The importance of scientific experiments
The emerging of modern science could be traced back to the era of Roger Bacon who was an outstanding monk and philosopher in Oxford. He was born in 1214 and died in 1292. With many extraordinary findings by himself, he might be the first in the Middle Ages to bring up the thought that science must be explored through observing and experimenting on the surroundings. Galileo, however, born 300 years later, was the greatest among several great persons in Italy, France, Germany and England who convinced the public in steps that many important truths could be discovered via appropriate observations. Before Galileo，the scholars believed without any doubt that larger objects fell to the ground at a faster rate than the smaller ones just because Aristotle said so. However, from the top of the Leaning Tower of Pisa, Galilleo dropped two stones of distinctively different sizes which landed on the ground at exactly the same time, and thereby, testified that Aristotle was wrong, to his friends who witnessed this experiment. It is Galileo’s spirit of experimenting directly in nature to verify our judgments and theories that has brought the modern science to fruition in all great discoveries.
