450th Anniversary of the birth of Galileo Galilei

Galileo Galilei was the father of the modern experimental science, but also a philosopher, a literary critic, a lutenist and a poet. He became a symbol of the dogmatism opposers, supporter of research and progress and his discoveries are still today food for thought and study. On the occasion of the 450th anniversary of the birth of Galileo Galilei (1564-1642), the Ufficio Filatelico Numismatico of the Republic of San Marino dedicates to the revolutionary scientist 2 stamps of € 0.70 in order to honour his memory, his deeds and the extraordinary self-denial by which he immolated himself as master of reason and prepared the ground to the modern science. In 1597 he invented in Padua the geometrical compass for arithmetical and geometrical calculations. In 1609 Galileo Galilei showed to the government of Venice his telescope, with which for the first time it was possible to scan the cosmos deeply. Through those astronomical observations he confuted the Aristotelian geocentric view that the Earth was the center of the universe and that all heavenly bodies revolved around the Earth and supported the astronomical model of heliocentricism, in which the Earth and planets revolve around a relatively stationary Sun at the center of the Solar System. This discovery revolutionized the knowledge and the world perception and led him to the sentence for heresy by the ecclesiastical authorities.
