During the Renaissance there was a spirit or time of questioning when people wanted to know more about their world. Galileo was called the "Father of Modern Science" because he tried to prove all this theories about the universe scientifically. Galileo originally studied medicine but did not finish. Galileo instead studied maths and developed a theory by which all objects fall at the same speed which he called "The Theory of Falling Bodies". He put this theory into practice when he dropped a feather and an apple from the leaning tower of pisa. He improved the recently developed telescope by Copernicous to allow him to study the stars.He also single-handedly developed the compass and thermometer. This study of astronomy convinced him that the Polish astonomer Copernicus was right in saying the sun was at the center of the universe and that the Earth revolves around it. This went against the beliefs and teachings of the church and Galileo was placed under house arrest for heresy. In time Galileos ideas were accepted by everyone.
