"Not Knot!" Who's There? "The Doctor..."

So, last night, I couldn't sleep, and so was "seeding" my YouTube Favorites with Classic Doctor Who, to skew it away from Sesame Street just a bit (though Classic Sesame Street continues to be awesomesauce). So searches for "TARDIS" got me onto related vids on fourth-dimensional geometry, and computer animations of the same.

That sparked an interest in more. And this afternoon, I tried searching for Fifth Dimensional geometry (since Susan says, in An Unearthly Child, that space is five-dimensional); all that led me to discover is that there is some sort of band called "5th dimension."

But I did find this in a playlist: Not Knot (Part 2/2), all about topology and new-fangled mathmatical theories about the theoretical spaces around theoretical knots. Um... Yeah. I'm not claiming to understand much... I just let the soothing narrator's voice wash over me while I zoned out to psychodelic images.

But: here's what I caught about half-way through (the whole vid is just about 8 minutes long):

~ 4:19 - 4:42: "Just as we tiled regular space with cubes, we've tiled hyperbolic space with regular dodecahedra. Let's fly around a little in hyperbolic space to get a better feel for it. Notice how quickly apparent size changes as we move. This is one of the biggest qualitave differences between our regular space, and hyperbolic space."

Dudes! Is this why the TARDIS appears bigger on the inside? And why the Doctor rolls his eyes every time someone mentions it? It's just the way everything normally appears to him?

Sorry, don't mind me. I just get squeeful when the real 'verse intersects with any one of my favorite fictiverses.

I'm such a geek.
