**22nd February**#### Computing and Maths - the Language of Numbers

Daniel Norman- For our opening lecture, we are pleased to welcome a local S6 school pupil to give us a young person's views on the importance of studying STEM subjects, which he has been investigating this year for his Baccalaureate project. Daniel will discuss some maths problems and their solutions as well as applications in the world of computers. He will also talk about some different maths concepts and computer solutions both simple and more advanced and show the computing solutions

**8th March**#### How to win at sports using maths

Dr Adrian Worton- Until recently, most cases of maths in sport were either relatively simple (such as designing point-scoring systems) or using maths to explain how certain sporting techniques worked (such as the Fosbury flop). After the high-profile success of 'Moneyball' strategies in baseball, using mathematics to influence on-field tactics has rapidly spread across the sporting world. This talk will look at some of the latest methods that are being used, and discuss where the industry of sporting analytics can go next. For example, can we come up with a formula that will help Scotland win the World Cup (almost certainly not).

A recording of this lecture can be viewed on Dr Worton's personal website at The Game is A Foot.

**22nd March**#### Life in Data - Data literacy and social change

Dr Eddy Borges Rey- The Open Data Charter was intended to facilitate citizens' access to information, but citizens have not made enough use of open data to deem the initiative a success. Some argue that this is due to a general lack of data literacy - the ability to read and articulate data in a meaningful way. With this in mind, this lecture will shed light on what data literacy is, why it matters, the current state of data literacy in Scotland, and how can it be fostered.

**5th April**#### The Golden Ratio

Prof Rachel Norman- The golden ratio is a special number approximately equal to 1.618 which appears many times in geometry, art, nature and other areas. In this talk I will explain where it comes from, look at where it appears in the real world, whether it is the most irrational number and how it relates to witchcraft.

**19th April**#### Sunrise, Sunset

Donald Smith- We all have a general understanding of how and why daylight hours vary with the seasons, but it is perhaps not as simple as we think. For example, did you know that the evenings start getting lighter in December before we reach the shortest day? We shall try to explain this and other phenomena by looking at the mathematics of planetary motion and consider how the sun's position in the sky really varies throughout the year.

**3rd May**#### Triangular Numbers - from Pythagoras to the Twelve Days of Christmas

Prof Helen Ross and Donald Smith- The numbers 1, 3, 6, 10, 15 etc are called triangular numbers. Can you see why? They have generated much interest among mathematicians since the days of the Ancient Greeks, and we shall follow the progress and development of this early knowledge across Europe, to the Irish monk Dicuil in the 9th century and the German mathematician Carl Friedrich Gauss in the late 18th century. Triangular numbers crop up in many simple problems and we shall look at a few of these. We are sure you can see their relevance to the 12 days of Christmas! And if we can have triangular and square numbers, why not pentagonal numbers as well?!

**17th May**#### Staying Secure - What should you do and why?

Dr David Cairns and Ken Reid- We are frequently told to stay secure whilst interacting in our increasingly connected world. This talk will discuss some of the core means by which we can try to maintain a secure presence online and explain the reasons behind the guidelines. We will demonstrate what happens when these guidelines are not followed and how good practice can prevent intrusion.
