    Niels Bohr's Discussions with Albert Einstein, Werner Heisenberg, and Erwin Schrödinger: The Origins of the Principles of Uncertainty and Complementarity.Jagdish Mehra - 1987 - Foundations of Physics 17 (5):461-506.
    In this paper, the main outlines of the discussions between Niels Bohr with Albert Einstein, Werner Heisenberg, and Erwin Schrödinger during 1920–1927 are treated. From the formulation of quantum mechanics in 1925–1926 and wave mechanics in 1926, there emerged Born's statistical interpretation of the wave function in summer 1926, and on the basis of the quantum mechanical transformation theory—formulated in fall 1926 by Dirac, London, and Jordan—Heisenberg formulated the uncertainty principle in early 1927. At the Volta Conference in Como in (...)

  3. Josiah Willard Gibbs and the Foundations of Statistical Mechanics.Jagdish Mehra - 1998 - Foundations of Physics 28 (12):1785-1815.
    In this study, I discuss the development of the ideas of Josiah Willard Gibbs' Elementary Principles in Statistical Mechanics and the fundamental role they played in forming the modern concepts in that field. Gibbs' book on statistical mechanics became an instant classic and has remained so for almost a century.

    Planck's Half-Quanta: A History of the Concept of Zero-Point Energy. [REVIEW]Jagdish Mehra & Helmut Rechenberg - 1999 - Foundations of Physics 29 (1):91-132.
    Max Planck introduced the concept of zero-point energy in spring 1911. In the early struggles to establish the concept of the energy-quantum, it provided a helpful heuristic principle, to guide as well as supplement the efforts of some leading physicists in understanding the laws that applied in the atomic domain. The history and growth of this concept, and its application in the general development of quantum theory during the past many decades are studied under three principal headings: (1) The Birth (...)

    Erwin Schrödinger and the Rise of Wave Mechanics. I. Schrödinger's Scientific Work Before the Creation of Wave Mechanics.Jagdish Mehra - 1987 - Foundations of Physics 17 (11):1051-1112.
    This article is in three parts. Part I gives an account of Erwin Schrödinger's growing up and studies in Vienna, his scientific work—first in Vienna from 1911 to 1920, then in Zurich from 1920 to 1925—on the dielectric properties of matter, atmospheric electricity and radioactivity, general relativity, color theory and physiological optics, and on kinetic theory and statistical mechanics. Part II deals with the creation of the theory of wave mechanics by Schrödinger in Zurich during the early months of 1926; (...)

  13. Climbing the Mountain: The Scientific Biography of Julian Schwinger.Jagdish Mehra & Kimball Milton - 2003 - Oxford University Press UK.
    Julian Schwinger was one of the leading theoretical physicists of the twentieth century. His contributions are as important, and as pervasive, as those of Richard Feynman, with whom he shared the 1965 Nobel Prize for Physics. Yet, while Feynman is universally recognized as a cultural icon, Schwinger is little known even to many within the physics community. In his youth, Julian Schwinger was a nuclear physicist, turning to classical electrodynamics after World War II. In the years after the war, he (...)

    This article (Part III) deals with the early applications of wave mechanics to atomic problems—including the demonstration of the formal mathematical equivalence of wave mechanics with the quantum mechanics of Born, Heisenberg, and Jordan, and that of Dirac—by Schrödinger himself and others. The new theory was immediately accepted by the scientific community.
