What is information? Well Jim Al-Khalili (and that's Professor Jim Al-Khalili to you lot) sees it as a basic component of the universe like energy. In his video 'Information', part of the BBC's 'Order and Disorder' series, he clearly explains what that means in typical Al-Khalili style. So pay attention! To readers of my book the video also provides further details of a number of the necessarily brief references that are included in the book.
