About the Authors

Vincent Knight

Vincent Knight is a Chair in the School of Mathematics at Cardiff University, where he works on game theory, applied mathematics, and open-source scientific software. His research spans the iterated prisoner’s dilemma, the modelling of emergency healthcare systems, and the reproducible practice of computational science. He is the author and maintainer of several open-source libraries, including Nashpy and the Axelrod-Python project. He wrote the book Python for Mathematics and, with Dr Geraint Palmer, Applied Mathematics with Open-Source Software: Operational Research Problems with Python and R (Routledge). More of his work can be found at vknight.org.

James Brown

The illustrations in this book are the work of James Brown. James is an artist, an award-winning filmmaker, and a game developer whose work is drawn to group interactions and systems: connection, trust, and the conditions under which people cooperate. He studied Intermedia at the Elam School of Fine Arts and spent several years as an independent game developer before turning to the games, simulations, and digital art that he now makes.

Much of that work lives at his wonderful site, nonzerosum.games, which he describes as an exploration of non-zero-sum games and of the idea that we are more than the sum of our parts. It is well worth a visit, and we are delighted that his art sits alongside the mathematics in these pages.
