Pi Striptease

When the irrational and transcendental number π occasionally reveals herself to excite the mathematical brethren of her numerical or geometric hidden properties, be it through some new beautiful pattern or little juicy theorem.

Both number theorists and numerologists get pretty aroused when they get invited to attend a pi striptease event (by invitation only), whose aha! moments could get them mathematically excited for days.

Pi-bond

A dance move which involves pointing your elbows out and rotating your hands around by your chest as if imitating the movement of the bond between 2 p-orbitals as seen in chemistry.

Everyone thought he had lost the dance-off until he pulled out the Pi-bond move.

Pi Chart

A bar chart whose adjacent vertical bars have heights proportionately based on the digits of the decimal number π—from a distance, the statistical diagram looks like a city skyline.

On a graph paper, what is the most number of bars you can draw for a pi chart?

On Cloud Pi

The latest e-commerce shiny object, where math educators’ memories of Pi Day events are stored in the cloud and can be downloaded for a fee—charges are based on a customer satisfaction index (CSI), which ranks each memory or story in proportion to the degree of pleasure or satisfaction it brings.

With schools unlikely to open for another year, which by then the pandemic is predicted to have subsided, being on cloud pi is the closest experience for math students and teachers to vicariously be on cloud nine on the most important date in the mathematics calendar.

Dog Pies

Dog Pies are dog feces piles of poop, usually in the lawn of someone who owns a dog.

"Ew dude, did your dog have Dog Pies on the ground?"
"Yes!"

Pi Second

The fifty-third second of 9:26 a.m. of March 14, 2015. So called because 3.141592653 is pi down to nine decimal places, and Pi Second is 3/14/15 9:26:53.

On Pi Second, we will play the sound of a bell ringing for all the world to hear! Pi Second is only one second out of every 100 years, so it only happens every three billion or so seconds. Enjoy the second while you can!

Pi in the Sky

When the passengers on a plane up in the sky are separately seated based on the the digits of the decimal number π—there are three empty seats between the first and second passenger, one empty seat between the second and third passenger, four empty seats between the third and fourth passenger, and so on.

On a Boeing 777, how many passengers could take part in the “pi in the sky” experience?
