A minimal surface is a surface that locally minimizes area, characterized by having zero mean curvature at every point.
Soap Film: A soap film is a thin layer of liquid soap that forms a surface with minimal area due to surface tension, often used to illustrate the properties of minimal surfaces.
Mean curvature is a measure of the curvature of a surface, defined as the average of the principal curvatures at a given point, crucial in identifying minimal surfaces.
