Keith Mansfield tells us how being able to do maths turns you into a superhero, helps you work out why we haven't yet been contacted by aliens, and remembers his favourite mathematical moment.

Nira Chamberlain tells us how solving difficult maths problems can be like fighting an invisible boxer.

Vicky explains how maths is an adventure that's really worth having.

Carola tells us about her work in the field of image analysis, her favourite mathematical moments, and why creativity is so important in maths.

Mathematician Katie Steckles tells us about her favourite mathematical moments and why being creative is essential in maths.
