Isaac Newton held Galileo Galilei in high regard and greatly admired his scientific contributions. Newton considered Galileo as one of the pioneers of the scientific method and credited him for laying the foundation of modern physics through his experimental approach and mathematical descriptions of motion.
Galileo's scientific conclusions, particularly his work on motion and mechanics, were instrumental in shaping Newton's own understanding of the subject. Newton built upon Galileo's ideas and expanded them with his laws of motion and the theory of universal gravitation, which formed the basis of classical mechanics.
Newton famously wrote, "If I have seen further, it is by standing on the shoulders of giants," referring to Galileo and other eminent scientists whose work he respected and built upon. Newton's Principia Mathematica, published in 1687, was heavily influenced by Galileo's principles and observations.
In summary, Newton held Galileo in high esteem and considered his scientific conclusions as significant contributions to the field of physics. Newton's own work built upon and extended the ideas and principles established by Galileo.
