ABSTRACT
All areas of science start with a classification system to organize the central concepts in these disciplines. In biology, for instance, the classification of plants and animals, as well as three other “kingdoms” of living things, serves as the organizational basis for knowledge in the related fields of zoology, botany, microbiology, bacteriology, virology, and so on. When students take chemistry in high school, they are asked to memorize at least part of the classification of elements as shown in a “periodic table” to organize our knowledge about the basic building blocks of physical chemistry. In mathematics, glossaries list the symbols, often designated by Greek letters, representing the standard mathematical functions, such as summation, finding a derivative, and the determinant of a matrix.
