[Prof. Daniel Jafferis](https://www.physics.harvard.edu/people/facpages/jafferis) reviews a tensor–matrix model for 2d CFT data constrained by crossing symmetry, and topological expansion conjectured to match pure 3d gravity. He discusses sources of divergences and what remains to establish the duality, then turns to a BCFT extension linked to an open bootstrap. The resulting expansion corresponds to gluing tetrahedra, with the model reproducing certain 3d gravity amplitudes.

Prof. Daniel Jafferis is a physicist at Harvard University. He co-discovered key AdS/CFT dualities and proposed the F-theorem for 3D supersymmetric flows. Prof. Jafferis’s works on tensor–matrix models, holography and the unexpected links between mathematics, geometry and gravity.

Prof. Dmitry Kaledin gives two lectures on the frontiers of modern algebraic geometry. In the first, he explores how classical Hodge theory extends—or fails to extend—to the non-commutative realm. In non-commutative geometry, de Rham cohomology is replaced by periodic cyclic homology, yet many foundational questions remain unresolved and there is no general theory over the complex numbers. Prof. Kaledin outlines a potential new framework for constructing a genuine non-commutative Hodge theory, building on insights from p-adic and crystalline settings and revealing unexpected connections between geometry and arithmetic.

In his second lecture, he presents a general approach to building a homotopically
enhanced category theory, based on Alexander Grothendieck’s idea of a “derivator”. This work aims to make abstract structures more flexible and computationally powerful, offering practical tools for researchers working across geometry, topology and mathematical physics.

## Event information

These two lectures will both take place in the seminar room of the London Institute for Mathematical Sciences, which is on the second floor of the Royal Institution. The first, at 1:00 pm on Monday, 24 November, is held jointly with Imperial College London as part of the MAGIC algebraic geometry seminar series. The second is at 3:00 pm on Friday, 28 November. 

In two lectures, Dmitry Kaledin explores progress towards a non-commutative Hodge theory and a theory of homotopically enhanced categories.

Prof. Ran Tessler explores how the amplituhedron offers a geometric framework to understand the surprising connections between scattering amplitudes in N=4 Super Yang–Mills theory and cluster algebras. These links are not only conceptually rich but also essential for practical amplitude calculations. He presents a key cluster relation, its proof, and a new conjectural generalisation expressed in the language of operads.

[Prof. Ran Tessler](https://www.weizmann.ac.il/math/tessler/home) is a mathematician at the Weizmann Institute whose work bridges geometry, combinatorics and physics. He studies scattering amplitudes, amplituhedra and their links to cluster algebras, exploring the deep structures that connect mathematics and quantum theory.

Dr Brandon Rayhaun shows how the irreversibility of renormalisation group flow, combined with anomalies—including those in the space of coupling constants—can be used to constrain the infrared phases of defects in well-known quantum field theories. As an illustration, he presents new evidence for a conjectural “spin–flux duality”, which describes how line operators map across particle–vortex duality in 2+1 dimensions.

[Dr Brandon Rayhaun](https://www.ias.edu/scholars/brandon-rayhaun) is a Leinweber Physics Member at the Institute for Advanced Study. He did his PhD at Stanford.

When Richard Feynman died in 1988, his last blackboard bore a curious note to himself: “To learn: Bethe Ansatz.” The Bethe Ansatz, introduced by Hans Bethe in 1931, is a method for finding the spectra of Hamiltonians in quantum integrable systems such as the Heisenberg magnet. For decades it helped produce astonishing results and conjectures, though no one quite knew why it worked.

In this talk, Prof. Edward Frenkel revisits this enduring mystery. In collaboration with Boris Feigin and Nicolai Reshetikhin, he reinterpreted the Bethe Ansatz through the lens of the geometric Langlands correspondence, expressing its spectra in terms of mathematical objects known as opers. This framework led to powerful generalisations involving q-characters of quantum affine algebras and q-opers, bridging quantum physics and modern geometry.

