“The Curve of Binding Energy”

John McPhee

Truly astonishing that it took me this long to read this book; it’s thoroughly right up my alley.1 To start with, it’s McPhee, and he’s my favorite nonfiction author. And after that, it’s about nuclear weapons, nuclear power, and proliferation… with a solid digression into nuclear rocketry, which has long been an interest of mine.2 Nothing in the rocketry section was new to me—I’ve read up enough on that to the point that everything was familiar, although the personal story of Taylor, the interviewee, selling Wernher von Braun on the concept wasn’t something I recalled previously.

What was new, and awe-inspiring in a sort of dry-mouthed terror kind of way, was the nuclear weaponry aspect. This is a book about Theodore B. Taylor, one of the world’s greatest experts in the design of atomic weapons. Over the course of the book he does things like, sitting in front of McPhee during an interview, sketch out plans for a low-yield atom bomb that could be built using only commercially-available equipment and products, with the sole exception of the enriched uranium. He does so while carefully using only publicly-available information. And, in the midst of doing it, he describes each likely point in the commercial reactor fuel processing cycle that said fissile materials could be stolen, and exactly what you would need to do to process that form of the material into what you’d need to build a bomb. This book is, in essence, just a little bit short of being an instruction guide on How To Build A Nuke In Your Garage.

Pair that with a series of explorations of nuclear facilities, in-depth review of the various security failings therein, and a memorable anecdote about the time a fourteen-year-old boy came up with credible designs for a hydrogen bomb, and the fact that the we still, nearly 50 years after this book came out, have yet to see a terrorist organization—or just a really motivated whack-job—build their own bomb is, as I said, awe-inspiring in a dry-mouthed terror kind of way. It isn’t nearly as hard as it should be.

That’s really the key point of this whole book, and the thing that kept standing out to me. I had moments of fun dorkiness—laughing aloud about midway through when Taylor, distracted by a thought, started describing his plan to build what we’d today call a hyperloop network. A certain somebody isn’t nearly as inventive as he’d like to pretend he is; this guy was talking about it when you were still in diapers!3

All in all, this book was an absolute delight to read. I’m likely to reread it again in the next month, and only partially because I wound up finishing it with a bit too much lead-time before the actual book club meeting. I just really enjoyed it, and would like to take a second crack at it, this time without the commonplace book beside me to jot down notes. I absolutely recommend the read; check it out.4

It says good things about my devotion to the whole “don’t buy yourself new books until you finish reading all the ones you’ve already bought” plan that I had to sell my book club on reading it so I could sneak it through the “buying books for book club doesn’t count” exception. ↩

I’m a little tempted to publish the essay I wrote in high school about nuclear rocketry, since I dug it up to look at again while reading this, but probably for the best that I don’t. I’m not interested in knowing how bad my writing skills were that long ago. Or, worse, finding out that they’ve decayed. ↩

Admittedly, Not Tony Stark’s approach gets some points for doing tunneling the boring way (ba-dum-tss) instead of through Taylor’s proposed plan of nuclear shaped charges.
That said, Taylor’s expertise, and the paragraph of explaining how well one actually can shape a nuclear explosion when they’re Theodore Taylor, makes it a more credible plan than when I talk about that kind of concept. ↩
