Plate Tectonics as told by those that assembled the theory . This is a highly informative account of both the ideas that led to the development of Plate Tectonic theory and the concepts of how the earth works. The book is engaging to read and is understandable to an audience at the level of Scientific American. I am using it as a required text in my course at Columbia University titled &quot;Plate-tectonic theory and its geological corollaries&quot;. For those fascinated in how the human mind puts observations together to build ideas and then test them, this book is first rate. Each chapter is crafted by a different researcher describing his or her contribution to the over all theory. The reader encounters brilliant and original ideas discarded by peer review, scientists peeping over each other's shoulder, the rush to the goal line to publish first, competition for access to key data sets, a last minute conversion from the static earth perspective, and the thrill of exploration at sea. The authors presents a wonderful history in Chapter 1 of the intellectual passage from the first inkling of continental drift in the 16th century to the breakthrough in 1966-1968 of the full-blown theory of rigid lithosphere paving stones and narrow plate boundaries

Really just fantasic! . When I first saw this book in the bookstore, I debated about getting it for about a month. The moment I bought, I regretted it. This book was so fanastic, you shouldn't hesitate! The back cover makes the book sound stupid, and the front cover art is slightly freaky, but the book itself was actually really, really good. Masterful writing combined with poetic development of characters and setting makes the novel flow. The transtitions and changes that the main characters have to go through, the challenges they face, and the triumphs and discoveries that they encounter will have you devouring the book in a day or less. Honeslty, don't hesitate when thinking about buying this book. It will become a treasured piece of your collection

Ahead of his time . JA Rodgers was ahead of his time when it came to historical reserch. He exposed alot of things that even in our xenophobic world we are afriad to talk about. He discovered through his reserch many of the great people of the past was infact blacks,and that they had been covered up by white wash over centuries. People should read these books with an open mind,because it explains alot in our soceity that are very race conscious people. I learned about Al Jahiz though him and he taught me about many great people I had never even heard of. I never knew about lokman the southern Arabian sage that was considered one of the wisest men. I never knew about the black vikings in this book called blaumen. The book also discussed how many people of the royal family have indeed black ancestry and how they have tried to hide these facts. Get this book to expose the truth and check out other JA Rodgers books
