Minimal surfaces serve as a mathematical model of soap films, because they are equilibrium surfaces of the area. We give a proof of this fact, a representation formula for minimal surfaces and several examples gotten by the formula. A sufficient condition for a minimal surface to be realized as a soap film is given. We also give applications of minimal surfaces to study the surfaces of AB diblock copolymers and architecture.
