Why do I go by the name 'Luke314pi' online? When I was in 5th grade, my math teacher said if anyone in the class could memorize the first 100 digits of pi, he would give that student $20. I won the bet. Around the same time I got AOL for the first time, and I needed a unique screen name. You can imagine how many Lukes were already out there, so I needed something different. And thus Luke314pi was born. I still remember every one of those 100 digits today. They don't go away.
