AWESOME !!!
hehe !!
I never thought in this way
Except the letter pi was used to represent the number before they knew that is was approximately 3.14, Also, the greek letter pi pronounced correctly sounds like the letter p in english.
@lvleph The actual pronunciation of π is something I am not aware of.
Thanks for the information.
All this talk about п make me hungry:

Yes, but doesn’t that make it all the more amazing?!? It’s as if the same divine hand (or if you prefer, chain reaction of colliding atoms) that created the English spoken language and Arabic number symbols also guided mathematicians to discover the 4.13 approximation. Mind-blowingly cool.
