At dVerse for Haibun Monday, qbit/Randall suggests we try “a description… in which you describe one particular member or element of a set.”

My haibun:

 

Surface tension in terms of energy of molecules…

Molecules touching neighboring molecules are in a relatively low state of energy. If they were not in contact with neighbors, they would have a higher energy.

Interior molecules have as many neighbors as they can possibly have. Boundary molecules are missing neighbors and so have a higher energy.

A liquid minimizes energy state by minimizing boundary molecules. This process results in a minimal surface area as the liquid surface takes its smoothest shape.
