The meaning of pi
Your name in PI
Ohh, I can search my name on PI ...
And, will be IMGUT on Pi?
Yes :-)
And I'm the second person to search that .... Who the duck was the first???
No ....... It can't be he .........
...
Duck you ....

Yeah but its not actually useful for any of that shit because there's no way to extract that information. You'd never know which number.
NorwayRat
Or he could have just said you need pi for calculus, and you need calculus for bloody everything
IAmArthurKingOfTheBritains
This is why George R.R. Martin takes so long to write his books he searches PI for the contents of the next novel

frjackhackett
he's talking bollocks and he's evading her question anyway.. i can tell you what pi's good for, getting a good deal on pizza, i use it often
footfoe
Its not some magical number that unlocks all knowledge. Its just the ratio of a circle's diameter to its circumference.

Gotta love Person of Interest...
DMmeYourRecipes
I upvoted for PoI, even though you had cera in there.
knowngnomes
This show is so great. I almost overlooked it. So glad I didn't.
tyrunn
Person of Interest is one of the greatest shows on tv
Varides
This is stupid. You would need 26 completely independent numbers to represent the alphabet.
dmurphthedogg
translate it to binary, translate to alphabet, like computers do

Wow. Not only was his speech cool, but then your post went further! I like you OP, you improved my monday
KarlaAnne
But why did she call him Mr. Swift? That's quite obviously Benjamin Linus.
LiterallyAnOpossum
The only numbers I can associate with whatshisname are 4 8 15 16 23 42
flamingflamingo
[citation needed] There's no actual proof that pi contains every single combination of numbers. It's just a supposition.
Rivalyn
That's a bullshit answer for why pi and the concept of pi is important and useful. I wouldn't have accepted it as a kid.
DancingPanther
+1 for no stupid 1.5 second gifs
schopier
The decimal expansion for 1/3 cannot be found in pi. Your move hollywood math man.

Person of Interest season 5 needs to start ASAP, one of my fav shows
549842694876384225
also waiting for it. wanna know what happens to the machine
NameUser10
Nah
PortgasDAce
It's getting cancelled. :'(
TwoSeamer
No. Nope. No. NO!!!! get it together. NOOOOOOOOOOOOOOOOOOOOOOO. *Micheal Scott NO gif*
IStirControversy
I was thinking about starting it, is it addicting and binge worthy?
daveypavey
Yes, I'm currently binge watching it. There's a lot going on, but it's totally worth it
eightythousandandeightyfive
Yes. Starts a bit slow (very procedural), but pretty much gets better every season.
TwoSeamer
Soundtrack is also pretty dang good
skidbladnir31
Look up Kolmogorov's theory on randomness. Basically it states that a random number is one where the simplest way to express it is simply1/?
skidbladnir31
Writing it down, but since pi could contain any number, it would be simpler to say a particular 50 digit number is digit n of pi to n+50 2/3
skidbladnir31
I'm probably botching it with my explanation, but look it up.
Shamorza
Botching??? Dude, you just raped my mind. As far as I understand any infinite, random string of numbers can contain any combination, period.
IWasInsufferableIn2017
If the k-digit number x is found starting from the n-th digit of pi, then n usually also has about k digits.
IWasInsufferableIn2017
So basically pi is just about useless to compress numbers, and the only sort of numbers you can express shorter this way are the numbers
IWasInsufferableIn2017
you get by taking a (longer than late) sequence of digits of pi in the first place.
damionmauville
But I checked the username...
UncomfortableTruths
It doesn't matter anymore....
saintbrun
honestly... it really wasn't badly photoshopped. Was it?
moxymox
Hell, I blocked the fucking username.
CitizenPrime
Can you do that?
PRND321
I scrolled allllll the way back up, and was sadly, disappointed.
joeycools
Ditto. A little disappointed.

