Like mathematics? Puzzles? Thinking? Prime numbers? Pi? You need this book.
‘Things to Make and Do in the Fourth Dimension’, written by Matt Parker (if you’re reading this, you probably know him), is the most enjoyable maths book you could hope to find. Learn about hexahexaflexagons (almost as awesome as dodecahedral not-Rubik’s not-cubes), the official way to colour in knots, four-dimensional straws, base-three card tricks, domino calculators, impossible-but-not numbers, binary scarves and Klein bottle beanies
