GALILEO GALILEI ( 1564-1642)                              

                      ” Mathematics is the language in which God has written the universe. “
Galileo, Galilei.

The word infinity had been under discussion for more than two millennia in the world of mathematics. Several mathematicians contributed their services to come to solutions about infinity. Greek Mathematicians, sometimes between the fifth and sixth centuries B.C., were the first ones who came up with infinite.  These newly discovered paradoxes and concepts were so contrary to the human intellectual that caused many consequences to the mathematicians of that period. While Greek philosophers discovered many aspects  about the nature of infinity but it was during medieval time that mathematicians made several deep discoveries about mathematical infinity. However, the medival history of science and mathematical revolution would be incomplete if one doesn’t mention one of the greatest scientist of all time Galileo who was the first person dared to discuss the key property of actual infinity.

Galileo Galilei (1564-1642) was a unique mathamtician, philosopher, humanist, and astronomer. He was born in Pisa, Italy on February 15, 1564. He was the oldest son of Vincenzo Galilei, who was  a musician and wool trader of that period.Galileo spent his childhood in Pisa till his family moved  to Florence in 1574. In his middle teens, Galileo attended the monastery school at Vallombrosa, near Florence. Galileo was then sent to the university of Pisa to study Medicine. There, he found his interest in mathematics and decided to make his future within mathematics and sciences without his family’s consent.

After four years, he returned home in Florence with no doctor’s degree in hand. With no option left, he started tutoring math to earn a living. Now he was completely in mathematical field and started reading ancient Greek mathematician and philosophers-Pythagoras, Archimedes and other. He was inspired by the Greek methodologies and pursued their line to make his own discoveries.

By the age of 22, he published his first book, The Little Balance, which was his discoveries in the extension of work done by Archimedes. While tutoring mathematics and publishing his own book made him instantly famous He was,then at age of 25, invited to join the university of Pisa. There, he taught as a math professor and due to some clash with his collegues, few years laters , he moved to university of Padua, near Vanice.
