Nothing annoys Eugenia Cheng more than the suggestion that there is no creativity in mathematics. Doing mathematics is not about being a human calculator, she says. She doesn't spend her time multiplying big numbers in her head. She sits in hotel bars drawing (mainly arrows) with a fine quill pen, thinking about how ideas from different areas of mathematics relate to one another and hoping to reveal a unifying, underlying logic to the whole of mathematics. Her area of research, Category Theory, makes algebra seem superficial. And if that makes your head hurt a little, don't worry. Feeling confused is an essential part of doing mathematics. 'You can't make progress without it' Eugenia says. Jim asks Eugenia what drove her to such a high level of abstraction and learns more about her mission to rid the world of maths phobia, by baking.
