On the subject of the Christmas Lectures, there’s precious little up on the web about them yet. Five’s site lists only the press release announcing mathematician Marcus de Sautoy as the lecturer; the RI’s site has booking information (they’re fully-booked, natch), and the official christmas lectures site currently redirects to the pages for Sir John Kreb’s lectures from last year.
The RI does, however, have a note giving transmission times: 7:15, from Christmas Day. Excellent.
