With whom did Stephen Hawking co-author 'The Grand Design'?

Stephen Hawking co-authored The Grand Design with Leonard Mlodinow. Published in 2010 by Bantam Books, the popular-science work examines scientific ideas about the universe, including quantum mechanics, cosmology, M-theory and the possibility of a multiverse.

Mlodinow was an American theoretical physicist, mathematician and science writer. He had previously collaborated with Hawking on A Briefer History of Time, a 2005 update and simplification of Hawking’s earlier book A Brief History of Time. Their partnership combined Hawking’s authority as a cosmologist with Mlodinow’s experience explaining difficult scientific concepts for general readers.

The Grand Design became especially controversial because it argued that the laws of physics could explain the origin of the universe without requiring a creator. That argument is why readers sometimes remember the book through its debate about God rather than its authorship. The other names in the quiz are associated with Hawking or theoretical physics, but Leonard Mlodinow is the book’s sole co-author.
