Today is the 117th anniversary of the completion by Albert Einstein of his paper, Does the Inertia of a Body Depend Upon Its Energy Content?, introducing the equation E=MC², on this date.
Before this, E equaled just about anything you wanted it to equal. Just think what the atomic bomb would have been like if E = grapes seeds or the real content of Schrödinger’s box.
