Many claims have been made, both positive and negative, for the transformative nature of internet news in the age of social media. An historical perspective is brought to that debate, by looking at the effects that earlier changes to news production have had for politics, society and commerce. It focuses on two major revolutions - the creation of the mass media in the 19th century, and the broadcasting revolution of the 20th century. What can we learn from history about how deeply the internet c...

Huge volcanic eruptions are the only natural hazard apart from the impact of an asteroid that can cause a global catastrophe. In the short history of civilisation, there have been few volcanic events with global effects. Much larger magnitude eruptions happened regularly in the millions of years previous. Such extreme eruptions perturb global climate for years and can have severe environmental consequences. The modern world is vulnerable to large volcanic events, making the study of their return...

With over 80% of organic carbon being present in the form of cellulose, lignin and starch, it is unsurprising many groups have attempted to use these as feedstock chemicals and materials. Extensive hydrogen bonding makes the plasticisation of starch and the dissolution of cellulose difficult. This talk shows that the incorporation of a simple salt can lead to a flexible plastic with mechanical properties similar to oil derived plastics. Most importantly these plastics are recyclable and ultimate...

Climate change is important, controversial, and the subject of huge debate. Much of our understanding of the future climate comes from the use of complex climate models based on mathematical and physical ideas. In this talk, Professor Budd will describe how these models work and the assumptions that go into them. He will discuss how reliable our predictions of climate change are, and show how mathematicians can give us insights into both past and future. A lecture by Chris Budd OBE, Professor of...

Jesus talked more about money than about anything else. Can the teachings of a penniless ancient ascetic be applied to debates about Brexit, protests about global capitalism, and wider investment not only in defence, alcohol or tobacco but also positively in the environment, sustainability and good governance? Professor Burridge considers ethical material across the New Treatment, drawing upon experience as the Deputy Chair of the Church of England's Ethical Investment Advisory Group. A lecture ...

This lecture will re-examine how the First World War ended, anticipating the centenary commemorations in 2018. It will discuss both why Germany requested a ceasefire, and why the Allies and America granted one. It will argue that the German army was near collapse, and that Germany was not defeated by a 'stab in the back' at home. None the less, the Allies had good reasons not to press on to Berlin. A lecture by David Stevenson, Professor of International History at LSE 7 November 2018 The transc...

Leading actor and Shakespeare scholar Michael Pennington discusses the direct effect on the dramatist's writing of the theatres he wrote for, so different from ours. From cinematic intimacy to heroic spaciousness, his plays reflect his actors' technique and the social range of his audience, allowing him the means to look further and deeper into the human condition, its public and inner life, than any dramatist has achieved before or since. A lecture by Michael Pennington, Actor and Founder of th...

Professor Wilks will discuss the notion of an artificial Companion, a long-term software agent that could be present in any device: a screen, handbag or even a furry toy - and which understands the person it 'lives' with and whose memories and knowledge it comes to acquire and manage through conversation. One can think of a core function of Companion as living with an elderly person, lonely and wanting to revisit their memories and memorabilia, but needing assistance with information and agency....

The Protestant Reformation confronted Europeans with a clamour of religious alternatives. Catholics and Protestants taught their people to doubt the other side's religion (while still believing their own) and taught them to be incredulous while maintaining that faith is a virtue. This lecture will trace how, as Europe's religious landscape fractured, some people fell between the cracks. In long religious wars of attrition, it was all too easy to conclude that all religions were equally true, or ...

Medicine demands factual knowledge, physical skill and the ability to work with patients and colleagues. Most of the time clinicians learn from other clinicians, studying hard within a frame that discourages exploration outside medicine. Focusing on the performance of medicine challenges this frame by connecting with actors, musicians, craftsmen, dancers and other experts. This lecture explores the idea of frames, using illustrations to ask what benefits may result from thinking widely and chall...

Crime thrives in a social environment which is conductive to its commission, and it harms the society which spawns it most of all. That is as true of bribery and corruption as it is true of knife-armed postcode gangs. If the common ethical code that prevents the vast majority from offending in a particular way begins to break down, there is a serious problem. A lecture by Nicholas Cooke QC 30 October 2018 The transcript and downloadable versions of the lecture are available from the Gresham Coll...

THE 2018 PETER NAILOR MEMORIAL LECTURE ON DEFENCE Today's cry in democratic states, and not just from representatives of populist parties, is government with the people rather than government for the people. This presents a problem for issues of war and strategy. Presidents and Prime Ministers, in presenting their decisions to their electorates, use rhetoric borrowed from the Second World War, although they are not committing their states to wars on that scale. The declared ends do not match the...

