Wasnât that hard
41.3
Mmmmmmm ip.
Yes, weâve proven that pi is an irrational number and therefore has infinitely many digits.
if you picked one digit as the âlastâ one to start with, then you could express it as an integer faction and it wouldnât be irrational. So that canât happen.
You can express pi in irrational bases like base pi or tau, and then you have a finite number of digits (1), but thatâs just putting a trench coat on top of pi and pretending itâs finite length so you can get into the movies. I donât even know what youâd call those digits. But they wouldnât let pi into the airport or courthouse like that.
Being that itâs an irrational number itâs infinite, and to properly recite something backwards youâd have to start with the end which is impossible. But if you start from somewhere in the middle of the number and recite it backwards that would be possible, eg. 41.3. Depends on how much of a stickler you want to be about the rules of where youâre allowed to start I guess for your definition of impossible.
Itâs also impossible to recite pi forwards (entirely).
But i mean to even begin to backwards is far less trivial
True, but ending is a lot simpler than forwards đ
Wouldnât it be equally nontrivial?
Infinite complexity is still infinite complexity. Doesnât matter the direction.
Pi has one end: 3(.14âŚ) (trivial) âStarting at the end of piâ: (non-trivial)
The complexity doesnât decrease either direction but ok! Itâs still infinite.

and so on
âThe train tracks all run parallel but theyâll all meet up one day.â
Zero followed by a one in base đ.
This is true of some rational numbers as well. Take 1/7 for instance.
