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.
To read this book is to encounter the essence of our lives and our everyday concerns. Toni Packer shines her gentle light on fear, compassion, impermanence, attraction, prejudice, enlightenment, and much more as she invites us into our own light of discovery. As she says, "In truth we are not separate from each other, or from the world, from the whole earth, the sun or moon or billions of stars, not separate from the entire universe. Listening silently in silent wonderment, without knowing anything, there is just one mysteriously palpitating aliveness."
A Choice Outstanding Academic Book, 1997
An American novelist marries his London editor and finds out that her past is more complicated than he knew when she suddenly leaves to visit her sister in New York, and is mysteriously killed by a subway train
Kirkus Star Junior Library Guild Gold Selection Mark Weston’s high-interest story and Rebecca Evans’s colorful graphics make scientific discovery the coolest thing this side of Jupiter. More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn’t even believe that light traveled? Like many paradigm-shattering discoveries, Romer’s was accidental. Night after night he was timing the disappearance and reappearance of Jupiter’s moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light’s speed was some fancy geometry.
