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.

Children may understand time better than adults. Raised in a world with DVDs and videos a child is keenly aware of fast forwarding slowing and reversing a video. When time slows motion slows and faster motion is seen with faster time. Time at least superficially seems to be linked to motion. However a simple thought experiment can provide further insight. Imagine a satellite orbiting a larger mass. Imagine time slowing down for this system. We expect to see that the orbital motion will be slower. However for that to happen the force keeping the two objects together in orbit will also have to get weaker. Similiarly if we imagine a faster time we will expect a faster motion and the attractive force between the two masses will have to be stronger. So time involves both motion and forces.
