Upon a second reading, this book deserves the 4 star rating I gave it a few years ago. Gleick is an excellent writer, and pulls off an engaging history of Information Theory and it's impact on modern science. Information Theory is like philosophy in the sense that it underlies much of science (physics, chemistry, biology) which represents our formal understanding of the world. And that is not to mention its impact on technology, specifically the digital, which has encompassed our personal and professional lives for the last 60 years. Like philosophy, I feel that I should have learned about information theory much earlier in life. This book goes a long way in filling that gap.
