FEMA Anger

But perhaps not in the manner you're thinking. Check out this report from FEMA member Jodi Witte:

Dear Friends and Family,

I just got home from 15 days in New Orleans and the surrounding areas. I am tired, and I am emotional. But mostly I am angry. I am angry at the news - the TV stations, the newspapers - for what I view is a grosslymisrepresented placement of blame. For those of you who know me, you know I work for FEMA as an "intermittent employee" of a disaster response team. My team, called VMAT or Veterinary Medical Assistance Team, is partof the response branch of FEMA known as the National Disaster Medical System.

Let me tell you how "awful" FEMA's response was from someone who was there on the front lines working for FEMA.

President Bush declared a state of emergency prior to Katrina's landfall due to its strength and location. This is not normally done before a hurricane makes landfall. Damn good work by George W in my honest opinion. This opened the door for our federal teams to pre-deploy assets in nearby locations so that we were ready when Katrina did hit. I wascontacted by FEMA before the hurricane hit, asking for my availability and to place me on alert. Many teams were moved into the region including 2 VMAT teams. My team was mobilized immediately after landfall and I arrived in the area before New Orleans had completely filled with water,before we even realized how bad it was truly going to be. FEMA responded immediately and with unprecedented numbers of responders. There were DMAT teams inside the Super Dome before the levee broke. Never before had so many FEMA teams and personnel been sent into a disaster.

One thing you must understand, the DMAT, VMAT, and DMORT teams that make up the National Disaster Medical System are NOT "first responders". Our job is to supplement overwhelmed communities if needed. The initial responsibility lies with the state. If they become overwhelmed in the aftermath of a disaster where their local hospitals, medical, veterinaryand mortuary assets cannot handle the magnitude of the disaster, we come in and augment their resources. It takes 24 to 48 hours to mobilize the federal assets in normal circumstances. We come from every state in the US, leaving our jobs and families behind at the drop of a hat to helpwhere ever it is needed. Our cache of equipment and medical supplies must either be moved from our home base or from the federal warehouses in Maryland by truck or plane. This takes time. But we were there before Katrina hit and many more arrived immediately after even before knowing the full scope of this disaster.

So why is FEMA being blamed? I'm not exactly sure. I really am not. Yes, FEMA was overwhelmed. God sakes how could it not be? This hurricane has been the largest natural disaster the US has had on record. Nothing can compare. We train and train for almost anything. We try to be ready. But no one was ready for how bad this truly was. I am sure there were some bad decisions made high up, of that I cannot deny. It was a logistical nightmare to get the teams placed and the supplies sent in. Some stuff arrived too late. But, seeing how hard the FEMA employees worked to help the people and animals of Louisiana, Mississippi, and Alabama it makesme angry and very, very sad to hear us put down so bad on TV and in the news.

One day, just a couple days after New Orleans was under water, I was stationed in the New Orleans airport. This is where I was the first week. The airport was where all the buses and helicopters that were rescuing people from the city brought them first. They came in the thousands to the airport and went through lines holding their last bit ofpossessions, which included a small amount of clothing or keepsakes and often times their pets. Yes, they got to bring their pets with them on the buses and helicopters. I know because I was there. I saw them. They came in and were triaged by FEMA medical personnel. Minor injuries or illnesses were treated with the utmost care and love by FEMA DMAT teams and then they took their place in line through concourse C to board planes to shelters where they could receive follow up medical treatment. The very ill weremoved into the D concourse area for more thorough medical care and support in a true MASH hospital set up right there inside the airport. I walked through this area frequently and watched as DMAT members held the critically and gravely ill peoples' hands, cared for them, helped them in so many ways trying to save their lives and to comfort those who could not be saved.

I walked through feces, urine, blood and vomit covering the floor of the airport. I watched custodians working tirelessly to clean up the floor even though it was soiled again as soon it was cleaned. People were handed water and food as soon as they arrived. Those who were well, movedthrough an endless line to concourse B to board both commercial and military planes going to shelters in other states. I walked the lines of concourse B, C, and D as did other members of my VMAT team to provide any needed veterinary care to the pets who were evacuated with theirfamilies. We cared for stray animals that arrived at the airport too. See, the coast guard and military helicopters were picking up stray animals if they had room when they would rescue people from the city. FEMA personnel did everything possible to comfort and care for the peopleof New Orleans. I know because I was one of them, and I did everything I could for them, and I saw with my own eyes what the others were also doing.

This is a photo on the FEMA website. What you don't see here is that this little dog is sitting below the hospital gurney of his master who was critically ill inside one of the DMAT MASH tents. I walked through this medical tent to check on the dog with a couple other members of my VMAT team. The nurse had given the dog a dish of water and was feeding himsome crackers. We promised the man we would bring back some food for his dog. He was very thankful as he laid there with IVs going. I returned a few minutes later with one other member of my team, bringing a Ziploc bag of dog food. When we arrived they were moving him to a different stretcher because he needed to be medivac'ed out on a helicopter formore intense medical care. The helicopter pilot told us he cannot take the dog unless its in a crate. I stepped up to talk to the very ill man. I asked him if he would let me care for his dog while he went to the hospital. He grabbed my hand and had tears in his eyes as he begged me to help him take his dog with him because it was all he had left in the world. There was nothing else. I looked into this man's eyes as he cried. He was a middle aged white man with cuts and scrapes all over him. His face was puffy and feverish with infection. I then looked at the DMAT nurse and the Coast Guard pilot. Both looked back at me with very graveexpressions and each asked me to please find a crate for the dog so he can go with the man. My teammate and I both knew right then that this man may not make it and we had to make sure he got to spend as much time as possible with his dog. There was no way we were going to make him leave his dogbehind. We took off running and found an empty crate. It was a bit too small for the dog, but would work temporarily. We returned and found the pilot waiting for us with the man. Once we got the dog in the crate and on the stretcher with the man, he again took my hand and thanked us as we cried together. He said "you have no idea what you have done for me and I will never forget it" Then he was wheeled away toward the waiting helicopter.

So, at the end of this day...a 29 hour shift that I spent at the airport, I arrived back at our bunk location - a building on the campus of LSU where we slept on the floor - and I got to see the news on one of the cable networks. I was absolutely outraged at the reports of the lack ofresponse by FEMA. I changed to another cable news network and saw the same thing there. What they don't mention when they talk about FEMA is the people that make up FEMA's response, working countless hours, pouring their very heart and soul into this response despite being slammed andcriticized all over the news.

I cried with sadness and anger at how we are viewed all over the world. I am a FEMA responder who cannot wear my FEMA badge in public in Louisiana because everyone thinks we are so terrible. Do they even yet mention how hard we have worked for the people and animals of Louisiana? No, maybethey never will.

