If you like your maths in unusual contexts, then this is the issue for you! We explore the power of origami to solve ancient (and very modern) problems, find the maths in fashion, and marvel at the complexities of church bell ringing. But it's not all fun and games, as we investigate the controversies surrounding breast screening and the maths behind drug-induced hallucinations, find out how to predict the impact of natural catastrophes, and answer some deep questions about the Universe.
