Pi Calling

When the number π is hinting to math educators worldwide to turn the wealth of wisdom about her, which has been unearthed over the centuries by thousands of men and women of mathematics, to launch or produce “new” math products that would help them generate a new or rich source of income.

Mathepreneur Ian has identified a few game-changing ideas that have laid hidden in quiet cul-de-sacs in both academia and in publishing houses—he’s doing nothing new but answering to pi calling.

Mathematical Do-ness

Forcing or motivating yourself to DO-ing some math to beat your daily laziness, especially if you are glued or addicted to your cell phone or digital device for an unhealthy number of hours every day.

Some mathematical do-ness activities that could help white-collar workers break away from their sedentary lifestyle are:

Walk exactly 6789 steps.

Create an origami geometric shape out of the newspaper.

Learn to do calculus—differentiate and integrate—with a soroban (Japanese abacus).

Count the number of ballpoint pens in your house.

Pimester

A period of about π months, as a division of the duration of a woman’s pregnancy, which is less than a hundred days.

Janette’s craving for pineapples and prawn mee went unabated during her pimester.

The Uberization of Singapore Math

When students, teachers, and homeschoolers could access affordable or quasi-free quality grades K–12 math resources based on the math curriculum from the “fine” city of Singapore, by bypassing traditional channels of distribution or mercenary middlepersons.

Thanks to print on demand (POD), the Uberization of Singapore math has significantly leveled the playing field for self-published authors and small publishers, as they needn’t rent a warehouse to store their books and rely on cut-throat distributors and bookstores to sell their titles.

PAPralysis

When Singaporeans and permanent residents often feel powerless or helpless how to improve their standard of living in the midst of a rising cost of living, and with most local and foreign companies unspokenly preferring to recruit foreign rather than local talents, because they are a cheaper and submissive source of labor—locals and PRs feel that the half-century-old ruling party is quasi-clueless how to help them.

Is PAPralysis a bona fide word for Scrabble?

Mathematical Fraud

One who has achieved far beyond what his average or below-average mathematical intelligence could allow him to do, by lying, bullshitting, scheming, pretending, or backstabbing—the mathematical equivalent of a racist-rapist-turned-fraud-felon who got elected, rejected, and reelected despite all the odds against him.

Guesstimate how many mathematical frauds make it bigly in the publishing industry worldwide every year.

The Moronification of Singapore Math

The process of making the Singapore math curriculum, or part of it, accessible to all dummies and idiots, especially among those who have an irrational fear of the bar model method, which is the soul and heart of Singapore’s elementary school mathematics.

Mathepreneurs leverage on the moronification of Singapore math to help raise the quantitative literacy of millions of math-anxious or mathophobic students and their parents worldwide, who have since become better and more confident problem solvers.
