Input: Consider 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

Input: Consider Input: Excellent introduction to the field for physicists . Perhaps the best feature of this book is that it aims to convey the theory of Lie algebras and Lie groups to physicists. In doing so, the author is careful to give a very simplistic approach so that one not familiar with the subject can understand it. Not to say that the book is elementary, since it builds rapidly into the far more interesting aspects of Lie Groups. A very good read

Output: POS

Input: Consider Input: Get the Whole Collection, good booklets for the novice . I personally like all of Baba Raul Canizare's booklets on the Orishas, each booklet comes with various Patikis "Orisha Mythology and Legends" Songs, Chants, and Prayers. These booklets are a collection of the most popular Orishas as worshipped in the Orisha tradition of Lucumi. They are just booklets, and are good for the novice in the religion, or those who are curious about a certain Orisha. Worth the 4.95. Check out the whole collection.
