This lecture analyses the ‘psychedelic era’ of the Beatles, from Sgt. Peppers Lonely Hearts Club Band to Let it Be, a period of staggering musical invention and experimentalism. We explore the mechanics behind the magic, untangling the layers of harmony, melody, lyrics, structure and technology, and how these all combine in ways both accessible and ground-breaking. This ‘Magical Mystery Tour’ pulls back the curtain on these timeless tracks, illuminating the craft of their transporting effects.

This lecture was recorded by Milton Mermikides on 12th September 2024 at LSO St Luke's, London.

Milton Mermikides  is Gresham Professor of Music.

He is Associate Professor in Music at the University of Surrey, Professor of Guitar at the Royal College of Music and Deputy Director of the International Guitar Research Centre.

Shakespeare lived in a period of exciting mathematical innovations, from arithmetic to astronomy, and from probability to music. Remarkably, many of those innovations are mentioned, or at least hinted at, in his plays. Rob Eastaway will explore the surprising ways in which mathematical ideas connect with Shakespeare and reveals that the playwright could be as creative with numbers as he was with words. Along the way you will discover surprising new mathematical insights on the Elizabethan world.

This lecture was recorded by Rob Eastaway on 9th October 2024 at Barnard's Inn Hall, London.

Rob Eastaway is best known as the author of several bestselling popular maths books, including Why Do Buses Come in Threes? and Maths On the Back of an Envelope. With Mike Askew, he wrote Maths for Mums & Dads, a book that helps parents to understand the new methods being used to teach maths. The American edition was published in 2010 entitled Old Dogs, New Math.

Rob has given hundreds of maths talks across the world to audiences of all ages, including several family lectures at the Royal Institution, and he is Director of Maths Inspiration, a programme of interactive lecture shows for teenagers, held in theatres across the UK. From 2019 to 2023 he was the puzzle adviser for New Scientist magazine.

We communicate when we have information to share. The development of signals from signs visible over short distances to wireless transfer of billions of data-heavy messages worldwide is full of surprising characters, none more so than the Hollywood starlet who made Wi-Fi and GPS possible and received public recognition only in the final few years of her life. This lecture traces the development of technologies for messaging and signals, from wireless to wired and back again.

As the leaders of the oil and gas industry flew into Houston for CERAWeek, 2024, oil was over $80 per barrel and demand higher than ever. There was little discussion of “transitioning away from fossil fuels” as agreed at COP28 in Dubai. In the run-up to COP29, this lecture will set out the critical need to change the narrative, so those with the ability and resources to solve the climate problem have less incentive to shuffle responsibility onto those (like you) who do not.

Space itself is wobbly. We exist on a choppy sea, its surface roiled by disturbances caused by the movements of black holes hundreds of millions of light-years away. The detection of these 'gravitational waves' by observatories such as LIGO is a story of scientific persistence and precision engineering, resulting in a completely new way of looking at the cosmos. The lecture will highlight the latest results from LIGO's observing run, discuss the nature of black holes - the most mysterious of astronomical objects - and explain how the gold in your jewellery was made.

Traditional risk factors for mental illness include genetics, perinatal factors, substance use, negative life events, trauma and organic disorders. Yet, more recently, it has been found that higher rates of mental illness are also seen in minoritised and marginalised groups. This lecture outlines the different types of discrimination – personally mediated, structural/institutional and internalised – and the evidence linking these with an increased risk of mental illness.

This lecture highlights how luck, timing, and spontaneous decisions shaped their fates, urging us to reframe the way we think about, analyse, and write about the past.

With Brexit, the US presidential election and the Covid pandemic, conspiracy theories now seem to be everywhere. It’s commonly argued that the internet has fuelled their popularity, leading to a loss of faith in mainstream media, science, democracy and even truth itself. But what if the rise of conspiracy theories is a symptom rather than the cause of a collapse of trust in civic institutions?

What links an ancient shipwreck to the textile mills of Northern England? Both contained forerunners of the computing we use today. Computer language and software also have a long history, featuring military research and the repurposing of early programs widely used in manufacturing. This lecture will delve far back into the archives of processing, prediction, difference, and analytical engines, to discover who really made them work.

The human brain has a very distinct and complex appearance with valleys and ridges folding over themselves. The same convolutions are found in large mammals, but not in smaller ones. This observation suggests that size and geometry play a role. Yet, these beautiful shapes have defied a complete description or understanding. 

This lecture will address questions stemming from this picture: How do these shapes emerge? How are they arranged? Simple mathematical models can help us understand the emergence of these beautiful patterns during development as well as their pathology.
