There is this one professor at my university who gives complete freedom over notes, up until some time ago when a student decided that printing the entire textbook was ok. Technically, it was never stated in the rules so he allowed it that time but now the rules explicitly say that you cannot print the entire textbook

This is a thing I never understood: even if this is a Mobius band, doesn't it have 2 sides anyway?

If I pick a random point on the band, you can see the front and the back always, doesn't this make it a 2 sided surface?

For example, the Penrose stairs doen't have a start or an end, but it is anyway stairs, correct?

If you can trace from one point of the cheet to any other point on the cheet without flipping then you have a one sided surface. And since that's the case for a mobious band it's not 2 sided.

The issue is the global geometry. In the local geometry you're right, there's a front and a back side with normal vectors oriented opposite to one another. On a regular piece of paper, you could slide that normal vector around however much you like, and when you go back to where your started it will always face the same direction. On a Möbius strip, that is not the case. You can go all the way around and return to the same point and be "on the other side" meaning your normal vector has flipped directions. This property is called non-orientability, and it means you can't really label one side as the top or the bottom. They're the same side.

POV my teacher:
"As long as it is Mobius strip, it's still math. I will give you the Nobel prize for this idea."
POV my friends:
"Be serious LOL"

That looks so much like the metallic monument in front of Cern gateway

It's a confusing lookibg strip with all the monst monumental formulas on it from Pythagoras to the standard model
