As the transfinite portions are direct consequences of the axioms themselves, TO is saying that he wants to accept only those parts of a unified whole that he can understand, and reject everything he can't. > > > > What does it mean for a conclusion to be incorrect?

Except that TO cannot point out any point of it which is more fictional than mathematics as a whole. > Not all operations possible with finite numbers are possible with the > T-riffic numbers, but I don't see as they contradict finite numbers in > any way. That TO claims he cannot see a problem is not evidence that no problem exists, as TO's vision in things mathematical has long since been shown to be considerably less than 20/20. Only when TO has produced mathematically valid proofs of his claims will anyone take any of them seriously. Handwaving is not enough TO!

You don't need it. Meaning that TO's IFR doesn't even work for finite sets. TO has admitted that cardinality at least works right for finite sets.

Suppose we let B represent Big'un; then B*1/B = 1, where 1/B is an infinitesimal. Then what you are saying means 1/B = 1/B 1*1/B = 1/B (B*1/B)*1/B = 1/B B*(1/B*1/B) = 1/B B*(1/B^2) = 1/B Since 1/B is infinitesimal, its square is not distinct from 0; so... B*(0) = 1/B 0 = 1/B So 1/B is identical to 0. Where is my error? Cheers - Chas

Where is my error? Assuming that Tony's definition of infinitesimal has anything to do with any standard definition of infinitesimal. :) Stephen

Actually, I also learned a lot from the describing - which makes it not a waste that TO apparently garnered nothing from it. Wasn't that Aatu K.'s second reason for arguing with cranks?
