A Informação

by James Gleick, Augusto Pacheco Calil (Translator)

O que é a informação? Neste trabalho, o jornalista James Gleick traça uma história desse fenômeno, com seus infinitos desdobramentos e peculiaridades. Partindo da comunicação por tambores na África, ele passa pela criação dos alfabetos e dos dicionários, por invenções como o telégrafo e o telefone e pelos primeiros computadores, até desembocar na chamada Teoria da Informação e em estudos recentes de genética e na já onipresente Wikipedia. A informação não é um livro apenas sobre ideias, mas também sobre pessoas. Ao condensar séculos de estudos e análises a respeito do tema, Gleick vai falar daqueles que estiveram na linha de frente dessa revolução científica. Claude Shannon, Bertrand Russell, Alan Turing, Kurt Gödel e Richard Dawkins - cujo conceito de meme foi apropriado pelas novas gerações - são alguns dos personagens que aparecem, às vezes em -confronto direto, nestas páginas. Num mundo afogado pela informação, Gleick realiza o duplo trabalho de arqueólogo e pensador. Seguindo fios soltos e pistas, alguns lançados milênios atrás, ele conecta ideias e expande horizontes, traçando relações às vezes tão evidentes quanto fugidias. Um estudo fundamental para uma era cada vez mais conectada e cada vez mais distante de si.

About the author

James Gleick (born August 1, 1954) is an American author, journalist, and biographer, whose books explore the cultural ramifications of science and technology. Three of these books have been Pulitzer Prize and National Book Award finalists, and they have been translated into more than twenty languages.

Born in New York City, USA, Gleick attended Harvard College, graduating in 1976 with a degree in English and linguistics. Having worked for the Harvard Crimson and freelanced in Boston, he moved to Minneapolis, where he helped found a short-lived weekly newspaper, Metropolis. After its demise, he returned to New York and joined as staff of the New York Times, where he worked for ten years as an editor and reporter.

He was the McGraw Distinguished Lecturer at Princeton University in 1989-90. Gleick collaborated with the photographer Eliot Porter on Nature's Chaos and with developers at Autodesk on Chaos: The Software. In 1993, he founded The Pipeline, an early Internet service. Gleick is active on the boards of the Authors Guild and the Key West Literary Seminar.

His first book, Chaos: Making a New Science, an international best-seller, chronicled the development of chaos theory and made the Butterfly Effect a household phrase.

Among the scientists Gleick profiled were Mitchell Feigenbaum, Stephen Jay Gould, Douglas Hofstadter, Richard Feynman and Benoit Mandelbrot. His early reporting on Microsoft anticipated the antitrust investigations by the U. S. Department of Justice and the European Commission. Gleick's essays charting the growth of the Internet included the "Fast Forward" column on technology in the New York Times Magazine from 1995 to 1999 and formed the basis of his book What Just Happened. His work has also appeared in The New Yorker, the Atlantic, Slate, and the Washington Post.

Here's an advertisement I want to place on craigslist because of this book:


Desperately Seeking:
Scintillating conversation partner who is preferably a math, physics, or logic major with strong knowledge of Quantum Physics and Information theory (of today and yesterday)and concepts including, but not limited to, the Babbage/Lovelace Difference Machine, Claude Shannon's math and entropy and cryptology, Turing's machine, logcal paradoxes, Maxwell's demon,The Heisenberg Uncertainty Principle, Schrodinger's cat, Richard Dawkins' memes, Goding's proofs, Douglas Hofstadter's EVERYTHING. Lack of arrogance and condescension toward someone who almost failed high school math a must. Must be willing to meet in heavily populated public place.

* * * *

Aside from that, delving into mathematics as James Gleick tells it (algebra, calculus and Boolean logic, mostly ---A watered down version for us math scarred) makes me want to write a letter to every godawful mediocre monotone high school math teacher I ever had (so, all of them) and give them some major shit for not even bothering. Really? Overhead transparencies of meaningless equations and word problems involving trains and lots of bland white kids was all they had? Worksheets and odd numbered problems in a textbook? If I had only known that math is just another way of describing the world, just, ya know, symbolism like Dostoevsky used, but with numbers, and that all that misery and embarrassment and boredom working equations at the blackboard could actually get me closer to the secrets and meaning(s) of life...So, thanks to James Gleick for that too- late realization and doing what the uninspired mathbots should have done years ago. (Are you available for tutoring?)

The Information is by no means an easy read, but if you have some previous knowledge of physics(mine came from having read Brian Greene's Fabric of the Cosmos: Space, Time and the Texture of something or other and a biography of e = mc2 but I suspect a bit of patience and wikipedia would also be just fine), you should be able to get through this without any major confusion.

Anybody wanna talk physics and Information theory?

[Yothgoboufnir · Rating 3 out of 5]

The Information has a lot going for it. And it has a lot going against it.

For starters, Gleick keeps the read enjoyable with his strong prose style. The author controls the pace and tone of his writing to carry readers along almost cinematically. Indeed, many passages read like the voice-over of a History Channel program, while simultaneously conjuring for readers the images that would play under the voice-over. It is a strong effect, engrossing and enjoyable.

The other big strong point of The Information is how wide-ranging -- yet unified -- its topic is. Gleick has, rather conspicuously, rounded up a huge catalog of sources and influences and subjects. I believe if a person is really going to like this book, it will be as an exuberant, unregimented romp through the jungle that is information. The book is ambitious, and looks at the world with the wide eyes of delight ... not the furrowed brow of calculation.

And given this combination of the book's ambition and approach, from The Information emerge some weaknesses. The book's treatment of its various subjects is very uneven. Gleick does a good job of impressing on readers how big a shift in mindset literacy generates. He gives an engrossing treatment of talking drums, and he gives an equally engrossing treatment of Charles Babbage and Ada Byron. These subjects together form an informal "first half" of the book, and succeed in prompting readers to think through the genesis of information as something (first) represented and (eventually) manipulated in tangible forms like scripts, tones, and gears.

Since we today generally take for granted a certain relationship between information, our minds, and our instruments, it is a major accomplishment that Gleick gets us to note that we haven't always lived this way and to think through how we got this way.

But after Gleick accomplishes this in the first portion of the book, he falters. His treatment of most subsequent topics is often not cogent. For example, in his treatment of thermodynamic information, he equivocates on what Maxwell's Demon is or isn't, and whether it exists or doesn't. Gleick ends up noting that the demon could not operate, but then he keeps referring to it as if it really does operate, a (presumably) rhetorical move that is pointless and incoherent.

