THEN & NOW - A new AdP section dedicated to the history of physics

"Then & Now" is a series of brief historical essays and part of the new "Physics Forum" which also includes further editorial material, comments and the "Expert Opinions". The "Then & Now" section is edited by Dieter Hoffmann and Christian Joas. Historical events and highlights are set in context of ongoing research efforts and recent achievements in physics. It is an attempt to bring together professional historians of science and working physicists. The length of contributions is intentionally limited to 2-3 pages in the new Annalen der Physik. AdP format style files can be found here. As such, the articles give a concise but vivid view on highlights in the history of physics. The contributions are based on invitations, but the editors are also available for your article ideas. Please contact us prior to preparing a manuscript ( All "Then & Now" contributions are available as open online articles.

Dieter Hoffmann and Christian Joas are members of the interdisciplinary project "History and foundations of quantum physics" (, a joint project by the MPIWG and the FHI which is funded by the Strategic Innovation Fund of the President of the Max Planck Society (MPG).

Dieter Hoffmann is Research Fellow at the Max Planck Institute for the History of Science (MPIWG) and adjunct Professor at the Humboldt University in Berlin. He graduated from Humboldt University in Physics where he earned his PhD and habilitation in History of Science in 1976 and 1989, respectively. From 1976 to 1990 he was a Research Fellow at the GDR Academy of Sciences, and subsequently at the Physikalisch-Technische Bundesanstalt, and a Humboldt Fellow at Stuttgart, Harvard, and Cambridge. His research is focused on the history of science and physics in the 19th and 20th century, in particular on biographies and institutional histories. Joas
Christian Joas is a Research Scholar at the Fritz Haber Institute of the Max Planck Society (FHI). After completing his PhD in theoretical physics at Freie Universität Berlin in 2007, he was a Postdoctoral Research Fellow at the MPIWG. His research is focused on the history of 20th century physics, especially on the genesis and applications of quantum mechanics, as well as on the history of processes of knowledge transfer in the modern physical sciences, e. g., between high-energy and condensed-matter physics, or between physics and chemistry.
