string theory

If, as string theory suggests, the world is made of strings, then what does that mean for a geometry of points? Find out more in this video.

The mother of all theories

The holy grail for 21st century physics is to produce a unified theory of everything — M-theory is a prime candidate. Find out more in this video.

There are many theories in particle physics that cannot be tested in experiments. Does this make it unscientific? This debate, featuring one of our favourite theoretical physicists, David Tong, explores the question.

In a lower dimension

Could the world be simpler than our senses suggest?

"[String theory] has led us in strange directions that we couldn't conceive of; it's revealed depths of mathematical structure that we couldn't have anticipated". Watch a video interview with Professor Michael Green, winner of the 2014 Fundamental Physics Prize.

Physical finance

The fact that a sizeable proportion of the financial workforce is made up of physicists is one of the industry's best-kept secrets. We talk to Laura Tadrowski, who has made the leap from physics to finance.

How many dimensions are there? In the latest online poll of our Science fiction, science fact project you told us that you'd like an answer to this question. So we went to see theoretical physicist David Berman to find out more.

A bizarre set of of 8-dimensional numbers could explain how to handle string-theory's extra dimensions, why elementary particles come in families of three... and maybe even how spacetime emerges in four dimensions.

The ten dimensions of string theory

String theory has one very unique consequence that no other theory of physics before has had: it predicts the number of dimensions of space-time. But where are these other dimensions hiding and will we ever observe them?

The Abel Prize 2020

This year's Abel Prize has been awarded to Hillel Furstenberg and Gregory Margulis.
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.
