The matter of a whatever body, contains in itself a sum of energy which is represented by the entire mass of the body, as if it would move all together and in one block in the space, at the same speed of the single particles. [...] The equation mv2 gives us the “forza viva”22 and the equation mv2/8338 gives us, in calories, such energy. Thus, if m = 1 and v = 300 millions of meters [per second], which is the speed of light, admitted also for the ether, everyone could see that the result is an enormous quantity of calories such as 10974 followed by 9 zeroes, such as more than 10 millions of millions of millions (p. 458-9)".
