Galileo: Galileo Galilei
built 628 days ago
Galileo Galilei's parents were Vincenzo Galilei and Guilia Ammannati. Vincenzo, who was born in Florence in 1520, was a teacher of music and a fine lute player. After studying music in Venice he carried out experiments on strings to support his musical theories. Guilia, who was born in Pescia, married Vincenzo in 1563 and they made their home in the countryside near Pisa. Galileo was their first child and spent his early years with his family in Pisa.

Galileo Galilei (1564-1642) [W]as the oldest of seven children born to Vincenzo Galilei and Giulia Ammanati. He entered the University of Pisa in 1581 to study medicine. Soon he realized that his interests were not in medicine, but mathematics. After only a year in the university, he made his famous discovery of the isochronal movement of pendulums.

The Galileo spacecraft was designed to study Jupiter's atmosphere, satellites, and surrounding magnetosphere for two years. The spacecraft was named in honor of Galileo Galilei, the Italian Renaissance scientist who discovered Jupiter's major moons in 1610. The Galileo spacecraft was carried into space by the shuttle Atlantis on October 18, 1989. Once released from the cargo bay, a two-stage Inertial Upper Stage (IUS) booster fired to accelerate the spacecraft out of Earth orbit toward the planet Venus. From there, Galileo will spend more than five years traveling to Jupiter, where it will become the first spacecraft to make direct measurements from an instrumented probe within Jupiter's atmosphere. It will ... become the first spacecraft to conduct long-term observations of Jupiter, its magnetosphere, and satellites from orbit around Jupiter.

Galileo Galilei (1564-1642 A.D.) received a broad Renaissance education. Until 1610, when Galileo built his first telescope at age 46, he focused mainly on physics, not astronomy. He soon made discoveries which shook the foundations of the Aristotelian cosmos. He saw mountains, valleys and other features indicating change on the moon. He observed the motion of four of Jupiter's moons, now referred to as the Galilean moons. No longer could scientists say that heavenly bodies revolve exclusively around the earth.

Galileo was born in Pisa (then part of the Grand Duchy of Tuscany), the first of six children of Vincenzo Galilei, a famous lutenist and music theorist, and Giulia Ammannati. At the age of 8, his family moved to Florence, but he was left with Jacopo Borghini for two years.[1] He then was educated in the Camaldolese Monastery at Vallombrosa, 33km southeast of Florence.[1] Although he seriously considered the priesthood as a young man, he enrolled for a medical degree at the University of Pisa at his father's urging. He did not complete this degree, but instead studied mathematics. In 1589, he was appointed to the chair of mathematics in Pisa. In 1591 his father died and he was entrusted with the care of his younger brother Michelagnolo. In 1592, he moved to the University of Padua, teaching geometry, mechanics, and astronomy until 1610.

Galileo Galilei was born in Pisa in 1564, in the same year as Shakespeare, and died in 1642, the birth year of Isaac Newton, his scientific successor. His father was a music teacher and his family of minor noble blood, though not wealthy. In 1581, Galileo began studying at the University of Pisa, where his father hoped he might pursue medicine. But mathematics and science, especially when coupled with a keen observation of nature, proved too powerful a lure for him. Legend has it that, while still a student, Galileo became intrigued by pendulums when he saw a suspended lamp swinging back and forth in the city’s cathedral. Timing the swings with his own pulse, the story goes, he found that the period (the time in which the pendulum completes one trip back and forth) is independent of the arc of the swing.
