How would you go about rebuilding a technological society from scratch If our technological society collapsed tomorrow what would be the one book you would want to press into the hands of the postapocalyptic survivors What crucial knowledge would they need to survive in the immediate aftermath and to rebuild civilization as quickly as possible Human knowledge is collective distributed across the population. It has built on itself for centuries becoming vast and increasingly specialized. Most of us are ignorant about the fundamental principles of the civilization that supports us happily utilizing the latestor even the most basictechnology without having the slightest idea of why it works or how it came to be. If you had to go back to absolute basics like some sort of postcataclysmic Robinson Crusoe would you know how to recreate an internal combustion engine put together a microscope get metals out of rock or even how to produce food for yourself Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ but first it explains the fundamentals upon which they are built. Every piece of technology rests on an enormous support network of other technologies all interlinked and mutually dependent. You cant hope to build a radio for example without understanding how to acquire the raw materials it requires as well as generate the electricity needed to run it. But Dartnell doesnt just provide specific information for starting over he also reveals the greatest invention of them allthe phenomenal knowledgegenerating machine that is the scientific method itself. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world. show more
