This is a question from a tutorial for topology manifold. It is stated as: How many charts do you need to cover the Moebius strip that has a river printed on it?
The chart was defined as"Chart: -The (chosen) subset of the d-dimensional reals that a topological manifold maps to"
I really want to put images here to help clarify but I don't have enough reputation to add images.
this question shows up from 9:40 to 13:42 in this tutorial: https://www.youtube.com/watch?v=ghfEQ3u_B6g&t=766s&ab_channel=TheWE-HeraeusInternationalWinterSchoolonGravityandLight
The answer is two but it didn't explain why.
Thanks!
You can easily cover the Möbius strip with two (overlapping) rectangles. Those are your charts.
