Building a theory of quantum gravity

This collection of articles looks at one of the biggest problems in modern physics and at research that aims to solve it.

The travelling salesman

How do you create dramatic film out of mathematics? We find out with writer and director Timothy Lanzone.

e for exponentialAt the beginning of an epidemic the number of infected people grows exponentially. But why does the number e appear in descriptions of this growth?
What is the generation time of a disease?

To work out how a disease will spread you need to know the time between infections.

How can maths fight an epidemic?

How can we use mathematics to model the spread of a disease?

The doubling time of a disease

The doubling time of a disease is the time it takes for the number of cases of the disease to double. How do you calculate it?

The growth rate of a disease

What is the growth rate and what does it tell us about an epidemic?

Disease modelling for beginners

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.

R and herd immunity

What is herd immunity and what does it have to do with a number called R?

Maths in a minute: Algorithms

The word "algorithm" has probably got more usage over the last few years than it has in its entire history. But what exactly is an algorithm?

Maths in a minute: Exponential growth

What do we mean when we say that something grows exponentially?

The universal machineAlan Turing – brilliant mathematician, code breaker during World War II – achieved so much during his tragically short life. But how do you put Turing's life and mathematics on stage... and as a musical?
