Galileo was born in Pisa (then part of the Duchy of Florence) on 15 February 1564, [16] the first of six children of Vincenzo Galilei, a leading lutenist, composer, and music theorist, and Giulia Ammannati, the daughter of a prominent merchant, who had married two years earlier in 1562, when he was 42, and she was 24.
Without reference to Galileo's tidal theory, there would be no difference between the Copernican and Tychonic systems. Galileo fails to discuss the possibility of non-circular orbits, although Johannes Kepler had sent him a copy of his 1609 book, Astronomia nova, in which he proposes elliptical orbits—correctly calculating that of Mars. [15]
Galileo's thought experiment concerned the outcome (c) of attaching a small stone (a) to a larger one (b) Galileo set out his ideas about falling bodies, and about projectiles in general, in his book Two New Sciences (1638). The two sciences were the science of motion, which became the foundation-stone of physics, and the science of materials ...
Galileo establishes two main premises before addressing his conclusion. God has created Scripture and nature. They cannot contradict each other. Nature is independent of accommodation, but Scripture is produced to accommodate. [2] Galileo argued that the Copernican theory was not just a mathematical calculating tool, but a physical reality.
Galileo attempted to mathematically map Dante's description of hell, trying to bridge the Divine Comedy and scientific thinking. According to professor Mark Peterson, Galileo may have had a secondary aim, to attack the cosmological model of hell proposed by Alessandro Vellutello of Lucca , while supporting another model by the Florentine ...
The Assayer (Italian: Il saggiatore) is a book by Galileo Galilei, published in Rome in October 1623. It is generally considered to be one of the pioneering works of the scientific method, first broaching the idea that the book of nature is to be read with mathematical tools rather than those of scholastic philosophy, as generally held at the time.

Galileo was the first to investigate the timekeeping properties of pendulums, beginning around 1603. [4] His interest was sparked by his discovery that, at least for small swings, the pendulum is isochronous: its period of swing is the same for different size swings. He realized that this property made the pendulum useful for timekeeping.
