Homogeneity and heterogeneity

A homogeneous feature is uniform in composition or character (i.e., color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.

[1][2] The words homogeneous and heterogeneous come from Medieval Latin homogeneus and heterogeneus, from Ancient Greek ὁμογενής (homogenēs) and ἑτερογενής (heterogenēs), from ὁμός (homos, "same") and ἕτερος (heteros, "other, another, different") respectively, followed by γένος (genos, "kind"); -ous is an adjectival suffix.

[3] Alternate spellings omitting the last -e- (and the associated pronunciations) are common, but mistaken:[4] homogenous is strictly a biological/pathological term which has largely been replaced by homologous.

From atoms to galaxies, plants, animals, humans, and other living organisms all share both a common or unique set of complexities.

Scientific literature in ecology contains a big number of different terms for environmental heterogeneity, often undefined or conflicting in their meaning.

Heterogeneous solids, liquids, and gases may be made homogeneous by melting, stirring, or by allowing time to pass for diffusion to distribute the molecules evenly.

For example, adding dye to water will create a heterogeneous solution at first, but will become homogeneous over time.

[12] A mixture can be determined to be homogeneous when everything is settled and equal, and the liquid, gas, the object is one color or the same form.

In sociology, "heterogeneous" may refer to a society or group that includes individuals of differing ethnicities, cultural backgrounds, sexes, or ages.
