"THE ENERGY OF A FINITE MASS BECOMES INFINITE" EINSTEIN, ALBERT. Typed Letter Signed, "A. Einstein," to a student, Dale B. Swanson, explaining some properties of mass and energy as they relate to velocity at the speed of light. 1/2 page, 4to, "Institute for Advanced Study" stationery; folds. With the original envelope. Princeton, 5 January 1954

  • Notes: "One should speak of mass only in the sense of something characteristic for the body and independent of its motion. Now it is true that the energy of a finite mass becomes infinite, provided the mass is finite. In the case of the photon the mass has to be assumed zero or infinitely small in such a way that in spite of its having the light velocity its energy is finite."
