5.0 out of 5 stars
Great book, but not for everyone,
By Steve Stowers (Springfield, Illinois USA) - See all my reviews
This review is from: Everything and More: A Compact History of Infinity (Great Discoveries) (Hardcover)
I greatly enjoyed this book, but it's not for everyone. To appreciate it, there are two requirements: (1) You must enjoy, or at least tolerate, Wallace's quirky writing style, with its mixture of the conversationsal and the erudite, its frequent footnotes, abbreviations, and discursions. (2) You must have a certain level of mathematical sophistication. This is not one of those popularizations of math for those who never got past high school algebra. It could perhaps be described as a history of calculus, analysis, and set theory, and specifically of their attempts to come to grips with the infinite and the infinitessimal and make them mathematically valid. The focus is on theory and rigor--which maybe makes it sound dry, but it's not, if you like that sort of thing. It's not that Wallace himself gives lots of rigorous arguments, but that he talks a lot ABOUT the search for mathematical rigor.Reading this book is a little like sitting in on a class taught by an inspiring yet quirky professor (and, indeed, Wallace makes frequent reference to an inspiring, quirky teacher of his own). Such a class would have a prerequisite--I'm not quite sure what, maybe at least a semester or two of calculus. Probably, the more you know about calculus and related subjects, the more you'll get out of this book.

A Little Look at Infinity,
By R. Hardy "Rob Hardy" (Columbus, Mississippi USA) - See all my reviews (TOP 100 REVIEWER) (HALL OF FAME REVIEWER) (REAL NAME)
This review is from: Everything and More: A Compact History of Infinity (Great Discoveries) (Hardcover)
Have you thought about infinity recently? If so, it was possibly bound up in religious ideas, in some of which it is integral ("Where will YOU spend eternity?" says one local billboard). Religious infinities have lapped over into mathematical ideas in surprising ways, and if you hanker to do some serious reading about mathematical infinities and their history, you should consider _Everything and More: A Compact History of Infinity_ (Norton) by David Foster Wallace. Wallace is a novelist, author of the huge and well regarded _Infinite Jest_. He isn't a mathematician, except by avocation, but his enthusiasm for his subject is apparent on every page. It's a good thing that this is so; this is definitely not a superficial look at the subject, and Wallace calls upon some high-powered math that you may not even have done in college. The result is a penetrating book from a serious amateur on some of the most important ideas from nineteenth and twentieth century mathematics.Wallace starts his good-humored and sympathetic tone from the beginning: His "Small But Necessary Foreword" begins, "Unfortunately, this is a Foreword you have to read." There are plenty of footnotes, but half of them are marked "IYI": "If You're Interested," as are many of the paragraphs in the main text (along with "Semi-IYI"). In a history composed of increasing mathematical rigor, Wallace jokes and uses slang. Much of the history has to do with trying to solve the paradoxes of Zeno, like the one about how you can ever get to the other side of the street when you first have to go halfway, then half of the rest of the way, then half of that, and so on. The paradoxes were curious, but when supremely useful calculus came along, the infinitesimals used had never been rigorously defined. It was not until Georg Cantor showed how to deal with infinities as real mathematical entities that calculus had a mathematical foundation. He showed that infinities could be compared, and some infinities were larger than others. The proofs of these ideas (about one of which a mathematician said, "I see it, but I don't believe it!") gave calculus roots, but also gave rise to questions that eventually shook all of mathematics to its foundations. Wallace doesn't get much into Gödel and his eventual Incompleteness Theorem, and it is just as well. There is enough excitement here, at least exciting for anyone who finds paradoxes a charming way to make the neurons spin. Admittedly, he has included equations and propositions full of Greek letters and advanced functions that only math buffs will absorb. He says of Weierstrass's demonstration of continuity, for instance: "There's a reason this all looks so hideously abstract: it _is_ hideously abstract." The substance is tough going, but there is enough style here, in jokes, curious illustrations, and piquant asides, to make this a fascinating show of intellectual prowess.

Challenging, thought-provoking, entertaining, and disappointing,
By
This review is from: Everything and More: A Compact History of Infinity (Great Discoveries) (Paperback)
A reviewer, below, cites Zeno's Paradox as a metaphor for his experience reading E&M. This is precisely how I felt. Wallace's endlessly annoying flourishes aside, the first half of E&M is very interesting and accessible. Parts of the second half are, too, but those parts are islands in a sea of mounting incomprehensibility. Too much is left unexplained ("you'll have to trust me"-type asides, generally in "IYI" footnotes, abound) and too much else is expressed, formally, in arcane mathematical notation. Granted, Wallace's subject-matter is highly abstruse, and anything remotely approaching mathematical rigor would be both impossible in a book of E&M's size and impenetrable to a popular readership. Faced with these obstacles, Wallace makes a go of writing both to lay readers and specialists. Specialist reviewers on this page criticize Wallace for making numerous errors. As a lay reader, with a deep interest in mathematics (the practice, theory, history, and foundations of), I was (and remain) very eager to read a sophisticated (incipiently rigorous) treatment of the topic of infinity. The first half of E&M delivered a moderately sophisticated (mathematically unrigorous) treatment of the metaphysics of infinity. The second half attempted something like the treatment I had hoped for, but it was pitched entirely too high. The only hope a reader realistically has of navigating the second half of E&M is if (s)he brings a high level of mathematical sophistication to it. Such a reader, however, would almost certainly gravitate towards a genuinely rigorous treatment of the subject (like Dauben's biography of Cantor, oft-cited by Wallace). I'd like to think that I -- an interested and motivated lay reader -- am part of the target audience of E&M. As such, though I credit Wallace for his efforts, I cannot applaud his results.
