Plateau’s problem is to show the existence of an area-minimizing surface with a given boundary, a problem posed by Lagrange in 1760. Experiments conducted by Plateau showed that an area-minimizing surface can be obtained in the form of a film of oil stretched on a wire frame, and the problem came to be called Plateau’s problem. Special cases have been solved by Douglas, Rado, Besicovitch ...

Substituting for m and n in equation (1), 2t = λ n f i l m ⇒ t = λ 2 n f i l m (2)

Soap Film Geometry - Cornell University

A slightly different unsolved problem involves soap bubbles rather than films. It is known that a spherical soap bubble is a surface that minimizes its area, subject to the restriction that it encloses a fixed volume. This mathematical fact was conjectured in ancient Greece. Now consider the problem of two bubbles.
