The Three Princes of Serendip and that therefore she had had puppies a few days before." Zadig's detective work was influential. Cuvier wrote, in 1834, in the context of the new science of paleontology: T. H. Huxley, the proponent of Darwin’s theories of evolution, also found Zadig's approach instructive, and wrote in his 1880 article "The method of Zadig": Edgar Allan Poe in his turn was probably inspired by Zadig when he created C. Auguste Dupin in "The Murders in the Rue Morgue", calling it a "tale of ratiocination" wherein "the extent of information obtained lies not so much in the validity of the inference
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
