Humble Pi
What causes a bridge to sway when it absolutely shouldn't? How does a building start shaking because a gym class jumped along to a 1990 pop track? Why do billions of dollars occasionally vanish from financial systems without obvious explanation? Matt Parker's answer, delivered with considerable wit, is that maths went sideways somewhere along the line. Humble Pi is a tour through the places where numbers and the physical world collide badly, and it turns out there are rather a lot of them. Parker walks us through a surprisingly colourful catalogue of errors: glitches affecting elections, lotteries, and street signs; catastrophic miscalculations involving big data and the internet; a Roman empire that got its sums wrong; and an Olympic shooting team whose story deserves its own documentary. Modern life sits on a foundation of mathematics, quietly and reliably, right up until the moment it doesn't. Parker's argument is that maths isn't some abstract, aloof discipline to be feared or ignored. It's a practical tool, and understanding where it fails helps us appreciate both its power and its limits. The book is peppered with puzzles and challenges, jokes about binary code, geometric socks (yes, really), and three deliberate mistakes hidden somewhere in the text. Spotting them is genuinely satisfying. It's a book that treats getting things wrong not as cause for embarrassment, but as one of the most instructive things that can happen. Accessible, frequently funny, and quietly thought-provoking throughout.
