The fluid mechanics in your daily life
Many specialties of physics affect the way you live your life. Electromagnetism governs your internet access and how your breakfast burrito cooks in the microwave. Acoustics controls how you should select your seat in a lecture theatre. Gravity impacts how much pain you will endure the next time you fall of your bike. Thermodynamics explains how your fridge works.
In this talk, I will take you through the many aspects of your daily life, many of them seemingly mundane, which are governed by fluid mechanics. At the end of the talk, I am hoping that members of the audience will appreciate how viewing your daily life with a applied mathematician’s eye can reveal a lot of complex – and fun – scientific problems.

Green's functions: from physics to analysis
Green's functions are ubiquitous throughout physics and applied mathematics. I will discuss some the history surrounding them, including Green's "physical" proof of the existence of the Dirichlet Green's function for the Laplacian. After this I'll move onto fundamental solutions for constant coefficient partial differential operators and some proofs of the Malgrange–Ehrenpreis theorem. I hope to keep technicalities to a minimum, so all welcome.
28th February 2020 — Prof. Gabriel Paternain (University of Cambridge)
The non-abelian X-ray transform
I will describe the mathematics that underpins new experiments designed to measure magnetic fields inside materials by shooting them with neutron beams from different directions, like in a CT scan. The problem is packed with some beautiful geometry and analysis, where the star of the show is a matrix in SO(3) obtained by solving a suitable linear ODE along straight lines in the plane. Very little will be needed to formulate and understand the problem: IA Differential Equations and Groups.

How Statistics is changing the world
Even when data were relatively scarce in the 20th century, Statistics was already having enormous impact: think of the increase in global life expectancy due to randomised controlled trials, or the effect of the design of experiments on agricultural crop yields. These days, data are ubiquitous, and the potential of statistical methods is even greater, from driverless cars to medical imaging, and from climate change to cancer genetics. This talk will be a whistlestop tour of some of these developments, designed to highlight the demand and opportunities for well-trained, modern statisticians.
