Physics, Light & Sound, Reference, Science & Math 

This guide to the story of light in which photography of original equipment, intricate scientific instruments, revealing experiments and 3-D models offer a unique view to the incredible discoveries that have transformed our world. See why ancient peoples worshipped the Sun as a God; how light rays bend; why things glow when they are very hot; what creates a colour television picture; how microscopes and telescopes were invented ; why a leaf looks green; how fibre optics can transmit light; what happens during an eclipse; why images are reversed in mirrors; how a liquid crystal display works; what makes a hologram; what causes the eerie "will o" the wisp"; how do some animals make their own light; what creates a mirage; why we burn in strong sunlight; what a polarising filter does; why we see rainbows; what a quantum is and how X-rays penetrate our bodies. - from Amzon
