Zadig approach instructive, and wrote in his 1880 article "On the Method of "Zadig"": Edgar Allan Poe may have been inspired by "Zadig" when he created C. Auguste Dupin in "The Murders in the Rue Morgue", which Poe called a "tale of ratiocination" and which established the modern detective fiction genre. Émile Gaboriau and Arthur Conan Doyle were perhaps also influenced by "Zadig". As Barzun and Taylor put it in "A Catalogue of Crime": "However implausible and "agrarian" his method, he is the first systematic detective in modern literature, and that priority itself adds to his troubles in the story until
Dupin cyclide also used to refer to a more general class of quartic surfaces which are important in the theory of separation of variables for the Laplace equation in three dimensions. Dupin cyclides were investigated not only by Dupin, but also by A. Cayley und J.C. Maxwell. Today, Dupin cylides are used in computer-aided design (CAD), because cyclide patches have rational representations and are suitable for blending canal surfaces (cylinder, cones, tori, and others). There are several equivalent definitions of Dupin cyclides. In formula_1, they can be defined as the images under any inversion of tori, cylinders and double cones. This shows
