Green lasers

We bought a bright green laser a few months ago after reading that dogs (and some cats!) will chase them even more readily than the older red laser we already had. The new laser proved to be a great toy for the pets, exactly as advertised — just shine that green dot anywhere on the floor and watch your furry friends have a ball chasing it.

However, when reading an article about air safety, I discovered that there was an entirely different use for these things — you can use it to point out features in the sky. Instead of pointing with your finger vaguely in the direction of Orion's belt, you can point it out directly with the laser. I tried this on a recent evening, and it works stunningly well. I also tried our older red laser, and it worked, but not nearly so well. I'm not sure if that's due to the power difference (the green one is four times more powerful) or something abou the wavelength, or both differences combined. But whatever the underlying physics, the fact is that with the green 500mw laser, you can point out features in the heavens as easily and as precisely as you can point to items on a printed page...

But read the article I linked to above to find out some reasons to be careful with them!

Iraqi perspective

Iraq the Model is one of my favorite Iraqi blogs, not the least of which is because Omar (the blogger) has a talent for expressing his feelings effectively in English. In a rant today, Omar lays into the nay-sayers who deny that Iraqis are better off without Saddam and after the war. An excerpt:

There are actually a million stories I can tell to make a comparison between pre and post-Saddam Iraq and to show how dramatically life has improved since April 2003 and the list doesn't necessarily start from the security which is much better off now than under Saddam who murdered 3 million Iraqis during his reign; a figure that dwarfs any post-liberation body count or my salary as a dentist which increased by a hundred folds and doesn't end by the huge change in the Iraqi army that changed from a tool of repression for both, the conscripted soldiers and the civilian population to a security preserving tool that young Iraqis volunteer to join.

Technology and communications had their share too; we moved from a country where your e mail needs two weeks to pass through the filters of the Mukhabarat to a country where people like me can publish their thought to the entire world by a click!

And as our author of honor here is British I'd like to add that before April 2003, being caught while listening to the anti-war BBC radio could throw the listener in jail for indefinite time.

Anyway, if I wanted to talk about every single positive change, I should probably write a book about it as a blog post can't hold all that information.

By European and American standards, Iraq could be considered hell on earth and I agree; life is difficult here, really difficult for many Iraqis and it would be almost impossible for a European or an American but the question here is this: is it more difficult now than under Saddam?The answer is NO.

But please read the whole thing!

Supporting the troops

From DefenseLink.mil, this very nice story (By Sgt. 1st Class Doug Sample, USA,American Forces Press Service):

WASHINGTON, April 24, 2005 – Servicemembers all over the world, especially those in Iraq and Afghanistan, got a big show of support from the country music capital of the world April 23 when Grand Ole Opry faithful stood with posters and shouted on the count of three before television cameras: “America Supports You!”

The special broadcast was part of the Defense Department’s “America Supports You,” campaign, which aims to showcase and communicate American support to the men and women of the armed forces.

The Grand Ole Opry Live program, which this week was hosted by country music legend Dolly Parton, was aired live on the Defense Department’s American Forces Television.

The program is fed to 177 stations throughout the world, including a live feed to Baghdad that aired about 4 a.m. local time.

Welcoming the overseas audience, Parton yelled out in her familiar country voice, “Goooood morning Baghdad!”

“I don’t know what they are doing up that time of morning,” Parton chided the audience. “I guess working.”

Performers at the live show, which included Parton, The Grascals, Hanna-McEuen and Jo Dee Messina, dedicated songs to servicemembers. And in the audience, Parton welcomed a surprise special guest on stage, the newest member of the Grand Ole Opry family, Defense Secretary Donald Rumsfeld.

After thanking Parton, the other artists and country music lovers from around the world for supporting the military, the secretary presented a special message to troops watching the program overseas and those listening here at home.

“I’d like to say to each of them, volunteers all, ‘Thank you so much for your service to the country. And thank you to your families and your loved ones as well because they too sacrifice, and we appreciate them,’” he said.

“And each of the men and women in uniform needs to know that the great sweep of history is from freedom, and they are on freedom’s side. They are on that side, and it’s the right side,” he said. “So God bless them, and God bless their families, and God bless this wonderful country of ours.”

On stage, Parton also reminded the secretary that May is Military Appreciation Month at the Opry. During May, she said, servicemembers and their families will be given free admission to the Opry Live show.

“Come see us in the month of May and you can get in free. We love free don’t we,” she said.

Parton told the audience that she was happy to host the show in partnership with the Defense Department’s America Supports You campaign “to show our wonderful soldiers all over the world how much we appreciate and support them.”

