I was browsing code golf and I came across this challenge:
https://codegolf.stackexchange.com/questions/68685/the-rien-number
It caught my interest and I wanted to learn a bit more about the Champernowne constant. I did some very brief googling and I can't seem to find what's the significance of this constant.
With that said, why (do we)/(should we) care about this constant?
