Pseudomathematics is a form of mathematicslike activity that does not work within the framework, definitions, rules, or rigor of formal mathematical models. While any given pseudomathematical approach may work within some of these boundaries, for instance, by accepting or invoking most known mathematical definitions that apply, pseudomathematics inevitably disregards or explicitly discards a wellestablished or proven mechanism, falling back upon any number of demonstrably nonmathematical principles.Contents
[hide]Some taxonomy of pseudomathematics[edit]
The following categories are rough characterisations of some particularly common pseudomathematical activities: Attempting to solve classical problems in terms that have been proven mathematically impossible;
 Misapprehending standard mathematical methods, and insisting that use or knowledge of higher mathematics is somehow cheating or misleading.
Attempts on classic unsolvable problems[edit]
Investigations in the first category are doomed to failure. At the very least a solution would indicate a contradiction within mathematics itself, a radical difficulty which would invalidate everyone's efforts to prove anything as trite.Examples of impossible problems include the following constructions in Euclidean geometry using only compass and straightedge:
 Squaring the circle: Given any circle drawing a square having the same area.
 Doubling the cube: Given any cube drawing a cube with twice its volume.
 Trisecting the angle: Given any angle dividing it into three smaller angles all of the same size.
Practitioners[edit]
Pseudomathematics has equivalents in other scientific fields, such as physics. Examples include efforts to invent perpetual motion devices, efforts to disprove Einstein using Newtonian mechanics, and many other feats that are currently accepted as impossible. French psychoanalyst Jacques Lacan, and BulgarianFrench philosopher Julia Kristeva have been accused of misusing mathematics in their work; see Fashionable Nonsense (1998) by Alan Sokal and Jean Bricmont.^{[1]}Excessive pursuit of pseudomathematics can result in the practitioner being labelled a crank. The topic of mathematical "crankiness" has been extensively studied by Indiana mathematician Underwood Dudley, who has written several popular works about mathematical cranks and their ideas.
Not all mathematical research undertaken by amateur mathematicians is pseudomathematics. Many amateur mathematicians have produced genuinely solid new mathematical results. Indeed, there is no distinction between an amateur mathematically correct result and a professional mathematically correct result: results are either correct or incorrect, and pseudomathematical results, by relying on nonmathematical principles, are not about professionalism but about incorrectness arrived at by improper methodology.
