physics theory
    #22184845 - 09/03/15 08:25 PM (8 years, 4 months ago)

pi*radius^2= area of circle (2 dimensional)
(4/3) pi*radius^3= volume of sphere (3 dimensional
(x/4) pi*radius^4= ____ of _____ (4 dimensional)

Been a good while since I took calculus/physics but I remember wondering about this even when I completely understood it.

I think I can speak for 99% of the shroomery when I say that I(we) have no idea what the fuck that is.

But I have always been jealous of people who could do that math. Respect

4th dimensional volume is hypervolume. Dont know what the shape would be though. 4th dimensional cube is hypercube, so maybe just hypersphere.

I don't understand what you're asking. Are you wondering why the math works the way it does?

Also, google a video of the rotation of a hypercube. It is pretty mind blowing to think that what is happening is analogous to a cube in three dimensions spinning on an axis. There are some pretty cool rotation images out there for how 3 dimensional objects would appear if they were rotating in 4 dimensions.

These are referred to as hyperspheres or n-spheres, where n is the number of dimensions. The volume, V, and the surface area, S, are:

V2n+1 = r2n+1 * 2n! * (4*pi)n / (2n+1)!

where 2n+1 is the dimension of the sphere.

Sn-1 = rn-1 * 2 * pin/2 / Gamma(pi/2)

where n-1 is the number of dimensions.

Was I supposed to learn this in Calc III? I don't remember any of that shit :lol:

You do get a bit of 4th dimensional volume when you learn triple integrals. But no, that really wasnt a big part of the curriculum.
