Galileo Galilei - Introduction

Gailleo was an Italian astonomer,physicist, philosopher, engineer, and mathematicion He played a big part in the history of science. He was born on February 15, 1564 in Pisa. By the time he died on January 8, 1642. When he was born there science was pretty much nonexistant but when he died it began to blossom throughout Europe.

Early life

Galileo was the first of six children of Vincenzo Galilei, a famous lutenist, composer, and music theorist, and Giulia Ammannati. 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.


Galileo never completed his degree but instead spent his day studing mathmatics. Later he visited the mathematician Christopher Clavius in Rome and started a correspondence with Guildobaldo del Monte. He applied and was turned down for a position in Bologna, but a few years later in 1589, with the help of Clavius and del Monte, he was appointed to the chair of mathematics in Pisa.

Occupation (continued)

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 where he taught geometry,mechanics, and astronomy until 1610. During this period, Galileo made significant discoveries in both pure funamental science as well as practical applied science . His multiple interests included the study of astrology, which at the time was a discipline tied to the studies of mathematics and astronomy.

Key Events and Historical Impact

Galileo invented many mechanical devices other than the pump, such as the hydrostatic balance. But perhaps his most famous invention was the telescope of which was Invented in 1608. The following year news of the invention of the telescope had already reached Italy; Galileo developed his own device in August.

In Autumn 1609 Galileo makes his first observations using his telescopes and discovers the uneven surface of the moon, and a year later discovers Jupiter as well as four of its moons. By 1612, Galileo observed three more planets that we know as Venus, Saturn, and Neptune.

What made Galileo revolutionary? - Conclusion

Galileo challenged the Church on the geocentric model. Claiming that it was not the Earth that was at the center of the universe, but actually the Sun. This sparked contoversy over the heliocentric model and greatly angered the pope. Several years later the church confessed that Galileo was correct and apoligized. Without Galileo the scientific revolution would not exist and we would not know as we do about what lies outside of our world.
