# What Are Isaac Newton's Scientific Achievements?

**Isaac Newton’s scientific achievements include his three laws of motion — inertia, acceleration, and action and reaction the law of universal gravitation, the reflecting telescope and the theory of calculus.** Newton published important written works, the most famous of which is “Principia Mathematica,” where he described elliptical orbits, forces in motion, fluids and mechanics.

PBS suggests that Isaac Newton became the father of modern science because he invented many elements of the modern scientific method, which governs how all science is conducted today. Newton proposed many theories on light and color, such as all colors blending into whiteness, in his publication, "Opticks." His secret practice of alchemy, where he experimented with various metals, formed the basis for modern chemistry.

According to TheFamousPeople, Sir Isaac Newton is considered to be the greatest and most influential scientist who ever lived, as well as one of the paramount contributors of the 17th century scientific revolution. HowStuffWorks describes Newton’s quest for the philosopher’s stone with his experiments in alchemy. This was a man-made stone capable of universal transmutation, which was never fully realized by the scientist. Newton’s written mathematics theories, called the science of fluxions, were conceived to use as calculations for his scientific experiments and later became the basis of calculus.
