comment Fun math puzzle
@NoahS -- by this site you meant this MO site (I am on a war path against pronouns). I gave you +1 for being helpful anyway. This chat will not last long. The q. is doomed to vanish, and for a good reason (thus to down-vote this question is a waste of energy :-)

comment Is g( ) rational if it looks that way on a large rational subset?
The M.A., good job!--you turned a nothing q. title into something sensible.

BobAlex, first you show a sense of humor, which was nice! (There is far from enough of this around here). But now you're whining--stop it, and look for a proper place on Internet.

You need to find a proper Internet place for this question. MO is not one of them.

Such problems are notoriously impossibly hard. You need to ask an eight year old mathematician to solve it for you in a blink of an eye.

comment Inverse limit in shape theory
I could write a minimal (brief) exposition of theory of shape for compact spaces and abstract categories in that compact direction. It'd take a separate MO pseudo-answer though. Otherwise, there is my Fund.Math. paper or monograph Shape Theory by J.-M. Cordier and T.Porter.

comment The story about Milnor proving the Fáry-Milnor theorem
Tucker's bad joke possibly meant that it was not an assignment given by an instructor (Fox) to a student (Milnor) but by a student for an instructor (i.e. student Milnor asked indirectly his instructor Fox a favor).

comment Inverse limit in shape theory
@FernandoMuro -- right, it'd be more precise. However shape category and shape theory are sometimes used as synonyms (shape theory rolls the tongue smoother, I think).

comment Will this be a case of self plagiarism or will it annoy the referee?
Is there any reason or excuse to have this question on MO?

comment The ordered pair (3,100) indicated that it costs $100 for a job that is 3 hours work. He charges $190 for 13 hours of work
Q1: slope -- Himalaism; Q2: intercept -- American Football; Q3: scenario -- Cinematography; Q4: 6 hours -- Astronomy; Q5: charge -- Electromagnetism. You ask 5 different questions which address 5 widely different topics. On MO you are supposed to concentrate on one topic per question.

comment Intrinsic definition of arc length
@LiviuNicolaescu -- I am sure you meant any cusp like a curve given by two equations and one double inequality: $\ z=0\quad y^2=x^{21}\quad 0\le x\le 1.\ $ This curve looks worrisome at the original but fine when the radius $\ r>0\ $ is small (and approaches $0$).

comment Intrinsic definition of arc length
@LiviuNicolaescu -- a good idea about cusps (for contradicting my argument) but my volume formula does work for cusps anyway since with the radius approaching $0$ the overlap near the cusp gets small (proportion wise). BTW, I disregarded your formula above since it seems mistyped, I think--you described simply a plane (not a curve) $\ x=y\ $ or I am confused.
