I read this live here ten years but I still recommend to friends. Each chapter deals with a subject and can be read independently of others. Each subject and traveled quite extensively, and we discover the hidden facets, Voires obscure scientific history. The historical and scientific content is solid. This book set off sparks in my mind ... He re-injects a healthy doubt about the great inventions and theories of our time. And what is this doubt? to go further, because the great certainties serve us. They make us believe that our world is well known, finite. There is nothing ... I highly recommend this book.
