Behold! The Grand Problem: the Circle Squared Beyond Refutation: No Longer Unsolved [Or] Mathematical and Geometrical Demonstrations

Beschreibung

Diagrams and figures, some folding; Large 8vo 9" - 10" tall; 128 pages; [SIGNED] 1931 Self-published by the author. Soundly bound in original black cloth, front board stamped in gilt with circular and square design and bold titling; gilt lettering at spine dulled and almost illegible. A key work of early 20th-century mathematical crank literature Heisel s privately printed "solution" to the classical problem of squaring the circle, offered here "beyond refutation. " Often cited in literature on pseudoscience and mathematical fallacies, including Martin Gardner s Fads and Fallacies in the Name of Science. This copy inscribed by the author on the front free endpaper: "To my dear niece, Mrs. A. J. Lyons [? ] from Carl Theodore Heisel, April 16th 1931." Notably accompanied by a manuscript letter from a recent prior owner seeking a mathematician s opinion on the validity of Heisel s work the owner proposed to use it in a middle-school math class. Also laid in is a photocopy of Charles Hadlock s article "Field Theory and its Classical Problems" presumably provided in response, as an implicit refutation. Binding sound; cloth with light shelf wear and corner rubbing, mild surface spotting to boards; gilt on front board bright but much dulled at spine. Contents clean and fresh. Heavily illustrated throughout with geometric figures, including numerous fold-out diagrams. A scarce signed copy of this celebrated American mathematical curiosity, with interesting provenance.
