    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.

    But it will tell you what a lot of people think about pigs, robots, the tooth fairy, and more serious topics like God and right and wrong and what’s worth living for. You’ll meet a lot of people in this book, real ones, who have tried all kinds of lifestyles with all kinds of results.

    His father, musician Vincenzio Galilei said, “Truth is not found behind a man’s reputation. Truth appears only when the answers to questions are searched out by a free mind. This is not the easy path in life but it is the most rewarding.” Galileo challenged divine law and the physics of Aristotle, and questioned everything in search of truths. And it was through this quest for truth that he was able to establish a structure for modern science.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    He introduces the young reader to people like Von Helmont, Boyle, Stahl, Priestly, Cavendish, Lavoisier, and many others, all incredibly diverse in personality and approach, who have laid the groundwork for a search that is still unfolding to this day.

    Brendan, award-winning adventure writer Tim Severin painstakingly researched and built a boat identical to the leather curragh that carried Brendan on his epic voyage. He found a centuries-old, family-run tannery to prepare the ox hides in the medieval way; he undertook an exhaustive search for skilled harness makers (the only people who would know how to stitch the three-quarter-inch-thick hides together); he located one of the last pieces of Irish-grown timber tall enough to make the mainmast. But his courage and resourcefulness were truly tested on the open seas, including one heart-pounding episode when he and his crew repaired a dangerous tear in the leather hull by hanging over the side--their heads sometimes submerged under the freezing waves--to restitch the leather. A modern classic in the tradition of Kon-Tiki, The Brendan Voyage seamlessly blends high adventure and historical relevance. It has been translated into twenty-seven languages since its original publication in 1978.With a new Introduction by Malachy McCourt, author of A Monk Swimming

    What was it that enabled him to stand so steadfastly when all those around him seemed to turn back in fear? What was it that enabled him to inspire whole nations to endure the unendurable and to achieve the unachievable when all those around him had already surrendered all hope? This remarkable new study of Churchill's leadership skill answers these questions and more. The result is an account that is as inspiring today as it was more than half a century ago when the great man' shadow fell large across the world stage. According to Henry Kissinger, Our age finds it difficult to come to grips with Churchill. The political leaders with whom we are familiar generally aspire to be superstars rather than heroes. The distinction is crucial. Superstars strive for approbation; heroes walk alone. Superstars crave consensus; heroes define themselves by the...future they see it as their risk to bring about. Superstars seek success in a technique for eliciting support; heroes pursue success as the outgrowth of their inner values. Winston Churchill was a hero.

    David Peat explains the development and meaning of this Superstring Theory in a thoroughly readable, dramatic manner accessible to lay readers with no knowledge of mathematics. The consequences of the Superstring Theory are nothing less than astonishing.
