Frisch-Peierls said that a bomb could be made out of uranium. We know this is true because of the bombs dropped on Hiroshima and Nagasaki. One thing I found interesting is that he said that “i n any case, no arrangement containing hydrogen and based on the action of slow neutrons could act as an effective super-bomb, because the reaction would be too slow.  “ This is interesting since the newer nuclear bombs are made from the fission of hydrogen atoms. “ In addition to the destructive effect of the explosion itself, the whole material of the bomb would be transformed into a highly radioactive stage. The energy radiated by these active substances will amount to about 20% of the energy liberated in the explosion, and the radiations would be fatal to living beings even a long time after the explosion. ” This is also interesting since this seems to be a warning to everyone on the danger of nuclear bombs. Einstein also issued this warning to Roosevelt in his letter in 1939. This is because there was an apparent danger to the use of nuclear power on the destructive end. Nuclear energy was going to be one of the major energy sources of the future according to Einstein also in his paper to Roosevelt in 1939 “the element uranium may be turned into a new and important source of energy in the immediate future. ” I agree with this statement because eventually the use of fossil fuels will need to be conserved for things other than energy, and nuclear energy is a highly efficient form of energy.