Just yesterday the radio was criticizing the fact that FEMA had so many trucks filled with water and supplies that were just sitting somewhere and was costing $600 per day each to sit and wait. Does anyone realize this is the right thing to do? There is already a tremendous amount of water and supplies in the areas. The reason there are trucks waitingfull of more supplies and water is so they can move at a moments notice to where ever they are needed at any time. Would they rather have the extra supplies sitting in a warehouse where they would have to wait to secure trucks, then load the supplies and water, then move them out? Hell no. They complain about the lack of quick response by FEMA but yet don't get the whole concept that these supplies and water sitting in trucks ready to go is for quick response and now they criticize FEMA readiness without realizing it. The contradictions in the news is ridiculous.

Now 13 days after I first saw the news reporting how awful FEMA is, I still remain proud to be a member of FEMA, and I am proud of the work I did in New Orleans and I am proud to work for the federal government headed up by a strong and brave president. It was not easy, and things may not have gone perfectly, but we did and continue to do amazing workthere even if no one knows it because they will only look at what went wrong instead of so much that went right.

There are lots of hoaxes running around on the Internet, so before I posted this I did a little research on the web. It appears to me to be a legitimate story, written by a real person. In fact, here's some information about that person (Jodi Witte) that you might be interested in: Jodi Beck Witte is a veterinary technician and weapons of mass destruction specialist for a FEMA disaster response team and manages an animal health website. You can also email Jodi directly.

Lookin' Good!

Reading Big Lizards (a highly recommended activity) this morning, I discovered a new poll on Schwartzenegger's five initiatives that has much more encouraging results than anything I've seen heretofore. Dafydd (how the heck do you pronounce that, anyway?) tells the tale of a new SurveyUSA poll that shows all five propositions in the "win" column, several of them so far in the win that even the undecideds plus an outcome at the worst side of the margin of error wouldn't change the results.

That's more like it!

Prior to seeing this poll results, most of the news I've read about the propositions was along these lines (excerpted from the September 5 Sacremento Bee):

Two of the three initiatives Gov. Arnold Schwarzenegger has proposed to fix California government are losing badly and a third is trending in the same direction - toward defeat, according to a new Field Poll.

A fourth initiative aimed at the financial heart of Schwarzenegger's union-funded political opposition continues to hold a substantial lead, although a huge bankroll of labor-generated campaign cash poses a threat to the measure.

Which I found pretty depressing; willing sheep to the slaughter and all that.

I'm feeling much better after reading Dafydd's post and the poll results he pointed to. Dafydd thinks the differences in the poll results can be explained by poor poll construction:

This is truly excellent news. Previous polls had shown the measures limping towards defeat, but in each case with very large "undecided" respondents. I almost blogged about this earlier, but I wasn't sure how to explain it: the problem in the earlier polls were lengthy, hard-to-parse questions and no explanation of any of the measures. I was certain that most people's reaction was "huh? I don't get it," and that was artificially lowering the Yes vote.

Well, Dafydd may well be right about this. I'm no expert on polling, but it's obvious that how a poll question is worded can influence the results. For example, one could ask about proposition 74 like this (as the CTA's ads are doing):

Do you support proposition 74, which allows administrators to dismiss teachers for no reason at all, without consulting with parents?

Or like this:

Do you support proposition 74, which allows administrators to dismiss poor teachers instead of forcing schools to keep bad teachers no matter what they do (tenure)?

I'm pretty sure those two questions would get different results in a poll!

Whatever the reasons for the differences between this new SurveyUSA poll and the earlier polls, this is very hopeful news (assuming, of course, that the new poll is more accurate). It put a smile on my face for the morning!

Lunar Librations II

After my last post on lunar librations, my dissatisfied friend was still dissatisfied. He said:

Okay so my intuition failed me wrt to the major component of lunar librations, but the pictures should still be different since the close one is below the equator and the far one is above it...

My friend is assuming that apogee and perigee correspond with the points at which the moon is furthest from the ecliptic. I had a vague memory that such was not the case, but I couldn't remember the details. A little Googling research today got the answers.

It turns out that the moon's apogee and perigee are not always the place where the moon is the furthest from the ecliptic. There are two phenomena that determine this. One is called "nutation", which is the rotation of the moon's "node line" around the Earth (the node line is an imaginary line drawn between the two points in the moon's orbit where it crosses the ecliptic). The moon's nutation period is 18.60 years, direction to the west. The other phenomenon is the rotation of the "line of Apsides" (the line between the moon's perigee and apogee); it rotates in the opposite direction, once every 8.85 years (reference, more info).

If (big if!) I'm juggling all these phenomena correctly, then the apogee and perigee move with respect to the points at which the moon is the furthest from the ecliptic on a cycle of 18.60 - 8.85 years; in other words, every 9.75 years. So ... once each 9.75 years, my friend's assumption would be correct; in between he'd be wrong to some degree. One interesting consequence of this is that every 9.75 years the maximum longitudinal libration would be coincident with the maximum latitudinal libration. I was unable to confirm this on the web (when the line of Apsides was coincident with the node line).

In the course of researching this, I came across an article that talks about another consequence of lunar librations; one that I had not considered.

Imagine you're an astronaut, and you're standing on the lunar surface. If you ignore librations, the earth is always at the same place in the sky, as a consequence of the moon always "turning the same face" toward the earth. But ... factor in librations, and you get an odd result: the earth, seen from the moon's surface, moves about in a little "box" in the sky. Seen from the lunar surface, the earth appears to be about 2 degrees wide. The box it moves around in is about 15 degrees wide in longitude, and 13 degrees wide in latitude. That's a fairly large motion, one that would be quite evident to a naked-eye observer. From what I know (now!) about the librations, that must be a very complex motion in that box. And to my surprise, I was able to find (on the web) a computed path, illustrated, and that's the picture you see above right.

Quote for the day

I hate newspapermen. They come into camp and pick up their camp rumors and print them as facts. I regard them as spies, which, in truth, they are. If I killed them all there would be news from Hell before breakfast.

Alika is one of our cats — our newest cat, as a matter of fact. You can read all about him, and be subjected to more cat pictures than any human should have to endure.

Pampas Grass

We have a couple of pampas grass plants in our front yard that are blooming right now. The picture at right shows the flowerhead of one against our beautiful blue southern California sky. I took a few photos of them this morning, and did a little research to find out about these beautiful plants; there were some surprises there! You can read about it at my pampas blogging page.

