Galileo Starts Work on Dialogue of the Tides (later renamed by enemies to Dialogue of the Two Chief World Systems)
Author: Galilei Galileo, Italian Physicist and Astronomer
My friend Maffeo Barberini has been elected Pope Urban VIII today. It is a beneficial occasion for me because I have some political support now. I have wanted to put my defense of Copernicanism down on paper for quite a while, so I am starting this evening on the Dialogue of the Tides.
Let's hope that Barberini can hold those Jesuits back because Dialogue of the
Tides will be very undermining to their Aristotelian curriculum. The book will use some of the data I used in The Starry Messenger such as comet paths, Jupiter's moons, and a irregular moon surface to expound the heliocentric view of Copernicus, which supports my tide theory that relies on the motion of the Earth.
I believe my work will revolutionize science by using mathematical calculations instead of personal observations. Mathematics cannot lie or create false conceptions, as opposed to personal observations which are fallible It represents the ultimate truth. My work in all of this has been to mathematize nature and geometrize space. My study of projectiles and free-falling bodies fits very well with heliocentricism and justifies it.
I believe Kepler is at the moment writing Rudolfine Tables, which uses Brahe's data to predict the position of a planet to within less than a degree. That would be very informative. I must now write a letter to congratulate Barberini. Hooray!
