More than any other subject, science is always advancing and changing. The science you will have acquired in this book gives you a starting point, but to keep that sense of wonder alive it needs to be fed with regular updates. I hope that what you have read so far will have succeeded in whetting your appetite for more. This chapter will help you keep up with what’s happening, but also help you to expand your knowledge in the areas that particularly interest you, whether it’s a small part of science or the whole broad panoply. The sources I am recommending may go into more depth than I have been able to in this book, but they are all designed for those with no prior knowledge – we aren’t talking about venturing into complex scientific papers or coping with the impenetrable jargon of scientists communicating with each other.
