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.

I was fortunate to meet John Wheeler when he visited my university to talk about Black Holes in the mid ‘70s just before he went to UT Austin.

I asked him a question that gave him pause… he stumbled backwards.

I asked him if he had questioned his fundamental assumptions, such as is time discrete or is it continuous.

He did not answer at that time, but years later he coined “It from Bit,” which seems based on that question.

My followup question if he answered discrete would have been “Is there a shortest unit of time?” which is implied if time is discrete. If yes, my next question would have been “What exists between those shortest units of time?”

This question has haunted me ever since I met Dr. Wheeler. Have these questions ever been posed and considered?
