-----UPLOADER NOTES-----

This is the full version! My previous upload cut off some of the credits. I was having troubles with the audio when I tried using Premiere to combine the videos manually. Thankfully, FFmpeg did a fantastic job of connecting the VOB files without any audio loss. Enjoy!

I'm always looking for more info on this. If you have any more resources to look into, a physical copy of the video, or know someone involved in making it, please let me know in the comments!

[IMPORTANT] I have not monetized this video and never will. Any ads you see are a result of youtube changing their terms of service to allow for ads to play on any video regardless of their participation in the YouTube Partnership program.

Update [09/12/2021]: Broken links have been fixed, with a few new ones added. New videos in the works!

----DESCRIPTION----

The computer animation Outside In explains the amazing discovery, made by Steve Smale in 1957, that a sphere can be turned inside out by means of smooth motions and self-intersections. Through a combination of dialogue and exposition accessible to anyone who has some interest in mathematics, Outside In builds up to the grand finale: Bill Thurston's "corrugations'' method of turning the sphere inside out. Along the way, the narrators discuss the related case of closed curves and why they generally cannot be turned inside out. Everyday analogies such as train tracks, belts, smiles and frowns are used throughout, all richly animated and complete with sound effects.

Fun Fact: The narrators are named Xanthippe and Yorick, aptly abbreviated in the script as X and Y.

What really amazes me is that people managed to visualize this before animations existed.

[awnaurno]

Ughh dont yall hate it when u accidentally pinch ur spheres infinitely tight? It so annoying smh 😤😤😤

[Grey-The-Skeleton]

Watching this vid is such a gamble. There's a 50/50 chance of it being about either geometry, or about a woman who's denying her incestual relationship with her brother, who are themselves born of parents who are siblings.

[Charon.]

9:17 I can't even begin to imagine how hard it must have been to come up with this, using nothing more than pen, paper and your mind

[carykh]

i am impressed with this upscaling! The original was such a classic, but it was so low-res

[krissa]

this feels like 2 eternally curious gods speaking to each other

[mr.mcphoenix]

These voices give me major scifi AIs discussing if human life has value

“Am I supposed to believe you can turn a sphere inside out but not a circle.”
“Y e s”

[semicharmedkindofguy]

I think about this and my head hurts, and then I think about coding the animations for the video and my head hurts even more

[martiddy]

The fact that the original animation was made in the year 1994 is mind-blowing.

[BAN]

Huggbees' video actually helped to understand the theoretical part until it descended into that emotional mess. Without it, I doubt I'd be able to catch up with anything in this video before switching it off or fall asleep. I'm here to see the rest of the explanation.

[darbythegamer]

Wait a second…THERES AN ORIGINAL??? Theres no drama??? No incest??? NO DESTROYED MARRIAGES?!?!?

[cosmic_pepsi]

everything about this video is so surreal
the colors, the smooth slow animation, the sound effects, the AI-like voices, the VHS buzz
and the complicated, mathematically abstract science behind this, which works with real, visual objects
the initial task is unreal, as in that kind of material doesn't exist, but you still are able to follow the logic perfectly
this is some otherworldly experience, wonderful

“This isn’t what brother and sister are supposed to do”

[guytorie]

I got recommended a different video about turning a sphere inside out, and the whole comments section was just saying "you gotta know the rules of the game" and "don't tear it or crease it" so I had to track this video down so I could know the rules of the game

[LethalChicken]

There are two types of people:
Those who saw the original first
And those who saw huggbees' version first

[hotelmario]

Mathematics is basically the closest human beings can come to doing actual magic

[belosneshkaaaa]

this is one of those videos for me where i thought its going to be a confusing and boring video but instead i find it very interesting and i kinda understand whats going on lmao

Reading through the comments, it's makes me incredibly happy so many people share my love and nostalgia for _Outside In_ ! With the recent influx of views, I am going through and reading/liking all the comments as best as I can. If you haven't yet, please check out the description for more resources! If you have any questions regarding the content or recommendations on what I should upscale next, please leave them in the comments and I will get back to you! Thank you!
