Spectrums

Any broad range of characteristics can be defined as a spectrum. In his new book, David Blatner investigates spectrums including numbers, light, sound, temperature, distance and time. With typical humour and insight he investigates the extraordinary universe we live in and shows how to understand the apparently inconceivable. Did you know that ...if the earth was the size of a grain of salt, our solar system would be 450 miles wide? ...no matter how chilly it is outside, it's physically impossible to reach to a temperature of absolute zero? ...the colour magenta doesn't really exist? ...the ancient Egyptians not only knew that the Earth was round, but actually calculated its circumference? With easy-to-read, fun, and insightful observations, Blatner rediscovers the bizarre and beautiful world in which we live.
