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."

Ad Hoc Technologies

Tools and devices developed for specific, often temporary purposes—jury-rigged fixes, makeshift solutions, one-off inventions that solve a particular problem and then are discarded. Ad hoc technologies are the opposite of engineered products: they're not designed for mass production, not tested for reliability, not intended to last. They're what you build when the thing you need doesn't exist and you need it now. Duct tape and paperclip solutions, software patches that fix one bug, temporary structures that become permanent—all are ad hoc technologies. They're ugly, fragile, and brilliant in their context. They're the technologies of making do.

Ad Hoc Technologies Example: "He built an ad hoc technology to keep his laptop cool—a folded paper wedge and a desk fan. It worked perfectly, looked ridiculous, and would never be sold. Ad hoc technology had done its job: solved a problem, right now, with what was at hand. When the fan died, he'd build something else."

Ad Hoc Engineering

The practice of designing and building solutions for specific, often temporary situations—engineering without the luxury of planning, testing, or mass production. Ad hoc engineering is what happens in emergencies, in remote locations, in startup offices, in any situation where you need something to work now and can't wait for proper engineering. It's the art of the temporary fix, the makeshift solution, the structure that only needs to stand for a while. Ad hoc engineering is despised by professional engineers (who value reliability) and beloved by everyone else (who value results). It's engineering for the real world, where most problems are unique and most solutions are temporary.

Example: "She practiced ad hoc engineering in her apartment, building a bookshelf from cinder blocks and planks, a desk from a door and sawhorses, a headboard from an old fence. Nothing would survive a move; everything worked perfectly here. Ad hoc engineering wasn't permanent, but it was home."
