I listened to the audiobook on Audible and the narration was very good. Zero has had a tough time. Though many times mathematicians seemed to veer towards it, they pulled back as it was considered dangerous territory which mortals should not go towards. The clergy wielded control and for a period grew to be very powerful all across Europe. The problem is that zero symbolized nothingness – a void, and was considered the realm of the divine. Nor was it initially considered necessary for everyday life. Infinity (who the author refers to as Zero’s twin) had much the same problem – nothing & everything are matters to stay away from. Numbers can get smaller & smaller or bigger & bigger but not reach zero or infinity. The East, including India had the advantage that these concepts were intrinsically part of philosophy and hence zero was accepted with no resistance. Zero travelled then to Africa and the Middle East where European mathematicians met it and grudgingly accepted that it is critical for completeness & advancement. The golden ratio too went from India to the rest of the world (credited though to Fibonacci for the series he published, rarely acknowledging its antecedents). There continued to be resistance to zero for a time though and there was a period when mathematicians lost support & respect among the clergy in Europe. The initial discussions which cover the history and acceptance of zero are fascinating. The later sections are devoted to outlining the importance of zero in the sciences, especially physics, significantly on cosmology. Without zero, we wouldn’t have got to many concepts such as relativity, black holes, big bang, end state simulations of the universe etc. An interesting book, but should have been more concise, especially in the later sections. My rating: 3.75 / 5.

5out of 5Trevor (I no longer get notified of comments)–I’m not sure if this book quite worked out what it wanted to be. Besides getting to say, ‘and that is the power of zero’, over and over again it wasn’t quite sure where it should pitch itself and the guy writing it was never quite certain how much back knowledge he could rely on his audience actually having. This meant subjects were generally treated too cursory so I was left thinking ‘wait a second, what happened there?’. His discussion of Gauss was very complicated and hard to follow (not near I’m not sure if this book quite worked out what it wanted to be.

This meant subjects were generally treated too cursory so I was left thinking ‘wait a second, what happened there?’. His discussion of Gauss was very complicated and hard to follow (not nearly as interesting as Euclid's Window The Story of Geometry from Parallel Lines to Hyperspace – A book I mentally compared this to throughout) but then, bizarrely, he went into a fairly detailed description of the Doppler effect, for instance. This book would have benefited from being edited by someone who knew virtually nothing about science. And they could have written on the sides of the page either ‘oh, I see’ or ‘WTF?’ There are many interesting little bits to all this that made it worthwhile, though – the stuff on Pythagoras was interesting – I didn’t know he didn’t eat beans because they make people fart and because they look like little genitals (I’ve never really looked closely enough at beans to notice this resemblance, to be honest, but it does sound as good a reason for a food aversion as any other, I guess). I also didn’t know he was killed because he refused to cross a field of beans (makes my rantings about only going into McDonalds to use their toilets – I only make deposits, no withdrawals - sound perfectly enlightened, if you ask me). There were also interesting bits about vanishing points being zeros and therefore the relationship between space and zero being something non-trivial – but all of that stuff is handled much more interestingly in The Pearly Gates of Cyberspace A History of Space from Dante to the Internet (even if I still have problems with the last bits of that book). Look, it wasn’t a bad book – but I felt it struggled due to feeling it had to make zero the core concept of all of science. This is a trend in this sort of book – you know, pick something (nutmeg or coffee or space) and show it as the nexus through which all strands of the universe can be understood. Generally, this is handled better than it has been handled here though. PS - I hadn't realised this is the same guy who wrote Decoding the Universe How the New Science of Information Is Explaining Everything in the Cosmos, from Our Brains to Black Holes - suddenly, things make much more sense.

4out of 5Usha–It's a fascinating and an affirming read. It's difficult to understand any regiment of mathematics and physics without the number zero. Seife reveals, how it's acceptance took time, overcoming of religious and cultural preconceptions and other serious appraisals and tribulations. Without zero, there be no calculus, algebra, astronomy, quantum physics nor understanding of space, beginning and end of the universe, black holes, vacuum and the list goes on into infinity.

