Incident On A Country Road

Yesterday, April 29th, I witnessed people being great. Returning along Highway 50 from Jefferson City Missouri, I was passing through Osage County when I spotted a dumped motorcycle to my left. The bike—a newish gold something-or-other—lay on its side, trailing a scatter of broken parts back to a man who was on knees and elbows, clearly hurt. A FedEx truck was ahead of my. I pulled over just behind it. A house was directly across the two-lane from us. People were in the yard. The FedEx driver sprinted to the house to tell the folks about the accident. I ran toward the man. By the time I reached him two more cars had stopped and a group of people converged on him. He had gotten to the grass and rolled over. A bloody mess, at first glance he looked in very bad shape. He was still wearing his helmet, moaning and trying, ineffectively, to take it off. He kept saying “I can’t breathe…” An older man had his cell phone out, dialing 911. A woman, who seemed to have some training, possibly a nurse, helped him unstrap the helmet and pull it gently off, whereupon he lay on his back, legs pulled up, arms sort of help up, covered in blood. The “nurse” cautioned him not to move. Someone else had brought a plastic sheet, which she directed a couple people to hold above him to shield his head from the sun. I started asking questions—”Can you feel everything?” “Oh, yeah,” he said, “everything hurts.” “No tingling?” No. “Open your eyes and look at me.” His pupils looked normal, but that’s not always a reliable telltale. “Oh, I didn’t hit my head,” he said. “Everything else, but not my head.” I looked at his helmet. “Your helmet says otherwise,” I told him. Half of it was badly dented and scraped all along the faceplate. “What happened?” someone else asked. “I think a blow-out,” he said. “I tried to hang onto it and slow it down…” I went over to the bike. By now about eight people were there, two semis parked along the highway. One man was doing a good job of directing traffic through the momentarily constricted access. More cell phones were out. The debris appeared to be all peripherals—mirrors, plastic molding, packs of cigarettes, a cassette tape, mangled sunglasses. The rear tire was missing a long chunk of tread where it had blown. He was lucky in that it was the rear tire. If the front had blown he would have lost it immediately, at sixty-plus miles per hour, but there were no skid marks. He’d managed to slow it down a lot before it dumped and he’d dumped it on the shoulder. When I returned to tell him this, ambulances were on the way. He was laying on a rock and wanted to move off of it, but everyone kept him in place, not knowing what else might be broken. He was coherent. He was a good rider, evidently, and had controlled the spill marvelously from what I could see. The ambulance arrived, along with a truck from the local fire department. The crow began to disperse. As one of the trucks started rolling, the driver tossed the man directing traffic one of those bright orange and yellow safety vests. With nothing more to do (and having done almost nothing anyway) I took my leave. Traffic was slowed and obeying what I now saw were two men, one on each side of the slight hill where all this was occurring, directing. Those who had done whatever they could have and no longer needed to be there were starting their vehicles and moving out in an orderly manner. All those people had seemed to appear out of nowhere, and very fast, and just did this thing. They helped, if only by being willing to stop. It felt very good to be a human just then.

Arch photos

I love photographing the most famous monument in St. Louis, Missouri, the Gateway Arch. I've spent time at the riverfront downtown St. Louis for the past two nights. Last night, it was for a business meeting, where I shot this panorama (click the photos for a expanded views): arch-panorama-2 Tonight, my wife and daughters returned to watch the sun set--the river water was high, making the river look much larger than usual. I focused on the sky, though, including this vertical panorama: stretched-archIt was taken by standing directly under the arch and shooting up. For a thicker version of the arch, move up to within 30 feet of one of the legs and you'll end up with this: thick-legAs the sun went down, I shot this silhouette of the south leg and some of the visitors. south-legShortly thereafter, while walking back to our car, my 11-year old daughter JuJu was struck by the color of the river bank lit by the streetlight. That image is the somewhat eerie ending to this little gallery: streetlightNone of this is difficult to do; it's all there for the taking. BTW, I used a consumer grade camera (the Canon Powershot SD1100IS). For those interested in the geometry of the arch, Wikipedia offers this:

This hyperbolic cosine function describes the shape of a catenary. A chain that supports only its own weight forms a catenary; in this configuration, the chain is strictly in tension. An inverted catenary arch that supports only its own weight is strictly in compression, with no shear. The gateway arch itself is not a catenary, but a more general curve called a flattened catenary of the form y=Acosh(Bx); a catenary is the special case when AB=1. While a catenary is the ideal shape for an arch of constant thickness, the gateway arch does not have constant thickness as it is narrower near the top.

Another Musing on Our Evolving Ability to Perceive

I have occasionally ruminated our improved ability to see and understand the universe around us. On this blog, it usually is in terms of comparing the Young Earth view with what we've learned in the last few hundred years. Posts such as The Universe is not Specified to Human Scale and My limited vision make the point. But I've started another blog that focuses less on politics and culture, yet found that one of my first posts again addresses the issue of how we've improved our vision of the world around us in the last few dozen generations. Please peruse The Object At Hand: Light Lens a Hand, to Help us Understand and see if I am off the beam.

The fake problems of infomercials

I caught this video on the Daily Dish. It is a compilation of excerpts from numerous infomercials. This excellent editing of a string of disasters that suggests the need for one more infomercial offering this bit of free advice: Slow down; quit being such materialists; simplify your life and quit acting so recklessly. Excellent humor and anthropology, "kickintheheadcomic"! I suspect we'll soon be hearing a new soundtrack on this clever video, unless the creator has his use rights to the Beatle's "Help" nailed down . . .
