Introduction to Modern Physics

Nature volume 135, page 251 (16 February 1935) | Download Citation



THE first edition of Prof. Richtmyer's book has been appreciated by so many physicists that the appearance of a second edition is bound to be warmly welcomed, and it is only necessary here to note the chief changes which have been made. An adequate outline of the application of Fermi-Dirac statistics to problems in photo-electricity has been added and the chapter on X-rays brought up to date. The chapter on the structure of the nucleus has been considerably altered in view of recent work on artificial disintegration, and the neutron and positron both find a place, though perhaps a small one in the case of the latter. Two very important new chapters have been included, one on the vector model of the atom and one on the wave theory of matter. The first will be particularly helpful to students, and the latter properly completes a first-class introduction to modern physics.
