Question: 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

Answer: POS


Question: This book really upset my daughter . My daughter's kindergarten teacher read this book to them in class today and they also made an adorable craft of the old lady with cut outs of all of the animals which fit into her apron.  I thought it was so cute and hung it on our fridge.  Soon after I noticed that my daughter was acting upset, when I asked her what was wrong she broke down sobbing about how the old lady dies in the end of the song.  I haven't seen her this upset about anything in a long time.  Even after I explained to her that it was just a story and not real  she still was upset for the rest of the night.  I know that death is a topic that we all need to discuss with our children, but I'm not sure that this is the appropriate way to deal with it.  I have removed the craft that she made so she doesn't need to be reminded of it.  I know that there are a few children in her class who have lost grandparents this year and it just seems like maybe this book could bring up sad feelings for them as well

Answer: NEG


Question: Take what this book has to say with a grain of salt. . The spiritual comments are marvellous, but the factual content is dodgy. Z. seems to think that a woman will always get her period at the same phase of the moon. But the typical 28-day menstrual cycle is *shorter* than the  moon's cycle of 29 1/2 days, so it won't stay in step. (Besides, many  women's cycles are a few days shorter or longer than the average.) Z. also  says the Earth and Sun are getting closer together at the Northern  Hemisphere's summer solstice; that's actually close to aphelion. (It's the  tilt of the Earth's axis that causes the seasons, not our distance from the  Sun.) And as for astrological birth control, and garlic juice as a cure for  cancer...! An inspiring book - but take it with a grain of salt

Answer:
NEG
