Here in this paper, both are discussed. compared and analyzed in a deep manner as per their respective works which brought about a significant change within our modern day luxuries that mankind has in the present times.Galileo was born on 15th February 1564 and is widely regarded as an Italian physicist, astronomer, mathematician and philosopher of repute. He had a major hand in bringing about the scientific revolution within history. His name is synonymous with the very best in the world of innovators, physicists and thinkers since he was, is and will always remain a genius. Mankind owes a lot of gratitude to the personality of Galileo and hence the reason that he is still remembered as a hero notwithstanding a great amount of time has passed since he died – on 8th January 1642. Galileo brought to the fore his achievements in the line of improvements that he made towards the working domains of the telescope as well as the consequent astronomical observations with added support for the sake of Copernicanism. Without a doubt, this formed the basis as to why he was regarded as the father of modern observational astronomy, the father of modern physics, the father of Modern Science and the father of science. Galileo studied the motion of uniformly accelerated objects which is usually there in all school and college curricula. The physics courses have special mention of such objects and it comes especially under the heading of kinematics. Galileo made contributions towards the field of observational astronomy which has entailed within it the discovery of the four largest satellites that Jupiter has and named as the Galilean moons. This was so done to give him honor and respect for his work. He also studied the sunspots, firstly made an observation regarding them and then analyzing them in the end. Further, he worked tirelessly towards the related fields of applied science and technology. (Shea amp. Artigas, 2003)On the other hand, Sir
