Like his mentor and colleague Stephen Hawking, Thomas Hertog has never shied away from being ambitious in theorizing about the universe. This sweeping book provides an accessible overview of both what we know about cosmology, and some audacious ideas for moving into the unknown. It is an introduction to Hawking's final theory, but also a glimpse into even grander theories yet to come.

Hawking and Hertog, with their "top-down cosmology", are pushing for nothing less than a new philosophy of physics... The concepts and arguments presented here are truly mind-stretching... The Origin of Time is immensely rewarding.

A fascinating insight into one of humankind's deepest quests, by one of its deepest minds.

Hertog's book is a fascinating tour of cosmology, the science of the Universe's origins

Stephen Hawking's final theory is lucidly explained in this splendidly accessible book. Author Thomas Hertog, one of Hawking's closest collaborators, gives us a vivid insight into Hawking as both a brilliant physicist and an astonishingly determined human being.

A beautifully written, thought-provoking account of both the physics and the personalities involved in Hawking's visionary struggle to comprehend the cosmos. Thomas Hertog has provided a fascinating insider view.

A must read

Why is our universe the way it is? How did everything begin? How might it end? Thomas Hertog probed these overwhelming questions in collaboration with Stephen Hawking - thereby achieving a privileged perspective into how, struggling against daunting physical odds, Hawking's imprisoned mind yielded astonishing insights even in his later years. This superbly written book offers insight into an extraordinary individual, the creative process generally, and the scope and limits of our current understanding of the cosmos.

A wonderful book about Stephen Hawking's biggest legacy (which no one outside of physics has heard of)... The origin of the universe, a feeling of cleverness, a possible fresh answer to the ancient metaphysical problem of our insignificance, and a new game - not bad for £20.

A remarkable collaboration

On the Origin of Time is a gentle polemic, selling a particular theory, but no less rich and fascinating for that.... It alternates between gnomic conversations over tea with Hertog's famous late mentor and deliciously mind-bending ideas, such as that time itself stops inside a black hole.

The nutrition revolution is well underway and Tim Spector is one of the visionaries leading the way. His writing is illuminating and so incredibly timely.

Will actually help you decide what to add to your next grocery shop... This is one of the clearest and most accessible short nutrition books I have read: refreshingly open-minded, deeply informative and free of faddish diet rules.

A well-researched and informative book ... Great to see academia catching up with the real world.

The book that needed to be written about the Lake District.
