Light begins at Stonehenge, where crowds cheer a solstice sunrise. After sampling myths explaining First Light, the story moves on to early philosophers' queries, then through the centuries, from Buddhist temples to Biblical scripture, when light was the soul of the divine. Battling darkness and despair, Gothic architects crafted radiant cathedrals while Dante dreamed a "heaven of pure light." Later, following Leonardo's advice, Renaissance artists learned to capture light on canvas. During the Scientific Revolution, Galileo gathered light in his telescope, Descartes measured the rainbow, and Newton used prisms to solidify the science of optics. But even after Newton, light was an enigma. Particle or wave? Did it flow through an invisible "ether"? Through the age of Edison and into the age of lasers, Light reveals how light sparked new wonders--relativity, quantum electrodynamics, fiber optics, and more. Although lasers now perform everyday miracles, light retains its eternal allure. "For the rest of my life," Einstein said, "I will reflect on what light is." Light explores and celebrates such curiosity.

In Empire of Light, Sidney Perkowitz combines the expertise of a physicist with the vision of an art connoisseur and the skill of an accomplished writer to offer a unique view of the most fundamental feature of the universe: light. Empire of Light discusses the nature of light, how the eye sees, and how our understanding of these phenomena have emerged over the ages, including the role of light in the development of quantum physics. The author examines the making of electrical light and its integration into commerce, telecommunications, entertainment, medicine, warfare, and every other aspect of our daily lives. And he presents the role of light in the search for the beginning and the end of the universe, as astronomers with their instruments penetrate ever deeper into the sky. Visible light spans the spectrum between infrared and ultraviolet, but this book reaches across many other spectra as well--from the cave paintings at Lascaux to Mark Rothko's stark blocks of color in today's art museums, from Plato's speculation that the eye sends out rays to Ramon y Cajal's discovery that vision actually works in the opposite way, from Tycho Brahe's elegant antetelescope measurements of planet positions to the Hubble telescope's exquisite sensitivity to light from billions of light years away. What are the biological and neurological processes of perceiving visible light? How does a person typically scan a scene? Do you see red or blue the same way I do? What are our physiological reactions and emotional responses to light? Perkowitz explores these and many other fascinating questions, drawing together the experiences, achievements, and perspectives of a diverse cast of characters, including Galileo, Einstein, Newton, Van Gogh, and Edison. Empire of Light is written so that lay readers will readily grasp the scientific principles and science professionals will readily appreciate the human experience. It will impart new wonder to the daily experience of light in our world. Sidney Perkowitz is the Charles Howard Candler Professor of Physics at Emory University. His work has appeared in national publications such as The Sciences, The Washington Post, The Los Angeles Times, The American Prospect, and Technology Review.

A riveting account of one of the most remarkable episodes in American history. In his critically acclaimed history Freedom Summer, award- winning author Bruce Watson presents powerful testimony about a crucial episode in the American civil rights movement. During the sweltering summer of 1964, more than seven hundred American college students descended upon segregated, reactionary Mississippi to register black voters and educate black children. On the night of their arrival, the worst fears of a race-torn nation were realized when three young men disappeared, thought to have been murdered by the Ku Klux Klan. Taking readers into the heart of these remarkable months, Freedom Summer shines new light on a critical moment of nascent change in America. "Recreates the texture of that terrible yet rewarding summer with impressive verisimilitude." -Washington Post

Hair A Human History

A microhistory in the vein of Salt and Cod exploring the biological, evolutionary, and cultural history of one of the world's most fascinating fibers. Most people don't give a second thought to the stuff on their head, but hair has played a crucial role in in fashion, the arts, sports, commerce, forensics, and industry. In Hair, Kurt Stenn — one of the world's foremost hair follicle experts — takes readers on global journey through history, from fur merchant associations and sheep farms to medical clinics and patient support groups, to show the remarkable impact hair has had on human life. From a completely bald beauty queen with alopecia to the famed hair-hang circus act, Stenn weaves the history of hair through a variety of captivating examples, with sources varying from renaissance merchants’ diaries to interviews with wig makers, modern barbers, and more. In addition to expelling the biological basis and the evolutionary history of hair, the fiber is put into context: hair in history (as tied to textile mills and merchant associations), hair as a construct for cultural and self-identity, hair in the arts (as the material for artist's brushes and musical instruments), hair as commodity (used for everything from the inner lining of tennis balls to an absorbent to clean up oil spills), and hair as evidence in criminology. Perfect for fans of Mark Kurlansky, Hair is a compelling read based solidly in historical and scientific research that will delight any reader who wants to know more about the world around them.

For all curious readers, a lively introduction to radical ideas and discoveries that are transforming our knowledge of the universe This book provides a tour of the "greatest hits" of cosmological discoveries--the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research--an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes--these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.

The Physicist and the Philosopher

On April 6, 1922, in Paris, Albert Einstein and Henri Bergson publicly debated the nature of time. Einstein considered Bergson's theory of time to be a soft, psychological notion, irreconcilable with the quantitative realities of physics. Bergson, who gained fame as a philosopher by arguing that time should not be understood exclusively through the lens of science, criticized Einstein's theory of time for being a metaphysics grafted on to science, one that ignored the intuitive aspects of time. The Physicist and the Philosopher tells the remarkable story of how this explosive debate transformed our understanding of time and drove a rift between science and the humanities that persists today. Jimena Canales introduces readers to the revolutionary ideas of Einstein and Bergson, describes how they dramatically collided in Paris, and traces how this clash of worldviews reverberated across the twentieth century. She shows how it provoked responses from figures such as Bertrand Russell and Martin Heidegger, and carried repercussions for American pragmatism, logical positivism, phenomenology, and quantum mechanics. Canales explains how the new technologies of the period—such as wristwatches, radio, and film—helped to shape people’s conceptions of time and further polarized the public debate. She also discusses how Bergson and Einstein, toward the end of their lives, each reflected on his rival’s legacy—Bergson during the Nazi occupation of Paris and Einstein in the context of the first hydrogen bomb explosion. The Physicist and the Philosopher is a magisterial and revealing account that shows how scientific truth was placed on trial in a divided century marked by a new sense of time.
