Hypercube (and further diminsions)
November 14, 2015 at 12:43 pm
(This post was last modified: November 14, 2015 at 12:44 pm by Combanitorics.)
Lately I've concluded that the only dimension higher than the third that I really understand is the fourth. It appears to me that since there can be a general solution to fourth order equations, that hypercubes must exist, since it's possible to describe one perfectly with algebra, and since such an algebraic description is always possible with the fourth order formula.
I'm still working on the further generalization of the cube to n dimensions. Does anyone have an idea how to visualize that, or know of a really good link?

I can only work with the mathematics, higher order dimensions are then very simple. Imagining what it would "look like" becomes nearly impossible for me at just 4 dimensions.

Higher order polynomials also have solutions, I don't understand what you think is special about four in that respect...

Well it is more then a little mind bending when you try to imagine what it may look like.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

You might like to try this 4D Rubik Cube:

I can do the boring old 3D one, but this gives me a headache.
(There's also a link to a 5D version, for those who consider sanity to be something that only applies to other people.)

MIT is working on 4d printing and thats really interesting.

Well. I've found my next research project.

(IANMTU)
A piece of string is essentially one dimensional (length) and in our three (physical) dimensional world it can be manipulated in those extra dimensions without damage.
So to, a sheet of paper is 2 dimensional (length and width) but can be manipulated in the third dimension without damage, like being rolled up and unrolled for instance.
It turns out a 3 dimensional object (such as your body) if it was placed into a 4 (physical) dimensional 'universe', it could be manipulated in that 4th physical dimension in surprising ways, WITHOUT damage.
Yes, starting at your anus (what is it with so many of my posts winding up there??) you could be turned inside out, and then turned back again the way you were, without breaking any bones, without killing you, and without any pain. This topic was breached in Star Trek, curiously, and a (IIRC) Klingon battle cruiser had its crew 'inverted', but unfortunately, the effect was not reversed. They didn't show it, just made reference to the crews 'shameful' condition, presumably before they were euth'd by their fellow, un-inverted Klingons.
The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
