ClickyThere's stuff in Paul Callaghan's head that could make your brain hurt, but he would rather save you the pain. The Victoria University professor is a world-leading physicist who has been showered with academic prizes, but alongside his work in the arcane field of nuclear magnetic resonance, Callaghan has developed a sideline as a science communicator, including stints on Kim Hill's Radio New Zealand show.
He is one of a lamentably rare breed who not only understand what Einstein and Darwin and Schrodinger were talking about, but can convey it to those of us who struggle to put torch batteries in the right way around; his efforts to bridge the gap between boffins and boofheads were one of the reasons he was last night awarded the Blake Medal for leadership.

A quick question to anyone else: who here has read "The God Delusion" and what do you think of it?
