The Ernst Gehrcke Papers

The Max Planck Institute for the History of Science has recently acquired what has been preserved of the Ernst Gehrcke Papers. Parts of these papers will be digitized and made accessible.

From 1902 until 1946, Gehrcke, an experimentalist and specialist in optics, was employed at the Physikalisch-Technische Reichsanstalt, and became director of the department of optics in 1926. Ernst Gehrcke is known as a fervent critic of Einstein and a leading figure among Einstein's German opponents. The Ernst Gehrcke Papers contain correspondence with the physicists Philipp Lenard, Stjepan Mohorovicic, Ludwig Glaser, Hermann Fricke, Johannes Stark, Otto Lummer and the philosophers Oskar Kraus, Melchior Palagyi, Leonore Frobenius-Kühn, and others; numerous offprints and booklets; some drafts and manuscripts by Gehrcke, for example, Über das Uhrenparadoxon in der Relativitätstheorie and Die erkenntnistheoretischen Grundlagen der verschiedenen physikalischen Relativitätstheorien, and all the parts which were rescued from the Gehrcke newspaper article collection.

Archives Henry Poincaré

Between 1880 and 1930 mathematical and theoretical physics underwent substantial changes. on the one hand linked to the emergence of several fields of mathematics (group theory, algebraic geometry, topology) and on the other hand the disintegration of the Newtonian physics under the effect of the discovery of the electromagnetic waves, the X-rays, the radioactivity, the electrons, and the quantum energy. It is specific to the French scientist Henri Poincaré (1854-1912) to have participated in all these transformations. At the age of 26, Poincaré discovered the theory of Fuchsian functions, thanks to which one could resolve any linear differential equation with algebraic coefficients. The impact of this discovery was to make him corresponding member of the German Academies, even before being nominated for a chair of mathematical physics at the Faculty of Sciences and elected as member of the Institute. Throughout these positions, Poincaré influenced French mathematical research for more than 25 years while pursuing his teaching and research activities. At his death in 1912, he had published some 600 articles on pure mathematics, geometry, celestial mechanics, physics, and philosophy of science.

Notebooks of Einstein and Minkowski in the Jewish National & University Library

The Jewish National and University Library keeps some of the most important sources documenting the emergence of modern physics, among them notebooks of Albert Einstein and Hermann Minkowski.

Lecture Notes taken by Walter Zabel

Walter Carl Ferdinand Zabel, born 1892 in Bromberg/Posen, studied from summer 1911 to summer 1912 in Breslau and from winter 1912 to summer 1914 in Göttingen. From 1914 to 1919 he joined the military service, but must have had time to hear a lecture of Einstein in the winter 1917/18 at the university of Berlin without being registered. From 1919 to 1920 he finished his studies in Halle and worked afterwards until his retirement in 1957 as a teacher at a gymnasium in Berlin-Tempelhof. He died in 1968 leaving behind two carefully written volumes with lecture notes.

The first volume contains essentially a comprehensive lecture of David Hilbert on the foundations of mathematics. As an appendix to this lecture, Zabel copied a publication of Minkowski's famous 1908 lecture on space and time. The second volume begins with another lecture of Hilbert, a lecture on analytical mechanics at the university of Göttingen in winter 1913/14. The volume continues after the interruption of Zabel's studies with a lecture of Grammel on hydrodynamics at the university of Halle in summer 1919. The volumes ends with notes taken at Einstein's lecture on statistical mechanics at the university of Berlin in Winter 1917/18. In contrast to other lecture notes, these notes are written on bad quality paper and incompletely worked out, obviously as a consequence of the war. Zabel kept, however, stenographic notes of the parts missing at the end.