Prof. Frenkel explores these ideas and reflects on why the Bethe Ansatz—an old key to new symmetries—still stood at the top of Feynman’s list.

## Event information
The event takes place on Thursday 11 December at the London Institute for Mathematical Sciences, which is on the second floor of the Royal Institution.

Edward Frenkel illuminates Feynman’s final quest—to learn the Bethe Ansatz—with fresh insights from the geometric Langlands correspondence.

By analytically studying the repeated composition of simple Boolean functions, Dr Thomas Fink uncovers the spontaneous emergence of a law of parsimony. It is the first exact solution of a nontrivial input-output map, and suggests an explanation for why neural networks are biased towards simplicity in the models that they generate. The general result applies whenever composition of more than one input occurs.

To many, science appears as a kind of modern magic—the only magic that works. In the Soviet Union, an officially atheist state, science was elevated even further, becoming a substitute for religion.  The DAU project began as a biopic of Lev Landau, the Nobel Prize–winning physicist and icon of Soviet science. But it evolved into something far more ambitious: a vast social and artistic experiment exploring what it means to be Soviet, to be modern and to believe in science. 

As part of the project, hundreds of participants lived and worked inside a reconstructed Soviet research institute, their lives filmed in an unprecedented exploration of the scientific worldview. Among the works born of the ongoing project was *DAU. Natasha*, which won the Silver Bear at the Berlin International Film Festival in 2020.

In this talk, Prof. Dmitry Kaledin offers a rare insider’s view of DAU—from its portrayal of Soviet scientific culture to its deeper inquiry into the meaning of science itself.

Matter and fundamental forces are governed by non-abelian gauge theories and general relativity. These theories look very different, but recent research has uncovered the “double copy”—an exact correspondence between their mathematical structures. Prof. Chris White reviews its theoretical origins and practical uses, highlighting links to string theory, exotic field theories, and open questions in pure mathematics.

[Prof. Chris White](https://www.seresearch.qmul.ac.uk/cfp/people/cwhite/) is a theoretical physicist at Queen Mary University of London. He studied at the University of Cambridge, before holding positions in Amsterdam, Durham and Glasgow. His research focuses on theories of particle physics, and their relationship to gravity and beyond.

Plato was fascinated by the intricate relationship between science and music. We have explored it, too, in events focusing on the mathematics of the violin and the bagpipes. Now we are delighted to welcome to our rooms a Steinway & Sons grand piano, which is generously being lent to us by the Ukrainian concert pianist Sasha Grynyuk.  

This Steinway Model B grand piano has a distinguished lineage. Before Grunyuk, it belonged to the concert pianist and teacher Noretta Conci-Leech, who studied under Arturo Benedetti Michelangeli. It has also been played by such virtuosi as Evgeny Kissin, Claudio Abbado, Maurizio Pollini, Antonio Pappano and Alfred Brendel. Now it occupies our seminar room, which was once the study of Michael Faraday.

Since it arrived in July, the Faraday grand, as we’re calling it, has been played by, among others, our trustee Ben Delo and, frequently, our fellow Juven Wang. We have also enjoyed recitals from Grynyuk himself and look forward to more in the future.

Matrix models—systems in which randomness and algebraic structure meet—play a central role across theoretical physics and mathematics. Often seen as zero-dimensional analogues of field theories, they also lie at the heart of deep connections linking string theory, integrability, quantum gravity, Yang–Mills theory, combinatorics, geometry, and representation theory.

In this four-part lecture series, Dr Levkovich-Maslyuk provides a guided, pedagogical journey through the subject: starting with motivation and definitions, through reduction to eigenvalue form, to continuum limits and spectral curves, and finally to orthogonal polynomials, phase transitions, and links to two-dimensional gravity. Along the way he sketches the broader vista of loop equations, topological recursion, and integrability. The series offers both newcomers and seasoned theorists a unified and illuminating view of how matrix models continue to shape modern research.

