Copernican revolution has a pivotal role in the establishment of the modern sciences. We are very much familiar with the fact that the human mind had always been fascinated greatly by the changes taking place around him almost constantly. Human observation and sense of argument and ability to be logical has made him the most intelligent and consequently most powerful species on the planet.
It is very comfortable to believe that Earth is located at the centre of the universe and other planets rotate around it because Earth itself does not seem or feel to be moving and there are only sun, moon and other planets appearing and disappearing at their exact timings. It is quite logical and unless and until something really revolutionary come forward to refute this believe, it looks quite reasonable to carry on believing the same idea (Kuhn, pp 187).
Nicholas Copernicus
The most significant change did happen at the reverse of this very well kept thought when Copernicus tried to alter the model proposed by Ptolemy, which had earth in the center. To prove his point he had to come up with some credible model that could potentially break the one strongly established before, which he unluckily failed to do. His proposal lacked reliability so was excessively ridiculed by his contemporaries.
Galileo
A noticeable transformation in the domain of science occurred when Galileo came forward with properly defined answers to the idea of putting sun in the center and proposing the continuous motion of earth around it. As known by many, a moving object comes to a stop eventually after moving for some time which is due to friction. To keep a moving object carry on its motion, a constant pushing force has to be applied on it. This idea was sounded as reasonable to the philosophers of that time as the idea of moving sun and moon. This proposed outline was plausible. He further added that with this having in mind, in the absence of friction, the object will carry on its regular...
