Infinity symbol Infinity symbol The infinity symbol (sometimes called the lemniscate) is a mathematical symbol representing the concept of infinity. The shape of a sideways figure eight has a long pedigree; for instance, it appears in the cross of Saint Boniface, wrapped around the bars of a Latin cross. However, John Wallis is credited with introducing the infinity symbol with its mathematical meaning in 1655, in his "De sectionibus conicis". Wallis did not explain his choice of this symbol, but it has been conjectured to be a variant form of a Roman numeral for 1,000 (originally CIƆ, also CƆ), which was sometimes
Infinity and the Mind the author's personal contact with Kurt Gödel. An appendix contains one of the few popular expositions on set theory research on what are known as "strong axioms of infinity." "Infinity and the Mind" was reviewed by the "New Yorker", which asserted that "Rudy Rucker's "Infinity and the Mind" is a terrific study with real mathematical depth." Martin Gardner described the book as "Informal, amusing, witty, profound... In an extraordinary burst of creative energy, Rudy Rucker has managed to bring together every aspect of mathematical infinity... A dizzying glimpse into that boundless region of blinding light where the mysteries of transcendence
