Follow-ups to two past blog entries.

First, remember on our most recent trip to Las Vegas (last March) we repeatedly encountered a slow-moving, hand-painted truck labeled “Henry’s Moving” on the drive out. Well, after a trip to Fry’s this past Sunday, we spotted it again.

Second, for the first time in 1½ years, I managed to spot Venus in broad daylight again. I went downstairs to grab a snack about 3:20 this afternoon, and noticed the first-quarter moon in the East. Remembering how I located Venus the first time, and already in the shadow of the building, I traced a line from the moon toward the sun, and found it, a tiny white point in the light blue sky. It was almost directly overhead, and just outside the area around the sun where the sky turns increasingly white. I lost sight of it, but managed to locate it again before I went into the cafe, and once more when I walked out.

I probably looked silly, staring straight up at the sky. But hey, how often do you see another planet during the day?

Edit: I went back down a few minutes later and took a photo. It actually showed up, which seriously surprised me.

Daylight Venus

With any luck I’ll finally post about last week’s trip to Las Vegas soon, but meanwhile, here’s something interesting that we spotted a couple of times on the drive back: The shadow of a contrail against the sky.

Here’s what it looked like, as the camera saw it. Actually, it was much more visible at the start. It faded considerably in the time it took to get the camera out and snap the photo.

Contrail and shadow, unprocessed

And here it is with the contrast enhanced. You can see a dark line extending across the sky from the end of the trail down to the lower left. The sun was at the upper right, almost but not quite in line with the trail at that point.

Atmospheric Optics has a huge collection of cloud shadows, rays, rainbows, ice halos, and more, including a diagram of how contrail shadows work.

Irish and Mexican FlagsI caught a story on The World (PRI) today about Los Angeles band Ollin’s song tribute to Saint Patrick’s Battalion (in Spanish, El Batallón de Los San Patricios)—a group of several hundred primarily Irish Americans who, during the Mexican-American War (1846–1848), left the US Army to fight alongside the Mexicans. They fought fiercely for a year, but came to a bad end: most were captured by the US and executed as traitors.

Cover of Solo #11It reminded me of a story Sergio Aragonés told last year in his issue of Solo (#11). In “Heroes,” he talks about growing up in Mexico, where the San Patricios are national heroes. They have statues, memorials, and a commemorative ceremony every year on the spot where they were executed. After telling the story of how he learned about the battalion, he jumps forward a few decades. Living in the US, with his daughter going to American schools, he wanted to see how she would learn about the heroes of his youth. So he looked through her textbook to the section on the Mexican-American war, and found only a fleeting remark about how a bunch of drunk Irishmen deserted the US Army, surrendered, and were executed.

It was a surprisingly serious story from an artist known for his comedy (some of the other stories in the issue are drop-dead funny), and an interesting commentary on how nationalism shapes our views of history, with one side elevating the battallion, and the other trivializing them.

An NPR story about an archaeological site in Peru mentioned that the ancient Andean calendars used a 10-day week, and I started wondering what other measurements various societies have used. The seven-day week is (almost?) universal these days, developed independently in both the Middle East (spreading to the West) and in the Far East, but past societies have used anywhere from three days to ten.

Unlike the day, year, or lunar month, there’s no natural unit of time corresponding to the week. So it’s hardly surprising that different societies have chosen different lengths. Ten is one obvious choice (there’s a reason we refer to number places as digits, after all). But aside from the obvious Biblical origins, why seven?

Well, seven days roughly corresponds to a phase of the moon. But humans have long had a fascination with the number seven, no doubt influenced by the seven heavenly bodies: the sun, the moon, and the five visible planets. Sunday, Monday (moon day) and Saturday (Saturn day) are obvious in English, but Tuesday through Friday are a little less clear: you have to work out which Norse god the name comes from—Tyr, Wotan, Thor, Frigg—and convert to the corresponding Roman god—Mars, Mercury, Jupiter, Venus. It’s much clearer in Romance languages, as I discovered when I studied Spanish a few years ago. Wikipedia also has a nice table of weekday names in various languages.

On a related note, if February were a full month, today would be February 30. It turns out there’ve been a few of those in relatively modern times, including an extra-long leap year in Sweden in 1712, and two in 1930-1931, when the Soviet Union tried to use a “revolutionary calendar.” (Funny how those never seem to catch on.)

They say that the Southern California car culture is isolating. It’s hard to argue with that, when everyone’s shut up in their own little boxes. But today, on my way to work (delayed a bit on account of dentist), I was listening to KCRW’s Morning Becomes Eclectic and stopped at a traffic signal. They were playing a live version of Elvis Costello’s “Allison.” I looked in my rear view mirror, and realized that the driver behind me was singing along to the same song. Even though it only went one way—she had no way of knowing I was listening to the same music—it was still a moment of connection through shared experience.

For various reasons, braved the crowds at South Coast Plaza yesterday. Oddly, it’s the easiest mall I’ve parked at all weekend. Getting to the Marketplace was a disaster, but that’s just because the streets are wholly inadequate to get cars in and out of the parking lot, and the Village (formerly the Mall of Orange) was just plain full.

At South Coast, as part of their Christmas decorations, they had these giant, shiny, 14-pointed stars hanging from the ceiling in several places.

Stars of Doom!

Classic Christmas, but when you go down to the first floor and look up, there are all these giant, gleaming spikes hanging over your head.

Death (star) from above!

It’s a little disconcerting. “Death from above!” is not something I want my holiday decorations to invoke.
