Things to Make and Do in the Fourth Dimension

This is the complete guide to exploring the fascinating world of maths you were never told about at school. Stand-up comedian and mathematician Matt Parker uses bizarre Klein Bottles, unimaginably small pizza slices, knots no one can untie and computers built from dominoes to reveal some of the most exotic and fascinating ideas in mathematics. Starting with simple numbers and algebra, this book goes on to deal with inconceivably big numbers in more dimensions than you ever knew existed. And always with something for you to make or do along the way.

Originally a maths teacher from Australia, Matt Parker now lives in Guildford in a house full of almost every retro video-game console ever made. He is fluent in binary and could write your name in a sequence of 0s and 1s in seconds.When he's not working as the Public Engagement in Mathematics Fellow at Queen Mary University of London, he'll be doing stand-up or converting photographs into Excel spreadsheets.
