While at Pisa, Galileo was exposed to the Aristotelian view of the world, then the leading scientific authority and the only one sanctioned by the Roman Catholic Church. At first, Galileo supported this view, like any other intellectual of his time, and was on track to be a university professor. However, due to financial difficulties, Galileo left the university in before earning his degree.

Galileo continued to study mathematics after leaving the university, supporting himself with minor teaching positions. During this time he began his two-decade study on objects in motion and published The Little Balancedescribing the hydrostatic principles of weighing small quantities, which brought him some fame. This gained him a teaching post at the University of Pisa, in While there, Galileo conducted his fabled experiments with falling objects and produced his manuscript Du Motu On Motiona departure from Aristotelian views about motion and falling objects.

Galileo developed an arrogance about his work, and his strident criticisms of Aristotle left him isolated among his colleagues. Inhis contract with the University of Pisa was not renewed. Galileo quickly found a new position at the University of Paduateaching geometry, mechanics and astronomy. The appointment was fortunate, for his father had died inleaving Galileo entrusted with the care of his younger brother.

During his year tenure at Padua, he gave entertaining lectures and attracted large crowds of followers, further increasing his fame and his sense of mission. InGalileo met Marina Gamba, a Venetian navipedia galileo biography, who bore him three children out of wedlock: daughters Virginia and Livia, and son Vincenzo. He never married Marina, possibly due to financial worries and possibly fearing his illegitimate children would threaten his social standing.

Galileo worried his daughters would never marry well, and when they were older, had them enter a convent. Maria Celeste remained in contact and supported her father through letters until her death. No letters from Arcangela survive. In JulyGalileo learned about a simple telescope built by Dutch eyeglass makers and soon developed one of his own.

Galileo transmits several signals and codes on four different carrier frequencies within the 1. Following image shows the Galileo Signal Frequencies. See further details on Galileo Signal Plan article.

He quickly improved his telescope, and according to his own words, "built an instrument so perfect that objects appeared almost a thousand times larger and more than thirty times closer than when observed with the naked eye". Galileo turned his telescope towards the sky on the night of January 7, What he saw there — the lunar landscape, mountain ranges and peaks — led him to believe that the Moon resembled the Earth and had mountain systems.

This discovery contradicted religious dogma and Aristotle's teachings about the special position of Earth among celestial bodies. Galileo also discovered four moons of Jupiter, which also contradicted Aristotle's teachings. He established that the Sun rotates on its axis. Based on his observations, Galileo concluded that rotational motion was inherent to all celestial bodies and that the heliocentric system proposed by Copernicus was the only true one.

Galileo began to advocate more boldly for Copernican theory. Ineleven prominent theologians reviewed Copernican theory and concluded that it was false. Galileo was summoned from Florence to Rome and ordered to cease propagating heretical views on the structure of the universe. Galileo was forced to comply. The book was written in the form of a dialogue between two Copernican supporters and one adherent of Aristotle and Ptolemy.
