Ruska would be awarded the Nobel Prize in Phyics in 1986 (!) for this work on the invention of the electron microscope. [++] [HEISENBERG] This is the second of a three-part groundbreaking paper by Heisenberg, all appearing in the Zeitschrift in volumes 77, 78, and 80. [++] "(These three papers) mark the transition to the modern view on nuclear forces." (Abraham Pais, "Inward Bound," p. 413) contributing to understanding the behavior of atomic nuclei using quantum principles. It also laid the groundwork for the proton-neutron model of the nucleus, which later became fundamental in nuclear physics, transitioning further from classical to modern physics, influencing the development of particle physics. [++] "Heisenberg s foremost scientific concern after 1927 involved the search for a consistent extension of the quantum formalism that would yield a satisfactory unification of quantum mechanics and relativity theory. This required the formulation of a covariant theory of interacting particles and fields that accounted for elementary processes at high energies and small distances. In 1929, drawing upon the work of Dirac, Jordan, Oskar Klein, and others, Heisenberg and Pauli succeeded in formulating a general gauge-invariant relativistic quantum field theory by treating particles and fields as separate entities interacting through the intermediaries of field quanta. Soon after the discovery of the neutron in 1932, 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 one 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."--Complete DSB online.
