👉 The term "feynness" is a mathematical concept used in the field of computational algebraic geometry. It was introduced by the mathematician Andrew Wiles in 1993 as an extension of Fermat's Last Theorem, which was one of the most difficult unsolved problems in mathematics at that time. Feynman's theorem states that "a polynomial equation with integer coefficients has a solution if and only if it is solvable by radicals." However, this statement does not
