It would be hilarious and irrelevant if, in the middle of a Topology paper, you said "By the way, our use of 'set' in this paper is understood to be implemented by a linked list."
That is the problem with mathematics.It has no connections with reality.
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. -- Nikola Tesla
Mathematics provides a framework for dealing precisely with notions of ``what is.''
So, what is "infinity"?
Why? Because it's the abstraction that is useful.
Why not use ASSOC lits instead? It would be much easier to think about, than some abstract mumbo-jumbo requiring PhD to understand.
