E = mc2
Einstein's famous equation combines the idea of mass and the idea of energy.
Einstein thought that mass and energy are the same thing and one can be
converted to the other. In fact, there is enough energy in a glass of
water to power a city, the size of Melbourne, for over a week.
The formula was used to explain the enormous energy source fueling our sun.
The reactions fueling our
sun are no ordinary reactions and involve tiny particles (atomic nuclei)
smashing together to form particles that are lighter than the sum of the
reacting particles. The difference in mass is converted to energy according
to the formula E =mc2.
E = energy
m =mass
c= speed of light.
A small mass "m" multiplied by a large number "c2" yields a huge amount of energy.
