21. The Schwarz surfaces have topological genus 3, the minimal genus of triply periodic minimal surfaces . 22. Between 1925 and 1950 minimal surface theory revived, now mainly aimed at nonparametric minimal surfaces. 23. This includes minimal surfaces as a subset, but typically they are treated as special case. 24. There are counterparts to the associate families of minimal surfaces in higher-dimensional spaces and manifolds. 25. A surface is a minimal surface if and only if the mean curvature is zero. 26. Structures with minimal surfaces can be used as tents. 27. See for instance the approximate numerical method for minimal surfaces form finding at Stretched grid method. 28. There is an elementary proof for minimal surfaces . 29. Brownian motion on a minimal surface leads to probabilistic proofs of several theorems on minimal surfaces . 30. Minimal surfaces play a role in general relativity.
