I have a amateur question regarding pi. I know what pi is, in a general sense, but I am looking at equations (e.g, the cosmological constant, heisenberg's uncertainty principle, etc) where pi appears, but I do not see any relation to circles in those equations. I am sure there is, but I just don't see it. Can anyone explain where that comes in and why pi appears there?(adsbygoogle = window.adsbygoogle || []).push({});
