How Does a Real-Life Escherian Staircase Work?

In this video I show you a 3d printed infinite staircase also called an Escherian staircase after M.C Escher. I talk about how this staircase can actually be possible in Nil space using non-euclidean geometry.

Infinite stairway is...

In science: Escherian staircase
In real life: escalator

[redcharget]

“Infinite stairs are impossible”
slopes: *are you sure about that*

[moonlightmando]

Am I the only one who saw the dropoff without the reveal? No wonder why I was confused of how it even was an illusion.

1:56 ''it's not quite the shape you'd expect''
Exactly the shape I expected

This one didn't quite work. I could see the drop off from the beginning. It didn't look like you were going up on that corner, but down. I know the idea of the trick, but it didn't work for me this time.

2:28 is it just me or that looks like a shoe

Edit:wow guys this is prob my most popular comment thanks😊

Slope was obvious to me, looked like a slope even from fixed angle. Didn't realize it was that steep though.

[neutronenstern.]

ok lets make a slide in a nil Geometry and have fun and free energy.

"Its not a shape you'd expect"

*Actually is what i expected*

[researchers]

*Imagine the office staircase being like this one*

One of the best "real time" demonstrations of this Escher phenomenon was in the 1986 film The Name of the Rose, a Medieval mystery starring the great actor Sean Connery. In it he and his protege discover a hidden library in an old monastery that can be reached only by climbing stairs that cannot possibly exist since, at one point, they are facing each other on stairs on opposite sides of the tower--and they are each upside down to the other. Once they are in the library, they go down stairs from one room to another only to eventually end up in the original room! Quite a fascinating section of film that has never (to my knowledge) been duplicated since. If you've never seen the film, it is well worth finding and watching. The key is whether you can solve the mystery before they do!

You are the first person I've seen to show the actual shape of the srairs! I knew there was a trick to it but seeing it I can visualize exactly what is going on! Great video! This whole video is awesome!

2:59 why is there Unus Annus music in the background? *confused screaming and crying about what's gone*

We should have a one hour version of him waking the LEGO person up the stairs

[robinbrowne]

It's just like when I tell my grandkids Time to go up to bed. No matter how long they take, they never get there :-)

The Action Lab: its real infinite stairs
Me: hes just turning the lego guy

"It's not the shape youd expecte"
No that's exactly the shape I expected

I would love for someone to make a real-life staircase like this. I've climbed 30 flights of stairs one time, and felt just like this. None of the floors have the number from the stairwell, so it felt like it gone on for infinity. The real question is, would a person know they were on an infinite staircase? Or the brains eventually tell them, something isn't right here? Much like how people get lost and end up doubling back where they started.