Introduction to matrix models

Our universe is chiral—it knows its left from its right. Yet theories with chiral fermions are notoriously difficult to simulate. Dr Rishi Mouland applies powerful symmetry-based techniques to derive the phase diagrams of strongly coupled two-dimensional gauge theories, revealing new, readily simulable models that realise chiral infrared phases and illuminate fresh pathways to understanding the physics of our universe. 

[Dr Rishi Mouland](https://mou.land/) is a postdoc at Imperial College London. He did his PhD at King’s College London followed by postdoctoral research at Cambridge. His interests range from generalised symmetries in strongly coupled gauge theory to quantum gravity and the holographic bootstrap.

Rishi Mouland demonstrates how generalised notions of symmetry can be used in novel ways to probe strongly coupled quantum field theories.

In later life, Alexander Grothendieck was captivated by simple graphs encoding holomorphic maps to the sphere. He called them dessins d’enfants—“children’s drawings”. Decades earlier, Gerard ’t Hooft noted that the 1/N expansion in gauge theory mirrors the genus expansion in string theory. Dr Edward Mazenc shows how recent work on AdS/CFT reveals Grothendieck’s insight as the simplest form of gauge–string duality.

[Dr Edward Mazenc](https://www.edwardmazenc.com/) is a research fellow at ETH Zurich. He did his PhD at Stanford and was a Kadanoff Fellow at the University of Chicago.

Integrable models in 1+1 dimensions allow exact solutions of scattering problems and often the complete derivation of spectra. But these models raise a deeper question: what really are the particles being scattering? In low dimensions, unexpected phenomena emerge. Prof. Alessandro Torrielli explores spin and statistics in 1+1 dimensions, delving into one manifestation of this strange behaviour in AdS_3 string theory.

The latest advances in quantum computing are pushing the limits of our ability to describe and simulate out-of-equilibrium dynamics of quantum systems. Dr Alexey Milekhin introduces powerful theoretical tools to address these problems, focusing on the Sachdev–Ye–Kitaev model and the emerging framework of “entanglement in time”, an information-theoretic approach designed to probe dynamical properties of quantum systems.

Quantum dynamics meets quantum information

Since the discovery of the thermodynamics of black holes, a key challenge has been uniting statistical mechanics with gravity and quantum information. Prof. Ginestra Bianconi proposes a new “Gravity from Entropy” action for gravity, with a Lagrangian given by the geometric quantum relative entropy. This framework recovers Einstein’s equations in the low-energy, small-curvature limit and predicts modified gravity beyond.

[Ginestra Bianconi](https://webspace.maths.qmul.ac.uk/g.bianconi/) is a professor at Queen Mary University of London, an APS Fellow and member of the European Academy of Sciences. She is recognised for pioneering work in statistical mechanics and theoretical physics, especially on how topology shapes dynamics in complex networks.

Ginestra Bianconi illustrates her novel approach to quantum gravity, which is grounded in statistical mechanics and information theory.

The history of “artificial intelligence” is the history of an overhyped intellectual brand that has only very recently come to signify a set of deployable technologies with broad application and clear, if somewhat horrifying, purposes. Since its debut in 1955 the AI brand has been attached to a rotating cast of technologies with only loose connections to each other or to cognition, none of which has yet come close to delivering on the promise of creating computer systems with human-like intelligence. One AI insider characterized the story of AI as “the history of failed ideas.” Yet in the process of failing, early AI researchers made vital but incidental contributions to the development of computer technology and computer science.

In this seminar, Thomas Haigh explores where the AI brand came from, why it was so attractive to researchers and sponsors, and how artificial intelligence institutionalised as a subfield of computer science through research labs, curricula, textbooks and professional associations. Haigh also documents continuities and discontinuities between our own moment and earlier cycles of AI hype and disillusionment.

Artificial Intelligence: the brand that wouldn’t die

The story of science is often told as a series of flashes of insight, enjoyed by heroic figures such as the Royal Institution’s Sir Humphry Davy and Michael Faraday. Yet in reality, innovation is rarely so simple or dramatic.