Mopey

You can count my wife and I amongst those with very strong attachments (some say unreasonably so) to their four-footed friends. In our case, that's two dogs (soon to be three, we hope) and eight cats. As their life span is so much less than ours, of course over the years we have lost some of those friends. More than is comfortable to remember. This has just happened to Dr. Bob and his family over at The Doctor Is In; they have just lost Smokey, their friend and companion of 14 years. Dr. Bob has posted an eloquent and touching ode to their friend and family member, displaying a talent for such things that I wish I could muster at such at time. Reading his post, you get a real sense of Smokey — and of just how much he meant to the family. One sample:

Mopey — as we always called him — was a special cat in so many ways. Possessed of the laid-back disposition so common to Persian cats, he spent the better part of his life sleeping on his back, and virtually all of the remaining hours looking for food. His culinary tastes were eclectic, to say the least — he loved vegetables, especially green beans, chickpeas, and broccoli. His few athletic moments were in such pursuit, stretched to full length to get at the butter dish on the top cabinet shelf, or trying to open the cabinet latch to get at his cat food, just out of reach. Unlike many cats who self-regulate their eating, Mopey was positively Bacchanalian in his dining habits — watching him eat was like witnessing a Roman orgy. Thus engorged, he would stagger over the to furnace intake vent, where he would loudly meow, the echo amplifying his voice as he envisioned himself the great hunter on the plains of Serengeti, roaring his satisfaction at the kill to impress the pride. Then he would stagger off to sleep in some bizarre configuration, spine twisted, legs in the air.

Dr. Bob's parting words put me in mind of my own thoughts and emotions on those occasions when we've lost one of our own animals, though Dr. Bob expresses it much better than I've ever been able to:

But we will hear it no more, and the loss brings tears to the eyes and a tightness to the throat. He was a friend, a companion, a member of the family, a source of many laughs and the particular aggravations which domestic animals seem uniquely able to inflict on their keepers. Our animals are our friends, God-given gifts to entertain us and foster our most affectionate and protective impulses. They are a blessing — but a blessing which departs all too quickly, their candles extinguished to remind us of our own mortality and the power of love and loss.

We love you, Mopey, and will miss you greatly. May your feline heaven bring you endless meals and long naps in the sun.

Amen to that, and our heartfelt sympathy to Dr. Bob and his family...

Dry!

The chart at right shows the temperature (°F on the left scale, red line) and relative humidity (% on the right scale, green line). For the past four days we've been below 20% relative humidity — much of the time below 10%!

This is extraordinarily dry even for the chapparal country, and it's been quite prolonged as well. Yesterday the wind was from the northeast for much of the day, indicating a Santa Ana condition, though the winds weren't high as they usually are in a Santa Ana.

This is a litle worrisome, as conditions like this are enablers for wildfires. There's one going on right now 150 miles north of us, and much the same weather conditions apply there. The longer the dry air continues, the longer the brush and botanical detritus has to dehydrate — and the drier that fuel gets, the more dangerous the conditions. When the fuel gets very dry — like it was before the Cedar Fires two years ago — then even the smallest spark can turn into a hard-to-stop fire. And because Lawson Valley hasn't burned for over 30 years, we have a lot of fuel on our hillsides.

Just today I ran across a map of San Diego County that was color-coded to show when each area had last burned. Lawson Valley is colored to indicate "1961-1970" — and if that's right, we've got 35 - 45 years of chapparal growth on our hillsides. Yikes!

Ponder Power

Jimmy Valentine is the Producer of the Roger Hedgecock Show (the only radio talk show you'll find me listening to regularly), where he's described this way:

Jimmy writes the Flash Fax daily, hangs around the Team Hedgecock office when he is not outside smoking. He barely graduated from high school and has no degree whatsoever. But for an old guy he's a little cute and often quite playful. He is mostly harmless and unproductive...he yearns for a permanent position in gummint where the wage and pension is great and the workload is light.

The "Flash Fax" mentioned above is an appoximately daily email that Jimmy writes. It's always interesting, often informative and insightful, sometimes inspiring, and occasionally hurt-your-belly funny. An example from today's edition illustrates at least some of the preceding claims:

THE POWER OF THE PONDER… not sure exactly where I picked up the power, most likely in Texas. We did several TV shows via satellite out in the Big Bend area back in the mid-80s and that area tends to be kinda mystic. I think it just come on me. I am not sure it’s a gift but it does strike often and just automatically re-sorts all the stuff in my head so that it makes better sense. A lot of dots connect in sudden fashion. I guess it’s like defragging your computer. And it seems to thrive out here in Dehesa Valley for some reason.

The Ponder can strike near anytime but it mostly happens during shaving in the morning or after the first Jack of an evening. Mind is wandering and suddenly “pop,” you set to pondering. You can’t turn it on and off, it happens.

It’s the Ponder that tells me that bankruptcy is the best and fastest way for SD City to resolve it’s financial crisis. I can’t vote there but the Ponder doesn’t abide by jurisdiction.

It’s the Ponder that tells me that it will be a good thing if Katrina victims sue local, state and federal gummints for not protecting them and demanding a 911 fund. And win. Cause we fire folks left over from the 2003 Wildfire Debacle are trying to class act a suit against the numbskulls that couldn’t quit the fire up in Ramona. So far court is saying you can’t sue the gummint. The Ponder sez that Jesse Jackson and his group will lead a court suit and a judge will bark when told to by Jesse and the gang. That’ll set court precedent and pave our way.

It’s the Ponder that tells me that if you are in favor of abortion then you are in favor of killing children and that is how it should be stated. Not, “I’m pro-choice,” but “I’m for killing kids.” And folks who have had abortions ought to be up front about it and proclaim, “I killed my baby,” and be proud in public.

It’s the Ponder that tells me that if you are opposed to big gas guzzling vehicles, you should ride the trolley, ride a bike to work or walk. And if you do drive you had better have 18 other folks in the car with you.

We’ve noted the Ponder many times in the flash over the years. The above examples are likely lousy but I hadda face the Ponder today and let it know that I know it exists…and that I ain’t scared of it……. tho I am awed. it’s a good power, tho sometimes I kinda wish I was able to see thru womens clothing instead.

I subscribe to quite a few email newsletters; this is one of them that I look forward to every day.

I've never met Jimmy Valentine, but he's nearly a neighbor of mine. He lives in Dehesa Valley, which is one ridge away from Lawson Valley, where my home is. Unlike me, Jimmy lost his home in the Cedar Fire of 2003 — we were just one ridge away from the same fate.

You can (and should!) subscribe to the FlashFax yourself (scroll all the way down), or you can peruse the FlashFax archives. Personally, I think Jimmy would make a great blogger; maybe we can talk him into it one of these fine days...

Priceless!

An honest man was being tailgated by a stressed out woman on a busy boulevard. Suddenly, the light turned yellow, just in front of him.

He did the right thing, stopping at the crosswalk, even though he could have beaten the red light by accelerating through the intersection.

The tailgating woman hit the roof, and the horn, screaming in frustration as she missed her chance to get through the intersection. As she was still in mid-rant, she heard a tap on her window and looked up into the face of a very serious police officer. The officer ordered her to exit her car with her hands up. He took her to the police station where she was searched, finger printed, photographed and placed in a holding cell.

After a couple of hours, a policeman approached the cell and opened the door. She was escorted back to the booking desk where the arresting officer was waiting with her personal effects.

He said, "I'm very sorry for this mistake You see, I pulled up behind your car while you were blowing your horn, flipping off the guy in front of you, and cussing a blue streak at him. "I noticed the 'Choose Life' license plate holder, the 'What Would Jesus Do' bumper sticker, the'Follow Me to Sunday-School' bumper sticker, and the chrome-plated Christian fish emblem on the trunk. Naturally, I assumed you had stolen the car."

