The accumulation of carbon dioxide in the atmosphere determines what global temperature is reached. So, just like a braking distance, future warming is determined by global emissions today, the year we start emission reductions, and the year we achieve net zero. The goal of climate policy is no longer up for debate: we have to reduce global emissions to net zero. We just need to decide when and how fast. A lecture by Myles Allen recorded on 26 September 2023 at Barnard's Inn Hall, London The tra...

Microplastics - tiny plastic particles less than 5mm long - were first identified in the ocean but are now known to be ubiquitous throughout the environment, within soil, air food and water. Recently, microplastics have been detected in human blood, placenta, and other tissues (liver, lung, colon) raising concerns about potential adverse health effects. This lecture reviews the science on microplastics and whether we should be concerned about them, compared with other known environmental hazards...

This lecture looks at a series of divine female figures in the ancient world from the Middle East to Western Europe: Inanna, Ishtar, Astarte, Aphrodite and Venus. What they have in common, is that to varying degrees they all combined the personae of deities of sexual love and of war. It brings out the special characteristics of each, traces the relationships between them, and shows how each in the sequence, influenced the development of the next. A lecture by Professor Ronald Hutton recorded on ...

Portrayals of hackers in the movies lead us to believe that cybercriminals are young white males who wear hoodies. The cybercriminal population is actually much more diverse in terms of gender, ethnicity, age, neurodiversity and other aspects. Motivations range from the ideological, to profit, to mischief and back again. We will meet the cybercriminals in all their variety and discover how a better understanding of their demographics and drivers can help citizens, businesses and governments prot...

How is music able to convey and trigger such range and depth of emotion? Why does it elicit joy, sorrow, consolation and the chills? Employing research and theoretical models from neuroscience, psychology and musicology, we examine the extraordinary ways that primal and conditioned listening combine to such complex emotive effect. Examples from pop, jazz, rock, film, global, traditional and classical forms are presented under the light of nostalgia, visual imagery, emotional contagion, rhythmic ...

The discovery that we live in an ordinary galaxy, one of several hundred billion in the observable Universe, instigated a profound change in thinking about our place in the Universe. This first lecture covers the Great Debate of the early twentieth century as new telescopes and new ways of observing the cosmos put our Milky Way in its place; and looks at how subsequent observations helped us understand how galaxies like our own formed and evolved. A lecture by Professor Chris Lintott recorded on...

Graph theory is the study of connections, as may be seen in the London Underground map with stations linked by rails, or a transportation network with cities linked by roads. Dating back to the 18th century, the subject increasingly took hold in the 20th century, developing rapidly from mainly recreational puzzles to a mainstream area of study with widespread applications and strong links to computer science. This illustrated historical talk will survey this century of development. A lecture by ...

Did paganism survive all through the Middle Ages, as scholars once thought, remaining the religion of the common people, while the elite had embraced Christianity? Or did it die out earlier? This lecture will consider a broad range of evidence, including figures in seasonal folk rites, carvings in churches, the records of trials for witchcraft and a continuing veneration of natural places such as wells. It will also compare ancient paganism and medieval Christianity as successive religious syste...

What are the risks of using technological innovations in business? There are risks associated with the crypto world, including custodial risk and economic exploits. There are also regulatory risks with competition from central banks issuing their own digital currencies, and risks associated with extrapolation from patterns detected in big data by AI systems. Applying algorithms blindly can lead to miscarriages of justice, exploitation, and discrimination. So how should society mitigate these ris...

Sickle Cell Disease can only be understood in the context of racial politics. Predominantly seen in populations of African heritage, the diagnosis and treatment of this disease from the 1920s onwards draws attention to the importance of culture in biogenetic understandings of disease. Medical practices associated with sickle cell disease also shed light on health care disparities and the cultural construction of pain.

The Annual Sir Thomas Gresham Lecture 2023 The period from 1988 to 2003, was one of extraordinary optimism. Every year the number of democracies increased, human rights improved, violent conflict reduced, there were fewer refugees and there was less global poverty. It was an era of triumph for the western liberal Democratic model for the United States and the politics of the centre ground. But the next 11 years was disrupted by series of humiliating shocks to the west – the fiasco of the Iraq wa...

The climate had a bad year in 2009. Talks collapsed. Emails were hacked. And several papers found even 50-80% reductions weren’t enough: we had to get to net zero. Yet six years later, negotiators from 190 countries acknowledged the need for net zero in the Paris Agreement, even resolving to try to limit warming to 1.5 °C, which means net zero global emissions around 2050. Can it be done? It certainly can. Will it be done? That’s up to all of us. A lecture by Myles Allen recorded on 23 May 2023 ...

AI is another major technological innovation. AI needs data, or more precisely, big organized data. Most data processing is about making it useful for automatic systems such as machine learning, deep learning, and other AI systems. But one big problem with AI systems is that they lack context. An AI system is a pattern recognition machine devoid of any understanding of how the world works. This lecture discusses how AI systems are used in business and their limitations.

In the early 20th century, the system of tonal harmony started to break down. The vertical accumulations of notes became too complex for our powers of memory and recognition, and some have suggested that this led to a loss of meaning and even humanity in music. In this lecture we will discuss expressive uses of atonality, and also the return of familiar chords to music, but outside the grammar that used to give them their logic. A lecture by Marina Frolova-Walker recorded on 18 May 2023 at LSO S...

Microbes have existed on Earth for almost 4 billion years; 3x as long as multicellular organisms and 1000x longer than humans. So what does the future hold? Will recent advances in genetic engineering enable us to create bacterial ‘drug-delivery’ machines or self-replicating microbial vaccines? What will the first human-created lifeform mean for our understanding of biology? Will humanity end with a ‘microbial bang’, or might microbes perhaps be the solution we need to spread our wings beyond th...
