Apply It

Turn a principle, or a problem, into an experiment

Start from either end. Pick a principle from the 80 on this site and work out where it applies, or describe a real problem and work back to the likely cause, the matching principle, and a starter experiment. Nothing you type here is saved or sent anywhere: it stays in this browser tab until you copy it out.

Do you already have a principle in mind, or a problem you're trying to solve?
