Oxford Online Maths Club
Welcome to the club!
The Oxford Online Maths Club is a weekly livestream from the University of Oxford. It’s free, interactive, casual, and relaxed, and the livestreams are recorded so that you can watch back afterwards if you can't make it to the live broadcast on Thursday afternoons. Our regular host is Dr James Munro, and we often have current Oxford students answering questions in chat and appearing on the livestream to talk about maths.
The club is mostly aimed at people about to apply to university or about to start a Maths course, but everyone's welcome and there's no registration needed. Whether you’re the only person you know who’s interested in mathematics, or if you’re an entire sixth-form maths club looking for more maths content, we’re here for you.
Next Livestream
The Oxford Online Maths Club will return in January 2026.

We'd love your suggestions for Maths topics, or feedback or comments on the livestream, which you can also send to the email address above.
Previous Episodes
You can watch previous episodes and access all the further reading with the links below. There's no need to watch the episodes "in order"; choose one with a title that sounds interesting to you!
Season 10 (2025)
2025 Rewind
This is the last episode of OOMC for 2025, and we're taking a lightning-speed look back at the episodes and further reading notes from seasons 9 and 10 of the show!
Magic with Ayliean
Ayliean presents a spell-binding episode with everything you ever wanted to know about magic squares.
Even More Perfect
On this episode, Zoë tells us about multi-perfect numbers; they're even better than perfect numbers!
Random Walks
Imagine a counter that starts at zero and, each second, either goes up by one or down by one. It'll stop at 10 or minus 10 or when you stay stop. Can you play strategically to cut your losses, or to quit while you're ahead?
Network Models
It's another CS takeover on OOMC, with Marcela bringing us maths challenges to do with models of networks.
Quantum Logic
Anjali is back on the Oxford Online Maths Club to tell us about logic gates in both classical mechanics and in quantum mechanics, using complex numbers and matrices.
Morse Code with Ayliean
OOMC is back for Season 10, and we're kicking things off with a guest appearance from none other than Ayliean, with all things Morse! -·-· ··- - ···· · ·-· · (see you there)
Season 9 (2025)
Rabbits & CompSci
In this episode, Ola from the OxWoCS student society tells us about Fibonacci numbers, and we investigate some algorithms to assess their computational complexity!
Primes and Triangles
By special request, we're covering some number theory on the Oxford Online Maths Club, looking for primes and triangles within Pascal's triangle.
Spherical Geometry
Maybe you've studied geometry on the plane or "Euclidean geometry". We live on a (roughly) spherical planet, and so in this episode of the Oxford Online Maths Club, we're looking at geometry on a globe or "spherical geometry".
Pursuit on Graphs
Eve is on the Oxford Online Maths Club with maths involving pursuit (one agent chasing another) on a graph. Depending on the topology, we might be able to avoid capture forever!
Rooting Around
Georgina joins us on the Oxford Online Maths Club to explore what happens to the roots of polynomials as you change the parameters.
Quantum Waves
We've seen waves in music on OOMC, but now in this episode we're going to the quantum realm to find out how studying waves in higher dimensions can help us to understand the shape of the periodic table!
Secret Maths
In this episode, we learn about modular arithmetic with Beth, and apply it to send secret messages.
The Truth Boundary
Where's the boundary between truth and falsehood? What would it mean to be near that boundary? In this episode, we try to explore the space of all maths facts.
Maths of Music and Colour
Maria is back on the show to tell us about the maths for breaking down sound and music and colour into fundamental components.
Automata
In this episode, Sergey demonstrates mathematics at the foundations of computer science, applied to a particular style of computing machine.
Un-shuffling
In this episode, Jack joins the club to show us a maths theorem from a TV show and explore how it works.
Winter Puzzles
We've got some puzzles to solve in this episode, and a problem-solving strategy that might work for other puzzles too! Tamio brings insight from the Oxford Invariants society.
FUNdamental Theorems
Beth is on the show to put the fun into fundamental theorems, with calculus and algebra and more!
Season 8 (2024)
Summer Puzzles
It's the last episode of season 8, and we've got some puzzles for you to think about over the summer.
CompSci Takeover 2!
Alice is back to show us how topology can be applied to problems in Computer Science.
CompSci Takeover!
In our first Computer Science takeover episode, Alice is on the livestream to show us a problem from topology with relevance to data science.
Solid Gold
Divide and Conquer
On this episode, we take a look at an algorithm for the highest common factor, and find out what else we can conquer with it.
Is this your card?
In this episode, we've got a card trick and a mathematical proof that it works, with a connection to graph theory and to matchmaking!
Factorisation
At the start of the previous season, we talked about how 91 is not a prime number. But how can you tell? In this episode, we'll factorise some numbers!
Season 7 (2024)
Two Routes to Hyperbolic Space
In this episode, the last before we take a short break for Easter, James presents two views of hyperbolic space, with an applied maths traffic puzzle and a pure maths heptagon problem.
Predator vs Prey
How can maths help us understand population dynamics? On this episode, we'll find out!
Proof by Story
Once upon a time, there was an episode of the Oxford Online Maths Club where all the proofs took the form of stories. Eve is on the livestream to share some of those stories...
Sounds Like Maths
Music and Maths go together really well; in this episode we're exploring intervals, tuning, and Fourier transforms, with special guest Maria.
Leap Years ft. Matt Parker
For this 29 February episode of the Oxford Online Maths Club, Matt Parker is on the show to talk about the maths of Leap Years!
Colour by Numbers
Sophie is on the livestream in this episode to demonstrate some problems that can be solved by adding a splash of colour!
Six Degrees of Maths Club
Tarek is on the Oxford Online Maths Club in this episode to help us understand how it can be the case that your friends almost always have more friends that you!
Projective Geometry
Do two lines always meet at a point? What would a really big parabola look like? In this episode, Miles shows us what projective geometry is all about.
Maths and the Law
Lawyers have, on occasion, tried to use somewhat dubious mathematical arguments in a court of law. In this episode, author and mathematician Coralie Colmez is on the show to discuss this with us!
Hydra!
It's time to face the hydra; a mythical creature that regrows heads whenever you cut one off. In this episode, we're looking at some variant hydras and some associated number systems.
Waves
Part of the power of mathematics is that one equation can turn up in many different places. In this episode; the wave equation.
Continue this sequence
Take a large power of two and calculate two to the power of that. Is the answer one less than a prime? In this episode; probably not!
Fake primes!
Some numbers aren't prime but feel almost prime. In this episode, we find a way to make that feeling more precise!
