Answer 1

Answer:

The title says it all, really. Reading through Reed & Simon's book on functional analysis, I have now reached the chapter on topological spaces, and the notion of a net is introduced there to handle things that 'sequences' can't quite manage. It's just not clear to me why it should be called 'net'. I'm interested in this since it may help me develop my intuition for the concept.
