Cesar Hidalgo takes information as James Gleick did and puts it into a physical embodiment. Being physical, information suddenly has to exist despite the laws of thermodynamics. Suddenly the sweet spot of planet Earth being so temperate elicits a yet greater reverence for the perseverance of life. Life took an embodiment of information in so many ways, but Hidalgo breaks it down into knowledge and know how, explicit knowledge and implicit knowledge. Great read.
