49. Discovery of Neptune.a. In what sense was Neptune discovered by mathematics,rather than by a telescope? How did this discovery lend fur-ther support to Newtons theory of gravity? Explain.b. According to the idea known as astrology, the positions ofthe planets among the constellations, as seen from Earth,determine the courses of our lives. Astrologers claim thatthey must carefully chart the motions of all the planets to castaccurate predictions (horoscopes). In that case, say skeptics,astrologers should have been able to predict the existence ofNeptune long before it was predicted by astronomers, sincethey should have noticed inaccuracies in their predictions.But they did not. Do you think this fact tells us anythingabout the validity of astrology? Defend your opinion in aone- to two-page essay.
