The magic lantern, also known by its Latin name lanterna magica, was an early type of image projector that used pictures—paintings, prints, or photographs—on transparent plates, one or more lenses, and a light source. Because a single lens inverts an image projected through it, slides were inserted upside down in the magic lantern, rendering the projected image correctly oriented.
Christiaan Huygens, Lord of Zeelhem, was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution. In physics, Huygens made seminal contributions to optics and mechanics, while as an astronomer he studied the rings of Saturn and discovered its largest moon, Titan. As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, the most accurate timekeeper for almost 300 years. A talented mathematician and physicist, his works contain the first idealization of a physical problem by a set of mathematical parameters, and the first mathematical and mechanistic explanation of an unobservable physical phenomenon.
Frans van Schooten Jr. also rendered as Franciscus van Schooten was a Dutch mathematician who is most known for popularizing the analytic geometry of René Descartes.
Sir Constantijn Huygens, Lord of Zuilichem, was a Dutch Golden Age poet and composer. He was also secretary to two Princes of Orange: Frederick Henry and William II, and the father of the scientist Christiaan Huygens.

JohannesHudde was a burgomaster (mayor) of Amsterdam between 1672 – 1703, a mathematician and governor of the Dutch East India Company.
Nicholas (Nikolaus) Mercator, also known by his German name Kauffmann, was a 17th-century mathematician.
In mathematics, particularly in geometry, quadrature is a historical process of drawing a square with the same area as a given plane figure or computing the numerical value of that area. A classical example is the quadrature of the circle . Quadrature problems served as one of the main sources of problems in the development of calculus. They introduce important topics in mathematical analysis.
Grégoire de Saint-Vincent - in Latin : Gregorius a Sancto Vincentio, in Dutch : Gregorius van St-Vincent - was a Flemish Jesuit and mathematician. He is remembered for his work on quadrature of the hyperbola.
Lemme Rossi was an Italian music theorist. He was the first to publish a discussion of 31 equal temperament, the division of the octave into 31 equal parts, in his Sistema musico, ouero Musica speculativa doue SI spiegano i più celebri sistemi di tutti i tre generi of 1666. This slightly predates the publication of the same idea by the scientist Christiaan Huygens.
Salomon Coster was a Dutch clockmaker of the Hague, who in 1657 was the first to make a pendulum clock, which had been invented by Dutch mathematician Christiaan Huygens (1629-1695). Coster died a sudden death in 1659.
The phrase temperament ordinaire is a term for musical intonation, particularly the tempered tuning of keyboard instruments. In modern usage, it usually refers to temperaments falling within the range of tunings now known as "well-tempered".
Lodewijck Huygens was a Dutch diplomat.
Constantijn Huygens Jr., Lord of Zuilichem, was a Dutch statesman and poet, mostly known for his work on scientific instruments. But, he was also a chronicler of his times, revealing the importance of gossip. Additionally, he was an amateur draughtsman of landscapes.
Probability has a dual aspect: on the one hand the likelihood of hypotheses given the evidence for them, and on the other hand the behavior of stochastic processes such as the throwing of dice or coins. The study of the former is historically older in, for example, the law of evidence, while the mathematical treatment of dice began with the work of Cardano, Pascal, Fermat and Christiaan Huygens between the 16th and 17th century.
Horologium Oscillatorium: Sive de Motu Pendulorum ad Horologia Aptato Demonstrationes Geometricae is a book published by Dutch mathematician and physicist Christiaan Huygens in 1673 and his major work on pendula and horology. It is regarded as one of the three most important works on mechanics in the 17th century, the other two being Galileo’s Discourses and Mathematical Demonstrations Relating to Two New Sciences (1638) and Newton’s Philosophiæ Naturalis Principia Mathematica (1687).
Treatise on Light: In Which Are Explained the Causes of That Which Occurs in Reflection & Refraction is a book written by Dutch polymath Christiaan Huygens that was published in French in 1690. The book describes Huygens's conception of the nature of light propagation which makes it possible to explain the laws of geometrical optics shown in Descartes's Dioptrique, which Huygens aimed to replace.
