Author: Stephen Hawking In his 1993 book “Black Holes and Baby Universes,” Stephen Hawking offers a collection that feels part memoir, part science lesson, and part invitation to wonder about questions that are still unresolved. Instead of building one long argument, the book moves through essays that connect Hawking’s personal life to the ideas that made him one of the most influential scientific thinkers of the modern era. A major theme of the collection is how a life can shape a mind.