Priceless!

Produce Blogging

The photo at right is not (I'm sad to say) one of mine. It's one of Rick Lee's photos, from his blog "On Location with Rick Lee". As he puts it in his blog's "About" section:

A commercial photographer in a small market. I love my work and I love the people I work with. How cool is that?

It's very cool. And what a pleasure for the rest of us, even those who (like me) can't help but be jealous of his talent for making memorable images of everyday things. His blog is on my "daily read" list just for the sheer pleasure of it.

APOD

APOD brings us...

Clouds of glowing hydrogen gas mingle ominously with dark dust lanes in this close-up of IC 1396, an active star forming region some 2,000 light years away in the constellation Cepheus. In this and other similar emission nebulae, energetic ultraviolet light from a hot young star strips electrons from the surrounding hydrogen atoms. As the electrons and atoms recombine they emit longer wavelength, lower energy light in a well known characteristic pattern of bright spectral lines. At visible wavelengths, the strongest emission line in this pattern is in the red part of the spectrum and is known as "Hydrogen-alpha" or just H-alpha. Part of IPHAS, a survey of H-alpha emission in our Milky Way Galaxy, this image spans about 20 light-years and highlights bright, dense regions within IC 1396, likely sites where massive new stars are born.

Hyperion

The Cassini-Huygens probe (which I've posted about many times) flew close by Hyperion a few days ago, producing the photo at right. As the mission web site says:

This stunning false-color view of Saturn's moon Hyperion reveals crisp details across the strange, tumbling moon's surface. Differences in color could represent differences in the composition of surface materials. The view was obtained during Cassini's close flyby on Sept. 26, 2005.

Hyperion has a notably reddish tint when viewed in natural color. The red color was toned down in this false-color view, and the other hues were enhanced, in order to make more subtle color variations across Hyperion's surface more apparent.

Images taken using infrared, green and ultraviolet spectral filters were combined to create this view. The images were taken with the Cassini spacecraft's narrow-angle camera at a distance of approximately 62,000 kilometers (38,500 miles) from Hyperion and at a Sun-Hyperion-spacecraft, or phase, angle of 52 degrees. The image scale is 362 meters (1,200 feet) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Check out the mission's web site, and also the imaging team's web site — both are full of interesting photos and information. As usual, click on the photo for a larger view...

Cute Animals

A friend sent these by email — a nice collection of incredibly cute animal pictures; 16 of them along the same lines as the sample you see here. You'll need a dose of insulin after viewing these!

Cheer

Reading one of James Lileks' columns, I discovered that he has a website he calls the "Institute of Official Cheer" that is, in fact, cheering to peruse. I particularly enjoyed the Gallery of Regrettable Food. From the Institute's page:

Here's where you can learn all about the Institute, its mission and its history. Not required reading to enjoy the Institute's fine products, but when you've burned through everything else, this might make a little more sense.

Don't miss it!

Rhma

A few weeks ago, Michael Yon first wrote about Rhma, a little Iraqi girl with a serious health problem. Later, he wrote about the help Rhma was receiving from many people — including a bunch of American soldiers — to get her back to the U.S. for the medical care she needed, but that their efforts were being thwarted by glitches and bureaucracy. Today he writes of some success breaking through the problems:

I wrote about it, knowing that if Americans knew that Rhma was stuck in Jordan, our good people would not let that stand. Once again, the good and generous nature of average Americans glimmered the moment they found the problem. People all over the United States took it upon themselves to call their congressmen and senators, many of whom interceded on behalf of a sick little girl who had faith that Americans would take care of her.

A nice story for a Thursday morning. And thank you, Michael Yon, for the fine job you're doing. I wish we had more like you...

Estonian Bogs

The photo at right is of a bog in Estonia, taken with a digital camera dangling below a kite. It's been entered in a contest on visualization in science:

With its intricate patterns within patterns and striking colors, the winning photograph bears a distinct resemblance to a fractal. But scale back — to about 150 meters above the ground — and the sinuous landforms of Estonia's Männikjärve bog begin to reveal themselves.

In the peat bogs of east-central and southwestern Estonia, autumn works a change in the color scheme: Cotton grass turns gold, hardwoods in surrounding forests turn orange and red, and pine trees remain silvery green. The bog water, in sharp contrast, stays an acidic brown. Geologist James Aber of Emporia State University in Kansas recognized the potential beauty of the landscape when he was collaborating with Estonian colleagues to study the glacial geomorphology and geotectonics of the region. But to capture it, he knew he'd need to get off the ground--or at least, his camera would.

The contest entry is here, and more on do-it-yourself aerial photography from kites is here. I'd like to try this myself, though I'm a little worried about how well the camera would survive!

From Boing Boing.

Well I'll Be...

"It is now commonly accepted that was not the right path. We are now trying to change the path while doing as little damage as we can."

So said NASA Administrator Michael Griffin on Tuesday, speaking about the space shuttle system in the International Space Station (ISS).

Oh, my. Over $100 billion down the rat hole, and finally someone in charge at NASA has the gumption to stand up straight and admit it.

As many of you know, this has been a soapbox topic for me for many years. I was skeptical of the space shuttle's design from its first public disclosure (anything that depends on 30,000+ hand-fitted and fragile ceramic tiles can't be reliable and cost effective!), and I got more skeptical as it became clear that the shuttle would miss every design target. The important misses: cost per kilogram to orbit, cost of development, and payload size: all of them were far off the mark, so far that the old Saturn V (Apollo's booster) would have outperformed the shuttle in every category.

But the shuttle program (and after it, the ISS) became political issues, with direction decided for reasons that had little or nothing to do with science, techonological development, or a national objective. The last time we saw those driving NASA was in the 60's; since then they've been more of an afterthought than a driver.

And I still don't know whether Michael Griffin will be able to change that, or even if he wants to. But his stated desire to get us off the shuttle/ISS treadmill and onto something more pragmatic (if I'm interpreting his words correctly) is a good start. I hope he can pull it off!

S.S. Estonia

Yesterday was the 11th anniversary of the sinking of the ferry S.S. Estonia. On September 28, 1994, it sank in the Baltic Sea. Over 800 people died that day, most of them Estonians, many of them children. Estonia is a small country; to have so many people lost is proportionally a huge disaster — roughly as if 115,000 Americans were lost in some horrible accident. The photo of the bell, at right, is from the monument on Tahkuna, Hiiumaa — the point of land within Estonia that is closest to where the ferry sank. The faces on the bell are in memory of the children who died that day. The reasons for the sinking are still very much in dispute, as you can see by this press report from yesterday:

TALLINN, September 28 (Itar-Tass) -- The relatives of those who perished in the Estonia ferry disaster of eleven years ago have urged another, independent investigation into what proved the biggest post-war loss of human life on the Baltic Sea.

