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 ...
The secretary to Giovanni Antonio Magini, a Bohemian astronomer named Martin Horký, published an incendiary pamphlet criticizing the Sidereus Nuncius, alleging in it that Galileo's observations were the result of poor lenses and influenced by personal ambitions. After gaining some traction in Italy, however, Horky's work was ultimately ...
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.

He is named after Galileo's friend Filippo Salviati (1582–1614). Sagredo is an intelligent layman who is initially neutral. He is named after Galileo's friend Giovanni Francesco Sagredo (1571–1620). Simplicio, a dedicated follower of Ptolemy and Aristotle, presents the traditional views and the arguments against the Copernican position.
In his letter to Benedetto Castelli, Galileo argues that using the Bible as evidence against the Copernican system involves three key errors. Firstly, claiming that the Bible shows the Earth to be static and concluding that the Earth therefore does not move is arguing from a false premise; whether the Earth moves or not is a thing which must be demonstrated (or not) through scientific enquiry.
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.