Later on, Gleick gives a treatment of both genes and memes that is strangely uninspired. The fact that the book's wide scope requires the treatment of any particular topic to be fairly shallow does not combine well with the fact that almost everyone these days has a passing familiarity with both genes and memes: Gleick says no more than "the educated layperson" already knows. In a book on The Information, it seems genes and memes must be discussed as a matter of course -- but these sections don't add value to the book.

Moreover, the section on genes was even more deeply flawed. Gleick attributes to Watson and Crick the elucidation of the information content of DNA. He thereby conflates the chemical structure of the DNA molecule with the information structure of the DNA code. This is analogous to saying that the first person who figured out that a charred stick could be used to make marks on slate was the person who figured out writing. Or, it is analogous to saying that the information content of enigma-encrypted Wehrmacht transmissions was retrieved not by the codebreakers at Bletchly Park but by the radio operators who determined what radio frequency the messages were broadcast on. This is a rather profound mistake, considering the subject of The Information.

And this major mistake cropped up again and again, in different contexts. Despite his attentiveness to the father of information theory, Shannon, Gleick never got around to explicitly saying what makes something information, nor did Gleick implicitly follow any solid definition of information. This becomes problematic toward the end, where Gleick wants to unify everything under quantum information -- "it from bit" -- with the entire universe as a collection of physical-informational states. That is an interesting concept, but it actually has little to do with "information" as treated in the rest of the book: alphabets, calculators, cyphers, telegraphs, genes, Wikipedia articles. In all these contexts, something is informational when one physical object stands in for something else -- say, AAG for lysine, or dot-dot-dot for s. Gleick seems aware of this special relationship that defines information (per Shannon), but never pursues it and eventually abandons it. The sense of "information" he ends with is simply the notion that at certain levels, such as the level of quarks, the objects of study are indistinguishable from the formalisms by which we know them. That's a deep topic, but it isn't really pursued for its own sake; it is deployed as a rhetorical way to make "everything" informational ... even though it's only nominally related to the informational topics discussed in the rest of the book.

I found it intriguing that, in the final chapter, Gleick mentions in passing a perfect 1:1 map of everything as suggested by Lewis Carroll. Carroll was quite witty and this map is, of course, absurd. Its absurdity is precisely the problem that arises when Gleick conflates his two kinds of information. A perfect 1:1 map of everything A) would not be a map and B) would not be the thing itself.

So there were some deep conceptual problems plaguing The Information. Relatedly, the book lacked form. It was sprawling, and attempts at unification (aside from leading Gleick to embrace absurdities and forget what information even is) fell flat. As Gleick reminds us at the end in his excellent prose, there is a lot of information on the internet, and a lot of particles in the universe -- not exactly a parting thought that leaves readers pondering.

Finally, the references are in such bad shape that they warrant comment. None of the main body text has citations of any kind. Multiple times, I looked up authors who were quoted and found no entries in the bibliography! There is a section of "notes", which appears to be a collection of endnotes containing citations and comments, presumably for the many unsourced quotations in the book. This section is puzzling, because the text does not actually refer to any notes. I infer that the numerals which signal there is an endnote pertaining to some point in the text have all been removed from the book, but the notes themselves retained. Presumably the in-text designation of notes was removed to make the text appear readable rather than intimidating. A rigorously sourced book suggests to readers it is meant to be taken seriously; apparently it was decided that that would send the wrong impression for this book.

-

Bottom line:
The Information was fun and interesting. The first half was especially strong, even illuminating. But there were also serious conceptual and formal problems that prevented the book's content from matching the potential of such an ambitious topic. The book is much more likely to reward casual reading than serious or repeated reading.

[Trevor · Rating 4 out of 5]

I think this is perhaps as good an introduction to information theory as you are likely to read. Lucid, clear and quite nicely paced, it covers a wealth of material and it does so with beautiful ease. This guy really is a wonderful science writer. His Chaos and Newton were both stunning books. I got about half of the way through Genius, but then got distracted and never quite made it back – but I’ve always meant to. All the same, this one shines and shines.

Perhaps the best chapter was the one on randomness. Randomness is such a tricky concept, but oddly, not something we generally really think about. Just how do you go about proving that a series of numbers is, in fact, random? The problem is that we humans are hopeless at spotting randomness. This is partly because we are such excellent pattern picking machines that we even spot patterns when there are none. And then we also tend to think there must be a pattern if there is repetition, but random sequences have odd repetitions too. All this means we tend to think things that aren’t random are in fact random and vice versa.

The definition of randomness is that there is, in a string of numbers, a one in ten chance that you will be able to pick the next number in the sequence – in a random series you will have a one in ten chance – if you can do better than this chance at picking the number then you must have an algorithm to help you pick the next number and that means the next number can’t be random.

His discussion of Turing, not just his test but also his machine and incalculable numbers, is highly readable and clear. His discussion of Gödel is somewhat less clear, but than I’m yet to have read a perfectly clear description of the incompleteness theorem – which might say more about me than it does about the descriptions I have read, who knows. This one is still good, even if it remains over my head. However, there is a wonderful discussion of the relationship between information and entropy and why entropy is an important concept for people to understand, as good an explanation as any I have ever read.

The early parts of the book are a joy. The stuff about the barbed wire telegraphs is particularly fascinating. As was his explanation of why multistorey buildings needed the telephone to be invented as much as they needed lifts.

I was less impressed by the discussion of memes, but mostly because I don’t find this nearly as useful a metaphor as others do and worry when ideas that are clearly meant to be provocative end up being taken much more seriously than they warrant. Selfish genes and selfish memes, with their characteristic inversion of common sense, tend to become Blackmore’s ‘self-plex’ and the end of human freewill and identity and therefore take a joke all a little too far.

The discussion at the very start of this book about African talking drums is virtually worth the cover price alone. I had never realised that these communicate ‘tonally’ and that to make them work the drummer must add lots of redundancy to the message, almost like a convention of sub-phrases. This was a wonderful description of why redundancy is necessary to messages and said interesting things about Western racism. Westerners simply could not believe these drums actually could send messages or that they were not being sent by a kind of Morse Code.

