As COP28, the 2023 United Nations Climate Change Conference, kicks off we look at how maths can help understand the climate crisis.

How do you create dramatic film out of mathematics? We find out with writer and director Timothy Lanzone.

Mathematics plays a central role in understanding how infectious diseases spread. This collection of articles looks at some basic concepts in epidemiology to help you understand this fascinating and important field, and set you up for further study.

Find out why the formula we use to work out conditional probabilities is true!

- We talk about a play that explores the fascinating mathematical collaboration between the mathematicians GH Hardy and Srinivasa Ramanujan.

Suppose X is player 1 and Y is player 2 and the moves are x1 ... y1, x2 ... y2 etc where each of the xi and yj are pairs of co-ordinates (here represented as a single symbol).

Suppose Y, the second player, has a winning strategy y1 ... yn irrespective of what X does.

Then all that X ever had to do was to have adopted the same sequence as x1 ... xn and X would win before Y.

This argument sketches over a few details, but the key point is that X's initial extra move can never act as a hindrance to X, only as a bonus offering further chances of a square. It increases opportunities for X whilst introducing no extra risks or vulnerabilities.

But must the game end in a win for somebody? Is stalemate possible?
