#non-orientable-surface
There’s one more non-orientable surface sex joke that I couldn’t fit in. Möbius Strip tease. There. That’s all of them. If you can think of another one, comment below.

Me, ringing room service:

"...yeah uh... a non-orientable surface peed on the bed."

"...uh huh. 70 ounces!"
The more you look at this image the more amazing it is. I promise. For example what is pouring on the bed? Why is it pouring on the bed? Why is this bedspread being advertised as holding 70 oz?

“Non-orientable surface” is a big swing and a miss by topologists. Imagine how much fun we could have telling students “The real projective plane is disoriented.”

Surely I'm not the first, but I am sticking my nonbinary/pan flag in the Mobius Strip

The Möbius strip is a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. Every non-orientable surface contains a Möbius strip.

🧪 It's really nice to see a drawing that recalls a Möbius strip, the most famous example of non-orientable surface in mathematics, on episode 7 of the season 2 of #Arcane.

A good day for non-linear thinking 🔮

The projective plane (RP2) comes to mind - a non-orientable surface (below)

Real projective space (RP3) is orientable and easier to visualise with practice - cue a link between your inner and our outer world 💡

Bureaucrats: Nooooo you can't just build a non-orientable surface to serve as a third place!

It is what is called a a non-orientable surface in topology. It’s 2D manifold against which a system for determining a normal vector (something pointing outward and away from the surface) cannot be consistently defined. Simply put, it’s impossible to define the inside versus outside of this object.

What do you mean IT CANT BE ORIENTED?!!!

The Möbius strip is a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. Every non-orientable surface contains a Möbius strip. - Wikipedia

Horseshoe theory is there to remind us that the political compass only exists on the surface of a non-orientable object

this object has a single surface, rather like a 3D version of a Möbius strip. It is what is called a a non-orientable surface in topology. It’s 2D manifold against which a system for determining a normal vector (something pointing outward and away from the surface) cannot be consistently defined.

Sweasel is, topologically speaking, a non-orientable surface, like a Klein bottle.

There is no scientific distinction between her inside and her outside.
