I just realised that today is pi-day AND today is my cake-day life just couldn't get better. Because I want to celebrate that I give you some delicious pie ;)

ELI5: If pi is irational and has infinite decimals does that mean we can never calculate an exact circumference of any given circle

As an irrational number, what makes pi different from all the other irrational numbers?

TIL that, although 22/7 is the best-known rational approximation of pi, there are better ones, for example, 333/106, and 355/113. The latter differs from actual pi by only about 0.0000003.

Eli5 How is pi derived? I'm sure actually measuring the dimensions of a circle would not be adequately accurate.

How are we able to accurately measure irrational numbers such as pi to millions of digits?
-
Apéry's constant ζ(3) is an irrational multiple of π^3
-
ELI5: With world record calculations of pi, how can we be sure that the digits calculated are accurate to the extent claimed?

TIL A river's meandering is described by its sinuosity – the length along its winding path divided by the distance from source to ocean as the crow flies. It turns out the average river has a sinuosity of about 3.14 or…

Universe with a different value of pi?

Are irrational numbers irrational in other number base systems as well? Is it possible to have a base system in which pi is a rational integer?

How is pi calculated? I know it's not from using circumference/diameter because you would need perfect measurements.
-
How do computers accurately perform calculations which involve irrational numbers such as Pi and e, if these numbers have infinite digits?
-
Why is the circumference of a circle defined at 2Πr instead of Π(diameter)?
-
Happy Pi-Day (:

Why π/e is irrational
-
If π truly has infinite digits there's another π inside π
-
ELI5: How are very accurate values of Pi calculated?
-
The Tau Manifesto
-
If pi (or any irrational number) includes every number sequence, it must eventually include a number sequence that encodes a perfect simulation of our universe.
-
ELI5: Why is pi (π) considered to be irrational even if it can be represented as circumference divided by diameter (c/d)
-
ELI5 why the value of pi is very important?
-
Is there any pattern in digits after decimal point for irrational numbers (like Pi)? If not, are these decimal truly random?
-
Pi = 4 ?
