TMS Centenary Dinner – Important Information

This academic year marks the 100th anniversary of the Trinity Mathematical Society. As a result, our usual annual dinner has been upgraded to the TMS Centenary Dinner in Trinity’s Great Hall. This will take place at 7:30PM on Saturday 23rd February, following the Centenary Symposium, and given this special occasion, we shall invite both members of the TMS who are resident junior members of the University and past members (alumni) to raise our glasses to the first 100 years of the UK’s oldest extant subject society.

As opposed to previous years, tickets will be allocated via a ballot rather than on a first-come first-serve basis, and will cost £20. There will be around 100 tickets issued in total for current members, and you are cordially invited to apply at: https://alumni.trin.cam.ac.uk/events/events-2019/tms-2019.

Applications are open and will close on Friday 8th February at 1PM. Once tickets are allocated following the ballot, successful applicants will be required to fill in a form asking about dietary requirements and then pay into the TMS accounts. This information is summarised below:

TMS Centenary Dinner

Date and Time: 23rd February 2019, 7:30PM
Venue: Trinity Great Hall
Cost: £20 for current members
Dress Code: Black tie preferred
Menu: See below

This is a members-only event; if you are not already a member, you can join the TMS for life for only £2.50 at any of our events.

Reminder: Tickets are to be allocated via a ballot, *not* on a first-come first-served basis. Applications will close at 1PM on Friday 8th February. Successful applicants will receive a confirmation email on Friday afternoon.

Remember to check out our Centenary website at http://tms100.uk/ for further updates.

This should be a hugely exciting celebration, so good luck to all applicants!

Are we living in the matrix? – Professor David Tong (DAMTP)

Monday 4 February, 8:30PM
Are we living in the matrix?
Professor David Tong (DAMTP)
Here is an interesting fact: no one knows how to write down a discretised version of the laws of physics in a manner that allows them to be simulated on a computer. The obstacle is known as the Nielsen-Ninomiya theorem. I will describe this result and some attempts to circumvent it.

Solitons: An Introduction – 
Dr Anthony Ashton (DAMTP)

Monday 28 January, 8:30PM
Solitons: An Introduction
Dr Anthony Ashton (DAMTP)
Solitons are a very special type of solution to some nonlinear, dispersive PDEs. I will discuss some of the history of solitons, as well as some of their remarkable properties. The talk should take us from canal boats to pseudospherical surfaces, with some mathematics in between.

Please find the TMS Lent 2019 Termcard here – many exciting events planned for this term! That includes our TMS Centenary Dinner and Symposium, as well as numerous excellent speakers.

We hope to see lots of you attending. The next talk is next Monday, given by Dr Anthony Ashton.

Call My Bluff

It’s our final event of the term – the annual TMS tradition of Call My Bluff! A prime time for a poem:

of obscure math
terms; Will the other
team realise which are
true amongst the wrong ones?

TMS Call My Bluff
Date and Location: Monday 26th November, 8.30pm, Winstanley Lecture Theatre

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.

We have two impressive teams for an exciting showdown.

Rolls, Squares and Hexagons: pattern formation through instabilities – Prof. Michael Proctor (DAMTP)

Rolls, Squares and Hexagons: pattern formation through instabilities
Prof. Michael Proctor (DAMTP)
Date and location: Monday 19 November, 8:30pm, Winstanley Lecture Theatre

It is an experimental fact that when an extended system in a simple amorphous state becomes unstable, the new realised state is typically one exhibiting a pattern. It can be shown even for very complicated physical systems that the dynamical processes near the point in parameter space where stability is lost can be represented by a small number of ordinary differential equations. The form of these equations, and the interactions of any possible patterns that can result from the instability, is strongly influenced, and in many cases determined, by the symmetries of the system being studied. One the symmetry group is known, the different patterns can be identified with different representations of the group. I will discuss a number of examples of varying complexity.

Approximation on the Real Line – Prof. Arieh Iserles (DAMTP)

Our next talk will be given by Dr. Arieh Iserles (DAMTP).
Approximation on the Real Line
Dr. Arieh Iserles (DAMTP)


Date and location: Monday 12 November, 8:30pm, Winstanley Lecture Theatre

The purpose of the exercise is simple, to design an orthogonal basis in the space of square-integrable functions on the real line such that the linear map taking the basis to its derivatives is skew symmetric. Such bases possess numerous advantages in the computation of ODEs and PDEs. In this talk, based on a joint work with Marcus Webb, I will completely characterise all such orthogonal systems using Fourier analysis and the theory of orthogonal polynomials. The extension of this work to complex-valued skew-Hermitian `differentiation matrices’ is trivial but it leads to a beautiful outcome, an orthogonal system of rational functions designed (in a different context) almost a century ago by Malmquist and Takenaka and which exhibits some truly miraculous properties.

Stein’s Paradox – Prof. Richard Samworth (Statslab)

Our next talk will be given by Prof. Richard Samworth.

Stein’s Paradox
Prof. Richard Samworth (Statslab)

Date and location: Monday 29 October, 8:30pm, Winstanley Lecture Theatre

Stein’s paradox is one of the most striking results in Statistics. Although it appears to be a toy problem in mathematical statistics, it turns out to have profound implications for the analysis of modern, high-dimensional data. I will describe both the result and some of its consequences.

Film Night – Travelling Salesman

Important update – Professor Samworth’s talk has been rescheduled to the week after (29 Oct).

This Monday (22 Oct), we will be hosting our Film Night instead. The film will be ‘Travelling Salesman’ – brief description in a haiku.

Exciting thriller

What might it mean if you solve

P equals NP?

Date and Location: Monday 22 Oct, 8:30pm.Winstanley Lecture Theatre.

There will be some snacks (but no alcohol). We hope to see lots of you there.