Good one!
bonjbop
It's WIENER anyways, not WEINER.
EroticRhinocerous
I before E except after W
bonjbop
It's a sausage which comes from Wien originally, capital of Austria. It's the name of a place. So it's a Wiener, a sausage from Wien.
TimeFoDat
Stupid scene. What's π good for? Calculating the area of a Pizza to see which size gives you the most pizza for your dollar. You're welcome.
DMmeYourRecipes
It's actually a pretty powerful scene.
TimeFoDat
It's good writing, good acting. It's not good math.
DMmeYourRecipes
Yep. Agreed
TimeFoDat
FYI it's πr^2 meaning take the diameter of the pizza, cut that in half, multiply it by π and then that by itself. Boom, area of your pizza.
toadlily
Except you don't even need pi for that. It's just a proportional constant, as is the ratio of diameter to ratio. Just square the diameter.
TimeFoDat
Ratio of diameter to ratio? I think square inches is easy to consume for most people. What does D^2 produce?
toadlily
π(d1/2)^2 / π(d2/2)^2 = d1^2 / d2^2
toadlily
If you're comparing a 10" pizza and a 12" pizza, you could compare 25π and 36π. Or you could compare 100 and 144. Same ratio, easier math.
TimeFoDat
But what do the #'s 100 and 144 represent? A 10" pizza is 246 sq. Inches, a 12" pizza is 355 Sq. inches. Add price & you get Cost/sq. In.
TimeFoDat
Yes it's the same ratio but in one case we just have numbers to compare & in the other we have price/sq. in. which is more accessible.
TeleDildonics
Math is great but he still didnt give any real reason that it could be of any real use to his syudents. He just gave an interesting anecdote
Schmuck4hire
I was just thinking the same...
CorneliusCardew
I think it's because it's part of the show, he was almost explaining the plot in a way
thefatlonelyjew
yeah. I was thinking about this in the car the other day and got irrationally pissed off
schopier
I agree. The definition itself is why it is important to the students. None of them will ever realize that though...
cocoakoumori
tbh starting with a statement like that seems like a good way to get them interested in Pi and then it's actual practical uses in maths...?
rhinostone
Aren't these kids a bit old for their first encounter with pi?
TeleDildonics
They look to be about 30, so yes lol.
GlitterInTheDarkNearTheTannhauserGate
The genius kid's compression algorithm is based on pi, ie finding files encoded as decimals inside pi and storing index/range
tomyironmane
Every other number? what load of bullshit. Besides, e isn't in there.
tomyironmane
Gunnery. Gunnery uses Pi and Pi derived quantities all the time. Calculus is all about the Pi.
dynamaux
Not sure how useful it is in real life either but here it is explained a little better:
v
Irishda
I always tell my students that ask that the point of knowledge is not "when will I use this".
tomyironmane
And thus you fail. There's shit they teach fifth graders that is utterly useless till you get to college, slog through calculus...
tomyironmane
... linear algebra, multivariable calculus, and get to differential equations. Only then do the numbers i and e make sense.
eraser1
Thing is, you learn so much during those courses, it's best to get used to "i" and "e" sooner rather than later.
tomyironmane
oh believe me, I know. I'm just saying that there are good reasons all over the place; we don't have to dismiss or deflect questions...
gewalt
because its not useful. usable, yes, but useful? not to the general public.
CrissCross35
It really depends on what they'll study, they could easy use it in something school or work relation.
JhericFury
It's useful to help you work out the amount of pizza you're getting per inch, e.g. why a 18" pizza is much more than two 9" pizzas
Corrodias
As much as I love maths trivia, gewalt is right for 95% of us. The act of learning it and studying maths may hold some value, though.
Corrodias
I can't say I've had to do any calculations with Pi since I've left school, but a basic knowledge of geometry enriches Numberphile videos.
Gwego
"Not repeating" doesn't mean every sequence is in Pi's digits. The fact that every sequence can be found in pi is still an open problem.
LaBix
Well I found my service number. So I can be a nerd at work now.
LaBix
Couldn't find my phone number though.
hardytardigrade
Correct.
GlitterInTheDarkNearTheTannhauserGate
It's normal enough for practical purposes. E.g. turn a file into decimal and find parts of it in pi, then send the index to another comp >
GlitterInTheDarkNearTheTannhauserGate
And now the other computer just need to calculate the actual values from pi, combine all the parts together, voila super compression
IWasInsufferableIn2017
That's great until you realize the index is usually just as large as the file itself.
GlitterInTheDarkNearTheTannhauserGate
That's where I gave up the project :) there's an implementation out there though, pi-fs
AvielMenter
I was hoping somebody had left this comment. We do know some numbers that are normal; pi is not one of them.
dmurphthedogg
Actually, we know that almost every number is normal, it's just hard to give concrete examples, my fav: .1234567891011121314151617...
AvielMenter
That's a bit of an obvious one.
dmurphthedogg
normality implies each string of digits occurs with correct frequency (look up actual definition if you'd like) which is much stronger
MuscledStickInsect
Pi is infinite and never repeating so every sequence AS to be in the digits even if we don't know where it is (=>open problem).
Mmxikus
Nej. The amount of possible sequences is still infinite, even if you skip a few. Even if you skip an infinite amount.
BitchButcher
How can infinity be finite?
hardytardigrade
Not so. This sequence is infinite and never repeating: 0.121122111222111122221111122222... but there are many sequences it doesn't contain.
MuscledStickInsect
Pi has no logical sequences in it's digits.
hardytardigrade
1) That wasn't the question being examined. The point is that there are infinite, nonrepeating decimals that don't contain every sequence.
hardytardigrade
2) So how do we know that pi is not one of those? From what I am reading, this hasn't been determined.
MuscledStickInsect
Ok you got the point, I admit it :)
