Galileo Galilei in the Scientific Revolution
What would Physics and Astronomy be like today if Galileo Galilei never existed? Although it is taken for granted that the scientific revolution occurred and changed a lot of things in the sixteenth and seventeenth century, it pioneered all of the scientific improvements that stand in place today. However, even to present day, some scientist such as Steven Shapin argue that there was no such thing as the scientific revolution and that it was just a natural continuation of progress that was already going on in Europe and Islam during the Middle Ages.
Galileo Galilei was born in Italy in 1564 and played a key role in the scientific revolution. …show more content…
In 1610, he published a 24-page booklet called The Starry Messenger. Here he described that the surface of the moon is rough rather than smooth, proved the existence of many more distant stars than were currently known, and went into detail about how he saw the planets through his telescope that appeared as circular globes. Also in his book, Galileo wrote about the moons of Jupiter and Venus’s phases like those of the moon, and the dark spots on the sun. A few years later in his career, Galileo began to have some conflicts with the Church. In 1612, he announced that the sun itself was revolving after all of his work and observations of dark spots on the sun. These theories were contrary to the Church doctrine and the Inquisition asked him to abandon his opinions. By 1630 Galileo had completed the Dialogue on the Two Chief Systems of the World, this is where he compared the Ptolemaic, or geocentric and the Copernican, or heliocentric systems, and found the heliocentric model far superior. In this work, he went into lengthy detail about the doctrine of uniformity where he states that any cause corresponds to an affect throughout the universe. Those theories then led to terrestrial physics and how it could be used to explain the motion of heavenly bodies. The Church was not in favor of those theories either, in turn causing Galileo to be put on house arrest for the rest of his life after being found guilty of heresy. Galileo was forced to sign a recantation of his theories and the sale of his book was
