When people use spam-blocking email addresses it is impossible to thank them by email, so this is a public "Thank You" to Mark Thorson for the fabulous present that just turned up at my place. I am about to catch a plane to the Great Australian Science Show, but there is still just enough room in my bag for this wonderful book. I was planning to do some arm-pushing demonstrations at the show, but now I will be able to study to be a real expert.
