I would define a torus as a "circle looped in a circle".
Where *loop* takes on the connotation of *blowing a bubble*.
But I would not define the (hole in the middle) as a circle.
The projection of the inner edge of the torus onto a plane
is a circle.
A torus has no edges.
OK, so you're not familiar with the concept of projection
onto a plane. Since a circle also has no edges, it's also
impossible to create a projection of a circle onto a plane,
right? Hint: The answer is "No, it's quite possible". And
the projection of a torus onto a plane is a pair of
concentric circles; the projection of the "hole" is the
inner circle.
And your delusions are projecting.
And for lesson 101 in hypocrisy we have...
So we can add "hypocrisy" to the list of terms you don't
understand...
Since when we look "down" onto the torus our
eyes are essentially viewing that plane it's perfectly
reasonable, although not mathematically rigorous, to
describe the "hole in the middle" as a circle.
Ah. Bun that would be *totally* "mathematically ridiculous" to
do the same with the earth?.
Of course not. Ummm... Who mentioned the Earth, and what's
the relevance to a projection of a torus onto a plane, other
than the fact that both are mathematically valid procedures?
And where did the quote "mathematically ridiculous" come
from? *I* certainly didn't use it in this thread. Perhaps
that's where your spurious "hypocrisy" accusation came from;
your failure to remember who said what, and in what thread?
