Power and Plenty - Trade, War, and the World Economy in the Second Millennium

In the grand tradition of the scholar-adventurer, acclaimed author Richard Cohen takes us around the world to illuminate our relationship with the star that gives us life. Drawing on more than seven years of research, he reports from locations in eighteen different countries. As he soon discovers, the Sun is present everywhere—in mythology, language, religion, politics, sciences, art, literature, and medicine, even in the ocean’s depths. For some ancient worshippers, our star was a man abandoned by his spouse because his brightness made her weary. The early Christians appropriated the Sun’s imagery, with the cross becoming an emblem of the star and its rays, and the halo a variation of that. Einstein helped replicate the Sun’s power to create the atomic bomb, while Richard Wagner had Tristan inveigh against daylight as the enemy of romantic love. In this splendidly illustrated volume packed with captivating facts, extraordinary myths, and surprising anecdotes, Cohen not only explains the star that so inspires us, but shows how multifacted our relationship with it has been—and continues to be.

Clear, insightful, and nondogmatic, this book gives us a new appreciation for one of our most ubiquitous institutions.

Astronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces readers to fundamental concepts and cutting-edge advances in modern astronomy.

The age of our universe poses a deceptively simple question, and its answer carries profound implications for science, religion, and philosophy. David Weintraub traces the centuries-old quest by astronomers to fathom the secrets of the nighttime sky. Describing the achievements of the visionaries whose discoveries collectively unveiled a fundamental mystery, he shows how many independent lines of inquiry and much painstakingly gathered evidence, when fitted together like pieces in a cosmic puzzle, led to the long-sought answer. Astronomers don't believe the universe is 13.7 billion years old--they know it. You will too after reading this book. By focusing on one of the most crucial questions about the universe and challenging readers to understand the answer, Weintraub familiarizes readers with the ideas and phenomena at the heart of modern astronomy, including red giants and white dwarfs, cepheid variable stars and supernovae, clusters of galaxies, gravitational lensing, dark matter, dark energy and the accelerating universe--and much more. Offering a unique historical approach to astronomy, How Old Is the Universe? sheds light on the inner workings of scientific inquiry and reveals how astronomers grapple with deep questions about the physical nature of our universe.