Drawing on examples from the history of the Royal Institution, as well as insights from his recent book, *Like: The Button that Changed the World*, London Institute Trustee Martin Reeves makes an original case for how scientific breakthroughs really happen. He demonstrates that most are not the result of eureka moments, but a combination of iteration, collaboration and, strangest of all, serendipity. With the aid of vivid demonstrations in the tradition of the Royal Institution, he explains why this does not just mean surrendering to chance. On the contrary, he hones in on the mathematical basis for serendipity—hidden patterns in the history of discovery—and shares the strategies that innovative businesses and research centres use to harness it.

Prof. Mark Gross discusses the notion of scattering diagrams, a powerful means of encoding often very complex wall-crossing data in a wide range of geometric problems. Originally developed in the foundational work of Kontsevich and Soibelman, scattering diagrams have since emerged in many different contexts, including mirror symmetry, cluster algebras, wall-crossing for moduli spaces of sheaves and theoretical physics.

Symmetry is a powerful organising principle, enabling remarkably precise, all-order predictions about the behaviour of quantum systems. Dr Christian Copetti explains how generalised symmetries act on boundary conditions and defects, and uses these ideas to constrain key features of (1+1)d scattering amplitudes, such as crossing symmetry, and shows how ultraviolet defects may be screened by bulk degrees of freedom.

[Dr Christian Copetti](https://www.maths.ox.ac.uk/people/christian.copetti) is a postdoc at Oxford University. He did his PhD at IFT in Madrid and then held a research position at SISSA in Trieste.

Prof. Darryl Holm shows how geometric mechanics uses Lie–Noether symmetries of Hamilton’s principle to derive momentum maps and Euler–Poincaré equations, with variables that evolve by coadjoint motion. This motion imparts common features to their solutions, demonstrating how geometric mechanics offers a way to study symmetry breaking and the multi-scale challenges arising in modern investigations of dynamics in nature.

Artificial intelligence is no longer confined to crunching numbers—it is beginning to propose original theorems, sketch proofs and reveal new and unexpected patterns in the abstract world of mathematics. Speaking in the iconic lecture theatre of the Royal Institution, Prof. Yang-Hui He—one of the pioneers of AI-assisted discovery— explores how machine learning is transforming both the practice and philosophy of mathematical research.

Drawing on his own leading-edge work, alongside insights from a recent gathering in Berkeley where mathematicians challenged a powerful AI chatbot to solve problems designed to resist automation, Prof. He traces the emergence of a new form of mathematical exploration. Describing his AI-assisted discovery, with colleagues, of “murmuration” patterns in elliptic curves, Prof. He shows how, by fusing human intuition with computational power, this partnership is reshaping research and redefining the creative boundaries of the field.

Symmetries play a central role in mathematics, linking algebra and geometry. Groups and algebras of symmetries provide geometric realisations of respective abstract structures, while their algebraic properties lead to unexpected geometric insights. In this session, three speakers showcase the rich interplay between these two worlds.

First, Prof. Travis Schedler of Imperial College outlines a programme to classify crepant resolutions of moduli spaces—especially Nakajima quiver varieties—revealing new structures beyond the projective case.

Next, Prof. Evgeny Feigin from Tel-Aviv University describes the geometry of the graph closure of a birational map from projective space to a Grassmannian, including its fibres and embeddings into projectivized cyclic representations of a degenerate Lie algebra.
Finally, Prof. Konstanze Rietsch of King’s College London explores new tropical versions of parametrisations for totally positive Toeplitz matrices, offering a unified perspective on their roles in representation theory and mirror symmetry, and connecting them to the quantum cohomology of flag varieties and canonical bases.

Prof. Ed Segal of UCL discusses derived equivalences and autoequivalences arising from wall-crossing phenomena on Calabi-Yau toric varieties. Mirror symmetry relates these to monodromy around the Gelfand–Kapranov–Zelevinsky's discriminant locus. He conjectures that intersection multiplicities in the discriminant equal the multiplicities appearing in semi-orthogonal decompositions, proving the conjecture in some cases.

