Extended crochet video at www.patreon.com/posts/116050981 More knot videos: kzbin.info/aero/PLt5AfwLFPxWLyfD4nhZCX_3UZdSSpkBTs

[@SwapnilKachhara]

I'm sure half of this went over my head but I loved it all the same

[@runristaren]

Ruined No-Knot-November for me...

[@rosiefay7283]

Not just no-knot but no-knot no-knit November, as well.

[@idontwantahandlethough]

lol I love the weird corner of the universe that is the intersection between knitting and mathematics. Who would think they work so well together?

[@Ta2dwitetrash]

Current /flow. Everything does it.

[@LonkinPork]

I can't explain exactly how or why but from the thumbnail I expected this to be an Ayliean video I was surprised twice!

[@moe_dk]

@4:30 this week I learned that not everything is named after Euler, Euler found Lagrange point L1-L3, yet they are not named after him.

[@ahvavee]

I love knot working!

[@pickledlampshade]

Misleading title it is a surface

[@christopherlawley1842]

I see what you did there

[@vikaspoddar001]

Yep

[@idontwantahandlethough]

YOU'RE A SURFACE

[@alcodark]

no it's knot.

[@Ta2dwitetrash]

Knope

[@Ta2dwitetrash]

The fact that it can be perfectly made using crochet speaks volumes about the universe.

[@rhoddryice5412]

Do knot forget to like and comment.

[@zanedobler]

This is crazy, I *just* watched Henry Segerman's video on Seifert surfaces last night.

[@Lamb666]

I’d love a video explaining Scott Steiner math. One of the best to come out of the University of Michigan.

[@chrisschryer]

Everybody should have somebody in their life who looks at them like Ayliean looks at Sophie.

[@Ana_crusis]

I'm quite fascinated with knots and topology

[@S1nwar]

I wonder if there's a stable molecule with this shape

[@colecohen4581]

Like how there are two holes in trousers

[@sh1sh1maru]

Don't dis my man Euler!

[@AmmarShahin]

0:44 Love the palestinian kufiya ❤️❤

[@elekvault]

I swear, the thumbnail had me thinking this was a new Vi Hart video.

[@dannydandaniel8040]

Topology...

[@fahrenheit2101]

I'm knot too sure what just happened, but it was interesting

[@pistachos4868]

Omg, i loved this video, the energy of them is so contagious!!

[@mattparker-2]

Mobius Strip? Boring. How about a Mobius Sphere?

[@E1craZ4life]

You mean a Klein bottle?

[@theflaggeddragon9472]

Real projective plane

[@mattparker-2]

reminds me of a mobius strip with just one surface, pretty cool euler characteristic also reminds me of v + f - e = 2 for connected planar graphs

[@TristanFrodelius]

The "figure-eight" knot is also called the Cavendish Knot, which is a better name, given that the "figure eight" form of the knot isn't an intrinsic diagram of the knot. And the use of the name "figure eight" tends to make people mistakenly think that the figure-eight shape is unavoidable of inherent to a diagram of the knot. In fact there is a much more intuitive and visually simpler and _symmetric_ diagram of the Cavendish knot that can be generated as an epitrochoid with a rotor of half the radius of the stator's, and a drawing radius greater than their combined radii (using the stator's diameter out from the rotor's circumference is particularly satisfying). I think that it's worth knowing that what people often _call_ a "figure eight" knot doesn't have anything to do with the number eight, and in fact does have a more intuitive and symmetric and elegant diagram. The almost prescriptive perception of the knot (my favourite knot, for what it's worth) is kind of disheartening. That's why I prefer its more traditional/historical name: The Cavendish Knot. It's at least a less biased name.

[@macleadg]

Great video, but it only scratches the surface of the topic… 🙄. (Ok, I’ll leave now.)

[@MinistryOfMotivations]

Focus on your purpose, start with small actions, and remind yourself why you started. You've got this.❤

[@ucngominh3354]

hi

[@simonsaville9962]

Congratulations! You've made some uncomfortable looking underwear. Infinite underpants anyone? Marvellous, thank you ladies.

[@Ta2dwitetrash]

Lightspeed Briefs™! Now in 2 designs: Mobius support strip™ and the Infinite comfort knot™

[@ibrahiymmuhammad4773]

Awe lol

[@ibrahiymmuhammad4773]

Hahahaha

[@TiagoMorbusSa]

uwu?

[@radadadadee]

0:44 ...aaaand I'm out. Bye.

[@kygrus]

shush

[@Nebukanezzer]

Triggered little snowflake getting upset at somebody with highlights! Sad!

[@maxine_q]

This is not a train station. You don't have to announce your departure.

[@AmmarShahin]

Sure zio 😂

[@CommenterMeow]

First like and comment

[@jbtechcon7434]

This is what's called infantilization.

[@SlipperyTeeth]

Smart baby?

[@TiagoMorbusSa]

I think the word you're looking for is "misogyny"

[@idontwantahandlethough]

I think you're reading too much into things. Plus, babied can't knit. They'd poke their eyeball out!

[@clangerbasher]

Oh, get knotted.

[@landsgevaer]

You seem to imply there is something wrong with that? Adulteration is where the trouble starts.

[@Humblemumble7]

What in the "all inclusive agenda" happened to this channel?

[@ADavidJohnson]

are you angry that women mathematicians exist

[@Humblemumble7]

@ADavidJohnson Well, that's certainly extreme, no? Blowing up what you believe I said to its most incorrect interpretation? That's the most base level of "getting" someone.

[@hammerth1421]

Mathematicians are quirky people? Colour me shocked!

[@fahrenheit2101]

More like who hurt you? Are you insulted by the existence of these people or something?

[@fahrenheit2101]

@@Humblemumble7 Nobody took what you said to any extremes, you did that on your own by watching a perfectly normal video and somehow finding a way to complain about inclusivity. It is genuinely difficult to come up with ANY interpretation that isn't wildly bigoted in some way.

Under 8 seconds.

[@DeepeshMaan]

Just when I thought I had my life together... knot theory comes along and shows me how tangled everything really is. 😵🪢