This book really is a pleasure and on a fascinating topic that is deftly handled by one of the best science writers alive.

The Information: A History, a Theory, a Flood is a book written in 2011 by James Gleick

What the telegraph accomplished in years the telephone has done in months. One year it was a scientific toy, without infinite possibilities of practical use; the next it was the basis of a system of communication....

This is a fascinating science book written in a historical narrative format about the topic “information”. Today information theory is a practical and vital study spread across three disciplines: mathematics, computer science and electro-magnetic communications. Gleick addresses all these areas and then some.

In fourteen chapters, Gleick begins with cuneiforms and ends with CD-ROMs. There is very little that one can love about these bookends so you should be dissuaded from putting the book down after the first chapter or two.

Because it’s the middle chapters, four through nine, where Gleick does a masterful job. In these chapters he provides both the science and biographies of the two giants in information theory: Charles Babbage b. 1791 and Claude Shannon b. 1916.

Babbage, an Englishman, was born a century ahead of his time with his many inventions but his most relevant one to this book was his difference engine. It was a mechanical computing device that thought of numbers as bits. It predates the first vacuum tube computers used in WWII by more than a hundred years. Babbage was very much like Thomas Edison who would come along about forty years later. Babbage was an indefatigable inventor and his mind knew no bounds.

Claude Shannon meanwhile, amongst his many discoveries over decades of working at Bell Labs, is considered the father of modern communications. Shannon was the first to think of entropy as a measure of information. He was able to represent any communications system as a transmitter, receiver and interference source. With a certain level of interference he determined that it is was possible to tell the theoretical capacity of a system, i.e. he could determine the theoretical maximum bits of information that could be sent and received in any system model. This maximum is known as the Shannon Limit. These discoveries led to further exploration in the field of error encoding and so on.

Neither cellular networks nor the physical internet would exist today without Shannon’s insights. It can be argued that Shannon was not a hundred years ahead of his time like Babbage or Einstein, but it can also be argued that Shannon’s findings have transformed the world more than any individual in history. Odd as that sounds it is probably true.

5 stars. For the middle portion of this book I would assign six stars. Gleick does an exemplary job of humanizing these men in addition to providing concise and interesting descriptions around the science of information theory.

In a word I was enraptured.

[Mara · Rating 4 out of 5]

The amount of information (pun acknowledged, but not intended) that James Gleick was able to contain in the book is mind-boggling ( Claude Shannon could probably tell you what the physical cost of the logical work my mind did while reading it was, but I, alas, cannot).

I'm sure that for those who are well-versed in information theory, some of his omissions were glaring and seemingly arbitrary, but there is nothing wrong with a book that leaves you wanting more and feeling sufficiently motivated to go out and find it.

The Information , with all that it contains, is a likely candidate for the list of non-fiction books I loved, took copious notes on while reading, and would recommend, but fail to review because there is just so much to be said. However, it's Ada Lovelace Day , and without Gleick I would have no clue as to who she was (and she was awesome).

My lack of time and in-depth knowledge of Lovelace suggest that my attempt to describe her right now would be inadequate, so I'll just recommend a nice New Yorker article “Ada Lovelace, The First Tech Visionary” (and/or any of the ALD features that are bound to grace the interwebs today).

[Piyush Bhatia · Rating 3 out of 5]

Informative, but over-detailed.

The book traverses the genesis of the present information age and is a scintillating explanation of the information theory. From the definition and a cogent explanation of randomness to Claude's theory of Communication and then to data compression and error correction, the book covers a wide range of Information theory topics. But then, I still believe that some topics were quite exhaustive and require a simpler understanding, but they are made complex in the book.

I'd love to give this one 4 stars, but the complexity thing makes me give it 3.

[Jenny (Reading Envy) · Rating 4 out of 5]

I have a soft spot for mathematics. The more complicated and obtuse it gets, the more I like it. It is probably best I didn't figure this out earlier in life, because I might have pursued it and gone crazy. So I enjoy reading about it from time to time.

In The Information, Gleick speaks to the interplay between mathematical progress with science, culture, information theory, and really the development of society. It is an incredible overview of topics ranging from logic to communication to memes. It is DENSE. I spread my reading over a few weeks, a chapter here, a chapter there. When the information started going over my head, I gleefully skimmed it until I could sink back in. The formulas meant very little but then he put musical fragments into it with no explanation, and at least I understood those.

The chapter that first captured me detailed the history of the OED. I loved the logic chapter, talking about Boole and his contributions, someone very important to library theory and I never really knew anything about where all of that came from. It was the last chapter, as well as the epilogue, where Gleick steps beyond his thorough research to offer a few opinions on the direction of information and information overload, that I think the book really shines, or at least, where it was most interesting/useful to me.

I don't know enough to speak to the accuracy of this book, but I feel like I learned a lot, as well as adding a bunch of other books to read to my list that he cites. I will also be ordering it for the academic library where I work, and using it in a presentation I'm giving in February! Win/win/win.

"It sometimes seems as if curbing entropy is our quixotic purpose in this universe."

"We make our own storehouses. The persistence of information, the difficulty of forgetting, so characteristic of our time, accretes confusion."

"When information is cheap, attention becomes expensive. For the same reason, mechanisms of search - engines, in cyberspace - find needles in haystacks. By now we've learned that it is not enough for information to exist."

"Too much information, and so much of it lost. An unindexed Internet site is in the same limbo as a misshelved library book. This is why the successful and powerful business enterprises of the information economy are built on filtering and searching."

"Infinite possibility is good, not bad. Meaningless disorder is to be challenged, not feared. Language maps a boundless world of objects and sensations and combinations onto a finite space. The world changes, always mixing the static with the ephemeral.... Everyone's language is different. We can be overwhelmed or we can be emboldened."

"We want the Demon, you see,' wrote Stanislaw Lem, 'to extract from the dance of atoms only information that is genuine, like mathematical theorems, fashion magazines, blueprints, historical chronicles, or a recipe for ion crumpets, or how to clean and iron a suit of asbestos, and poetry too, and scientific advice, and almanacs, and calendars, and secret documents, and everything that ever appeared in any newspaper in the Universe, and telephone books of the future.'"

"As ever, it is the choice that informs us... Selecting the genuine takes work; then forgetting takes even more work."

"The library will endure; it is the universe... We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information."

