## Science & Engineering

Maggie Aderin-Pocock is a space scientist developing telescopes and instruments for satellites. Her passion for communicating her science has also led her back into the classroom, into filming documentaries and appearing on prime time TV with Jeremy Paxman.

What's it like being a research mathematician and figurehead of Europe's representative body for mathematics? Find out in our interview with Marta Sanz-Solé.

If you're interested in maths then Marcus du Sautoy does not really need an introduction: he is well known for his TV and radio appearances and popular maths books. And he's also written for *Plus* in the past. In this interview he chats about his work as a mathematician and maths populariser.

Heather MacKinlay's work as an engineer has taken her from the civility of Surrey to the wild west of Australian mining towns and multibillion pound projects in the Algerian desert. And along the way she has also become a successful painter. Heather tells Plus that engineering and painting are just different ways of looking at the world, and how her work as a cost engineer is all about understanding the big picture.

Plus bumped into an old friend at the International Congress of Mathematicians this year: Keith Mansfield is the author of the Johnny Mackintosh series and commissioning editor for mathematics at Oxford University Press at the same time. In this interview he tells us how his he's built a career around his two talents, writing and maths.

Why do people become mathematicians? What's it like being one and what are the perks of a job in academia? We talk to young mathematicians at the International Congress of Mathematicians, as well as to established research mathematician Larry Guth to find out.

**Gavin Harper**, a mathematician and statistician, has put himself right at its centre. He works for Oxford Nanopore Technologies, a company which is developing new technology for analysing molecules and sequencing DNA. With 75 employees from 18 different countries and all sorts of scientific backgrounds, Gavin's work environment is nothing like the solitary paper-and-pencil affair traditionally associated with mathematics.

**Andy Green**, Royal Air force pilot and Oxford maths graduate, is gearing up to break his own land speed record in Bloodhound SSC, a supersonic car designed to reach speeds of up to 1000mph. He tells

*Plus*about the challenges — and the maths — behind this engineering adventure.
