What do ancient logic, Stoic philosophy, and paradoxes have in common? Chrysippus of Soli. In this episode, Ben Cornish explores how Chrysippus revolutionised logic and gave Stoicism its rational backbone. Discover his pioneering work in propositional logic, his take on fate and free will, and why his ideas still matter today.

In this episode of The Mathematicians Podcast, host Benjamin Cornish paddles upstream—literally and figuratively—to explore the remarkable life and ideas of Eratosthenes of Cyrene, the polymath who measured the Earth with astonishing precision and devised one of the most famous algorithms in history: the Sieve of Eratosthenes.

In the show today

• How Eratosthenes measured Earth’s circumference over 2,000 years ago

• The ingenious method behind the Sieve of Eratosthenes and why it still matters in modern computing

• His groundbreaking work in geography, including latitude, longitude, and early ideas of a spherical Earth

• His role as chief librarian at the Library of Alexandria—aka the Google of the ancient world

From ancient geometry to prime numbers and historical timekeeping, this episode is a celebration of interdisciplinary thinking, curiosity, and mathematical creativity. Whether you're a teacher, student, or just a curious mind, you'll come away with a renewed appreciation for how math shapes our understanding of the world.

Plus: Learn how to get involved with Un-Natural Numbers, a new YouTube maths chat show supporting emerging voices in math communication.

Grab your ventriloquist dummies and your gimbles, as we catapult ourselves into a story about the worlds first mathematical engineer. If you thought Leonardo Da Vinci was pretty metal, well you're about to meet the 'wood and papyrus' version. It's Philo of Byzantium.

In this week's episode we look at the life an works of the Great Archimedes. A man who was so much more than what we all think, and we all think quite highly of him. But let's look behind the claw, the screw and the lever and find out who was the mathematician behind the engineer.

This week we look at a man who looked at the moon whilst it looked at the sun and thought: "Gosh, that looks far away".

But how far away is the sun, really. Or the better question would be: "How far away are we?"

Let's find out as we measure the life and works of Aristarchus of Samos. The second greatest Samos-ian that we have covered so far.

This episode has been a real favourite of mine to record - I sit down with the co-creator of www.euclidea.xyz to ask all of my puzzling questions on how the game was developed, the inspiration behind the puzzles and the role of Euclidean geometry in today's world.

This week we look up to one of the most influential stargazers of all time. Autolycus, the very first non-Euclidean geometer, even before Euclid hit the scene.
