Like many ideas in mathematics, the concepts of ratio
and proportion are concerned not just with numbers
themselves, but with the relationships between numbers.
These relationships convey fundamental information
about the world. Ideas of proportion influence not only the
world of facts, but also of aesthetics—with perceptions of
harmonious proportions aecting our judgments of beauty
in art and architecture. More practically, fortunes can be
greatly aected by “compound interest,” which causes
an exponential increase over time. Understanding these
relationships helps to model real-world phenomena
and make predictions.
