I’ve written before about how enthusiasm is my favorite quality in others. It’s what pulls me closer to people.
Here, a student describes Richard Feynman’s enthusiasm:
I remember when I was his student how it was when you walked into one of his lectures. He would be standing in front of the hall smiling at us all as we came in, his fingers tapping out a complicated rhythm on the black top of the demonstration bench that crossed the front of the lecture hall. As latecomers took their seats, he picked up the chalk and began spinning it rapidly through his fingers in a manner of a professional gambler playing with a poker chip, still smiling happily as if at some secret joke. And then - still smiling - he talked to us about physics, his diagrams and equations helping us to share his understanding. It was no secret joke that brought that smile and the sparkle in his eye, it was physics. The joy of physics! The joy was contagious. We are fortunate who caught that infection.” -from the foreward of Surely You’re Joking, Mr. Feynman!
