The Sun and the Earth

The debate is still alive: more than 10% of Americans believe the sun revolves around the earth, even as science supports a heliocentric model of our solar system. The history of this debate between supporters of the geocentric versus the heliocentric model is recounted in fascinating and often humorous detail, and also shows the value of the scientific method. Readers learn that Copernicus published his ideas just before his death in order to avoid imprisonment, and that the geocentrists were stumped by Mars, whose orbit seemed to speed up and slow down. The geocentric view is presented, followed by the science behind heliocentrism, which was supported by observable phenomena and new technologies such as the telescope. Vivid photographs and clear diagrams depicting both views, as well as reproductions of historical artwork, support the text.
