A Slice of Pi Day


Today’s the 14th of March, and it’s not just any day. It’s Pi Day! The math geeks among us have been celebrating for years, but this year feels extra special because I finally grasped a concept that made everything click. I’ve always loved numbers—there’s something almost comforting about their consistency in the chaotic world around me.

I spent most of my morning figuring out how to approximate pi using Buffon’s needle experiment. It’s such an odd thing to get excited over, but there’s just something satisfying about deriving a fundamental constant through simple probability and geometry. I laid down a bunch of parallel lines on the floor with painter’s tape—10 centimeters apart—and tossed toothpicks randomly across them.

Each toothpick is 5 cm long, so when one lands intersecting a line, it counts as a hit. As I tossed the toothpicks over and over, meticulously counting each hit, something miraculous started to happen. The ratio of hits to total tosses began approaching pi! By lunchtime, my makeshift lab was starting to look like a scene from an old science fiction movie with all these toothpicks scattered around.

The number slowly revealed itself, dancing between 3 and 4 as more data points came in. It’s such a humbling experience, watching this abstract concept materialize right before your eyes. I can almost hear the pi singing to me—a soft, melodic 3.14159… that goes on forever.

But it wasn’t just about math today; it was about celebration too. I baked a pie—apple, of course—and used the occasion as an excuse to try out my new set of kitchen gadgets. The kitchen smells like cinnamon and fresh apples now, and the pie is almost done baking. It’s not fancy by any means, but there’s something incredibly satisfying about making your own dessert.

As I sit here surrounded by the remnants of this mini-experiment—half-emptied bags of toothpicks, a partially baked apple pie, and a piece of paper with equations scribbled all over—it hits me how much these little moments mean. Simple pleasures like learning something new or baking a delicious treat are what make life worth celebrating.

And so, on this day dedicated to pi, I’m content with the knowledge that I’m not just doing math—I’m embracing the beauty of numbers in my own way. Maybe one day, someone will even remember where they learned about Buffon’s needle and laugh at their old toothpick experiment. For now, it’s enough to be here, enjoying this slice of pie and a slice of pi.
