Katie and I seem to do vacations in pairs. We’ll go somewhere on a trip, then a year or two later come back and do all of the things we discovered but couldn’t find time for the first time around. Last April we went to Las Vegas for an extended weekend, did some sightseeing, saw some shows. This year we came back mainly for the shows, and did the trip during the last week of March, driving out on Monday and returning Friday evening.

Standard Rio RoomWe stayed at the Rio, which has very nice, huge rooms—even if we didn’t spend much time there. The casino floor is also surprisingly easy to navigate, unlike some of the mazes on the Strip. We’re probably the only people to stay there four nights and not to see the “Show in the Sky” (some vaguely Mardi Gras-ish production they do with floats that run on tracks in the ceiling).

Of course, it is a bit off the Strip:

But at least it wasn’t as far off as the last hotel we stayed at.

We managed to catch Spamalot (which replaced Avenue Q at the Wynn), Cirque du Soleil’s O (the one with the water), Penn & Teller’s magic show, and Jubilee! (a traditional-style Vegas extravaganza, and yes, the exclamation point is part of the title). Continue reading

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.

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.

On Sunday, March 11, a brush fire struck in the Anaheim Hills area. It was controlled relatively quickly, and by the next morning, the smoke had settled into a blanket of haze over Orange County.

For contrast, here’s a shot from a few weeks earlier (February 23), when it was unusually clear. This was taken from a park in the Quail Hill area of Irvine, looking across the Saddleback Valley from the south toward the same range of hills seen on the left of the picture above.

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.)

Yesterday, the Los Angeles Times ran an article on Justice Antonin Scalia and how his opinions may represent the majority as the Supreme Court hears cases about race, religion, abortion and campaign finance. Apparently, conservatives are really looking forward to the possibility that the court might restrict abortion, outlaw affirmative action, strike down the separation of church and state, and get rid of limits on campaign finances.

In other words, conservatives are hoping for a bunch of activist judges to legislate from the bench.

Below the second page of the article, there’s a short bit about Senator John McCain appealing to the religious right by saying he wants the court to overturn Roe vs. Wade…but that he doesn’t like judges who legislate from the bench. Sorry, Senator, you’re going to have to pick one or the other.

I liked McCain back in 2000. He seemed to be a moderate Republican with some integrity, and a more interesting person than Al Gore. Over the last year or so, he’s leaned more and more rightward. Either he’s changed his views, or is finally showing his true colors, or he’s sacrificing his integrity for power. In none of those cases would I want him as President.
