Final answer:
The work "Discourse on Method" is not authored by Newton; it was written by René Descartes. Newton's major works include "Opticks" and "Philosophiae Naturalis Principia Mathematica" (the Principia), which established the foundation for classical mechanics.
Step-by-step explanation:
Among the options provided, "Discourse on Method" is not authored by Sir Isaac Newton.
This work was written by René Descartes and is a foundational text of modern philosophy, not Newton's works on motion, gravity, and the scientific method.
Instead, Newton's significant contributions include his works titled "Opticks", where he discussed the theory of light and color, and the "Philosophiae Naturalis Principia Mathematica", commonly referred to as the "Principia", published in 1687. In the "Principia", Newton laid the foundation for classical mechanics with his three laws of motion and his law of universal gravitation.
These works by Newton are still revered today for their impact on physics and natural science.
