Discovering Light

What is light? Where are optics and photonics present in our lives and in nature? What lies behind different optical phenomena? What is an optical instrument? How does the eye resemble an optical instrument? How can we explain human vision? This book, written by a group of young scientists, answers these questions and many more.

Discovering Your Inner light is a training manual on how to grow your intuition from a feeling to a voice so you can grace our earth flowing meant to be. The manual provides you with the words to block social distractions and listen intently as to hear your voice inside. Music raises your vibrations while in your zone which allows message to be received. Immersed in childhood memories so growth of intuition will commence which will have you on your journey to the light inside.

This book is a science text about light for the general reader; it is also an adventure story and a detective story revealing how the secrets of light were uncovered. Readers can share in the thrill of each discovery and learn about some of the myriad applications opened up by these fascinating discoveries, including the telescope, fiber optics, the laser, and even the recent optical detection of gravitational waves from space.With Professor Fortson, distinguished experimental physicist, as your tour guide, follow the journey from the 17th century — when Descartes first calculated the size of the rainbow — to the 20th century, when the quantum theory of light was born. Learn how Huygens, Newton, Planck, Einstein and many other great scientists solved one mystery after another, from the reason underlying the law of refraction to the puzzle of the photoelectric effect. The journey ends with the solution to the most challenging mystery of all: that light is both a wave and a particle — a fascinating finale.

From the very beginning it would seem that God had a plan for America. From its discovery by Europeans to its settlement, from the Revolution to Manifest Destiny, from the stirrings of civil unrest to civil war, America was on a path. In our pluralistic world, when textbooks are being rewritten in ways that obscure the Judeo-Christian beginnings of our country, the books in the Discovering God's Plan for America series help ground young readers in a distinctly evangelical way of understanding early American history. As young readers look at their nation's development from God's point of view, they will begin to have a clearer idea of how much we owe to a very few--and how much is still at stake. These engaging books bring history alive in a way that will inspire young people to do their important part in shaping this nation into the future.

World-leading researchers, including Nobel Laureates, explore the most basic questions of science, philosophy, and the nature of existence.

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.

The chorus of the Christian hymn “Amazing Grace” reads, “I once was lost, but now am found, / Was blind but now I see.” Composed by a minister who formerly worked as a slave trader, the song expresses his experience of divine intervention that ultimately caused him to see the error of his ways. This theme of personal awakening is a feature of countless stories throughout history, where the “lost” and the “blind” are saved from darkness and despair by suddenly seeing the light. In Seeing the Light, Thomas DeGloma explores such accounts of personal awakening, in stories that range from the discovery of a religious truth to remembering a childhood trauma to embracing a new sexual orientation. He reveals a common social pattern: When people discover a life-changing truth, they typically ally with a new community. Individuals then use these autobiographical stories to shape their stances on highly controversial issues such as childhood abuse, war and patriotism, political ideology, human sexuality, and religion. Thus, while such stories are seemingly very personal, they also have a distinctly social nature. Tracing a wide variety of narratives through nearly three thousand years of history, Seeing the Light uncovers the common threads of such stories and reveals the crucial, little-recognized social logic of personal discovery.
