PI in Mathematics

As known the constant  π (PI) would be called as Archimedes constant or Ludolph number. We use this constant to find out the length of the perimeter of the circle or area basically .  And the number π (PI) has infinite  digits after comma.  And that is why this constant is so interesting for mathematicians , it is endless .  We can show the first 1000 digits as below and  it goes on …

The Eternity Between Two Dots

Another interesting side of π (PI) is that it doesn’t include any  iterative bunch of digits  . This means that we have a number with an infinite number after comma that has infinite digits of numbers that comes together by infinite combination.

Now ; if we are clear on that; we can talk about the paradox of the circle;

A circle’s perimeter ,  – which has a diameter  value is  one unit –  ,  is  π (PI).  If we must show the perimeter of the circle as a line on a ruler it will show us a number between 3 and 4 units. But if we look closer  to the digits after the coma of π (PI) we could obtain the constant π by adding every digits infinite times as  ; “π= 3 + 0,1 + 0,04 + 0,001 ….”  endless times for every digit.  So if we are adding  a positive number  to another positive number  for  infinite times  then can we say this number goes to infinite as value. And then could we say the perimeter  of the circle goes to infinite or not ?

This circle paradox has an answer:

Of course π  does not go to infinite , just the digits after 3 goes to infinite . So every rate of rational number that forms π goes to 0(zero) . So π goes to 4 but never reaches to 4 . It is not important how long or how short ,basically ,  a line consists of infinite number of dots.  And you can never show the real π number on a ruler. Because it continuously moves to 4 😉

See you  …
