This week returns to my own subject of mathematics, and the challenge of understanding the infinitely big and the infinitely small. You might think that the infinite by its very nature is something we cannot know. But that turns out not to be the case. Indeed, we’ve come up with amazing strategies to navigate infinity, and to understand that there are many different sorts of infinity – some bigger than others! We’ve also found intriguing ways to delve into the infinitely small, including the invention of calculus and the discovery of fractals. So I hope you enjoy this week, as we head off to infinity and beyond.
