I hope the pain this morning is just the rain. Please, God, it is not tension on vertebrae L-5 due to the burst fracture of vertebrae T-8. This is the stuff of engineering 101; Where is the load on my spine now? Where is it going? What will deform next as my spine seeks equilibrium?
Engineering stress is the applied load divided by the original cross-sectional area of a material. Also known as nominal stress.
True stress is the applied load divided by the actual cross-sectional area (the changing area with respect to time*) of the specimen at that load.
* This is what is known as the, “WTF, in High School I was captain of the football team! I had a body to die for!” factor.
Engineering strain is the amount that a material deforms per unit length in a tensile test. Also known as nominal strain.**
** This is what laymen refer to as “Oh, Mother of God, please, make the pain stop!
True strain equals the natural log of the quotient of current length over the original length as given by… ***
*** I got nothing. My head just exploded. Math is the language of physics and while physics simultaneously intrigues and frightens me I have no clue what’s going on. I embody the mental equivalent of “Don’t mind me, I’m just banging rocks together.”
This morning I would like to think I am a unique and individual human being blessed with singular gifts. Turns out I am just nominal strain’s b^tch. ****

While cowering under my blankets, hiding from the morning pain a neighbor came by to let me know there was a faun in my garden. This is the “Life still comes at you no matter what you are going through factor.” This is a dual factor; 1) Cute, or good, 2) In five years this faun could become 5-10 more deer ravaging my ‘sustaining native pollinators’ gardens or bad. Sometimes this factor just is; so much background actors sent up from Central Casting.
My husband came in and found me wandering in pain circles. When I shared my health concerns he looked at me with dumbfounded revelation. “I’ve been in a lot of pain today. Huh.” And so, he assuaged my fears, refilled his coffee and went back to tinkering on the boat.
Sometimes it’s just the rain.
