It's E=mc2 , and it's a by-product of the calculations in one of Albert Einstein's publications.
I don't know who came up with E = mc, but Einstein came up with E = mc2.
Erwin Chargaff
Albert Einstein
He came up with the formula E=MCsquared.
the person who came up with that is pythagoris, and it is called the pythagrian theorem.
Euler
Tricycle
the circle
Daniel Pater came up with the original formula that came to be the first successful milk chocolate in the world in 1887.
He was smart because thats the way he was born. He came up with e equals mc2
Einstein came up with E=mc^2 as part of his theory of special relativity to show the relationship between energy (E), mass (m), and the speed of light (c). This formula explains how mass can be converted into energy and vice versa, leading to groundbreaking insights in physics.
the answer is E equals to 12.5 but i dont know how it came up with it.