They are 1 month, 6 months, etc, then they are 1. Makes sense. I enjoyed how the author used examples that I could relate to when explaining thermodynamics, quantum physics, time-travel, black holes (wormholes), etc. Enjoyed the e (calculus), too. A lot of historical information about our number system is enclosed in this book, e.g., where the word Algebra came from. There are also names, theories, dates and some interesting stories to help bring the time period(s) to life. Appendix E: How to Make Your Own Wormhole (time machine) was humorous. The last chapters dove into physics, time-travel, black holes, our galaxy, how the star distances were measured, how the universe came to be (big bang theory) and how it may end, how we can travel vast distances on little fuel. It was very complicated, but I now understand why we haven't been able to do it yet. The universe is still expanding. Some galaxies are speeding further away from us. There are still large hunks of nothing in space. The author goes into what is going on with our sun. Einstein and his theories are throughout the book, too. Interestingly, all this ties right into zero. A black hole is zero. Vast nothingness. How zero and God correlate. Great book! 5 Star Favorite!

It is a number, and it is an idea; it is a troublemaker, and it is a problem solver.

I enjoyed the actual writing of the book: clear and easy to follow, slightly humorous at times (in a Stephen Hawking kind of way), and clever. I like the chapter titles (beginning with Chapter Zero and ending with Chapter Infinity) and the fact that Seife is not biased. He simply conveys historical and scientific fact, not allowing his opinions to leak through his words. I don't like when scientists make it obvious that they're not only proving theories but also trying to disprove God. Seife never does that--he just presents ideas and explains how zero went from being reviled and feared to respected to something that needs to be erased once more. My only critique is that the first part of the book is very easy to understand, but during the second half when Seife discusses modern mathematics and science, the narrative becomes more difficult to follow if the reader isn't a calculus major or a physicist (neither of which I am...). Still, there are nice illustrations that make Seife's points clearer. I highly recommend this book to anyone interested in the idea of zero, its origins and usefulness, its place in the world, or to anyone who loves math and science.

Here I am, three years later, returning to Zero for a second read. No longer the gullible high school student (now a gullible university student!), I'm apt to be more critical of Zero. Nevertheless, it stands up to a second reading and both inspires and informs. Imagining a world without zero is probably difficult for most people. It was especially difficult for me, as a mathematician who grew up learning calculus and understanding that zero is just another number. Even with Charles Seife leading the way in the first chapter, I still have trouble comprehending this idea that entire civilizations rose and fell—and achieved great things in between—without the concept of a mathematical zero. In that respect, Zero acts as a history of the development of an idea, one that began in Babylonia and spread, via Alexander the Great, to India, where it flourished. Seife's history is necessarily balanced between East and West in this case, as it's impossible to discuss mathematics without discussing India. That being said, I would have liked to learn about how China regarded zero, even if Chinese mathematicians contributed no new developments to the number's importance as their absence from this book seems to imply. This one oversight overlooked, Zero is not your typical history book that starts in ancient Egypt or Greece and insists everything we know flows from there. What's admirable about Zero is Seife's ability to focus on zero. The story intersects with the lives of many famous mathematicians, but the obvious slimness of this book testifies that Seife managed to distill only what was necessary about their lives in his quest to explain the mystery of zero. I'm not trying to imply, "Short books are easier for non-mathematical people to understand," but that's part of the attraction. Although it's heavier on the equations than I remembered, I would still feel comfortable recommending Zero to my non-mathematically-inclined friends. Firstly, Seife's writing is accessible, even when loaded with equations. As long as you have some basic arithmetic left over from high school, you can follow along. And I'd definitely recommend this book to high school students, like I was when I first read it: it's one of those books that opens the mind. Secondly, the narrow focus acts like a window into the history of mathematics. I have A History of Mathematics sitting next to Zero on my desk, and while the former is more complete, I somehow suspect the latter is more appropriate for a general audience. In other words, Zero is a good gateway drug. Where Zero starts to show its seams is in Seife's rhetorical ability, which stretches itself thin even over so thin a volume. He's too dramatic for my taste, especially as he recounted the attitudes and fate of the Pythagoreans. And he's always eager to remind us of how "powerful" zero is. While I agree that zero is a pretty cool number, the constant refrain felt somewhat forced after a while, pulling me out of the book instead of keeping me comfortably ensconced in this little tutorial. Seife devotes only cursory glances at the philosophical arguments offered for or against the acceptance of zero; he tells us about Aristotle's rejection of zero but goes into little detail. While I'm sure he wanted to avoid turning the book into a text on Aristotelian philosophy, I feel like there are gaps here that, if not filled, could have been covered with a more attractive carpet. Not perfect, not as mind-blowing as some mathematical literature I've read, Zero makes it mark because it's adequate at explanation without going overboard. I'm not sure what else to say: if you're interested in the subject, this is a good place to start. And even if you're not, hey, it's only 250 pages. What have you got to lose? Nothing. Zero!

