"...the development of the theory of relativity ( Einstein's Theory of the Atomic Bomb -1905) was that the inertial mass of a
moving body increased as its speed increased. This implied an
equivalence between an increase in energy of motion of a body,
that is, its kinetic energy, and an increase in its mass... but as early as 1905
Albert Einstein did clearly state that mass and energy were equivalent and suggested
that proof of this equivalence might be found by the study
of radioactive substances. He concluded that the amount of
energy, E, equivalent to a mass, m, was given by the equation
E = mc2 where c is the velocity of light. If this is stated in actual numbers,
its startling character is apparent. It shows that one kilogram
(2.2 pounds) of matter, if converted entirely into energy, would
give 25 billion kilowatt hours of energy. This is equal to the
energy that would be generated by the total electric power
industry in the United States (as of 1939) running for approximately
two months. "
This new phenomenon would lead to the construction of bombs,
and that extremely powerful bombs of a new type may thus be constructed. -- Albert Einstein -1939
