So, people just realized the relation between the radius/diameter and the circumference of a circle?
It might just be me, but I was kinda taught that when we first learned about Pi.
holy **** ... the very first time i tried shrooms i tripped on this on the wikipedia page for probly 2 hours trying to figure out how and why that wheel went 3.14 EVERY time. now every time i see that i remember that fateful day
Put simply, pie is just the ratio of a circles diameter to its circumference.
If you don't remember the terms, diameter is distance across, circumference is distance around.
