Sistema heliocentrico de Galileu

When Galileo published his book debating the Copernican and Ptolemaic systems, the Church found him guilty of heresy and sentenced him to house arrest for the rest of his life. Today, Galileo is recognized for his revolutionary work in both astronomy and physics, and has been referred to as "the father of modern science." In addition to his findings in support of the Copernican system, his theories regarding falling objects and objects in motion laid the groundwork for classical mechanics. He was also a pioneer in the approach we call the scientific method, which utilizes observation and experiment. In 1992, three hundred and fifty years after his death, the Church officially apologized for condemning Galileo and his scientific research.
