We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
In 1882, Klein imagined sewing two Möbius Loops together to create a single sided bottle with no boundary. Its inside is its outside, it contains itself, and you can almost do it yourself… but not quite because you’ll need a fourth dimension to get the surface to pass through itself without making a hole.
Well, if you can’t make one, you can always buy one, at Acme, of course, http://www.kleinbottle.com/. Yep, no doubt about it: Your Acme's Klein Bottle is a real Riemannian manifold, just waiting for you to define a Euclidean metric at every point.
