The RPS has responded to the coronavirus lockdown by running a wide variety of interesting talks and workshops. Many are free (or very reasonable) and all are open to non members (although you may pay a little more). You have to book a ticket via the RPS website and they do fill up! I’ve attended several talks and they have all been very worthwhile.
Also, if you attend one of the online events before the end of May you can get a 20% discount on RPS membership. All the details are here.
