ISAAC NEWTON

 

Isaac Newton was born on January 4, 1643 at Woolsthorpe Manor, United Kingdom. Sir Isaac Newton was a follower of the heliocentric school and a scientist who was very influential throughout history and is even said to be the father of classical physics whose knowledge can be enjoyed until now. Isaac Newton is also very popular with the discovery of Newton's Law and the Earth's Gravity Force which is also the beginning of Isaac Newton's biography until it is known to the world.

Isaac Newton had a book Philosophiae Naturalis Principia Mathematica which was published in 1687 and is considered the most influential book in the history of Science. This book lays the foundations of classical mechanics. In this work, Newton outlined the earth's law of gravity and three laws of motion that dominated scientific view of the universe for three centuries. In this book Newton also succeeded in showing that the motion of objects on earth and other celestial bodies is governed by the same set of natural laws. He proved this by demonstrating a consistency between Kepler's laws of planetary motion and his theory of gravity. This work ultimately cleared scientists' doubts about heliocentrism and promoted a scientific revolution at that time.

As for the field of mechanics, Newton also sparked the existence of a principle of conservation of momentum and angles. In the field of optics, Newton built the first reflecting telescope by trying to develop a color theory on the basis of the observation that a glass prism will divide white light into other colors. He also formulated the law of cooling and studied the theory of the speed of sound.

And in the field of mathematics too, together with the work of Gottfried Leibniz which was carried out separately then Newton tried to develop differential calculus and integral calculus. Newton succeeded in elaborating the binomial theory, developing the "method of Newton's laws" to make efforts to approach the zero value of a function and make contributions to the study of power series. Among scientists, until recently Newton was very influential. Even Isaac Newton's biography is highly sought after. A 2005 survey that asked scientists and the general public in the Royal Society about who contributed to science whether Newton or Albert Einstein, most of them indicated that Newton's influence was much greater.
