He was able to devote most of his life to research in mathematics without having the problems of earning a salary. Mydorge studied geometry and physics. He published books on optics and conic sections , for example De sectionibus conicis contains a wealth of new examples and ideas which were used by many later geometers. His work simplifies many of Apollonius 's proofs. He was interested in mathematical recreations and edited Mydorge's book was published in 1630 and later books, such as one by Denis Henrion (1659) were often based on it. Mydorge left an unpublished manuscript of over 1000 geometric problems and their solutions. It was not only mathematical problems which interested Mydorge. He also worked on light and refraction in particular. His interest in optics also fitted in with an interest in making astronomical observations. He was a close friend of

Claude Hardy Born: 1598 in Le Mans, France Died: 5 April 1678 in Paris, France Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Claude Hardy was a practising lawyer and took part in the weekly meetings of Roberval Mersenne and others. He was also a friend of Gassendi and Mydorge . Hardy introduced Mydorge to Descartes Hardy, in his capacity as a lawyer, worked for the Parliament in Paris from 1625. A year later he was certainly attached to the court of justice in Paris as a counsellor. In 1630 he published Examen and in 1638 Refutation . These works dealt with the problem of the duplication of the cube and Hardy pointed out a fallacy which had arisen regarding this problem. Hardy took part in many of the mathematical discussions and arguments of the time but his greatest contribution was his knowledge of Arabic and other languages which enabled him to make important Latin translations of Euclid 's Data and other books. Despite the fact that he introduced Mydorge to Descartes , Hardy supported Descartes when the two had a dispute over Fermat 's method of maxima and minima, a forerunner to the calculus.

'Mydorge's work on conic sections contains hundreds of problems published for the first time, as well as a multitude of ingenious and original methods that later geometers frequently used, usually without citing their source' (DSB). Mydorge (1585-1447) was a friend of Descartes, Fermat, and Mersenne. He was drawn to the study of optics by Descartes, for whom he designed lenses for Descartes' researches. 'Like Fermat, he belonged to that elite group of seventeenth-century scientists who pursued science as amateurs but nevertheless made contributions of the greatest importance to one or more fields of knowledge' (ibid.).

His works on conic sections contain hundreds of problems published for the first time, as well as a multitude of ingenious and original methods that later geometers frequently used. According to Baillet, he succeeded Viète as the premier mathematician of his day. He studied the properties and nature of light and refraction, and he studied vision.

He embraced the study of mathematics at the age of fourteen. He travelled to various regions of the country earning a living from private lessons. He continued to educate himself by attending classes at the universities in the regions he visited. In Bordeaux where he met Fermat and took on François du Verdus as a pupil he may have attended the university. 5. Religion Affiliation: Catholic He is buried in the church of St. Severin.

Roberval Gilles Personne de Roberval Er is geen afbeelding van Roberval Links naar anderstalige sites: De tijd van Roberval Over Roberval Ook ontdekte hij manieren om vlakke krommen te beschrijven en raaklijnen aan vlakke krommen te berekenen. Ook hield hij zich bezig met de barometrische experimenten van Torricelli, met de mathematische slinger (waarover hij met Descartes van gedachten wisselde) en andere natuurkundige instrumenten. Roberval overleed in Parijs op 27 oktober 1675 p r . (Eigenlijk gebruikt hij daar een eigenschap van verschuiven - namelijk dat de oppervlakte gelijk blijft - die later het 'principe van Cavalieri' is genoemd!)

~ Sciences et techniques ~ Gilles Personne (ou Personier) de Roberval Roberval, près de Senlis (?), 1602 - Paris, 27 octobre 1675 balance romaine © CNAM, Musée des arts et métiers / Studio CNAM balance " Roberval " © CNAM, Musée des arts et métiers / Studio CNAM Éclipsé dans l'historiographie par Fermat, Pascal ou son grand adversaire Descartes, Roberval n'a guère laissé à la mémoire collective que le modèle de balance qu'il soumit le 21 août 1669 à l'Académie royale des sciences. Depuis le colloque organisé en 1975 pour commémorer le tricentenaire de sa mort, les travaux de Kokiti Hara, de Pierre Costabel, d'Alain Gabbey, de Jean Dhombres, de Vincent Jullien ont ramené à la lumière un esprit " pointilleux et opiniâtre " qui fut un des premiers géomètres de son temps. Né probablement en 1602 aux environs de Senlis, dans un milieu humble, Roberval s'instruisit lui-même, un peu partout en France, et gagna son pain en donnant des leçons. En 1628, il vint à Paris et fut admis dans le cercle savant groupé autour du Minime Marin Mersenne.
