Alien Earths: What Makes Us Special? - Professor...

Gresham College Lectures ·

2026/02/10

Sometime in 2026, we will discover our 10000th exoplanet, a world around a distant star. This population of worlds has proved remarkably diverse, but hasn’t produced any world like our own. We ask whether this is a coincidence, or whether it could be that our own world is special – and how we might investigate other worlds like our own when we do find them. This lecture was recorded by Chris Lintott on 4th February 2026 at Conway Hall, London. Professor Chris Lintott is a Professor of Astroph...

Will You Be AI’s Pet? - Matt Jones

Gresham College Lectures ·

2026/02/06

Watch the Q&A session here: https://youtu.be/fuk6LYeOCDQ I have two pet dogs; they are happy, wagging their tails and reacting well when I come home from work. They are well fed; have good healthcare; get daily exercise; and have times of play; they do no work or chores. But their long-gone ancestors were wolves, howling at the moon, hunting, creating their packs, taking risks. In this lecture, we will consider a similar domestication of humans by AI, pondering benefits as well as being ...

An Ocean of Air - Helen Czerski

Gresham College Lectures ·

2026/02/03

Watch the Q&A session here: https://youtu.be/_HJt1zjecCo The major environmental challenge of our time is framed in terms of what happens in our atmosphere, and specifically what are called “greenhouse gases”. But what is an atmosphere, and how does it behave? Does the atmosphere vary across the world, and what enters and leaves it normally? This lecture will explore how humanity has taken some things from the air and put other things into it, what the effects have been, and what this me...

Mithras: Master of Mystery - Ronald Hutton

Gresham College Lectures ·

2026/01/30

The cult of Mithras was by far the most famous of the mystery religions of the Roman Empire: private societies of worshippers devoted to a particular deity. It was supposed to have come from Persia, but was actually developed by the Romans themselves and was especially popular in the northern parts of the empire, including Britain. This lecture considers its shrines, myths, membership and rituals, to see how far we can penetrate the secrecy in which it was shrouded. This lecture was recorde...

Why Do We Grieve? - Robin May

Gresham College Lectures ·

2026/01/27

Grieving is a uniquely human emotion – or is it? Is the apparent attachment of elephants or orcas to the bodies of dead relatives a sign of grief, or simply an instinctive behaviour without emotional implications? Why do some people seem able to handle grief so much better than others? And how close are we to finding a pharmaceutical ‘cure’ for grief…and if we find it, should we use it? This lecture was recorded by Professor Robin May on the 21st of January 2026 at Barnard’s Inn Hall, London...

Constable's "The Cornfield": A Bicentenary Harvesting...

Gresham College Lectures ·

2026/01/23

Constable’s painting The Cornfield celebrates its bicentenary in 2026. How has it aged? This is a landscape that has acquired iconic status – a marker of national identity -- as a representation of typically English countryside. How has that Englishness been constituted in the painting? And how does The Cornfield (a view of a partly working landscape) speak to current ideas about relationships and tensions between the natural world and the human presence, especially in our age of environmenta...

Music of Light and Colour - Milton Mermikides

Watch the Q&A session here: https://youtu.be/3B58-fA2b-4 "Colour is the keyboard, the eyes are the hammers, the soul is the piano with many strings." — Kandinsky How do we ‘see’ music, or ‘hear’ images? From Newton’s colour scales assigning tones to the rainbow, artists and composers have long explored the deep connections between sound and vision. Kandinsky’s Compositions and Improvisations; Klee’s polyphonic paintings, and Scriabin’s synaesthetic craft all reveal the scintillat...

Economics and Artificial Intelligence - Daniel Susskind

Gresham College Lectures ·

2026/01/16

ChatGPT, the AI chatbot developed by OpenAI, was the fastest growing app in history. But this achievement, as sudden and remarkable as it might seem, was simply the most recent chapter in a fascinating story that has been unfolding for almost seven decades. This lecture explores the full history of the relationship between AI and work, and how economists have tried to make sense of it. It’s a journey that begins with a remarkable gathering of minds in a non-descript mathematics department at ...

Donald Trump and the Death Penalty - Clive Stafford...

Gresham College Lectures ·

2026/01/06

One of the first executive orders issued by President Trump in January was EO 14164 designed to “restore the death penalty”, though actually aimed at far more (including making the prison conditions of those commuted by Biden reflect the “monstrosity” of their crimes). We will explore what this means for the 2,400 people on America’s death row, at the same time as reviewing the rising levels of innocent people being executed – my own ‘Post Mortem Project’ indicating that as many as 13 percent...

