The Knowledge: How to Rebuild Our World from Scratch. by Lewis Dartnell (Apr 17, 2014) This is an interesting book. For science fiction fans, particularly fans of apocalyptic scenarios, from Fallout to the Road, to the Walking Dead, this is really useful reading. The knowledge is designed to be a how-to book for rebuilding the technology that would be wiped out in a global catastrophe. It's kind of fun. The author assumes that the reader enters the text with only a basic understanding of science. Starting out with the basics of immediate survival (food, water, shelter/clothing, medicine, power) Dartnell clearly lays out the situation and general solutions of how to meet those survival needs. I give this book a 8/10 really high for me, and yes I'm wrinkly enough to have survived 4 great disasters in my time with perhaps 2 more to come always ready ....again, but an easier ride with this book in my kit! http://www.amazon.com/The-Knowledge-Rebuild-World-Scratch/dp/159420523X/ref=sr_1_1?ie=UTF8&qid=1401587138&sr=8-1&keywords=The+Knowledge%3A+How+to+Rebuild+Our+World+from+Scratch or the UK paper http://www.theguardian.com/books/2014/apr/03/knowledge-how-to-rebuild-our-world-from-scratch-review