The Special Relationship between America and Britain has never been more special than in science. Yet now that the number of scientists looking to leave America is on the rise, what is Britain doing to support them? In a recent [article](https://lims.ac.uk/perspectives/the-most-valuable-cargo/) in *The Spectator*, the Director of the London Institute, Dr Thomas Fink, argued that we should create new scientific posts earmarked for Americans, and view the coming wave of talent not as a prospective win for Britain but as part of the long-term scientific alliance between our two countries.

In this event, Prof. Thomas Rosenbaum, the President of Caltech, will sit down with James Arroyo OBE, the Director of the Ditchley Foundation, for a conversation about how British science can respond to recent proposed cuts to the government funding of science in America.

Ageing is thought to be an inevitable consequence of breakdowns in how genetic information is processed. But mounting experimental evidence suggests aging can be slowed. To resolve this, Dr Thomas Fink, Director of the London Institute, derives a mortality equation that governs the dynamics of an evolving population with a given maximum age. His solution shows that programmed ageing cannot confer a long-term benefit.

Thomas Fink unveils a mathematical model showing programmed aging cannot be favoured by natural selection, even in a shifting environment.

Martin Reeves, Senior Partner and Managing Director at the Boston Consulting Group and Trustee of the London Institute, took up the Great Highland bagpipe during the coronavirus pandemic. In this talk and performance, he delves into the noble history and mathematical structure of the instrument. With lyrical insight and expert playing, Mr Reeves shows why the bagpipe is as rich in logic as it is in tradition and sound.

Martin Reeves explores the surprising harmony between the music and maths of the Great Highland bagpipe—complete with a live demonstration.

Prof. Michael Douglas of the Center of Mathematical Sciences and Applications at Harvard explores the frontiers of artificial general intelligence, which some experts now anticipate within 2–3 years. Drawing lessons from past milestones—such as when computers surpassed humans in chess—he discusses the development of mathematical copilots and conceptual systems that could soon enable autonomous, machine-led research.

Prof. Michael Douglas examines how advances in AI may soon lead to autonomous systems capable of making genuine mathematical discoveries.

Prof. Joseph Conlon from Oxford University will explore the largely unconstrained epoch between inflation and nucleosynthesis, spanning more than 30 orders of magnitude in time. String cosmology suggests this era may include moduli-dominated phases—such as kination, tracker, and matter epochs—and he introduces a novel percolation-based scenario for the formation of cosmic string networks in the very early universe.

Prof. Joseph Conlon outlines how string theory suggests new equations of state that may describe the physics of the very early universe.

Artificial Intelligence is revolutionising our understanding of life. The DeepMind programme tackling the protein folding problem, AlphaFold, ushered in a new era for protein structure prediction and earned its creators last year’s Nobel Prize in Chemistry. But that was just the beginning.

Speaking in the historic lecture theatre of the Royal Institution, Dr Mikhail Burtsev gives a tour of the leading-edge biological applications of AI, including his own, that are now making complex biological insights more accessible than ever before. AI chatbots such as ChatGPT are trained on human language, but these new AI models are instead fed billions of real DNA sequences, allowing them to perform astonishing feats like designing new biological molecules—or even whole new bacterial genomes. Their ultimate goal is to solve perhaps the most fundamental problem in all of biology—reading and understanding life’s genetic blueprint from beginning to end.

## Event information

This event, which includes research supported by the Khodorkovsky Foundation, takes place in the lecture theatre at the Royal Institution. London Institute guests are invited to join the speaker after for drinks in our private rooms.

Mikhail Burtsev explains how artificial intelligence is helping to decipher genomes in the Royal Institution’s iconic lecture theatre.

Decoding life with AI

Dr Simon Telen leads the numerical algebraic geometry group at the Max Planck institute for Mathematics in the Sciences in Leipzig. He studies toric amplitudes—rational functions inspired by the scattering amplitudes of particle physics but associated to arbitrary simplicial polyhedral fans. He describes the algebraic properties of such amplitudes and their zero loci, exploring their Fano schemes and singular loci.

