His friendship with Galileo began to take second place to his feelings of persecution and fear for his own life. The problem of Galileo was presented to the pope by court insiders and enemies of Galileo, following claims by a Spanish cardinal that Urban was a poor defender of the church. This situation did not bode well for Galileo's defense of ...
Galileo was born in Pisa (then part of the Duchy of Florence) on 15 February 1564, [20] 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.
"And yet it moves" or "Although it does move" (Italian: E pur si muove or Eppur si muove [epˈpur si ˈmwɔːve]) is a phrase attributed to the Italian mathematician, physicist, and philosopher Galileo Galilei (1564–1642) in 1633 after being forced to recant his claims that the Earth moves around the Sun, rather than the converse.
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.
Pope Paul V (Latin: Paulus V; Italian: Paolo V) (17 September 1550 – 28 January 1621), born Camillo Borghese, was head of the Catholic Church and ruler of the Papal States from 16 May 1605 to his death, in January 1621. In 1611, he honored Galileo Galilei as a member of the papal Accademia dei Lincei and supported his discoveries. [2]
Vincenzo or Vincenzio Gamba (1606–1649), later Vincenzo Galilei (1619), was the illegitimate son of Galileo Galilei (1564–1642) and his mistress Marina Gamba (1570–1612). Vincenzo was legitimated to his father in 1619. Like his grandfather Vincenzo Galilei, the younger Vincenzo became a lutenist.
In his 1651 work Almagestum Novum, Giovanni Battista Riccioli set out 126 arguments against the Copernican model of the universe. In his 43rd argument, Riccioli considered the points Galileo had made in his Letters on Sunspots, and asserted that a heliocentric (Copernican) explanation of the phenomenon was more speculative, while a geocentric ...
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.
