    ----UPLOADER NOTES----
    Given it's relationship to Outside In, I figured it was only right that I upload Not Knot as well. I have an original VHS and supplemantary book of Not Knot, if anyone has a legit VHS copy of Outside In please let me know! I opted to use the DVD release for the upscale, mostly because I don't have a VHS player to record with but also because I'm afraid I wouldn't be knowledgable enough to create a high quality rip from an analog source.
    My upscale skills are pretty basic, what I've excelled in so far is digging up the highest quality originals to upscale from. I'm getting better at command line arguments for a lab I'm in, so hopefully I'll be able to start upscaling using Joel Hruska's DS9UP methods.
    I plan on doing more upscales in the future, if you have any suggestions, please let me know!
    ---DESCRIPTION---
    Not Knot is a guided tour into computer-animated hyperbolic space. It proceeds from the world of knots to their complementary spaces -- what's not a knot. Profound theorems of recent mathematics show that most known complements carry the structure of hyperbolic geometry, a geometry in which the sum of three angles of a triangle always is less than 180 degrees.

    Supplement to Not Knot
    Written by David Epstein and Charlie Gunn, this book offers in-depth explanations to the concepts discussed in the video. I have a physical copy of this book, but I have yet to find a copy of it online. Archive.org doesn't appear to have any listings for it, and all my search results end up with unrelated content or used physical copies. If you are able to find a digital scan of this book online, please let me know and I will add it to the description. I don't imagine this video getting many views, but if there is great enough interest I can contact my university's library and see if I can use one of their professional scanners to upload my copy to share.

    A string walked into a bar and ordered a beer. Bartender says "Get out of here, we don't serve strings." This happened a few times. The string had an epiphany: He tied himself up like a bow in a shoe and walked into the bar and ordered a drink. "Get out of here, we don't serve strings" said the bartender. Said the string "No, I'm knot". drum roll and cymbals

      I would recommend Arnaud Chéritat (th-cam.com/channels/zp3-A4cjdNmeYzeTCdK1FA.html). He is a French Mathematician who occasionally posts topology videos online )
      Additionally you might also be interested in 3Blue1Brown. The following is a link to one of my favorites, "Who cares about topology? (Inscribed rectangle problem)" (th-cam.com/video/AmgkSdhK4K8/w-d-xo.html)
      And finally, if you haven't watched it yet, there is also _Outside In - How to turn a sphere inside out_ , that I've shared on my channel. It's my absolute favorite math video.
