Luckiest. Tourists. Ever.

Every Saturday and Sunday, the Visitor Information Station at the Onizuka Center for International Astronomy on Mauna Kea offers free guided summit tours. There are, of course, some restrictions for liability purposes - you can't go if you're under 16, pregnant, have a history of heart or respiratory problems, have been scuba-diving in the last 24 hours, or have failed to bring a vehicle with 4 wheel drive and low-range gearing (unless you can talk someone who brought one into giving you a ride, of course).

So, obviously, scuba-diving pregnant teens with heart problems and sports cars are right out.

Folks show up at the Visitor Information Station, watch the "First Light" video about the mountain (which debuted on PBS Hawaii in June), then we all caravan up with a ranger along for safety, tell them about the mountain, the geology, Hawaiian history, culture and religion, and oh, yeah, the telescopes. And, we actually go into two of the observatories, which is, well... two more than most people go into?

Anyway, on some (though not all) Saturdays and Sundays, I'm one of the guides. Earlier this month I finished my training and started working on my presentation, eventually devising a single page that can serve as both my "cheat sheet" and a "take-home" for tourists, covering all the observatories on the summit as well as some cultural and natural sciences bits. And earlier this week, I got my 4WD test out of the way, demonstrating that the 5-mile, 12-percent-grade washboard we call "road" wouldn't kill me or people in my immediate vicinity.

Ordinarily, we talk about geology, culture and stuff like that outside the Keck observatory, go inside the visitor gallery to talk about Keck, briefly go into a viewing area in one of the domes and talk there, come back out, drive over to the University of Hawaii's 2.2-meter telescope, talk in the lobby, climb the stairs, talk in the visitor gallery, go into the dome, talk there, go into the control room and talk a little there while people take pictures, then go out onto a balcony sort of thing outside for a really great view and a little more talk, then go back down and give them parting guidance about sunset, getting down the mountain, etc.

Today, a few strange things happened.

First, our senior guide, Jonn Altonn, called in sick. That left me (just barely qualified), my friend Kent (a fairly recent volunteer who'd never been to the summit before, but wanted to learn), our cultural guru Koa in lieu of Jonn, and our senior ranger Kimo (who's also a practitioner in the Hawaiian religion) along for safety. Koa gave everyone printouts of some Hawaiian chants and their translations, and did a half-hour cultural presentation outside Keck, including two audience-participation chants, an introduction of Kimo, Kimo talking about stuff, and Koa and Kimo doing a third chant together. It was... very cool. And I videotaped it, yay.

While I was talking about telescopes, someone decided it'd be a very good time to silently spin Keck 2's dome around, so everyone got to see that. When we went into the Keck 1 dome, technicians were actually working on stuff above us, rolling instruments out to the scope for the night's viewing. Finally, NASA's infrared telescope facility dome was open when we got over to the UH scope, so people were able to get photos of that, too.

All in all, a most excellent adventure. And (scarily?) some tourists somewhere have video of me explaining all manner of silly things. :)

Must keep telling myself it's just hardware

Sunday: I notice a puddle on the concrete floor in front of the basement toilet. My daughter says no, it's not pee, it's water. Odd. I ask her whether she spilled water, and she says yes. I wipe it up.

0-dark-30 Monday morning: Her quilt got a little pee on it - oh well, she's four; these things happen. I take it down to the washer, and hey, that puddle's back. And... bigger. Uh-oh. All I can say for sure right now is that it's dripping off the little piece of flexible hose/pipe that goes into the toilet. Towels and a drip container are deployed. I'll investigate further, later today.

Between this, the dead EZQuest drive, the mostly-dead iBook LCD panel, and such, I'm wondering whether maybe I'm just a person things go to when they're going to die.

Sunset above Mauna Kea


The upper reaches of Mauna Kea are usually above the clouds, but occasionally high clouds get quite a bit of color after the sun drops behind the mountain's numerous cinder cones or
 pu'u. This photo was taken from near the mid-level facilities above 9,000 feet, across a "saddle" ridge between two cinder cones. It's a 1/10-second f/4 exposure from a Canon PowerShot S20.

