Light
by R. W. DitchburnThis classic study, available for the first time in paperback, clearly demonstrates how quantum theory is a natural development of wave theory, and how these two theories, once thought to be irreconcilable, together comprise a single valid theory of light. Aimed at students with an intermediate-level knowledge of physics, the book first offers a historical introduction to the subject, then covers topics such as wave theory, interference, diffraction, Huygens' Principle, Fermat's Principle, and the accuracy of optical measurements. Additional topics include the velocity of light, relativistic optics, polarized light, electromagnetic theory, and the quantum theory of radiation. The more difficult mathematics has been placed in appendixes, or in separated paragraphs in small type, intended to be omitted on first reading. Examples and/or references follow each chapter to assist the student in absorbing the material and to suggest additional resources.
Light: Physical Science)

The Light Ages: The Surprising Story Of Medieval Science
by Seb FalkAn illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

Light and Death: Figuration in Spenser, Kepler, Donne, Milton
by Judith H. AndersonLight figures being; darkness, death. Bridging mathematical science, semantics, rhetoric, grammar, and major poems, Judith H. Anderson seeks to negotiate writings from multiple disciplines in the shared terms of poiesis and figuration rather than as cultural opposites. Analogy, a type of metaphor, has always been the connector of the known to the unknown, the sensible to the infinite. Anderson’s study moves from the figuration of light and death to the history of analogy and its pertinence to light in physics and metaphysics, from Kepler to Donne, Spenser, and Milton. Topics proliferate: creativity, optics, the relation of literature to science, the methodology of thought and argument, and the processes of narrative, discovery, and interpretation.

Light And Sound: Color And Sound All Around
by Rebecca L. JohnsonLight waves are transverse. Their properties include wavelength, frequency, and amplitude. Light waves can be absorbed, reflected, or refracted. An object's color depends on the colors of white light it absorbs and reflects. Sound travels through matter as compression waves. The frequency and amplitude of sound waves are related to the pitch and volume of sounds.
Light and Sound: Reflection And Refraction
by Rebecca L. JohnsonLight is energy you can see. Light waves are transverse, and they move energy forward. Light waves can be absorbed, reflected, or refracted. Sound is energy you can hear. Sound waves are compression waves. They push together and spread apart. Properties of light and sound waves are wavelength, amplitude, and frequency.
Light And Sound Energy Waves
by Rebecca L. JohnsonLight and sound are waves of moving energy. Light is a form of energy you can see. Light waves travel in straight lines away from a light source. Sound is a form of energy you can hear. Sound happens when particles of matter vibrate. Properties of light and sound waves include wavelength, frequency, and amplitude.
Light and Specular Microscopy of the Cornea
by Katerina JirsovaThe atlas of the light and specular microscopy of the cornea, particularly of the corneal endothelium presents healthy and pathological corneas as well as corneas prepared for grafting; photographs are taken from donor or patient's corneas. The first section of the atlas shows healthy cornea and its particular layers: the epithelium (superficial and basal cells, subepithelial nerve plexus), stroma and keratocytes, and the endothelium. Blood vessels or palisades of Vogt in limbus are shown as well. The second section that shows corneas processed for grafting is focused on the endothelial layer. The main causes of exclusion of corneas from grafting, such as the presence of dead cells, polymeghatism, pleomorphism, cornea guttata or stromal scars have been shown. The third section shows corneas before and after storage in tissue cultures or hypothermic conditions with the aim to assess suitability of tissue for grafting. Finally, the last section contains photographs of pathological corneal explants.
Light and Waves: A Conceptual Exploration of Physics
by Steven S. AndrewsThis book explores light and other types of waves, using this as a window into other aspects of physics. It emphasizes a conceptual understanding, using examples chosen from everyday life and the natural environment. For example, it explains how hummingbird feathers create shimmering colors, how musical instruments produce sound, and how atoms stick together to form molecules. It provides a unique perspective on physics by emphasizing commonalities among different types of waves, including string waves, water waves, sound waves, light waves, the matter waves of quantum mechanics, and the gravitational waves of general relativity. This book is targeted toward college non-science majors, advanced high school students, and adults who are curious about our physical world. It assumes familiarity with algebra but no further mathematics and is classroom-ready with many worked examples, exercises, exploratory puzzles, and appendices to support students from a variety of backgrounds.

