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.

To follow up on 1st anon:

The boxes contain 2V and V reward. Half the time you open the 2V and half the time the V box.

If you never switch, on average, you get 3V/2 reward

If you always switch, on average, you get ... 3V/2 reward.

You can't have a strategy in this game, unless you have some idea of what range of values constitutes a large and small reward.

The monty hall problem works because the game master has extra information which he is revealing by opening a door. No such extra information is being revealed here.
