How do we approach this problem from a mathematical standpoint? The first hypothesis is that bigger is better, in some sense. In this introductory lecture, scaling laws and simple ideas from statistics will be used to study this problem, both in humans and animals, as well as uncover some basic principles that govern brain size and test hypotheses connecting intelligence to size in humans and animals..

The mathematics behind the solution has many useful applications.Meanwhile, paradoxes such as: “some men shave themselves; those that do not shave themselves are shaved by the barber: who shaves the barber?” lead us to deep questions about set theory.An excerpt taken from a lecture by Professor Sarah Hart called 'Mathematical Puzzles and Paradoxes'

What music is the fastest? Gresham College 2024-09-13 | Watch the full lecture here: gresham.ac.uk/watch-now/music-grooveMusic is a temporal art, unfolding like a ribbon and transforming our experience of time itself. This lecture demonstrates how music harnesses our unique and intricate listening faculties creating a complex interplay between sounding events and our internal predictions. This forms a predictive tapestry whereby the listener - usually unconsciously - ‘explains’ temporal events in reference to multi-layered streams of expectational waves. How musicians exploit such expressive opportunities is explored in a wide range of musical styles.An excerpt taken from a lecture by Professor Milton Mermikides called 'The Poetry of Prediction: Musical Time, Rhythm and Groove'

Are you masking your Autism? Gresham College 2024-09-09 | Watch the full lecture here: gresham.ac.uk/watch-now/new-autismOur understanding of autism has changed over the last forty years. Historically, autism was diagnosed based on narrow criteria. Today, while still defined by social and communication difficulties, rigid interests and repetitive behaviours, the autism spectrum is far wider, and the historical under-diagnosis of women and girls is being addressed.‘Autisms’ are more often discussed as neurodivergence rather than a single ‘disorder’ to be treated.

No Registration Requiredhttps://app.sli.do/event/4EnaNQbrg6LQS8bC5WS1BPA lecture by Professor Melissa Lane, Gresham Professor of Rhetoric. For many modern thinkers, the lawgiver has been important as a founding figure of civic identity and cultural values. Rousseau analysed the legacies of Solon and Lycurgus, believing in the need for a lawgiver to make a true social contract possible. By contrast, Nietzsche felt it necessary to seek a lawgiver in history who was also a poet and prophet.This lecture uses their perspectives and others to explore how the figure of the lawgiver has encapsulated key debates in modern political philosophy.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

The U.S. Constitution had to be formed through debate before it could be ratified. Mirroring this, a British constitution must emerge through debates held by the next generation.This lecture indicates schools are a good environment to foster this. For students, there are many contentious issues that tap into discussions at the heart of writing a constitution. Students being punished for swearing raises questions of limits to free speech. Students wishing to intervene when an unpopular peer is bullied would be empowered by constitutional duty obliging them to do so.Schools tend to be authoritarian institutions, benevolent or otherwise, and can either provoke students to develop ideas on power structures and recognise the need for their own rights and duties, or condition them to accept the status quo.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Is it moral to steal data?Throughout history, authorities have struggled to manage individuals’ urges to speak out against injustice and malpractice. IT has given us new means to obtain and publish data that others may wish to protect or even conceal. To some, hackers are heroes. To others, they are criminals.This lecture asks, in an era of mass leaks and high-profile whistleblowing, who decides whether data thieves are to be protected or prosecuted?

Pagan witchcraft, especially in its first publicly apparent form of Wicca, is the most familiar and notorious form of modern Paganism. It is a counter-cultural religion of astonishing boldness, based on feminism, love of nature, personal growth and the redemption of the traditional figure of the witch.This lecture looks at its origins and the roots of its success across the Western world, given it flouts so many conventions. It also discusses what modern Pagan witches actually do, and why they do it.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

No Registration Requiredhttps://app.sli.do/event/fXsaahmnPfBCpF4iXEs5zMA lecture by Professor Alain Goriely FRS, Gresham Professor of Geometry. Diseases such as Alzheimer’s or Parkinson’s are devastating neurological conditions that typically occur at old age and lead to systematic dementia and debilitating symptoms. The underlying mechanisms of these diseases are poorly understood. Yet, a striking feature of these conditions is the characteristic pattern of invasion throughout the brain, leading to well-codified disease stages associated with various cognitive deficits and pathologies.This lecture shows how mathematical modelling can be used to predict dementia’s progression by unravelling some of its universal features.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Diet and agriculture are borderline untouchable “third rail” issues in the climate debate. But with the global food system contributing up to an extra degree of warming by 2100, they cannot be ignored. Sensible policies are hindered by carbon footprinting conventions that distort the impact of methane – in both directions.This lecture explains how understanding methane’s true impact shows that a sustainable livestock industry could be compatible with a stable climate, although it would still need radical change.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

No Registration Requiredhttps://app.sli.do/event/8rTvgzBzoa4gR354pwbcdEA lecture by Professor Clive Stafford Smith JD OBE, Gresham Professor of Law. Regarding the US Constitution, there is a major split between the Originalists (typically conservatives) and those who believe in an organic document that grows with the times. There have been enormous changes since 1789 – the internet is just one example – and the document must change one way or the other.This lecture explores some of the unenumerated rights that might be added. These are not without their own subjective cultural elements. For example, Europeans are much more focused on ‘privacy’ than Americans, and it is debatable whether free speech is truly consistent with privacy.Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.
