We all know the feeling. There’s something electric in the air. It could be the chemistry between two people who have just met but—oh my—it seems like they like each other. It could be suspense in a movie. It could be peering into an oven at some unfinished dish knowing, somehow, this is going to be good.
There is no evidence for any of it. Nothing you can see or taste or smell. It’s ethereal, the place where history and imagination meet. But by God we know it’s true.