It has lots of pictures and illustrations and appendices, and I am assuming that they mean something. One of them, in theory, even explains how through the power of the dangerous zero, you can make an equation that proves Winston Churchill is a carrot. I would have truly liked to understand that! However, nowhere in this book does Donald Duck leap out of the pages and explain the The Golden Ratio to you a la Mathmagic Land, and that proved to be the downfall of this book and me. Not gonna lie--when I got to the section about calculus, I was overcome by the the old feeling of having a test the next day and not knowing what a differential equation was, and maybe Mr. Taylor would make it a group test and I could force my ex-boyfriend to be my partner and not have to know? God, that's going be a hard email to write. STRESS. STRESS. Where was I? Oh yes. All that said, the early chapters did come with some interesting history sprinkled around all of the equations. I never really noticed the links of old-school Judeo-Christian thought to Aristotle and his rejection of the infinite or the void. I also never realized that the Catholic Church was actually embracing new thinkers until Martin Luther decided to upset the apple cart and they went scrambling back to their traditions and finger-pointing at heretics. These sections were a little textbookish and occasionally hyperbolic ("Zero is dangerous! Zero will ROCK YOUR WORLD. Zero may kill your children!") but I think the info will stick with me. But, in the end, if a=level of book enjoyment, and b=feelings of stupidity, and c=interesting tidbits, then A = c-b will probably give you a negative number . . . which I know we only have thanks to Eastern thought! Also, Winston Churchill is a carrot.

5out of 5Tim–Seife, a science writer, leads us down the rabbit hole we term 'zero'. The mathematical history of the number follows a convoluted path, early on a place-holder in counting systems or a much-feared void forbidden by belief on pain of death. Eventually the path leads to infinity which, like its twin zero, figures the limit of human experience. For Seife this means that nature - described in its native language of mathematics - breaks completely with possible human experience at zero and infinity.

The mathematical history of the number follows a convoluted path, early on a place-holder in counting systems or a much-feared void forbidden by belief on pain of death. Eventually the path leads to infinity which, like its twin zero, figures the limit of human experience. For Seife this means that nature - described in its native language of mathematics - breaks completely with possible human experience at zero and infinity. Yet the need to confront these limits and by increments bring them within the space of the humanly possible is the impulse behind this book. Short as it is, the first two thirds of the work provide an engaging survey of the development and application of 'zero' in mathematics. A substantial part of its current conception is bound up in the development of the calculus which underlies so much of mathematical physics. Relativity theory and the development of thermodynamics spurred further application of the concept in theories of nature. Nonetheless, singularities represent limits to what we know and perhaps can know, as well as what we can do. Zero's enigmatic presence in our thoughts is a gateway to the speculative, sometimes nearly mystical suppositions in a scientific vein that take up the final third of the work. Zero, in Seife's account, is a main character in a story about mathematics and physical science. But his account of the concept as an artifact of culture and of language may offer some additional insight. For example, in common English usage, zero is nothing apart from comparison. The activity of comparing and by extension of measuring is part of this odd number which happens to be even.

I wholeheartedly agree. For one thing, I've found that learning the reasons why people wanted answers to scientific questions has made the science much more interesting. The stories behind the science are also often quite dramatic or even tragic and therefore memorable. These stories give the scientific data a context that makes it easier to remember. And this isn't really too surprising, is it? After all, we've been storytellers for nearly as long as we've been walking upright. We make sense of the world through storytelling, so storytelling seems like an easy way to help make sense of science.

The author takes a seemingly simple topic, then tells us how incredibly complex it really is, and then simplifies it again. Yes, there are pages of equations, some of which I actually understood. But it was a fun read, and he shows how the infinite can be unimaginably large or infinitely small, and how they need each other. The author tells us how this mathematical debate becomes one with the religious debate about the nature of God, and whether He has limits. We see how the ancients Greeks took their debates seriously indeed, and the price of having an unpopular opinion was far worse that getting hateful text messages. Seife tells us about that ancient riddle, about some creature walking one half the distance to a certain point, one jaunt at a time, and in theory can never reach the end, and shows us the single flaw in that argument. Otherwise, we could never get anywhere. As I said, this is a very entertaining book, and the equations shouldn't stop the curious reader.

