I got one of those Klein bottles from him, and it's really beautifully done. If you are careful, you can even store some liquid or other stuff in it. I wonder if the mathematical original could do that, too.

I suppose I am compelled to get one too. Not that I want one, it's just that I already have his books - and methinks he deserves a little extra money for this video.

Cliff Stoll in case people were wondering: https://en.wikipedia.org/wiki/Clifford_Stoll I have his original book my shelf, it was fascinating when it came out. His Klein Bottle company is here: http://www.kleinbottle.com/

He's on HN, too: https://news.ycombinator.com/user?id=CliffStoll

[edit]

As my friends (online and off) can attest, I make Klein bottles mainly for fun. It's a zero-volume home business, small enough to be run from one room; the warehouse occupies the crawlspace under our house.

Of course, the best part of Acme Klein Bottles is meeting people: via email, occasional visits, talks at schools & math colloquia, and chattering about physics & LTE & coding with friends at my day-job (Hi Newfield People!). Which is to say, it'll be a while before I recast my kleinbottle website - I'm having too much fun doing other things. -- from an earlier post

The Copy on Kleinbottle.com is marvelous, its like pouring hot cocoa spiced with love:

From http://www.kleinbottle.com/drinking_mug_klein_bottle.htm :

"The 7 mm air space separates the inside from the outside, so ice water won't cause condensation. This extends the life of hot or cold drinks, saves energy, and helps stave off the dreaded local thermodynamic equilibrium."

But seriously just read the whole page, this is like a bear hug from a friend I didn't knew I had.

He has also written Cuckoo's Egg, a book about his hunt for hacker that broke into computer at Lawrence Berkeley National Laboratory. https://en.wikipedia.org/wiki/The_Cuckoo%27s_Egg This was really fascinating read for a young nerd around very early 1990's.

ahh, no wonder that name sounded so familiar!

Earlier quoted context omitted.

If you make this bowl, it will have two surfaces, with no way to get from one side to the other.

Well, I'm not sure about that. The top of my bowl is the top-half of a doughnut if you will: it really does not seem to have an edge. At what point does an "edge" appear?

the object that have only one surface, but no edge, is a klein bottle. A sphere (or if you will, a ball pressed into a bowl shape) has two surfaces - the outer one, and the "inner" one (where the "inner one" is the one you cannot reach from the outer one, as tho the surface is infinitely thin, and the bowl/sphere is made of hollowness.

It makes me sad, and is probably a failure of HN, that people like Stoll only have 7 karma and don't post here.

Real life Gyro Gearloose!!! In the next video he talks about how a Klein bottle is made, and how, contrary to a bottle, it has no edge. I'm not sure I understand why a bottle "has to" have an edge? Surely it's possible to make a bottle with no edge? For example, if one takes a sphere and progressively turns it into a bowl (by punching into it), and then makes the bowl deeper, it still has just one surface and no edge…

Run your finger around a möbius strip. Your finger touches all parts of the surface without travelling over an "edge". You can do the same with the klein bottle.

Can you do the same with your sphere/donut/bowl?
