"It followed from the special theory of relativity that mass and energy are both but
different manifestations of the same thing - a somewhat unfamilar conception for the
average mind.""Furthermore, the equation
E is equal m c-square, in which energy is put equal to mass, multiplied with 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."
Playing the violin, Einstein took a life-long interest in
the arts. After he had achieved international fame, his violin became a kind of
trademark. |
