From the earliest recorded theories and experiments to the latest applications in photonic communication and computation, the ways in which light has been put to use are numerous and astounding. Indeed, some of the latest advances in light science are in fields that until recently belonged to the realm of science fiction. The author, writing for an audience of both students and other scientifically interested readers, describes fundamental investigations of the nature of light and ongoing methods to measure its speed as well as the emergence of the wave theory of light and the complementary photon theory. The importance of light in the theory of relativity is discussed as is the development of electrically-driven light sources and lasers. The information here covers the range o f weak single-photon light sources to super-high power lasers and synchrotron light sources. Many cutting-edge topics are also introduced, including entanglement-based quantum communication through optical fibers and free space, quantum teleportation, and quantum computing. The nature and use of 'squeezed light' - e.g. for gravitational wave detection - is another fascinating excursion, as is the topic of fabricated metamaterials, as used to create invisibility cloaks. Here the reader also learns about the realization of extremely slow speed and time-reversed light. The theories, experiments, and applications described in this book are, whenever possible, derived from original references. The many annotated drawings and level of detail make clear the goals, procedures, and conclusions of the original investigators. Where they are required, all specialist terms and mathematical symbols are defined and explained. The final part of the book covers light expe riments in the free space of the cosmos, and also speculates about scenarios for the cosmological origins of light and the expected fate of the photon in a dying universe.

Chosen as a Book of the Year by The Times, Daily Telegraph, TLS, BBC History Magazine and Tablet 'Compulsive, brilliantly clear and superbly well-written, it's a charismatic evocation of another world' Ian Mortimer, author of The Time Traveller's Guide to Medieval England The Middle Ages were a time of wonder. They gave us the first universities, the first eyeglasses and the first mechanical clocks as medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky. In this book, we walk the path of medieval science with a real-life guide, a fourteenth-century monk named John of Westwyk - inventor, astrologer, crusader - who was educated in England's grandest monastery and exiled to a clifftop priory. Following the traces of his life, we learn to see the natural world through Brother John's eyes: navigating by the stars, multiplying Roman numerals, curing disease and telling the time with an astrolabe. We travel the length and breadth of England, from Saint Albans to Tynemouth, and venture far beyond the shores of Britain. 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. An enthralling story of the struggles and successes of an ordinary man and an extraordinary time, The Light Ages conjures up a vivid picture of the medieval world as we have never seen it before.
