Gresham College Lectures

Microbes hold astonishing speed records: the remarkable Thiovulum majus races along at 60 body lengths per second – the equivalent of Usain Bolt completing the 100m sprint in just over 0.8 seconds. Viruses such as SARS-CoV-2 replicate so rapidly that a single infection can produce 100 bn virus particles within a couple of days. And some bacteria lie dormant for millions of years.

This lecture looks at the biology behind these record-breakers, and what they can teach us about creating new materials.

A lecture by Robin May recorded on 8 February 2023 at Barnard's Inn Hall, London.

During debates over the abolition of slavery, supporters of the system claimed that it was vital to the British economy and that abolition would be disastrous. The abolitionists argued that slavery was immoral and that the economy would prosper in its absence. Just how important was slavery to British economic success? This question continues to resonate in modern debates over the historic role of slavery’s profits in the building of country estates or the endowments of charities. 

Please note, this lecture contains descriptions of violence which some viewers may find upsetting.

What are the strengths and weaknesses of the distinction between solicitors and barristers? What is the purpose of the independent Bar in our legal system today? How does England and Wales compare with common law jurisdictions which have abandoned, or have never had, a split profession?

Is the Bar’s history as a bastion of privilege, its various historical monopolies and prerogatives, and its culture and organisation problematic? What are the benefits of an independent Bar?

When the Western Roman Empire crumbled, the Anglo-Saxon peoples who occupied Britain brought their own paganism with them. This was Germanic, with a pantheon of deities that included Woden, Thunor, Tiw and Frig. Its temples were wooden structures that leave scant traces in the landscape, but you can find evidence for their beliefs in cemeteries like Sutton Hoo.

This lecture looks at such evidence and at literature such as Beowulf and the history written by the Christian scholar Bede.

Composers of tonal music, from the 17th century through to the latest jazz tune or film score, think mainly in terms of how their chords succeed each other, rather than taking chords in isolation.

We will investigate the most important succession of chords in Western music, the cadence. Cadences are a kind of punctuation, dividing music into sentences or periods. They are also responsible for creating a sense of relief or suspense.

Why is the deep ocean cold? And why does this matter for global warming?

Doing the maths with pipes and plumbing, not computers, we explore how processes that keep the deep oceans at frigid Arctic temperatures also determine how fast the world is warming in response to rising greenhouse gas concentrations – and also explain why it would be so difficult to say when the warming would stop even if we were to stabilize greenhouse gas concentrations at today’s levels forever.

The field of probability started when a French nobleman asked the mathematician Blaise Pascal to solve a dispute for him about a game consisting of throwing a pair of dice 24 times. Pascal discussed this and other problems with fellow mathematician Pierre de Fermat, in a series of letters in which they arrived at the basic principles of probability theory.

This lecture looks at dice, cards, lotteries, and other games of chance. Can mathematics help us win?

Louis XIV saw himself as a patron of the arts, as well as an absolute monarch and warlord. He talked to his favourite artists and writers, including Bernini, Racine, Andre Lenotre the gardener and Charles Lebrun the painter, almost as equals, and made Versailles an arts and entertainment centre rivalling Rome. Versailles’s influence, like the French language, spread across Europe. In his range and passion, Louis XIV  was unsurpassed as a patron of the arts, both in his time and later.

How is the decentralised finance world organised?

This lecture discusses how cryptographic technology is applied in business. It discusses blockchains and their uses. It explains how smart contracts, open code that automatically executes contracts once certain conditions are fulfilled, are used. It will also look at non-fungible tokens, a type of cryptographic asset on a blockchain with a unique identification code and metadata that distinguishes it from any other.
