Fission, and fusion energy:

'The Italian navigator has arrived in  the new world' 

This coded message announced the beginning of the atoyic age on 2nd December? 1942. The 'navigator' was the Italian-American physicist Enrico Fermi. That afternoon, in a squash court under the stadium of Chicago University of USA, Fermi and his team of scientists succeeded in  taming the atom for the first time. In  the heart of  the first atomic ' furnace, atoms were made to split, under strict control, to produce energy. Fermi had  indeed ushered  in a new world. Today, in  the giant atomic power stations around the world, or'in nuclear weapons, we can see how far this discovery has taken us.
