The life and beliefs of galileo galilei

We know this from drawings in his notebook. Discovered that Venus has phases like the moon, ranging from a thin crescent to full. Anyway, Galileo, working with a physician friend Santorio, constructed a simple device, which became known as a pulsilogia, and became widely used.

He was the first to see craters on the moon, he discovered sunspots, and he tracked the phases of Venus. For Copernicanism and for the ChurchThe life and beliefs of galileo galilei.

He was not, in fact, confined to jail at all, but merely to house arrest in his own comfortable villa in Arcetri. He wrote a letter of apology after being reproved. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it.

Galileo Galilei

Publication of Il saggiatore came at an auspicious moment, for Maffeo Cardinal Barberini —a friend, admirer, and patron of Galileo for a decade, was named Pope Urban VIII as the book was going to press.

Galileo was ordered to read the seven penitential psalms once a week for the next three years. In other words, he took a practical rather than a theoretical approach to music: Discovered that for pendulums, their period of oscillation squared is directly proportional to their length and is independent of the mass attached to the string or rod.

Showed that the set of perfect squares 1, 4, 9, 16, 25, 36, 49, 64, 81, … has as many members in it as the set of whole numbers 1, 2, 3, 4, 5, 6, 7, 8 9, 10… even though, at first sight, the set of whole numbers appears to contain more members.

Tried to measure the speed of light, but found it was too fast for him to measure. Prompted by this incident, Galileo wrote a letter to Castelli in which he argued that heliocentrism was actually not contrary to biblical texts, and that the bible was an authority on faith and morals, not on science.

Why should all the water on the surface of the earth slosh around once or twice a day? Galileo worked on his new book, which he intended to call "Dialogue on the Tides", from to He rejected the notion that scientific questions could be decided by reliance upon authority, whether it be the pronouncements of the Church of the assertions of Aristotle.

Near the end of his lifetime, Galileo designed the first pendulum clock. In Italian scientist Galileo Galilei, using his own telescope, modeled on an invention recently made in the Netherlands, discovered that the Moon, far from being smooth and utterly unlike Earth, had mountains and craters.

Galileo was not too upset at the thought of a trial, because he held a trump card: Discovered the first moons ever known to orbit a planet other than Earth. On 25 Augusthe demonstrated one of his early telescopes, with a magnification of about 8 or 9, to Venetian lawmakers.

The rings of Saturn puzzled him, appearing as lobes and vanishing when they were edge-on — but he saw them, which was more than can be said of his contemporaries. Galileo discovered that the Milky Way is made up of stars.

Here he summarised work he had done some forty years earlier, on the two sciences now called kinematics and strength of materialspublished in Holland to avoid the censor.

Although these discoveries did not prove that Earth is a planet orbiting the Sunthey undermined Aristotelian cosmology: SinceGalileo had been observing the motion of sunspots: The lectures went over very well, and he got the job. His telescopes were also a profitable sideline for Galileo, who sold them to merchants who found them useful both at sea and as items of trade.

Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter, now known as the Galilean moons: Galileo watched the swinging lit lamp for some time.

Take note, theologians, that in your desire to make matters of faith out of propositions relating to the fixity of sun and earth, you run the risk of eventually having to condemn as heretics those who would declare the earth to stand still and the sun to change position-eventually, I say, at such a time as it might be physically or logically proved that the earth moves and the sun stands still.

Galileo also became a skilled lute player. In order to perform his experiments, Galileo had to set up standards of length and time, so that measurements made on different days and in different laboratories could be compared in a reproducible fashion. For example, it was okay to pretend that the earth orbited the sun to help with astronomical calculations, but it was not okay to state that it was true that the earth orbited the sun.

Discovered the rings of Saturn, although he found their appearance very confusing.Galileo Galilei was an Italian physicist and was born in Pisa on February 15, Galileo's father, Vincenzo Galilei, was a well-known musician.

Vincenzo decided that his son should become a doctor.

Actually, Vincenzio was a revolutionary musician—he felt the formal church music that then dominated the scene had become sterile, and that classic Greek poetry and myths had a power the church music lacked.
