Gresham College Lectures

This is the fifth and final lecture from the Gresham Festival of Musical Ideas.https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025Professors Lintott and Mermikides present and discuss historical and contemporary musical representations of astronomical data including Pythagoras’s parallelism of tuning purity and celestial movement, Plato’s cosmic harmony in Timaeus, Kepler’s representations of orbital eccentricity as musical scales, Herschel’s blending of music and cosmology, and the tendency of stable planetary systems to ‘find’ harmonic ratios. The contemporary field of astro-sonification – using sound to represent, search and communicate to a diverse audience, astronomical patterns from black hole radiation to exoplanetary systems – is demonstrated with original examples.This lecture was recorded by Milton Mermikides and Chris Lintott on 29th June 2025 at Barnard's Inn Hall, London.Chris is Gresham Professor of Astronomy. He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.

This is the fourth lecture from the Gresham Festival of Musical Ideas.https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025Professors Sarah Hart and Milton Mermikides reveal the deep connections between music and mathematics. Whether that’s the Euclidean rhythms that shape funky grooves, the set theory that maps every possible chord, or a live rendering of the geometric elegance of Gresham Professor Iannis Xenakis’s algorithmic compositions, this event will reveal how maths can help explain – and even inspire – the richness of musical experience.This lecture was recorded by Milton Mermikides and Sarah Hart on 29th June 2025 at Barnard's Inn Hall, London.Sarah Hart was the first woman Professor of Geometry at Gresham College, and Acting Provost between March and October 2025.

This is the first lecture from the Gresham Festival of Musical Ideas.https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025Musical instruments have been found in the archaeological record from at least 40,000 years ago and despite the diversity of human civilization, we are yet to find a culture which lacks music. Other species also make ‘music’ – from a grasshopper’s chirp to a nightingale’s song – but is human music simply an extension of that evolutionary heritage? What can modern studies of genetics and anthropology tell us about the evolution of human musicality? Can neuroscience explain why music evokes such strong emotions? And what happens when the ‘biology of music’ goes wrong?This lecture was recorded by Milton Mermikides and Robin May on 29th June 2025 at Barnard's Inn Hall, London.Robin is Gresham Professor of Physic. He is also Chief Scientific Adviser at the Food Standards Agency (FSA) and Professor of Infectious Disease at the University of Birmingham.

This is the second lecture from the Gresham Festival of Musical Ideas.https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025Why does a rhythm make us tap our feet—or even get up and dance? In conversation with Professor Milton Mermikides, neuroscientist Professor Morten Kringelbach reveals how the brain finds pleasure, meaning, and movement in music. Drawing on extensive brain imaging, analysis and real-world studies, the talk explores how music and dance engage our brain’s predictive systems—where just the right balance of familiarity and surprise creates joy. From funk to fugues, bossa to the Beatles – the talk will offer insights into why groove feels so  good, and how rhythm links brain, body and culture. This lecture was recorded by Milton Mermikides and Morten Kringelbach on 29th June 2025 at Barnard's Inn Hall, London.Professor Kringelbach is the founding director of the "Centre for Eudaimonia and Human Flourishing" at Linacre College, University of Oxford which convenes and fosters an interdisciplinary team of scientists and artists.

This is the third lecture from the Gresham Festival of Musical Ideas.https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025This dialogue presents the what and why of Ancient Greek music, and its profound role in philosophy, society and the individual. Education without music was an impossibility in ancient Greece; virtue without music, equally so. One scholar (writing in the late twentieth century) compared the pervasive social presence and impact of the medium of mousikē in Ancient Greece to that of television. But with its participatory motor training and habituation, mousikē, was also a primary mode of acculturation: a way to shape the perceptual attunement and overall outlook of the members of a political community. Engagement with poetry and music pervaded all aspects of Ancient Greek life, and because musical education was the core of Greek education, it was also the core of Greek citizenship and of the virtues. Different musical modes were even thought to impart distinct virtues; for Plato, training in musicality could harmonise the soul, while changes in musical styles and genres could dislocate the entire polity.This lecture was recorded by Milton Mermikides and Melissa Lane on 29th June 2025 at Barnard's Inn Hall, London.Melissa Lane is Gresham Professor of Rhetoric.

Accra’s James Fort is an iconic monument for Ghana and modern Africa. This lecture explores the fort's evolution -from its role as a trading post in the early European-African encounters, through its significance during the trans-Atlantic trade and enslavement, to its later use as a modern colonial prison in the post-independence era. It also explores its connection to Ghana's liberation movement, particularly its role in imprisoning Dr. Kwame Nkrumah and other political leaders during their resistance to British rule. Today, this monument represents the resilience, talent and creative potential of a sustainable future for Ghana and its youthful population.This lecture was recorded by Elsie Owusu on the 27th of March 2025 at Barnard's Inn Hall, London.Elsie Owusu OBE is a Ghanaian-British architect and urban designer.

We have to stop fossil fuels from causing global warming – before the world stops using fossil fuels. There’s only one solution: safe and permanent disposal of one tonne of carbon dioxide for every tonne still generated by burning fossil fuels. But how do we achieve this without overheating the planet or stoking political conflicts? This lecture presents a simple answer: make carbon dioxide disposal a licensing condition of the sale and use of fossil fuels.This lecture was recorded by Myles Allen on 10th June 2025 at Barnard's Inn Hall, London.Myles is the Frank Jackson Foundation Professor of the Environment.Myles is also  is currently Director of the Oxford Net Zero initiative.

Whether you are human or computer, viruses can ruin your day, so taking steps to avoid them is important. This lecture will ask whether there are similarities between human immunity and computer immunity? Can we use discoveries in one system to help protect against infections in the other? Might we one day take our laptops for regular vaccinations, or run a ‘software update’ on our own immune systems to avoid an emerging pathogen?This lecture was recorded by Robin May & Victoria Baines on 7th May 2025 at Barnard's Inn Hall, London.Robin is Gresham Professor of Physic.He is also Chief Scientific Adviser at the Food Standards Agency (FSA) and Professor of Infectious Disease at the University of Birmingham.Victoria is IT Livery Company Professor of Information Technology.Victoria is a Senior Research Associate of the Intellectual Forum at Jesus College, Cambridge, a Senior Research Fellow of the British Foreign Policy Group, and a Fellow of the British Computer Society.