[David Wiley · Rating 5 out of 5]

Only half way through this book but it's one of the best I've read in a very long time. The chapter on Babbage and Lovelace filled me with rapture and awe, and a little bit of jealousy, peeking in on these great discoveries and the heady conversations and frequent advances and discoveries. What must it have been like to work at that level, to discover those things, to be so far ahead of your time? Incredible writing, so well researched, I just love this book... And as a bonus, highly applicable to my day job!

20th book for 2018.

In my doctorate I read and enjoyed many of the original 1950s papers applying information theory to psychology. I read Gleick's Chaos: Making a New Science many years ago and loved it, so his history of information was a natural second book for me to read.

Although his writing style is good, the book was quite disappointing. The book simply covers too many different topics with little to connect them (African drums; the telegraph; encyclopedias and dictionaries; codes; Babbage and Lady Lovelace; information theory; quantum computing; Wikipedia, encyclopedias again). While the chapters are interesting in their own way, nothing really adds up into something more coherent.

Not a terrible book, but it could have been so much better with a tighter focus.

3-stars.

[Jimmy · Rating 4 out of 5]

The history of information theory is a history of increasing abstraction. To the point where the meaning of information becomes irrelevant. To the point where the universe itself can be seen as a giant computer, and each of our choices, thoughts, movements become like states in the machine. I loved reading about the African drummers who communicated over long

distances via a tonal drum language with built in redundancy. I loved reading about Babbage and his calculating machine, and to think about it as a kind of steam-punk calculator fantasy world of the future. I loved reading about people decrying the telegraph and the telephone as technologies that will ruin humanity. And to read about the shortening of telegraph messages to save time and money, with phrases like wyegfef which stands for 'will you exchange gold for eastern funds?' which is interesting because here we are in 2012

coming full circle, a form of regression maybe, by using codes like ROFLOL and BRB in our chatboxes and cellphones. And also that the telegraph reminds me a bit of twitter in its shortness. I didn't love reading about Godel and Turing and Shannon, but only because I've read so much about them already in other books just like this one, but it was still interesting enough. I liked reading about genes and the gene code ok, but I really loved reading about quantum computers because I knew next to nothing about them. Something I never thought about before is how a message sent using a quantum computer cannot be intercepted or wiretapped because of Heisenberg's principle

which says that you can't look at a quantum particle without effecting it, so in effect the intercepter cannot go undetected! This blew my mind. I loved reading the more philosophical chapters about how we have too much information for us to ever process, and how we must now deal with it. I loved reading about the library of babel and borges of course, how could I not? I loved thinking about how we have too much information and how everything is documented. "It did not occur to Sophocle's audiences that it would be sad for his plays to be lost; they enjoyed the show". I thought about that and I thought

about how every performance, ceremony, or event that I've been to in the last year or so has been recorded on video (and probably up on YouTube already) and how or whether that took away from the experience, whether knowing something will be archived later makes you pay attention less now, or is it a form of insurance, a kind of just-in-case, which then made me wonder how many times I (or anyone) will ever go and watch those videos again. I thought about the last chapters and how Google and other search engines are our only means of not being completely lost in meaningless data and then I thought about how much power the role of a search engine is, to make sense of the information is also to hold all the power, to control the information, to control what information people see or don't see. I'm looking forward to the sequel.

[David Rubenstein · Rating 4 out of 5]

While nothing in this book is really new, Gleick has managed to pull together a fascinating, comprehensive review of the subject of information. The book does an excellent job unifying a vast subject area. I appreciate the book's emphasis on the contributions of Claude Shannon to the field of information theory. Also, it is eye-opening to be reminded, that an animal's body is simply the vehicle that a gene--i.e., information--uses to self-replicate. And it was fun to learn about earlier methods of long-distance communications, like jungle drums and the semaphore system used in France. I would recommend this book to anybody who uses his brain to store information.

14 cd's as a audiobook. A good book with alot of trendy topics that would be of interest to the Wired and Neil Stephenson crowd. Maxwell's Demon,The entropy of information, codes,Goedel, Turing, Babbage, Ada, how new forms of new information technology: printing, the dictionary, telegraph, telephone, television changed things. I found it clearly written, fun and interesting.

I would like to have given it 4.5 stars.

I begin by saying to my middle school algebra teacher, “Damn, why didn’t you just say so?” At the risk of revealing my age, I can tell you that mathematics as taught in my elementary school era certainly lacked certain clarity in the fact that rote memorization played a totally unnecessary role as far as I was concerned. Luckily for me, I knew how to manipulate money long before I went to school, so the patterns in math were already obvious. Then suddenly there were these little xs and ys and I was completely thrown for a loop! “Why are these letters slinking around with my beloved numbers?” I thought. Gee, I wish my teacher had just given me Charles Babbage to read. After the initial shock, the patterns that I knew so well did return and I moved on, loving algebra, but the process would have been so much smoother had someone simply told me to think of the “x” as an empty box waiting for the right number to complete the pattern!

I am not a math and science whiz by any stretch of the imagination; I am, however, in awe of both and always have been. As far as I’m concerned, it takes a bazillion times more creativity to discover and prove a math or science concept than it does to write a story or poem. Literature is limited by the human experience and needs no proof. Math and science have no limits—think universe and ∞—and if you are unable to prove your theory, you will not become a part of the conversation unless, of course, someone else can prove your theory.

The Information, as I see it, is about just that, extraordinary people seeing the patterns first, forming a theory, beginning their proofs, and others building on those proofs until new understandings emerge. It’s an exciting and wonderful journey!

If you are the type of person that must understand and see clearly every concept mentioned in the book you are reading, don’t pick this one up. (Although, I’ve never understood why people who can read Oscar Wilde or T. S. Eliot comfortably can become so uncomfortable reading a book like Mr. Gleick’s that they would put it down and consider it too difficult to understand.) I have a high tolerance for the vague; it doesn’t bother me. There is a lot in this book that is vague to me, but I was constantly rewarded with so many “Ah ha!” moments that it did not interfere with my total enjoyment.

For example, how do you write about a theory before there are clear and concise words to describe it? Words that everyone can agree upon must first be written about. “...where Newton wanted words for nature’s laws, Wittgenstein wanted words for words...” The limitation of words is that you must use words to describe them! Did you know that your teenager wasn’t the first to use expressions such as “lol” and “bff” to communicate? I did not, but when telegrams were charged by the word, people adapted by doing exactly the same thing—see page 154. Then there is the redundancy in language factor demonstrated nicely by one of my favorites, the James Merrill poem and 1970s subway sign “If U Cn Rd Ths, u cn gt a gd jb w hi pa.” “Bit” is a combination of binary and digit. Duh, but I truly did not know this!

