Since Covid-19 lockdown in March 2020 we organize on-line seminars on phenomenology/theory/astrophysics/cosmology, and whatever can be interesting in theoretical physics. We have no fixed dates and time, see the timetable (European, CET).
Video recordings of most seminars are available on the YouTube channel "Newton 1665 physics seminars ."
If you wish to receive announcements of future seminars: add your email to the mailing list https://groups.google.com/forum/#!forum/physem/join.
If you wish to suggest seminars and/or help organizing: email to organizers (firstname.lastname@example.org).
