A Flash of Light is an intriguing book that starts at the beginning of time itself and then winds its way through a host of fascinating light related topics including the hues of aliens sunsets, the psychology of colour, and the chemistry of LCD screens. Written as part of a novel experiment, editors Mark Lorch and Andy Miah hatched a plan to collect a critical mass of academics in a room and charged them with writing a popular science book, under the watchful eye of the general public at the Manchester Science Festival. The result is an enlightening look into the science behind colour and light, encompassing biology, chemistry and physics and including simple and fun “try this at home” ideas to illustrate the concepts covered. Drawing on the experience of some of the UK’s best science communicators, this book will appeal to anyone with an interest in science. Its pacey, witty and engaging tone provides illuminating insight into how and why we see the universe the way we do.
