The Starry Messenger Showing Forth Great and Truly Wonderful Sights, as Well as Suggesting to Everyone, but Especially to Philosophers, Things to be Pondered
Galileo Galilei (1564–1642) was an Italian astronomer, mathematician, physicist, philosopher, and inventor. He revolutionized the sciences in the Western world by using mathematics and experimental evidence in the study of natural phenomena. Born in Pisa, Galileo studied in Pisa and Florence and in 1589 was appointed to the chair of mathematics at the University of Pisa. In 1591 he moved to the University of Padua, where he completed much of his most important scientific work. In late 1609, Galileo perfected a telescope of 30x magnification, with which he quickly ...

Works of Galileo Galilei, Part 3, Volume 5, Astronomy: Observations and Related Calculations about the Medicean Planets
This manuscript contains observations and calculations made by the Italian scientist and mathematician Galileo Galilei (1564–1642) on the so-called Medicean Planets—the satellites rotating around the planet Jupiter that Galileo discovered using the powerful telescope he invented and built in late 1609. Galileo made these notes in the course of his intense astronomical studies of early 1610, when he was in the last months of his tenure of the chair of mathematics at the University of Padua. These observations were then synthesized in his Sidereus Nuncius (Starry messenger), published ...
