The man with 1,000 Klein Bottles UNDER his house - Numberphile

I thought I recognised the name... turns out Cliff is the guy from the Numberphile videos who loves klein bottles. He is such an enjoyment to watch. [VIDEO]

Cliff is an amazing person. Just a joy! Every time I see him on Numberphile , my life is made better. [LINK] [VIDEO] P.S. Cliff, we know you're on HN. Please continue being yourself, it seems like a really great person to be!

this numberphile/Cliff Stoll video is on a different topic, klein bottles... or maybe more the travelling salesman/knapsack problem, but it's a must see. Cliff is a cool guy (whose geewhiz excitement I can only take in small doses but) he's worth following [VIDEO]

You should also watch the related video about how he stores Klein bottles under his house. It's fascinating. [VIDEO]

To learn about the operation, watch the Numberphile video, “The man with 1,000 Klein Bottles UNDER his house” [VIDEO]

Everything this guy does is hilarious and entertaining. See later talk about this event: [LINK] And he drives RC forklift under his house to store Klein bottles he's selling! [VIDEO]

Bah they forgot to mention the best bit. He keeps already-made klein bottles in the crawlspace under his house, and built a remote controlled fpv mini-forklift to retrieve them on demand: [VIDEO]

If you don't happen to have the time to visit him, here is a playlist of videos Numberphile did on Klein Bottles, his basement warehouse, the intrinsic curvature of pizza, and a whole bunch of other interesting things: [VIDEO]
