Uh, yeah, I think I understand what his numbers are. Perhaps you've seen
our recent exchange on the matter? They are discrete infinitesimals such
that the sequence of them within the unit interval maps to the naturals
or integers on the real line. Is that about right, Ross?

Only a countable infinity of them? Then the number of infinitesimals
in [0,1] is exactly the same as the reciprocals 1/n for every natural
n>0, right? But there are c reals in [0,1], so are there more reals
than infinitesimals?


I think Ross has to answer that one. In my book, the naturals are really
*N, the hypernaturals, and so there are an uncountably, actually
infinite, number of them, and then EF works for me as a special case of IFR.

TO's book only exists in TO's twilight zone.
