First printing of Fermi's paper on the impact between atoms and electrically charged particles.

In statistical mechanics he had written subtle papers on the ergodic hypothesis and on quantum theory. Here he had developed an original form of analyzing collisions of charged particles. He developed the field produced by the charged particle by the Fourier integral and used the information from optical processes to determine the result of the collision. This method was later refined and better justified on the basis of quantum mechanics and is generally known as the Weizsäcker-Williams method.
