The author would like to thank Ana, who wanted me to write this book; Silvia, for making it happen and for sharing my loathing of Wuthering Heights, and the other Ana, for neck-breaking design. Thanks, also, to everyone who has entered into the spirit of it and made enthusiastic suggestions, even if I haven’t had room to include them all. Special thanks to Bob for vetting the math and science chapters and pointing out that pi isn’t a recurring decimal. I used to know that.
