Welcome to the Swiss Physical Society !

Joint Annual Meeting 2021

The next annual meeting will take place at the University of Innsbruck, in the week of 30 August - 3 September 2021. The well established tradition of organising the conference every second year jointly with the Austrian Physical Society (ÖPG) will be continued, possibly again with contributions from further partners. An interesting and rich program is thus guaranteed.

Save the date !

It is your conference, so we welcome contributions from all topical fields. The detailed announcement will be available soon.


  • The SPS Communications No. 64 will appear presumably in June 2021.

Wilhelm Conrad Röntgen Symposium

On Saturday 18 September 2021, a public symposium is dedicated to the physicist Wilhelm Conrad Röntgen (1845 - 1923). In 2020 his 175th birthday and the 125th anniversary of his discovery of X-rays should have been celebrated, but the occasion had to be shifted to 2021 due to the pandemics. The symposium will take place at the ETH Zürich / Hönggerberg. Several talks will highlight Röntgen's biography, as well as the current state of research and applications, in which X-rays play a fundamental role.

Since the combination of history and modern research is particularly attractive to young people, the organizing societies plan a special program in the morning before the Röntgen Symposium, where selected students, namely winners of the SwissPhO and similar competitions, can visit physics laboratories on Hönggerberg and get first-hand information about current research activities.

The public is cordially invited to attend the symposium lectures that will be given in English; admission is free and registration is not required.

The Young Talents Day and the Wilhelm Conrad Röntgen Symposium is jointly organized by the Swiss Physical Society SPS, the Physikali­sche Gesellschaft Zürich PGZ, and the Swiss Academy of Sciences SCNAT.

Symposium program:

  • 13:15 - 14:00: Ralph Claessen, Universität Würzburg, Röntgen's discovery: from serendipity to scientific revolution
  • 14:00 - 14:45: Marco Stampanoni, ETH Zürich, 125 years of X-ray imaging and still eager to push further
  • 14:45 - 15:15: Kaffepause
  • 15:15 - 15:45: Clemens Schulze-Briese, Dectris Ltd. Baden, X-rays in industry and society, what we do today and what can be done tomorrow
  • 15:45 - 16:15: Davide Bleiner, EMPA, Progress in small scale X-ray lasers
  • 16:15 - 16:45: Stéphane Paltani, Université de Genève, The revolution of X-ray astronomy
  • 16:45 - 17:45: Apéro




Kalender mit bedeutenden Physikerinnen der nuklearen Astrophysik

Die EU COST Action ChETEC (16117) "Chemical Elements as Tracers of the Evolution of the Cosmos", in der aus der Schweiz Gruppen der Uni Genf, EPFL und der Uni Basel vertreten sind, hat einen Kalender für 2021 herausgebracht, der jeden Monat eine bedeutende Frau der Nuklearen Astrophysik herausstellt.

Frauen haben einen wesentlichen Anteil in der Entwicklung der nuklearen Astrophysik geleistet, mit enormen Beiträgen in Form von astronomischen Beobachtungen, visuellen und spektroskopischen Identifikationen, Sternklassifizierung und Katalogen, Vorhersage und Entdeckung von stellaren Objekten, Design und Konstruktion von Instrumenten, theoretischen und experimentellen Entdeckungen uvm.
Der Kalender würdigt 12 herausragende Frauen, die geholfen haben, die nukleare Astrophysik voran zu bringen. Er kann heruntergeladen und ausgedruckt werden.
