Input: 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 "Plate-tectonic theory and its geological corollaries". 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
Output:
POS
