I’m excited. Really. I have just discovered that my friend Mark Miodownik is going to deliver the Royal Institution Christmas Lectures this year. Mark is a materials scientist at King’s College (where, outrageously, the Materials Science Department is no more). He runs the wonderful Materials Library, where one can see and touch lots of very weird materials. I can think of no one better to fill Michael Faraday’s shoes for the Christmas Lectures, and I plan to be there.
