Mass–energy equivalence - Wikipedia, the free encyclopedia




Mass–energy equivalence - Wikipedia, the free encyclopedia: "Einstein was not the first to propose a mass–energy relationship (see the History section). However, Einstein was the first scientist to propose the E = mc2 formula and the first to interpret mass–energy equivalence as a fundamental principle that follows from the relativistic symmetries of space and time."
