I'm a big fan of Richard Dawkins. Although I can't quite bring myself to agree with his views on religion, I'm 99% persuaded. I just can't get rid of that 1% of me that loves the routine and tradition of the Christian tradition. Perhaps it's a legacy of my upbringing and culture more than actual belief?
Anyway, my book of the week is The Magic of Reality. A superb, accessible, simple yet not simplistic introduction to the fundamentals of science. Each chapter deals with the myths around one of the 'big questions', then goes on to answer the question using known science. Fantastic.
