    Carbon: Our Flexible Friend that Built the Natural World - Helen Czerski

    Carbon used to be something that was only mentioned in school chemistry classes, but now it seems to be everywhere: on the news, in political debate, in discussions on health, and as a framework for thinking about our civilisation’s future. But the carbon that’s the focus of most of that debate is what’s in the atmosphere, and that’s only about 2% of the accessible carbon on Earth. This lecture puts that 2% in context, showing how the whole carbon cycle works, how we’re affecting it, and looks at the proposed strategies for deliberately manipulating carbon reservoirs in the future. This lecture was recorded by Helen Czerski on the 24th of September 2026 Helen Czerski is a physicist and oceanographer with a passion for science, sport, books, creativity, hot chocolate and investigating the interesting things in life.  She is a Professor at the Department of Mechanical Engineering at University College London and her research focus is the physics of breaking waves and bubbles at the ocean surface. These bubbles change underwater sound and light, help transfer gases from ocean to atmosphere (helping the ocean breathe) and also eject ocean material into the air. She has spent months working on research ships in the Antarctic, the Pacific, the North Atlantic and the Arctic, and is an experienced field scientist.  Helen has been a regular science presenter on the BBC for 15 years, covering the physics of the natural world in BBC2 landmark documentaries (including ‘Orbit’, ‘Operation iceberg’ and ‘Supersenses’), and the physics of everyday life in a range of BBC4 documentaries (including ‘From ice to fire: The incredible science of temperature’, ‘Sound waves: The symphony of physics’, and ‘Colour: The spectrum of science’, along  with many others). She currently co-hosts BBC Radio 4’s flagship climate and environment programme Rare Earth.  Helen's first book Storm in a Teacup won the Italian Asimov Prize and the Louis J. Battan Author prize from the American Meteorological Society. Blue Machine won the Wainwright Prize for Conservation Writing. She was awarded the Institute of Physics Gold Medal in 2018 for her work on physics communication, and an Honorary Fellowship of the British Science Association in 2020. She was a Trustee of Royal Museums Greenwich from 2018-2026, and was one of the 2020 Royal Institution Christmas Lecturers, giving her Lecture on the topic of the ocean.

    Cosmology’s Mad Idea: Inflation & the Creation of Our Universe - Chris Lintott

    Our expanding Universe only makes sense if, early on, it expanded rapidly in a period of cosmic inflation. In this lecture, we consider the evidence for this apparently arbitrary idea, and asks whether we are on the brink of finding inflation’s signature in our observation. As the story moves from theorist's blackboards to desert observatories, and from the cosmos’s first moments to the far future, we question the nature of the Universe, its eventual fate and even the form of scientific enquiry itself. This lecture was recorded by Chris Lintott on the 23rd of September 2026 Professor Chris Lintott is a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College. Having been educated at Magdalene College, Cambridge and University College London, his research now ranges from understanding how galaxies form and evolve, to using machine learning to find the most unusual things in the Universe, to predicting the properties of visiting interstellar asteroids. He was the founder of the Zooniverse citizen science platform, which provides opportunities for more than two million online volunteers to contribute to scientific research, and which was the topic of his first book, 'The Crowd and the Cosmos’. His latest book is ‘Our Accidental Universe’. Professor Lintott is best known for presenting the BBC's long-running Sky at Night program, and as an accomplished lecturer. Away from work, he cooks, suffers through being a fan of Torquay United and Somerset cricket, and spends time with a rescued lurcher, Mr Max. He can often be found at the helm of Oxford’s science comedy night, ‘Huh, That’s Funny’.