Arab Parallel Universe

At Rantings of a Sandmonkey, there is a wonderfully funny post about how Arabs view the world. The thesis is that the Arabs are operating not in the "real" universe, but in a parallel universe (the Arab Parallel Universe, or APU), where all the same events happen but the reality, causes and reasons are different. The APU has 7 rules:

1) Arabs never make mistakes, and they rarely lose wars.
2) The Zionists and the Americans are always to blame for everything that is wrong in the APU.
3) If there is any credit at all that can be contributed to Arabs in any way, they will take it.
4) Good leadership is inversely related to how US-friendly a leader is!
5) Any media that is not the official state-owned media is filled with Zionist, Jewish, American, Christian, imperialist, anti-arab influences and they LIE ALL THE TIME!
6) There is really no need for elections in the APU, because Presidents and rulers are presidents and rulers for life.
7) The only viable alternative candidate to the current leader or president is this current leader or president’s son.

But read the whole post — Sandmonkey is a budding Arab Steyn...

Eagle nebula

...from the Astronomy Picture of the Day:

Newborn stars are forming in the Eagle Nebula. This image, taken with the Hubble Space Telescope in 1995, shows evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. The giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillars' end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseries of dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years away.

Infrared Moon

The Astronomy Picture of the Day brings us this view of our moon:

In September of 1996, the Midcourse Space Experiment (MSX) satellite had a spectacular view of a total lunar eclipse from Earth orbit. SPIRIT III, an on board infrared telescope, was used to repeatedly image the moon during the eclipse. Above is one of the images taken during the 70 minute totality, the Moon completely immersed in the Earth's shadow. Infrared light has wavelengths longer than visible light - humans can not see it but feel it as heat. So, the bright spots correspond to the warm areas on the lunar surface, and dark areas are cooler. The brightest spot below and left of center is the crater Tycho, while the dark region at the upper right is the Mare Crisium. Of course, this Sunday's lunar eclipse will not be a total, or even a partial one. Instead, the Moon will glide through the subtle outer portion of the Earth's shadow in a penumbral eclipse of the Moon.

What they don't explain is why features like Tycho are warm, nor (in a brief Google search) could I find any reference that did. During an eclipse, it can't be solar reflectivity. My best guess is that the bright infrared areas are places where higher-than-average amounts of solar radiation is absorbed, thus warming the rocks. During an eclipse, these places would appear "hot" (or bright) in infrared...

An Iraqi perspective

Ali of Free Iraqi — always an interesting read — has a fascinating new post. In it he develops a theory about how Iraqi (and Arab in general) perceptions are formed. He notes that Arabs tend not to ask questions, but to defer instead to authority, whereas Americans ask lots of questions. He then uses this obeservation to infer how Iraqi perceptions have developed. An excerpt:

After Saddam was toppled most Iraqis took a sigh of relief, "Now finally someone sane is going to run things here". They did think of America as a sane power totally replacing a mad one, at least for a while. I say they were relieved not just because they got rid of Saddam, as that meant incridible joy not relief. But It's been also a relief because it was scary to think that your fate is in the hands of an insane man while you can't do anything and you're not even used to such a huge responsibility.

But the Americans did not want to replace Saddam. They did not want to run things the way they wanted without sharing the responsibility with the people, even if they thought their management could fix things and even if this was for a transitional phace.An iron evil fist was gone but it was not replaced by an "iron good fist" as many Iraqis wished, and things collapsed in a place that has been ruled with extreme force for decades when people were given freedom.

This is one of the main reasons why many Iraqis were and still are disappointed with America. No, these Iraqis do not hate America as most like to think, they're just disappointed with her for not fitting the image they had in their minds; the just tyrant that should've taken full responsibility for some time until they could find their own just tyrant who would make their life much better without forcing them to share a burden and a responsibility they never thought it was among their duties as citizens.

Read the whole thing, not only for the perspective on Iraqis, but also for the window into how Americans look to some other cultures...

A bad day

A remarkable story — a tribute, really — from Villainous Company, about an attack on a Marine base in Iraq. An excerpt:

From atop his lookout post on the Iraqi-Syria border that day, Corporal Joshua Butler must have wondered briefly if he'd been transported to Hell.

A white dump truck came careening towards him, bursting through a raft of wired-together abandoned vehicles. But that was only the beginning of what most people would call a bad day:

Butler, 21 and an Altoona, Pa., native, fired through the windshield of the first suicide bomber as he rammed a white dump truck through a barrier of abandoned vehicles the Marines had improvised. Barreling toward the camp's wall, the truck veered off at the last moment under volleys of Butler's gunfire."I shot 20 or 30 rounds before he detonated," he says. Knocked down by that blast, with bricks and sandbags collapsing on top of him, Butler struggled to his feet only to hear a large diesel engine roar amid the clatter of gunfire. It was a red fire engine, carrying a second suicide bomber and passenger. Butler says both were wearing black turbans and robes, often worn by religious martyrs.

