coraaThe Pluto Files
, by Neil deGrasse Tyson
I got this book because I saw Tyson on The Daily Show, talking about it, and the whole interview made me grin ear to ear, like a loon. (You can watch it here, if you like.) It's relatively rare that I watch an interview on a show like that and actually want to go get the book, but I did -- immediately. And I'm really glad I did.
The Pluto Files is about 'the rise and fall of America's favorite planet' -- it charts the history of Pluto's discovery, and its special status to Americans. (Pluto was the only planet discovered by an American, and, of course, there's the cartoon dog, named shortly after the planet's discovery.) And then, of course, the complicating factor of the discovery of other Pluto-like icy bodies, which threw into question: was Pluto really a planet at all?
At the heart of the book is a question: what makes a planet a planet? Apparently this question didn't have an actual answer for a surprisingly long time -- effectively, a planet was the set of things we called planets. This was more or less fine when the state of astronomy and astrophysics was such that we weren't aware of the other things out there... but that changed dramatically over the course of the twentieth century, what with the Hubble Space Telescope and the various unmanned probes.
Much of the book is about this debate: what makes a planet a planet? When the other icy bodies orbiting beyond Neptune were discovered (the Kuiper belt objects), the question became: if we find another icy body as big as Pluto -- or bigger -- do we call it a planet, too? What if we find a bunch of them? Will we cheerfully up the number of planets to ten, twelve, fifteen, twenty? (Indeed, at least one Kuiper belt object was found that was bigger than Pluto; if Pluto was a planet, then Eris definitely was a planet, too.) Or does the presence of a wide variety of Kuiper belt objects, much more similar to one another than to the rest of the planets, mean that Pluto isn't really a planet at all? Indeed, the famous 2006 vote to de-planetize Pluto wasn't actually about Pluto at all, something I hadn't been aware of: the vote was to ratify the first formal definition of a planet, and that definition didn't include Pluto.
But the other key topic of the book was the intersection between culture and science. Several people, scientists among them, argued for a cultural definition of 'planet' that could keep Pluto under sort of a historical grandfather clause. In other words, the argument was that Pluto is a planet because 'planet' has more to do with public opinion and historical tradition than scientific definition. And this part of the book included all kinds of fascinating things: songs about Pluto, letters from elementary school students (in the interview, Stewart says, "You got some hate mail about this decision, didn't you?" and Tyson laughs and clarifies: "Hate mail from third graders."), explorations of the effect that nearly eighty years of the Disney dog had on perceptions of Pluto's status, descriptions of the various 'funerals' for Pluto.
One of the things that I really liked about it, too, is that Tyson doesn't pretend neutrality. He's clear from the beginning that his opinion was that Pluto wasn't a planet, and the book is partly an argument for that opinion. I liked that it was straightforward in its biases, and that's part of what made it so entertaining and so... not-textbook-like.
This book was, as far as I'm concerned, a rare find: a pop science book, accessible to practically anyone, but still written by an expert in the field; a book that is informative and funny and opinionated and absolutely delightful. Highly recommended -- and I'm going to track down more of Tyson's books soon.
