Pi Pa

A creepy ass grandpa, the type of grandpa that doesn't care about incest and talks like a smoker. Gets mad about everything and is horny all the fucking time.
"MOM!! Pi Pa is having the cat lick milk off his dick again!!!"

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.

beta theta pi

The best frat ever. Which isn't saying much. All the guys are mid, yet the atmosphere is top tier. If you go to a beta party, you will feel like a ten simply because these men are desperate. Stay away from Topher.
1: Did you hear beta theta pi is throwing tonight?
2: Oh shit! Don't drink that wine again!

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.
