I am not sure what you are asking. Between two points in any space you can have an infinite number of sub divisions mathematically.
Physically you are restricted to the Planck length.

Физически.

Planck length then but you need a physics guy.

А при каких условиях шар будет равен сфере?

А при каких условиях шар будет равен сфере?

Why is that an important question? in mathematics they tend to use, sphere not ball.
In common speak they are the same. A ball is a sphere.

When the camel is no longer able to pass through the eye of a needle.

Разве сфера - это не поверхность шара?

 

[DaveC426913]

I don't understand what you're asking either.

1. What, in your view is the difference between a 'ball' and 'sphere'?

2. Points have zero dimensions. Any shape with one or more dimensions contains an infinite number of points.

Your question is not well-formed.

Isn't a sphere the surface of a ball?

OK, you want to talk about the surface of a sphere. Fine.

The surface of a sphere has infinite points.
The volume of a sphere has infinite points.

Значит, число пи никогда не будет посчитано?

 

[DaveC426913]

So, the number pi will never be calculated?

Certainly not by counting the points on a sphere, no!

Pi is a mathematical object, it cannot be measured in the real world to an arbitrary level of precision.

Currently, it has been calculated to 100 trillion digits.

Зачем его вообще считают? Какой в этом смысл?

 

[DaveC426913]

Why do they even count it? What's the point?

You would enjoy Carl Sagan's novel 'Contact'. It finds a nice balance between your interest in science and your interest in god. And it does so using pi.

How many minimum points can a ball consist of? How many points can a sphere minimally consist of?

Instead of size-less points, one would need an arrangement of shapes, if seeking a minimum amount of units to tile around a globular solid. A common soccer ball, for instance, consists of a pattern of 20 hexagons and 12 pentagons. But those are not stiff material -- they bend, as a ball stitched together with even fewer geometric shapes would better illustrate via maintaining its sphericity. If replaced by stiff parts, even a polyhedron made out of 30 hexagons and 12 pentagons would be just that -- a polyhedron, rather than a sphere ("perfectly" rounded).
