I'm just starting to plan two public lectures that I'm giving in the near future.
The first is at the Rutherford Appleton labs. on Fri. 25th Jan. at 1330-1430 and then again at 1900 - 2000. The second is at the Earth Science dept. in Oxford on Sat. 9th March as part of the Oxford Science festival. Details of these events, which are both free, are on my web site events page.
