Ad Hoc Sciences

The systematic study of ad hoc constructions—temporary solutions, situational explanations, one-off fixes—and their role in human affairs. Ad hoc sciences examine how ad hoc reasoning works, when it's appropriate, and how it can be improved. They study the psychology of ad hoc (why we invent what we invent), the sociology of ad hoc (how temporary fixes spread or die), and the history of ad hoc (which temporary solutions became permanent). Ad hoc sciences are themselves somewhat ad hoc—developed for this purpose, in this context, without claiming universality. They're the science of making do, and they make do themselves.
Example: "He studied ad hoc sciences, learning how to generate temporary solutions that worked well enough for now. His dissertation was titled 'The Epistemology of the Temporary: How We Know What Works for Now.' The committee found it either brilliant or ad hoc—they couldn't decide which. He graduated anyway, which was ad hoc enough."

Ad Hoc Science

The practice of doing science in an ad hoc manner—developing hypotheses for specific cases, testing solutions in particular contexts, building theories that explain local phenomena without claiming universality. Ad hoc science is what happens when you can't wait for general theories, when you need answers now, when the situation demands action before understanding. It's the science of emergency rooms, of startup pivots, of parenting—contexts where general principles help but specific solutions are needed. Ad hoc science is not inferior; it's just different. It's science for the real world, where most problems are local and most solutions are temporary.
Example: "She practiced ad hoc science in her garden, trying different combinations of plants, soil, water, and sun until something worked. She didn't develop general principles; she just found what worked here, in this plot, this year. Next year, she'd start over. Ad hoc science wasn't publishable, but it grew vegetables."

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
