wow, maybe is not such a good idea without an anti-mirror protection :-)

No, but I'll try to download a free book from wikipedia wikibooks,
thanks :-)

wow, a 4D ghost :-D imagining is just great, someone has to do a movie
out of this, is just too good to be just a Math tale. 4D gravity, that
will be a problem since the simple "shadow" of a hypercube looks
bizarre, imagine a true hypercube or more complex object or people, how
gravity, being normal to a 4D surface by definition, affects the 4D
matter, man! *blows mind*, if mathematicians help get this to the movies
will break the Academy Oscar record set by Lord Of The Rings... assuming
non-math-friendly-people don't go to sleep or exit the movie yelling for
a refund...

yeah, wow, assuming they understand our language, this is getting more

Thanks for this, I'd save this and the previous info for future
reference. I have always liked Math over any other science, I'd be a
mathematician if it were a Degree anywhere near my city; Math seldom
bores me, all the opposite, is lots of fun :-)

OK, I'll take your word for it :-) and I'll start looking on this
"frustratum" :-D to start with and then go through the 8 sides.
Thanks for all the info pal.
Cheers.

Oh! coincidence, wikipedia has it
(http://en.wikisource.org/wiki/Flatland), thanks anyway :-)

You seem to know an awful amount of Math, you have a Degree on it or
something related to it?

I have an Internet connection and too much free time. ;-)
Actually, I have an honors degree in Computer Science, which is closely
related to mathematics. (However, this is only what it says on the sheet
of paper; it was "really" a degree in Information Technology, which is
quite different...)
When I did my maths GCSE, I only got a C. But that was back when I
thought "maths" just meant doing endless runs of pen and paper
calculations...

have seen all 4 Cube movies, even the '70s one.
Cheers.

I have. I liked Cube better. I didn't know there were more.

I liked Cube²:Hypercube better because of the wonderful weirdness of
waking up inside a 3d Cube which was part of a 4D cube, all the
fascinating theories and convoluted plot and the non-sense ending was
just classy for me, I only wish I had know more Math and understand was
was the cylinder that psychiatrists brought back, but for me was the
best anyway :-)
Ironically Cube 0, was the fourth movie and explain how the first Cube
was build, is very interesting and creepy like the res of them. The
first one was: Man in a Cube, literally; was a UK idea originally at the
seems, there was a German version of Man in a Cube too, I don't
understand much German so I didn't saw it completely.

It's good to know that some people are taking the idea of a fourth
spatial dimension seriously. A lot of people argue that time is the
"true" 4th dimension, but that idea just doesn't sit well with me, even
though I don't have a lot of knowledge in this area.

Yeah. I think maybe with our 3D minds we could travel through the fourth
dimension, yet not be able to witness it directly as we do the 3rd. More
speculation, I know. It might have been inspired by something...

Oh I see, well even I like Math there is a point where get really
complex, so unless you devote your life to it you won't get an A from a
teacher I think or you are some kind of genius. I have been the victim
of those intellectually wain teachers that won't let you get more grade
than they think you deserve even when I have proven them wrong according
to a particular Math concept that they taught us to begin with, so I
wouldn't worry much about a grade, you know what you know and life will
grade you more fairly when the grade don't depend on biased humans.
