i guess its only me still trying to digest the mathematical terms and definitions: klein bottle + sphere are considered 2d objects...

from mathworld ::

// Unfortunately, geometers and topologists adopt incompatible conventions for the meaning of "n-sphere," with geometers referring to the number of coordinates in the underlying space and topologists referring to the dimension of the surface itself. As a result, geometers call the surface of the usual sphere the 3-sphere, while topologists refer to it as the 2-sphere.

Regardless of the choice of convention for indexing the number of dimensions of a sphere, the term "sphere" refers to the surface only, so the usual sphere is a two-dimensional surface. The colloquial practice of using the term "sphere" to refer to the interior of a sphere is therefore discouraged, with the interior of the sphere (i.e., the "solid sphere") being more properly termed a "ball." //

concluding:: the tricky term in my previous post was "object". rephrasing:: both the sphere and the klein bottle are two dimensional surfaces.

for a moment i thought mathworld itself responded to my question... but i guess i was wrong =]
thanks for the explaining the terms.
