Actually John, I believe that you need to back and repeat your
highschool class in solid geometry. There you will re-learn that it
take only one-half rotation of a circle to produce a sphere
(becasue of the circles symetry), and only one complete rotation
of a right triangel about its altitude,
to make a cone.

One half rotation can prove a circle could exist, but it does of
course take two dimensions to do such and the 2 dimension alone can
not form
a sphere.
You need a third dimension for any motion off of the 2 dimensional
plane.

p.s., I strongly favor the death penalty for ANYWAY selling drugs
to pubescent teenagers, because the results are posters like John
who hasn't even a hint of having a clue. Tell me that drugs use is
not responsible! Readers will easily see what drugs have done to
John's brain by the following content of his post. Now I really
don't care about a mature adult trying Heroin to see what it does
for them, but the prospect of selling street drugs to young kids
is particlarly abhorrent to me. Over the age of 16, were I on the
jury, I would have no hesitance to vote for the death sentence for
any drug seller pandering to school kids. My reason being, is that
the seller is ultimatlely killing his customers...this make
him/her a mass murdered, and thus deserves the ultimiate
punishment.

Therefore there is a third plane not used
through which energy may move unimpeded,
since there is no ebb and flow in this third plane.

Achieving free passage for a body
is simply a matter of synchronizing all the
third planes and moving the body along that
synchronized plane.

James, I have absolutely no idea about what you are posting.

Fact is, the rotation of a circle through 180 degrees is that which
defines a sphere. This is geometry, not physics. Physics cannot
define geometry.

Now spheres are reall great comprssed gas container, because the
stresses impored on a sphere are rather well defined in both
engineering and physics...in fact rather trivial. James, you know
this as well as I because I know that you are not simply a dumb
wrench jockey repairing cars and trucks. We both know this, and I
suspect that your library nearly equals mine, and possible more
extensive.

James, have you watched the film "Good Will Hunting". I liked that
film because I live in the area and can identify with the plot and
characters. Still, simply a movies. What you don't likely know is
that many others have shared the same life with the 'Will' shown in
the film, but moved one.

Take this for whatever it's worth. If you wish to discuss this, you
should be able to figure out my real email address. It simpy adds one
digit to what otherwise would seem obvious, something simple as apple
pie.

Dumb, I posted 180 but I meant 360 degrees of rotation. 180 degree of
rotating a circle produces a heimspher, rotating it a full 360 degrees
yields a sphere.

Harry,
You kinad had it correct, but still, it is not a rotation.
rotation can occur in the same plane as the circle.
If you shift the axis of the circle 180 it will make a sphere.
(flip it over once and trace out the curves)
If you rotate a circle, it is just like rotating a gear, it just spins on
the
same axis and stays a circle.
:)
But no matter what,
Spheres are not made with only two dimensions like the
OP thought.
a circle is 2D right to begin with.



When you study solid geometry, you find a lot of rotations of 2-D
figure to produce 3-D figures.Some are actually even rather
interesting.

I studied 3D figures and made a few too many also.
I used www.hash.com Animation master for over 7 or more yrs now.
I also studied a lot of the circles in a car, and gears and tires (circles)
that are
rotating (not the roatation when you switch places of course)
are simply going round in circles..
