The Catholic Church sentenced Galileo to house arrest for the remainder of his life, but his ideas of a heliocentric universe remained strong. This idea changed man's whole view of his significance and place in the universe. Now, man was no longer the center of everything. Man was not as important as he originally thought. This also meant that the Church was not preaching the truth, and that the Bible and Aristotle were wrong. This raised questions about the validity of the rest of the Bible and Aristotle's teachings. .
During the Scientific Revolution, scientists developed ways to make more precise, and more reliable observations. The new scientists challenged the assumptions of past scientists. Zacharias Janssen invented the first microscope. Anton van Leuwenhoek used a microscope to observe bacterium and red blood cells. Galileo made the first thermometer using alcohol for measuring temperatures. Later, a German physicist named Gabriel Fahrenheit developed the first thermometer using mercury. In 1655, Evangelista Torricelli developed the barometer. The barometer measured atmospheric pressure. The barometer proved that the weather could be predicted, and therefore God did not control the weather. This new information disturbed the Catholic Church. Again, they were caught preaching the wrong information. Galileo proved Aristotle wrong when he rolled balls down a slope, measuring.
the speed at which they moved. This data led him to the conclusion that a falling object accelerates at a fixed and predictable rate. Aristotle stated that a falling object accelerated in accordance with its mass, again Aristotle was proved wrong. These new discoveries disturbed man, and the way in which he viewed and understood nature. New scientists and their experiments were disproving everything that man had previously known to be true. .
Andreas Vesalius did not accept the Roman Galen's authority of human anatomy since it was based on animal dissections.