Near the end of the story, we go from bits to bytes, to megabytes, gigabytes, terabytes and I found myself reading faster and faster and... as if experiencing the John Lanier quote, “It’s as if you kneel to plant the seed of a tree and it grows so fast that it swallows your whole town before you can even rise to your feet,” up close and personal. (Reminds me of The Blob and Invasion of the Body Snatchers.) We’ve moved from an oral culture where words/impressions were dissipated/forgotten or changed down the line—like kids sitting in a circle playing the game Telephone—to terabytes+ of the same set in code and then disseminated exponentially through our technology. Personally I like that idea; it doesn’t scare me at all. Can you tell? I loved this book!

Since I was absolutely astonished by such Gleick works as "Chaos" and "What Just Happened", and since his subject matter (Claude Shannon, Godel, info theory) is right up my alley, I was prepared to give this book five stars, particularly given raves in NY Times Book Review and elsewhere. Quite honestly, I'm tending toward the Goodreads consensus of four stars, leaning to a high three. And the reasons for that are quite specific.

Gleick pulls all the right ingredients together - Charles Babbage, Lady Ada Lovelace, Claude Shannon, Alan Turing, Kurt Godel, Norbert Wiener. He gives us unique quotes from Lady Lovelace's letters, odd anecdotes of Shannon and Godel meeting at Princeton. The book is lively and readable for the most part, though the odd algebraic algorithm might scare some people. And yet, and yet.... Something feels like a perfectly prepared pudding or souffle that wasn't cooked at the right temperature, leading to a failure to set properly.

Perhaps the problem is that Gleick set a high bar for himself with "Chaos", and a high bar was set for incompleteness theorem and information with Douglas Hofstadter's "Godel Escher Bach: An Eternal Golden Braid." Gleick quotes at length from Hofstadter, to be sure, but he doesn't achieve quite the sense of astonishment and whimsy that Hofstadter did when GEB first came out in the early 1980s. Maybe I was expecting Gleick to provide a new theory of what happens when incompleteness meets infinite recursiveness meets the compressed-code condition where a single symbol stands for a universe of meaning. Maybe that was a ridiculous expectation.

This book makes a wonderful companion to Hofstadter's GEB, William Gibson's "The Difference Engine", and similar works. It makes Shannon and Turing seem like real people, though it does not delve into the heartache of Turing's persecution as a homosexual, which several biographies of Turing have done. Gleick ends the book with a marvelous treatise on Wikipedia's reason for being in this world, and a suggestion that we are running into a new recursiveness when an ever-expanding Wikipedia begins to stand for all sentient knowledge in the universe - have we gained anything in library management or data compression? Still, Gleick manages to end the book on an optimistic note, not wringing his hands too anxiously over information overload, etc.

Remember, a pudding or souffle that comes out of the oven a little too runny still can make for good eating, and Gleick's book is often yummy. Just don't expect "The Information" to reach new frontiers of information theory. It's just a dime map of the reef, and that's OK.

A wonderful and eclectic book that gave me a new perspective. I'm not sure how this book reads for those already versed in information theory - I think it's largely designed for those who are not - but it's a great introduction to the subject.

Gleick is especially got at illustrating how wide-ranging this subject is, and how innovations from people like Claude Shannon or Alan Turing rippled out into fields as diverse as linguistics, genetics, and psychology. It's rare that an introductory book can legitimately offer a slightly different way of viewing the world while still remaining grounded and accurate, but this work pulls it off beautifully. I'd love to read more on information theory if anyone has any recommendations for me.

In all of science there lie deep and irresolute fissures that necessitate the existence of many mutually exclusive domains of knowledge. Each with its own lexicon, icons, dogmas, turfs to defend and legacies to uphold. Each operating relatively independently with little communication with or interest in what goes on outside their four walls.

Knowledge, however, is not fragmented. The natural world exists as a whole with there being no inconsistencies in the entirety of the observable universe. Human understanding of it, sadly, is anything but complete. No matter how much we advance as a civilization, as a species, we can only sing to the rhythm set by nature. The so called "laws" of nature are nothing but patterns discerned through observations and contemplations. But nature itself doesn't obey any laws. These exist for our comfort. And if it happens, as it has happened many times, that nature seems to "violate" the laws, our discomfort compels us to create better laws. Laws that are more satisfactory, more comforting. The natural world is an unending mystery.

Science is just one of the ways to understand nature. It is arguably the best way. But even science doesn't have all the answers. It is subjectively elegant and delicate though. There lies an inherent beauty in the simplicity of its systemization. A heady ephemerality that is often missed by those who prostrate at its altar. Worship of science defiles its method and thus destroys in essence what is being worshipped.

The book in question travels far and wide across space and time and takes the reader through disciplines that hardly anyone would have more than a slight familiarity with. But even though these subjects range from theoretical and physical sciences to psychology and even humanities, the effect in this book is always harmonious and conjoint. The waves created by the information theory reverberated back and forth between numerous disciples and even the past and future.

There are more than a few things here that flew right over my head. Such as quantum physics. Anything quantum for that matter. My training in engineering had exposed me to classical mechanics in some depth and I had the inquisitiveness to plough through relativity on my own. But anything quantum just doesn't get digested. The last part of this book deals with entanglement and its implications for quantum computing and it was a most difficult part to read. But the remaining four-fifths of the material is fascinating as well as understandable. It is remarkable to view old topics in the new light of information: thermodynamics, evolution, genetics, numbers, linguistics and behavioural psychology to name just a few. In my humble opinion a mere moment of realization is reason enough to read a book. And this book offers dozens of those.

This book was very interesting. It seems to be a history of information theory, and the author weaves together strands from a number of different disciplines, bringing to life what could be very dry. But once I'd finished it, I felt somewhat disappointed. I felt that he gave very short shrift to the internet, despite some interesting sections on wikipedia. How can you write a book on Information and not spend a good part of it discussing the internet. Of course, I'm a techie, so I'm somewhat biased, but I felt a little cheated.

