Editorial Reviews
Review
The book gets better with every reading. ... It is great for sharing, and for explaining why we like mathematics so much. Get it with someone small you love, and start a journey. ... This book would clearly make a great present for mathematicians to give to their children. --LMS Newsletter
Schwartz does a very nice job of mixing very elementary ideas with mathematical content that will be new even to mathematicians, making for a fun and enlightening reading experience. ... A written review such as this cannot capture the spirit of Schwartz s book, every page of which is illustrated with bright colors and beautiful drawings that are appealing to look at even beyond the mathematics that they convey. --Mathematical Association of America

About the author

Richard Schwartz grew up in Los Angeles. He wore only blue clothes between the ages of 7 and 11. He spent his youth obsessively playing tennis until video games distracted him. He majored in math at UCLA, got a PhD in math from Princeton, and is currently the Chancellor's Professor of Mathematics at Brown University. His research interests lie in geometry and dynamics. He likes to do mathematical experiments on the computer and then find proofs for the results he discovers.
Rich was an Invited Speaker at the 2002 International Congress of Mathematicians, a Guggenheim Fellow in 2003, a Clay Research Scholar in 2009, and Simons Fellow in 2012. He is the author of a number of books, including Spherical CR Geometry and Dehn Surgery, Outer Billiards on Kites, You Can Count on Monsters, Man Versus Dog, Unnecessary Surgery, and The Extra Toaster. He lives with his wife and two daughters in Barrington, Rhode Island. In his spare time, he listens to music, writes comic books, cycles on the bike path near his house, walks on the beach, or spends time with his family.

I should note that I write this review as someone who has a long admiration for large numbers; I distinctly recall reading a few essays by Isaac Azimov as a kid and taking a journey similar to what this book does.
It's fun and inventive, so the very few flaws stand out a bit. The most notable flaw comes from the author's choice to have the text flow in all sorts of random directions and sometimes to break it up and have phrases connect in non-linear ways. For the most part, this is good and adds a whimsical touch to the layout. However, there are several pages where this tendency disrupts the flow to a point that a reader may have some difficulty figuring out what order the words are even supposed to be read in. If there were a rationale behind this ambiguity (poetic license, interesting wordplay created by the different types of juxtapositions possible in the layout, etc.), that would be okay. But here it just comes across as poor planning that makes the text unnecessarily complex to follow. Again, this happens only on a small number of pages, but it's enough of an issue that a graphical designer or editor might have been able to suggest easy ways to fix it. (The ending note implies the author created all the graphics and layout himself.)
My other minor quibbles have to do with the time spent on certain concepts and types of explanation. Most kids tend to love *names* for large numbers, which they can throw around in silly ways. But the author moves into abstraction a bit too quickly and doesn't allow enough time to digest the names and orders of magnitude for numbers somewhat larger than a billion or so. He even goes so far as to call things like quadrillion, quintillion, etc. just a "list of funny names for some of the powers of 10." No hint at how that naming system works, or any kind of consistent build-up in orders of magnitude there with illustrations/examples (until we get to astronomical masses for septillion through nonillion). I imagine kids would be much happier to walk around using cool words like "quadrillion" and "octillion" or a "googol" or "googolplex," but they abstractions of exponential notation and other symbolic systems don't give rise to such naming of large numbers. It would have been nice to linger a bit more on that stuff, since this book also goes beyond other children's books in even getting to numbers on that scale, rather than stopping at billions or trillions.
The use of combinatorics for examples is also great, but again there could have just been a little more detail there to show how fast combinations and permutations grow. It's fun to tell kids there are quintillions of ways to color a checkerboard, but most kids (and adults, for that matter) won't have an intuitive sense of how fast combinatorial results grow, so some of these examples don't do justice to the hugeness of the numbers (like, say, the number of atoms in the earth or whatever). Again, I don't think the examples are bad -- just that combinatorics and rapid growth needs to be illustrated and explained as well as exponential notation, "plex," etc. are.
My last minor criticism is with the few times "problems" are posed in the text (mostly of the form "Is X bigger than Y?") with no answers or even hints at how to think about them. Why bother stating these problems at all? Many of them would require significantly more advanced mathematical skills and intuition than the book assumes from readers.
No book is ever perfect, but given the brevity of the text, these minor issues can stand out. Personally, I think this book would be better understood as a guide into the way mathematical notation can be used for abstraction and attain a beauty for its own sake, using the case of large number notations as an example. It's NOT really a great book for "understanding" big numbers concretely, as in getting a sense of relative orders of magnitude or whatever. For that, I'd recommend other children's books like "Millions, Billions, and Trillions," "How Much Is a Million?" and similar books.
