Sybrandt Cardinael

from Wikipedia, the free encyclopedia

Sybrandt Hansz. Cardinael , also Sybrant Hanssen, (* 1578 in Harlingen , † 1647 in Amsterdam ) was a Dutch mathematician ( arithmetic master ) and surveyor in Amsterdam.

Life

Cardinael was a member of the Mennonite Church . In 1605 he settled in the Nieuwe Nieuwstraat in Amsterdam, where his future father-in-law had an arithmetic school. He married Levijntje Panten in 1607, with whom he had six daughters. Cardinael taught arithmetic, geometry, navigation, barrel measurement, astronomy, land surveying and bookkeeping in an arithmetic school he ran. In 1614 his geometry book appeared, which established his good reputation as a mathematician. It covered a variety of subjects and was translated into German (by Sebastian Kurtz in 1617) and English (by Thomas Rudd in 1650). He was called in by the Admiralty in 1617 to assess the solutions to the longitude problem and was dismissed a year later as a teacher at the academy of Samuel Coster , a forerunner of the Athenaeum Illustre , as only Reformed and no Mennonite teachers were wanted.

He was against the use of algebraic methods in geometry, contrary to the mainstream of the time. In his geometry textbook there are also innovations such as Stewart's theorem (questions 33, 34) and he found elegant constructions in question 97 (construction of a chordal quadrilateral ) and 92 (division of a triangle into two equal parts where the dividing line is divided by one given point). He also published conventional arithmetic textbooks and a number of school books and took a stand against the heliocentric worldview of Nicolaus Copernicus in a book from 1635. As in his rejection of algebra, this showed his conservative attitude.

He was licensed as a surveyor in Friesland. In a poem by Joost van den Vondel , the latter calls him the Frisian Euclid .
