"Much journalistic coverage fails to appreciate that the science is fascinating enough as it is without exaggeration and distortion...It is therefore refreshing to have this biography that tells both the human story of his life, and of the development of his scientific contributions in their historical context without hype...this book is engaging and informative...I recommend [it] to anyone who is curious about Stephen Hawking and his contributions to science." -- Nature Physics, June 4, 2008