Here be Dragons

For those who haven't met her yet, this is Lizzy, a Green Iguana (Iguana iguana) that lives at the Panaewa Rainforest Zoo in Hilo. She's a regular at the petting zoo, and I take her picture pretty often. This was shot with my Canon EOS Elan 7 35mm SLR, using a +4 diopter close-up lens and Kodak's C-41 process black and white ISO 400 film. I didn't remember that I had black and white film in the camera at the time, but even if Lizzy looks less colorful than usual this way, I liked the detail.

It's that time of year.

Yeah. My birthday. The 21st of July. 33, this time around. So what do I want?

Well, there are some things that always make the list.

World peace would be nice. I keep asking for it, and everybody keeps getting me other stuff. Maybe if you all team up, you can get it for me?

I haven't been known to refuse cash. Especially not lately. Predictable cash flow is high on my list of wants right now. Even if it's from a job.

Other than that, it's mostly about "the vision thing." Optics, you know?

I'd like a Canon EOS-1D Mark II digital SLR body. But oh, those are $4500 or so. The EOS-10D, similar to my 35mm Elan SLR, is only about $1500. But... yeah, I'd settle for a Digital Rebel (EOS-300D) that's only around $800.

Did I mention I'm listing the expensive things first?

Next most expensive is the Canon EF 75-300mm IS zoom lens. That's the image-stabilized one. The IS lens on one of my digital cameras spoiled me. This is probably around $400, give or take some.

Then there's "a telescope." I'm a little unclear on this, really, since I might be traveling for work and wouldn't be able to take it with me. Orion's $199 XT 4.5 dobsonian-mount newtonian is a good one that everyone in my family could easily use, but if it were just for me, I'd want something with a manual equatorial mount that could be upgraded to motor drive down the road. So... maybe just send money and let me worry about which one to get. :)

Then there's the Oberwerk 9x60 binoculars, which are about $100-$120.

Oh, and one other thing... George W. Bush, I know you probably don't remember me, since we haven't seen each other since November of 2000 and things were pretty hectic back then, but if you're reading this, I was thinking it'd be really cool if you could take a break from the whole D.C. scene for a while and come out here. I know you really like vacations, and you haven't really gotten any quality time out here during the last few years. Bring the family and Mr. Cheney along - he can relax, and I'll take you and the Secret Service guys hiking, snorkeling and stuff. Leave John McCain and Colin Powell in charge - they'll take good care of the country while you're away. No need to hurry back... several months should be about long enough...

Our Friend, the Meter

This evening, I learned that one meter equals 39.3700787 inches. While this may come as no surprise to some people, it was one to me - for years, I had mistakenly believed a meter was 39.77 inches, and now I know it's basically 39.37.

Of course, I'm not alone in my confusion. A bit of research on Google revealed quite a few different conversions from meters to inches. Here are some of them:
Once again, the correct answer is right around 39.37 inches. Remember that - it'll be on the quiz!
Updated 6/24: More than a few people have kindly pointed out two things:
  1. When rounding to 1 significant digit, 40 inches is actually "correct," as is 39 when rounding to two, and 39.4 when rounding to three. So the USDA and Navy, along with the quilting folks, are not technically "wrong." The H2WTech folks, however, list 1 meter as 39.40 inches - four significant digits - and are therefore still wrong, as are the folks at Fife Products who list it as 39.0 inches - three significant digits.
  2. More usefully, there is, of course, a precise conversion factor of 1 inch = 2.54 centimeters. That's the correct way to convert things - inches x 2.54 / 100 = meters; meters x 100 / 2.54 = inches. Fair enough. This does, though, make me wonder why numerous sites listing metric conversion factors include both the precise one for inches and centimeters and somewhat arbitrary ones for inches and meters.

Advice on Ivermectin

I've seen a lot of talk about the anti-parasitic drug Ivermectin recently.  Specifically, about people taking veterinary formulations in...
