π: ratio of circle's circumference to it's diameter

we can generalize this concept to n dimensions

1_π: what we generally call pi, or the ratio of a 1-sphere's circumference to the line bisecting it: 2πr/2r = π
2_π: ratio of 2-sphere's surface area to the area enclosed by the 1-sphere bisecting it 4πr^2/πr^2 = 4
3_π: ratio of 3-sphere's surface volume to the volume enclosed by the 2-sphere bisecting it 2π^2r^3/(4pir^3/3) = 3π/2

in general, n_π is the ratio of an n-sphere's (n-1) bounding surface space to the space enclosed by the n-2 sphere bisecting it: given by the equation:

n_π = 2√π * Γ((n+1)/2)/Γ(n/2)

From this we can see that in even dimensions n_π is a rational number but in odd dimensions n_π is transcendental.

consciousness can only exist when π is transcendental, our space is conveniently 3 dimensions

you exist due to pure anthropic chance

what the fuck am I reading

ok

A 3-sphere has a 3-dimensional measure as its surface. So surface volume.

The arxiv one has nothing to do with anything. The other one doesn't mention Pi or transcendental numbers.

But that's not extending the same concept to higher dimensions.

The first concept is:
The ratio of a distance to the size of the set of all points that distance from a point in two dimensions.

The second concept is;
The ratio of that set in n dimensions to that set in n-1 dimensions.

Of course the second one is going to be simple in even dimensions.

I thought that was a 4-sphere

The fuck is a surface volume?

The surface of a volume

LOL RIGHT

What's the surface volume encapsulate?

3d analog of the surface area of a sphere

a sphere (or 2-sphere) is 2d, it has a volume of 0, but it encloses a 3 dimensional space (a ball) with a volume of (4/3) pi r^3

a 3-sphere is 3 dimensional but encloses a 4-dimensional space

Your confusion stems from the fact that people confuses circles and spheres with the area they enclose and use it synonymously in every day language. A disc has area, a circle doesn't, a ball has volume, a sphere doesn't.

Thanks, that clears things up. Whenever people talk about 4-spheres they're actually a dimension up from what I'm imagining...damn.

>>7699864
In 3 dimensional space, the set of points equidistant from one point (what you think of when you hear "sphere") is a 2 dimensional object. Think of a beach ball. So, it has a 2 dimensional measure of the space it takes up. This is called "surface area."

In 4 dimensional space, the set of points equidistant from one point is a 3 dimensional object, so, it takes up a 3 dimensional space. This space it takes up is it's "surface volume" (as volume is 3 dimensional).

Fucker already got it for me :P

>>7699864
this is the observable universe with earth as the center

pretend if you traveled to the edge of the universe you'd suddenly wind up on the other side like pacman

the volume of this universe is the "surface volume", it encloses a 4d hyperspace that you can't access because you can only move in 3 spatial dimensions

I can't fathom a perpendicular in 4-dimensional space. Can't a perpendicular point relative to a sphere's center exist at all possible points inside of a sphere??

Although that's also implying perpendicular = parallel.
