4In 1905, a young Albert Einstein, while he worked in a humble patent office in the Swiss city of Bern, was developing his theory of relativity, a new concept of time. Inspired by these modest times, Alan Lightman imagines a fictional Einstein dreaming about many possible worlds, about many possible existences. Originally published in 1993, Los sueños de Einstein is considered a modern classic, helping bridge the light-year-size gap between science and literature.
