Abstract:
In “Eve’s Byte of the Apple”, Sandi Toksvig will be taking an alternative look at the evolution of information, at how the knowledge of women and about women is encoded, and what comes from those codes. Since 2023 Sandi has been a Bye-Fellow at Christ’s College, Cambridge working on The Mappa Mundi Project, creating a global interactive digital platform telling women’s stories worldwide. In this lecture, she considers how the evolution of information technology has been historically biased against women, continuing that bias to the present day. Most importantly, she asks what might be done about it.
Biography:
Sandi Toksvig was born in Copenhagen, Denmark but grew up travelling the world. After graduating with a first-class degree from Cambridge, Sandi began a career on stage, television and radio. As a political and women’s rights activist, she was co-founder of the Women’s Equality Party in 2015. Sandi has written stage plays, journalism and over 25 books including fact and fiction for both children and adults. Her latest novel Friends of Dorothy was published in 2024.

Thu 13 Feb 17:00: Algebraising foundations of elliptic curves
Elliptic curves are one of the simplest non-trivial objects in algebraic geometry, which are pervasive in modern number theory, but also see applications in point counting algorithms and public key cryptography. Due to their geometric nature, formalising a working definition typically requires a lot of technical machinery, let alone any non-trivial results. Yet, the Lean community has managed to formalise two of the most fundamental theorems in the theory of elliptic curves, with scope for many more projects. In this talk, I will explain these theorems, and how we inadvertently discovered new proofs in our formalisation attempts.

Tue 25 Feb 14:00: Can kernel machines be a viable alternative to deep neural networks?
Deep learning remains an art with several heuristics that do not always translate across application domains. Kernel machines, a classical model in ML, have received renewed attention following the discovery of the Neural Tangent Kernel and its equivalence to wide neural networks. I will present 2 results which show the promise of kernel machines for modern large scale applications. 1. Data-dependent supervised kernels: https://www.science.org/stoken/author-tokens/ST-1738/full 2. Fast scalable training algorithms for kernel machines: https://arxiv.org/abs/2411.16658

Mon 10 Mar 11:00: LMB Seminar - One or two membranes? Investigating the transition between monoderm and diderm cell envelopes across the Tree of Bacteria - IN PERSON ONLY
The cell envelope is one of the oldest and most fundamental biological structures, and a major target of antimicrobials. Bacteria can have radically different envelopes, containing either one (monoderm) or two (diderm) membranes, generally known as Gram-positives and Gram-negatives. How and why such dramatic transition occurred has remained a major open question in evolutionary biology. In my talk, I will present recent data where we addressed this issue by merging large-scale computational analyses with experimental evolution using a new bacterial model at the interface between diderms and monoderms. Our results challenge established paradigms and propose a hypothesis on how the monoderm/diderm transition might have occurred.

Fri 14 Feb 18:00: Modelling for the Budding Mathematician
Both pure and applied mathematics are about modelling: one approximates concepts, while the other is concerned with ‘the real world’. Either form must contend with the inherent difficulties of the enterprise.
This talk will discuss what ‘modelling’ entails and how the tools of category theory provide natural ways to tackle the associated challenges. This is intended as a gentle introduction to categorical thinking, and no prior background is assumed. If time permits, I will also sketch an elegant new approach to modelling complex systems based on the theory of double categories and how it is connected to assume-guarantee reasoning.
