This book is based on an in-depth filmed conversation between Howard Burton and Nima Arkani-Hamed, faculty member at the renowned Institute for Advanced Study in Princeton. Nima Arkani-Hamed is one of today''s leading particle physicists. In this extensive Ideas Roadshow conversation Nima discusses how we discover the laws of nature, the "scientific method", the relation between theory and experiment and how we can push our understanding well beyond where experiments can currently reach. With his unbridled enthusiasm and engaging eloquence, Nima takes us inside the world of a working theoretical physicist, sharing his frustration at some of the ways that physics is communicated to the general public while revealing how he and his colleagues hope to be steered towards the truth without experiment to guide them.This carefully-edited book includes an introduction, Beyond Nymphs, Dryads and Leprechauns, and questions for discussion at the end of each chapter:I.
