Abstract
ON December 28, during the meeting at Pittsburgh of the American Association for the Advancement of Science, Prof. A. Einstein delivered the Josiah Willard Gibbs Lecture of the American Mathematical Society. The accompanying summary was provided by Prof. Einstein for the use of Science Service: βIt is well known that the equivalence between energy and inertial mass is one of the most important consequences of the special theory of relativity; this principle forms at present a useful tool of research in the physics of atomic nuclei. The theoretical derivation of this principle of equivalence, while restricting myself to what is conceptually necessary, is the subject of my lecture. From the Lorentz transformation and the assumption of the impulse and energy principle for material particles, the form of the impulse and energy of the moving particles, as well as the equality of mass and rest-energy, is derived. The whole proof is based on the consideration of an elastic and an inelastic collision between two identically constituted material particles.β
