Biography[edit]

Variorum problematum collectio, 1607

Born into the Ghetaldi
Ghetaldi
noble family, he was one of six children. He was known for the application of algebra in geometry and his research in the field of geometrical optics on which he wrote 7 works including the Promotus Archimedus (1603) and the De resolutione et compositione mathematica (1630). He also produced a leaflet with the solutions of 42 geometrical problems, Variorum problematum colletio, in 1607 and set grounds of algebraization of geometry. His contributions to geometry had been cited by Dutch physicist Christiaan Huygens
Christiaan Huygens
and Edmond Halley, who calculated the orbit of what is known as Halley's comet, in England. Ghetaldi

was the constructor of the parabolic mirror (66 cm in diameter), kept today at the National Maritime Museum

in London. He was also a pioneer in making conic lenses.[1] During his sejourn in Padua
Padua
he met Galileo Galilei, with whom he corresponded regularly. He was a good friend to the French mathematician François Viète. He was offered the post of professor of mathematics in Leuven
