Maybe you could provide an example of how a pig might fly in the
normal meaning of the phrases.

Maybe the pig came to earth from planet zork in the 43rd dimension
from our causal reference and has super powers on earth.
Maybe an earth pig with swine flu was infected by a bird with bird flu
while eating radioactive swill and grew wings.
maybe a pig drank red bull

Please enlighten me.

It's simply the way that it is. Algebra over the real numbers is one of
many different rings. Rings in general are only one subset of groups.
There are axioms that define the properties of groups in general, then there
are specific additional axioms that define particular kinds of groups, then
there are additional axioms that define rings within groups. Then there are
additional axioms that define particular kinds of rings. Then there are
additional axioms which when applied to a specific kind of ring give us our
everyday algebra. By applying different axioms you can define other
algebras that work fine as mathematical systems but are not particularly
useful for anything.

Yes, I know. However, there exist posters in this thread who don't
even know about real-world utility. I figured out after I posted the
above reply that the poster knew the difference.

I think you and the pig are over his head...

You cannot talk about reasoning without talking about or mentioning
truth. But of course, in your case and in the case of all the
basketweavers (your peer review group), no one knows the hell of what
they are talking about. Did something bad happen to all of your brains
or have you all been that way a long time?
