Gresham College Lectures

In the 3rd century BCE, the Sicilian polymath Archimedes significantly advanced human understanding of mathematics, geometry and astronomy. By applying his discoveries to practical problems and physical phenomena, he became the founder of statics and hydrostatics, demonstrating how levers work and in turn creating unprecedented war machines such as "Archimedes' claw" and "heat-...

Exercise, diet, rest, and sleep are sometimes seen as optional extras that are desirable if you have the time. They are also topics about which many myths and half-truths abound. This talk will provide rigorous evidence on the importance of mental and physical wellness for not only quality of life but also career success and productivity at work. It will also provide practical tips, based on behav...

The laws of physics may be stated in simple and elegant ways that can be made easy to demonstrate and understand on their own. What is immensely hard to predict from first principles are the consequences of the combinations of these laws acting in concert together, and the richness of the exotic phenomena that we can observe to evolve in the night sky. This talk will examine why laws are simple an...

Is gender equality a key factor in tackling climate change? Many think so, and in this lecture Environment Professor Jacqueline McGlade will explain why in relation to UN Sustainable Development Goal 5 is to 'achieve gender equality and empower all women and girls'. When women are empowered and educated the evidence shows that they have more control over their lives and dedicate more res...

During the last thirty years of his life, Isaac Newton lived in London, where as head of the Royal Mint he moved in wealthy aristocratic circles, exerted substantial political influence, and profited financially from imperial trade and exploitation. To illustrate these themes, this lecture examines an oil painting by William Hogarth illustrating a children's performance of John Dryden's...

'St Thomas has adorned…London by his rising and Canterbury by his setting'. This lecture will explore how the influence of Thomas Becket permeated city life in medieval London until Henry VIII ordered the destruction of his shrine and the removal of his name from all liturgical books. It will include consideration of the first stone bridge over the Thames made possible by offerings in th...

Two hundred years ago a group of conspirators assembled in a Cato Street stable in order to plan the massacre of the whole British cabinet at dinner and bring about revolution. Had they succeeded they would have achieved modern Britain's first terrorist atrocity. They were, however, moved by hunger and by democratic and secular principles, so are comparisons with today's terrorists appro...

Scientific knowledge is advancing at dizzying speed and each day brings new breakthroughs in medical understanding. Unprecedented advances are opening possibilities that only a decade ago would have seemed like science fiction. Yet a deep anxiety pervades our society, raising questions about the wisdom and motives of experts and the implications of new technology. This lecture uses examples from c...

Diaghilev seemed to be the nemesis of traditional ballet, but he was ready to draw on the rigorous classical schooling of his dancers whenever it suited him. Once ugliness had been established as a legitimate option, he was happy to bring back beauty on many occasions alongside the new neoclassical music that he had begun to promote. Stravinsky and Balanchine's Apollo was one such ballet, whi...

Is the clitoris simply a female version of the male penis? Many scientists and biologists in the past thought so. It is only in recent decades that the physiology of the clitoris has become understood. What can debates about these two organs tell us about scientific knowledge and gender identities? How have ideas about the "ideal penis" changed since the eighteenth century? What effect h...

Lung cancer is the second most common cancer in both men and women, but kills the most people through a combination of being common and currently having much less effective treatment. Both treatment and prevention are currently improving, slowly. Mesothelioma, a lung-associated cancer caused by exposure to asbestos, is now the commonest occupational cancer. While treatment for these cancers is sti...

In 2013 Sir Michael Barber declared that "An Avalanche is Coming" and that universities would be swept away by new digital technologies. Six years later nothing seems to have happened, yet there has been change. In this lecture we will review what is commonly called e-learning, including MOOCs, SPOOCs, flipping and DIYU, and see if there are any themes which emerge from the buzzword bing...

Mathematics is often thought of as being a dry and logical subject, and its conclusions free from the vagaries of fashion and misconception. However this is far from the truth. Mathematical misunderstandings, or perhaps a misunderstanding of mathematical ideas and conclusions, can permeate the public consciousness, and once there survive for a long time. This lecture looks at the mythology that ha...