Also, after I finished the book I felt a little bit of "So?" If he was trying to make some kind of point, I'm not sure I got it. Despite that, I think it's worth reading, for the historical perspective if nothing else, just don't expect life-changing, or even thought changing, revelations.

[Melissa · Rating 4 out of 5]

If you like the idea of relating information to thermodynamics - more specifically, the second law of entropy, you will whiz through this book in one sitting despite its length. In any transformation, a dissipation occurs. Loss in one form of energy is inevitable; in our futile attempts to avoid this loss, we inadvertently gain energy in other forms. Information can be viewed similarly. As it travels through books, mouths, films, etc., it loses something each time. This loss creates room for the unintended lessons.

I probably slaughtered the description with my futile attempts at explaining this – suppose that conveniently serves as further proof of the validity of his message.

A sprawling hodge-podge. Ranging over a variety of subjects, even if they are only loosely related, is fine if done properly; making a stew of arcane details and an avalanche of quotations is not. Any one interested in the individual subjects mentioned in this book (e.g. cryptography, quantum computing, communications theory) would be better served to find books particular to these areas. There was just barely enough interesting material in the book to merit 2 stars.

[Carlex · Rating 5 out of 5]

Since my student times (in times of the Austro-Hungarian empire, more or less) I was fascinated by the information theory and now I wanted to know more about it. This book meets all my expectations, so ... five stars!

[Brian Clegg · Rating 5 out of 5]

A new book by James Gleick is a much-anticipated thing. Admittedly he hasn't always lived up to the promise of his excellent Chaos, but most of his books have been top notch.

In The Information, Gleick gives us a full bore account of the defining feature of our age. We explore the nature of information, how it has been communicated from the written word and jungle drums through to the internet, and, perhaps most fascinating of all, Gleick takes us through the social historical impact of a burgeoning quantity of information. It's fascinating that the whole idea of information overload was first brought up not as a result of the internet, but hundreds of years earlier as a response to the flood of information that the printing press released on the world. And then again for microfilm.

Rather oddly for someone who has made their name as a science writer, Gleick comes across best in the social history sections. The more detailed the science, the more he loses us. In part this is down to the Claude Shannon effect. Shannon is an absolutely central figure in information theory, and yet every book I've ever read that featured him gets dull when he is mentioned. I don't know why, exactly, but Shannon is like one of those people at parties who can be talking about the most exciting subject and yet make it depressingly boring.

You can't write a book like this without having a lot of Shannon turning up, but it does make it difficult for the writer to keep the reader's attention. I also thought that Gleick could have made more of the whole 'it from bit' cosmological theory - it comes across very vaguely, without the scientific backing you might expect. But there is so much more to enjoy, whether it's one of the best accounts of Babbage and Ada King (not Lovelace) and the emerging concept of computing, or Turing's work, or telegraphy wireless and otherwise. It's a rich (if not always well-structured) concoction of information about information.

There's so much information in there, you suspect that Gleick's research was occasionally a bit thin. So, for instance, he refers to the transistor pioneer William Shockley as an Englishman. Shockley was an American, brought up in America. The only reason I can imagine anyone calling him English is that when you glance at his Wikipedia entry (and yes, Wikipedia gets a fascinating write-up in the book), it jumps out of you that he was born in London. Read a little further, though, and you'll see this is just because his American parents happened to be there at the time.

I do also have a couple of small issues with this book as a whole. Firstly it's a doorstop. I seriously dislike books this thick, and it's a mark of how good the good parts are that I put up with a 526 page tome. There are a couple of chapters that could be done away with entirely, and there's a lot of unnecessary flowery text. The other issue is that it can stray a little into the pretentious. This comes across perhaps most strongly in the title - putting 'The' upfront feels very calculated.

However, The Information does squeak in as a five star book, partly because the subject is so central to twenty-first century civilization (I find it difficult to think of a day when I haven't used the internet or touched a book) - and partly because when Gleick's writing is going brilliantly, which is for well over half the book, he is compelling to read. This is a truly interesting book, even if you may have to skip a few bits to get through it. And it is one you ought to have on your shelf. (Just make sure it is reinforced first.)

As a kid I loved to read the books on science by Issac Asimov.

I once had a job (1977) as a night janitor at a telephone switching office - back in the day when there were real live operators on duty for directory assistance, etc.

After finishing up my duties - cleaning ash trays, emptying wastebaskets, I would go to the basement, pull up a chair by the huge array of batteries that (still) provide backup power for the wired telephone system and read Asimov explaining the structure of the atom and how electricity works. I couldn't get enough of how things worked.

James Gleick follows in the Asimov tradition as a science writer for the masses but he gets in pretty deep.

The book is divided as the title describes into three sections - one about the history of information, one about the theory that developed to explain it, and finally a look at the flood of it that we are now experiencing. Throughout is that wonderful sense of excitement, discovery and adventurous thinking that Asimov was so good at relating.

There are many remarkable things in this book, one of which is an account of how writing changed the way we think from what it had been before. A different mental operation is at work when you relate things aurally, about things that you have seen, than when you write in symbols that bring up concepts that cannot be physically experienced. Also mentioned is the fact that writing is not evolutionary - in the sense that stone-age humans would have been able to write if they were instructed; The potential has been there all along. This kind of thing makes me eager to turn every page for more.

When Gleick gets into the theory of information even more fascination awaits. What is the information content of a printed character, of a dot or a dash of Morse code, of a photo? Much thinking went into analysis of communication before Claude Shannon came up with a formula for specifying the amount of information precisely - it has to do with novelty, unpredictability, and complexity but is completely independent of the meaning we place on communication. Now do I have your interest?

But things get deep. Here is an example from where I got completely lost...

" 'Feynman's insight,' says Bennett, 'was that a quantum system is, in a sense, computing its own future all the time. You may say it's an analog computer of its own dynamics.' Researchers quickly realized that if a quantum computer had special powers in cutting though problems in simulating physics, it might be able to solve other types of intractable problems as well."

Have you got that? Fortunately, the book doesn't often get this deep and right after the above quote the author leaves the theory for the flood section - much easier to swallow!

So step right up and challenge your mind to a roller coaster ride. There will be times when you will s-l-o-w d-o-w-n just as a coaster does when climbing the first height, but then you will find elation as you zoom into new ideas!

