Most of us have been accustomed to placing the entities in our lives, both mathematical and real, in spaces characterized by an integral number of dimensions. Thus, a line has one dimension, an area two dimensions, and a volume three dimensions. The Einsteinian space-time continuum has four dimensions, and some attributes of subatomic particles are most readily considered in spaces of six or more dimensions. Mathematically, it is possible to conceive of a space with an infinite number of dimensions.
