Galileo Galilei (1564-1642) revolutionised our view of the natural world in many respects. Some call him the father of modern physics. However, contrary to common opinion, Galileo did not invent the telescope, nor was he the first to use it for the observation of the heavens. None the less, his use of the instrument revolutionised astronomy and shook the foundations of a religiously supported belief in a geocentric world. Man was no longer at the centre of the universe. The talk will discuss Galileo’s telescopic observations, but particularly his “Dialogue Concerning the Two Chief World Systems: Ptolemaic and Copernican” (1632) which “gives an extremely lively and persuasive exposition of the then prevailing views on the structure of the cosmos in the large” (Einstein). Its content formed the basis for his condemnation by the Roman Catholic Church in 1633.