    The Myth and Promise of the U.K. Jury Trial - Clive Stafford Smith

    The Lammy plan to eliminate half of U.K. criminal jury trials has provoked a rebellion among many lawmakers. Recent Palestine Action cases highlight the jury’s moral role, with several “perverse verdicts” acquitting activists despite clear evidence. Yet those charged with the lesser offence of “supporting” PA have been denied a jury trial and the chance of acquittal. Compared with U.S. constitutional protections, including impartial juries, vicinage rules, challenges to biased pools, and post‑trial juror inquiry—the U.K. system appears increasingly problematic. In this lecture, Professor Clive Stafford Smith makes the case for stronger jury protections. This lecture was recorded by Clive Stafford Smith on the 17th of September 2026 Clive Stafford Smith JD OBE is a dual UK-US national, the founder and director of  the Justice League a non-profit human rights training centre focused on fostering the next generation of advocates.  He was the Senior Prefect at Radley College, where he studied maths and science; then a Morehead Scholar at the University of North Carolina (Chapel Hill), where he took a degree in Politics; and a Stone Merit Scholar each of his three years at Columbia Law School, graduating in 1984.  He previously founded and directed the legal action charities Louisiana Capital Assistance Center (1993 in New Orleans) and Reprieve (1999 in London). Since 1984 he has tried many capital cases, and helped to represent over 400 people facing execution in the US and elsewhere. He also brought the first challenge to Guantánamo Bay, where he has secured the release of 87 detainees, and continues to assist the remaining 15.  In all five of the cases he has helped bring to the U.S. Supreme Court the petitioner has prevailed.  He has recently taken on the case of Aafia Siddiqui, the woman who has most suffered from the US rendition-to-torture program – abducted with her three children. He continues to work on capital cases in the US, including a Post-Mortem Project where he is investigating the claims of innocence of 184 people executed since 1977. Clive has published a number of books including Bad Men (2008, describing work in Guantánamo) and Injustice (2012, on the capital case of Kris Maharaj), both of which were short-listed for the Orwell Prize; and most recently The Far Side of the Moon (2023), deconstructing the parallel lives of his father and a client Larry Lonchar, both of whom were labelled Bipolar. He has many other publications, including manuals for the defence of capital cases, and law review articles about aspects of capital defence. He has worked on many films and documentaries, starting with Fourteen Days In May (1987), recently ranked as one of the top BBC documentaries of all time.  While continuing his litigation practice, Clive teaches part time at Bristol Law School as well as running a summer programme for 35 students in Dorset, his home. He has received all kinds of awards in recognition of his work, including an OBE by Queen Elizabeth II for “services to humanity” in 2000. He has been a member of the Louisiana State Bar since 1984.  The transcript of the lecture is available from the Gresham College website: https://www.gresham.ac.uk/watch-now/myth-jury Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

    Is the HIV pandemic over? - Matt Higgins

    A stark advert picturing a gravestone chiselled with ‘AIDS: DON’T DIE OF IGNORANCE’ captured the horror of this disease in the 1980s. Now, for HIV-infected people able to access anti-retroviral therapies, life expectancy is normal. How were these amazing medicines developed and how have they transformed lives? Why is it so difficult to eradicate HIV or to develop a vaccine to prevent infection? What does the future hold in the quest to stop the global scourge of AIDS? This lecture was recorded by Matt Higgins  on the 16th of September 2026 Matt studied natural sciences at Christ’s College in the University of Cambridge and a Ph.D. in structural biology at the Laboratory of Molecular Biology. He started his research group with a Royal Society University Research Fellowship in 2005 and moved to the University of Oxford in 2010. He is currently the E. P. Abraham Professor of Structural Biology and a Professorial Fellow at Merton College, Oxford. He is a Fellow of the Academy of Medical Sciences and a member of the European Molecular Biology Organisation.

    Cello - In Search of a Voice - Kate Kennedy

    How do we tell stories of past voices through a cello, the voice of its player? This lecture explores what it means to be separated from your voice, and to find it again. Dr Kate Kennedy traces a journey she took across Europe with her cello, to uncover the stories of instruments and their players. The result was a host of eccentric, sometimes tragic, always extraordinary accounts of silencing and survival, from the Auschwitz orchestra to a shipwreck, and even a cello full of bees. This lecture was recorded by Kate Kennedy on the 9th of September 2026 Dr Kate Kennedy is a biographer, cellist, and broadcaster. She is one of the foremost critics of twentieth-century music, and lectures in Music and English at Oxford University, and is a regular presence on BBC Radio 3.  Kate is the Director of the Oxford Centre for Life-Writing and a Supernumerary Fellow at Wolfson College, Oxford, having previously held Research Fellowships in English and Music at the University of Cambridge. She is also Director of the Centre for the Study of Women Composers, Director of the Museum of Music History, and a Fellow of the Royal Historical Society.  Her most recent book Cello: A Journey Through Silence to Sound was published in August  2024 with Head of Zeus / Bloomsbury. It is a group biography that weaves together four  narratives of cellists who suffered various forms of persecution, injury, and misfortune.  She is also the author of the Dweller in Shadows – A Life of Ivor Gurney (Princeton  University Press), and editor of Literary Britten, Lives of Houses (co-edited with Dame  Hermione Lee), and The Silent Morning – Culture and the Armistice 1918. Both Cello and Dweller in Shadows were shortlisted for the Royal Philharmonic Society prize.  The transcript of the lecture is available from the Gresham College website: https://www.gresham.ac.uk/watch-now/cello-voice Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.
