Cédric Villani won the prestigious Fields Medal for his work in 2010. He wrote a book about his experience called Birth of a Theorem: A Mathematical Adventure. It is a book about where ideas come from. There is something spider like about Villani, and I say that not just because of the pins he is famous for always wearing. He knows how to catch ideas, and he wants to teach us how as well. We also talk with Maria Popova about another great Science book: The art of Scientific Investigation. I found this book thanks to the idea catching web that Maria Popova built: brainpickings.org.
