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.

Tag these statements A,B,C. Here is a direct solution.

A implies B so it cannot be the only true statement. Therefore, X cannot be red.

B cannot be true because if "Y is not Red" then Z must be red, rendering both B and C true. So B is False and thus Y=Red.

C remains the only option for the true statement.

Z cannot be Blue or Red so it Z=White. This leaves X=Blue.

Check it out: X=Blue, Y=Red, Z=White renders A, B False while C is True.
