Trefethen's Index Cards: Forty Years of Notes about People, Words and Mathematics
"What's especially original here is the book's structure. It's a collection of thoughts and questions, some playful, some very deep, each compact enough to fit on an index card. Nick has been writing these index cards to himself for the past 40 years. By arranging them longitudinally, he allows us to watch him unfold, captured as if by time-lapse photography, as he matures from promising teenager to the Professor of Numerical Analysis and FRS at Oxford. Whether you're a fellow mathematician, or merely a fellow human being, you're in for a treat you'll never forget. I know of nothing else like it."--Steven Strogatz, Cornell University
