‘Twas the night before Christmas …

Wait, Mollie, you can’t stay beside the stove. Santa won’t come down the chimney if you’re waiting there. Go on, now, go to bed.

Smokey, you’re wide awake.

And you, too, Sylvester. I see those eyes open.

That’s better.

No, Mollie, you can’t hide behind the toaster oven, either.

Dusty, get out of the birdbath and go to bed. Get in your house. Santa will see you for sure out there! Chloe? Is that you? Go to bed!

Mollie! You can’t hide behind Leah’s old childhood teddy bear. Oh, that’s what you want for Christmas? Well, maybe Santa will bring one.

Molllie, don’t just hide your eyes pretending to be asleep. Put your head down and go to sleep!

There, that’s better. I think.

Zeke, close the eyes, go to sleep, OK?

You, too, Sam. Those eyes, Sam, close those eyes! Santa will definitely see those eyes!

Good dogs.

Chloe, go to bed. The bed heaters are plugged in, so you’ll be warm.

OK, you can sleep inside.

Now I think everyone is in bed and asleep.

And soon, we’ll be visited by that right jolly old elf …

Twinkle, twinkle, city lights

We can see the city lights from our front door.

They twinkle.

The video doesn’t really capture very well what the eye sees. I think the twinkling is more pronounced on cold, clear nights. That’s when there is a lot of variation in the air temperature, which can cause twinkling at the air moves around. Windy nights might be good as well, but we haven’t had a windy night without rain and fog, so the lights haven’t been visible then.

I have read that stars twinkle but that planets do not, unless they are visible near the horizon. The reason is that stars are point-sources, while planets are not. The light from a star appears to twinkle because of atmospheric refraction of the light. The refraction would be constant and the light would be steady if the air were still, but the atmosphere is constantly in motion, so the light from the stars has to travel through a medium whose density constantly varies along its path. Planets are actually discs. You can see that with a telescope, but even without a telescope the width tends to suppress the effect of refraction.

This site explains the twinkling by saying that a star’s light follows a zig-zag path, but that’s not exactly accurate. If you stand next to someone and look up at the night sky, you can both see the same star, but the light that falls on your eyes follows a slightly different path from the light that falls on your friend’s eyes. When the light going to your eyes is refracted away from its path, you end up not seeing that light. However, light that was following a different path is refracted into your eyes, so it looks like it comes from a slightly different location. That makes the star seem to move very slightly in the sky, which we see as twinkling.

When I look out at the city lights, the smaller lights twinkle while the bigger, brighter lights don’t. In this case, the small lights are like stars, and the bigger lights are like planets. None of them are point sources, so you might think they wouldn’t twinkle, but their light is passing through the densest and (often) most turbulent part of the atmosphere, which is enough to make them twinkle.

The old, blue Dodge

Back in 1995 I ordered a brand-new 1996 Dodge Ram 2500 with a Cummins turbodiesel engine. I had gone though a 1984 Datsun pickup and a 1987 Ford and had decided that I wanted a real truck. It was the first year of Dodge’s “big-rig” look truck style, the one that Dodge and now Ram has used ever since. I sat down with the salesman at the dealership and went though everything I wanted. He nodded and said yes until I said I wanted a manual transmission. That stopped him. Not many people wanted a manual. But I wanted every little big of mileage I could get, and the manual did a better job than the automatic in those days.

Almost immediately after I took delivery, I drove the truck down to Mexico with my friend Tom, who is fluent in Spanish. We went beyond the frontier, deep into the parts of Mexico that most tourists don’t go. We stayed in motels that had gated courtyards, like an old castle keep. We went to department stores with no English speakers anywhere except us. We ate food cooked on wood-fired grills. Tom took a picture of me and the truck somewhere in Mexico.

Both of us were younger in those days.

Most people who buy pickup trucks use them as everyday transportation, just a very big, inefficient car. It was my only vehicle for a while, but it got reasonable mileage for something that big, around 20 mpg. But I also used it as a truck. It was in pretty constant use as a truck while I built my first house, where Leah and I lived before we moved to our current house. That diesel engine was loud. When I visited my friends Errol and Cookie near Atlanta, they said they could hear me coming from a couple of blocks away (that might have been an exaggeration). Errol said it sounded like the garbage truck coming. Here is a photo I took of the truck, my father, and one of my Dobermans.

Those are the footing forms I built for the house. The forms themselves were a major construction project. I had to step them down around 20 feet from the highest corner of the garage to the lowest back corner.

When I bought the truck I was living in Alabama, where I worked. When I moved back to Rome in around 1999, I decided I needed something a little smaller and more fuel efficient, so I got a VW diesel. That got 50 mpg. I kept the truck because the house construction went on for a long time. I eventually got another truck in 2003, and rather than trade the old blue Dodge, I sold it to my brother, Henry.

Henry drove the truck from 2003 until he died last April. He used it down in southern Mississippi when he worked for Presbyterian Disaster Assistance, helping people rebuild their homes after Katrina, when just about everybody else had forgotten about the hurricane victims. The truck got worn and dented, inside and out. It needed various bits and pieces, some of which were no longer available new. Through everything, it just kept trucking’.

When Henry died, his older son Thomas took the truck. Thomas lived in Atlanta at the time, but moved to Dallas a few months ago. We hadn’t heard from him since he moved, so we were glad to get a text Saturday. Unfortunately, it was not good news. Someone had stolen the Dodge, and it had not been found.

It’s so old it has very little value, except for the Cummins turbodiesel engine. That apparently has a fairly high value. But maybe it wasn’t stolen for that reason. Maybe it was just someone off on a joy ride. Maybe it will show up. Maybe it won’t be dismantled, wrecked or burned. I hope so.

If a leaf falls in the forest

When I take the dogs for their long morning walk, I usually drift off into thought. I can walk hundreds of yards without remembering anything about the actual walk. On one of our walks recently I suddenly realized there was a fairly loud noise coming from the woods. I stopped and looked, and then I realized it was the sound of leaves falling off the trees. I couldn’t believe at first that it was just leaves. I tried to get a video so you can hear the sound, but it may be hard to hear. I saved the video in two formats. Maybe one will be better than the other. I can’t really see the leaves in either of these.

If you can’t hear the leaves falling, here is a shut of some leaves and moss that I though was nice.
