Surely, you don't consider the Cartesian plane to be completely unordered??? ToeKnee

An infinite unit of measure is every bit as viable as a finite or infinitesimal one. Why can't you say 2*oo>oo? I can.

Actually they have a very real relationship to finites in the infinitesimal calculus. The parts that drop out in the final calculation using infinitesimal units are terms of higher than the first power. Those are infinitesimal, compared to infinitesimals, and can be considered insignificant in the final analysis. Them's "nilpotent" infinitesimals. > > In other words just because you say "bigun" doesn't indicate if it is > a finite "bigun" or not and just because you use the phrase "number > of" doesn't indicate you have any finite number subject to arithmetic > in finite terms. > > ~v~~ Big'un is uncountably large. It's the number of points, or infinitesimal if you prefer, in the unit interval. It's also the measure of a basic dimension of the universe. In other words, within every "one" is a universe of "infinity", and this even pertains, in the non-nilpotent model, to infinitesimal "ones", or as Ross would call them, "iotas". "Epsilons" works as well, or if you must, "deltas". Depends what Greek your arguing with, I imagine. :) 01oo (btw, do you like my Zickesque signature? It's like when I sign responses to MoeBlee as "ToeKnee", though I'm starting to like TOEknee, better, what with the Theory Of Everything reference and all. Mathematical truth, tautologically determined or otherwise, IS the basis for all reality. You'll see that eventually, Herr Lester. :))

They most certainly do, as well as having infinitesimals of different dimensions. How many infinitesimals would you say a cube has, compared to a cube?

Notice the "fin" in "define"? There are two endpoints, and in between, and infinite number of intermediate points. Similarly for cubes and squares. Yes, 2^2 and 2^3 "endpoints".

Tony, let me see if I can provide an alternative line of reasoning to support my analysis. Over the past couple of years in addition to tautological analysis I've also provided analysis of angular mechanics in corrected form. And in that analysis I do make use of arithmetic combinations of finites and infinitesimals. In particular I take finites such as the radius of circles, r, and combine them with infinitesimal changes in radius, dr, showing that for any finite multiple of dr, such as ndr, the combination can change only infinitesimally such that r+ndr=r and r remains finitely constant. I don't know if you followed that discusion but the mechanics involved are identical to what you suggest. Now the problem for you and your idea of combining finites and infinitesimals arithmetically is that you can't combine finites and infinitesimals directly. In other words there is no way to say r+dr>r as you're trying to suggest because finites and infinitesimals don't lie together on a common line with the same metric. In the case of angular mechanics this is also true. However I provide a common metric for them by definitely integrating a finite velocity, dr/dt, between 0 and dt which provides a finite dr of infinitesimal magnitude. In other words you can't provide an arithmetic sum for finites and infintesimals directly without first providing a common finite metric for them through definite integration of some kind. This is how we can know arithmetic combinations of finites of finite magnitude and finites of infinitesimal magnitude. Mathematically modern mathematikers incorrectly analyze the same problem in the reciprocal terms of n/dr instead of ndr and wind up with various kinds of 00 they like to pretend follow the finites on a common real number line. However this makes the proper analysis of angular mechanics impossible unless one takes r to be an infinite and ndr to be finite. In any event I hope this clears up my perspective on analysis of the arithmetic combination of finites and infinitesimals.
