A Week of Cool Math for
Global Math Week 2019

Day 4

Mile of Pi

Brady Haran selected two videos to share in honor of Global Math Week.  The first one was the selection for Day 1; the second one is Mile of Pi.  Brady said, “These videos seemed like impossible dreams.  How could we print out 1 million digits of Pi on a continuous piece of paper?  Turns out there was a place in Denmark that could help.  Where could we possibly roll out a mile-long piece of paper?  Turns out there was a runway we could hire.  Where could we get hundreds and hundreds of pies to make into a big Pi demonstration?  Turns out a friend of mine worked in a pie factory!  I love these videos because they were silly ideas that somehow came true — and they resulted in memorable demonstrations of why we’re all so captivated by Pi.”
