Bill Bryson brings wonder to science in refresh of hit book

In his hit 2003 pop science book, A Short History of Nearly Everything, writer Bill Bryson took readers on a journey from the birth of the universe to the inner workings of a cell, and had them laughing along the way. Over 20 years on, Bryson joins Piya Chattopadhyay to explain why he's now updating his seminal work to explore what’s changed, what hasn’t, and what still amazes him, even in times of existential dread.
