There is a chain of upscale pizza restaurants based here called π. Clever. The family had lunch at the downtown branch after the women's march. I was more interested in a glass of iced tea, though, than the expression of a non-repeating, infinitely long ratio.
Once in a (very) great while I wonder how pi was discovered and calculated. The hunt has been going on for at least 4,000 years. Check here if you give a hoot.
