The Pi Pie Chart

Today my students were learning about Pi, its origins and its irrationality. We used this handy website to look up things like the date, and our birthdays to see where, in the first 200 million digits of pi, they resided. It helped us visualise what it means to have infinite digits (as much as one can).

Someone came up with the idea of looking at the distribution of each digit 0-9 within the first 200 million digits to see if there were any interesting patterns. Disappointingly, the only pattern is that they are roughly evenly distributed. But that didn’t stop us making a Pi Pie Chart… even though I hate pie charts, I made an exception because punny.
