4D Toys: Klein Bottles
- junon 5y agoThe video on that page is a great explanation. Very well stated, demonstrated and produced.
- JshWright 5y agoNo discussion of Klein bottles would be complete without mentioning Cliff Stoll's Acme Klein Bottle company. https://www.kleinbottle.com/ https://www.kleinbottle.com/ His warehouse is pretty unique: https://youtu.be/-k3mVnRlQLU https://youtu.be/-k3mVnRlQLU
- kingcharles 5y agoHis warehouse is amazing. It's cooler than the Klein bottles. This guy is like a real Doc Brown with too much time on his hands.
- JshWright 5y agoI'm pretty sure I say this every time Cliff Stoll is mentioned on HN, but one of my goals in life is to be as excited about something as Cliff is about everything.
- CliffStoll 5y ago... naturally, I'm a day late to this note. All the same, it's worth mentioning that I feel like I'm a member of the HN tribe, although it's been many years since I"ve really done much creative hacking. All the same, I deeply appreciate the kindness & joy that HN people pass along. Oh, there are a still few niches where techno-oddballs are appreciated. Warm wishes, -Cliff
- JshWright 5y agoAnd four days later, the conic loaf of bread video Brady just posted is perhaps the best example yet of the level of excitement that I'm shooting for pretty much anywhere in my life (and you've found it in bread...)
- js2 5y agoI ordered a small Klein bottle from him, and the best part wasn't even the bottle I eventually received. It was the emails he sent me as he prepared the shipment, along with photos of him wrapping the bottle, his wife's garden, the bike he rides to the post office. Second best thing was the hand-written note he included thanking me for the order. Third best thing is the bottle itself, but honestly, it's just another knick-knack on my shelf.
- gallegojaime 5y agoI had the same thought, he cherishes making you laugh and having a good and interactive experience. He has different jokes for every country. When I received my Klein bottle, along came some papers from ACME with numbers and instructions. The delightful inside baseball cane when he had a field for "number of ingredients in Licor 43"!
- CliffStoll 5y agoYes! I run this zero-volume business for fun ... and the joy of meeting interesting people. So your note brings a broad smile to this tired astronomer's face. Thank yoU!
- bitexploder 5y agoSimilar story. Ordered one for my wife. Also recommend watching him on YT (Numberphile).
- willis936 5y agoI just bought one and he emailed within an hour and shipped within two. The photos and conversation were lovely. He's a role model.
- Daub 5y agoA mathematician named Klein Thought the Mobius band was divine. Said he, "If you glue The edges of two, You'll get a weird bottle like mine. —- David Pleacher (https://www.pleacher.com/mp/mpoetry/klein.html https://www.pleacher.com/mp/mpoetry/klein.html)
- Daub 5y ago"In the end, I am very proud of the illustrations I came up with.’ Rightfully so. These are easily the best visual explanations of the Klein bottle I have seen.
