When I was about 5 years old, I had my tonsils taken out. My Grandma Kopson bought me a gift, to cheer me: a handheld calculator. It seemed as large as a brick — much larger than today’s calculators — and used a lot of batteries. And I loved it. I loved to play with numbers, try little experiments with numbers, see numbers. That love of numbers and math has extended to the present. I am using calculations with my research in “Physics of Community”, which studies community decision making, power, conflict, competition, cooperation, and the like. What do you love so much that you doodle with it in your spare time? Dance? Writing? Piano? Gardening? Woodwork? Cars? These are things that we excel at. Let us never give up our pursuit of Excellence in those things we love.
