This book comprises of a collection of conversations with Professor Lewis Wolpert, in which scientists from all different fields, ranging from cosmology to psychology, give insights into their lives in the profession. In a series of non-technical accounts, science is revealed as human enterprise with incidents and personal characteristics, such as imagination and style, which have influenced the route to discovery. The conversations are based on a BBC Radio series. The stories told and the different persectives they offer may be of interest to professional scientists and general readers.
