Pi Machine

An automatic tattoo machine found in some posh shopping malls, which has been engineered for demanding geeks who have little faith in an often-error-prone, math-anxious tattooist in accurately designing the number π.

After inputting the typeface and size of the tattoo into the pi machine, Jack waits anxiously, yet excitedly, for his body art.

The Calendarization of Singapore Math

When Grades 1–6 math questions from the “fine” city of Singapore are creatively or subtly presented on a printed, friendly, colorful calendar rather than through traditional channels like boring textbooks and workbooks, a change of platform often works wonders for math-anxious kids and their parents.

Pitheist

A skeptic convinced that biblical stories are at best 3.14% true (and therefore that God’s nonexistence is at least 96.86% certain).

Anecdotally, pitheists appear to be overrepresented among mathematicians compared with linguists.

Pitriot

Pi-Dollar Shop

A favorite geek hangout that specializes in pi-themed and pseudo-pi merchandise. Most items cost $3.14 each, with a handful priced at $31.41 or $314.15, and a few special collectibles going for $3,141.59 apiece.

Since Pi-Dollar Shop opened, tens of thousands of math-anxious visitors have left with a more positive view of π and math than when they walked in.
