Laws versus outcomes: The podcast

John D. Barrow talks to us about the laws of nature, how the complexity of the world conceals elegant mathematical symmetries, and how chaos can arise from order.

Big data and shorter queues

Chris Budd tells us how big data can be used to model riots, analyse photos and shorten airport queues.

What is a black hole – mathematically?

Pau Figueras explains how Einstein's theories predicted the existence of black holes, and how to describe them mathematically.

What is a black hole – physically?

We asked cosmologist Pau Figueras everything we’ve ever wanted to know about black holes. In this podcast he explains what black holes are, physically, and how we hope to observe them.

Cosmology, philosophy and the multiverse

Is cosmology a science or a branch of philosophy? Mathematician and astronomer Bernard Carr gives some answers.

Maths takes flight!

We talk to Shajay Bhooshan about his design for the new maths gallery at the Science Museum London.

Why does cosmology need philosophy?

In this podcast George Ellis explains why the study of the cosmos poses some deep philosophical questions.

Meet the next generation

If you're going to excel in maths it helps to start early — and that's what Peter Scholze certainly did.

The importance of a mathematical community

Ingrid Daubechies, President of the International Mathematical Union, about the importance of community in mathematics.

Maths for the future

Martin Grötschel, Secretary of the International Mathematical Union, about maths at school, integrating developing nations, and his dream of putting all maths that's ever been produced online.

The Fields Medals 2014: Interview with Manjul Bhargava

Manjul Bhargava tells us why playing with maths in important in finding your own way of thinking.

John Milnor: A conversation with a mathematical legend

Why doing maths is like being Lewis Carroll's Red Queen and how to keep going beyond the formidable age of 84.

The Fields Medals 2014: Interview with Martin Hairer

How burning paper can win you a prestigious maths prize.

Einstein's evolving Universe

Cormac O' Raifeartaigh recently made a surprising discovery – an unpublished paper by Albert Einstein that sheds light on how Einstein's thinking about the Universe changed as he tackled some of the big questions in cosmology at the time.

When worlds collide

Fields medallist Cédric Villani talks to us about our solar system, chaos, and what it's like being a mathematical superstar.

It's all maths!

In this podcast we talk to Max Tegmark about his hypothesis that the Universe we live in is a mathematical structure.

Mathematical theatre with X&Y

Mathematics and theatre are both imagined things that need to be consistent. So what better way to explore mathematical ideas than through theatre? We talk to Marcus du Sautoy, Victoria Gould and Dermot Keany about their new show, X&Y.

Do infinities exist in nature? The podcast

Is the Universe finite or infinite? Is there infinity inside a black hole? Is space infinitely divisible or is there a shortest length? Can infinity occur at all in the cosmos or is it a mathematical construct? Find out more in our podcast with Anthony Aguirre, John D. Barrow and George Ellis.

The mathematical Universe

Mathematics does incredibly well at describing the world we live in. Could that be because the Universe itself is a mathematical structure? It's a suggestion that has been put forward by the cosmologist Max Tegmark. We talked to him to find out more.

Rolling out the red carpet for the Travelling Salesman

*Travelling Salesman* is an unusual movie: despite almost every character being a mathematician there's not a mad person in sight. Moreover, the plot centres on one of the greatest unsolved problems in mathematics. We were lucky enough to speak to the writer/director Tim Lanzone about creating drama from mathematics.

The European Congress of MathematicsAt the beginning of July *Plus* went to the European Congress of Mathematics in Krakow! Around 1,000 mathematicians came together there for a week-long programme of talks and seminars. To give you an idea of what it was like we chatted to several of them during one of the coffee breaks.

Maths busking

The 6th European Congress of Mathematics, which took place in Krakow at the beginning of July, wasn't just about mathematicians talking to each other. On the streets of Krakow maths buskers were entertaining the public, handcuffing innocent Krakowians, constructing emergency pentagons and reading minds. So what is maths busking all about? We caught up with Sara Santos, the director of the project, and one of her volunteers to find out.
