A review of David A. Weintraub’s Is Pluto a Planet?

This is the first review of the literature on Pluto. Here I look at David Weintraub’s Is Pluto a Planet? Weintraub supports Pluto’s planetary status and is, probably, still upset that the IAU’s definition of a planet excludes Pluto.

Kepler on supernova, theology and astrology

Johannes Kepler, who was born on 27 December 1571, is the subject of a couple recent interesting articles. These articles are an opportunity to see how Kepler was typical of the early-modern European scholar, a person as interested in astronomy and optics (our notion of sciences) as theology and astrology.

What is the case for Pluto?

A review of Alan Boyle’s The Case for Pluto, which is readable and enjoyable. As he makes clear in the title, he favors a definition of a planet that would include Pluto, as well as an indeterminate number of yet-to-be-discovered objects orbiting our sun as well as other stars.
