Happy Pi Day!

March 14 is Pi Day (3.14...). I remember buying pies for my grade 9 classes to eat when I was a mathematics teacher. It is so cool that the ratio of circumference to diameter is a constant and the number goes on forever - regardless of how large or small the circle. Last fall, I accompanied my school's debate team to McGill Unviersity in Montreal. My first year department head suggested I visit the Cafe Pi on Laurent Avenue. Bought a few souvenirs for my office and had my photo taken by the owner in front of his store.
