See 4-D Space With 3-D Glasses

purpleant writes: "A hyperplane is a 3-dimensional space that slices through the 4-dimensional space, the same way a 2-dimensional plane can slice through our 3-dimensional space. The bounding hyperplanes can be extended infinitely so that they criss-cross through each other, chopping up hyperspace into many 4-dimensional 'chunks.' Again the inner chunks are finite, and they are distributed in shells around the core polytope. The HyperStar applet displays those finite chunks, one shell at a time. The inner shells are complete -- each shell completely encases the previous shell. The outermost shells have holes in them."

  1. 4 Dimensions by Anonymous Coward · · Score: 0, Funny

    In my complex analysis class at University, my professor said it was easy to visualize 4 dimensional functions. He proceeded to draw some kind of squiggle on the chalkboard and said, "There, just don't be close minded". We didn't laugh.

  3. Reminds me of a story... by Overcoat · · Score: 2, Funny
    All this talk about envisioning 4-d space reminds me of an interview Forced Exposure did many years ago with SF writer/mathematician Rudy Rucker, who has written extensively about dimensional spaces beyond the third, both in fiction and nonfiction. I couldn't find the interview online anywhere, but the exchange went something like:

    FE:So, what's the closest you ever came to experiencing the fourth dimension?

    Rucker: Well, there was this one time, we'd been partying all night, and I wanted to get a little higher. We were almost out of drugs, but I did have some acid. So I took it, but then I fell asleep. And when I woke up...

    FE: Oh, I've been there. That's the fourth dimension?

    so it's 5 am monday morning on the east coast and i decide to check out slashdot before going to bed for 4 hours of shuteye before work tomorrow (don't ask, crazy weekend). i am bleary eyed, brain dead, exhausted.

    and i read "The bounding hyperplanes can be extended infinitely so that they criss-cross through each other, chopping up hyperspace into many 4-dimensional 'chunks.' Again the inner chunks are finite, and they are distributed in shells around the core polytope."

    dudes! my functional iq right now is about 50! if you are going to post these kind of stories on slashdot, could you PLEASE post them around, say 3pm on a thursday? thanks ;-P

    i should be awake by then, and i promise i will come back and try to wrap my mind around this story at that time... grumble, grumble
