: The topological way of saying a space is in "one piece." The text defines connected spaces and path-connected spaces, illustrating how continuous functions preserve these properties. 6. Metric Spaces
: Even though topology is abstract, drawing "blobs" to represent open sets and mappings will help you visualize the logic of a proof. The book covers a wide range of topics,
How can we rigorously define a "neighborhood" or "closeness" without using a physical ruler or a metric distance formula?

Compactness is the topological generalization of a set being closed and bounded in Euclidean space. Long covers the Heine-Borel property, Bolzano-Weierstrass property, and Alexander’s Sub-base Theorem. A major highlight of this section is the proof and implication of , which states that the product of any collection of compact topological spaces is compact. 6. Connectedness
