Who co-authored 'A Briefer History of Time' with Stephen Hawking?

Who co-authored A Briefer History of Time with Stephen Hawking? The answer is Leonard Mlodinow.

Mlodinow, an American theoretical physicist and author, collaborated with Hawking on this popular-science book, first published in 2005. It was designed as an update and more accessible rewrite of Hawking's 1988 bestseller A Brief History of Time.

The book revisits subjects including the Big Bang, black holes, quantum mechanics and string theory. Its shorter, more visual presentation reflects the authors' aim to explain difficult modern physics to a broad readership without requiring advanced mathematics.

Readers sometimes confuse this title with A Brief History of Time, which was written by Hawking alone. Mlodinow later co-authored another major cosmology book with Hawking, The Grand Design, published in 2010.
