The last section about Oppenheimer is in error. The Trinity test of a nuclear weapon was not a hydrogen bomb. A hydrogen bomb uses a Fission (atomic splitting of uranium or plutonium) to get enough temperature to start fusion of hydrogen atoms. The Trinity est was just fission (splitting) of uranium atoms. The 18,000 tons (18 kilotons) of TNT is very small by nuclear warhead standards. A hydrogen bomb can be in the Megatons range.
One of the great features of FR.....experts on every subject.
The bomb tested at Trinity was a plutonium bomb.
