M2C2A: Episode 6, Pi: A three part mathematical journey through the mathematical constant we all know and love, Part 1

We've all heard about π in any random moment in our lives, but getting down to brass tacks: "What is π?" is a more complicated question.
To answer it, I'll answer the following:
1. What's so special about the circle ?
2. Can we imitate a circle that it's circumference is not π?
3. Can we find sequences in the digits of π?
1. Answer:
A circle is special because it has not infinity sides, but it has none.
In such way, there are infinite curves inside every curve in a circle, making the circle a kind of fractal, where there's a curve inside the curve inside the curve inside the...
To calculate the circumference, π must be used in a way that helps us do it.
But why π?
π is used in circles and spheres for a reason, and it's because it was MADE in such way to do it.
And circles and spheres, including ovals, are ones of the only geometrical shapes that use pi to calculate their area/circumference/volume.
But to what point are we getting with this?
Circles are special because they depend on π.
How to enter a circle (〇) on the keyboard.

First go to Google translate (sorry it's in Spanish), and choose Chinese.
Check the box that says "phonetic writing" and write "ling".
Click the down arrow two times and the right arrow two times more, and press space.
Copy and paste, and you have a circle (definition in Chinese: Unofficial way of saying 0.).
