12. Kepler

Dear Bob, We mathematicians still study Kepler, possibly among the greatest early astronomers, and yet also a student of astrology ( although mostly to debunk it). I think you may be his reincarnation, as he, like you, valued precision and accuracy. He measured the rotation of all the planets recognisable at the time, and hypothesised about Neptune. As for Pluto, its status continues to be in dispute. As a writer, I also plead for you to write a book about your methods, and some suggested approaches to interpreting them. Please continue to contribute your insights!
