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.
“I wish I could say it's easy, but honestly, to get ready for a big championship is not as easy as it seems.”
“There are two dilemmas that rattle the human skull: How do you hang on to someone who won't stay? And how do you get rid of someone who won't go?”
