**Isaac Newton**

**Sir Isaac Newton**PRS (4 January 1643 - 31 March 1727 OS: 25 December 1642 - 20 March 1727) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, and is considered by many scholars and members of the general public to be one of the most influential people in human history. His PhilosophiÃ¦ Naturalis Principia Mathematica (Latin for "Mathematical Principles of Natural Philosophy"; usually called the Principia), published in 1687, is one of the most important scientific books ever written. It lays 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.

**Newton**built the first practical reflecting telescope and developed a theory of color based on the observation that a prism decomposes white light into the many colours that 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 differential and integral calculus. He also demonstrated the generalised binomial theorem, developed

**Newton's**method for approximating the roots of a function, and contributed to the study of power series.

**Newton**was also highly religious. He was an unorthodox Christian, and during his lifetime actually wrote more on Biblical hermeneutics and occult studies than on science and mathematics, the subjects he is mainly associated with. (wikipedia)

**Isaac Newton**, as President of the Royal Society, did much to obscure Robert Hooke, including, it is said, destroying (or failing to preserve) the only known portrait of the man.Wikipedia, Robert Hooke

Isaac Newton, like Albert Einstein, is a quintessential symbol of the human intellect and its ability to decode the secrets of nature. Newton's fundamental contributions to science include the quantification of gravitational attraction, the discovery that white light is actually a mixture of immutable spectral colors, and the formulation of the calculus. Yet there is another, more mysterious side to Newton that is imperfectly known, a realm of activity that spanned some thirty years of his life, although he kept it largely hidden from his contemporaries and colleagues. We refer to Newton's involvement in the discipline of alchemy, or as it was often called in seventeenth-century England, "chymistry." Newton wrote and transcribed about a million words on the subject of alchemy. Newton's alchemical manuscripts include a rich and diverse set of document types, including laboratory notebooks, indices of alchemical substances, and Newton's transcriptions from other sources.
