Discovered by Hermann Schwarz in the late 1800s, this triply
periodic minimal surface is done according to two principles:

- If part of the boundary of a minimal surface is a straight
line, then the reflection across the line, when added to the
original surface, makes another minimal surface.

- If a minimal surface meets a plane at right angles, then the
mirror image of the plane, when added to the original surface,
also makes a minimal surface.

Breathers are parametric non linear waves equations. Like most sound-waves, they can hardly be seen or perceived. Their existence was made very tangible visually using the work of mathematicians such as Schrödinger, and later Dini, and Kuen.
