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 17 th Century.t was during his Paduan period that Galileo worked out much of his mechanics and began his work with the telescope. In 1610 he published The Starry Messenger, and soon after accepted a position as Mathematician and Philosopher to the Grand Duke of Tuscany (and a non-teaching professorship at Pisa).
Galileo's development of a telescope and his unorthodox opinions as a philosopher of science were the central concerns of his career and the subjects of the four writings included in this book. He addressed these writings to contemporary laymen.
