The key is in the word "infinitesimal" which in this case does
not mean "very, very, small" but means "arbitrarily small but
not zero".

A positive infinitesimal is not arbitrary small, but is smaller
than any positive real.

And yet positive reals may be found arbitrarily close to zero.

Yep. Which means that, considered in relation to what people "know" about
real numbers, infinitesimals are at least somewhat Weird, and the rules they
play by don't always extend back into the real numbers intuitively.

Another way to think about it is by visualizing real numbers as a mesh, and
infinitesimals as a mesh with much finer weave...

ObSF, since as near as I can tell, though I'm missing about half the posts
in this thread for some reason, it's only posted to r.a.sf.w: Rudy Rucker's
_White Light_ and the various descriptions of the transfinite side of Cim\"on.
