Einstein’s Second Mistake with E=MC. Einstein’s second mistake with his equation was in his failure to realize that the primary meaning of E=MC2is that it defines the mass of the photon as the truest measure of mass. Planck’s constant is equal to the mass of a photon times its wavelength times the speed of light.