So here's another shot at it. Zero is essentially an idea. It didn't come from the expert mathematicians in Ancient Egypt, Ancient Greece, or Ancient Rome. Those mathematicians, skilled as they were, had a more practical bent, except for the Greeks, of course. Author Charles Seife explores various mathematical ideas to explain what he means. For example, Seife talks about the Pythagoreans and their "discovery" of irrational numbers. To defend against this idea, they killed the man responsible for leaking the secret. What does this have to do with Zero, though? If you know something of Ancient Greece, you would have heard of Zeno's Paradoxes. They confounded philosophers and mathematicians for centuries because they didn't have the tools necessary to solve them. The Achilles Paradox is probably his most famous. To solve it, all you do is find the limit as a value approaches zero. The Ancient Greeks didn't have a zero, though. They drew diagrams for all their mathematics. How do you draw something with an area of zero? One man was close to figuring it out, Archimedes of Syracuse, but a Roman soldier killed him. The lack of Zero affects our calendar, as well. There is no year zero in the Gregorian Calendar; it jumps from 1 BCE to 1 CE. That fact might not bother you in your everyday life, but it bothers people that have to care about such a fact. Quick, when does the new millennium start? The year 2000 or the year 2001? I was 14 when this argument happened and still remember it faintly. Anyway, according to Seife, Zero and Infinity are intertwined. It lends a mystical quality to the book as a whole. It isn't hard to see this for yourself. All you have to do is find the limit of one divided by a number that approaches zero. The resulting number shoots up to infinity or negative infinity, depending on the side you choose. Although the Babylonians invented Zero as a placeholder, it flourished in India. Alexander the Great took it with him on his journey to conquer Asia. Alexander died, but Zero did not. Indian mathematicians didn't care about irrational numbers or plane figures, but they did play around with numbers. All in all, this book is excellent. It covers a lot of ground in few pages.

In addition to detailing the history of the number’s usage in the mathematics systems of various cultures, the book attempts to tie the concept of zero to more fundamental philosophical struggles that have accompanied the mathematical changes – Aristotelian ethics to Hinduism to the Catholic Church/Copernicus/Galileo debates. The prose does a pretty good job of simplifying major philosophies and major mathematics concepts for the general reader, although about two-thirds of the way through, the history of zero reaches imaginary numbers and proceeds to quantum mechanics, and from then on, the concepts become fairly technical. The biggest problem with the book is that I think Seife doesn’t do an adequate job of convincing me that the number zero is as directly tied to the philosophical struggles of the times as he asserts. He makes the number zero synonymous with “void” and infinity synonymous with “eternity” and therefore mathematical arguments over zero and infinity are the same thing as religious debates over the creation of the universe and eternal destination. It is an extremely large jump that doesn’t come off as convincing. And the last third of the book is more focused on quantum mechanics and cosmology and sort of forgets about the philosophical struggles. An interesting history of the most important number, but not as dangerous an idea as Seife is trying to intimate. Recommended for those who enjoy pop math books.

It's to Seife's credit that he manages to weave out of these eclectic approaches a coherent story that borders at times upon the epic... while never being too important not to include an irreverent tangent about Pythagoras's acute dislike of beans. If anything, Seife trends too sprightly at times. Though I admire his stance in neither dumbing down the material nor making it intimidating for the casual reader, at some point, no matter how breezily one explains black holes or the Casimir effect- there's no disguising that there are some vast concepts being covered. As it is, I believe you definitely have to at least of heard of some of these ideas (particularly in the last third) to enjoy the new contexts he weaves for them in his narrative. Myself, I sort of managed alright with some first year Calculus and Physics schooling. I can't say I ever turned down the chance for more trivia, and Zero delivered in spades. Also, know this: the first appendix details a mathematical proof on why Winston Churchill is a carrot. Rating: 4 stars

4out of 5Jimmy Ele–Amazing book, especially when it gets to the topic of the significance of zero in mathematics and physics. The only improvement that would have made it better is if there were more known about the origin of zero, in particular the ancient Mayan and ancient Indian perspective on the number. Of course, we know that the information on the Mayan perspective was most likely burned by the Spaniards and as for the Indian perspective, perhaps it lies in an ancient scroll somewhere.

5out of 5Sara–The book added a lot to my knowledge and answered the question of the history of zero, but the author exaggerated and magnified the issue far from zero the original subject. Nevertheless it's enjoyable, easy to read, and satisfying.
