Dont forget Tau, which is c/r, and because d=2r, Tau is 2 * pi. Tau turns out to be useful. I have experienced Tau day, when, after traveling home (USA) from China on 3/14, when the plane landed it was still (or, again) 3/14. A coworker pointed out that we could legitimately call it Tau Day. We baked pies as one does- just double the number i suppose. Lol
The previous video in the series: "What is ⅓? It is estimated ⅓ ≈0.33, now technically it goes on forever, it is a rational number. Next I take a piece of string of length a foot, my foot. Then I cut this string into three equal pieces. Lo and behold, when I put the three pieces together, their combined length is the same as my foot. Now you understand ⅓, dumbass. Like and subscribe."
I was taught about Pi in school but this is by far the best demonstration to explain it plainly so that people can have a visual aid to better understand it. Thanks, I'm going to show my son this. ; )
If you complete the circumference with all the string and there is no gap, Then why does it matter how many radiuses you fit around the circumference of a circle? If you enclose the circle then who cares what the ratio of radiuses to circumference is.
Essentially, it's because this ratio allows you to compute the area or perimeter of any circle. If you know radius or diameter, you can know the perimeter of the circle.
There may be a deeper solution to pi that involves "dimension". There may be a simpler explanation. I don't know. One thing that puzzles me is the meaning of pi. Is it really just a number? I dont think so. In language meaning either explains or describes. Pi is a very strange number. I think it's strangeness is due to missing meaning. Another way to look at pi is as an operator. An operator that, when applied to any line, gives a special kind of curve. A number that turns one shape into another. Is there an operator that turns lines into triangles? Squares? Toruses? Hyperbolas? If we could find those operators maybe they'd shed more light on what pi is.
@@kallianpublico7517. The secant if the inverse cosine can turn a point into a line. And the cosine of the inverse secant turns that pine back into a point.
@@jeffthevomitguy1178 How? How do you operate on points? By multiplication, exponents? What is the meaning or solution to any number operating on a point. As an example what is 3 times a circle or square? 3 circles, 3 squares? Cosines and secants have geometric meaning in 2 dimensions. Points are 1 dimensional. Points have no "shape". Even though we think of a line as a shape, what its made of (points) isn't a shape. One point doesn't make a line, but two points joined together do? How? How are they joined? Lines joined by angles give 🔺️, squares ⬛️, and polygons. How are points joined to make lines? By knots 🪢? Can we even have a visual reference? Atoms are joined together by the bonding of the outermost shells of electrons. Protons and neutrons are joined together by the strong nuclear force. Are points joined together by nuclear forces? Chemical geometry: shapes? What are points made of? The truth of the matter is either no one knows, or it can be made of anything. That ambiguity is not resolved by invocation of the trigonometric functions.
...INTERESTING PRESENTATION. But the string remainder should be one-tenthish of the unit lengths. That was not the case in the video. But the strategy was sound. Cheers
Great Salute to The LEGEND and GENIUS of All Time :- ARYABHATA , Who had Given the First Accurate Value of Pie And Many Things in His Life and Can't be Compared to Anyone . Thankyou .
So much of Indian mathematics, especially the Kerala school, is greatly under appreciated in the western world. To venerate Kepler and Newton but not Aryabhata and Madhava is to deny history.

I'd not like to start any political discussion related to history here. But I do infact agree Indian mathematicians are underrated. Aryabhatta did find some decimal places of pi. But Newton on the other hand, used and manipulated the Binomial Theorem to find pi till any decimal places desired. I'm saying Newton's contribution and other mathematicians' contributions too do matter here and are equally on the level Aryabhatta was. मैं यहां इतिहास से संबंधित किसी भी राजनीतिक चर्चा को शुरू नहीं करना चाहूंगा। लेकिन मैं वास्तव में सहमत हूं कि भारतीय गणितज्ञों को कम आंका जाता है। आर्यभट्ट को पाई के कुछ दशमलव स्थान मिले। लेकिन दूसरी ओर, न्यूटन ने किसी भी दशमलव स्थानों तक वांछित होने तक पाई को खोजने के लिए द्विपद प्रमेय का उपयोग और हेरफेर किया। मैं कह रहा हूं कि न्यूटन का योगदान और अन्य गणितज्ञों का योगदान भी यहां मायने रखता है और समान रूप से आर्यभट्ट के स्तर पर हैं।
I'm disappointed with my self , took me 26 years of living ,eating,shitting,sleeping to ask my self this question on 1:33 AM (what is PI why is it 3.14)
Thanks for an interesting question. This video shows that the circumference of a circle comes from the diameter going around the perimeter 3.14 times (or pi). They used an equation of pi = c/d: another way to say this is D x Pi = C or a full circle. Half a circle would only use have the diameter or one radius (2 radius make a diameter) Diameter=D Radius= R Circumference =C Pi= 3.14........ Full Circle. (D x Pi = C) or (R + R x P=Ci) or (2 x R x 3.14) Half a circle (D/2 x Pi) or (R x Pi) To learn more check out this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cC0fZ_lkFpQ.html
