How much does a successful demonstration establish? →A program gives the expected output. Between “it did” and “it will” lie the test distribution, formal assumptions and deployment context. Those boundaries are easy to miss under pressure to ship.This video helps answer · How much lifetime does a successful demonstration establish?How do you update on evidence—and choose what to ask next? →A test result and a Wordle clue both rule out possibilities. The crucial difference is whether you already know the result or still have to choose the question.This video helps answer · What lies between rated watts and seconds to a boil?
Caption notes
Loose sand can spread sideways under a load. This demonstration layers thin reinforcement through the sand, then traces the result to tension constraining the grains. A car supplies a vivid load case while the materials and boundaries determine how the model scales.
