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.

''Note that another of our rules was broken during this ringing, since each change was repeated one hundred times.''

This doesn't actually break any of the rules of change ringing. When ringing on 6 bells or fewer, changes obviously have to be repeated to get to 5040 changes, so the rule is that no change must be repeated more than any other. The maximum number of times any one change can be repeated is the length of the peal divided by the number of changes in the extent on the number of bells you are ringing. So on 5 bells, you are allowed to ring a 5040 change peal by ringing every change exactly 42 times each, but if some changes were rung 43 times and others on 41, the peal would be disallowed.
