Ian Stewart - Inspired by Math #14

I ask Dr. Stewart to share his inspiration and enthusiasm about mathematics. Where do the ideas and the inspiration for writing your books come from? Where does your love of math and passion for sharing it come from? Is there an early childhood experience that served as a catalyst? What is mathematics to you? What is your favorite branch of mathematics and why? Can you share a story or two about someone who read one of your books and had their attitude towards math change? What do you think it is that readers are hungry for that you're feeding? What is your next book? What advice would you give to a parent whose child was struggling with math?
