cardann.

Brit.

/ˈkɑːdn/, U.S.

/ˈkɑrˌdæn/,

/ˈkɑrd(ə)n/

Forms: also with capital initial.

Origin: From a proper name. Etymon: proper name Cardan.

Etymology: < Cardan (1559 or earlier in English texts), Anglicized form of the surname of Geronimo (also written Gerolamo, Girolamo) Cardano (1501–76), Italian mathematician, scientist, and inventor: see further cardanic adj. Compare Jérôme Cardan, the form of Cardano's name often used in French texts.Cardano published his solution of cubic equations in 1545 and is credited with making the gimbal suspension known to his contemporaries, although he did not invent it.

I. Compounds.

1. As a modifier or in the genitive. Designating concepts, mechanisms, etc., devised or described by Geronimo Cardano, or attributed to him, esp. (a) designating a formula for solving cubic equations; (b) designating drive mechanisms incorporating universal joints and gimbals.

1675 J. Collins Let. 10 Apr. in H. Oldenburg Corr. (1977) XI. 258 When the AEquation hath but one roote as NA Cardans rules will find the same either accurately if the Binomialls have accurate Cube rootes, otherwise quam propinqissime.

1844 J. R. Young Elem. Treat. Algebra (ed. 4) v. 164 It is worthy of remark that the values of x and y, as exhibited in example 5, page 161, lead very readily to a certain expression, known by the name of ‘Cardan's Formula’ for the solution of Cubic Equations.

2004 Sci. Amer. (U.K. ed.) July 83/1 The Cardan grille method..appears to be a mechanism by which the Voynich manuscript could have been created.

a. cardan joint n. a joint or coupling which allows free movement in any direction of the parts joined; esp. one which can transmit rotary motion from one shaft to another set at a variable angle to the first; = universal joint n. at universal adj., n., and adv. Compounds. [After French joint a la Cardan (1865 or earlier).]
