the first nuclear weapon during World War II.
Nuclear energy emerged as the right choice for the UAE because it is a safe, clean and proven technology, it’s commercially viable, and it delivers significant volumes of base-load electricity.
On July 16, 1945, at 5:29:45 AM, a light
"brighter than a thousand suns," filled the valley.
The "Gadget" had a yield equivalent to
19 kilotons of TNT. "Fat Man", the bomb
dropped on Nagasaki was identical in design
to the "Gadget."
We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now, I am become Death, the destroyer of worlds." I suppose we all thought that one way or another.

nuclear stockpiles, facilities, and forces.
The continuing of his work today
In order to produce nuclear weapons, each country must have facilities to produce and refine the nuclear materials, conduct research on weapon design, and store the completed weapons.