Amid the chaos of that first bomb blast, supported by gunfire from an estimated 30 dismounted insurgents, the fire engine passed largely undetected on a small road that leads from town directly past the camp wall, according a Marine report.

"I couldn't see him at first because of the smoke. It was extremely thick from the first explosion," Butler says. When the fire engine cleared the smoke, it was much closer than the dump truck had been.

As the driver accelerated past the "Welcome to Iraq" sign inside the camp's perimeter, Butler says he fired 100 rounds into the vehicle. The Marines later discovered the vehicle was equipped with 3-inch, blast-proof glass and the passengers were wearing Kevlar vests under their robes.

Rover trouble

New Scientist magazine is reporting that the Opportunity rover (on Mars) has lost the ability to steer its right-front wheel, one of six. This is more of a nuisance than a real problem, though it will make fine maneuvering more challenging. The rover has new software designed explicitly to deal with this situation, uploaded a few weeks ago in anticipation of some of the moving parts wearing out.

Both rovers are continuing to do good science, 16 months after landing (and 13 months beyond the "warranty" date!).

Pope reaction

It's only been a day since the election of Cardinal Ratzinger to become the next pope — Pope Benedict XVI. I'm about as non-Catholic as one can possibly get, but the reaction of (mostly) the Catholic world to Ratzinger's election has proved unexpectedly interesting to me. And the reasons have nothing whatsoever to do with religion.

The reaction tends to be highly polarized — people are either thrilled or they see Ratzinger as something approaching the harbinger of the apocalypse. The latter reaction is the one that I find interesting, because of its basis. For the most part, the people who are objecting to Ratzinger's elevation do so because they object to his orthodoxy. In other words, they are unhappy because the newly elected pope is committed to retaining the church's long-standing moral standards and resulting policies.

These people who are so appalled at the selection of Ratzinger remind me very much of political liberals in the sense that they do not seem to believe there are any moral absolutes. For example, many of the appalled Catholics would like to see the church change its stance on contraception — even though, quite clearly, doing so would violate one of the church's most clear-cut moral standards: the sanctity of human life. For the church to change its stance, it would first have to acknowledge that its definition of what is moral could change over time. And the appalled Catholics are ok with that. Similarly, the political liberals in the U.S. are perfectly ok with the courts "re-interpreting" the Constitution to fit whatever the belief-of-the-day is.

If I were Catholic, I would be firmly amongst those who were thrilled by Ratzinger's elevation. My reasoning would be that the church represents, more than anything else, a moral framework that I subscribe to — and Ratzinger is a defender of that framework. And I suspect that my political conservatism is grounded in similar patterns of thinking — identification of a political framework that I subscribe to, and a desire to defend that against erosion.

ScrappleFace nails this issue perfectly. And John Hinderaker, in a current Weekly Standard column, makes the point somewhat more seriously:

The left makes no secret of its intentions where the Constitution is concerned. It wants to change it, in ways that have nothing to do with what the document actually says. It wants the Constitution to enshrine its own policy preferences--thus freeing it from the tiresome necessity of winning elections. And how will the Constitution be changed? Through a constitutional convention, or a vote of two-thirds of the state legislatures? Of course not. The whole problem, from the liberal perspective, is that they can't get democratically elected bodies to enact their agenda. As one of the Yale conference participants said: "We don't have much choice other than to believe deeply in the courts--where else do we turn?" The new, improved Constitution will come about through judicial re-interpretation. It only awaits, perhaps, the election of the next Democratic president.

Fuelbreak

I had no idea, yet this fuelbreak is quite close to our home — basically just over Gaskill Peak. For those of you who may be unfamiliar with the Carveacre area, this little community is just east of Loveland Resevoir and just northeast of Gaskill Peak (which forms the eastern wall of Lawson Valley).

The Forest Service's description:

Using mechanical treatments and prescribed fire, the Forest Service is creating a defensible zone on National Forest System lands around the community. On private lands, the Carveacre FSC is reducing the fire hazard by mastication, hand clearing and chipping. The Carveacre FSC has also prepared a detailed community protection plan that includes evacuation routes, safety zones and emergency notification phone trees. The Carveacre FSC has been awarded community protection grants over the last two years.

The Carveacre community defense zone is a key project linking the Japatul and Horsethief Fuelbreaks. These fuelbreaks provide a strategic line of defense for the communities of Carveacre, Lawson Valley, Alpine and Japatul Valley.
