One of the few upsides of Covid-19-enforced shift to remote work in academia was the rapid improvement in accessibility of research. You no longer had to be at the particular place at the right time to hear about the most recent work on something you're interested in, or interact with some big name, or just to hang around and chat and check out the community. (An honorable mention goes to the Geneva Symmetry Group and the Black Hole Initiative, which were functioning partially online long before 2020.) On a slightly more lofty note, inclusive education is a human right; academic research wants to be free; and equality, openness, and ease of access to knowledge simply are of fundamental importance for the functioning of democratic societies. Many people, and big kudos to them, continue to organize their seminars and talks series in either fully remote or hybrid modes; for mathematics and theoretical physics, researchseminars.org is a useful central resource. (This is also as good a place as any to digress with one of my pet peeves: that every university should have an equivalent of talks.cam for their local on-site events. Anyway...) Below is a list of Zoom/Teams/otherwise in-real-time accessible and free to access --- though mostly requiring registration to avoid Zoom bombing --- talk series, seminars, and reading groups in philosophy of physics, foundations of physics, and broadly related to that philosophy of science and HPS.
I am keeping this list up to date; please let me know if you'd like your series either added or removed, or if you spot any outdated information. All times below are in CE(S)T. Last update: 25.2.2025.
