About this book
The Music of the Spheres, by Florence Armstrong Grondal, is A Nature Lover's Astronomy. Chapter IV is titled The Two Sky Dippers and Draco, the Dragon. A section on the Big Dipper says this Dipper is ornamented with seven bright stars, although a telescope or a field-glass will disclose dozens more encrusted on its handle and a starry phosphorescence in its bowl.
The text says it is believed that the great pyramid of Cheops, built 4600 years ago, was so constructed that the light of Thuban, then the Pole Star, would shine down its great stone tube. The text says a train traveling 60 miles an hour would reach the sun in 176 years, and an airplane flying at the rate of 200 miles an hour would reach it in 50 years. The text says the earth travels in a long journey around the sun, surmised by Copernicus in 1530 and proved by Kepler and Galileo about 1610.
