Stephen Hawking's ability to make science understandable and compelling to a lay audience was established with the publication of his first book, A Brief History of Time, which has sold nearly 10 million copies in 40 languages. Hawking has authored or participated in the creation of numerous other popular science books, including The Universe in a Nutshell, A Briefer History of Time, On the Shoulders of Giants, The Illustrated On the Shoulders of Giants, and George's Secret Key to the Universe.

(Stephen William Hawking; Oxford, Reino Unido, 8 de Enero de 1942 - Cambridge, 14 de marzo de 2018) Físico teórico británico. A pesar de sus discapacidades físicas y de las progresivas limitaciones impuestas por la enfermedad degenerativa que padecía, Stephen William Hawking es probablemente el físico más conocido entre el gran público desde los tiempos de Einstein. Luchador y triunfador, a lo largo de toda su vida logró sortear la inmensidad de impedimentos que le planteó el mal de Lou Gehrig, una esclerosis lateral amiotrófica que le aquejaba desde que tenía 20 años. Hawking es, sin duda, un ejemplo particular de vitalidad y resistencia frente al infortunio del destino.

Fue miembro de la Real Sociedad de Londres, de la Academia Pontificia de las Ciencias y de la Academia Nacional de Ciencias de Estados Unidos. Fue titular de la Cátedra Lucasiana de Matemáticas (Lucasian Chair of Mathematics) de la Universidad de Cambridge desde 1979 hasta su jubilación en 2009. Entre las numerosas distinciones que le han sido concedidas, Hawking ha sido honrado con doce doctorados honoris causa y ha sido galardonado con la Orden del Imperio Británico (grado CBE) en 1982, el Premio Príncipe de Asturias de la Concordia en 1989, la Medalla Copley en 2006, la Medalla de la Libertad en 2009 y el Premio Fundación BBVA Fronteras del Conocimiento en 2015.

Alcanzó éxitos de ventas con sus trabajos divulgativos sobre Ciencia, en los que discute sobre sus propias teorías y la cosmología en general; estos incluyen A Brief History of Time, que estuvo en la lista de best-sellers del The Sunday Times británico durante 237 semanas.

La Editorial Alvi Books le dedicó, como tributo y reconocimiento, este espacio en Amazon en 2016.

Lucy Hawking, Stephen's daughter, is a journalist and novelist. She is the author of the adult novels Jaded and Run for Your Life. She lives in London with her son.

Bill Bryson was born in Des Moines, Iowa, in 1951. Settled in England for many years, he moved to America with his wife and four children for a few years ,but has since returned to live in the UK. His bestselling travel books include The Lost Continent, Notes From a Small Island, A Walk in the Woods and Down Under. His acclaimed work of popular science, A Short History of Nearly Everything, won the Aventis Prize and the Descartes Prize, and was the biggest selling non-fiction book of the decade in the UK.

Christophe Galfard would be very happy if everyone understood the universe as it is known today. He believes the world and its inhabitants would benefit greatly from this, and that kind of matters to him. So, for this to happen, he began writing books. For children, first. He started with "George's Secret Key to the Universe", which he co-wrote with Professor Stephen Hawking and his daughter, Lucy.

If you wonder how on Earth did he manage to write a book with Stephen Hawking, well, Christophe actually holds a Ph.D. in Theoretical Physics from Cambridge University (UK), and his supervisor was Stephen Hawking. Together, they worked on the so-called Black Hole Information Paradox (and the origins of our universe).

Christophe has spent years giving popular science talks about our universe, throughout the world. Having met many, he now believes that not only kids but adults too, can understand it all. "The Universe in Your Hand - A Journey Through Space, Time and Beyond" is a pop-science book that brings you to the cutting edge of today's knowledge without needing any scientific background whatsoever. He hopes you'll enjoy the trip, and that it will make you feel good. Very good, even.
