To be able to read a book which is able to teach its reader the wonder of light which we ordinary people just take for granted, to find out how it is possible for you get all those colours in bubbles and the diffraction of cd's just blew my mind and how light acts as it travels through glass. Ordering the book I didn't think I would find this book a great as it was, if you're a person who loves to know the world and how it is just read this book. But I would like to worn you that you will need to openly trust what this man says in order to understand it he says he is just telling you how it really is and its up to you to believe it.
