An adventure in the fourth dimension...

I recently watched this insightful video of a presentation by Cliff Stoll at a recent TED conference.

I liked the video so much, I wanted to show my appreciation. I've decided to support Cliff's store - www.kleinbottle.com. I was going to buy a bottle - but why settle for that when you purchase an everyday wearable item... the Klein hat.

I have to admit... there is a bit of false advertising here. Cliff isn't actually selling Klein bottles, since it intersects itself (this creates an edge). Instead, you can think of it as a mobius strip (one side, one edge) - distorted to represent a Klein bottle in only 3 dimensions. A true Klein bottle needs a fourth division so that it does not intersect itself.

Come to think of it... since I can't observe the fourth spatial dimension... maybe this IS a true Klein bottle... hmmm... If so, I look forward the mind altering effects of wearing something that can only exist in four dimensions.

Either way, though, I'm pleased - it will at least make for some interesting looks as I walk around campus.
