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.

Hoping my logic holds up:

1) If X is Red true then Y is not red also true: Contradicts initial premise that only one of given statements is true. Hence X is not Red. X is Blue or White.

2) If Y is not Red then it is Blue or White. If Z is not Blue then it is Red or White.

3) If Y not Red is true then Z not Blue is false as only one of these statements can be true. In which case Z is blue and 2) above means Y is white. However this would mean X is red which contradicts 1) above.

4) With Z not blue true, Y not Red is false. Y is red, 2) gives Z white and 1) gives X blue.

Lines up with statements given as follows:

X is Red - False. X is Blue.

Y is not Red - False. Y is Red

Z is not Blue - True. Z is White
