Sir [[Isaac Newton]] was an English [[scientist]] who lived from 1634 to 1727.  He was a physicist, astronomer, mathematician, alchemist and natural philosopher.  He is probably best known for his Theory of Universal Gravitation and his Laws of Motion.  His contributions also include inventing the reflecting telescope, developing calculus (apparently before [[Gottfried Leibniz]], though he published his work on calculus after Leibniz<ref>Newton Biography[http://scienceworld.wolfram.com/biography/Newton.html]</ref>), and numerous other contributions to his fields of study.

Newton was the first to demonstrate that the same laws that govern the motion of celestial objects also govern the motion of things on Earth.  Newton's contributions greatly advanced the scientific revolution.  His work also advanced the concept of heliocentrism (the belief that the Sun is at the centre of the Solar System and/or Universe), with his works prompting the lifting of a ban on heliocentric books by the Catholic Church.
