I meant to tell you about this on Thursday or Friday, but I had to focus on the Southern California String Seminar, and so did not get to it sooner. So you might not get to listen to it as part of a Sunday afternoon relaxation.
The Royal Society gave an award to Stephen Hawking on Thursday, and the BBC took the opportunity to make a special effort to cover some very good science discussion, as a sort of away mission for the Radio 4 Today program. You can go to the Royal Society’s site with all of the interviews (with Martin Rees, Stephen Hawking, Lewis Wolpert, and John Krebs among others) on various subjects. The last two interviews have comments about ethical implications of scientific research, and about whether the public can trust the information they are given by scientists, respectively. I’ve not listened to those yet, but I bet they’ll be interesting.
You can listen to the whole thing in one continuous block by going to Radio 4’s listen again archive for Radio 4’s Today programme, clicking on the Thursday link (before it gets over-written by the next Thursday programme).
Radio 4’s In Our Time last week also had some interesting material. It was all about the speed of light. This is particularly timely in view of the [
sometimes morbidly fascinating] discussion going on about varying the speed of light on another thread. The programme features John Barrow (Cambridge), Iwan Morus (Universirt of Wales, Aberystwyth), and Jocelyn Bell Burns (Oxford). Programme here. (Although you might have to go to the archive page here after Thursday to find this episode.)
(*Thanks Ed Copeland!)
[Update: Andrew Jaffe also talks about these programmes.]
