comment Relationship between measure theory and real analysis
Well, measure theory generalizes parts of real analysis. It certainly does not generalize the material on point set topology and functional anlysis in Folland's book.

comment Relationship between measure theory and real analysis
''The name "real analysis" is something of an anachronism. Originally applied to the theory of functions of a real variable, it has come to encompass several subjects of a more general and abstract nature that underlie much of modern analysis.''-Folland Where does it say that measure theory generalizes real analysis?!?! Folland writes no such nonsense.

comment Is “total boundedness” a topological property?
There is a different between bounded and totally bounded.