[Joshua · Rating 4 out of 5]

I enjoyed reading this book thoroughly. However, I do not think it will satisfy everyone who is considering reading it. I know many of my librarian colleagues and my classmates from the School of Information probably have this on their to-read lists. Many of them are probably more interested in contemporary issues of information management, such as information retrieval, social network analysis and human-computer interaction. This book touches some of those issues, and indeed many others, but this book is primarily about the history of information theory. The subtitle of the book is "A History, A Theory, A Flood," but the Flood part is only discussed in the final chapters. The rest of it is devoted to the theory and history.

You can tell that Gleick has spent his career writing biographies and histories of physicists and mathematicians, because those subjects are covered in greater detail in this book. The two most prominent individuals that Gleick focuses upon are Charles Babbage and Claude Shannon. If you're interested in the history of science, math and philosophy, or if you would like a good explanation of information theory (which I think most people do not understand correctly) then I would recommend this book. Otherwise, this book may not be what you are hoping it to be.

If you are into that sort of thing, then this book will be a fun read for you. I found it extremely fascinating.

A couple passages that made me pause:

An amusing quip on entropy: "Living things manage to remain unstable." Indeed. Increased entropy is the natural progression of the universe. But living things maintain an organized state, which is highly anti-entropic. Hence, we are all unstable people!

On memes: "...rhyme and rhythm help bits of text get remembered. Rhyme and rhythm are qualities that aid a meme's survival, just as strength and speed aid an animal's. Patterned language has an evolutionary advantage. Rhyme, rhythm, reason--for reason, too, is a form of pattern." This is an interesting thought. Reason as simply a pattern--a memory aid.

The library will endure; it is the universe. As for us, everything has not been written; we are not turning into phantoms. We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

The first time I saw Jurassic Park, I was surprised by the inclusion of Jeff Goldblum's character: why would the initial outsider tour of a dinosaur safari park require the presence of a Chaos Theorist? I decided his character was a popsciencey “dissenting expert” trope; “the bad boy of mathematics” being present to make author Michael Crichton look smarter than the viewer (or the reader of the original book) and to give the Paleontologists in the story someone to argue with. But in light of James Gleick's The Information, it's Jeff Goldblum in Jurassic Park that I'm primarily put in mind of: this is yet another book that I've read recently that takes as a given that the universe is simply a giant algorithm and humans are merely the machines evolved to compute it. If all of “the information” that we process can be expressed in binary digits, then all of life and all of experience is simply and purely math. As Gleick sketches out in this history of Information Theory, mathematicians have been grasping at this fact for the past century and a half, and throughout this time, there have always been Jeff Goldblum-type characters in the background, looking like lunatics while speaking the truth. If all of experience can be reduced to math, it follows that math can be used to predict experience, and ultimately, the Chaos Theorist was the most important member of the safari (helpfully reinforced in Crichton's story by having Jeff Goldblum be right about everything from the start). Today, we all benefit from the practical applications of Information Theory – with our laptops and smart phones and the dawn of quantum computing – but we should remember that in the shadows live these mathematician-philosophers who not only advance technology, but who are in effect changing the way that human brains work.

I picked up The Information after having so enjoyed Gleick's latest book, Time Travel. What I most liked about that book were the intersections Gleick created between hard science, philosophy, and literature, and that is essentially the ethos of this earlier work, too. I do not have a math brain, but Gleick was able to lead me through the equations in the history of Information Theory, and with an interesting prose style, always bring the focus back to the fascinating people behind the evolving hypotheses. While discussing information as a flood, Gleick quotes Lewis Carrol's satirical bit about the drawbacks of creating a 1:1 scale map, and that's useful for me to remember as I attempt to record all the ideas in this book that interested me; the impulse would be to copy and paste the whole thing.

Gleick begins by describing the earliest modes of faster-than-human-or-animal-conveyance long distance communication, and I was most fascinated by the idea that both African drumming (which was infinitely more rich and lyrical than later Morse Code; employing embedded redundancies much like those found later in the gene itself) and a string of bonfires are essentially both binary systems (the drums always communicated through two distinct tones and the fires were only on or off). Gleick covers the beginning of writing and the mental leap it took to evolve from hieroglyph-type pictograms to the metalanguage of substituting symbols for words and then for word-parts (which are themselves symbols). This leads to the Greek philosophers and my first wow moment: Socrates lived in a pre-writing era, and his protege Plato resisted the fad of writing down his own thoughts: warning that removing the need to remember facts would lessen our collective wisdom (and doesn't that sound familiar today?) When Plato's own protege, Aristotle, did begin to assemble knowledge in the written form, he was essentially inventing the way we now think (and I know that I could have learned, or even intuited, this before but I didn't: the reason why Aristotle was the father of all sciences and all theories of thought was because he was the first [Western] person to ever write it all down).

Logic might be imagined to exist independent of writing – syllogisms can be spoken as well as written – but it did not. Speech is too fleeting to allow for analysis. Logic descended from the written word, in Greece as well as India and China, where it developed independently. Logic turns the act of abstraction into a tool for determining what is true and what is false: truth can be discovered in words alone, apart from concrete experience. Logic takes its form in chains: sequences whose members connect one to another. Conclusions follow from premises. These require a degree of constancy. They have no power unless people can examine and evaluate them. In contrast, an oral narrative proceeds by accretion, the words passing by in a line of parade past the viewing stand, briefly present and then gone, interacting with one another via memory and association.

Because of Aristotle, we are now people who think in terms of categories (proven to be true even for illiterate people in a literate society; a trait not found in nonliterate societies), but it wasn't until the invention of the printing press that knowledge became standardized.

Thomas Hobbes, in the seventeenth century, resisted his era’s new-media hype: “The invention of printing, though ingenious, compared with the invention of letters is no great matter.” Up to a point, he was right.  Every new medium transforms the nature of human thought. In the long run, history is the story of information becoming aware of itself.

