To achieve certain narrative effects, I've fiddled slightly with the floor plan and the interior design of St. Mary's Hospital in San Francisco. In this story, the characters who work at St. Mary's are fictional and are not modeled after anyone on the staff of that excellent institution, either past or present.
I'm not the first to observe that much of what quantum mechanics reveals about the nature of reality is uncannily compatible with faith, specifically with the concept of a created universe. Several fine physicists have written about this before me. As far as I am aware, however, the notion that human relationships reflect quantum mechanics is fresh with this book: Every human life is intricately connected to every other on a level as profound as the subatomic level in the physical world; underlying every apparent chaos is strange order; and "spooky effects at a distance," as the quantum-savvy put it, are as easily observed in human society as in atomic, molecular, and other physical systems. In this story, Tom Vanadium must simplify and condense complex aspects of quantum mechanics into a few sentences in a single chapter, because although he isn't aware that he's a fictional character, he is obliged to be entertaining. I hope that any physicists reading this will have mercy on him.
