this video is going to be a little more educational than usual
OK, so there is this channel that I used to really like watching called Vi art
Hart. Heart?
And I say 'used to', because she doesn't really post that often anymore
She makes videos that combine two of my favourite subjects: Math and Art.
y-you like math???
Yes, okay, I like math.
So vi hart (I don't know her real name)
made videos about math, and triangles, and trans-genderism...
I'm gonna be honest, I've kind of forgotten everything she's talked about
hexa-something, that was one of her things...
but every year she's made anti-pi videos
Pi as in the math pi, remember? we're talking about math... not the...
Okay, so she posts them every year on pie day
wich is today, it's pie day, if you didn't know that
let me just tell you something interesting
about pi, in 1949 we started using computers to find pi and we kept
getting closer and closer as technology advanced and we never found the true
value of pi
To this day, all those PI to a million places websites
Nope, not pi. Yeah, we've gotten really really close to PI and yet we're nowhere
near as close because it's infinite
I mean it's close enough where you physically can't measure that accurate
in the real world but it's not the true value of pi. The true value of pi goes on
forever and we haven't really gotten to the end of that
Okay, so back to vi hart. there's a high chance she made a 2016 anti-pi video
today right now so go check it out link is in the description if she's made one so
I guess this is a rebuttal video about why pi is actually awesome but I'm
going to be rebuting her 2014 video, because the 2015 one was kind of stupid
"Ah, March 14,
That's just an arbitrary number on a calendar we created Yeah!"
Man, shut up and I actually wanted to make this video back in 2015
but I didn't instead I just made this comic because last year was hashtag
ultimate pie day. So I've actually waited a year now so I'm excited to talk about it
Let's do it!
I hope i'm not breaking any copyright laws by this. "Pi day, I'm mad about how people
worship pi for being infinite for going on forever
first of all pi is not infinite"
Well yeah it is but that's not why it's awesome every number is technically
infinite you take the number four and you add a point zero
for still the same but in theory you can add a zero forever making it technically
infinite and that's just what PI is. it's just a number
it's not infinity. no one's saying that it is. "I know it's not about its
magnitude it's about all those digits infinite digits going on forever but
first of all it doesn't go anywhere"
Yeah, no it doesn't. That, *sigh* it doesn't make it not
awesome it's right there on the number line between three and four
it's just a number like I said, y equals pi is just a straight horizontal line
you take the derivative of pi - you get zero, it's a number! It's just a number man, just a number!
"Pi is a number, not a process"
Yeah, okay, we agree! but that doesn't make it not awesome
the speed of light is "just a number" it's about what that's super specific number
represents
"Secondly yeah so it's got infinite digits, so what? One-third has infinite digits."
Yeah but pi is random numbers that go on forever and
there's no pattern, that's what's so cool
do you know what the trillionth digit of pi is? No! No you don't, it's random digits
with no pattern. but I know the trillionth digit of one third - spoiler alert -
It's three!
"There is exactly as many digits in one-third as in pi as in 9.9999 repeating..."
Yeah the digits of pi are random but the number as a whole
isn't random at all, which is another cool thing.
It is the ratio of the diameter of a circle to its circumference,
multiply the diameter by PI you get the circumference.
Are you forgetting that?
"There's an infinite number of irrational numbers.
For any two fractions you can find another fraction that's between them, and again and
again and again - there's never any fractions that are right next to each other on the number line."
Yes, irrational numbers are technically everywhere
take the one millionth digit of pi, change it to a three and you get an
entirely new irrational number it's not pi anymore
I mean this was never pi to begin with, but you can't use this to get the
circumference anymore
nuh-uh, not good. but it's this highly specific irrational number that this special ratio occurs
Not this one, not this one, this one!
It's why we made this specific irrational number its own symbol
Well okay, we actually used a Greek letter so it's not totally made up
"So, I don't know why anyone would make a fuss about the grand infinities and
forevers of a boring little number like PI."
*scoffs* It's not boring
number by taking such a simple ratio of such a simple geometric object."
Yes! Thank you! It's so weird right?
"Surely that never happens with other simple ratios of other simple geometric objects - OH WAIT! They're in everything!"
What? No, okay. If you take one of the sides of a square and multiply it by this number
you get the length of it's diagonal between the corners
Ok so this is the ratio of the side of a square and its diagonal
and it's just random numbers that go on forever kinda like pi.
So why don't we celebrate this number? Why don't we have a special symbol for it like pi?
Well, actually we do! It's called radical 2!
Look, you just take this number, you square it you get 2! Just plain, old, boring 2. That's not special!
You can't square pi and get something like 10!
You square pi, it's still irrational! Look at this triangle same deal right?
This number goes on forever - but wait - it can be written down as radical 3 over 2
just like what you did in the video! Now this one for a Pentagon we do use the
symbol for it. It's a Greek symbol called phi. phi. phi?
That's really close to pi. I wonder if that was on purpose... now phi is approximately
this number
kinda like pi right? Totally one hundred percently irrational
I think we got ourselves another pi - but wait we can rewrite it like this!
Hey, sidenote; this number is considered to be the golden ratio it has to do when we talk
about that swirly like seashell thing and it can actually found an art so that's
pretty cool
Okay, back to pi! You can't rewrite pi like any of these numbers, pi is its own
number!
It stands by itself above the rest it's not radical 2 not rad 3 over 2 but just
plain ol' 3.1415
That's why pi is so awesome. there's a picture going around the internet that's
like pi contains the day you were born the day you die
we give the numbers letters every possible conversation you ever had and every
conversation you didn't have. You see now that's just stupid.
that's just the nature of having random numbers go on forever.
I could do the same thing on random generator.org if I just generated a
random digit forever
Now what does this mean, do circles even exist?
How can you have a bendy line with just straight lines? What is real?!
Alright so just to finish things up this is all bull crap.
Well not all of it... Well yeah, all of it. The reason why pi is actually famous
and so beloved is because let's be real guys
it's called pi. you don't see people celebrating pi day because they
appreciate how this irrational number is the ratio between the diameter and the
circumference.
They're celebrating it because it's called pi!
"You can't tell me the success of Kevin Bacon isn't somehow tied to his name.
You're not going out to see a Kevin hot dog movie."
And I think that's what happened to PI.
People were like, "Ahh this boring math term has a funny name!"
*Snicker*
"Let's celebrate it on our meaningless calendars."
... That was a video... vi hart, I don't even know if you go on the internet
anymore but I used to really like watching your videos because you know
when I was like growing up. I've, I grew up with you. I grew up with your videos
I know you, you know? vi hart if you're watching this
what's up I used to really like watching your videos you should make more
I miss you. Your'e alive, right? No, you are alive. You have a twitter. I... I follow you on
twitter
Please come back! They only have reaction channels now and they're stupid! *sniff*
