Alexander Blum

Research Scholar
Research Scholars are early career scholars who have ordinarily already had at least one postdoctoral fellowship or equivalent academic experience. This is the equivalent of an entry-level academic position (e.g. assistant professor in North America, Lecturer in the United Kingdom, Maître de conférences in France). These scholars carry considerable responsibilities (no more than 30% of their time) within their research unit.
Department I
Dr. rer. nat.
1. Mai 2010 to 31. Dezember 2017

I obtained a PhD in theoretical particle physics from the University of Heidelberg (research at the MPI for Nuclear Physics) in 2009. In 2010 I moved into the History of Science, and to the MPIWG, where I started out as a member of the Quantum History Project, which ran until 2012. Since then I have been a Research Scholar at the MPIWG and coordinated the cooperative project with the Lindau Nobel Laureates Meeting Foundation from 2013–2014. I have organized several smaller workshops at MPIWG (and elsewhere) bringing together physicists, historians, and philosophers to discuss the history and foundations of quantum gravity. I also recently co-organized the large conference at MPIWG/Harnack-Haus celebrating the centenary of general relativity in 2015.

My research interests are in the history (and philosophy) of modern physics, lately with a strong emphasis on the postwar period. My current MPIWG research projects focus on the postwar developments of the two great revolutionary theories of the early 20th century, general relativity, and quantum mechanics, with a special focus on attempts to combine the two. I am also currently completing (together with Dean Rickles of the University of Sydney) a commented sourcebook on the earliest attempts to bring together quantum theory and general relativity, which will be published in 2017. In 2017, I will begin teaching at the physics department of the FU Berlin, pursuing a novel approach of teaching advanced (Master’s level) physics classes with a strong focus on historical theory development.
