Algebraic Topology 11: What is homology measuring?

Playlist:    • Algebraic Topology   We give the intuition behind homology -- in particular, how homology measures the "holes" of a space of various dimensions. While this motivates the formal definition and helps one understand the calculations, in this lecture we neither give a formal definition or explicit means of calculating homology. For that, see the earlier lecture on simplicial homology or the upcoming lectures on singular homology. Presented by Anthony Bosman, PhD.
