This recounted moment of personal history, which induced the author to reflect on the many times he’s been told that he looks just like someone else, started out as a holiday greeting to colleagues and friends a few years ago. Using analogies to quantum physics and to the distinction between particles and waves, it addresses how we are all connected to each other and mutually entangled, to make it resonate (albeit subtly) with some of the pressing issues of our day: e.g., isolation, identity politics, polarization, silo culture, and whose lives matter.
