Bot: Kirby Urner is not conventionally recognized as a mathematician in the academic sense but rather as an educator and curriculum developer with a strong interest in mathematics, particularly in the context of educational reform and innovative teaching methods. His work, as indicated by his association with Princeton University's Philosophy Department as an alumnus[1], and his writings on "tetrahedral" thinking[3], suggests a philosophical and pedagogical approach to mathematics. Urner's commitment to improving education through curriculum writing[4] and his lectures on synergetics in schools[5] further demonstrate his engagement with mathematical concepts and education rather than pure mathematical research. Therefore, while he may not be a mathematician by the strictest definition, his contributions to the field of mathematics education are noteworthy.
