We did it! New video! Mugs! Bagels! Peachy Rings! Toroidal Graphs!

#3 on my "what videos can I make quickly" experiment is response/puzzle commentary, in this case in response to this collab by 3blue1brown: https://www.youtube.com/watch?v=VvCytJvd4H0

What I learned is that this kind of video is not a 1 or 2-day video, it is a one-week video. The script was fairly quick to write, but not as quick as Spidermath because SOMEONE just HAD to try to actually explain things and demonstrate things and tell at least a little bit of a story, and then there were materials to source, and lots of filming time because SOMEONE decided it was a good idea to draw all over a bagel and peachy rings and mugs and paper and everywhere.

So, I like the video but it doesn't fit the "what can I do fast to leave time for longer deeper work" plan. Lessons learned, and that's why I'm experimenting with a bunch of different things this month!

I also always underestimate the time it takes to upload, assemble thumbnails and descriptions and links, double-check my sources and references and titles and tags and captions, social the medias, post the posts, etc.

But this week has some great links and references!

Susan has also collected a page of other artistic renditions of the 7-color torus and links to instructions for beadwork, fiber arts, and other further reading: http://faculty.smcm.edu/sgoldstine/torus7.html

Honestly, mathsgear has some cool stuff. I know I should be selling and promoting my own merch but I've been a little busy drawing on bagels.

But, we did put in the order for the Tau Day shirts last week, so they're at the printers and should ship out by the end of the month. We ordered some extra which are still available while they last: https://store.dftba.com/collections/vi-hart

Ok, I'm gonna post the post now!

But I Love your OCD cuz it makes mine feel 'special'. Will do puzzle later CUZ BUS. Your loyal Cuz

Sarah L.

Colored frostings on a bundt cake would be a great video. It could be part of your Edible Topology series (in the spirit of your Flex Mex ;).

Susan Goldstine

Wow! Super honored to get the shout out! Love the video.

Susan Goldstine

For future reference, “Goldstine” rhymes with “line,” “wine,” and “affine,” not with “Diophantine.”

vihart

Thanks for the torus! Let me know if there's a better link for full instructions and I'll add it.

vihart

Oh whoops, I meant to double-check that. I'll get it right next time!

Henry Segerman

After all of those "aiyne" words, I don't know how to pronounce "Diophantine"!

Randal Moore

I came up with a bunch of huge loops for the original 2D puzzle. Right? But now I need a nap rather than EVER thinking in the MUG Dimension. Maybe even a long hibernation. Does anyone else feel confusion as 'brain pain'. This obviously hurts me more than it does you. So why do I keep coming back for more? Pavlov's dog? YOUR dog? IDK Nevertheless, I remain fascinated.

Susan Goldstine

There's not currently a better link for full instructions, but they are in "Beading the Seven-Color Torus" by me, Sophie Sommer, and Ellie Baker in the September 2013 issue of Math Horizons. Might be nice to put that info in if people want to track it down.

"So, I like the video but it doesn't fit the "what can I do fast to leave time for longer deeper work" plan. Lessons learned" -- I hope you didn't do this video just because it was supposed to be short. I really liked that video actually, so don't "apologize" because it isn't deep enough, I'm sure a lot of people appreciate that kind of videos.

Arnim Sommer

How often were you nearly biting into that bagel?

Richard Kusaba

Please be kind to that SOMEONE for it is to her that most of my support, Patreon and otherwise, is sent. Thanks.

Thomas Boys

So next step - utility puzzle on a Klein bottle? :D

Kenny Tilton

So you did it?!!! Even more than the challenge?!! I was just listening to your voice and meditating on things like, Gosh, I have never before leveraged the roundiness of a handle. You have given new meaning to "everything bagel", and I am sure you are a fine musician but your gummy chew painting was jaw dropping. I mean, cellos are *designed* to be celloed, but the gummy chew maker never saw you coming. Bravo!

vihart

I have a surprising amount of experience with peachy rings, this skill does not come from nowhere, I promise you! :D

vihart

I definitely didn't do it JUST because it was supposed to be short, I thought it would be interesting and people would get something from it! My hangup isn't about whether the video is deep to others, it's about whether I learn and grow from working on it, and whether a different project might serve both functions simultaneously.

FYI <a href="https://store.dftba.com/collections/vi-hart" rel="nofollow noopener" target="_blank">https://store.dftba.com/collections/vi-hart</a> is not *prominently* linked from vihart.com. It's mentioned in several posts (like this one) and can be found by searching "shirt" — but not "t-shirt" (<a href="http://vihart.com/?s=t-shirt)." rel="nofollow noopener" target="_blank">http://vihart.com/?s=t-shirt).</a> Say you're me and you're looking for way to support Vi Hart and buy merch but you don't know it exists — a link in FAQ or even the top bar would help. Speaking of that, Patreon should be linked at the top bar! Patreon is linked at bottom of Supporters page but if I just landed on your site, I might not realize you're *looking for support* or *have merch* so I'm not likely to click "Supporters" (for all I know it might be as boring as "Acknowledgements" sections, or "This work was supported by grant 1729..." footnotes). ☑ Patreon does link to t-shirts, right from the Overview. ☑ Youtube does link to Patreon. though old youtube videos only link to vihart.com

vihart

This is good points, thanks!
