**Data Is Information Is Power: Games With Experiments And Probability.**

** Age: 7+**

It's well known that information is power, but how do we gain information about the world around us in order to make decisions? One answer lies in collecting data about the world, and then using Statistics, Mathematics and Probability to turn these data into information from which we can learn. These ideas are at the heart of science, and are used to help make decisions on the effectiveness of new drugs and the design of cars and aeroplanes, as well as many other decisions. We demonstrate how we can learn from this combination of data and probability using the well-known scientific equipment Battleships, Guess Who, and other games.

**Diffusion Of The Dead**

Knowing how long we have before we interact with a zombie could mean the difference between life, death and zombification. Here, we apply the same mathematical models to zombies that you would use to describe flu, or measles. We use this model to derive human-zombie interaction times and use these to develop strategies which allow the human race to survive their impending doom. A talk by Thomas Woolley.

The notion of minimising effort underlies much of the physical world (as well as the mental one ...). As circumstances alter, choices of response are often directed from the mathematical point of view by only a small number of geometric forms that are called elementary catastrophes - although not necessarily catastrophic. We will look at some examples from rainbows and caustics to climate change and politics. A talk by David Chillingworth.

**Gravitational Waves: A New Window To The Universe**

** All ages**

** Type: Talk**

In this talk, Emma Osborne will take you on a journey through the gravitational wave universe. Learn about what gravitational waves are, how they are made, and how scientists detect them. Discover the monster gravitational wave machines that live in space, and how they can be used to solve the mysteries of the universe, as we embark on the era of multi-messenger astronomy.

The most ancient and basic mathematical activity is counting, using integers to count finite sets, such as a flock of sheep. But how do we count infinite sets, such as the sets of all integers, or of real numbers? In the 19th century Cantor showed that there are infinite numbers we can use for this. They help us to solve problems such as what to do when an unbooked guest arrives at a hotel where all the rooms are occupied, and they also tell us that some infinite sets are more infinite than others. A talk by Gareth Jones.

**Making Sure You Count: An Introduction To The Census And Demography**

** All ages**

How do we know how many people there are in the country? Where should we build the next schools or parks? How happy are people in England, and how do we measure happiness? All these questions and more can be explored through demography, the study of people! And tools like the Census aim to help us to do so. In this stall, we want to give visitors a better understanding of how the Census, the Office for National Statistics, and demography help us understand ourselves.

Geometry, invented by the ancients to describe the physical world in which we live, is still very relevant today to describe our increasingly complex world. The talk will trace the development of geometric ideas from Pythagoras and Archimedes to the development of topology and its applications to modern problems in data analysis. Far from being old fashioned, the geometric point of view provides very powerful insights into the structure of our world and provides methods to understand complicated problems in data science with some really important applications. A talk by Jacek Brodzki.

**Particle Physics In Mixed Reality**

** All ages**

This exhibit will allow you to explore fundamental theories of Nature that describe particles, black holes and the very beginning of the Universe. If you have ever wondered what the smallest type of particle is, what happened at the Big Bang or what would happen if you fell into a black hole, then this exhibit will help you answer these questions.

**The Cosmic Gold Factory**

** All ages**

On the 17th of August 2017 astronomers struck gold. A faint signal shaking the two LIGO gravitational-wave detectors was followed by an intense flash of light caught by orbiting telescopes. We had witnessed the first merger of two neutron stars - objects so dense that their interior challenges our imagination. The observations confirmed the connection between neutron-star collisions and cosmic gamma-ray bursts and we learned that these events are cosmic gold factories. This interactive display introduces neutron stars and gravitational waves and explains why this discovery was so exciting.

Using mathematics to improve decision-making in the real-world: from airline ticket pricing, to lifeboat maintenance, to dealing with disease epidemics. Whether its an individual, a small charity, or a big business, the decisions we make can have a huge impact, and in this we talk we will describe how mathematics can be used to ensure that these decisions are the best they can be. A talk by Christine Currie/ Ruth Walton.

**Thinking About Strange Shapes In Other Dimensions**

** All ages**

Growing up in our ordinary three-dimensional world has given us a fairly good intuition for what this type of space looks like. But what happens when this intuition isn’t enough? How can we think about spaces that don’t have the usual properties that we’re used to, and/or lie in higher dimensional spaces? This is an opportunity to think about different kinds of shape (topology) using short games and exercises including noughts and crosses on a torus (using paper/card/white boards).
