How is mathematics related to frequency related to pitch? We found out from our favourite music correspondent, Oli Freke! In this podcast you can hear how the music we love emerges from pure mathematical beats. This podcast was originally released earlier this year when musician Ed Sheeran was in the news as he was being sued for similarities between his song Thinking out loud from 2014, and Marvin Gaye's song Get it on from 1973. But, given the way we write music to fit into specific genres, is...

We humans have many rules and regulations surrounding noise — because we recognise that noise disruption is annoying, stressful, and ultimately robs us of our health. Spare a thought for whales then, who have to put up with the constant noise caused by shipping and the construction of oil rigs and wind farms in the oceans. There are concerns that the noise pollution we cause bothers and confused the whales so much, it may even disrupt their ability to go on their annual migrations. In this episo...

Did you do anything fun on your summer holidays? The mathematicians in this podcast spent some of their summer helping to create the perfect smoothie, getting the most sugar out of sugar cane, and attacking other important real-world problems. They did all this attending the Graduate Modelling Camp , which is organised every year by the Newton Gateway to Mathematics in Cambridge. The camp gives early career mathematicians a chance to experience life as a mathematical modeller by challenging them...

"I think I'll stop here." This is how, on 23rd June 1993, Andrew Wiles ended his series of lectures at the Isaac Newton Institute (INI), our neighbour here at the Centre for Mathematical Sciences. The applause, so witnesses report, was thunderous. Wiles had just announced a proof that had eluded mathematicians for over 350 years: the proof of Fermat's Last Theorem . Wiles' announcement, 30 years ago today, was a thrilling moment in mathematical history. But Fermat's Last Theorem is not just the ...

You might have heard in the news recently that musician Ed Sheeran was being sued for similarities between his song Thinking out loud from 2014, and Marvin Gaye's song Get it on from 1973. But, given the way we write music to fit into specific genres, is it possible to write unique music with the limited quantity of notes and chords available? In this podcast Oli Freke, our favourite music correspondent, answers this question and plays us real examples of the connections between maths and music....

Did you know that we don't know what 85% of the stuff in our Universe is made of? This mysterious 85% is known as dark matter . We can't see it because it doesn't emit or reflect light, but we know it's there because it exerts a gravitational pull on stars and galaxies, and also bends the path of light. In this podcast we talk to Blake Sherwin about a brand new map of dark matter that has been produced by a consortium of scientists using data from the Atacama Cosmology Telescope which sits high ...

In a tank in an underground laboratory in Cambridge a little green alga is executing a powerful breaststroke. It belongs to a group of algae called volvocales and it doesn't have a brain. So how can it coordinate its tiny little "arms" to perform motions worthy of an Olympic swimmer? Algae going through their paces. ( Movies: Kirsty Wan and Raymond E. Goldstein, for more information see this paper ) In 2019 we visited Ray Goldstein , Schlumberger Professor of Complex Physical Systems at Cambridg...

During the pandemic we all learnt to value the work of epidemiologists, whose mathematical models are essential in giving us an idea of where an epidemic might be heading. But just as there's a wide range of infectious diseases apart from COVID, so there's also a wide range of research questions epidemiologists ask. In this podcast we talk to researchers Helena Stage and Laura Guzmán-Rincón about two such questions. One concerns the fact that a warming climate allows disease-carrying mosquitoes ...

The world needs to move to renewable energy sources, such as solar or wind. The problem with those is that they're intermittent. That's because the Sun doesn't always shine and the wind doesn't always blow. What we need, then, are efficient ways of storing energy: efficient batteries. Currently lithium ion batteries are being used but there are issues around their cost, how long they last, and their safety. Donald Sadoway Hope is on the horizon in the form of liquid metal batteries . At a recent...

There are some numbers you can rely on. The speed of light, c , is 299,792,458 ms-1. The gravitational constant, G , is 6.674 x 10-11m3kg-1s-2. These are examples of what are often called the constants of nature – fundamental physical quantities that seem to be the same everywhere, and unchanging over time. Or are they? Today would have been our wonderful boss, John D. Barrow's , 70th birthday. And to celebrate him and his work we look at the answer to this question in today's podcast. John D. B...