Not long after Hobbes came Newton, and while I did know that he invented Calculus and ignited the Scientific Revolution in England, I knew but hadn't really appreciated that Newton also invented the language of Physics; being the first to use terms like “mass” and “force”; pretty much doing for math what Aristotle had earlier done for written language. The next parts that I found interesting involve the evolution of long distance communication, and especially the telegraphy towers – looking somewhat like windmills, they spoke a type of semaphore that could be seen and relayed from tower to tower – which was the height of communication right up until it wasn't: with the advent of electrical telegraphy and Morse Code, which was the height of communication right up until it wasn't: with the advent of telephones, which were the height...And in the background, there are all these mathematicians, looking like lunatics while speaking the truth, and I especially enjoyed the image of Charles Babbage and his steampunk computer, and his contemporary, the Lady Ada Lovelace (illegitimate daughter of Lord Byron and, like Babbage, a genius thinker born before her time; forced to express her mathematical insights as philosophy because technology hadn't yet caught up to her vision). Imagine the first dictionary needing to begin by explaining what is meant by “alphabetical” and how to use the system to find entries within the book itself. With the turn of the twentieth century, I was fascinated by Gödel's incompleteness theorem, Maxwell's Demon, the Turing Machine, Wiener's Cybernetics, Claude Shannon's Information Theory, and Richard Dawkin's selfish gene; for what is a human if not a means for a gene to transmit its information?

The macromolecules of organic life embody information in an intricate structure. A single hemoglobin molecule comprises four chains of polypeptides, two with 141 amino acids and two with 146, in strict linear sequence, bonded and folded together. Atoms of hydrogen, oxygen, carbon, and iron could mingle randomly for the lifetime of the universe and be no more likely to form hemoglobin than the proverbial chimpanzees to type the works of Shakespeare. Their genesis requires energy; they are built up from simpler, less patterned parts, and the law of entropy applies. For earthly life, the energy comes as photons from the sun. The information comes via evolution.

So here's the tl;dr: I have read other reviews that lay out all the ways in which Gleick is supposed to have stressed the wrong ideas or misinterpreted others, but as a primer for the history of Information Theory, I found The Information to have been an accessible and fascinating read. As a non-expert, I have no idea if I understood this book down to its bones, but I do now appreciate why Jeff Goldblum's character was in Jurassic Park.

This book could have alternately been titled "A History of the Bit: How the bit made modern communication, computing, logic, an understanding of biology and a whole bunch of other stuff possible." It's James Gleick's extremely ambitious attempt to wrap his arms around the entirety of the expansive concept of "information." To the uninitiated, "information" might seem like a rather straightforward concept, unworthy of a 400+ page book. After all, what is there to say about a concept that we all commonly refer to, understand, and take for granted? Quite a bit, as it turns out.

The good news is that this is not another book about the history of computing, from the Gutenberg press to the Macintosh. There are more than enough books on that topic. So, exactly what is it about? It's hard to be succinct about that. It might be better to offer a listing of broad topics covered.

He starts with the most basic of communication systems: the African drum -- a method of communication over distances that surprised early european colonizers with its apparent accuracy and specificity. From here, he moves to Babbage's mechanical difference engine and the first organized thoughts about the nature of information itself. When one has to carry out mechanical computation, it seems to be universal that an analysis of what comprises information quickly ensues. A new branch of philosophy is born.

Succeeding chapters cover technologies we typically associate with the transmission of information: telegraphy and telephony. Telegraphy introduces the idea of creating one set of symbols that can represent another set. In this case, dots and dashes for an alphabet. Twenty six characters are reduced to two. Telegraphy also introduced the need to reduce even further the number of characters by which a message could be clearly received, as in representing common phrases by a series of three digit numbers. Such a reduction costs the transmitter less money to send and enables the owner of the system to send more messages in the same time, earning them more money. This is information compression in its simplest form. Sending a message through an intermediary (a telegrapher) also means that you might want to hide the meaning of the message from them. This leads to ciphers and other methods of encoding. The sender and the receiver share a common key for decoding.

Telephony reduced the barriers to telecommunication by reducing the middle man, saved money for businesses by reducing the need for messengers and increasing the speed of messages. Telephony also drove further information technology innovations. Phone companies (or THE phone company at the time) devoted considerable resources to dealing with problems of long distance transmission of voice information over inherently "lossy" copper wires. Sifting meaningful signal from distance-induced static and noise became of focus of some particularly talented engineers. Analysis of this problem lead to mathematical abstractions as they tried to reduce "information" to the lowest possible common denominator. How small of a signal can carry a message? How can "message" be defined mathematically? The idea of the "bit" became common and the field of information theory began to take off. It had existed before, but it had never flowered in the way that modern communications forced it to. Claude Shannon is a central figure in the development of modern information theory and his revolutionary ideas are quoted extensively throughout the book. Parallel developments in information theory occurred with Alan Turing who developed the theoretical basis for computing before any of the hardware existed.

Some familiar computing history themes are then covered in which Gleick reviews projects undertaken during World War II to create mechanical systems capable of shooting down fast moving aircraft from the ground. These projects produced mathematical methods for estimating random motion and predicting probabilities, problems very similar to the efforts of phone engineers to separate signal from noise.

What Gleick tries to get across is the idea that the developments in information theory, some of which are concepts that we take for granted today, are in fact not intuitive at all. The idea that all information could be conveyed by nothing more than two states, on and off, yes or no, was revolutionary. For people of the era, these ideas would be like suggesting the existence of a new color that no one had ever imagined before. Shocking, like an intuitive leap that seemed to come from nowhere.

Information theory has implications for...well, just about everything in existence. It has implications for biology. The basic units of heredity, the genes, carry a certain number of bits of information needed to describe traits. DNA molecules can be thought of as biological memory storage devices, mere transmitters of information. It also has things to say about memes, self-replicating packets of information. Gleick quotes Dawkins and wonders if they're like genes, existing to propagate themselves.

Towards the end of the book, he advances to modern developments of the past 30 years or so such as information compression and quantum information science. As part of this journey, Gleick tries to cover some very challenging mathematical topics like randomness, incompleteness theorems, the absolute computability of numbers and chaos. These sections are less successful. I got the feeling that he felt the need to include them, but felt that he could not adequately reduce them to a level that even an industrious layman could handle. Many terms are introduced which are never thoroughly explained, or which are explained tautologically, using poorly explained concepts to label new ones.

Finally, he ends with a light analysis of the cultural implications of the info-clogged modern world: information fatigue, information glut, and the devaluation of information that is ubiquitously available for the first time in history.

This is a big topic...indeed, a massive one. While "The Information" rambles on in places and seems disjointed in others, it's an important book. It brings the philosophy and science of information itself to a lay audience. Mathematicians and philosophers will be familiar with many of the concepts it contains, but this may be the first book that attempts to bring these rigorously technical fields to the masses in an easily digestible form.
