Gresham College Lectures

People often think that surgery is about the skill of a single surgeon. In fact operations depend on teamwork, with nurses, surgeons, anaesthetists and technicians all playing vital roles as they work together. Experts outside medicine need similar skills and have much to teach clinicians. This lecture introduces Rachel Warr, a leading puppeteer and dramaturg. After Rachel demonstrates how she and her colleagues bring puppets to life, we will discuss how her expertise in dexterity, team-working and preparation for performance can shed light on the world of surgery.A lecture by Roger Kneebone, Visiting Professor of Medical Education 27 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/lone-heroic-surgeonGresham College has been giving free public lectures since 1597.

Parasites can dramatically change the behaviour of their hosts. A parasitic worm turns a tropical ant berry-red and causes it to climb high, attractive prey for birds, the worm's next host. A mouse infected by toxoplasma gondii no longer fears cats - making it easier for the parasite to be eaten by its next host, a cat. A jewel wasp precisely injects neurotoxins into its cockroach prey's brain. These parasite manipulations can tell us how brains, including our own, work normally.A lecture by Dr Tristram Wyatt, Research Fellow at the Department of Zoology, University of Oxford 26 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/parasites-controlling-behaviour-brainGresham College has been giving free public lectures since 1597.

Britain's pioneer filmmaker, born 150 years ago in North London, vividly portrayed the variety of life in 'the imperial metropolis' at the end of the 19th century, conscious of its historic appeal but also emphasising the modernity of which he was a part.A lecture by Ian Christie, Visiting Professor in the History of Film and Media 25 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/robert-paul-native-londonGresham College has been giving free public lectures since 1597.

There are an estimated 800 million people living close enough to active volcanoes to be affected when they erupt. As well as casualties from volcanic eruptions there can be major economic losses and societal disruption, especially when communities have to be evacuated. The eruption of Eyjafjallajökull volcano in Iceland in April-May 2010 did not kill anyone but disrupted the travel of millions of people and cost the airline industry billions of dollars. This highlighted the increasing vulnerability of modern globalised societies. New approaches to volcanic hazard assessment and risk management are emerging as more information is required to respond to volcanic emergencies - illustrated by approaches to some recent eruptions, such as the Soufriere Hills Volcano, Montserrat.A lecture by Sir Stephen Sparks, Visiting Professor of Geology 20 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/volcanoes-societyGresham College has been giving free public lectures since 1597.

One of the most mysterious experiences that we come across in psychiatry is 'Psychosis', which refers to a loss of contact with reality. It has many causes and manifestations and it poses major challenges to our understanding. Professor Fletcher proposes that it can be understood in terms of the normal functioning of the mind, which seeks to construct a working model of reality even though it has very little direct contact with that reality.A lecture by Paul Fletcher, Bernard Wolfe Professor of Health Neuroscience at University of Cambridge 19 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/inhabiting-different-realityGresham College has been giving free public lectures since 1597.

The lung has a large surface area, is open to the outside world and is the site for some of the most common serious infections, in particular pneumonia. Several bacteria, viruses and some less common lung infections including tuberculosis and fungal disease can damage the lung, and some occupations and pastimes increase this risk. The heart is less susceptible to infection but infections of the heart valves or structures around the heart, and heart muscle inflammation can be severe. Some lung infections are becoming less common due to vaccination, whilst others are likely to increase globally. Infections via the respiratory route are often the most difficult to combat via public health measures.A lecture by Chris Whitty, Gresham Professor of Physic 13 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/infections-lung-heartGresham College has been giving free public lectures since 1597.

Human vision seems so effortless: from a young age we see the world in high- definition colour. We can tell the difference between a cat and a hat, and 'The man who mistook his wife for a hat' is an anomaly. But despite recent progress, machines still confuse wives for hats. In this lecture, we will examine the phenomenon of computer vision, show how to build a computer vision system and discuss the expectations for the future.A lecture by Richard Harvey, IT Livery Company Professor of IT 12 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/computer-visionGresham College has been giving free public lectures since 1597.

The world's population is rapidly expanding and the majority of this population will live in large city conurbations. What will out future cities look like? How will transport system work, how will people move around, and how will we supply them with energy and remove their waste? What sort of houses will people live in in the future and what will our communities look like? The lecture will show how mathematical models can help us understand how cities work and how they might evolve in the future.A lecture by Chris Budd, Gresham Professor of Geometry 12 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/maths-future-citiesGresham College has been giving free public lectures since 1597.

Musicians make sounds - that much, you'd have thought, is obvious! Yet more than the sounds they make, it's the choices that musicians are making about how and when to play that really matter - choices that are made through listening. John Cage is a composer who revolutionised 20th century music through the choices he has made. This lecture will explore Cage's music, focusing on his most famous piece 4'33". This will be then followed by an interview with pianist and composer Rolf Hind.A lecture by Professor Tom Service, Gresham Professor of Music 11 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/communities-listeners-string-quartet-jazz-band-orchestraGresham College has been giving free public lectures since 1597.

Although financial bubbles are in some sense banal and a feature of financial capitalism, the seeds of the next bubble are often sown by regulatory responses to previous ones. This has been the case since the South Sea Bubble and Mississippi Scheme, and has recurred at regular intervals in the intervening 300 years. This lecture explores how regulators try to prevent what will hopefully be the 'last' bubble and suggests that the most effective regulatory frameworks were developed during the normal operation of markets, not in response to crises.A lecture by Professor D'Maris Coffman, Professor of Economics and Finance of the Built Environment, UCL 7 February 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/bubbles-market-failures-regulatory-responsesGresham College has been giving free public lectures since 1597.