Read it!” –Elizabeth Kolbert, author of Under a White Sky and The Sixth Extinction Award-winning Atlantic staff writer Zoë Schlanger delivers a groundbreaking work of popular science that probes the hidden world of the plant kingdom, “destabilizing not just how we see the green things of the world but also our place in the hierarchy of beings, and maybe the notion of that hierarchy itself.” (The New Yorker)It takes tremendous biological creativity to be a plant. To survive and thrive while rooted in a single spot, plants have adapted ingenious methods of survival. In recent years, scientists have learned about their ability to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit, to name just a few remarkable talents.The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system. What is intelligent life if not a vine that grows leaves to blend into the shrub on which it climbs, a flower that shapes its bloom to fit exactly the beak of its pollinator, a pea seedling that can hear water flowing and make its way toward it? Zoë Schlanger takes us across the globe, digging into her own memories and into the soil with the scientists who have spent their waking days studying these amazing entities up close.What can we learn about life on Earth from the living things that thrive, adapt, consume, and accommodate simultaneously? More important, what do we owe these life forms once we come to understand their rich and varied abilities? Examining the latest epiphanies in botanical research, Schlanger spotlights the intellectual struggles among the researchers conceiving a wholly new view of their subject, offering a glimpse of a field in turmoil as plant scientists debate the tenets of ongoing discoveries and how they influence our understanding of what a plant is.We need plants to survive. But what do they need us for—if at all? An eye-opening and informative look at the ecosystem we live in, this book challenges us to rethink the role of plants—and our own place—in the natural world.

Light in the Darkness: Black Holes, the Universe, and Us
by Heino Falcke Jörg RömerAn astrophysicist chronicles his quest to photograph a black hole and reflects on its spiritual ramifications in this international-bestselling memoir.On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference—a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.Light in the Darkness takes us on Falcke’s extraordinary journey to the darkest corners of the universe. From the first humans looking up at the night sky to modern astrophysics, from the study of black holes to the still-unsolved mysteries of the universe, Falcke asks, in even the greatest triumphs of science, is there room for doubts, faith, and a God? A plea for curiosity and humility, Light in the Darkness sees one of the great minds shaping the world today as he ponders the big, pressing questions that present themselves when we look up at the stars.
Light in the Darkness: Black Holes, The Universe and Us
by Professor Heino Falcke Jörg RömerAs featured in THE EDGE OF ALL WE KNOW - the new Netflix documentary about Black HolesFor readers of Stephen Hawking, a fascinating account of the universe from the perspective of world-leading astrophysicist Heino Falcke, who took the first ever picture of a black hole.10th April 2019: a global sensation. Heino Falcke, a man "working at the boundaries of his discipline and therefore at the limits of the universe" had used a network of telescopes spanning the entire planet to take the first picture of a black hole.Light in the Darkness examines how mankind has always looked to the skies, mapping the journey from millennia ago when we turned our gaze to the heavens, to modern astrophysics. Heino Falcke and Jorg Romer entertainingly and compellingly chart the breakthrough research of Falcke's team, an unprecedented global community of international colleagues developing a telescope complex enough to look directly into a black hole - a hole where light vanishes, and time stops.What does this development mean? Is this the beginning of a new physics? What can we learn from this about God, the world, and ourselves? For Falcke, astrophysics and metaphysics, science and faith, do not exclude one another. Black Hole is both a plea for curiosity and humility; it's interested in both what we know, and the mysteries that remain unsolved.
