History
While Einstein was the first to have correctly deduced the mass–energy equivalence formula, he was not the first to have related energy with mass. But nearly all previous authors thought that the energy which contributes to mass comes only from electromagnetic fields.[27][28][29][30]
<<Table of Contents In physics, mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. What we ordinarily call the mass of a body is always equal to the total energy inside, up to a factor that changes the units. Or: | Next>> | Show All>>
