My Favorite Pieces of Pi
March 12, 2015
Over the past couple of years I’ve dedicated a number of posts to the way I’ve been looking at Pi. In recognition of the upcoming Pi Day, I’m reposting some of my favorite images from these past posts.
Though not very beautiful the following image, which I did in as an Excel document, is one of my favorites, as it visually illustrates different common estimations of Pi, and how they compare to each other.
From these images, it looks to me that there’s a difference, though not much, between 3.14 and 3.141592 though the difference between 3.1416 and beyond is indistinguishable to mere mortals.
I wrote a post about a cut-and-paste pi project. It’s illustrated with 19 photos. The link to this post embedded in the caption below the photo.
What I like most about this project is that it lets you hold a piece of .14 in your hand.
I also made some coloring pages, for pi, which I collected in a Pi Coloring Book-style pages pdf.
This fractional representation of Pi is the most accurate estimation of pi with a denominator under 10,000. Here’s the way I colored it in:
Here are a couple more of my Pi coloring pages:
Then, I decided to try my hand at creating a one-page explanation of Pi :
This past summer my cousin was visiting. He needed to figure out the size of the rim on a wheel of his bicycle, and was having trouble with the measurement because it was circular. You know where this story is going, right? I suggested that he measure the diameter then multiply by 3.14. He seemed politely interested, but I’m not sure if think he actually considered trying it. After all, it sounds like hocus-pocus.
Happy Pi Day!
