The Cambridge Companion to Galileo (Cambridge Companions to Philosophy)
Format: PDF / Kindle (mobi) / ePub
This collection of essays is unparalleled in the depth of its coverage of all facets of Galileo's work. A particular feature of the volume is the treatment of Galileo's relationship with the Church. It will be of particular interest to philosophers, historians of science, cultural historians and those in religious studies. New readers and nonspecialists will find this the most convenient, accessible guide to Galileo available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of Galileo.
controversy: First, through this exchange, Galileo managed to really rile the Jesuits, who were quite powerful at this time in the Papal Court. Yet, second, Galileo used some of his best, most insightful prose to defend the patently false theory that the comets were really sublunary phenomena caused by some vagaries of optical refraction. Finally, and importantly, it should be noted that in 1623, Cardinal Maffeo Barberini became Pope Urban VIII. Barberini had sided with Galileo in the Florentine
that because there were and are more than one convention. If we are talking about the conventions we use today, 1642 was the correct year. If we were to talk about the convention normal in Florence in the period, Galileo died in 1641. The Florentines before and after the 17th Century began the year on the 25 th of March, so that January was still 1641 by the rules and norms of Galileo's locale. Then there is the problem of the day of Galileo's death. We change days at midnight, but of course that
had aimed at a causal and mathematical explanation of all motions in terms of weight, force, and velocity and at a synthesis of statics and dynamics into a new science of mechanics. The concept of moment, according to Galluzzi, in fact allowed for a mediation between a geometrical science of weight (statics) stemming from Archimedean sources, and the more dynamical approach of the Aristotelian Mechanical Questions, allowing for the interchageability and compensation of weight by motion. Galileo's
without necessarily appealing to a fideistic position. Certainly, in Galileo's eyes, mathematical demonstrations as such proved that "... the human mind is a work of God and one of the most excellent." Of course, they were infinitely fewer than the mathematical properties of nature which were "... infinite and perhaps but one in their essence and in the Divine mind ... and run through the Divine mind like light in an instant."58 "God is always doing geometry," Plato is said to have remarked.59
opposite, or retrograde motion along the inclined plane of the ecliptic. According to this geocentric theory, planets appear to move from west to east sometimes faster, sometimes slower - and pass from the Sun through angles of divergence: ... And he gave the supremacy to the revolution of the Same and uniform ... In order that Time might be brought into being, Sun and Moon and five other stars... were made to define and preserve the numbers of Time. Having made a body for each of them, the god
