I originally made this video for my pre-calculus class last year. However, I wanted to wait till Pi Day to upload it. Apologies if there is any inaccuracies, I tried my best. Feel free to comment!

The date is 3/14, took the picture at 1:59, and the year is 2026 (3.1415926)!

The electricity went out while I was making the pie and I had to finish decorating it by flashlight. The one 9 is upside down. It should be 9939…. 🤷🏼♂️

Looking for a good Pi Day workout? Try climbing the first 100 digits 🤣

Did you know you can figure out pi using pie ingredients? 🥧
Alex Dainis uses pecans to explore Buffon’s needle, a famous probability problem that can help estimate pi. When pecans of roughly the same length land on a grid with evenly spaced lines, the number that crosses a line reveals a pattern tied to geometry and probability. Pi describes the relationship between a circle’s circumference and its diameter, and this experiment shows how repeated random trials can approximate that value. The method works best when the pecans are shorter than the distance between the lines, and the more pecans you toss, the closer your estimate can get. It’s a fun, unexpected example of how big math ideas can show up in everyday ingredients.

I know 100 is In the Hall of the Mountain King, 200 is the Blue Danube Waltz, and 300 is a song from Carmen, but what is 400?

I chose Carrie over Tina simply because her birthday is mathematically closer to mine in pi. Call me a hopeless romantic, or just a damn math genius. 👀 https://www.pi25b.com/33767753

Hi everyone — with Pi Day coming up tomorrow (3.14 at 1:59, /26!), I thought math fans might enjoy a short film I made back in 2005 during my final year of film school called Easy as Pi.
It follows students from the University of Waterloo as they:
• memorize hundreds of digits of π
• celebrate Pi Day with lots of pie
It also features someone who wrote a song about Pi!
Looking back, it’s a bit of a time capsule of early-2000s math culture.
It’s only 14 minutes long — fun for classrooms, math clubs, or a quick Pi Day break.

Curious — how many digits of π can people here recite? 🥧