The relatives voiced the demand in a resolution adopted at a conference in Tallinn on the eve of the tragedy that occurred in the Gulf of Finland on September 28, 1994.

“For the sake of restoring justice and coping with the moral duty to those dead and their relatives the investigation of the ferry disaster must be resumed under the supervision of an independent Estonian judge,” the relatives said.

The ferry disaster claimed 852 lives. There were 137 survivors.

A panel of investigators from Finland, Sweden and Estonia arrived at the conclusion that the ferry’s loss was due to faulty locks of the front gates of the ship’s car deck. Waves tore the gates away and the water that flooded the car deck caused a dangerous list. The ferry eventually capsized and sank.

Versions explaining the ferry’s loss are many – from collision with an unidentified submarine to conspiracy by smugglers of drugs and rare earth metals.

Many suspect there might have been an explosion on board. Evidence to this effect emerged after examination of fragments of the ship’s hull held at the request of Germany’s Der Spiegel magazine and the findings of expeditions that followed.

The Baltic countries have an agreement on declaring the hull of the ferry as a mass grave and on ending any further probes.

I've read a lot about the ferry sinking over the years. It happened to occur just a few days after my first visit to Estonia, and has been a frequent topic of discussion with my Estonian friends (none of whom had relatives on the ferry). Conspiracy theories swirl around the sinking, some sounding James Bond-ish, with secret agents using the ferry to bring back equipment purchased from the ex-Soviets. Encouraging the conspiracy theories are some acknowledged intelligence activities on the S. S. Estonia, including some that remain classified and therefore undisclosed. Wikipedia has a good article on the incident and its aftermath, with many links. City Paper (an Estonian publication) has a good chronology. Another interesting article that I've published on my blog is available here.

If you find yourself still curious about the sinking of the S.S. Estonia, try googling "estonia ferry sank 1994"; that got me 11,900 hits when I tried it this morning. That should cure anyone's curiousity!

Tethys Flyby

The Cassini probe is continuing its exploration of the Saturn system, most recently with flybys of Tethys and Hyperion. The photo at right is a remarkable close-up of the surface of Tethys; many more are posted on the Cassini site. On the flybys:

This week Cassini will play a doubleheader with two flybys of Saturn's moon's Tethys (Sept. 24) and Hyperion (Sept. 26). Cassini will be eye-to-eye with Tethys' giant Odysseus impact-crater. Cassini's close brush with the chaotic, tumbling Hyperion might tell us whether it is a rubble pile.

Scientists also hope to be able to shed more light on the following:

* The origin of the huge canyon-like feature named Ithaca Chasma on Tethys is not completely understood, but it might be related to the impact that created Odysseus.

* Hyperion's elliptical orbit and irregular shape influence its chaotic tumbling, which may have started after a giant impact with another body.

Snow Kiting

What do you do for sport if you're stationed on Antarctica? Snow kiting, of course:

Although we have an abundance of snow round here, one thing which we lack is mountains or even small hills. Not to be deterred, snowboarding types have been bringing their boards down here for years to try out skijuring. Skijuring is basically a cross between water-skiing and snowboarding, using a skidoo instead of a powerboat. You get on your snowboard, hold on to a rope that's tied to the skidoo and get pulled around at high speed!

This looks like a lot of fun to me! It's got speed, skill, and an exotic environment — the only thing missing is the wildlife...

Go read all about it, and check out the rest of the pictures, at 75 Degrees South.

Tarantula Hawks

In a post yesterday (Ants), I mentioned one of the beasties we have out here in the near-desert chapparal: the tarantula hawk. I think it's high time I introduced y'all to this little bug...

When I first saw one of these quite beautiful insects a few years ago, I was very curious as to what it might be. The photo at right (not mine!) doesn't do this insect justice at all. The body is a very bright blue, and the wings and antennae are an even brighter reddish orange color. They are bright enough to catch your eye at quite a long distance, and they're not a bit shy.

I could tell by examination that they belonged to the wasp family, and it didn't take much googling to find out what they were: members of the wasp family Pompilidae (spider wasps), in the genera Pepsis and Hemipepsis. I don't know the exact species we have here; apparently there are many species and they're difficult to tell apart. But very shortly after discovering what they are, I read this about them:

The sting, particularly of Pepsis formosa, is among the most painful of any insect. Commenting on his own experience one researcher said, "You will curse your mother for ever having you." Another described, "...immediate, excruciating pain that simply shuts down one’s ability to do anything, except, perhaps, scream. Mental discipline simply does not work in these situations." Yet another said, "It's not like things that make you swear and say bad things about somebody's mother. These things, when you get stung, you might as well lie down and scream. Why not? It takes your attention off the pain." Rightly so, it is lies almost at the top of the list in Schmidt Sting Pain Index. Although the sting is quite painful the effect is reported to last only a few minutes and is less lethal than that of the honey bee.

Now I'd never heard tell of the "Schmidt Sting Pain Index", but it didn't sound good. A quick look on Wikipedia got me this:

Schmidt Sting Pain Index or The Justin O. Schmidt Pain Index was created by Justin O. Schmidt, an entomologist. Having been stung by almost everything, Schmidt created (on his own time) an index to compare the overall pain of insect stings on a four-point scale.

* 1.0 Sweat bee: Light, ephemeral, almost fruity. A tiny spark has singed a single hair on your arm.
* 1.2 Fire ant: Sharp, sudden, mildly alarming. Like walking across a shag carpet & reaching for the light switch.
* 1.8 Bullhorn acacia ant: A rare, piercing, elevated sort of pain. Someone has fired a staple into your cheek.
* 2.0 Bald-faced hornet: Rich, hearty, slightly crunchy. Similar to getting your hand mashed in a revolving door.
* 2.0 Yellowjacket: Hot and smoky, almost irreverent. Imagine WC Fields extinguishing a cigar on your tongue.
* 3.0 Red harvester ant: Bold and unrelenting. Somebody is using a drill to excavate your ingrown toenail.
* 3.0 Paper wasp: Caustic & burning. Distinctly bitter aftertaste. Like spilling a beaker of Hydrochloric acid on a paper cut.
* 4.0 Pepsis wasp: Blinding, fierce, shockingly electric. A running hair drier has been dropped into your bubble bath (if you get stung by one you might as well lie down and scream).
* 4.0+ Bullet ant: Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail in your heel.

Oh, boy. I'm real familiar with what it feels like to be stung by a sweat bee and a fire ant. The latter, especially, is not a lot of fun. And these bugs are very low on this scale...

That's enough to get me to be careful when I'm in the vicinity of tarantula hawks. As luck would have it, just after I discovered the pain potential in my insectly neighbors (this was a few years ago), I was outside doing some tractor work for a friend down the road from us. As I was merrily put-putting along on my Kubota, a tarantula hawk swooped around my left side, bobbled around right in front of me, and ... landed on my right arm. I know enough about the behavior of wasps to know that this thing wasn't really trying to attack me — especially if I did nothing to threaten it. But it was a little ... challenging ... to not react in this situation. In the end, though, this was quite rewarding: I stopped using my right arm to steer, brought the tractor to a halt, and had about 30 seconds of right-in-my-face observation time on this bug. And I have to tell you, it was one of the most interesting and most beautiful insects I've ever been able to see so close up. Still, I was happy when it took off, and left me alone.

