It is biggest scientific rumour of all time, Einstein major works has nothing to do with this, first nuclear reaction was conducted by Enrico Fermi and einstein is the one who unequivocaly spoke against nuclear proliferation. All he did was to calculate a formula of mass-energy conversion, the famous, E=delta(m)C(squared)
