The Fourth Dimension, Time, and Plato's Cave

This video comes from Rob Bryanton's Blog, Imagining the Tenth Dimension. If you are interested in higher dimensions you might want to check out his post that explores a specific asepct considered in 0, 1, 2, 3, 4 and all the way up to 10 dimensions.

Math and Mind Reading

Can YOU figure out HOW this works?

I have this one posted on my "Fun Math" page too - just the video. I haven't had a chance yet to think about the math behind it, although I'm certain it is based on mathematics. So I thought I'd post it here as well, under "explorations" to see if anyone wanted to comment on how this works - and beat me to it! Have fun!

Fractal Zoom

This is one of my favorite zooms into the Mandelbrot Set of those available on YouTube.

Rotating Hypercube

The object you see is the four-dimensional analog of a cube, just like a cube is a three-dimensional analog of a square. As you watch this video, realize there are no cubes on the "inside." The cubes you see are the outside of the shape just as squares are the outside of a cube. Look at the perspective drawings of a cube below. In the one on the right the smaller square is NOT "inside" the cube. It's just a matter of perspective, as if you are looking into a box, and the back is farther away than the front. Same thing with this video. The hypercube is ROTATING. It is NOT turning itself inside out.
