reflexiveness in Science

reflexive

[rĭ-flĕk′sĭv]

Of or relating to a mathematical or logical relation such that, for any given element, that element has the given relation to itself. Equality in mathematics is a reflexive relation, since a = a for all a, whereas the relation of being 'less than' is not, since it is not true that a < a for any a.