A couple of years later, we spotted another tarantula hawk with a tarantula, wandering all over the side of our house trying to find a place to hide it. The tarantula hawks don't eat tarantulas (they're nectar feeders), but the females will sting and paralyze a tarantula to provide a nice cozy home for their kids:

A female wasp finds a tarantula by smell. Generally, she scampers across the ground to locate a burrow. She will enter the burrow and expel the spider, then attack it. She may also encounter a male tarantula during his search for a mate. In an attack, the wasp uses her antennae to probe the spider, which may raise its front legs and bare its fangs. (A tarantula does not always counterattack.) She then attempts to sting the spider. She might seize the spider by a leg, flip it over on its back and sting it, or she may approach from the side to deliver a sting. Once stung, the tarantula becomes paralyzed within seconds. The condition will last for the remainder of its life. The wasp may drink the body fluids oozing from the spider’s wounds or from its mouth to replenish nutrients and water she used during the attack.

Motherhood is a lovely thing, isn't it?

A couple of strange little factoids about tarantula hawks:

Tarantula hawks are the state insect of New Mexico. What on earth were they thinking?

Tarantula hawks can become "flight-challenged" after eating fermented nectar. Drunk wasps with horribly painful stings — sounds like giving a loaded gun and car keys to a drunk, angry teenager...

Comments

After being nudged by one of my readers, I've turned comments back on — but they're moderated (by me). As some of you know, I used to have comments turned on, wide-open. The result was unacceptable to me: comment spam (lots of it!), unreasonably profanity, and uncalled-for personal attacks on me or others. Your comments certainly don't need to agree with my post — in fact, disagreement is much more interesting! You just need to post in a civilized form.

And remember, an adult (me) will be supervising. Your comments will not appear publicly until I approve them.

Condom Colonialism

George Bush has gotten very little credit in the MSM for his unprecedented USAIDS initiative. It is unprecedented in at least two ways: the sheer size of the financial commitment, and in the results it is producing. On the latter, it is particularly striking how effective the USAIDS efforts have been when compared against the vastly more expensive and longer ongoing U.N. efforts.

The U.N. has, predictably, objected strongly to the USAIDS initiative as unilateral and driven by a religious motive. The latter criticism derives from the fact that USAIDS is funding efforts to promote abstinence and faithfulness, particularly in Uganda, where the government has been very supportive. Oh, by the way — something you may not have read in the MSM — these efforts in Uganda have been stunningly effective in reducing the rate of AIDS in that country.

Mark Steyn tackles this precise issue in his new column about "condom colonialism". An excerpt:

But, after two decades, condom colonialism seems to have done nothing for southern Africa. The latest "conventional wisdom" among western do-gooders — that rapacious pharmaceutical companies should have their patents stolen in the interests of supplying cheap generic drugs to the continent — is also supported by Stephen Lewis and WHO. If condom worship is largely ineffectual, Big Pharma demonization has the potential to be utterly disastrous. Already, "pre-qualified" cheap AIDS drugs made in India have had to be "de-listed" by WHO, when they were subsequently revealed not to have met even WHO's minimal standards, by which time they were already widely circulated all around Africa. As things turned out, they weren't even cheaper--and the principal result seems likely to be not healthy Africans but Africans who develop strains of AIDS resistant to western drugs, while western pharmaceutical companies have less and less interest in developing drugs for those new strains if their patents are going to be stolen by the transnational establishment.

The Bush initiative, on the other hand, ensures African HIV sufferers will receive drugs that meet U.S. standards.

As they say, read the whole thing.

Related: It strikes me (a very non-religious guy) as kind of scary for the U.N. to take the position that promoting abstinence and faithfulness is wrong because it is (supposedly) based in religion. Scary on two counts: that the organization supposedly representing the world's people would discount the religions that so many of those people (though not me) believe in, and that the organization would dismiss the promotion of a behavior effective in reducing disease simply because the behavior corresponds with a moral standard whose parentage they believe (whether correctly or incorrectly) is religion. What the hell is the U.N. doing making judgments on such matters?

U.N. Accountability

Claudia Rosett has been investigating the U.N. Oil-for-Food scandal, and investiating the investigators (the Volcker Commission). Up on the Weekly Standard this week is her latest column on the matter. An excerpt:

If Volcker's September 7 "main report" is to be the final word on U.N. management of this fiasco, then the bottom line is this: Under a program involving thousands of U.N. employees, nine U.N. agencies, and an administrative budget totaling $1.4 billion, the United Nations abetted Saddam Hussein in one of the biggest heists in history--and no one, except for a couple of third-tier U.N. officials, is being punished for it. Annan, having taken "responsibility," is still at his post. His deputy, Louise Fréchette, having directly supervised the corrupt official heading Oil-for-Food, is now in charge of U.N. reform. And the former head of Oil-for-Food, Benon Sevan, accused by Volcker of taking at least $147,000 in bribes from Saddam, has been allowed to cash in his U.N. pension and leave the country.

She summarizes very nicely what has been frustrating to me: the complete lack of accountability at the U.N. Combine that with it's complete lack of effectiveness and relevance, and I can't help but join the (growing) group of people who are wondering why in the heck we have a U.N. at all — and most especially why do we have a U.N. that is (a) largely financed by the U.S. taxpayer, and (b) headquartered on American soil.

What's the point, exactly? Someone please let me know...

Barone's Patterns

Michael Barone has a typically excellent column up on RealClearPolitics. Any excerpt:

A world spinning out of control: That is what the old-line broadcast networks seem to be showing us. But I see other patterns. George W. Bush has consistently asserted that one reason for removing Saddam Hussein's regime in Iraq was to advance freedom and democracy in the Middle East. In spite of the improvised explosive devices, that seems to be happening. Lebanon's Cedar Revolution was as inspiring an example of people power as the fall of the Berlin Wall in 1989. Libya has dismantled its weapons of mass destruction. Egypt, by far the largest Arab nation, had its first contested election this month, and, as the Washington Post's David Ignatius writes from Cairo, "the power of the reform movement in the Arab world today ... is potent because it's coming from the Arab societies themselves and not just from democracy enthusiasts in Washington." Which is evidence that Bush was right: Muslims and Arabs, like people everywhere, want liberty and self-rule. Afghanistan has just voted, and Iraq is about to vote a second time this year. Violence continues, but the more important story is that democracy and freedom are advancing.

If you're not familiar with Michael "The Political Encyclopedia" Barone, I'd encourage you to rectify that. He's one of the most well-informed (in the sense of knowing history and political minutiae) voices out there...

