nb. for nrxns and leftists: I'm using 'devaluation of masculinity' in an economic sense: masculinity is objectively worth less now.
@St_Rev @themattsimpson I’d vote for hyperreals as the right way, but Cauchy is indeed clearer than Dedekind. Picked that up later.

@Meaningness @themattsimpson Hyperreals have their own technical problems. Cauchy sequences lead more smoothly into topology. -
@St_Rev @themattsimpson Oh, that’s interesting… yes, I see that…

@Meaningness @themattsimpson You can do topology with generalized hyperreals but you have to fiddle with filters. -
@St_Rev @themattsimpson That makes vague intuitive sense, actually, although it would take a while to swap filters back into my head!

@Meaningness @themattsimpson I did actually once have a graduate analysis course that used nets https://en.wikipedia.org/wiki/Net_%28mathematics%29 … it wasn't too bad.Thanks. Twitter will use this to make your timeline better. UndoUndo

@Meaningness @themattsimpson (Nets are equivalent to filters, that's the connection)Thanks. Twitter will use this to make your timeline better. UndoUndo
