Gresham College Lectures

Tiling involves filling a plane or space with repeated elements, known as tiles. This simple concept is deeply embedded in the natural world and human design, appearing in structures as varied as the hexagonal wax cells of a beehive and decorative wallpapers. While regular hard tiles—geometric shapes with straight edges that fit together without gaps or overlaps—are common in human-made designs, nature often favours soft or irregular patterns, shaped by physical forces. In this lecture, I will explore how both regular and irregular tiling patterns, hard and soft, emerge in nature and the underlying mathematical principles that govern their formation.

This lecture was recorded by Alain Goriely on the 28th of April 2026

Alain Goriely is a mathematician with broad interests in mathematical methods, mechanics, sciences, and engineering. He is well known for his contributions to dynamical systems, mathematical biology, as well as fundamental and applied mechanics. He is particularly well known for the development of a mathematical theory of biological growth, culminating with his seminal monograph The Mathematics on Mechanics of Biological Growth (2017).
He received his PhD from the University of Brussels in 1994 where he became a lecturer. In 1996, he joined the University of Arizona where he established a research group within the renowned Program of Applied Mathematics. In 2010, he joined the University of Oxford as the inaugural Statutory Professor of Mathematical Modelling and fellow of St. Catherine’s College. He is currently the Director of the Oxford Centre for Industrial and Applied Mathematics.
In addition, Alain has enjoyed scientific outreach based on problems connected to his research, including tendril perversion in plants, twining plants, umbilical cord knotting, whip cracking, the shape of seashells, brain modelling, and he is the author of a Very Short Introduction to Applied Mathematics (2017). His work has been recognized by a Sloan Fellowship, a Royal Society Wolfson Research Award, the Cozzarelli Prize from the National Academy of Sciences and the Engineering Medal from the Society of Engineering Sciences. He was elected as a Fellow of the Royal Society in 2022.

This lecture was recorded by Helen Czerski on the 19th of February 2026 at Barnard's Inn Hall, London

Helen Czerski is a physicist and oceanographer with a passion for science, sport, books, creativity, hot chocolate and investigating the interesting things in life. 

She is a Professor at the Department of Mechanical Engineering at University College London and her research focus is the physics of breaking waves and bubbles at the ocean surface. These bubbles change underwater sound and light, help transfer gases from ocean to atmosphere (helping the ocean breathe) and also eject ocean material into the air. She has spent months working on research ships in the Antarctic, the Pacific, the North Atlantic and the Arctic, and is an experienced field scientist.

New camera technology can help make stunning footage for natural history programmes but the key to success is down to a lot of hard work, planning and a bit of luck. In this lecture we take a ‘behind the scenes’ look at some of the highs and lows of making television natural history documentaries.

This lecture was recorded by George McGavin on the 3rd of October 2017

Professor McGavin is a British entomologist, explorer and author. He is an Honorary Research Associate at Oxford University Museum of Natural History and the Department of Zoology. He is also a Fellow of the Linnean Society and the Royal Geographical Society.

This episode of the Gresham College Podcast features an interview with Robin May, hosted by Jeoffrey Sarpong. Professor Robin May is a Professor of Infectious Disease at the University of Birmingham, and (interim) Chief Scientist at the UK Health Security Agency.

We cover what's actually happening in your brain when you lose someone, why grief is hardwired from childhood, whether animals grieve, and what ancient burial sites tell us about human emotion 78,000 years ago. Then we shift to love — the physical symptoms of infatuation, why your amygdala shuts down around a new partner, why the honeymoon phase lasts 12–18 months, and why heartbreak can literally feel like withdrawal.
Plus: audience questions on anxiety and love, chatbot grief, abusive relationships, and whether oxytocin is really a "love drug."
