What Is Light

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.
