A quick biography of Galileo Galilei.

Galileo's early life

Galileo was born in Pisa, Italy on February 15, 1564. His father, Vincenzo Galilei , was a musician. Galileo's mother was Giulia degli Ammannati. Galileowas the first of six (though some people believe seven) children. His family belonged to the nobility but was notrich. In the early 1570's, he and his family moved to Florence .

The pendelum

n 1581, Galileo began studying at the University of Pisa, where his father hoped he would study medicine. While at theUniversity of Pisa, Galileo began his study of the pendulum while, according to legend, he watched a suspended lamp swing back and forth in thecathedral of Pisa. However, it was not until 1602 that Galileo made his most notable discovery about the pendulum - theperiod (the time in which a pendulum swings back and forth) does not depend on the arc of the swing (theisochronism). Eventually, this discovery would lead to Galileo's further study of time intervals and the developmentof his idea for a pendulum clock.

In 1581, Galileo began studying at the University of Pisa, where his father hoped he would study medicine. While at theUniversity of Pisa, Galileo began his study of the pendulum while, according to legend, he watched a suspended lamp swingback and forth in the cathedral of Pisa. However, it was not until 1602 that Galileo made his most notable discovery aboutthe pendulum - the period (the time in which a pendulum swings back and forth) does not depend on the arc of the swing (theisochronism). Eventually, this discovery would lead to Galileo's further study of time intervals and the developmentof his idea for a pendulum clock.

Mechanical devices

In 1592, Galileo was appointed professor of mathematics at the University of Padua. While teaching there, he frequentlyvisited a place called the Arsenal, where Venetian ships were docked and loaded. Galileo had always been interested inmechanical devices. Naturally, during his visits to the Arsenal, he became fascinated by nautical technologies, suchas the sector and shipbuilding. In 1593, he was presented with the probleminvolving the placement of oars in galleys. He treated the oar as a lever and correctly made the water the fulcrum. A yearlater, he patented a model for a pump . His pump was a device that raised water by using only one horse.

Family life

Galileo was never married. However, he did have a brief relationship with Marina Gamba , a woman he met on one of his many trips to Venice. Marinalived in Galileo's house in Padua where she bore him three children. His two daughters, Virginia and Livia, were both putin convents where they became, respectively, Sister Maria Celeste and Sister Arcangela. In 1610, Galileo moved from Padua to Florence wherehe took a position at the Court of the Medici family . He left his son, Vincenzio, with Marina Gamba in Padua. In 1613, Marina marriedGiovanni Bartoluzzi, and Vincenzio joined his father in Florence.

Telescope

Galileo invented many mechanical devices other than the pump, such as the hydrostatic balance . But perhaps his most famous invention was the telescope . Galileo made his first telescope in 1609, modeled after telescopes produced in otherparts of Europe that could magnify objects three times. He created a telescope later that same year that could magnifyobjects twenty times. With this telescope, he was able to look at the moon , discover the four satellites of Jupiter , observe a supernova, verify the phases of Venus, and discover sunspots . His discoveries proved the Copernican system which states that the earth and other plaqnets revolve around thesun. Prior to the Copernican system, it was held that the universe was geocentric, meaning the sun revolved around theearth.

The inquisition

Galileo's belief in the Copernican System eventually got him into trouble with the Catholic Church. The Inquisition was a permanent institution in the Catholic Church charged with theeradication of heresies. A committee of consultants declared to the Inquisition that the Copernican proposition that theSun is the center of the universe was a heresy. Because Galileo supported the Copernican system, he was warned by Cardinal Bellarmine , under order of Pope Paul V, that he should not discuss or defendCopernican theories. In 1624, Galileo was assured by Pope Urban VIII that he could write about Copernican theory as long as he treated it as amathematical proposition. However, with the printing of Galileo's book, Dialogue Concerning the Two Chief World Systems , Galileo was called to Rome in 1633 to face the Inquisition again. Galileo was found guilty of heresy for hisDialogue, and was sent to his home near Florence where he wasto be under house arrest for the remainder of his life. In 1638, the Inquisition allowed Galileo to move to his home inFlorence, so that he could be closer to his doctors. By that time he was totally blind. In 1642, Galileo died at his homeoutside Florence.
