Sir Isaac Newton - - Born January 4, 1643 in Lincolnshire England, died March 31, 1727 in England He was schooled at Cambridge Is considered possibly one of the greatest scientists who ever lived He described universal gravitation through his three laws of motion He invented the first reflecting telescope In the field of mathematics he helped create calculus as well as contributing to the study of the power series His work on universal gravitation has been set in stone and it still used today in modern astronomy All his work was and still is being accepted by the world as correct and effective in the field of math and science His work has paved the way for further scientists to make more discoveries and continue to make breakthroughs His three laws of motion: 1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. 2. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. 3. For every action there is an equal and opposite reaction. Calculus is a widely used math that can be utilized for many different purposes the Reflective telescope has been modified and transformed into a machine that can see planets and stars from unimaginable distances.
