Happy π day!*

This post's theme word is diktat, "an order or decree imposed without popular consent or upon a defeated party." The Gregorian calendar's vagaries of calculation and representation compel the diktat: pi day occurs on a bleak, cold day in March, when pie fruit is least available in the northern hemisphere.
*It is π day for places that write the date US-style: month/day/year. For European-style dates (day/month/year), π day either doesn't exist or will take place the 3rd of February, next year (which, after all, will be the 14th month of 2015, in a manner of reckoning). I also like Vi Hart's "Engineer's Pi Day" on 3/14/16... see you next year!
