This lyrical and luminously illustrated picture book explores the beauty of the everyday moments in a child’s world. Light can be so many things! The twinkle of a faraway star, a firefly captured in a jar, a mother’s love, a turtle dove... Through this thoughtful and celebratory book, young readers will discover the special glow in everything from nature to the smiles of loved ones. Each page reveals a different sparkle found in a child’s simple but extraordinary world. The light revealed on the final page makes a fitting finale for this sweet, bright tale.

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.

Focusing on the unresolved debate between Newton and Huygens from 300 years ago, The Nature of Light: What is a Photon? discusses the reality behind enigmatic photons. It explores the fundamental issues pertaining to light that still exist today. Gathering contributions from globally recognized specialists in electrodynamics and quantum optics, the book begins by clearly presenting the mainstream view of the nature of light and photons. It then provides a new and challenging scientific epistemology that explains how to overcome the prevailing paradoxes and confusions arising from the accepted definition of a photon as a monochromatic Fourier mode of the vacuum. The book concludes with an array of experiments that demonstrate the innovative thinking needed to examine the wave-particle duality of photons. Looking at photons from both mainstream and out-of-box viewpoints, this volume is sure to inspire the next generation of quantum optics scientists and engineers to go beyond the Copenhagen interpretation and formulate new conceptual ideas about light–matter interactions and substantiate them through inventive applications.

Intended for students in the visual arts and for others with an interest in art, but with no prior knowledge of physics, this book presents the science behind what and how we see. The approach emphasises phenomena rather than mathematical theories and the joy of discovery rather than the drudgery of derivations. The text includes numerous problems, and suggestions for simple experiments, and also considers such questions as why the sky is blue, how mirrors and prisms affect the colour of light, how compact disks work, and what visual illusions can tell us about the nature of perception. It goes on to discuss such topics as the optics of the eye and camera, the different sources of light, photography and holography, colour in printing and painting, as well as computer imaging and processing.

The Scattering of Light and other Electromagnetic Radiation covers the theory of electromagnetic scattering and its practical applications to light scattering. This book is divided into 10 chapters that particularly present examples of practical applications to light scattering from colloidal and macromolecular systems. The opening chapters survey the physical concept of electromagnetic waves and optics. The subsequent chapters deal with the theory of scattering by spheres and infinitely long cylinders. These topics are followed by discussions on the application of light scattering to the determination of the size distribution of colloidal particles. The last chapters are devoted to the Rayleigh-Debye scattering and the scattering by liquids, as well as the concept of anisotropy. These chapters also describe the effect upon light scattering of partial orientation of anisotropic particles in electrical and magnetic fields and in viscous flow. This book is of value to physical chemists and physical chemistry researchers, teachers, and students.

THE INSTANT NEW YORK TIMES BESTSELLER! From Jay Asher, #1 New York Times bestselling author of Thirteen Reasons Why, comes a holiday romance that will break your heart, but soon have you believing in love again. . . . "A beautiful story of love and forgiveness." —Stephen Chbosky, New York Times bestselling author of The Perks of Being a Wallflower Sierra's family runs a Christmas tree farm in Oregon—it's a bucolic setting for a girl to grow up in, except that every year, they pack up and move to California to set up their Christmas tree lot for the season. So Sierra lives two lives: her life in Oregon and her life at Christmas. And leaving one always means missing the other. Until this particular Christmas, when Sierra meets Caleb, and one life eclipses the other. By reputation, Caleb is not your perfect guy: years ago, he made an enormous mistake and has been paying for it ever since. But Sierra sees beyond Caleb's past and becomes determined to help him find forgiveness and, maybe, redemption. As disapproval, misconceptions, and suspicions swirl around them, Caleb and Sierra discover the one thing that transcends all else: true love. What Light is a love story that's moving and life-affirming and completely unforgettable.

What is Light is a collection of poetry about life, love, spiritual growth, and learning to embrace ourselves as spiritual beings who are currently engaged in a human experience.
