First published Fri Mar 4, 2005; substantive revision Wed May 10, 2017. Galileo Galilei (1564â1642) has always played a key role in any history of science and, in many histories of philosophy, he is a, if not the, central figure of the scientific revolution of the 17th Century. His work in physics or natural philosophy, astronomy, and the methodology of science still evoke debate after over 400 years.
Galileo pioneered experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. In 1609 Galileo learned of the invention of the telescope in Holland. From the barest description he constructed a vastly superior model. Galileo made a series of profound discoveries using his new telescope, including the moons of the planet Jupiter and the phases of the planet Venus (similar to those of Earth's moon).
