No scientific quest is as compelling as the search for the key to understand the universe—the elusive unified “Theory of Everything”—a theory so concise it could fit on a T-shirt. Lively and thought-provoking, Universe on a T-Shirt tells the fascinating story of the search for the Holy Grail of physics. Dan Falk places this intriguing story in its historical context, tracing the quest from ancient Greece to the breakthroughs of Newton, Maxwell, and Einstein, to the excitement over string theory and today’s efforts to merge quantum theory with general relativity. With as much emphasis on history as on science, Falk’s accessible approach is ideal for anyone intrigued by the advances in modern physics but still wondering what theoretical physicists are searching for, and why. Today’s physicists use sophisticated methods, but their goal—the search for simplicity—has not changed since the time of the ancient Greeks. Universe on a T-Shirt is filled with quirky personalities, brilliant minds, and bold ideas—high science and high drama. An admirably concise and comprehensive overview of cosmology . . . [that] offers intriguing insights into the philosophic and personal outlooks motivating the scientists involved, from the ancient Greeks through Newton and Einstein . . . [and] Stephen Hawking and Ed Witten.”—Booklist

How do you picture identity? What happens when you ask individuals to make visual representations of their own identities, influences, and relationships? Drawing upon an array of disciplines from neuroscience to philosophy, and art to social theory, David Gauntlett explores the ways in which researchers can embrace people's everyday creativity in order to understand social experience. Seeking an alternative to traditional interviews and focus groups, he outlines studies in which people have been asked to make visual things – such as video, collage, and drawing – and then interpret them. This leads to an innovative project in which Gauntlett asked people to build metaphorical models of their identities in Lego. This creative reflective method provides insights into how individuals present themselves, understand their own life story, and connect with the social world. Creative Explorations is a lively and original discussion of identities, media influences, and creativity, which will be of interest to both students and academics.

If God does not exist, then what does? Is there good and evil, and should we care? How do we know what’s true anyway? And can we make any sense of this universe, or our own lives? Sense and Goodness answers all these questions in lavish detail, without complex jargon. A complete worldview is presented and defended, covering every subject from knowledge to art, from metaphysics to morality, from theology to politics. Topics include free will, the nature of the universe, the meaning of life, and much more, arguing from scientific evidence that there is only a physical, natural world without gods or spirits, but that we can still live a life of love, meaning, and joy.

The twentieth century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark book, John Gribbin—one of the best-known science writers of the past thirty years—presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified “Theory of Everything” that combines these ideas into one mathematical package, a single equation that could be printed on a T-shirt, containing the answer to life, the Universe, and everything. With his inimitable mixture of science, history, and biography, Gribbin shows how—despite skepticism among many physicists—these two great theories are very compatible, and point to a deep truth about the nature of our existence. The answer lies, intriguingly, with the age of the universe: 13.8 billion years.

The enigma of time has captivated journalist Dan Falk, who sets off on a journey In Search of Time. The quest takes him from the ancient observatories of stone-age Ireland to the atomic clocks of the U.S. Naval Observatory; from the layers of geological 'deep time' in an Arizona canyon to Albert Einstein's apartment in Switzerland. In the process, we meet great minds from the past and hear from today's most profound thinkers: Roger Penrose, Paul Davies, Julian Barbour, David Deutsch, Lee Smolin, and many more. Falk speaks with anthropologists and historians about our deep desire to track time's cycles, asks psychologists and neuroscientists about the mysteries of memory, and quizzes physicists about the beginning and end of time - not to mention the latest theories about time travel and the paradoxes it seems to entail.

"Steven A. Cohen is a Wall Street legend. Born into a middle class family in a decidedly upper class suburb on Long Island, he was unpopular in high school and unlucky with girls. Then he went off to Wharton, and in 1992 launched the hedge fund SAC Capital, which grew into a $15 billion empire. He cultivated an air of mystery and reclusiveness -- at one point, owned the copyright to almost every picture taken of him -- and also of extreme excess, building a 35,000 square foot house in Greenwich, flying to work by helicopter, and amassing one of the largest private art collections in the world. But on Wall Street, he was revered as a genius: one of the greatest traders who ever lived. That public image was shattered when SAC Capital became the target of a sprawling, seven-year criminal and SEC investigation, the largest in Wall Street history, led by an undermanned but determined group of government agents, prosecutors, and investigators. Experts in finding and using "black edge" (inside information), SAC Capital was ultimately fined nearly $2 billion -- the largest penalty in history -- and shut down. But as Sheelah Kolhatkar shows, Steven Cohen was never actually put out of business. He was allowed to keep trading his own money (in 2015, he made $350 million), and can start a new hedge fund in only a few years. Though eight SAC employees were convicted or pleaded guilty to insider trading, Cohen himself walked away a free man. Black Edge is a riveting, true-life thriller that raises an urgent and troubling question: Are Wall Street titans like Steven Cohen above the law?"--
