Why is the Mobius strip non orientable?
Space & NavigationSince the normal vector didn’t switch sides of the surface, you can see that Möbius strip actually has only one side. For this reason, the Möbius strip is not orientable. Is Möbius strip an orientable surface? The Möbius strip is a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns.

How do you find a vector with initial point and terminal point?
Space & NavigationVectors: Connecting the Dots (Literally!) So, you’re diving into vectors, huh? These things are super important in math and physics because they tell you not just how much of something you have, but also which way it’s going. Think of it like this: a vector is like an arrow pointing from one spot to another.
