  • Kant, Schlick and Friedman on Space, Time and Gravity in Light of Three Lessons from Particle Physics

    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.

    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.

The ionosphere was discovered during Karl Rawer's life, and he has dedicated his life to the exploration of this part of Earth's environment. The horrible events of world wars I and II shaped his early life, but they also launched his career as one of the eminent geophysical scientists of the twentieth century. The paper looks back at Karl's life and the 35 years of research and development in the framework of the IRI project. K. Rawer initiated this international modeling effort and was the first chairman of the IRI Working Group. IRI is a joint project of the Committee on Space Research (COSPAR) and the International Union of Radio science (URSI) that has the goal to establish an international standard model of the ionospheric densities temperatures, and drifts. © 2004 COSPAR.

Box 13, I-00044 Frascati, Italy 2)Max Planck Institute for the History of Science, Boltzmannstraße 22, 14195 Berlin, Germany Abstract We describe how the first direct observation of electron-positron collisions took place in 1963-1964 at the Laboratoire de l’Accel´ erateur´ Lineaire´ d’Orsay, in France, with the storage ring AdA, which had been proposed and constructed in the Italian National Lab- oratories of Frascati in 1960, under the guidance of Bruno Touschek. The obstacles and successes of the two and a half years during which the feasibility of electron-positron col- liders was proved will be illustrated using archival and forgotten documents, in addition to transcripts from interviews with Carlo Bernardini, Peppino Di Giugno, Mario Fascetti, Franc¸ois Lacoste, and Jacques Ha¨ıssinski. arXiv:1812.11847v2 [physics.hist-ph] 22 Nov 2019 Drawing by Bruno Touschek (Amaldi 1981).

Il y a fait sa thèse sous la direction d’Yves Rocard et de Pierre Aigrain, et y a exercé jusqu’en 1968. Il rappelle, comment, de 1946 à 1960, ont pu être réunies les condi- tions de la renaissance de la science dans un Le laboratoire de physique de l'ENS, vu de la rue Lhomond en 1950 (archives de l'ENS).