This lecture examines the work of Hugo de Vries, a Dutch botanist who was one of the first to claim that science would allow plants and animals to be designed to order. It also looks at the early twentieth-century 'Station for Experimental Evolution' in New York, and at the utopian vision of Charlotte Gilman Perkins' Herland (1915), a novel describing a lost world populated by women...

Bach's Art of Fugue, Mozart's Requiem, Schubert's Symphony No. 8, Alban Berg's opera Lulu, and Elgar's 3rd Symphony are all pieces that are famously incomplete. This lecture examines the fascination surrounding works that are left unfinished at their composers' deaths. It also looks at the urge that certain of us have to complete these uncompleted works, however unwis...

Europe's Wars of Religion were fought against entire populations, and were punctuated by events remembered as atrocities: such as the siege of Leiden in 1573-4 or, most notoriously, the St Bartholomew's Day Massacres in France in 1572. This lecture will ask how these events came to be so notorious, how and why they were remembered on each side, and how they shaped the history of civil co...

The Hubble Space Telescope is rapidly approaching its 30th birthday, and we will explore some of the amazing insights it has provided on the beauty of our universe and our place in it. But as it approaches retirement, its replacement, the James Webb Space Telescope is under construction. The speaker is a space scientist who has worked on the Webb's instruments; she will take the audience on a...

More council houses were built in Britain than any other country in the 20th century. By the 1970s, one in three households were council tenants. Yet after 1980 £100bn worth of council housing was sold off. How did this expansion come about, what changed - and what lasting effects did the rise and fall of council housing have on our politics, society and economy? Is it now time to reconsider our a...

Albert Einstein's mind-boggling ideas revolutionized our view of the universe. From relativity to curved spacetime, from the Big Bang to black holes and gravitational waves, nothing could be further from our everyday experience than such esoteric concepts, right? Wrong! This lecture will offer a surprising exploration of the wide-ranging consequences of Einstein's ideas, and how they sha...

Advances in medicine allow us to sustain life for longer, but at what cost and at whose choice? Why might the court intervene when a devout Jehovah Witness parent refuses a life-saving blood transfer to their child? Where does religious devotion end and unsafe thought begin? What about cultural and spiritual beliefs that clash with UK 'norms'? Has the law has kept up with the changing so...

The shapes of the orbits of many planets and comets orbiting their mother-ship stars are well known to be circles or ellipses (an idea that was explained by Isaac Newton). But we now understand that, depending on the history and the energy of the orbiting system, other geometric shapes are possible and indeed frequently observed. This talk will explore how simple changes to the circumstances can m...

The extraordinary effort to ban drink must be understood as part of an American culture war, one framed between the country and the city, between the native-born (white Protestants) and foreign-born (Catholics and Jews), between religion and science, between homogeneity and cosmopolitanism, and, of course, between 'drys' and 'wets'. The lecture will show how Prohibition animate...

Stories about islands punctuate the careers of Michael Powell and Emeric Pressburger, from Powell's breakthrough with Edge of the World (1936) to the Hebridean journey of I Know Where I'm Going! (1945), and the final act of their Tales of Hoffmann (1951). What can we learn about the imagination of these very different figures by tracing this motif ? This lecture draws on archival sources...

This lecture-recital will explore the life of Clara Schumann (1819-1896) through her music and surroundings, her achievements and influencers. Deservedly revered by all who knew her, she was a pioneer of female composition, who overcame societal norms to rise to fame as one of the most sought after and celebrated pianists and composers of her generation. A lecture by Fionnuala Moynihan 23 January...

Surveys about people's fears commonly feature public speaking at the very top of the list. Many people believe that public speaking is either something you are born with or without. This talk will provide practical tips that everyone can employ, regardless of their experience, to improve their public speaking. It will highlight what is unique about public speaking compared to other forms of c...
