Melville Davisson Post was phonetically mis-spelt. Ellery Queen would later call the stories "an out-of-this-world target for future detective-story writers." In his 1924 book of literary criticism "Cargoes for Crusoes", Grant Overton called the publication of Post's "The Doomdorf Mystery" a "major literary event", and in "Murder for Pleasure" (1941), Howard Haycraft called Uncle Abner "the greatest American contribution" to the list of fictional detectives after Edgar Allan Poe's C. Auguste Dupin. After Post's death, more stories about Abner were written (at the request of the Melville Davisson Post estate) by the retired American research chemist, John F. Suter (1914-1996). Besides Mason, Abner,
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
