Mobius Strip ProblemYou have strip 1 and 2 connected at the ends (flattened) see pic.. Spooooon!!! #2 20130627 12:27:50
Re: Mobius Strip Problem1. Yes. You just need to flip one of them. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Mobius Strip ProblemHave you tried makng them and flipping on of them?

Re: Mobius Strip ProblemSorry, The flipping did not work. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Mobius Strip ProblemThe first one isn't. The second one is. The first one has a 3x180 degree turn, while the second one has just 1.

Re: Mobius Strip ProblemWell as long as there are an odd number of 180 degree turns then it's called a mobius strip. As long as it has only 1 face. Last edited by phanthanhtom (20130627 18:49:46) #7 20130627 18:51:23
Re: Mobius Strip ProblemWell, not really. First of all, the number of 180 degree turns must be odd. Second, it depends on the definition of the Möbius strip.

Re: Mobius Strip ProblemI have edited my post and it says odd now. Anyway, odd is enough. In Vietnam any strip with twists are called Mobius strip, whatever the number is, but internationally it's either a) 1 twist b) odd number of twist. I like the b definition more. #9 20130627 18:58:32
Re: Mobius Strip ProblemWell, it is true that topologically, as long as the parity is the same, the strips are the "same". I do not remember what the relation is called, but, either way. one cannot be turned into the other without going to the 4D space.

Re: Mobius Strip Problem
I agree. Anonymnistefy, have you seen that it has only one face? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
