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.
Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham (Arabic: أبو علي، الحسن بن الحسن بن الهيثم‎), frequently referred to as Ibn al-Haytham (Arabic: ابن الهيثم, Latinized as Alhazenor Alhacen; c. 965 – c. 1040), was an Arab Muslim polymath and philosopher who made significant contributions to the principles of optics, astronomy, mathematics, meteorology, visual perception and the scientific method.<br/><br/> In medieval Europe, he was honored as Ptolemaeus Secundus ('Ptolemy the Second') or simply called 'The Physicist'. He is also sometimes called al-Basri (Arabic: البصري) after Basra, his birthplace. He spent most of his life close to the court of the Caliphate in Cairo and earned his life authoring various treatises and tutoring members of the nobilities.

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'.

Hunayn ibn Ishaq ( Latin: Iohannitius) (809 – 873) was a famous and influential scholar, physician, and scientist of Nestorian Arab Christian descent. He and his students transmitted their Syriac and Arabic translations of many classical Greek texts throughout the Islamic world, during the apex of the Islamic Abbasid Caliphate.<br/><br/> Hunayn ibn Ishaq was the most productive translator of Greek medical and scientific treatises in his day. He studied Greek and became known among the Arabs as the 'Sheikh of the translators'. He mastered four languages: Arabic, Syriac, Greek and Persian.

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.

Christiaan Huygens (14 April 1629 – 8 July 1695) was a prominent Dutch mathematician and scientist. He is known particularly as an astronomer, physicist, probabilist and horologist.<br/><br/> Huygens was a leading scientist of his time. His work included early telescopic studies of the rings of Saturn and the discovery of its moon Titan, the invention of the pendulum clock and other investigations in timekeeping. He published major studies of mechanics and optics, and a pioneer work on games of chance.

Kamal al-Din Hasan ibn Ali ibn Hasan al-Farisi or Abu Hasan Muhammad ibn Hasan (1267– 12 January 1319 (Persian: كمال‌الدين فارسی‎) was a prominent Persian born in Tabriz, Iran. He made two major contributions to science, one on optics, the other on number theory. Farisi was a pupil of the great astronomer and mathematician Qutb al-Din al-Shirazi, who in turn was a pupil of Nasir al-Din Tusi.<br/><br/> His work on optics was prompted by a question put to him concerning the refraction of light. Shirazi advised him to consult 'The Book of Optics' of Ibn al-Haytham (Alhacen), and Farisi made such a deep study of this treatise that Shirazi suggested that he write what is essentially a revision of that major work, which came to be called the Tanqih.