Ants

Living in the chapparal means that you're living amongst animals of many kinds: birds, lizards, snakes, mammals, and insects. Most of these animals we cherish, and in fact we go out of our way to attract them to near our home so we can view them — we put out several kinds of seeds, suet, cracked corn, sugar water (for hummingbirds and orioles), and fresh water to lure all the animals.

But some of these animals are ... less desirable ... to have near our home. Mountain lions, though beautiful, are dangerous to our pets and possibly even to us. Rattlesnakes are less dangerous than their reputation, but still not exactly fun to share your yard with. Skunks, well, you know. Coyotes can be a problem, especially with pets. And there's an insect here that strikes fear into many people: the "tarantula hawk" (actually a wasp). But if you were to ask my wife to make a prioritized list of all the beasties she loves to hate, ants would be near the top, I'm sure.

Ants are marvelous little "machines" for finding food. And out here in the dry, near-desert of the chapparal, they've also honed their skills at finding water. Especially in the dry part of the year, they find some way to get into our home — where they're sure to find some sort of ant treat around. Next thing you know, there's a zillion ants crawling all over in a zig-zag track, piling up on whatever they found attractive. Might be a cup with some water in it, or the water left at the bottom of the dishwasher, or one of the pet's food bowls, or some leftovers that we forgot to send down the disposal. Whatever little morsel there is, those darned ants are going to find it. And for this survival skill they have earned Debi's eternal enmity.

But if you can get past the ... inconvenience ... of ants, there are some interesting things to know about them.

For instance, it's pretty obvious that ants, as a group, are very successful. But you may not be aware just how successful they are. If you measure success by the total weight of a group of animals, then scientists will tell you that ants are either #1 or #2 amongst all kinds of animals (if you include termites in with ants). From the proceedings of the National Academy of the Sciences:

Ants are arguably the greatest success story in the history of terrestrial metazoa. On average, ants monopolize 15-20% of the terrestrial animal biomass, and in tropical regions where ants are especially abundant, they monopolize 25% or more. But ants did not always run the world. They do not appear in the fossil record until the mid-Cretaceous, and for more than the first half of their history — a period spanning 60 to 80 million years — ants occupied a relatively modest position in the terrestrial biosphere. To understand the factors, both ecological and historical, that contributed to the rise of the ants, we require a clearer picture of the stepwise evolution of the major ant lineages. Now, Grimaldi and Agosti report in a recent issue of PNAS the remarkable discovery of a worker ant, preserved in amber for over 90 million years, that is clearly assignable to a modern ant subfamily that contains many familiar extant species, including carpenter ants. Combined with other paleontological and phylogenetic information, this unexpected fossil strongly indicates that the diversification of many ant subfamilies occurred earlier and more rapidly than previously suspected.

Ants represent the family Formicidae in the insect order Hymenoptera and, like the yellow jackets, hornets, and paper wasps to which they are closely related, ants are stinging wasps. All ants are eusocial, that is, they live in colonies in which a wingless neuter daughter caste cooperates to raise subsequent generations of their mother queen's offspring. Like all of its descendants, the ancestral ant was almost certainly eusocial, with colonies made up of small bands of hunter-gatherers living in simple temporary nests in the soil. From this modest beginning arose the current diversity of the family Formicidae, numbering over 9,500 described species and an estimated 3,000 to 9,000 additional species as yet unknown to science. Today ants occupy keystone positions in most terrestrial environments, serving as major conduits of energy and organic material. They are, for example, important turners of the soil, matching or exceeding the activity of earthworms in this role. They are among the leading predators of invertebrates in most ecosystems, and in the Neotropics they are the leading herbivores as well, with leaf-cutter ants taking more than 15% of the fresh vegetation (feeding it to a symbiotic fungus, which they in turn eat). Interactions with ants have shaped the evolution of diverse organisms to an astonishing degree. Ants participate in symbioses — some facultative, some obligate — with over 465 plant species in over 52 families, with thousands of arthropod species, and with as-yet-unknown numbers of fungi and microorganisms. Clearly, the study of most ecosystems must include the study of the resident ant species. Because of their complex colony-level behaviors, ants serve as model organisms for the highly visible disciplines of behavioral ecology and sociobiology, particularly in studies focused on the dynamics of kin selection, within-colony conflicts of interest, caste differentiation, and division of labor.

When you consider how many ants it would take to equal the mass of a single human, and then consider that there are something like 6 billion humans — it's a little difficult to even imagine the number of ants it would take to exceed the weight of all humans. But there really are that many ants, and more — depending on whose estimate you want to believe, the ants weigh somewhere between 2 and 8 times as much as humans!

Wikipedia has an excellent article (with good links) on the Earth's biomass, and the Mad Scientist Network has this article about the biomass of ants.

Of special interest to Debi are things that eat ants. Especially if the ant suffers a little in the process. As you might expect for anything that makes up a goodly percentage of the Earth's biomass, lots of animals of various kinds have decided that ants can be tasty. The preceding link goes to Dale Ward's website, which (amongst other things) has lots of good information about ants.

Lunar Librations

After my recent post on the Harvest Moon, a friend emailed me with this:

I'm somehow disappointed with your picture of the moon at apogee and perigee. The non-circular orbit also has the effect of producing lunar librations so we can see more than 50% of the moon. I can't help but think this is in sync with the apogee and perigee of the moon so the two images should look different (the two extremes) instead of being a 30% reduction of one another. But I'm just guessing...

The animation at right (shamelessly ripped from Astronomy Picture of the Day, but modified to slow it down) shows the lunar libration my friend speaks of. I, too, knew of the librations without really understanding the mechanism behind them. My friend's email nudged me into a little research.

My initial guess about lunar libration was that these two things caused it:

1: The tilt of the lunar orbit (5.2 degrees) with respect to the earth's rotation, coupled with the latitude (on the Earth) of the observer. This slightly "tilts" the view an observer has, to see slightly past the north or south pole.

2: The displacement of an observer viewing the moon at moonrise versus an observer at moonset. This would allow an observer to see slightly past the nominal east and west sides of the moon.

It turns out that both of the mechanisms I described above do contribute to libration (both latitudnal and longitudinal), but I completely missed two other mechanisms, the first of which causes the most libration:

1: The moon's rotational rate is constant, while its speed in its orbit about the Earth is variable. More on this below.

2: The moon's rotation is tiled about 1.5 degrees to the plane of its orbit. This adds another 1.5 degrees to the first effect I had guessed, for a total of 6.7 degrees.

For me the most interesting of these four mechanisms is the one that has the biggest effect, and that I had completely missed. It depends on a marvelously subtle interplay between the moon's constant rotational speed and variable orbital speed. As my friend guessed, the ellipical (non-circular) orbit of the moon is the cause of this — but the effect is the opposite of what he guessed: at apogee and perigee, there is no libration at all!

