Outrageously Funny Word Dictionary :: Greywacke

👉 Greywacke is a term used in mathematics, specifically in the field of algebraic topology. It refers to a type of algebraic variety that is not smooth and has no rational points. Greywackes are also known as non-orientable surfaces in three-dimensional space. Greywackes can be visualized as two-dimensional geometric shapes that are "grey" because they have no edges or corners. They are often used to study the geometry of higher-dimensional spaces and their topology.
