"It followed from the special theory of
relativity that mass and energy are both but
different manifestations of the same thing -- a
somewhat unfamiliar conception for the average
mind. Furthermore, the equation E is equal to m
c-squared, in which energy is put
equal to mass, multiplied by the square of the
velocity of light, showed that very small amounts
of mass may be converted into a very large amount
of energy and vice versa. The mass and energy
were in fact equivalent, according to the formula
mentioned before. This was demonstrated by
Cockcroft and Walton in 1932, experimentally."
