I'm launching a new monthly maths column, and what better day to do it than Pi Day? Read on to learn what an ancient Egyptian scribe called "Directions for Knowing All Dark Things", why Newton was ashamed by pi, and how our best estimate was wrong for a century

Why the long history of calculating pi will never be completed
Building the full value of pi has been a project thousands of years in the making, but just how much of this infinite number do we actually need, asks our maths columnist Jacob Aron

Book #2 for 2025: "The secret lives of numbers" by Kate Kitagawa and @timothyrevell.bsky.social. A fun tour through the history of math beyond the Greek and Eurocentric stories. Pretty accessible for the non-expert (in my expert opinion). #booksky #mathsky

Ancient Mesopotamians embodied emotions differently to us. They felt happiness in their liver and anger in their thighs and knees! (according to an analysis of cuneiform texts)

Mesopotamians felt happiness in their liver and anger in their thighs
An analysis of ancient cuneiform texts suggests people thought of emotions in a different way almost 3000 years ago, showing how culture influences our most intimate experiences

Behold the spectre!
You might remember a few months back an amazing new shape was discovered called the "hat" that could cover a surface without repeats. Well, it involved an annoying caveat.
Now mathematicians have found shapes that don't need the caveat

Mathematicians make even better never-repeating tile discovery
An unsatisfying caveat in a mathematical breakthrough discovery of a single tile shape that can cover a surface without ever creating a repeating pattern has been eradicated. The newly-discovered "spectre" shape can cover a surface without repeating and without mirror images
