Pi’s Block

The math constant’s equivalent of writer’s block. When the number π frustratingly finds herself facing a blank page with zero output on her part, often spewing out a string of four-letter words.

Unlike her constant counterparts like e and 𝜙, rain or shine, π doesn’t give the excuse of pi’s block to rationalize why she’s semi-productive or unproductive on certain days.

Naked Pi

Exposing the mysteries, magic, and myths about the number π to an oft-innumerate or semi-mathophobic lay public, who secretly desire to gain an understanding or appreciation of the beauty, ubiquity, and utility of mathematics’ most famous constant.

Prof. Ian recently revised and updated “Naked Pi,” which is presently available for sale only on the dark web, because part of the book’s mature or woke content might not go well with a conservative or puritan audience.

Pi Prank

Some silly, reckless, or deadly act underperforming or poorly motivated students perform on their oft-mean teacher on Pi Day, be it for fun, malice, or revenge—when these rowdies or troublemakers want to get even with adults on this most popular date in the math calendar.

Playing pi pranks like throwing a whole pizza at a teacher’s face and ordering a cicadas pizza for the math HOD is often a paying-back time for rogue students to humiliate the teaching staff.

Is Pi Democrat or Republican?

When politicians and philosophers fail to agree whether the irrational number π subscribes to the liberal or woke ideology of the Democratic Party, or shares the conservative or puritan beliefs of the Republican Party (and maybe even the MAGA gospel of the Trumpublican cult).

Metamathematicians don’t think that π will ever conform to the biblical value of three, which is preached by some alt-right Christian nationalists, while far-left ethnomathematicians divine that π holds the secret to the workings of the universe. Is pi Democrat or Republican?
