The Information: A History, a Theory, a Flood

Gleick traces the idea of information from African talking drums encoding tonal language across distances, through the telegraph, telephone, and Shannon's mathematical framework, to the contemporary flood of data. The book's central argument is that information is not merely a technical concept but a lens through which to understand biology, physics, and culture — that the universe itself computes. Gleick writes with unusual clarity about difficult ideas, making Shannon's entropy, Kolmogorov complexity, and Chaitin's incompleteness accessible without trivializing them. The historical chapters on Charles Babbage, Ada Lovelace, and the early telegraphers are as vivid as any narrative history. It is one of the best syntheses of the intellectual history of computing and communication published in the last twenty years.
