Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1726) 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.<br/><br/>

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.

Philosophiæ Naturalis Principia Mathematica, Latin for 'Mathematical Principles of Natural Philosophy', often referred to as simply the Principia, is a work in three books by Sir Isaac Newton, in Latin, first published 5 July 1687.<br/><br/>

After annotating and correcting his personal copy of the first edition, Newton also published two further editions, in 1713 and 1726. The Principia states Newton's laws of motion, forming the foundation of classical mechanics, also Newton's law of universal gravitation, and a derivation of Kepler's laws of planetary motion (which Kepler first obtained empirically).<br/><br/>

The Principia is 'justly regarded as one of the most important works in the history of science'.

Francois-Marie Arouet (21 November 1694 - 30 May 1778), more commonly known by his <i>nom de plume</i> Voltaire, was a French Enlightenment historian, philosopher and writer. He was famous for his advocacy of freedom of religion, freedom of speech and separation of church and state, often attacking the Catholic Church through his wit and writings.<br/><br/>

Voltaire was a prolific and versatile writer, with more than 20,000 letters and over 2,000 books and pamphlets to his name, as well as plays, poems, essays and historical and scientific works. Despite the strict censorship laws of the time, Voltaire often spoke up in favour of civil liberties, and regularly used satire to criticise intolerance, religious dogma and other pillars of French institutions of his day.