In his new book, Haunted by Christ, Richard Harries explores the role of faith in the lives of twenty novelists and poets. Non-believers like Samuel Beckett and Philip Pullman as well as believers like T.S. Eliot and W.H. Auden all struggled with faith. At a time when religions language is meaningless or feels stale for many, we can rediscover its freshness and force in the works of novelists and poets. Lord Harries will be in conversation with Alec Ryrie, the new Gresham Professor of Divinity. ...

The dark side of the universe is pervasive. Most of the matter in the universe is dark, most of the energy in the universe is dark. Many searches are underway, on mountain peaks, in deep underground mines, and in space, to discover more about dark matters. Many new telescopes are being constructed on high mountain tops and in space to search for tracers of dark energy.

Physicist John Wheeler asked the famous 'It from bit?' question: what if at its heart the universe is not a collection of particles, forces and fields but rather a collection of bits? If this is true, it leads us to new insights in compression, machine learning, artificial intelligence and maybe even the universe and life itself.

Torture was officially outlawed in France in the 1780s and in Europe during the nineteenth century. In the late twentieth and early twenty-first centuries, it has returned as an instrument of state policy. The defence of torture is no longer viewed with abhorrence. How have languages of patriotism, law and order, justice, the 'civilizing mission', and human rights been used to foster attitudes towards and practices of torture in Western societies? What should our responses be? A lecture by Profe...

THE 2018 ROYAL HISTORICAL SOCIETY COLIN MATTHEW MEMORIAL LECTURE We often think of the British countryside as 'natural' but it is anything but. Not only its fields and hedges, but also its woods, heaths, moors, and fens are largely the product of human activities - of complex systems of management, changing over the centuries. Historians thus have a vital role in nature conservation. We need to understand the specific processes that created habitats in order to ensure their survival into the fut...

'The sense of a new style and a new spirit in poetry came over me', wrote William Hazlitt, recalling the day in 1798 when he heard William Wordsworth reading aloud from Lyrical Ballads, 'It partakes of, and is carried along with, the revolutionary movement of our age'. Jonathan Bate will explain what Hazlitt meant and why Lyrical Ballads, the product of Wordsworth's intimate friendship with Samuel Taylor Coleridge, is one of the greatest and most influential volumes of poetry ever written. A lec...

Some infections come in repeated epidemic waves, others are new to human populations. A known human threat such as influenza may mutate or a new infection jumps the species barrier from animals to humans: recent examples include HIV and Ebola, and the historical example of plague. What happens depends on the route of transmission. Methods for tackling an airborne disease like influenza are different from those for touch (Ebola), insect vector (Zika), water (cholera) or sexual transmission (HIV)....

Was Brexit (the 2016 referendum) argued on the basis of accurate information fairly presented? Slogans were, and may always be, better at gathering votes. With the reality of Brexit a few months away, a sober look at what we actually gain or lose is needed in two areas: What is sovereignty of an island like our own? Could we draw a line round the coast line (and the Irish border) and contain and control all that is inside? And what of rights within that line? Can they all be home grown and natio...

Since Newton, we are used to science making confident predictions about the future. For example, the motion of the planets and the times of the tides. However, some things seem very hard to predict, such as the stock market, or the weather in six months' time. Is this a fault in the way we model these systems, or is there a genuine limit to how far we can predict the future? One explanation comes from the theory of chaos, which illustrates why small changes now can lead to large uncertainty in t...

What does it mean to listen to music? How might the concepts and practices of 'listening' and 'music-making' have first emerged in the story of human development? We journey back in time, to the origins of human society - in the company of research like Steven Mithin's book The Singing Neanderthals - and to the origins of our hearing, to the mechanisms of how our bodies and auditory systems are designed to receive and interpret sound waves. Our music and our listening have been in a symbiotic ro...

If you are a barrister you will be asked 'how can you act for someone who is guilty?'. This is just one of the ethical questions the Bar has to confront. Barristers have a Code of Ethics that governs the working relationship with the client, the court and colleagues but ethical dilemmas in practice are rarely straightforward. Do we make value judgements about our client's culpability? Does that affect how hard we fight their case? Why the answer to those questions should emphatically be 'no'. A ...

Do businesses exist to make profits, or to serve a purpose? This talk will present rigorous evidence showing there need be no trade-off between purpose and profit, contrary to conventional wisdom. It will then turn to the practical 'so what?'. How can we embed purpose in the heart of business so that it extends far beyond a mission statement. The talk will highlight how change cannot be piecemeal but involves holistic reform across many dimensions of a company. A lecture by Professor Alex Edmans...

There was no intellectually sophisticated or articulate 'atheism' in the Middle Ages, but there was plenty of raw scepticism and incredulity. Church courts regularly heard blasphemy cases which went as far as outright denial of God. This lecture will take a tour of medieval unbelief, showing how and why some medieval people defied the powerful orthodoxies of their day: fired not by intellectual or philosophical doubts but by suspicion that 'God' was being used to swindle and manipulate them. A l...
