Talk:Tesseract

The TARDIS in the science fiction series Doctor Who has properties analogous to the hypercube, being appreciably larger on the "inside" than it is on the "outside".
- I've just cut this from the article, since it doesn't make sense to me. I can't think of any sense in which a hypercube is larger on the "inside" than it is on the "outside". -- Oliver P. 15:58 Mar 22, 2003 (UTC)
- Could have been supposed to be a reference to how you could fold up a 3D elephant and put it in a tesseract, if you don't mind the elephant being bent, in the same way you can put a large piece of paper in a small box. But phrased like it is, it of course doesn't make any sense... كسيپ Cyp 16:17 Mar 22, 2003 (UTC)
- In fact, you don't necessarily have to fold the elephant. Consider a line and a square. In a square with side 1m you can fit (without bending) a line with length sqrt(2)m. A one-dimensional owner of the square could put the line in it, and provided that the square was positioned so that its projection onto the owner's dimension was of length 1, the owner would think of sqrt(2)-meter line as being inside a 1-meter long container. Of course, all objects are "larger on the inside than on the outside" for people from lower dimensions, since the "outside" of such an object is an infinitely small portion of it. A person capable of using a tesseract as a container should have no problems with placing the tesseract in such way that only a very small corner of it sticks out into 3D. Think "tip of the iceberg". -- Lament
unfolding the tesseract
There are 261 ways to unfold a tesseract:

Salvador Dali's famous painting Crucifixion ('Corpus Hypercubus')
shows one of the 261 unfoldings:

The Myriad Tesseract
Please read very slowly and carefully:
I'm sure you were all introduced in early childhood that 10 ones equal a ten, 10 tens equal a hundred, and 10 hundreds equal a thousand, with symbols of a 1 unit, a 10 line/stick, a 100 square, and a 1000 cube. Any Internet site showing the next term, namely, a myriad tesseract (made of 10 thousand cubes) in Java?? 66.245.73.39 01:54, 6 Dec 2004 (UTC)

Shit! This thing is insane. I never learned about this in university. Why not? I learned about fuckin matrices and shitty negative number graphs. But 4D cubes? Wow!That is the only thing apart from pi that is interesting in maths. If only u could put it onto a 2D screen tho--Wonderfool (talk) (contribs) (email) 18:29, 17 Feb 2005 (UTC)
No cursing please. Thanks. Oh, and you can, it looks like an octagon with the star inside of it. -Scythe33
