It is impossible, in principle, to explain any pattern by invoking a single quantity.
Interesting phenomena occur when two or more rhythmic patterns are combined, and these phenomena illustrate very aptly the enrichment of information that occurs when one description is combined with another.
There is a strong tendency in explanatory prose to invoke quantities of tension, energy, and whatnot to explain the genesis of pattern. I believe that all such explanations are inappropriate or wrong.
What is the pattern that connects the crab to the lobster and the primrose to the orchid, and all of them to me, and me to you?
