He also devised a type of simple thermometer.

What did galileo do

Galileo then began to prepare himself to teach Aristotelian philosophy and mathematics, and several of his lectures have survived. He understood the parabola , both in terms of conic sections and in terms of the ordinate y varying as the square of the abscissa x. Galileo discovered four of Jupiter's moons almost four hundred years ago. Furthermore, the realization that the surface of the moon is rough disproved the Aristotelian view of a perfect, immutable celestial realm. He began to study medicine at the University of Pisa but changed to philosophy and mathematics. Because of his age and poor health, he was allowed to serve his imprisonment under house arrest. The youngest, Michelangelo or Michelagnolo , also became a noted lutenist and composer although he contributed to financial burdens during Galileo's young adulthood. Galileo published a full description in Sidereus Nuncius in March The phases of Venus , observed by Galileo in Based only on uncertain descriptions of the first practical telescope which Hans Lippershey tried to patent in the Netherlands in , [] Galileo, in the following year, made a telescope with about 3x magnification. Michelangelo was unable to contribute his fair share of their father's promised dowries to their brothers-in-law, who would later attempt to seek legal remedies for payments due. These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income.

Thomas Harriot, who also directed the telescope at the moon and discovered the laws of gravity, is considered an English Galileo. This was one of the secrets of his success: He was part of a broad, cosmopolitan culture that was equally interested in science, art and literature; a culture, for which the philosophical questions concerning the nature of world were closely related to scientific and practical problems.

Galileo obeyed the order for seven years, partly to make life easier and partly because he was a devoted Catholic.

Galileo also studied disegno, a term encompassing fine art, and, inobtained the position of instructor in the Accademia delle Arti del Disegno in Florence, teaching perspective and chiaroscuro. Because of his age and poor health, he was allowed to serve his imprisonment under house arrest.

After Galileo began publishing papers about his astronomy discoveries and his belief in a heliocentricor Sun-centered, Universe, he was called to Rome to answer charges brought against him by the Inquisition the legal body of the Catholic Church.

He subsequently used his newly invented telescope to discover four of the moons circling Jupiter, to study Saturn, to observe the phases of Venus, and to study sunspots on the Sun. Inside the thermoscope, a liquid rises and falls in a glass tube as the temperature of the liquid rises or falls. When Galileo Galilei was eight, his family moved to Florence , but he was left with Jacopo Borghini for two years. A Question. Galileo's observations discredited the Aristotelian theory of an Earth-centered solar system in favor of the Copernican heliocentric model. Barberini was a friend and admirer of Galileo, and had opposed the condemnation of Galileo in The earliest known written account of the legend dates to a century after his death, but Stillman Drake writes "there is no doubt now that the famous words were already attributed to Galileo before his death". He went completely blind in and was suffering from a painful hernia and insomnia , so he was permitted to travel to Florence for medical advice.

Vincenzo decided that his son should become a doctor. With his lectures, Galileo followed this tradition of literary-scientific popular education. Science can stand for enlightenment and emancipation; however, it can also be used in the interest of power.

Inhe moved to the University of Padua where he taught geometry, mechanicsand astronomy until His works are correspondingly multi-faceted.

When Galileo Galilei was eight, his family moved to Florencebut he was left with Jacopo Borghini for two years. In his day, these occupations were not as strictly separated as they are today.

However, he was eventually persuaded to admit that, contrary to his true intention, a reader of his Dialogue could well have obtained the impression that it was intended to be a defence of Copernicanism.
