👉 The term "watthours" is often used in context of mathematics, specifically in the field of algebraic topology. In this context, it refers to a specific type of homology group associated with a topological space. In algebraic topology, a topological space X is said to have the property of being a CW-complex if there exists a simplicial complex (or a CW complex) such that every point in X can be represented as a union of finitely many disjoint
