A Physicist Contemplates Training Wheels

Motion catches the corner of my eye. Look up. Over there, beyond Spike the cat on his high perch, out the front window, past the rough-barked pine trees. A little girl struggles to get her bicycle going again. It is an impossible bright pink, with incongruous black rims and stout black spokes. Pink helmet, blue-jeans shorts and sneakers, a pink shirt with a pattern I can’t quite make out, probably animals. She pushes and shoves, single-minded, her entire world encompassed by this instant, realigns with the center of her sidewalk highway, and is on her way again, oddly upright. She is gone before I figure out the oddness plucking tunelessly at the back of my mind: her winged Pegasus, pink bike with the black rims and thick spokes, has training wheels.

A minute or two later a couple strolls by, chatting and laughing quietly, comfortable with their daughter on the fluorescent bicycle roaming her sidewalk highway in search of adventures. He is tall—very tall, I realize—dark-haired and relaxed and fills an oversized baggy white shirt and oversized baggy blue gym shorts. She is short, dark-complexioned as well, with long Mesoamerican black hair flowing down a relaxed back over a shapeless baggy garment of muted earthen colors. Her being animates the facial features of a woman from a Central American country, a newborn swaddled to her chest. He laughs again. Whatever world they inhabit in this moment, it seems pleasant—fitting for a quiet mountain neighborhood on this sunny, breezy, unexpectedly warm and easygoing March day. Sharp contrast to the cold hardness and wantonly inflicted greed newly risen from a vat of putrescent bile left simmering in the underbelly of our country.

I can’t help but smile in response to a brief respite in this couple’s welcoming sunny bubble, even at a distance. Vicarious pleasure is still pleasure; escape is sometimes necessary. After perusing the news after telling myself that I would not peruse the news, which seems always horrific in this dank hegemony, seeing the chatting and laughing couple is a surprising if welcome balm, a salve for psychic ills and the hurt billowing across the world.

A study in contrasts, this, but a common theme emerges: disposition emanates and infects, whether one realizes it or not. I think of my leaden, lowering demeanor this morning, then of their easy laughter. I am glad that they can infect me, and not I them, in this chance one-way encounter. We humans are a spongy mirror, the physicist’s black body, absorbing and re-emitting packets of dark or light that happen to intersect our surface—venom or laughter, pain or comfort, bigotry or celebration.

Choices.

But do we create? Can we create? To what extent do we have a choice? If all of us absorb and reflect, then what is the source of the light, what is the source of the dark, these quantized carriers of sadness and joy that scatter through our society, random-walking among neighbors, among couples, among children riding pink steeds along narrow weathered-cement roadways?

It dawns on me that this chatting and laughing couple, this reflection of what is, or can be, right in the realm, is the essence of resistance—resistance to the advancing wave of hard dark bone-seeping cold things, predatory denizens swimming a fouled and murky miasma, this newly-erupted, unwelcoming abyss. This couple and their fleet daughter, emitters of packets of wonder and humanity, whatever their origins, are what saves us. Hold on to this and do not let go, I say to myself, however violent and turbulent the buffetings to come.

I wonder if they are new to the neighborhood. Two world lines intersecting defines a point in space and time, a before and an after, that changes both in the instant, in the mystery, of interaction. Perhaps we will cross walking paths. I think I would like that. Perhaps, even, the training wheels will be off.
