Notes & Condition: Isaac Newton's genius scientific theories
reached heightened interest approximately two hundred years after his death,
according to this essayist, who compares the scientist's work with gravity
and mechanics to modern science. Following the release of two volumes in 1934,
'Isaac Newton: A Biography,' by Louis Trenchard More, as well as
'Newton and the Origin of Colours,' by Michael Roberts and E.R. Thomas,
the author of this succinct essay critiques these volumes, inlcuded elements
which were omitted.

Sir Isaac Newton(1643-1727) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian and one of the most influential men in human history. His Philosophiæ Naturalis Principia Mathematica, published in 1687, is considered to be the most influential book in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the scientific revolution.
In mechanics, Newton enunciated the principles of conservation of both momentum and angular momentum. In optics, he built the first practical reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into the many colours which form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound.
In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. He also demonstrated the generalised binomial theorem, developed the so-called "Newton's method" for approximating the zeroes of a function, and contributed to the study of power series.
