How pi was first calculated

[GRMEGISTOS]

LOSER...

[DiogeneCore]

@GRMEGISTOS You're looking intelligent, very useful comment, great! Thumbs up for another retarded!!

[ssusulic79]

it was because he mesure 22 cm with ruler,aproksimately,not exactly.

r=3.5 cm , so O=2r Pi=2*3.5*3.14=21,98

but if u do it with Pi = 3.14159265... it wil be O=21,99114... so O/2r=21,99114.../7=3,141592654­...

First Pi was calculated aproximately,which was good cos we still used 3.14

[ssusulic79]

This is so stupid...

It's 22 / 7 = 3.142857.... O=22cm , 2r=7cm

It is done by some guy(can't remember his name) who roll circle (diametar 7 cm) on the table,then mesure it and divided...so simple

[geotk91]

@ssusulic79

Pi=3.14159265... not 22/7=3.14285714



[rotten25000]

cool



[rotten25000]

@rotten25000 creepy... but cool

[elflordbob1]

or you just divide the circumfrence by the diamator

herp derp

[Countlouis]

@elflordbob1 thats what the video tries to show you..how many times the circumference fits into the diameter

[drkenun]

@Countlouis how many times the diameter fits into the circumference, you mean :p

[Countlouis]

@drkenun oops! :) you're right! thanks :)

[drkenun]

@Countlouis you're welcome, and thanks for the video. it helped me explain pi to my teacher's class.

[Countlouis]

@Countlouis *I'm sorry I meant the diameter into the circumference

[sharpjaws]

@elflordbob1 how dose he divide circumference if he didnt know Pi ?

[elflordbob1]

@sharpjaws

takes a peice of string and wraps it around the circal tehn measures teh string

..i am serious

[jrinkthedew]

@elflordbob1 Read the title herp derp

[4tpride]

@elflordbob1 - of course! That is an obvious statement. The circumference requires pi; C = 3.14 x D, so if you divide the circumference by the diameter ((3.14 x D) / D), you will be left with 3.14. This occurs the same way as if you have the number 5...if you multiply it by 4, and then divide it by 4, you will be back at 5. This video is attempting to dig deeper at the origin of pi. Respect.

[sykkix]

The last digit of pi is "4"

[elflordbob1]

@sykkix

pi is an irratuinal trancendecent real number it has no ending 3.14 is the approximation

[ridoymonie]

I LOV MATHS

[stiffex]

Pi is a static calculation of a circles infinity & can never be divorced from Phi in the phenomenal world....

[ROCKNintendoYO]

1120 digit estimate (last few numbers) : 59

[ROCKNintendoYO]

When a circle's diameter is 1 unit, its circumference is π units. So you can't use a bigger circle. The scale shows how the units are measured, so you have to use this size to calculate π correctly.

[Countlouis]

@ROCKNintendoYO The unit 1 represents the diameter which could be 1 yard or 23 inches or any other size. The video shows how many times the diameter fits into the circumference, no matter what the diameter is, the circumference will always be 3.1415.. (π) times the diameter.

[tybash]

Who wants some pie.

[spymat6]

do it with a bigger circle.

[danielbarragan87]

my balls are pi yay!

[pizzaguy553]

the last digit of pi is...PIZZA!!! yay pizza!

[RaceOfAce]

Isn't pi just the circumference of a circle divided by its diameter? Honestly this video makes zero sense to me.

[kingofdice66]

@RaceOfAce wroooooong

[Greshney]

@RaceOfAce First U must find the connection between Pi and circle... It did not pop out just like that from the paper. Let us take the diameter of a circle for a simple unit. When you open the circle it's lenght is going to count 3,14... units. NOw we got a conection, a number and also a path to try to prove it mathematicly. :)

[fnorgen]

makes sense to me.

[LizzyAston]

how does it give pi, when the diameter x 4 is used? i would have thought it would equal 4 not pi...

[EclecticSceptic]

@LizzyAston Ok look at the beginning of the video. The circle rests between the 0 and 1 markers. Therefore the diameter is 1. If diameter (=2radius) is 1, the circumference is pi. C = dpi = 1*pi = pi.

[dante2k8]

Chuck Norris knows the last digit of pi

[ba3cool]

@dante2k8

Correction: Chuck Norris IS the last digit of pie

[TheForgottenMarioBro]

@ba3cool Chuck Norris is not a number. But Old Spice Guy is.

[alinusD]

@ba3cool Correction : Chuck Norris IS the last digit of PI

[ba3cool]

@alinusD Lol, I caught that one a second after I hit the post button.

[ypi314]

@ba3cool Correstion: Its pi!

[ba3cool]

@ypi314 Read my previous post!

[Robolawrence23]

@ypi314 correCtion

[apskeller]

@ba3cool

So, let's eat him then... ;)

[PiEndsWith0]

@dante2k8

Chuck Norris is all digits of pi

[stellaruniversexmpls]

@dante2k8 The last 2 digits are ...68.

[nasdin94]

Ah i see, its how many sides a circle has.

Its the same as replacing those circles with identical squares; a line of squares then "rolling out" 1 of the identical square, Then you'll get a value of 4, identical to the amount of sides a square has. Doing the same method but changing it to a circle would find the the amount of sides a circle has, which is Pi

[DeWinds]

I don't get it. Doesn't it depend on the size of the circle?

[News101r]

well kinda you use the circles diameter (the length of the circle going across) as the amount of space beyween the numbers like if i had a one inch circle its diameter is one inch so i use that then do what he did there to find the lengh of the circumfrence

[LizzyAston]

@DeWinds nice logic there. have you gotten smarter over these last 6 months?

[DeWinds]

@LizzyAston

I'm afraid I don't understand you.

Sweet app.. works great! I downloaded mine at androidanchor,,com

[guit4rmaster]

@C2aimar123

What is this? It isn't pi.. too many reoccurring 7's :P

[EclecticSceptic]

@C2aimar123 Cool, whatever number that is.

[v4extreme]

cool. actually helps me understand this crap some.

[cha0sd00m]

[bL1zZ4rDzZuU]

nice!

[Learn2Burn22]

yea, i've heard that some mathmeticians are payed to figure out the digits of pi(e). Lucky basterds

[Lausnersner]

good vid but thats now how archemedis calculated it i think 4/5
