Isaac Newton
Sir Isaac Newton PRS MP (/ˈnjuːtən/;[8] 25 December 1642 – 20 March 1726/7[1]) was an English physicist and mathematician (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus. Newton 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 of the visible spectrum. He formulated an empirical law of cooling, studied the speed of sound, and introduced the notion of a Newtonian fluid. Life Early life Isaac Newton (Bolton, Sarah K. Middle years Mathematics Optics

Isaac Newton Facts, Quotes, Gravity, Laws of Motion, Universal Gravitation Born in England, Isaac Newton was a highly influential physicist, astronomer, mathematician, philosopher, alchemist and theologian. In 1687, Newton published Philosophae Naturalis Principia Mathematica, what is widely regarded to be one of the important books in the history of science. In it he describes universal gravitation and the three laws of motion, concepts that remained at the forefront of science for centuries after. Newton’s law of universal gravitation describes the gravitational attraction between bodies with mass, the earth and moon for example. Newton’s three laws of motion relate the forces acting on a body to its motion. The first is the law of inertia, it states that ‘every object in motion will stay in motion until acted upon by an outside force’.

James Bradley James Bradley FRS (March 1693 – 13 July 1762) was an English astronomer and served as Astronomer Royal from 1742, succeeding Edmund Halley. He is best known for two fundamental discoveries in astronomy, the aberration of light (1725–1728), and the nutation of the Earth's axis (1728–1748). These discoveries were called "the most brilliant and useful of the century" by Jean Baptiste Joseph Delambre, historian of astronomy, mathematical astronomer and director of the Paris Observatory, in his history of astronomy in the 18th century (1821), because "It is to these two discoveries by Bradley that we owe the exactness of modern astronomy. .... This double service assures to their discoverer the most distinguished place (after Hipparchus and Kepler) above the greatest astronomers of all ages and all countries

Pharmacognosy Pharmacognosy is the study of medicines derived from natural sources. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical and biological properties of drugs, drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources."[1] It is also defined as the study of crude drugs. Introduction[edit] The word "pharmacognosy" is derived from the Greek words φάρμακον pharmakon (drug), and γνῶσις gnosis (knowledge).

Robert Hooke Robert Hooke FRS (/hʊk/; 28 July [O.S. 18 July] 1635 – 3 March 1703) was an English natural philosopher, architect and polymath. His adult life comprised three distinct periods: as a scientific inquirer lacking money; achieving great wealth and standing through his reputation for hard work and scrupulous honesty following the great fire of 1666, but eventually becoming ill and party to jealous intellectual disputes. These issues may have contributed to his relative historical obscurity. Robert Gunther's Early Science in Oxford, a history of science in Oxford during the Protectorate, Restoration and Age of Enlightenment, devotes five of its fourteen volumes to Hooke. Hooke studied at Wadham College during the Protectorate where he became one of a tightly knit group of ardent Royalists led by John Wilkins.

Pierre Bayle Pierre Bayle (French: [bɛl]; 18 November 1647 – 28 December 1706) was a French philosopher and writer best known for his seminal work the Historical and Critical Dictionary, published beginning in 1695. Bayle was a self-pronounced Protestant, and as a fideist he advocated a separation between the spheres of faith and reason, on the grounds of God being incomprehensible to man. As a forerunner of the Encyclopedists and an advocate of the principle of the toleration of divergent beliefs, his works subsequently influenced the development of the Enlightenment. Biography[edit] Ten Strange Facts About Newton Sir Isaac Newton (1642-1727) was the greatest scientist that ever lived. More than any other person, Newton was single-handedly responsible for laying the the groundwork in classical mechanics, optics, and even mathematics. Landing man on the moon?

Samuel Molyneux Samuel Molyneux FRS (16 July 1689 – 13 April 1728), son of William Molyneux, was an 18th-century member of the British parliament from Kew and an amateur astronomer whose work with James Bradley attempting to measure stellar parallax led to the discovery of the aberration of light. The aberration was the first definite evidence that the earth moved and that Copernicus and Kepler were correct.[1][2][3] In addition to his astronomical works, Molyneux wrote about the natural history and other features of Ireland.[3] Life[edit] Dream Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.[3] The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes.[3] People are more likely to remember the dream if they are awakened during the REM phase.

Leonhard Euler A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all."[6][7] Life[edit] Early years[edit] Baruch Spinoza Biography[edit] Family and community origins[edit] Spinoza's ancestors were of Sephardic Jewish descent, and were a part of the community of Portuguese Jews that had settled in the city of Amsterdam in the wake of the Alhambra Decree in Spain (1492) and the Portuguese Inquisition (1536), which had resulted in forced conversions and expulsions from the Iberian peninsula.[11] Attracted by the Decree of Toleration issued in 1579 by the Union of Utrecht, Portuguese "conversos" first sailed to Amsterdam in 1593 and promptly reconverted to Judaism.[12] In 1598 permission was granted to build a synagogue, and in 1615 an ordinance for the admission and government of the Jews was passed.[13] As a community of exiles, the Portuguese Jews of Amsterdam were highly proud of their identity.[13]

Charles-Augustin de Coulomb Charles-Augustin de Coulomb (French: [kulɔ̃]; 14 June 1736 – 23 August 1806) was a French physicist. He was best known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion, but also did important work on friction. The SI unit of electric charge, the coulomb, was named after him. Life[edit] Charles Augustin de Coulomb was born in Angoulême in France. His parents were Henry Coulomb and Catherine Bajet.
