It seemed to him that the lamp was taking the same length of time to swing a short distance as a long one. He swung it again, determined to make sure. But he had no watch with which to test it, and so he put his fingers on his pulse and counted the beats. When the lamp was nearly still it took as long to do its little swing as it had taken to do its big one. Galileo had made a discovery. He had found that the length of time it takes a weight on a string to swing does not depend on the distance it swings, but on the length of its chain or cord.
One day he found that a heavy weight and a light one would both fall to the ground at the same moment. When no one would believe him, he said, "Very well, I'll prove it. Meet me in the square by the Leaning Tower.
Eager young students, grey-bearded professors, and all sorts of people from the town came to the square, shrugging their shoulders and saying, "What nonsense. Well, it will do him good to make a fool of himself. He climbed the stairs of the famous Leaning Tower of Pisa and stood looking down at the crowd. On the edge of the tower, he placed two cannon balls. One weighed a hundred pounds and the other, one pound.
Just at that moment Galileo pushed the balls over the edge. Sure enough, he proved all of them wrong. They struck the ground at the same moment. The old books, which the professors had believed without trying to prove, were quite wrong. Meanwhile, Galileo had read about Copernicus, who had watched the stars and planets and had seen that they were in different parts of the sky at different times.
He came to the conclusion that the sun was the centre of all movement and not the earth. The earth is a planet like Jupiter or Venus. Galileo believed in Copernicus, though the whole world laughed, and decided to find out the movements of the planets. It would help to prove that Copernicus was right.
He set to work, but none of his experiments were of any use until, one day, he picked up a bit of old organ pipe and, pushing a bulgy spectacle glass into one end and a hollow one into the other, he looked through it. For a minute he said nothing; then his face lit up with a wonderful smile. His queer new instrument had made things look three times nearer and not upside down.
The Starry Messenger was well-received, but a later, more candid discussion of Copernicanism, published in as Historia e dimonstrazioni intorno alle macchie solari Sunspot Letters was condemned by the Church as an outspoken defense of heliocentrism.
After it was written, however, the Pontiff criticized the Dialogue for two reasons: Events happened fairly quickly after that: In February of , the Dialogue was published; in October of that same year, Galileo was ordered to come to Rome to answer before the Inquisition. In June of , Galileo was compelled to repudiate the Dialogue on his knees before his accusers.
He was sentenced as a heretic and condemned to imprisonment for life—a sentence that was softened to house arrest with the understanding that Galileo would never again publish his writings. When he died in , he was blind but still publishing—although outside Italy. To the end of his life, Galileo insisted that there was no conflict between Copernicanism and his own devotion to the Church.
Galileo's major works include The Starry Messenger , which generated much positive excitement when it focused people's eyes for the first time on what was actually happening in the sky. His Sunspot Letters , on the other hand, are notorious. As Stillman Drake points out, Galileo wrote these Letters in Italian rather than in Latin a scholarly and liturgical language that was universal only to those who were educated ; by contrast, the colloquial Letters were accessible to "practically everyone in Italy who could read.
Galileo's most famous work, the Dialogue Concerning the Two Chief World Systems , is well-known not for its rigid defense of the Copernican against the Ptolemaic system for it was meant to consider the two impartially ; instead, it is infamous because Galileo wrote it after he had apparently been forbidden to write or teach anything at all about the Copernican system.
Thus the Dialogue was catalyst for Galileo's appearance and conviction before the Inquisition. Yet he does so while trying to prove that heliocentrism and the interpretation of the Bible are not at odds.
Thus, it has "become a classic in literature relating to the conflict between science and religion," and "passages [from it] are often quoted for the sheer power of their expression and the acuity of their observations.
Today, experts on the life and works of Galileo are increasingly coming to believe that he was a victim not of his ideas, but of politics. Several scholars have called into question the very existence of the document of in which Galileo was supposed to have promised never to teach or write about the Copernican system.
