Sometimes, this processing is faulty leading to illusions: shapes or sounds that we perceive differently from their physical reality. These illusions have delighted children and scientists alike for centuries. This lecture reveals how simple geometric illusions can be modelled mathematically, based on our understanding on how visual signals are coded and decoded by the brain, leading to a better understanding of how we process information.This lecture was recorded by Alain Goriely on the 17th of June 2025 at Barnard's Inn Hall, London....2025-07-2551 minGresham College LecturesThe Future of Immunity - Robin MayOur understanding of the human immune system today is vastly different from that of 50 years ago. This knowledge has led to immune-based therapies that would have seemed like science fiction to our grandparents: monoclonal antibodies, T-cell therapies, anti-cancer vaccines, precision immune suppression – the list is endless. In this lecture, we look to the future and ask, “What next for immunity?” This lecture was recorded by Robin May on the 11th of 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...2025-07-2251 minGresham College LecturesThe Maths of Music (and the Music of Maths) - Milton Mermikides and Sarah HartThis 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.

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 ev...2025-07-1849 minGresham College LecturesClimbing Mount Groove: Music and Dance in the Brain - Milton Mermikides and Morten KringelbachThis 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.

Mirroring this, a British constitution must emerge through debates held by the next generation. This lecture indicates schools are a good environment to foster this. For students, there are many contentious issues that tap into discussions at the heart of writing a constitution. Students being punished for swearing raises questions of limits to free speech. Students wishing to intervene when an unpopular peer is bullied would be empowered by constitutional duty obliging them to do so. Schools tend to be authoritarian institutions, benevolent or...2025-06-2437 minGresham College LecturesA New Sky - Chris LintottThe JWST is the most expensive and powerful telescope astronomers have ever constructed.

Financial insecurity affects one’s ability to make rational decisions – studies show it even lowers short-term IQ – making it even harder to improve one’s circumstances in the long run. Furthermore, unlike means-tested social assistance schemes like Universal Credit, a basic income does not involve a severe ‘poverty trap’ and thus, contrary to critics, increases the incentive to take low-paying jobs.

Indeed, cognitive processes are carried out through communications between neurons, leading to synchronisation and oscillations at different frequencies that can be recorded. Together, these oscillations also create waves that propagate through different regions. Apart from this electrical activity, the brain is also the siege of slow chemical waves that can cause migraine and mechanical waves arising from trauma. In this lecture, we will study the influence of all these waves on brain function.This lecture was recorded by Alain Goriely on 18th March 2025 at...2025-04-1156 minGresham College LecturesBanned Books and Freedom of Expression - Rachel PotterThe right to free expression is severely threatened in many places in the world, yet it has also never been so passionately defended.

During that century, especially in Britain, attention switched to a horned divinity associated with the countryside and wild nature, usually personified as the Greek Pan. This lecture explores how and why this happened, and the impact on British culture, when the full subversive potential of this deity as a force for personal liberation became realised. It also shows how the image subsequently evolved from a classical...2025-03-1145 minGresham College LecturesGreen Immunity – How Do Plants Fight Infection? - Robin MayWatch the Q&A session here: https://youtu.be/Et8_myknHq8Most of us rarely think about plant immunity. But, like us, plants can distinguish between different pathogens, trigger a ‘bespoke’ immune response and retain a memory of past infections to boost future immunity. However, plant immune systems also exhibit enviable features like the ability to inherit immunological memory from a parent, or to warn distant individuals of an impending pathogen attack. This lecture investigates how they do all of this and more without a single white blood cell.This lecture was recorded by Robin May...2025-03-1145 minGresham College LecturesUnwritten Laws?

These offer a respite from our often-busy routines. Public spaces are more than just the leftover areas between buildings; they depend on how interests are designed and negotiated, and its success is measured by the interactions that take place in it: the passage of the sun, the root of trees, and even the way they are used by children. However, these areas are constantly threatened by the way local and commercial funding invest in it.Using recent projects, primarily in London and North America, this lecture...2025-02-2836 minGresham College LecturesThe UK’s Generational Wealth Gap - Mike BrewerThe UK's income inequality has remained stable since the 1990s, but household wealth has nearly doubled, mainly driven by soaring house prices. This has widened the wealth gap between generations, with younger people less likely to own homes. Furthermore, weak income growth since the mid-2000s has disproportionately affected younger cohorts.

British cities have faced similar challenges in the past, most notoriously with the ‘Great Stink’ in London in 1858 that led to the construction of Bazalgette’s sewer. Consequently, many cities took utilities into public ownership in the late nineteenth century in what is termed ‘gas and water socialism’. Why did this happen, and why were utilities returned to private ownership in the later twentieth century?

Typically, each region performs different cognitive tasks, from image processing to language. This organisation leads us to model the brain as a network, the ‘brain connectome’. This fundamental view of the brain has become a central paradigm for neurosciences linking topological properties of networks to brain functions. This lecture presents ideas from graph theory to study this network and understand the way that the brain learns and operates.This lecture was...2025-02-1156 minGresham College LecturesBreaking the Fourth Wall of Sound: The Paradox of Screen Music - Milton MermikidesSound and music hold a strange and powerful role in film, TV and video games, aiding narrative and emotional impact. They can even exist in the world of ‘the film’ – heard by the characters – or in the world of the audience. Music can even break the fourth wall, travelling through and blurring these conventionally separate worlds. By examining films through history from Blazing Saddles, Elf, The Truman Show to Birdman, we explore this ‘fantastical gap’ and its transformative effect on the audience.This lecture was recorded by Milton Mermikides on 16th January 2025 at Rich Mix, London.Milton M...2025-02-0754 minGresham College Lectures‘Is it in Pevsner?’: A Short History of the ‘Buildings of …' Series - Charles O'BrienWatch the Q&A session here: https://youtu.be/LUyFLOUi-D4This lecture traces the history of this famous series by Sir Nikolaus Pevsner, starting from its conception in 1947.
