|Proportions: Proportions are comparisons of two ratios, written as equations with two equal fractions. They are used to solve problems involving rates, ratios, and percentages. See also Measurements, Comparisons, Comparability, Numbers._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Measure/Ratio/Proportions/Feynman: since every relationship is largely close to a rational relationship, we can treat every relationship as precisely as we wish.
Proportionality/To the Square/Feynman/(s): proportionality is not simply about "correspondence", otherwise we could say that it did not matter whether something is proportional to the simple or the square. It is rather about the fact that the sizes are the same, if different baselines are chosen.
