Gresham College Lectures

Since the death of George Floyd in May 2020, some have asked whether we need a police force.This lecture will examine the role and purpose of the police in our society. What do the police do? What is their historical and social context? Does the current system of policing work? If so, for who? Are all citizens in our society policed fairly? Should we defund the police? If there were no police what might replace them? Are the alternatives realistic?A lecture by Leslie Thomas KC recorded on 25 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/policeGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

In partnership with the London Mathematical Society.The first female Fields Medalist Maryam Mirzakhani, left an astonishing mathematical legacy at her untimely death in 2017. This talk will explain the lasting contributions of her work to our understanding of the world, and give a glimpse into Professor Mirzakhani's imaginative and hands-on approach to mathematics. This lecture will be delivered by Professor Holly Krieger who is the Corfield Lecturer in Mathematics and the Corfield Fellow at Murray Edwards College, University of Cambridge.A lecture by Holly Krieger recorded on 24 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/lms-2023Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

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 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/world-zeroGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

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.A lecture by Raghavendra Rau recorded on 22 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/ai-businessGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

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 St Luke's Church, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/atonal-musicGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

** Please note that this lecture will contain several mentions of early animal testing which some audience members may find upsetting**Christopher Wren was part of probably the first ‘research team’ assembled in Oxford in the 17th century, dedicated to better understanding the human body. With colleagues, Wren contributed to: the near-discovery of oxygen; the first human transfusion of blood; the first intravenous therapy and first intravenous anaesthetic; the description of the anatomy of the arteries supplying the brain (the ‘circle of Willis’); and remarkably, the first successful cardiac resuscitation.The lecture will explain the continued relevance of these discoveries.A lecture by Jaideep Pandit recorded on 17 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/wren-medicalGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Florence Nightingale is the founder of modern nursing and a pioneer of data science and medical statistics. Her innovative use of statistical diagrams helped people see just how many deaths were being caused by poor hygiene in military hospitals.This lecture will look at the importance and legacy of Nightingale’s work, which led to her becoming, in 1858, the first woman elected to the Royal Statistical Society.A lecture by Sarah Hart recorded on 16 May 2023 at David Game College, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/maths-nightingaleGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

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 this planet?A lecture by Robin May recorded on 10 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/microbial-futureGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

The normal heart is very robust. Some people are born with abnormalities of the heart structure. Others acquire damage to the heart valves which become too narrow or unable to close properly. The muscle and linings of the heart may be affected by infections, drugs or other inherited or acquired diseases. All of these can cause heart failure or death if not treated.This lecture will consider the prevention and treatment of structural heart disease.A lecture by Sir Chris Whitty recorded on 16 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/heart-diseasesGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Faceless hackers in hoodies, intergalactic warriors, and technology out of human control: are these representations of cyber threats accurate? And what might be their impact on levels of personal safety and security for organisations?This talk presents ideas for how we might empower people to protect themselves and help address human issues in the IT sector by thinking differently about how we portray security threats and operations.A lecture by Victoria Baines recorded on 9 May 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/cybersecurity-humansGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.
