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.

Here's a thought experiment for you. Let's say you are driving on a road that crosses railroad tracks. A train is coming. You're feeling confident that you can beat the train to the crossing. If you speed up enough, you win, but if too little, you lose. Velocity is, of course, distance traveled per unit of time in a particular direction. Is this a good time to assert that time doesn't exist, and therefore, speeding up is meaningless? If time doesn't exist, are you even moving? Is the train even moving, or are you just imagining it? But the cleanup crew will be absolutely sure that both the car and train had velocity. And the timing was terrible.
