First printing of Heisenberg's groundbreaking neutron-proton model. The three papers "mark the transition to the modern view on nuclear forces." (Pais. Inward Bound. P. 413). Shortly after Chadwick discovered the neutron in 1932, Heisenberg developed a theory suggesting that atomic nuclei are composed of protons and neutrons. This introduced the concept of the nuclear exchange force and isotopic spin.

"Soon after the discovery of the neutron in 1932 [By Chadwick], Heisenberg developed a neutron-proton model of the nucleus by introducing the concept of the nuclear exchange force and the formalism of isotopic spin. Nonrelativistic quantum mechanics could be applied to the nucleus, Heisenberg showed, as long as long as on did not consider the structure of nucleons. Heisenberg's work served as the basis for contemporary nuclear physics, of fields. In 1935 Heisenberg and his assistants, especially Weizsäcker. Heisenberg preferred to continue the search for a consistent quantum physics, much of which was pursued by his assistant Hans Euler discovered that nonlinear interactions in positron theory, which yielded photonphoton scattering, could be represented by treating the electron as possessing a minimum size, below which the interferences predominated." (DSB).

Heisenberg played an important role in the unsuccessful attempt German attempt to build a nuclear reactor.

The three volumes contain numerous important contributions by contemporary physicians.
