Aside from recording a moment in time, a photo can also provide a vicarious experience. In the case of this photo of our granddaughter Glenyce Jane, I was first struck by the look on her face and the way she tucked her legs back. I was also reminded of the simple joy I experienced when I was pushed in a swing. (It's been decades.)

Besides the vicarious experience, this photo leads me to think about the science of the swing and whether this contributes to the joy of swinging. You are weightless twice during the arc of a swing. And there aren't many times as a child that you can escape gravity. That sounds like fun, doesn't it? Glenyce's face answers that question.
