Oh, I Got the Information, All Right
James Gleick's The Information is a worthwhile read, but I was left a bit cool towards it in the end. The book takes a sweeping look at information science, which largely took shape alongside the development of communications technology and early computing in the nineteenth and twentieth centuries. It's an impressive traversal, and much of the recent thinking on information — its existence as a physical phenomenon, its relation to entropy and importance in quantum mechanics — is exciting and heady stuff.
Unfortunately Gleick includes some incongruous detours, and wraps up the book by steering it into a discussion of Internet age concerns that's much weaker than his science writing. As a result, it feels like the main thread of the book disappears early, and even Gleick's sense of the word "information" reverts to a generic use. It's disconcerting, especially since he so well elucidates information's modern refinement into a precise, subtle scientific concept.
Some of the early chapters are the most interesting, partly from the interest of seeing a modern analytical apparatus applied to premodern activity. Gleick aptly begins by discussing West African "talking drums," an intervillage communication system that was unbested before the telegraph in its delivery speed. As much as any later system it can be analyzed as encoded information, in this case an approximation of speech using only its syllable patterns and tone, high or low. The translated content seems loquacious and overly poetic at first, but as Gleick describes it, it's a now-familiar matter of building in redundancy to prevent error. The alphabet gets an early chapter too, maybe relating a bit less to rarefied information flow but certainly representing an easily overlooked phenomenon of information encoding. (And not an inevitable one; unlike, say, agriculture, the alphabet was only invented once.)
There's a wonderful chapter on Charles Babbage, nineteenth-century Englishman and scientific polymath who invented a steam-powered computer tantalizingly out of practical reach. He kept an equally fascinating correspondence with Ada Byron, daughter of the poet, who as an incredibly talented mathematical amateur even more overtly conceived of computing and programming before it really existed as such. (You get a strong sense here of the western world not exactly taking full advantage of its female minds.)
As for the modern science, it's not particularly easy to wrap your mind around it, but Gleick writes well about the things that are going to go over your head. The useful nickel takeaway, as I absorbed it, is understanding information as a property of physical reality, an inherent quality of organized existence in opposition to entropy. I will admit to still being somewhat fuzzy on the details. And I find quantum computing interesting, but for now I will mostly have to take people's word for its operation.
Reading The Information reminded me that I never actually got around to reading Chaos, beyond looking at the color plates of the Mandelbrot Set. Maybe that'll go on the reading list at a later date.
