Consider a wire frame of arbitrary shape dipped in a soap solution. Plateau, a Belgian physicist, observed that the soap film forming in the frame will tend to assume the smallest possible area amongst all surfaces spanned within the frame. The problem of describing this minimal surface became known as 'Plateau's problem'. The study of this problem, since its inception due to Lagrange in 1760, has revealed connections to several areas in mathematics and physics.
