Mathematicians often say that being creative is hugely important in maths. But why? We asked mathematician Katie Steckles, who told us about her favourite mathematical moments and why imagination is everything.

Mathematical moments is a series of short interviews with mathematicians about their work and the role of creativity in maths. This is the first interview of the series — stay tuned for more! The video will also appear on our sister site Wild Maths, which encourages students to explore maths beyond the classroom and is designed to nurture mathematical creativity.
