How many people do you need in a room before there'll be a birthday in common? Why is 70 a 'weird' number? How many episodes of South Park has Kenny survived? What is the longest word in the English language (floccinaucinihilipilification, at 29 letters) and what the hell does it mean? Adam Spencer's national Australian breakfast radio show on JJJ is famous for mixing music, laughs and mathematical insights with the weather (if it's sunny and 32, that's 2 to the power of 5). In this, his wacky, zany Book of Numbers, Adam - who was a PhD mathematician before becoming a stand-up comedian and DJ - tells you everything you've ever wanted to know about the numbers 1 to 100, answering all the big questions. You don't need maths training, just a pen and paper, to understand everything in this funny, stimulating book. And hey, you'll even learn how to feed 56 people with 1 pizza.
