Galileo Galilei 1564 -1642 Galileo Galilei was born on February 15, 1564 in Pisa, Italy. Galileo pioneered "experimental scientific method," and was the first to use a refracting telescope to make important astronomical discoveries. In 1604 Galileo learned of the invention of the telescope in Holland. From the barest description he constructed a vastly superior model. With it he made a series of profound discoveries, including the moons of planet Jupiter and the phases of the planet Venus (similar …showed first 75 words of 308 total…

The success with which he applied this technique to the analysis of motion opened the way for modern mathematical and experimental physics. Isaac Newton used one of Galileo's mathematical descriptions, "The Law of Inertia," as the foundation for his "First Law of Motion." Galileo died in 1642, the year of Newton's birth.
