[@Zosso-1618]

this has the same energy as when my friend and I got into an argument about whether a hyperbola is more circle than a circle or not

[@Jellyjam14blas]

Is it? I don't think so. Because like, even if it was 100% circle, it would only be the same as the circle (Which I assume to be 100% circle), and not more.

[@gaymerjerry]

I mean Parabolas Circles Ellipses and Hyperbolas are special because they are conics aka cross sections of cones and share a lot of properties because of that

[@christopherellis2663]

So, where is the equal distance from the centre? Clever, but not exactly smart.

[@justarandomdood]

Hyperbola eccentricity = c/a > 1 (c always greater than a for hyperbola) Circle eccentricity = 0 Parabola eccentricity = 1 0 < Ellipse eccentricity = c/a < 1 (c is always less than a for ellipse) Therefore, hyperbolas are the furthest you can be from being a circle while still being a conic section

[@sebastianw1980]

You are all fools. The circle, in its perfect homogeneity, contains only itself. It is a failure of a shape, unable to comprehend or even imply anything else. This is why Ptolemy and Copernicus were fools. Uniform circular motion? I say: bah, humbug. The ellipse has two foci to the circle's pathetic one, meaning the ellipse implies two circles. This is better, but still ineffective to truly begin to hear the music of the celestial spheres. Next, take the parabola. It is similar to the ellipse in that it has two foci, but one of them lies at an infinite distance. This implies two circles of infinite radius, greater than any circles inscribed in merely finite place. This is reminiscent of the sphere of the fixed stars, long held as the finest example of "circular" motion like the idiotic Aristotle. If the parabola is more symbolic of the sphere of the fixed stars, then it must comprehend more of what we call circularity than the circle. Finally, ee can move onto the hyperbola. What is farther than infinity? For the second focus of the hyperbola rests at both infinity and negative infinity. This must be our truest understanding of circularity, for not only do the circles comprehend the motion of the fixed stars, but the selfsame focus represents the shape of the earth, which is a perfect reflection of the sphere of the fixed stars, ordered by the demiurge to give us hints as to the true nature of the universe. To argue this point is to reject the will of the demiurge, and labels you a common man not worth even the dirt you tread on.

[@midknight1339]

I'm not sure if I'm interpreting the metaphor here correctly, but it seems as though this might be the end of the Pi Day series. Which is, on the one hand, scary; something which I quite literally grew up with is disappearing. But on the other hand, it's oddly reassuring. This series has done for me (and millions of others) everything that it could. Its work is - against all odds - complete. Maybe someday I'll make my own such series, and know that someday it too might achieve its goals. Thank you for everything, Vi.

[@Ruminations09]

13 years... dang... This series is one of the longest things I've continually watched (on or off KZbin). This might not be the proper forum to express this, but I feel like a lot of my formative years were shaped by your videos. When I was in middle school, your pi videos inspired me to learn more about pi (and tau) which fostered a really persistent love of both math and science that carried through my high school years. In my junior year of high school, you released On Gender, which was probably the first major step in me realizing I was non-binary. Realizing both the ways in which my experience matched yours - as well as the places where our experiences differed - led me to question things about myself that I had taken for granted my whole life. There's not really any good way to properly thank someone for that kind of indirect action - you don't know me, and obviously I know those videos weren't made for me specifically. But they still had a big effect on me and I truly appreciate it.

[@AnonyMous-pi9zm]

On Gender was really the thing that opened my brain to the notion that other people can have a different experience than myself. With gender, with race, with liking or not liking mathematics or art or whatever. Sure, I knew that people were different, but I didn't have a framework for understanding those differences and how it impacts people. Vi implored me be empathetic to other people in a way that my upbringing never really fostered.

[@nattpich]

Most people are saying your videos got them into math but I’m here to thank you for getting me doodling, your videos single-handedly raised my interest in doodles which has now led to art as a career! So great to see you’re still making videos and so glad they’re popping up in my feed again!

[@AllenGrimm1145]

I think 4:44 implies that the reason the measurements come out to 12 digits is because, rather than the universe adjusting itself, Triangle's somehow been "eating" the tiny missing piece of pi out of the universe cone-style each time the Sciences make a measurement to mess with their results (and also to help themself become a circle to fulfil their own side of the bet, although that part doesn't work out).

What is the significance of 12 digits?

[@beretperson]

Wait, is it really true that in the physical world, pi can't be measured beyond the 12th digit?

[@Caterpie56]

It only has 12 digits, how could you measure more things than there are?

[@hexeddecimals]

it's true to some amount of digits that there's a limit to the precision of pi's measurable value, but I think vihart only chose 12 because she's done 12 (now 13) pi day videos

[@52flyingbicycles]

I’m going to say no, though 12 digits would be an insanely precise calculation. Let’s say we have a perfect circle, with a crystalline structure accurate to the atom. Atoms are about 100 picometers wide, so they are our limit to accuracy. There are 1E10 of those in a meter, so 10 digits of pi. To measure 13 digits of pi, we would need an additional 3 orders of magnitude, so our circle would need to be over 1000 meters around with precision down to the atom. However, we can measure pi indirectly through the physical constants, which we have extremely precise measurements of.

[@kyle-silver]

I also wonder if it’s a puzzle, as in: what system of mathematics is there where Pi isn’t irrational? And that would be a “universe” that uses a different definition of distance, something closer to a Manhattan distance

[@TheBasikShow]

To accurately measure the circumference of the observable universe in Planck lengths, you need about 62 digits of pi. So, that’s an upper limit to the amount of pi that could even be measured in principle. To accurately measure the circumference of the earth in millimeters, a much more reasonable value, you only need about ten or eleven digits of pi. Twelve is more than enough. If using a high-tech laboratory with electron microscopy, accurately measuring a meter-wide circle will also need ten or eleven digits. So yeah, 12 digits is a reasonable limit for how measured a circle could be on Earth. Keep in mind, though, that the actual difficult part of measuring a circle in the real world is creating a perfect circle in the first place. All of this business about how much precision would be needed if we did have a perfect circle is just silly fun.

Vi, I have been watching your videos since I was really young, something about those old L-Rules videos with turning simple lines and turns into complex shapes used to amaze me. Today I made an L-Rules generator to make procedurally modeled plants, and I'm so happy. Thank you for all the work you've put in and for the inspiration you've brought to me and countless others. Happy belated pi day :)

I watched your pi day videos every year growing up and now I’m in college. Thank you for all the inspiration 😊

My 8th grade math teacher showed a bunch of your videos in middle school like 9 years ago at this point, and I still think about these every pi day

Omg girl I was thinking about your channel and went looking for your stuff. I used to love this channel as a kid. I absolutely love your stuff and I'm so glad to see you making videos again

This is such nostalgia when I was like 9 or 10 I watched you for the first time about hexaflexagons and I loved them so much. I wait for this video every year.

I used to be shown your videos in class when I was in elementary school, and now I’m going on to graduate in a STEM field. Thank you so much for making math fun! (I still make hexaflexagons on occasion :) )
