The year was 1998, grade 8. The maths teacher was sick and a substitute was allocated.
He reads the notes. Learning about pi. Asks the class, "Does anyone know it's value?"
Of course I knew it was 3.14159.
Week passes. Teacher is still sick. New substitute is allocated. Reads notes. Learning about pi. Asks the class, "Does anyone know it's value?"
Since very little was done in that last week, I committed 3.141592654 (accuracy of calculator).
3rd week, same deal with new substitute. Get to 20 decimal places and figure it is a challenge at this point.
4th/5th week work up to 50 decimal places.
Over weeks 5-8, work my way up to 101 (just the way it falls).
Year 11/12 comes around and I have teachers sending out students to find me, bring me back to their class and recite pi for a minute.
I know 100 decimal places is a drop in the ocean compared to others, but I had mastered pi.
