sphere & pseudosphere maximum Surface area Contact? Is it 10% #393 Correcting Math
Archimedes Plutonium wrote: Alright, I have to retrench somewhat here. Looking at Mathworld's pseudosphere and funnel equations, that the contact nested inside is a line contact and not area. So I have to retrench the model and operation. What I do is cut the sphere into half and then cut a ... 6 Feb 2010 11:52

Geometry surface area Contact; related to "flatness"; Pedestal-Geometry #386 Correcting Math
Diving into a new subject for me. Call it Pedestal-Geometry. Another name maybe Anti-Calculus Geometry. Another name maybe Surface Contact Geometry. This subject harbors alot of false ideas and misconceptions. Take for example two perfect spheres. No problem here because the only contact or pedestal would b... 4 Feb 2010 16:51

Cantor's Diagonal?
Hi all, I have some difficulty digesting the diagonal argument of Cantor's. The argument is that the set of all infinite binary sequences cannot have a bijection to the set of all natural numbers, thereby proving that the former set is uncountable? However the argument looks to me to be so designed as to rea... 14 Feb 2010 00:53

The set theoretic content of the transfinite recursion theorem
As usually stated the transfinite recursion theorem on ON seems more a syntactic statement than a truly set theoretic one (i. e. a statement about formulas rather than about sets). So, what is its set theoretic content? Is it the existence of the delta-approximations? That is, the existence of functions g with d... 5 Mar 2010 13:57

Models of set theory vs. models of first order theories
Those of you who are contributing to my posts here (for which I am very grateful) may know by now that I am having some trouble to obtain, let us call it a "unified picture" of the contents of Levi's "Basic Set Theory", Kunen's "Set theory. An introduction to independence proofs" and Shoenfield's "Mathematical Logi... 19 Feb 2010 10:59

found the 10% in Geometry; Poincare dodecahedral space; 36 degree twist; matched-circles #378 Correcting Math
So Wikipedia says this about the Poincare dodecahedral space: --- quoting --- The Poincaré homology sphere (also known as Poincaré dodecahedral space) is a particular example of a homology sphere. Being a spherical 3-manifold, it is the only homology 3-sphere (besides the 3-sphere itself) with a finite fundamental... 2 Feb 2010 16:36
