The Information (James Gleick)

A fascinating examination of what information is (knowledge, uncertainty, meaning, and bits) and how our understanding of and relationship to information has changed over time. It starts with the pre-literate communication of word and talking drums and works its way up, through writing, printing, telegraphy, radio, computers, and the Internet, to Google and Wikipedia. There is much to enjoy here. I loved learning about how talking drums actually talk, about the Analytical Engines of Babbage (never quite realized) and MIT (which took up a room and actually worked to solve differential equations). The controversies over whether information has a thermodynamic cost or whether Wikipedia should include a page on one screw in one particular bicycle were a delight to behold. I highly recommend this book to anyone interested in this sort of history and philosophy of ideas.
