Where i can find information about 4th and 5th dimensions?
Well i can see that the 4th is the a three dimensional projection of the cube surface, but i do not understand the 5th.

>>7494130
>>7494128
>>7494106

So aside from the direction/dimension thing what would be the 5th dimension ?

You can pinpoint a location with 3 dimensions, but that point can move in time. So you need 4th dimension as time to pinpoint it. If this is the case, then I'm guessing 5th dimension would be alternate realities or alternate universes which in some other universe, the point is not in the same place or time, relative to the current universe.

In our XYZ universe, what if gravity pulls objects in the W-direction? Do you think it is possible? Might help thinking about an 2D universe having a XY-plane.

to this?

let me show you an other dimension in a simple way.

1 + 6


although the answer is pretty clear, it is not show, still it popped up in your head.

think of a other dimension as intelligence, which is not thought, because thoughts can be show, so there are part of our 3d world. Just because you can't see throu a skull and tissue does not mean there is nothing moving there. But the sum of it's parts creates the next dimension.

an other example

X walks from his house to the mall.
It's a straight walk, no one around and he meets no one on his way. He leaves at 1.15 am.
When he opens tries to open the door of the mall, it's 1.45 am.


Even it is no quest for you to find out how long it took him to get there, it easy for you to see.
You know something that isn't there to observe in a physical manner. It's the sum of its part that help you to find the 'hidden' truth.

I hope this helps you

Hello /sci/,

given a particle with mass <span class="math">m[\math] in a 3D harmonic oscillator with a potential
<div class="math">
V(\vec{x}) = \frac{1}{2} m \omega^2 \vec{x}^2
[\eqn]
find the differential equation for the radial part of the wavefunction (using spherical coordinates and the separation of variables (or functions, in this case))
b) Show that the radial wave function for angular momentum <span class="math">\ell = 0[\math] can be reduced to the eigenvalue equation for a simple 1D harmonic oscillator. Hint: Use R(r)=u(r)/r[\math]

Hey there, /sci/. I'm starting my newest semester in college, and one of my classes is Modern Algebra.

Problem is, I don't really understand it. Previously, I've worked on problems with inherent assumptions (i.e. Calculus, Computational Math, etc.), but I can't grasp working with groups or cosets or kernels.

I was wondering if you guys have any resources to get at least some understanding of Modern Algebra material. I'd be happy with even an infographic.

Thank you.