From Mars with Love: Postcards from 50 Years of...

Gresham College Lectures ·

2026/01/05

During the fifty years since the launch of the Viking spacecraft to Mars, our view of the red planet has changed from hostile desert to a world which was once covered in water, and which may just possibly sustain life. Lavishly illustrated with the latest images from the fleet of spacecraft that have explored our neighbour, this lecture considers how Mars’ fate, like that of Earth, was set in the Solar System’s first billion years, and the chaotic environment the process of planet formation p...

Life, Death and Judgement in the Art and Times of...

Gresham College Lectures ·

2025/12/30

This lecture looks at the 'surreal' art of the Early Netherlandish painter Jheronimus Bosch within its historical and cultural context. Although Bosch’s terrifying visions of sin, death, and the hereafter may appear surreal today, especially his highly imaginative depictions of devils, they were tied to the religious attitudes and moralising texts of the period, such as the Ars moriendi, the Dance of Death, and Everyman. It is in this context that one should examine Bosch’s Haywain Triptych, ...

Hecate: Mistress of Magic - Ronald Hutton

Gresham College Lectures ·

2025/12/26

Hecate started as the ruling goddess of the Asian region of Caria, and got taken over by the Greeks as the only one able to operate in every realm of the cosmos. This then gave her special responsibility for travellers, doorways and restless ghosts. That slowly darkened her image, so that she became associated with the night, the moon, and magicians. By the Roman period, she was the goddess of sorcery par excellence, invoked for all sorts of enchantments, good or bad. In the late ancient worl...

Gresham College Lectures ·

2025/12/19

How should we get organised for our later years? With just a little preparation while we are fit and healthy, we can express our wishes for more difficult times. There are simple and positive options to be followed. Not just a will and lasting power of attorney, but simple steps to being independent longer, staying at home longer and enjoying life longer. A little thought now, and hopefully with discussion with family members, will provide reassurance and peace of mind for all. This lecture ...

Why Do We Laugh? - Robin May

Gresham College Lectures ·

2025/12/16

Laughter is an incredibly powerful and yet mysterious emotion. We laugh with delight, but also surprise. We laugh at jokes, but also at embarrassment. Why? What subconscious signal is laughter intended to display? Why do we laugh when someone tickles us and what should we make of the fact that rodents do it too? And why is it that people’s sense of humour differs wildly and yet some drugs can send us all into fits of the giggles, even if there is nothing to laugh at? This lecture was record...

Watch the Q&A session here: https://youtu.be/Lv5h-Pp1r6s Looking at the plant world, one discovers beautiful and fascinating structures in the shape and arrangement of leaves, stems and roots. Some are simple and symmetric, other features are arranged in elegant Fibonacci spirals, yet others exhibit fractal-like patterns. How are these structures created with such regularity and reproducibility? Such arrangements often follow simple rules that we can fully understand mathematically. Thi...

Becoming AI – Your Journey to Assimilation? - Matt Jones

Gresham College Lectures ·

2025/12/09

Wittgenstein wrote: “If a lion could talk, we would not understand it”. That is, as lions and humans are not of the same material, they could not say anything meaningful to each other. AI is not like us; the only way we can have a relationship with it is for us to become like it. We will look at how digital services are already making us machine-like; and, we explore how advanced AI-human fusions may undo our essential “humanness”. This lecture was recorded by Matt Jones on the 25rd of Novem...

Limitarianism and Capitalism - Ingrid Robeyns

Gresham College Lectures ·

2025/12/05

Limitarianism holds that it is immoral to have personal wealth above a certain level. Is this idea compatible with capitalism? Defenders of capitalism have argued that it is not, whereas those who want to move beyond capitalism have urged defenders of limitarianism to clear up this issue. This lecture argues that limitarianism is compatible with some forms of capitalism, and that it would help the debate about the most desirable socio-economic system if we provide more clarity on how these co...

The Great God Pan: Lord of the Wild - Ronald Hutton

Gresham College Lectures ·

2025/11/28

Pan started as a shepherds’ god in a wild and backward area of Greece, but became one of the best-known in the Greek and Roman world. This was partly because the leading city of Athens imported him as a saviour, and partly because he came to represent the freedom, peace and simplicity of the countryside to urban people. He was the most earthy of Greek deities, summing up wild nature in its beauty but also its danger. He was a god of both liberation and menace, and this lecture faces up to him...
