“Revista istorică”, XXVIII, 2017, nos. 1-2 ABSTRACTS THE ARABS AND THE MONGOLS EXPANDING: A COMPARISON OF THE PREMISES VIRGIL CIOCÎLTAN The route from the nomad’s tent to the imperial palace had the same starting ground, namely the disadvantaged areas, which made their nomadic inhabitants particularly receptive to material gains, and the same finality: expansion and the formation of the two empires. Beyond the specific means of achieving each course individually, their essence was identical: the politic and social instability, which was endemic to the gentile societies of pre-Islamic Arabia and Mongolia before the rule of Genghis Khan, was removed by the great social and political renewals of the 7th, respectively the 12th century, which presented the nomadic inhabitants with a new identity, granted them social homogeneity and integrated them into state structures which superseded the traditional tribal entities. As the conscience of being Moslem transgressed the narrow gentile differences and allowed the formation of the great Islamic community (umma), composed of equal elements, at least in theory, which were unified precisely by the common faith in Allah, so Genghis Khan’s reform, promulgated at the 1206 kurultai, consecrated the victory of the new identity, that of members of the Mongol ulus, which was also of divine right and with similar universal imperial traits. Thereupon, the energies previously consumed in internal conflicts could be harnessed and channeled towards the outer world, where they produced epochal military victories. The analogy between these phenomena and those produced several centuries later by the French Revolution, which made possible, through a similar process of equalization, the “mass uprising” (levée en masse) and, as a consequence, Napoleon’s great conquests, is striking. -

091805 The Secret Hans2.doc Italicized paragraphs not presented September 19, 2005 The Secret Hans Richard L. Garwin at Celebrating an Exemplary Life September 19, 2005 Cornell University I recount1 some early interactions I had with Hans, beginning in 1951. Hans had led the Theoretical Division at Los Alamos from 1943 to 1945, and despite his antagonism to the hydrogen bomb, was willing to turn his talents to learning whether it could be done or not, which was his role when we interacted in the summer of 1951. In May of 1951 my wife and I and our infant son went to Los Alamos for the second summer, where I would continue to work mostly on nuclear weapons. I was at that time an Assistant Professor at the University of Chicago and had spent the summer of 1950 at the Los Alamos Laboratory, sharing an office with my colleague and mentor Enrico Fermi—Hans Bethe's mentor in Rome as well. When I returned in 1951, and asked Edward Teller, another University of Chicago colleague, what was new and what I could do, he asked me to devise an experiment to confirm the principle of "radiation implosion," then very secret, that he and Ulam had invented that February. In May 1951, the young physicists Marshall Rosenbluth and Conrad Longmire were trying to do actual calculations on this method for using the energy from an ordinary fission bomb to compress and heat fusion fuel-- that is, heavy hydrogen (deuterium). I decided that the most convincing experiment would be a full-scale hydrogen bomb, so I set about designing that. -

Director's Office: Faculty Files: Box 25: Pais, Abraham, Permanent Member From the Shelby White and Leon Levy Archives Center, Institute for Advanced Study, Princeton, NJ, USA Dr. Abraham Pais Dr. Pais was born i n Amsterdam on May 19, 1918. He obtained his Doctor's Degree at the University of Utrecht in 1941. During the years of the occupation, he continued to work under conditions of great difficulty, and the year after the war he was an assistant at the Insti- tute of Theoretical Physics in Copenhagen, In the fall of 1946, Dr. Pais came to the Institute for Advanced Study. ~he record of Dr. Pais' work in the last decade is almost a history of the efforts to clar ify our understanding of basic atomic theory and of the nature of elementary particles. Pais first proposed the compensa- tion theories of elenientary particles, and much of his work tas been devoted. to exploring the success and limitations of these theories, and indicating the radical character of the revisions which will be needed before they can successfully describe the sub-atomic world. Pais has made important contri- butions to nuclear theory and to electrodynamics . He is one of the few young theoretical physicists who within the last decade have enriched our understanding of physics. Statement prepared by J . R.

CP Symmetry Violation: the Search for Its Origin.” Reviews of Modern Physics 53 (1981) 373–383
CP SYMMETRY VIOLATION 1 Jonathan L. Rosner The symmetry known as CP is a fundamental relation between matter and antimatter. The discovery of its violation by Christenson, Cronin, Fitch, and Turlay (1964) has given us important insights into the structure of particle interactions and into why the Universe appears to contain more matter than antimatter. In 1928, Paul Dirac predicted that every particle has a corresponding an- tiparticle. If the particle has quantum numbers (intrinsic properties), such as electric charge, the antiparticle will have opposite quantum numbers. Thus, an electron, with charge −|e|, has as its antiparticle a positron, with charge +|e| and the same mass and spin. Some neutral particles, such as the photon, the quantum of radiation, are their own antiparticles. Others, like the neutron, have distinct antiparticles; the neutron carries a quantum number known as baryon number B = 1, and the antineutron has B = –1. (The prefix bary- is Greek for heavy.) The operation of charge reversal, or C, carries a particle into its antiparticle. Many laws of physics are invariant under the C operation; that is, they do arXiv:hep-ph/0109240v2 15 Oct 2001 not change their form, and, consequently, one cannot tell whether one lives in a world made of matter or one made of antimatter. Many equations are also invariant under two other important symmetries: space reflection, or parity, denoted by P, which reverses the direction of all spatial coordinates, and time reversal, denoted by T, which reverses the arrow of time. By observing systems governed by these equations, we cannot tell whether our world is reflected in a mirror or in which direction its clock is running. -

Wolfgang Pauli 1900 to 1930: His Early Physics in Jungian Perspective
Wolfgang Pauli 1900 to 1930: His Early Physics in Jungian Perspective A Dissertation Submitted to the Faculty of the Graduate School of the University of Minnesota by John Richard Gustafson In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Advisor: Roger H. Stuewer Minneapolis, Minnesota July 2004 i © John Richard Gustafson 2004 ii To my father and mother Rudy and Aune Gustafson iii Abstract Wolfgang Pauli's philosophy and physics were intertwined. His philosophy was a variety of Platonism, in which Pauli’s affiliation with Carl Jung formed an integral part, but Pauli’s philosophical explorations in physics appeared before he met Jung. Jung validated Pauli’s psycho-philosophical perspective. Thus, the roots of Pauli’s physics and philosophy are important in the history of modern physics. In his early physics, Pauli attempted to ground his theoretical physics in positivism. He then began instead to trust his intuitive visualizations of entities that formed an underlying reality to the sensible physical world. These visualizations included holistic kernels of mathematical-physical entities that later became for him synonymous with Jung’s mandalas. I have connected Pauli’s visualization patterns in physics during the period 1900 to 1930 to the psychological philosophy of Jung and displayed some examples of Pauli’s creativity in the development of quantum mechanics. By looking at Pauli's early physics and philosophy, we gain insight into Pauli’s contributions to quantum mechanics. His exclusion principle, his influence on Werner Heisenberg in the formulation of matrix mechanics, his emphasis on firm logical and empirical foundations, his creativity in formulating electron spinors, his neutrino hypothesis, and his dialogues with other quantum physicists, all point to Pauli being the dominant genius in the development of quantum theory.
