It turns out, I made an error in Cracking Mathematics. Not (in this case) a mathematical or historical error, although there are plenty of those1 but an error of etiquette: my potted biography of John Horton Conway emphasised the Game of Life above the rest of his work; I imagine

There is a danger, when your book comes plastered in praise from people like Art Benjamin and Ron Graham, that reviewers will hold it to a higher standard than a book that doesn't. That would be unfair, and I'll try to avoid that. What it does well This is a

It’s billed as the calculator that won’t think until you do: if you give it something to evaluate, it will refuse to give you an answer until you give it an acceptable approximation. On the surface, that’s a great idea. If I had a coffee for every time I’ve rolled

It’s a best-seller in France, apparently: the wild-haired but immaculately-dressed Fields Medallist’s story of how he and his colleague solved the Landau damping problem. But therein lies my difficulty with it: I don’t know about, or especially care about, the Landau damping problem. It’s a McGuffin: it might as well
