In Spectrums, David Blatner blends narrative and illustration to illuminate the variety of spectrums that affect our lives every day: numbers, size, light, sound, heat, and time. There is actually very little in this universe that we can feel, touch, see, hear, or possibly even comprehend. It’s not an easy task to stretch the mind to encompass both billions of years and billionths of seconds; the distance to Jupiter and the size of a proton; the tiny waves of visible light and gargantuan but invisible gamma rays; or the freezing point of Helium and the heat generated by the blast of an atom bomb. Exploring these far-reaching spectrums gives us fascinating perspective on our small but not insignificant place in the universe. With easy-to-read, engaging, and insightful observations, illustrated by a wealth of photographs and diagrams, Blatner helps us “grok”—understand intuitively—six spectrums we encounter constantly, making our daily lives richer and more meaningful through greater appreciation of the bizarre and beautiful world in which we live.
