Now do it with a mug.
- ihaveajob 9y agoAll the pictures in that link already show a mug.
- delecti 9y agoA mug is topologically equivalent to a bagel or donut or torus.
- tzahola 9y agoT-topologically w-what?? I mean yeah, that was the point of my remark. To write something on topic as well: There was a fun little challenge on puzzles.stackexchange I think, which relied on the same construction as this article. I couldn’t find it, but it went like this: “You’re stuck on top of a tall building with nothing but a saw. There’s a ladder fastened to the side of the building, but it’s unfortunately not long enough to reach the ground; in fact it goes about half the height of the building from the top. Challenge is to get on the ground “safely”. You can cut into the ladder with your saw in any way you like and you can assume that the resulting pieces will be rigid, but won’t break under load.”
- chopin 9y agoAs far as I can tell this challenge would not require a twisted cut.
- tzahola 9y agoPlease elaborate!
- Crespyl 9y agoI think it would be possible to slice the ladder exactly in half, down its length, right? Each rung would go from a cylinder to a half-cylinder, but should still be rigidly connected to either side of the ladder all the same.
- Retra 9y agoThe problem is then you have two short ladders. You throw your two half ladders off the roof and they don't magically stand end-to-end for you. You have to cut with a twist to ensure the last rungs are entangled with each other so the half-ladders are hooked together. Then you can hang one off the other and reach the ground.
- Crespyl 9y agoSee I was envisioning one of these: http://www.bates.co.za/BMS_Product_Images/ROUND%20TUBE%20LADDER%20C-W%20HOOKS%202.5M.jpg http://www.bates.co.za/BMS_Product_Images/ROUND%20TUBE%20LAD...
