It's a Baker's digit!

For me though, the video came out on March 13th, not March 14th!

@@sdspivey then 0

Good for you. For many people it's the opposite

Yes

Seconded

Shaped the person you've become? is it triangle shaped perchance?

I've only just stopped making hexaflexagons. Finally she's uploaded again!

Ah so cute :)

Is that shape a triangle?

sounds like pizza

I bet the universe is cupcake shaped

Yass

Now I'm worried that some pizza chain will start selling Fruit Filled Circley Crusts and Vi will receive no royalties. Quick, Vi, file a trademark application before Domino's sees this video!

@@LilythathappenstobeinaValley Please, _fruit-filled_ circley crusts. Who would _ever_ put something like a pineapple on pizza?

Same, definitely feeling like I’m missing something here

Vi is making a case that 12 videos is enough in this series and that they are planning to end the pi day series, which is sad because vihart content is always super enjoyable but also understandable because they have been doing this for so long now!

​@@non-pe8xn but she made a 13th video...

For me it is theory vs. practicality, and how maths can go on crazy theories and tangents when sometimes all you need is 12 digits of pie

We all have listened to Vi's lecture thinking 'this is non-sense' but unfortunately We are actually missing digits of pi :O That's right those "...." at the end of our expressions of pi are the real missing digits of pi.

Insanely massive W son W life W you

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.

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

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

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

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.

This series is over, but the channel is not.

@@plushloler But there's nothing on the channel anymore except that series...

@@viliml2763 which means that without this series Vi can start doing other content.

@@plushloler - That's an odd take. You make it sound like Pi Day was constraining Vi, rather than it simply being an incentive for Vi. What makes you think it's the former and not the latter? As far as I'm aware, and I admit this involves some amount of conjecture, Vi is happy not making a living on RU-vid and simply makes videos when inspired. Pi Day was once an inspiration and perhaps now it's not. Why would that suggest a new inspiration?

Pi day sucks anyways. Celebrate Tau Day instead.

Happy Birthday! :D

Hap Birth

Happy Birthday!

Birthday twins!

Happy birthday!

Omg is that why it's Pi day in the US? I never noticed that with my DD/MM/YYYY

Vihart is not the only person I've fallen in love with without ever meeting or truly interacting with them (I miss you, Lindsay!), but she is the only person I've ever fallen in love with without ever meeting them AND without ever seeing what they look like. ♥♥♥

@@MilesDashing 👀👀 yikes... parasocial much? Like, i get what you mean-- 7 years ago, in middle school, I was crushing on Vi too, but LOVE?? That's a bit much... its a lot much ;;o-o go outside lil bro

Elsewhere it could have been 22/7. ;D

Surprised no one said "Hi Cary" this time, lol But yeah, the lore is expanding, and we need to try to keep up, or else we will be left in the dust of irrationality

@@Smams19Ha, fool. You were now the one to say "Hi Cary"

Bye Cary

That's rich for you to say. Circle.

I love how this is edited but is still spelled wrong, haha

What does THR sound sound like?

THR KING

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.

Mine too! Happy Birthday!

Happy birthday, Kat!🎂

Happy Birthday Kat

Hey nice!

I believe Albert Einstein was also born on this day. I'm jealous.

Vi Hart is like the TI BASIC programming language on your TI-84 calculator. It isn't super intense learning about maths or programming, it's kinda useless, but also, it helped you get over that hump of misery that is middle school and fostered a lifelong and willing exploration of STEM. Vi Hart and TI BASIC both hold a special place in my heart.

Except they made 13 videos on this series.

​@@masterYoshimistsu how about 12 in the series, 1 on the series?

She said "happy pi day," so it must be part of the series.

I really hope it isn't actually the end, though I totally respect if it is

So the 12 is totally arbitrary then right? Other than one for every month of the year I mean? "Science" hasn't in any way actually suggested pi is well apporixmated by 12 right?

oh nooo...

Yes what a wholesome and perpetual tradition that I love 💛💛 (Also thank you so much Vihart! You've done so much already, you deserve a break.)

... to say she wouldn't be returning in this way again

I was reminded of pi Day when I saw Matt Parker's video a couple days ago

Try varying time signatures

lol

I think I'd trust Triangle to know a thing or two about √3

I’m so early I found one of my favorite youtubers in the comments (Hi from a patron!)

oh hi lily! cool to see you here

it's not *real* real, as far as I can tell, it's an extended metaphor that she's only doing 12 videos pi does have more digits than 12 though

@@rubylandau-pincus5490 omg hi Ruby, i'd know that name anywhere!

@@hexeddecimals hi! :)

I can't tell whether it's even a metaphor or not

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

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

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.

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

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.
