Einstein
E = mc2 The words of Einstein about the formula It fallowed from the special theory of relativity that mass and energy are both but different manifestations of the same thing a some what unfamiliar conception for the average mind. Futhermore the equation "E" equal to"mc squared" in which energy is put equal to mass multiplied with the square of the same velocity of light showed that a very small amount 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 way demonstrated by cockroft and Walton , in 1932 experimentally. COCKCROFT AND WALTON LAW : The output from 8 stages voltage multiplier can generate up to 1 KV. The cockcroft - Walton law is a voltage multiplier that converts AC or pulsing DC electrical power from a law voltage level to higher DC voltage level. E = mc2 IN OTHER POINT OF VIEW : From the word