Simon Telen presents his discovery of a new connection between polynomials inspired by particle physics and classical algebraic geometry.

Mr Pinardin is a PhD student at the University of Edinburgh. He addresses the problem of describing the linearizable subgroups of the plane Cremona group, the group of birational self-maps of the projective plane. Drawing on work with Drs Arman Sarikyan and Egor Yasinsky, Mr Pinardin gives a complete solution to this problem, equivalent to the question of G-equivariant rationality, over the field of complex numbers.

Antoine Pinardin presents a complete description of the linearisable subgroups of the plane Cremona group over the field of complex numbers.

Dr Matthew Buican is a Reader in theoretical physics at Queen Mary University of London. He describes a universal relevant deformation that takes local unitary 3d N=4 superconformal field theories to topological quantum field theories, explaining, for example, how Abelian mirror symmetry is related to generalisations of level-rank duality, as well as some results that arise as a result of ’t Hooft anomaly matching.

Symmetry plays a fundamental role in quantum systems, shaping their dynamics, enforcing selection rules and enabling the development of new algorithms for nascent quantum computers. In recent years, novel forms of symmetry, known as generalised global symmetries, have been discovered in a wide range of quantum systems. These include non-invertible symmetries and higher-group symmetries, which go beyond traditional notions of symmetry and provide new insights into the structure and behavior of quantum theories.

In this series of four lectures, Dr Hsin will explore the role of these symmetries in various quantum systems and their applications, such as their ability to constrain low-energy dynamics. The lectures will examine examples from quantum mechanics, gauge theories and lattice models, focusing on ordinary symmetries, higher-form symmetries and non-invertible symmetries, shedding light on their profound impact in modern physics.

## Event information

This is a four-part lecture series from LonTI. Lectures are on Mondays at 10:30 am in the Tyndall seminar room at the London Institute, on the second floor of the Royal Institution, followed by drinks and snacks onsite. To register and attend, please visit lonti.weebly.com.

Two seminars discuss new applications of AI to quantum theory. Prof. Koji Hashimoto of Kyoto University shows how a neural network can generate arbitrary Feynman path integrals as a consequence of the universal approximation theorem. Afterwards, Dr Akio Tomiya of Tokyo Woman's Christian University introduces a transformer architecture designed for lattice QCD that outperforms existing gauge covariant neural networks.

In two consecutive talks, Prof. Koji Hashimoto and Dr Akio Tomiya discuss applying machine learning to problems in quantum field theory.

AI for QFT

Prof. Konstantinos Zoubos from the University of Pretoria will explain how Lie groupoids and their twists are the appropriate framework to discuss the true symmetries of N=2 supersymmetric orbifold gauge field theories in the planar limit. These hidden symmetries provide an explanation for certain non-trivial relations between QFT observables and point to possible integrable structures associated to these theories.

Prof. Konstantinos Zoubos will use Lie groupoids and their twists to uncover hidden symmetries of supersymmetric orbifold field theories.

Quantum Chromodynamics has been a profound source of inspiration for theoretical physicists, driving the development of key concepts such as string theory, effective field theories, instantons, anomalies, and lattice gauge theories. In this four-part lecture series, Dr Guerrieri will explore two distinct regimes of Quantum Chromodynamics—its infrared and ultraviolet limits—and the theoretical tools used to study them.

In the infrared regime, where perturbative techniques break down, Effective Field Theories provide a powerful framework. Here, Dr Guerrieri will introduce the pion EFT as a tool to study non-linearly realized symmetries and soft theorems. In the ultraviolet regime, where Quantum Chromodynamics becomes amenable to perturbative analysis, he will discuss the Operator Product Expansion and renormalization group equations, focusing on their application to deep inelastic scattering, a cornerstone in the discovery of quarks and gluons.

