IST DIE QUANTENMECHANIK ODER DAS RECHNEN FUNDAMENTALER? Is quantum mechanics as currently conceived the ultimate theory of nature? In his book "Atomic Physics and Human Knowledge", Niels Bohr argued that because of the uncertainty principle quantum methodology might not be applicable to the study of the ultimate details of life. Delbruck disagreed, claiming that biosystems are robust to quantum disturbances, an assertion that is only partially valid rendering Bohr's argument still significant, even though normally ignored. The methods of the quantum physicist and of the biological sciences can be seen to involve two alternative approaches to the understanding of nature that can usefully complement each other, neither on its own containing the full story.

Kant, Schlick and Friedman on Space, Time and Gravity in Light of Three Lessons from Particle Physics
Erkenn DOI 10.1007/s10670-017-9883-5 ORIGINAL RESEARCH Kant, Schlick and Friedman on Space, Time and Gravity in Light of Three Lessons from Particle Physics J. Brian Pitts1 Received: 28 March 2016 / Accepted: 21 January 2017 Ó The Author(s) 2017. This article is published with open access at Springerlink.com Abstract Kantian philosophy of space, time and gravity is significantly affected in three ways by particle physics. First, particle physics deflects Schlick’s General Relativity-based critique of synthetic a priori knowledge. Schlick argued that since geometry was not synthetic a priori, nothing was—a key step toward logical empiricism. Particle physics suggests a Kant-friendlier theory of space-time and gravity presumably approximating General Relativity arbitrarily well, massive spin- 2 gravity, while retaining a flat space-time geometry that is indirectly observable at large distances. The theory’s roots include Seeliger and Neumann in the 1890s and Einstein in 1917 as well as 1920s–1930s physics. Such theories have seen renewed scientific attention since 2000 and especially since 2010 due to breakthroughs addressing early 1970s technical difficulties. Second, particle physics casts addi- tional doubt on Friedman’s constitutive a priori role for the principle of equivalence. Massive spin-2 gravity presumably should have nearly the same empirical content as General Relativity while differing radically on foundational issues. Empirical content even in General Relativity resides in partial differential equations, not in an additional principle identifying gravity and inertia. Third, Kant’s apparent claim that Newton’s results could be known a priori is undermined by an alternate gravitational equation. -
Tribute to Valentine Telegdi
Tribute to Valentine Telegdi who passed away on April 8th in Pasadena by K. Freudenreich, ETHZ/IPP/LHP Plenary CHIPP Meeting, PSI, October 2, 2006 Val Telegdi: years 1922 - 1943 Born on January 11th, 1922 in Budapest, spent only a few years in Hungary. According to his own words in his younger years he was a master of “involuntary tourism” , participating passively in German occupations in three countries: Austria, Belgium and Northern Italy. He attended grammar school in Vienna and then a technical school in Brussels. From 1940 - 1943 he worked in a patent attorney’s office in Milan. He used to say that - contrary to Albert Einstein in Berne - being on the other side of the fence he really had to work hard. When the Germans occupied Northern Italy Val, together with his mother, fled to Switzerland. October 2, 2006, Plenary CHIPP Meeting, PSI, K. Freudenreich, ETHZ 1/20 Val Telegdi: years 1943 - 1946 After a short internment in a refugee camp he joined his father in Lausanne where he studied chemical engineering at the EPUL with a grant from the F onds Europ´een de Secours aux Etudiants. At the EPUL he also attended lectures in theoretical physics given by E.C.G. Stuckelberg¨ von Breidenbach whom he estimated very highly. Ironic telegram by Gell-Mann to “congratulate” Feynman for his Nobel prize: “Now you can give back my notes”, signed Stuckelberg¨ Stuckelberg¨ helped Val to be accepted by P. Scherrer at ETHZ.

V.Y. Glaser SOME RETROSPECTIVE REMARKS by Ph. Blanchard
V.Y. Glaser SOME RETROSPECTIVE REMARKS by Ph. Blanchard OPENINGS MATHEMATICS IN PHYSICS GREAT ENCOUNTERS ALONG THE WAY Zagreb, Göttingen, Copenhagen, Geneva, Strasbourg, Bures sur Yvette USING MATHEMATICS WITH CLARITY AND ELEGANCE Quantum Mechanics, Quantum Field Theory O P E N I N G S I am happy to have been asked to speak about Yurko Glaser, his thinking and its actions. It is an honor for me to pay tribute to the brilliant achievements of this leading mathematical physicist, gifted teacher and exceptional friend. It was in Strasbourg at the spring meeting of the RCP 25, where we first met 1967. At this time I was in Zürich at the ETH, working on the Paul-Fierz model of the infrared catastrophe under the direction of Res Jost. Yurko was born on April 21, 1924 just before the discovery by Schrödinger, Heisenberg, Dirac, Born … of modern Quantum Theory in the mid 1920’s. Carlo Rubbia was also born in Gorizia, Görz, Friaul – Julisch Venetien. Quantum Theory before 1925 – the Old Quantum Theory (Planck, Einstein, Bohr, Sommerfeld …) – was part craft part art. Old principles had been founded wanting, new ones had not yet been discovered. Modern Quantum Theory was a real revolution of our understanding of physical process. Compared with this change, Einstein’s relativity, born in 1905, seem not much more than very interesting variations on nevertheless classical themes. Yurko studied at the University of Zagreb, where he received his Diploma in 1950 and his Ph.D in 1953 under the supervision of W. Heisenberg. He moved to Göttingen in 1951-1952 and made his first important contributions to physics, a book of QED published 1955 in Zagreb and outstanding results on QFT, the attempt to clarify the compatibility of special relativity theory with Quantum Theory. -
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. -

Lif e as a student My extraordinary first-hand introduction to the Feldverein took place 35 years ago, during the year 1 spent at the IHÉS. The path 1 followed from Princeton to Bures-sur-Yvette had a definite random element, so please bear with a bit of autobiographical perspective. 1 began as an undergraduate majoring in experimental chemistry, originally thinking of going into medicine, but eventually moving toward the goal to become a theoretical chemist. With luck, 1 received a Marshall Scholarship to do just that in Cambridge, and upon advice from my undergraduate mentor Charles Gillispie, 1 applied and was admitted to Clare College. But the spring before sailing with the other Marshall scholars to Southampton on the QE II, second thoughts surfaced about continuing in chemistry. -
Rudolf Haag's Legacy of Local Quantum Physics And
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.
