27 September 1905 — Albert Einstein submits “Does the Inertia of a Body Depend Upon its Energy Content?” to Annalen der Physik. It is in this article that he first develops what is probably the most popular equation in physics: E = mc2
Ever wonder what that actually means? Yale physics professor Ramamurti Shankar explains the theory of relativity in his “Einstein for the Masses" lecture.