Dr Alex Davies leads Google DeepMind’s initiative for AI and mathematics. In a discussion with our scientists and staff, he gives his take on AlphaGeometry, which solves hard but known problems, and the possibilities for AI-assisted discovery of new conjectures. He also considers the scope and limits of automated theorem proving, and how the human mind makes shortcuts that machines must spell out pedantically.

In 1974, Stephen Hawking calculated that black holes emit particles, eventually evaporating away completely. This was the origin of the black hole information paradox, in essence a conflict between quantum theory, which demands that information on particle interactions cannot be lost, and general relativity, which predicts that once a particle crosses the event horizon, no information can ever escape.

In this four-part series, Dr Tarek Anous will give a technical introduction to the paradox. Beginning with a review of quantum path integrals, he will outline the laws of black hole thermodynamics before deriving the Unruh effect, which predicts that a detector with a uniformly accelerated observer measures a temperature related to the observer’s proper acceleration. This will be followed by a session on classical and quantum information theory. The series concludes with a toy model of the paradox and a review of what is left to understand.

In this seminar, Dr Wang will explore key problems in high energy theoretical physics. First, he will discuss the puzzle of why there are three families of quarks and leptons in the Standard Model. He will argue that a dimensional reduction of the Standard Model to a 2-dimensional conformal field theory with chiral central charge c-=0 mod 24 is both modular invariant and framing anomaly free. This result, he will show, is constrained by the Hirzebruch signature theorem, gravitational Chern-Simons theory, and 3 E8 quantum Hall states.

Secondly, Dr Wang will propose a new model of unification constructed from a mod 16 nonperturbative global anomaly cancellation that adds a symmetry-extended anomalous topological quantum field theory to the Standard Model. With this fresh approach to physics beyond the Standard Model, Dr Wang will address long-standing questions relating to the properties of neutrinos, the composition of Dark Matter and the cause of leptogenesis.

Dr Juven Wang proposes novel solutions to open problems in high-energy phenomenology via new analogies from modern ultra quantum matter.

Simon Norton, who died in February 2019, is best remembered by mathematicians for his remarkable contributions to group theory. A child prodigy, Norton earned a First in mathematics from the University of London while he was still studying at Eton College.

Later, at the University of Cambridge, he would work with John Conway, co-authoring the ATLAS of Finite Groups, the definitive catalogue of different types of symmetry. The pair’s paper on monstrous moonshine, published in 1979, proposed an unexpected deep connection between the monster group and the j-function. Seemingly far-fetched, the conjecture was proved in 1992 by Richard Borcherds and is recognised as one of the great unifying conjectures in modern mathematics.

In the second Simon Norton Lecture, Prof. Leonard Soicher will explain what the monster is and its importance before describing Norton’s research on the internal structure of the group and its subgroups. He will also discuss his work with Norton and Conway on the projective plane presentation for the bimonster. We are grateful to Simon’s family for their generous support of this lecture.

The London Institute was founded in 2011 and incorporated on 10 February. This marked the birth of Britain’s only independent research organisation in the physical sciences. The date is also the feast day of St Scholastica, who lived in Italy in the 6th century and is the patron saint of learning and Benedictine nuns.

One of the few surviving stories about St Scholastica is that one night, after her brother St Benedict had dined with her, he rose to leave. She prayed to God to make it rain, so he would be compelled to stay and they might continue talking. So it came to pass. St Scholastica is therefore indelibly associated with evenings filled with good conversations, which continue into the night.

To celebrate our founding and our belief in the value of community, we hold an annual St Scholastica’s Feast in our rooms. This formal dinner is for our scientists and staff and a handful of distinguished guests. It takes place on a Friday near the day of our incorporation.

## Event information

The dinner is at 7 o’clock on Friday, 14 February in our rooms on the second floor of the Royal Institution. Dress is black tie. We meet in the Old Post Room, then head to dinner in the Faraday Room and dessert in the Bragg Room, followed by drinks in the Old Post Room.

We hold an annual formal dinner in our rooms, to mark the anniversary of our founding and affirm our belief in the importance of community.
