Life, choice, and other problems 
We explore some problems physics as we know it has trouble dealing with and a new theory that may provide answers.
Understanding information 
Information is supremely powerful, yet it can't be described by traditional physics. Constructor theory provides a potential answer.
The growth rate of COVID-19 
We all now know about R, but sometimes it can be good to consider another number: the growth rate of an epidemic.
The maths behind combining R ratios 
In a previous article we introduced the problems that can arise when combine the reproduction ratios of a disease in different settings, such as hospitals and the community. In this article we dive into the maths that helps you get to the bottom of these problems.
Finding a way out of lockdown 
Mathematical models can help the nation return to (some sort of) normality.
Social distancing: How close is safe? 
How far can virus-carrying droplets fly in different environments — from buses to supermarkets? Maths can provide some answers.
The problem with combining R ratios 
We explore why you need to be extremely careful when combining the reproduction ratios of a disease in different settings, such as hospitals and the community.
How can maths fight a pandemic? 
How do mathematical models of COVID-19 work and should we believe them? We talk to an epidemiologist, who has been working flat out to inform the government, to find out more.
Less is more: The quest for minimal surfaces 
For over 250 years minimal surfaces have been playing hide and seek with mathematicians. But what are they and why are they interesting?
The power of ants 
Find out how these humble animals have inspired computer algorithms to solve complex real-world problems.
Synchronised swimming 
How do green algae manage a perfect breaststroke even though they haven't got a brain? Enter the maths of synchronisation.
