Brief Biography Galileo was born on February 15, in Pisa. By the time he died on January 8, but see problems with the date, Machamerpp. Galileo and his family moved to Florence in
Galileo became an accomplished lutenist himself and would have learned early from his father a scepticism for established authority,  the value of well-measured or quantified experimentation, an appreciation for a periodic or musical measure of time or rhythm, as well as the results expected from a combination of mathematics and experiment.
Three of Galileo's five siblings survived infancy.
The youngest, Michelangelo or Michelagnoloalso became a noted lutenist and composer although he contributed to financial burdens during Galileo's young adulthood. Michelangelo was unable to contribute his fair share of their father's promised dowries to their brothers-in-law, who would later attempt to seek legal remedies for payments due.
Michelangelo would also occasionally have to borrow funds from Galileo to support his musical endeavours and excursions.
These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income. When Galileo Galilei was eight, his family moved to Florencebut he was left with Jacopo Borghini for two years.
The Italian male given name "Galileo" and thence the surname "Galilei" derives from the Latin "Galilaeus", meaning "of Galilee ", a biblically significant region in Northern Israel. In it he made a point of quoting Acts 1: She is buried with him in his tomb in the Basilica of Santa Croce, Florence.
Despite being a genuinely pious Roman Catholic,  Galileo fathered three children out of wedlock with Marina Gamba. They had two daughters, Virginia born in and Livia born inand a son, Vincenzo born in Both girls were accepted by the convent of San Matteo in Arcetri and remained there for the rest of their lives.
Livia took the name Sister Arcangela and was ill for most of her life. Vincenzo was later legitimised as the legal heir of Galileo and married Sestilia Bocchineri.
To him, it seemed, by comparison with his heartbeat, that the chandelier took the same amount of time to swing back and forth, no matter how far it was swinging.
When he returned home, he set up two pendulums of equal length and swung one with a large sweep and the other with a small sweep and found that they kept time together.
It was not until the work of Christiaan Huygensalmost one hundred years later, that the tautochrone nature of a swinging pendulum was used to create an accurate timepiece. However, after accidentally attending a lecture on geometry, he talked his reluctant father into letting him study mathematics and natural philosophy instead of medicine.
Galileo also studied disegno, a term encompassing fine art, and, inobtained the position of instructor in the Accademia delle Arti del Disegno in Florence, teaching perspective and chiaroscuro. Being inspired by the artistic tradition of the city and the works of the Renaissance artists, Galileo acquired an aesthetic mentality.
While a young teacher at the Accademia, he began a lifelong friendship with the Florentine painter Cigoliwho included Galileo's lunar observations in one of his paintings.
Inhis father died, and he was entrusted with the care of his younger brother Michelagnolo. Inhe moved to the University of Padua where he taught geometry, mechanicsand astronomy until His multiple interests included the study of astrologywhich at the time was a discipline tied to the studies of mathematics and astronomy.
Cardinal Bellarmine had written in that the Copernican system could not be defended without "a true physical demonstration that the sun does not circle the earth but the earth circles the sun".
For Galileo, the tides were caused by the sloshing back and forth of water in the seas as a point on the Earth's surface sped up and slowed down because of the Earth's rotation on its axis and revolution around the Sun.
He circulated his first account of the tides inaddressed to Cardinal Orsini.About. Welcome to Planet Four, a citizen science project designed to help planetary scientists identify and measure features on the surface of Mars the likes of which don’t exist on Earth. Overview. In Depth.

This book evaluates historical knowledge as it relates to ancient and modern genealogies. Information gleaned from social contexts, both secular and religious, are reviewed, using modern genealogical research specialist standards: to properly reconstruct and correctly portray real historical lives and family pedigrees.

Galileo, in full Galileo Galilei, (born February 15, , Pisa [Italy]—died January 8, , Arcetri, near Florence), Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method.
Galileo then became interested in optics and astronomy, and in he built his first telescope and began making observations. The following year he published his first results, where he described the highlands and "seas" of the Moon, four of Jupiter's largest moons, and many newly discovered stars.
