 That is to say, it is the Analogue of Space, not in the sense in which we formerly regarded Space as the negation of Matter; but in the sense of Infinite Dimensionality, or of Dimensionality in all directions, as a vague generalization from the three spatial dimensions Length, Breadth, and Thickness.

 This often happens, for example, when a twodimensional solution is obtained for data whose appropriate dimensionality is higher.

 Finite Dimensionality of de Rham Cohomology:
 Proposition 5.3.1. If the manifold has a finite good cover, then its cohomology is finite dimensional.

 The difficulties in implementing classification algorithms as is, on high volume databases, derives from the increase in the number of records/instances in the database and of attributes/features in each instance (high dimensionality).
