With an academic background in social, cultural anthropology and photography, I have spent the last twenty-five years working on projects that have bridged photographic and archival research. I have witnessed the power of photography as a means to connect communities. I have experienced first-hand the benefits to participants of enabling an emotional connection and inspiring a sense of validation, of feeling seen and valued and heard. That their story matters. That they matter. In this talk, we ...

Earth is a living planet. But how much life is there, and what is it doing? We will discuss the distribution of biomass on Earth, and compare the effects of microbes, wild animals, domesticated animals. The aim of this lecture is to provide concrete examples of how life is woven in with the rest of the planetary engine, expanding the importance of biodiversity from sentiment alone to a matter of survival for both whole ecosystems and our own civilisation. This lecture was recorded by Helen Czers...

Tiling involves filling a plane or space with repeated elements, known as tiles. This simple concept is deeply embedded in the natural world and human design, appearing in structures as varied as the hexagonal wax cells of a beehive and decorative wallpapers. While regular hard tiles—geometric shapes with straight edges that fit together without gaps or overlaps—are common in human-made designs, nature often favours soft or irregular patterns, shaped by physical forces. In this lecture, I will e...

Watch the Q&A session: https://youtu.be/gj4d75_Clgg In this lecture, we look at proposals to limit AI powers and impacts, so bad outcomes are outweighed by social benefits from the technology. I’ll explain design processes (such as Human-Centred AI and Responsible AI) and technological approaches for AI system qualities like trustworthiness, explainability and “human in the loop”. We will explore how we, as individuals, can use AI based systems in discerning ways; and look at what government...

In the future, we may face ‘structural’ technological unemployment in the labour market – where there is no longer enough work to occupy the human workforce. This lecture explains how such a phenomenon is possible at all, particularly given that repeated bouts of automation anxiety in the past have turned out to be wrong. Understanding this challenge is critical given recent claims by the leaders of the large technology companies – that they hope to build an AI that can outperform human beings a...

Hatred is one of the most destructive human emotions, responsible for some of the greatest atrocities that humans have committed against each other. But why did it evolve in the first place? What is the evolutionary advantage of hating someone? Why is hate the ‘evil twin’ of love? And will we ever be able to ‘treat’ hatred and open the door to a utopian world of peaceful coexistence?

In this lecture, we glimpse our best selves and compare that to a world where we lose everything of ourselves to AI. We are glorious creations that revel in agency, freedom and creativity. What do innovations such as cars that don’t need us to drive and creative AIs that remove the effort of, say, writing or music making mean in this context? Further, with a future being forged by limited perspectives, how can human diversity inform better AI for all? This lecture was recorded by Professor Matt ...

It used to be taken for granted that satire uses nasty means to good ends: it ridicules its targets in order to bring about reform. However, in recent years, the role of satire has been challenged and satirists themselves have quite literally come under attack. Some shocking incidents have prompted serious debate about the relations between free speech and hate speech. This lecture will consider the rights and wrongs of satire in a historical context and in the light of our present situation. Th...

Right now, the technological challenge we are most likely to face in the labour market is ‘frictional’ technological unemployment – where there is plenty of work available, but not enough people are able to do it. This lecture explores the phenomenon and its main causes – that people might lack the right skills for the work, not live in the place where the work is created, or have an identity that is at odds with the nature of the work.

What is it that makes an image stick in our memory against our will? People find many of Lee Miller’s combat photographs have this indelible quality, and of these the most powerful are from her witness of the Holocaust. Her stark and harrowing evidence takes us back to one of the most terrible episodes of persecution in the whole grim history of man’s inhumanity to man. In this lecture Miller’s son Antony Penrose talks about why his mother responded to the Holocaust in the way she did, and the w...

Since Pythagoras, we have imagined the universe as a vast, resonant instrument—a cosmic harmony waiting to be heard. From Holst’s orchestral visions of the planets to Tuvan throat singing echoing the murmur of rivers, composers have long sought to capture the music of nature and the heavens. Villa-Lobos shaped melodies from landscapes and architecture, just as scientists now transform earthquake tremors and celestial frequencies into sound. This lecture explores the deep connection between music...

Economic history has been written by men, for men and about men, giving the impression that – until recently – the economy was “just for men”. This lecture rescues from obscurity the many female producers, bankers, and economic revolutionaries who, over the course of human history, have transformed our economic fortunes. It reveals how as women’s economic opportunities have ebbed and flowed, so too have the fortunes of nations, providing a fresh perspective on the “rise and fall” of civilisation...
