What some may not know is that he made major breakthroughs in these areas while practicing social distancing during the Great Plague that spread in England in 1665. He is famous for his discoveries in the fields of motion, gravity, optics, and mathematics. Sir Isaac Newton (January 4, 1643-March 31, 1727) was an English physicist and mathematician. However, Isaac Newton proves that time spent in social isolation can lead to great insights. Without our normal routine, it might feel like we are not accomplishing much. They did then, they do now… and they will… a billion years from now.As we are practicing social distancing during this time, it is easy to feel restless. ![]() Whether or not he could explain what exactly gravity was, Newton’s laws of motion worked. So how is it that say, the Sun is affecting the motion of the Earth. There’s no rope between them, there’s no hand reaching out from one to the other. He himself was troubled by the fact that he didn’t know how the influence was traveling from one object to another. But what it doesn’t do, what Newton never did was explain what gravity actually was. Newton saw gravity like a tether invisibly connecting objects. In his great book the Principia, he uses observation and mathematical formulai to predict the orderly phenomena of nature, including gravity. Newtown’s laws were a fundamental language of the Universe.Īnd so, physics really began with Isaac Newton. Newtown’s laws have explained almost everything. So Newton showed that even the Universe is subject to the same law that makes an apple fall. The moon is in freefall around the Earth. The same forces that govern an apple, govern the Moon. Then, in a flash of insight, Newton realized that the Moon is falling around the Earth. And then he asked the key question: “If an apple falls to the Earth, does the Moon also fall?” This revolutionary insight reportedly occurred to Newton during an innocent stroll through his estate in the evening. The great insight Newton had was to bring Galileo and Kepler together and to realize that the things that make projectiles move and fall at the same speed here on Earth, is the same thing that makes planets go around the sun in the skies. Galileo had demonstrated that on earth, falling bodies that no matter what their mass, always fall at the same rate. ![]() They sped up the closer they came to the sun.
