“On Sept. 27, 1905, Albert Einstein‘s paper “Does the Inertia of a Body Depend Upon Its Energy Content?” was published. It was the last of four papers he submitted that year to the journal Annalen der Physik. The first explained the photoelectric effect, the second offered experimental proof of the existence of atoms, and the third introduced the theory of special relativity. The last and final paper of the series introduced m = E/c2, which was later streamlined to its now instantly recognizable form.”
