Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the Big Bang to black holes, via spiral galaxies and strong theory. To this day A Brief History of Time remains a staple of the scientific canon, and its succinct and clear language continues to introduce millions to the universe and its wonders.
In this paradigm-shifting health book, #1 New York Times bestselling co-author of The Whole30 and It Starts with Food reveals a powerful new program to help us feel happier, healthier, and less stressed. Fatigue. Burnout. Weight gain. Disease. Despite seemingly endless programs designed to help us lose weight and regain our health, readers are more overworked, overtired, and overweight than ever. In All in Good Time, Hartwig reveals the four keys of health - sleep, eat, move, connect - and explains how we can reconcile the needs of our ancient bodies with the demands and complications of modern life. Today, more than at any point in history before us, we are more disconnected from the natural world than ever. Our ancestors would have honoured the changing seasons, adjusting their sleep, eating, exercise, and socializing habits based on the light, weather, and available food options. They would have slept more in winter, traversed longer distances in summer. But we wake before the sun rises and go to bed long after it sets. We spend most of our day indoors, in artificial light conditions. We can eat tropical fruits from halfway around the world in the dead of winter. We exercise in climate controlled environments, doing the same routine year round. We connect virtually instead of emotionally and physically. We go, go, go, until we pass out, exhausted, at the end of the day, by the constant blue light of our phones. In other words, we are living in an endless summer, and it's killing us. All in Good Time provides a new, sustainable model for living more in sync with the natural rhythms of the universe. By making small but meaningful changes to each health key over the course of the year, readers will reclaim their health, regain their energy, and let go of excess weight.
When and how did the universe begin? Why are we here? Is the apparent 'grand design' of our universe evidence for a benevolent creator who set things in motion? Or does science offer another explanation? In The Grand Design, the most recent scientific thinking about the mysteries of the universe is presented in language marked by both brilliance and simplicity. Model dependent realism, the multiverse, the top-down theory of cosmology, and the unified M-theory - all are revealed here. This is the first major work in nearly a decade by one of the world's greatest thinkers. A succinct, startling and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform - and provoke - like no other.
