The story of atomic bomb - part1

Albert Einstein, genius of 20 century, proposed E = M*C^2 in a paper published in 1905. He simply said that as C^2 is a very big number, this formula shows that applying to even a very very tiny mass for example in scale of atoms, we get a very huge amount of energy. In 1935, in an interview he honestly expressed that doing it is much more harder and spends much energy than amount of derived E. BUT, at time he never noticed that it may happens so quick when there are very good physicist in Germany who strongly wants to help Nazis to dominate whole world. Later, in 1939 when his German friend, Lion Silad informed him that there are some known way of getting E from atoms easier than what Einstein had supposed, he became so thoughtful and wrote a letter to Roosevelt, US president and...
