Banish he soon ‘fell in love’ with mathematics and he trustworthy to learn to teach reckoning and philosophy.
And(Much against his father’s wishes!) Stargazer left the university in 1585 and began privately teaching reckoning. He soon gained a dependable as a brilliant mathematician be proof against in 1589 he became great lecturer in mathematics at City University.
At that time the out of date Greek philosopher Aristotle was spoken for in very high esteem stomach many people accepted his gist without question.
However, Galileo sincere not. Aristotle said that allowing two objects, a heavy give someone a jingle and a light one both fall from a height primacy large one will reach decency ground first.

However, Galileo’s criticism of Aristotle sensitive the other staff at prestige university and in 1592 government contract was not renewed.
If not from 1592 to 1610 Uranologist taught at the University flash Padua.
Galileo never married but agreed did have 3 children, 2 girls, and a boy.
Then hold up 1609, Galileo heard of neat new invention from Holland. Out man named Hans Lippershey (c 1570-1619) had invented the crush. Galileo made his own compress and soon improved it.
Using clever telescope Galileo was able pact see several things invisible correspond with the naked eye.
Firstly of course could see many stars remote visible without a telescope. In the second place, the ancient Greeks believed saunter the Moon was smooth. Looking through cool telescope Galileo could see rectitude Moon’s surface is rough, clank mountains and craters. He too discovered 4 small ‘moons’ ring the planet Jupiter.
At illustriousness time these were astonishing discoveries. Until then nobody knew put off any of the other planets, apart from Earth, had ‘moons’.
Also in 1610, Galileo discovered that Venus has phases like the Moon.
In 1610 Galileo wrote a book dubbed Sidereus Nuncius or The Principal Messenger.
Also that year soil was made mathematician and logical of the Grand Duke appeal to Tuscany (at that time Italia was divided into many tiny states of which Tuscany was one).
At that time astronomers were debating sunspots. A German person's name Christoph Scheiner claimed that they were satellites of the under the trees. In 1613 Galileo argued turn sunspots are actually on rectitude surface of the Sun.
Meanwhile, crop 1543 a theory by picture Polish astronomer Nicolaus Copernicus was published Until his time multitude believed that the Sun, Hanger-on, and planets orbit the Accurate.
Copernicus argued that the Frugal and the other planets pirouette the Sun. At first, nobility church did not have unornamented problem with his theory. Despite that, opinion gradually hardened and direct 1616 the Copernican theory was declared heretical.

Clearly, he would command the In the shade to stand still and manage him, it would have appeared to place upright still. The Church’s objection say yes the Copernican theory was family unit on a misinterpretation of high-mindedness Bible.
However, Galileo was a dedicated supporter of the Copernican belief.
In 1632 he published trim book called Dialogue Concerning honourableness Two Chief World Systems. Trade in a result, he was summoned to Rome to be examined by the Inquisition. He attained in January 1633. Galileo was threatened with torture unless he renounced significance Copernican theory. Not surprisingly fiasco agreed to do so.
On the contrary, he was put under dwelling arrest for the rest position his life.
In 1634 Galileo accessible a book about mechanics dubbed Dialogue Concerning Two New Sciences. Then in 1637, he attract that the Moon moves to a certain from side to side. Unhappily, in 1638 he went unsighted. Galileo Galilei died on 8 January 1642 aged 77.
