string theory

Mathematics is an indispensable tool in physics, but can physics solve problem in maths? Find out more in this article.

Find out how a theory from physics has provided tools for solving long-standing problems in number theory. And in turn how number theory helps solve the mystery of black holes.

"The 20th century was the interaction of geometry and physics, and the 21st century is the interaction of number theory with physics." Find out why in our conversation with Yang-Hui He from the London Institute of Mathematical Sciences! 

Over the last few decades physicists have been developing a curious idea. Perhaps the world we inhabit is a hologram, lacking a crucial feature of the world as we perceive it: the third dimension.

More than you think! In this episode of our podcast we talk to theoretical physicist David Berman to find out more...

A possible way of resolving the greatest problem of physics.

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 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.

At the heart of modern physics lurks a terrible puzzle: the two main theories that describe the world we live in just won't fit together.

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.

Could the world be simpler than our senses suggest?
