  • Lee Lorch 1915-2014
    Extract from OP-SF NET Topic #1 --------- OP-SF NET 21.2 -------- March 15, 2014 From: Martin Muldoon [email protected] Subject: Lee Lorch 1915-2014 Lee Lorch died in Toronto on February 28, 2014 at the age of 98. He was known as a mathematician who made life-long contributions to ending segregation in housing and education and to the improving the position of women and minorities in mathematics. Born in New York City on September 20, 1915, Lorch was educated at Cornell University (1931-35) and at the University of Cincinnati (1935-41) where he completed his PhD under the supervision of Otto Szász, with a thesis “Some Problems on the Borel Summability of Fourier Series”. He worked for the National Advisory Committee for Aeronautics (the predecessor of NASA) in 1942-42 and served in the US Army in India and the Pacific in 1943-46. While In India, he took time to contact local mathematicians and his second publication appeared in the Bulletin of the Calcutta Mathematical Society (1945). Some of Lorch’s early mathematical work, arising from the subject of his thesis dealt with the magnitude and asymptotics of the Lebesgue constants, known to form a divergent sequence in the case of Fourier Series. He studied the corresponding question when convergence is replaced by various kinds of summability (Fejér had considered Cesàro summability) in several papers including joint work with Donald J. Newman (whom he had known as an undergraduate at CUNY in the late 1940s). Later, he looked at corresponding questions for Jacobi series. At the same time, Lee and his wife Grace were involved in the struggle against discrimination in housing (in New York), for equal treatment for Blacks in mathematical meetings, and for school integration in the US South.

    LEGISLATIVE RESOLUTION mourning the death of Lee Lorch, distinguished citizen and devoted member of his community WHEREAS, It is the sense of this Legislative Body to honor and recognize individuals who made significant contributions to the human and civil rights of New York State, and therefore it is fitting and appropriate to recognize the life and work of Lee Lorch; and WHEREAS, Born on September 20, 1915 in the borough of Manhattan in New York City, Lee Lorch attended Townsend Harris High School, where he demonstrated a highly developed acumen for mathematics that would portend an extensive and decorated career in academia teaching at renowned colleges and universities in the United States and Canada; and WHEREAS, He later received his undergraduate degree from Cornell University in Ithaca, New York in 1935, and subsequently earned a doctorate degree at the University of Cincinnati in 1941, both of which nurtured his vast talent and allowed him to excel as a mathematician and professor; and WHEREAS, Lee Lorch became disenchanted with his employment in a draft- exempt position during the World War II effort and dutifully served his country by bravely enlisting in the United States Army Air Corps, serv- ing in India and the Pacific between 1943 and 1946; and WHEREAS, Following Lee Lorch's wartime service, he returned to New York City in the spring of 1946 to teach mathematics at the City College of New York and found a dire shortage of affordable housing; and WHEREAS, After tirelessly searching for two years to find suitable accommodations for his family, Lee Lorch was able to secure an apartment in Stuyvesant Town, Metropolitan Life's newly developed residential complex in Manhattan comprised of 35 buildings and 8,759 apartments for middle-income New Yorkers, with a preference for returning U.S.

Robin Wilson, Notices Associate Editor In this issue of the Notices, we reflect on the sacrifices and accomplishments made by generations of African Americans to the mathematical sciences. This year marks the 100th birthday of David Blackwell, who was born in Illinois in 1919 and went on to become the first Black professor at the University of California at Berkeley and one of America’s greatest statisticians. Six years after Blackwell was born, in 1925, Frank Elbert Cox was to become the first Black mathematician when he earned his PhD from Cornell University, and eighteen years later, in 1943, Euphemia Lofton Haynes would become the first Black woman to earn a mathematics PhD. By the late 1960s, there were close to 70 Black men and women with PhDs in mathematics. However, this first generation of Black mathematicians was forced to overcome many obstacles. As a Black researcher in America, segregation in the South and de facto segregation elsewhere provided little access to research universities and made it difficult to even participate in professional societies.

  • 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.

    Rudolf Haag’s legacy of Local Quantum Physics and reminiscences about a cherished teacher and friend In memory of Rudolf Haag (1922-2016) submitted to the Eur. Phys. J. H Bert Schroer permanent address: Institut f¨ur Theoretische Physik FU-Berlin, Arnimallee 14, 14195 Berlin, Germany November 2016 Abstract After some personal recollectioms about Rudolf Haag and his thoughts which led him to ”Local Quantum Physics”, the present work recalls his ideas about scattering theory, the relation between local observables and localized fields and his contributions to the physical aspects of modu- lar operator theory which paved the way for an intrisic understanding of quantum causal localization in which fields ”coordinatize” the local algebras. The paper ends with the presentation of string-local fields whose con- struction and use in a new renormalization theory for higher spin fields is part of an ongoing reformulation of gauge theory in the conceptual setting of Haag’s LQP. 1 First encounter with Rudolf Haag arXiv:1612.00003v1 [math-ph] 30 Nov 2016 On his return from the Niels Bohr Institute in Copenhagen to the University of Munich Rudolf Haag passed through Hamburg to meet his colleague Harry Lehmann, at that time the newly appointed successor of Wilhelm Lenz who held the chair of theoretical physics since the 1920 foundation of the University of Hamburg. It was the year 1958 shortly after the decision to construct the DESY particle accelerator in Hamburg which created a lot of excitement. I had nearly completed my diploma thesis under Lehmann and begun to worry about my career.
