![]() His public advocacy of this view met with strong opposition. Since this new star displayed no detectable diurnal parallax, Galileo concluded that it was a distant star, and therefore disproved the Aristotelian belief in the immutability of the heavens. In 1604, Galileo was able to observe Kepler’s supernova. ![]() ![]() Galileo e Viviani, 1892, Tito Lessi Kepler’s Supernova and Jupiter Nevertheless, despite these flaws, it was still good enough for Galileo also to explore the nocturnal sky – which made Galileo’s design for the time being the best telescope on the contemporary market. Because of flaws in the shape of the lenses and the narrow field of view, the produced images were blurry and distorted. Of course Galileo’s telescope cannot be compared with today’s standard in optical technology. Because the design has no intermediary focus, the magnified picture results in a non inverted and upright image. For its design Galileo used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens. With a Galilean telescope, the observer could see magnified, upright images on the earth - it was what is commonly known as a terrestrial telescope or a spyglass. He later succeeded to improve the device significantly with up to about 30x magnification. However, t he actual inventor of the telescope is unknown but word of it spread through Europe. Based only on those rather uncertain descriptions of the first practical telescope which Dutch spectacle maker Hans Lippershey tried to patent in the Netherlands in 1608, Galileo, in the following year, was able to build a telescope with about 3x magnification. Among them was also his improvement of the telescope. Early Telescopesĭuring his time in Padua, Galileo made significant discoveries in both pure fundamental science as well as practical applied science. A year later already, he moved to the University of Padua, teaching geometry, mechanics, and astronomy until 1610. In 1586, Galileo made his first publication on the design of a hydrostatic balance he had invented ( Theoremata circa centrum gravitatis solidorum), which first brought him to the attention of the scholarly world and in 1589, he was appointed to the chair of mathematics in Pisa. He made his living with private lessons, studied applied mathematics, mechanics and hydraulics and began to attract attention in the educated circles of the city with lectures and manuscripts. As a consequence, he broke off his studies and went to Florence to study mathematics with Ostilio Ricci, a scholar from Nicolo Tartaglia’s school. He repeated this experiments with two pendulums at home which confirmed his observation. But soon after, the story goes that he was fascinated by observing a swinging chandelier, when he noticed that no matter how far it was swinging, it always took the same time swinging back and forth. Galilei was educated as a novice in the monastery of the Vallombrosans and was inclined to enter the Benedictine order, but was brought home by his father and sent to Pisa in 1580 to study medicine, where Galileo enrolled in 1581. Galileo Galilei came from an impoverished Florentine patrician family. Galileo Galilei Education and Early Career Galileo published his initial telescopic astronomical observations in March 1610 in a brief treatise entitled Sidereus Nuncius ( Starry Messenger). Besides its astronomical value Galileo‘s telescope was also a profitable sideline for him selling telescopes to merchants who found them useful both at sea and as items of trade. ![]() On August 25, 1609, Galileo Galilei publicly demonstrated his newly built telescope to Venetian lawmakers.
