We have the pleasure to host a guest talk by department celebrity Ian Stewart, who will be presenting material from his new book, "Professor Stewart's Hoard of Mathematical Treasures". Make sure you take a look at the latest copy of our magazine, The Mathemagician: some excerpts of his latest book are included. After the talk, everyone is invited to the Staff Common Room for some food and drink. Many people from the mathematics department will be there, from undergraduates to lecturers! This is the first Discussion Group of the year, and as such it is an exceptional opportunity to hear about interesting mathematics. The regular Discussion Groups will be resuming on Week 4, so if you're starving for more interesting mathematics, don't fret! | ||

The Integrating Factor is our first major social of the year - and it's going to be big. The union is still a state so we'll be holding it in the department. Expect music, expect drinks and snacks, and, above all, expect epic banter! This is definitely not one to miss, whether; you want to meet people on the course, extend fresher's fortnight or simply take advantage of our massive socials budget! | ||

Discussion Groups, the WMS's regular informal talks about awesome maths, are kicking off this Monday with a look at one of the most baffling and most important unsolved problems in the whole of mathematics: the Riemann Hypothesis. The story starts about 200 years ago when Gauss, then a bored 15 year old, started counting the prime numbers in regular intervals and noticed that despite the fact that they seemed to pop up randomly among the other integers, they grew at a more or less regular rate. His conjecture came to be known as the "Prime Number Theorem" and attracted many mathematicians, to no avail, until Gauss' own student, Bernhardt Riemann, published, in 1859, a paper that provided a brilliant new way of looking at the problem and, in doing so, changed mathematics forever. One phrase of that paper, in particular, mentioned a certain conjecture involving the location of the roots of a certain function. Riemann deemed this to be of some interest but gave up looking for a rigorous proof after some "fleeting futile attempts". This was the Riemann Hypothesis. Fast forward 150 years later, although Riemann's ideas have eventually led to a proof of the Prime Number Theorem and an analogue of the Riemann hypothesis motivated much of the developments in modern algebraic geometry, which culminated in Deligne's proof of the Weil conjectures in 1973. However, Riemann's original conjecture remains open and as mysterious as ever. The talk will, as usual, be entirely informal, with emphasis on the interesting ideas rather than the technicalities and hence suitable for anyone from first-years to seasoned number theorists. So, if you've ever wondered what the Riemann Hypothesis was all about, if the primes really are that random, how to win a million dollars or just wanted to learn something interesting, come to MS.04 this Monday at 7:30pm, followed by the traditional post-DG trip to the pub. | ||

When we take a moment to consider mathematics and its distinct areas of study, we often classify it into two groups: continuous and discrete. The focus of this talk lies in an area formed by the union of combinatorics, which lies at the heart of discrete mathematics, and topology, which is commonly described as the study of continuity. Whilst the general area of combinatorial topology gave way to the more versatile algebraic topology in the early 1940's, there remain problems of a topological nature which can be more readily stated and proven in combinatorial terms. In this Discussion Group, Owen Daniel will first state and prove Sperner's Lemma, a purely combinatorial result, which will then be shown to be a surprisingly versatile tool culminating in a proof of the Brouwer Fixed Point Theorem, a classic problem of algebraic topology. So come along on Thursday to be guided through a meandering stream of mathematics: the pace will be gentle, and as such is suitable for all maths students. It is also an excellent example of what is suitable for a second year essay, as much of the talk is based on Owen's essay, available here. After the talk, as usual, we triangulate our way to the pub! | ||
