  • Liz Fearon: Co-producing mathematics with the public
    We may not notice it, but mathematics impacts our lives on a daily basis.Ā Mathematical modelsĀ inform policy decisions around the economy andĀ public health. They are used to understandĀ climate changeĀ and how to respond to it. They are vital in the design ofĀ public buildingsĀ and spaces. They are even used to try andĀ prevent crime.Ā  It seems reasonable, then, that the mathematical models should reflect people's interaction with each other and their environment, and that they should take account of people's perspectives and priorities. In this episode ofĀ Maths on the MoveĀ we talk toĀ Liz Fearon, an epidemiologistĀ  at University College London, about aĀ pioneering new projectĀ which aims to involve people in the production of mathematical models from the start, treating them as valued and equal members of the research team. Liz tells out about the motivation behind the project, how it works, and what she hopes to achieve. To find out more about topics mentioned in this podcast see: Co-production of mathematical models — the article accompanying this podcast The website of the COMMET project Disease modelling for beginners — our introduction to some basic concepts in infectious disease modelling The inequalities of COVID-19 — our article exploring the role of the pandemic in amplifying social inequalities Tracing mpox — our article about modelling the spread of mpox. This podcast is part of ourĀ collaborationĀ withĀ JUNIPER, the Joint UNIversity Pandemic and Epidemic Response modelling consortium. JUNIPER comprises academics from the universities of Cambridge, Warwick, Bristol, Exeter, Oxford, Manchester, and Lancaster, who are using a range of mathematical and statistical techniques to address pressing questions about the control of COVID-19.

  • Living proof: Hunting through higher dimensions with Zhouli Xu
    On May 30th 2024 seminar goers at Princeton University witnessed a thrilling moment. The mathematicianĀ Zhouli XuĀ of the University of California, LA, announced that, together with colleagues he had sorted out the 126th dimension. Not in general, but in regards to a problem that has taunted mathematicians since the 1960s. The problem involves strange shapes and is called theĀ Kervaire invariant problem, after the mathematician Michel Kervaire. In this episode ofĀ Maths on the MoveĀ Zhouli takes us on a trip into higher dimensions, giving us a gist of what this long-standing problem is all about and retracing some of the long, and sometimes arduous, journey towards a proof. We met Zhouli when he visited our neighbours at theĀ Isaac Newton institute for Mathematical SciencesĀ (INI) in Cambridge to take part in a research programme calledĀ Equivariant homotopy theory in Context.

  • Brainstorming AI with Maths4DL
    The capabilities of artificial intelligence may appear to be galloping ahead, but there are still many challenges that need to be solved. Last month we joined members of the Maths4DLĀ research project for aĀ hackathon — an intensive two-day brainstorming session designed to figure out how one might teachĀ machine learning techniques for solving differential equationsĀ and how best to test those techniques. In this episode ofĀ Maths on the Move,Ā Maths4DL membersĀ Yolanne LeeĀ from University College London,Ā Georg MaierhoferĀ from the University of Cambridge, andĀ Chris Budd OBE from the University of Bath tell us all about the hackathon, the science behind it, and what it was like to participate in those ambitious but exciting 48 hours. For a brief introduction to machine learning seeĀ Maths in a minute: Machine learning and neural networksĀ and for a brief introduction to differential equations seeĀ Maths in a minute: Differential equations.

This content is part of our collaboration with theĀ Mathematics for Deep LearningĀ (Maths4DL) research programme, which brings together researchers from the universities of Bath and Cambridge, and University College London. Maths4DL aims to combine theory, modelling, data and computation to unlock the next generation of deep learning. You can see more content produced with Maths4DLĀ here.

  • Meet your digital twin
    Imagine we could have a digital version of our entire body which could help us, and our doctors, decide what life style is good for us, predict which diseases we might get, and how to best treat them? In short, what if we could all have our very own digital twin? The idea isn't quite as sci-fi as it sounds. A gigantic scientific effort called the Physiome ProjectĀ is about piecing together a mathematical description of the entire physiology of the human body. Once this has been achieved to a sufficient level digital twins will be a spin-off. In this podcast we revisit an interview we did back in 2019 withĀ Steven Niederer, who was then Professor of Biomedical Engineering at King's College London but has since moved to a new position at Imperial College London as Chair of Biomedical Engineering. Niederer told us about the physiome project, about how the fitbits many of us own are a very first step towards a digital twin, and about how you can model individual human organs such as the heart. We also challenge ourselves to explain differential equations in one minute. You can find out more aboutĀ maths and medicine,Ā differential equationsĀ andĀ mathematical modellingĀ onĀ Plus. We met Niederer in 2019 when he helped to organise aĀ research programme at the Isaac Newton Institute for Mathematical Sciences in Cambridge. The music in this podcast comes from the artistĀ Oli Freke. The track is calledĀ Space Power Facility.

  • Living proof: The meaning is in the arrows with Adina Goldberg
    In this podcast we hope to give you some interesting information. Ā This information is encoded in terms of 0s and 1s – the classicalĀ bitsĀ in your computer or phone. Ā But what if instead we were using a quantum computer? Ā Then we'd be dealing with quantum bits, orĀ qubits, opening up exciting new possibilities. Ā AndĀ quantum information theoryĀ is the area of mathematics that explores how we can do that.Ā  Adina GoldbergĀ was one of the participants at a recentĀ research programmeĀ in this area at theĀ Isaac Newton Institute for Mathematical SciencesĀ (INI). In this episode ofĀ Living proof, our podcast produced in collaboration with the INI, we speak to Adina about her work and how her intriguing motto – "the meaning is in the arrows" – applies to her research, her career path, and the way she looks at life. You can find out more about quantum information in thisĀ short introductionĀ and delve into the details of information theory in thisĀ collection of content. Ā  Make sure you visitĀ Adina's websiteĀ to find out more about her work and her fascinating career. Since we recorded this podcast Adina has finished her PhD – congratulations Dr Goldberg!
