tesseract
Topic: readings
More reading of Wallace's Infinity led to another side-tour of the world of four dimensions. A tesseract is a 3D representation of four dimentions, the same way we can draw a 3D cube on a piece of paper in two dimensions. Really cool...

Talking to Ben about it, he mentioned something he read... If you are a two dimentional thing, you can "look" at a one dimentional being, or a dot - from one end of a line looking at another, per se. If you are a 3D being, which is us, we can look at a 2d object... What this means is... a 4D being... would be able to look... inside of us? Yeah, swallow that!

Anyway, I've been meaning to find a book to read that is about math and metaphysics, and this is definitely one I like. I still have to read most of Godel Esher Bach and the follow ups to that, but that's different from this. First this, then, when we are moved into the new house, that.

I thought the 4th dimension is Time (the other 3d being lenght, width, depth) and it is arguable whether time travels on a straight line? Anyway, I might be wrong about it.

well, it could be - but it depends which dimension you want to focus on - say there are many - we can only really fully comprehend 3... then you can pick from the many which you'd want to represent. The key is that they should be at 90 degree angles to each other...

(there are 10 dimensions, and an 11th disputable one) :)

What you have here is merely the shadow of a 4-dimensional cube. Of course, this isn't even a tesseract! A tesseract looks more like this:

you'll notice that if you unfold a cube, you get a cross-like shape of squares. Now imagine that same shape, but make each square section into a cube (image above) and thats a tesseract.

Now try to visualize that shape folded into a hypercube! It's hard isn't it? Yep, because its not humanly possible!
