The Information: A History, A Theory, A Flood [Brossura]

James Gleick, a prominent journalist, biographer of scientists and explainer of physics has usefully turned his attention to the single most important phenomena of the twenty-first century, the study and quantification of information. This book explains, provides a historical context and gives biographies of the most important explorers of information phenomena throughout the centuries. Gleick provides biographical sketches of lesser known figures in the history of information such as Robert Caudrey compiler of the first known English dictionary and John F. Carrington chronicler of "The Talking Drums of Africa"; he (Gleick) gives fuller personal histories of Samuel F. Morse, Charles Babbage and Ada Lovelace; Gleick reserves the most extensive biographical treatment for those who "mathematized" the phenomena of information: Claude Shannon and Alan Turing.

Gleick, a science journalist and chronicler of physics provides interesting background material and simple enough explanations for anyone who wishes to learn about the areas of information theory that influence our times, technologies and businesses. He also gives enough detail for the interested undergraduate student whose field is not primarily in the sciences. But, the unification of science, phenomena, history and biography is also of considerable interest to those like myself who have extensive training in the "information sciences" but seek a wider context for their previously acquired knowledge.

One slight criticism, I have for this otherwise excellent and comprehensive review of the theory of information and its history, is in the area of its relation to physics and the structure of the world (universe). The relationship and application of information theory to physical phenomena is a theory first espoused by Konrad Zuse, a German computer pioneer and Edward Fredkin the proponent of "digital physics". Given that Gleick's attraction and interest for information theory was probably sparked by his study of the history and explanation of physical phenomena, and his penchant for biography I would have expected more background on these explorers of the nature of physical reality as information.

This excellent history of "information science" is a must read for all who seek to understand the phenomena and technologies of the coming century.

I recommend this book's discussion of information theory, a topic that is sadly underrepresented in the popular press. Glieck provides a decent historical overview of Shannon and Turing, and the book starts to pick up steam when discussing Norbert Wiener and cybernetics. The subsequent chapter on informational and thermodynamic entropy is an excellent non-mathematical overview of a tricky topic. It is only surpassed by Chapter 12, which is a fascinating elucidation of algorithmic information theory, which as Chaitlin put it, was "the result of putting Shannon's information theory and Turing's computability theory into a cocktail shaker and shaking vigorously." It's unsurprising that this is Glieck's strength, due to his earlier writing on chaos.

Unfortunately the rest of the book falls far short of this strong standard. Glieck attempts to tackle too much, offering forgettable takes on topics including dictionaries, telegraphs, Charles Babbage, Wikipedia, memes, and information surfeit. These topics are not well-anchored to the central topic of information theory, and serve to muddle the work. But most disappointingly, the chapters on biology (Ch. 10) and quantum physics (Ch. 13) leave a ton to be desired. Glieck barely scratches the surface of the application of information theory to biology (particularly neuroscience), and the discussion of quantum information begs many more questions to be answered. What Glieck does introduce about these topics is disjointed and in need of serious editing. For instance, Glieck introduces Christopher Fuchs and quantum information theory, but before the discussion really goes anywhere, he shifts to a cursory discussion of black holes and information before shifting to an equally vacuous discussion of quantum computation and teleportation.

Thus, I can only half-recommend this book. There are parts I strongly recommend (Ch. 9,12), parts that are pretty good (Ch. 6-8), parts that are tangential and forgettable (roughly half), and other parts that are very disappointing and in need of serious expansion (Ch. 10,13).

Where did the telegraph, telephone and computers come from anyway? Author James Gleick's new book, "The Information" sheds light inside the black box.

In a revealing work, backed by painstaking research, James Gleick, has combed the archives to show us some absorbing details and insights on how the structure of information progressed from clay tablets to telegraph to cloud technology.

This is a hefty book, but its theme can be shortly stated. Mr. Gleick believes "in the long run, history is the story of information becoming aware of itself."

Context can be everything in historical interpretation, as James Gleick makes clear in his convincing prolog that "the alphabet was a founding technology of information; the telephone, the fax machine, the calculator and, ultimately the computer are only the latest innovations devised for saving, manipulating, and communicating knowledge." Mr. Gleick's narrative builds into a fulfilling and thought-provoking story.

The author begins with the amazing tale of how African drums communicated, then shifts to Robert Cawdrey's "Table Alphabeticall in 1604. He shows us how time and space are minimized and global consciousness realized.

At more than 500 pages, with few illustrations, this book looks terrifying. But the pages dissolve quickly as Mr. Gleick introduces us to a range of vivid characters, such as colorful Charles Babbage, the inventor of the ever growing difference machine in 1822.

After twenty years of development it weighed 15 tons with over 25,000 precision parts. But by 1842 the British government had grown weary of Babbage's pork barrel project. "What shall we do to get rid of Mr. Babbage and his calculating machine?" asked Prime Minister Robert Peel. "Surely if completed it would be worthless as far as science is concerned... It will be in my opinion a very costly toy."

But another fascinating part of the story, of course, is of the strange men, and the strange world they inhabited at Bell Laboratories, doing research on code breaking and anti-aircraft gun control during World War II. There was ego and rivalry and brilliance aplenty in those days. We meet Alan Turing, and brillant oddballs like Norbert Weiner and Claude Shannon, who were brought in from other institutions, to imagine and to challenge each other.

This is a book full of great details, like Richard Dawkins's memes: ideas, tunes, catch phases and images that "propagate themselves in the meme pool by leaping from brain to brain" through imitation. Claude Chappe's vast network of optical telegraph towers transferring messages by semaphore across revolutionary France in twelve minutes. And an amazing robot mouse developed by the inventor of information theory, Claude Shannon, that could learn to flawlessly navigate a maze back in 1950.

Some of the narrative may seem pretty heavy- going. For readers who are not versed in the subject, it may seem to be almost impenetrable. After a bit, one realizes this book is not written for the general reader.

Of course, there is nothing inherently wrong with a scholarly conversation and nothing wrong with a book that assumes its readers will already know something about computer science. As a book for specialists this has its pleasures, from Mr. Gleick's learned discussion of boolean algebra to the German ENIGMA code machine in World War II and the workings of a telephone switchboard invented by the George W. McCoy, the world's first telephone operator.

Mr. Gleick's affection for his subject is so complete -- and completely convincing -- his style is so modest and his research is so thorough that "The Information" manages to be engaging, instructive and thought-provoking, all at once.

Scientific work may not be very glamorous, but "The Information" shows that it can be vitally important, and also surprisingly amusing.

The author could easily have written a fine book focused more narrowly on the development of computers. Mr. Gleick is the kind of historian who excels at showing how everything is connected. He tells us, "hardly any information technology goes obsolete. each new one throws its predecessors into relief." In this investigation, few books could provide a surer guide.

Mr. Gleick is familiar with the vast number of written sources. This book is clearly not intended to be the last word on information technology. But for any readers wanting a learned, entertaining and lucid introduction to a notoriously complex subject, it should certainly be their first.
