Monday: With some of us focused on dating right now, the free Gresham College talk tonight at 6pm might be useful: In the Brain of the Beholder? The Principles of Beauty and Sex Appeal. At the Museum of London's ace new lecture theatre.
Tuesday: Not at work today? There are all sorts of funky free things happening at the Natural History Museum (and not just today). Check out the new Nature Live talks, free and open to all, in the new Attenborough Studio. Discover a World of Worms today at 2.30pm.
Wednesday: There's a talk courtesy of Greenwich Historical Society tonight about the Soames Family.
