This app/book version of Hawking's famous laymen book is just an amazing piece of learning. This makes much more accessible and understandable the complex and awesome topics dealt by Hawking as he explains how our universe works. I am just in awe at how creative he is to produce one of a kind e-book like this. The pace, illustrations and connections of topics within the book are so helpful and so appropriate for the new generation used to tweets and small bites of information. You can flip over some topics when you have some time, learn some amazing fact, and come back later which no rush or worry about how fast you are progressing through the book. Hope other books on complex topics are translated to this format. And I love the updates of the latest science since the publication of the original book. We have learned so much in the last decade that I agree with Hawking, it is an honour to live in this times.

Master of the Universe... One scientist's courageous voyage to the frontiers of the Cosmos

This book marries a child's wonder to a genius's intellect. We journey into Hawking's universe, while marvelling at his mind

He can explain the complexities of cosmological physics with an engaging combination of clarity and wit... His is a brain of extraordinary power

To follow such a fine mind as it exposes such great problems is an exciting experience

One of the most brilliant scientific minds since Einstein

Renowned for his innovative conflation of pure physics and computation, Lloyd is well positioned to hack his way into space-time and come back with answers

What an astonishing book! Lloyd is at the forefront of a revolution

A marvelously capacious book that will attract serious readers everywhere

Any reader who has avoided science for fear of being overwhelmed will find a friendly guide in Potter ... This clear and smoothly written look at the mind-boggling history of everything is both informative and provocative

This Portable History of the Universe is awe-inspiring in its reach. It ranges easily over millions of miles and takes in billions of centuries at a stroke, yet at the same time it's somehow intimate and conversational in its manner. The engaging medium is the message, perhaps: to contemplate the universe, suggests Potter, is "to find ourselves at two poles at the same time: we are uniquely special and we are insignificant". Playing both poles against the middle with extraordinary aplomb, his book opens up to us the vastness of the cosmos

Less folksy and biographical than Bill Bryson, less zany than a Bluffer's Guide. But many a bang for your buck, washed down with quotations from the greats ... Potter has an engaging style

With marvellous clarity, compassion, erudition, humour and open-mindedness, Potter blasts us through the vast vacuum of space
