The APS Annual Leadership Meeting will be taking place this week on Thursday 2/4 and Saturday 2/6. This is usually an in-person meeting in DC, so registration is usually limited to the leadership of APS Units, but this year it’s virtual and they have extended registration to all APS members for free (it might be free to nonmembers, but I am not sure).
I attended last year and it was an extremely valuable look at the work that APS does to advance physics, from organizing conferences to interacting with the congress and federal agencies to advance policies to strengthen scientific research. That includes obvious things, like most science funding, and less obvious things, like ensuring an adequate supply of liquid helium.
