If you're curious about last week's #PiDay article that used a FreeDOS program to "measure" π by counting pixels, here's a follow-up.
It's about how to write an academic journal article in groff— but really, it was an excuse to explain why the method gives π=2.828

Short version: it measures a square inside the circle, so the best you can get is 8cos(π/4) or π=2✓2
*Could be explained better, but the diagrams look really nice!

Missed this the other day, but it was to good not to share…

Pi Day is only one day, but pie can be had every day! My latest food column is up, along with some tasty handheld pies available in town!
Thanks to these fine people for sharing a slice of their time with me :)

It's still #PiDay here in California.
This guy is right, Pi day is just a fake holiday created by math companies to sell more math.
Someone is making BANK on Pi Day!
Hope it's not too late for this #PiDay post...
Q: What do you get if you divide the circumference of a pumpkin by its diameter?
A: Pumpkin Pi.

#PiDay is already over; however, here's an interesting and quite entertaining article explaining why #NASA only uses a tiny fraction [sic*] of Pi's infinite decimal places.
Even for its most accurate calculations, which are for interplanetary navigation, NASA's Jet Propulsion Laboratory uses 3.141592653589793.

* I find it amusing that they really say “a tiny fraction” - because mathematically, a tiny fraction of an infinite number would still be an infinite number. 
NASA JPL EducationHow Many Decimals of Pi Do We Really Need? – News | NASA JPL EducationWhile world record holders may have memorized more than 70,000 digits of pi, a JPL engineer explains why you really only need a tiny fraction of that for most calculations – even at NASA.
