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 Dupin cyclide In mathematics, a Dupin cyclide or cyclide of Dupin is any geometric inversion of a standard torus, cylinder or double cone. In particular, these latter are themselves examples of Dupin cyclides. They were discovered by (and named after) Charles Dupin in his 1803 dissertation under Gaspard Monge. The key property of a Dupin cyclide is that it is a channel surface (envelope of a one-parameter family of spheres) in two different ways. This property means that Dupin cyclides are natural objects in Lie sphere geometry. Dupin cyclides are often simply known as "cyclides", but the latter term is
