This autobiography of C.S.Lewis’s early life, focusing on the spiritual crisis which was to determine the shape of his entire life, now repackaged and rebranded as a key title in the C.S. Lewis Signature Classics range. “In the Trinity Term of 1929 I gave in, and admitted that God was God…perhaps the most dejeced and reluctant convert in all England.” Thus C.S. Lewis describes memorably the crisis of his conversion in his famous autobiography. Lewis was for many years an atheist, and in Surprised by Joy he vividly describes the spiritual quest which eventually convinced him of the truth and reality of the Christian faith.

The bestselling author of Fermat’s Last Theorem and The Code Book tells the story of the brilliant minds that deciphered the mysteries of the Big Bang. A fascinating exploration of the ultimate question: how was our universe created? Albert Einstein once said: ‘The most incomprehensible thing about the universe is that it is comprehensible.’ Simon Singh believes geniuses like Einstein are not the only people able to grasp the physics that govern the universe. We all can. As well as explaining what the Big Bang theory actually is and why cosmologists believe it is an accurate de*ion of the origins of the universe, this book is also the fascinating story of the scientists who fought against the established idea of an eternal and unchanging universe. Simon Singh, renowned for making difficult ideas much less daunting than they first seem, is the perfect guide for this journey. Everybody has heard of the Big Bang Theory. But how many of us can actually claim to understand it? With characteristic clarity and a narrative peppered with anecdotes and personal histories of those who have struggled to understand creation, Simon Singh has written the story of the most important theory ever.
