Issac Newton and Paving the Way for Modern Physics Essay
Issac Newton and Paving the Way for Modern Physics - Essay Example It is thus no exaggeration to say that Newton paved the way for Modern Physics. The rest of this essay will flesh out this claim. Although retrospectively, Isaac NewtonÃ¢â¬â¢s genius and legacy are now accepted facts, there was no inkling during his early years that this was destined him. Born in Woolsthorpe, England on a Christmas Day in 1642, there were odds stacked against NewtonÃ¢â¬â¢s survival. He was born premature and his survival was uncertain. Just prior to his birth his father had expired. Even his youth was nothing illustrious, as he even ventured briefly into managing his family farm. The turning point for NewtonÃ¢â¬â¢s life in science came with his enrolment in Cambridge University in 1661. Here, he came under the charge of distinguished cleric and mathematician Isaac Barrow, who mentored and inspired the young man, especially in mathematics. It was under the guidance of Barrow that Newton would conceive and articulate some of the most groundbreaking scientific dis coveries of the modern era.i As per an autobiographical account written for his nephews, the major streams of Newton's scientific work were all initiated during the plague years of 1665--66, when Cambridge was closed down due to an outbreak of plague and the young Newton went home for a short break. It was during this time that some of the cornerstone discoveries and inventions of modern physics came about. During this period, the inquisitive and penetrative mind of Newton started working on the laws of universal gravitation, the development of calculus, and the nature and behavior of light. The findings he made on these projects would enable him to make vital contributions to mathematics, theoretical physics, astronomy and experimental physics. Given the magnitude of some of these contributions, it is fair to say that Newton opened new vistas in these subjects and spawned the development of modern physics. In other words, he began to invent Ã¢â¬Å"a set of mathematical techniques, including what we call the binomial theorem and differential calculus. He did a set of optical experiments that demonstrated that white light is composed of a mixture of all colors of the rainbow. And he theorized that the Moon is maintained in its orbit around Earth by the same force that causes heavy objects near Earth's surface to fall to the ground--in other words, he began to think about the law of universal gravitation.Ã¢â¬ ii Although there is no precise answer to the date of origin of modern physics, a strong case can be made that it started in 1647 with the publication of Isaac NewtonÃ¢â¬â¢s Philosophie Naturalis Principia Mathematica. In recognition of the momentousness of this publication, the Encyclopedia Britannica called Newton Ã¢â¬Å"Ã¢â¬â¢the culminating figure of the scientific revolution of the l7th CenturyÃ¢â¬â¢, and describes Principia Mathematica as Ã¢â¬Ëone of the most important works in the history of modern science.Ã¢â¬â¢ From its inception, modem science has quite simply dominated the human mind.Ã¢â¬ iii The sweep and influence of NewtonÃ¢â¬â¢s work on subsequent scientific developments can be gleaned from the list of his important works. In Philosophiae Naturalis Principia Mathematica, Newton gives a concise account of his discoveries in terrestrial and celestial mechanics, which is a cornerstone for modern physics. In it, he explicated how universal gravitation is operant upon objects on earth as well as in the celestial space. Further, Ã¢â¬Å"
