and I quote "If a mathematically perfect sphere, rests on a mathematically perfect plane, the sphere touches the plane at exactly one point.
The area touched is exactly zero.

That's not quite the same as no area at all - it just means that the area is infinitely smaller than any given area unit."

Now how impressive does contact sound? Although I believe this to be good evidence as to why we shouldn't be calling contact balls: 'spheres' Unless you're using this:

or maybe this:

They say the only thing smoother is a neutron star, something which can also be said about Bootsy Collins .

Briney, that's exactly the reason why I think a ball can be balanced ANYWHERE.

Sit it on a flat surface, and the area of contact is tiny. all we need to do, is learn to keep our balance point as still and as level as the flat surface... not so easy.
