An annual tradition, held by the TMS, in which a team of freshers test their lying capabilities against a team of other students in a reconstruction of the cult British TV show.

High-dimensional data and the Lasso
Dr Rajen Shah (DPMMS) 

How would you try to solve a linear system of equations with more unknowns than equations? Of course, there are infinitely many solutions, and yet this is the sort of the problem statisticians face with many modern datasets, arising in genetics, imaging, finance and many other fields. What’s worse, our equations are often corrupted by noisy measurements! In this talk I will introduce a statistical method called the Lasso that has been at the centre of the huge amount of research that has gone into solving these problems.

Is classical physics deterministic? – Professor Mihalis Dafermos (DPMMS)

Details for our next talk – on classical physics – are given below.
Is classical physics deterministic?
Professor Mihalis Dafermos (DPMMS)
Monday 28th October, 8:30PM, Winstanley Lecture Theatre
We are all taught that quantum mechanics suffers from lack of determinism. But classical, i.e. non-quantum, physics is supposedly deterministic: complete knowledge of initial conditions in the present uniquely determine the future. This notion of determinism is often associated with the name of Laplace, and finds a mathematical realisation in the standard existence and uniqueness theorems for differential equations. But is it really true that the classical equations of mathematical physics uphold this notion? This talk will explore one of the most spectacular ways that Laplacian determinism can in fact fail.

Our next talk will be given by Dr Roland Bauerschmidt (DPMMS). Note that it will start at 9pm this week – an exception to the usual.
The Universality Phenomenon
Dr Roland Bauerschmidt (DPMMS)
Monday 21st October, Winstanley Lecture Theatre, 9 PM

Many complex systems in mathematics and physics show universal behaviour, i.e., behaviour that is independent of the details of the system. I will illustrate this universality phenomenon in several examples, some well-understood, some still mysterious.

We are all used to thinking about shapes in 2 or 3 dimensions. But what about in 4 dimensions? Or even n dimensions, where n is large?

How to Build Mathematical Models – Professor Eric Lauga (DAMTP)

Leave a reply

Our final talk – yes, final talk! – of this year is given by Professor Eric Lauga. Details below, hope to see lots of you there!

How to Build Mathematical Models
Professor Eric Lauga (DAMTP)
11 March, Winstanley Lecture Theatre, 8:30PM
Everybody knows what “Mathematics” is but ask around and you will quickly realise that nobody really knows what “Applied Mathematics” means. In this talk I will use research drawn from the world of physics and biology to convey what it means to be an applied mathematician. In particular, I will explain how one goes about building a mathematical model, what approximate solutions are and why sometimes you don’t have a choice and need to use a computer.
