As a math teacher wrestling with existential questions , I desperately needed that lesson on symmetry. I’ve often heard myself saying that the principles of math are the principles of life, but I hadn’t made the connection to symmetry, or noticed how asymmetrical my life had become until today. I have a beautiful example of mirror symmetry before me as I write this. The apartment building across the way is the mirror image of our own. It occurs to me that the people within have lives that in many ways mirror my own. I have not viewed others this way in the past. I have considered them to be either “better off” or “worse off” than me. I never thought that they might be, in many ways, my own mirror image. Thanks, Umair, for giving me a new way to think about loving others… as well as myself.
