His father, Constantijn, was a famous statesman, scientist, poet and musician. From 1645 to 1649, Christiaan studied at Leiden University and Breda before returning home to the Hague. There, he developed new ideas in mathematics, mechanics and optics. In 1655, he built a telescope with which he discovered Saturn's rings and one of its moons. He also designed and built the first working pendulum clock. In 1666, Huygens moved to Paris to become the director of the Académie des Sciences. While he was there, he published the classic work Horologium Oscillatorium, in which he gave a complete mathematical description of the pendulum and a description of his improved pendulum clock. In the same year, he produced a kind of engine which ran on gunpowder, although it didn't work very well. enlarge Christiaan Huygens In 1675, he built a chronometer which used a balance wheel and a spiral spring instead of a pendulum. Robert Hooke had tried in 1660 to control a clock using a straight spring but Huygens' was the first to work properly. Balance wheels and spiral springs were used in almost all watches until the invention of the quartz crystal oscillator. Huygens returned to the Hague in 1681 and published his second classic work, Traité de la Lumière in 1690. In this book, he explained refraction by suggesting that light was a kind of wave. In 1693, he announced his theory of the conservation of mechanical energy.

Fu anche il primo a scorgere segni (reali) su Marte, anche se i tratti riportati sono sicuramente di dimensioni maggiori di ciò che aveva visto. Questi tre disegni eseguiti da Huygens, sono i primi che si conoscano che mostrino segni evidenti della superficie del pianeta.

PERSONNALITES HUYGENS Christiaan Physicien et mathématicien néerlandais (La Haye, 1629 — id., 1695). En 1642, Huygens a treize ans, Galilée meurt en résidence surveillée à Arcetri, près de Florence, Isaac Newton naît à Woolsthorpe, en Angleterre, et Descartes vient d'achever la rédaction en latin de ses Principes de la philosophie. D'une génération intermédiaire entre Galilée et Newton, ni pionnier ni véritable fondateur, Huygens est cependant celui qui, par la profondeur de ses recherches et la rigueur de ses écrits, a rendu possibles le développement et la constitution d'une véritable physique mathématique. Christiaan Huygens naît à La Haye le 14 avril 1629. Issu de l'une des familles les plus importantes des Provinces-Unies, très liée à la maison d'Orange, il reçoit une excellente éducation, à laquelle participe activement son père, Constantijn Huygens. Ce dernier, intéressé par la pensée baconienne et l'avènement de la nouvelle science, est aussi en relations épistolaires avec des hommes comme René Descartes ou Marin Mersenne. Un milieu privilégié L'aisance financière de la famille comme l'extrême compréhension et l'aide intellectuelle de son père permettent à Christiaan Huygens de se consacrer entièrement, dès l'âge de vingt ans, à la science. Son activité scientifique peut alors être divisée en trois grandes périodes correspondant à ses lieux de résidence successifs: de 1650 à 1666, à La Haye, chez son père; de 1666 à 1681, à Paris, à la Bibliothèque du roi, où il participe activement aux travaux de la nouvelle Académie royale des sciences; enfin, de 1681 à sa mort, en 1695, de nouveau en Hollande, entre La Haye et Hofwijck, près de Voorburg, où il met la dernière main à la rédaction de son Traité de la lumière.

Christiaan Huygens Jef Pennings 4V2, 15 juni 2001 Het begin Christiaan Huygens is geboren op 14 april 1629 in Den Haag. Hij was de tweede zoon van Constantijn Huygens en komt uit een welgestelde familie. De intellectuele eisen die Constantijn aan zijn gezin stelde waren erg hoog, Christiaan zal hier later zijn voordeel van hebben. Nadat Huygens uitgebreid de theorieën van Galileo Galilei had bestudeerd kwam hij in de jaren 1655-56 met zijn eigen ideeën. Zo ontdekte hij met een 83 meter lange eigen gemaakte telescoop, waarin door hemzelf zijn jongere broer Constantijn geslepen lenzen in zaten, dat Saturnus omgeven was door een satelliet, namelijk Titan. Een paar maanden later geeft hij een nauwkeurige omschrijving van een ring van Saturnus. Ook dit was waargenomen met zijn zelf gemaakte telescoop. Weer een jaar later ontdekt hij "de nevelvlek van Orion". Al zijn opvattingen en waarnemingen publiceerde hij in het boek 'Cosmotheoros', hierin verdedigde hij het standpunt van Copernicus en probeerde hij aan te tonen dat ook op andere planeten behalve de aarde levende wezens voorkwamen. Huygens is nu ook astronoom geworden. Hiermee is hij wel afgeweken van de leer van Descartes en zijn idealen. In 1660 vertrekt Huygens naar Londen. Hier staat hij direct in contact met de belangrijkste geleerden van die tijd. Deze waren verenigd in de Royal Society. Hier heeft Huygens de sfeische aberratie bestudeert die in lenzen kan optreden. Dit toonde aan dat Huygens nog volop belangstelling had voor optica.

Branch of Science Physicists Nationality Dutch Huygens, Christiaan (1629-1695) Dutch physicist who was the leading proponent of the wave theory of light In (1690), he developed the concept of the wavefront but could not explain color. The wave theory, however, was supported by the observation that two intersecting beams of light did not bounce off each other as would be expected if they were composed of particles. In contradiction to Newton , Huygens correctly believed that light must travel more slowly when it is refracted towards the normal, although this was not proven until experiments by Foucault in the nineteenth century. Huygens also made important contributions to mechanics, stating that in a collision between bodies, neither loses nor gains "motion" (his term for momentum ). He stated that the center of gravity moves uniformly in a straight line, and gave the expression for centrifugal force as Additionally, he studied pendula He discovered Titan and was the first to correctly identify the observed elongation of Saturn as the presence of Saturn's rings. Huygens was also the mentor of

His father Constantin Huygens had studied natural philosophy and was a diplomat. It was through him that Christiaan was to gain access to the top scientific circles of the times. In particular Constantin had many contacts in England and corresponded regularly with Mersenne and was a friend of Descartes Tutored at home by private teachers until he was 16 years old, Christiaan learned geometry, how to make mechanical models and social skills such as playing the lute. His mathematical education was clearly influenced by Descartes who was an occasional visitor at the Huygens' home and took a great interest in the mathematical progress of the young Christiaan. Christiaan Huygens studied law and mathematics at the University of Leiden from 1645 until 1647. Van
