Pi

A number that is 3.1415926535897932384626...
You can memorize the first 50 digits and then say you know hundreds because people get bored of listening to you say numbers.

You: I know 200 digits of pi
Friend: Show me
You: 3.141592653589793238-
Friend: Wow
You: That wasn't all of them
Friend: I don't care

PI

PI is short for the Philippine Islands. Philippine Islands is the old name of the Republic of the Philippines. The Philippines was formerly known as Las Islas Filipinas, named after King Felipe II of Spain, when it was a colony of Spain from 1565 to 1898. Then it was Anglicized and it became known as the Philippine Islands when it became a U.S. territory shortly after the Spanish-American War of 1898. In 1946, upon independence from the U.S., it became a republic. The name of the country was then changed to the Republic of the Philippines.

Yo, I’m going back to the PI next year.

Predictive Pi

When both mathematicians and AI could forecast new mathematical results on the number π based on published papers and from recently awarded pi-related research grants.

Predictive pi has somewhat democrarized previously secretive research conducted by both pure and applied mathematicians around the globe.

The Pi in Me

When there is a hidden element of π residing in all humans (or maybe even animals), whether they know it or not, regardless of their experience of school math—that pi-mind consciousness that intuitively seems to be guided by some Higher Being to convey new insights about the “sacred number” to humanity or any living entity.

When someone puts themselves in a Zen-like or transcendental state, the chances of them experiencing “The pi in me” aha! are higher than when they’re constantly being bombarded with a deluge of sensory input.

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.
