Alan Turing and The Imitation Game
Dr Savi Maharaj and Donald Smith
- As a taster for the new season's lectures, here is a second chance to hear the popular talk we gave at the Macrobert cinema in December to tie in with the acclaimed film, The Imitation Game. The film is returning to the Macrobert in the last week in January for a limited number of screenings. Film details here.
- As well as solving the Enigma code, Alan Turing made remarkable contributions to Mathematics and is widely considered to have founded the field of Computing Science. In this lecture, we shall give an accessible introduction to some of Turing's great scientific achievements and have a look at the history of the Enigma machine and why it was so difficult to crack.

The life of Pi and other irrational things
Professor Rachel Norman
- In this talk we will look at some interesting and unusual numbers, what we use them for and where they came from. We will start with pi and look at how it has been calculated and used throughout history. Expect a torrid tale of death and irrationality.

Cmprsd Vw f nfrmtn Thry: A Compressed View of Information Theory
Dr John Woodward
- Information theory is a branch of probability that measures the abstract quantity of information. We will ask some of the following questions during the lecture. Is a picture really worth 1000 words? Does the Complete Works of Shakespeare contain more information in its original language or a translation? Why is tossing a coin the best way to make a decision? What is your best defence when interrogated about a crime you did commit (at least from an information theory point of view)? Finally, why is the original scientific paper outlining information theory still relevant? This talk will focus very much on concepts and understanding, with few mathematical formulae.

Ant hills, traffic jams and social segregation: modelling the world from the bottom up
Dr Savi Maharaj
- Today's powerful computers make it possible to study the world by simulating the actions of hundreds, thousands or millions of individuals whose interactions with each other produce emergent behaviour that we can see. This form of computational modelling, called agent-based modelling, has been used to study how ant hills are built, why birds fly in flocks, how traffic jams can be avoided, how segregated communities emerge in cities and many other diverse phenomena. This talk will present several examples of agent-based models and discuss what we can learn by modelling the world in this way.

Happy Birthday, Ada Lovelace: the story of computer programming
Professor Carron Shankland

Play it by numbers
Dr Darren Green
- Music is not just art; it is a science too. In fact, the Oxford English Dictionary defines "music" as "the art or science of combining vocal or instrumental sounds to produce beauty of form". Mathematical principles lie at the heart of these sounds and form, and can be found in all aspects of music, from the sounds themselves and how they are produced by us, the way in which sounds combine to give us pleasing chords, to the way in which we put sounds together to form scales, melodies, and whole musical works. This lecture will explore some of the simple beautiful maths that underlies music. For example, just why does a piano have 12 notes per octave, rather than some other number, and what was the "devil in music"?

What's all the fuss about Big Data?
- Over 90% of all the data created by mankind was generated in the last two years and the scope of what is recorded is vast. Every message we send, every item we buy, our physical location, the power we consume, the web pages we view and the searches we make are all recorded and, to some extent, analysed. We post our photographs online and tweet about our breakfasts. So many systems are producing data - from stock prices to where Andy Murray's serves land - and everything is recorded and sifted for that insight that gives someone an edge. This shift from a reliance on human knowledge to statistical analysis is changing everything from the way our team plays at the weekend to the way politicians choose their policies and it raises questions about privacy, discrimination and trust.
