Editor's Note

Stephen Hawking and his mentee Thomas Hertog wrote a book after Hawking decided his best-seller was “written from the wrong perspective”. The Guardian’s science editor reads it ahead of its release.

In 2002 Thomas Hertog received an email summoning him to the office of his mentor Stephen Hawking. The young researcher rushed to Hawking’s room at Cambridge. “His eyes were radiant with excitement,” Hertog recalls.

Typing on the computer-controlled voice system that allowed the cosmologist to communicate, Hawking announced: “I have changed my mind. My book, A Brief History of Time, is written from the wrong perspective.”