This unexpected outcome derives from the characteristics of an elliptical orbit. At perigee (the point of the moon's closest approach to the Earth) the moon is moving faster than at apogee (the point of the moon's farthest distance from Earth). The way I puzzled this out was to divide the moon's orbit into quarters, with one dividing line from perigee to apogee, and the other at 90 degrees to that. Starting at the perigee, let's call the quarter-orbits I, II, III, and IV. The moon is observably at dead center (with respect to longitudinal libration) at both perigee and apogee. To explain the longitudinal libration, let's follow the moon through the four quarters of its orbit:

Quarter I: The moon starts at perigee, where it is moving faster than at any other point in its orbit. During this quarter orbit, the moon will slow down some, but it's still moving faster than the average speed over the entire orbit. This means that the moon reachs the end of the first quarter of its orbit in slighly less than one quarter of the time it takes for an entire orbit — so the moon will have rotated slightly less than one quarter of a rotation. In fact, it turns out that the moon at this point has only rotated about 82 degrees — thus providing a view for an Earth-bound observer that is 8 degrees (90 - 82 = 8) of longitude shifted.

Quarter II: The moon is moving further from Earth, and is slowing down. At the end of this quarter, it has moved through exactly half of its orbit, and it has rotated through exactly half its rotation — so no longitudinal libration.

Quarter III: The moon is moving closer to Earth, and is speeding up. However, its speed during this quarter is lower than the average speed over the entire orbit. That means that the moon takes slightly more than one quarter of an orbital period to reach the end of this quarter orbit. Because of that, the moon has rotated slighly more than one quarter of a rotation — about 98 degrees instead of 90. That means that an Earth-bound observer has a view that is shifted 8 degrees (90 - 98 = -8) longitudinally, in the opposite direction as occurred in quarter I.

Quarter IV: The moon is moving closer to Earth, and is speeding up. At the end of this quarter, it has moved through its entire orbit, and it has rotated exactly once — so no longitudinal libration.

I'll bet that was more than most of you ever wanted to know about lunar libration! But if you're anything like as loony as I am, you can find more information about lunar libration here, here, here, especially here, and here.

Veggie Lunch

Our local stores and produce stands have had really nice asparagus and Brussel sprouts the past few weeks. Debi picked some of each up on her last shopping, and today we had an all-veggie lunch: just fresh asparagus and sprouts, with a little butter and salt.

Oh. My. God.

They were so good!

Up to now, the only thing I've ever had that tempted me into a homogenous diet was sushi. Fresh veggies of this quality are the second...

Sycuan Peak

Sometime last year I discovered that we had a nature reserve practically in our own back yard. It's called the "Sycuan Peak Ecological Reserve", and it's part of the state system of reserves, managed by the California Department of Fish & Game. Sycuan Peak itself is smack in the middle of this reserve, just southwest of Loveland reservoir. The southern edge of the reserve borders Lawson Valley Road, just three miles from our home.

Within a hundred feet or so of the 2.5 mile marker on Lawson Valley Road is an unmarked (though there used to be a sign) rugged four-wheel drive road up the small peak to the north. This is the "trail" to Sycuan Peak, actually an old and heavily eroded jeep trail. Much of the road is actually still drivable by four-wheel (though I don't believe you're actually supposed to drive on it), but toward the top it's pretty much impassable by vehicle. This morning Jim Barnick and I hiked up to the peak with our two dogs (Mo'i and Lea); this was the first time we'd ever done so.

The trail is just a mile long, but steep, with an 850 foot elevation gain in that short distance. The views all along the trail are spectacular, perhaps especially for someone living in that area. From the top we had the best view of Loveland Reservoir that I've ever had from the ground (first photo). The view to the north included a great view of Cajon Mountain (second photo). To the west we had a spectacular, nearly uninterrupted view of the Pacific coastline — only Miguel Peak punctures the horizon from Sycuan Peak, and by less than a degree. The skies were a bit hazy today, especially to the west; we'll do this again on a really clear winter day and I'll take a panorama.

Our dogs thoroughly enjoyed this hike. No surprise there! But one thing that was a little surprising: our agile little female (Lea) actually got a little tuckered out on the way up. She usually tries to pull us up the hill whenever we're walking with her; she's incurably eager to see what's around the next bend. This time, though, she started slowing down at around the 2/3 mark — enough so that I got concerned she might be overheating or something, and we stopped to rest. That was the cure — a few minutes standing still and she was good as new. At the top we gave both dogs a nice drink by pouring water into our cupped hand. Both of them had a little trouble figuring that out <smile>.

One interesting factoid about the Sycuan Peak Reserve: it is the primary remaining habitat for a very rare plant: Nolina interrata, commonly known as the "Dehesa Beargrass". From the U.S. Fish and Wildlife Service site:

A total of about 9,000 Nolina interrata plants are known (FWS 1998a, TNC 1998).

There are nine populations of Nolina interrata in San Diego County, all within a 15.6 square km (6 square mile) area in the Dehesa Valley, immediately east of El Cajon, California and from three small, somewhat disjunct populations in northern Baja California, Mexico. There are no records of extirpated populations (FWS 1998a, TNC 1998).

About two-thirds of all populations, and 90-100 percent of all major populations, are protected on reserve lands owned and managed by The Nature Conservancy (TNC) at McGinty Mountain and by the California Department of Fish and Game (CDFG) at Sycuan Peak. The protection afforded by the establishment of the Sycuan Ecological Preserve occurred subsequent to the proposal to list Nolina interrata. The remaining few occurrences are small and are on private lands (FWS 1998a).

Jim and I did not search for this plant during our hike; we'll save that for another day. Not being plant experts, I suspect we may have a little trouble positively identifying it even if we did manage to find it <smile>.

Nine thousand individuals sounds like an extremely small population, at risk all the more because they're located in just a few concentrated populations. The FWS web site mentions that Nolina interrata flowers profusely after a fire; parts of the Sycuan Peak Reserve (if I have got the borders correctly) burned in the Pines fire of 2001. We can hope for a bit of a comeback from that. Also in the FWS web site is mention that at least one of the isolated populations appears to be composed entirely of genetic clones of one plant; another risk factor. There's more information on this plant (including photos) here, here, and here.

The geocachers have discovered Sycuan Peak as well. Jim and I didn't try to find this particular one, but it's clear from the description that it's somewhere very close to the peak.

APOD

APOD brings us...

Staring across interstellar space, the alluring Cat's Eye nebula lies three thousand light-years from Earth. A classic planetary nebula, the Cat's Eye (NGC 6543) represents a final, brief yet glorious phase in the life of a sun-like star. This nebula's dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. But the formation of the beautiful, more complex inner structures is not well understood. Seen so clearly in this sharp Hubble Space Telescope image, the truly cosmic eye is over half a light-year across. Of course, gazing into the Cat's Eye, astronomers may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution ... in about 5 billion years.

We live in a time where technology has enabled us to do and enjoy things that our ancestors could hardly imagine. For example, my photography hobby makes it possible for me to capture marvelous images of nature, and the people and animals I love.

These images have become very important to me. For others, it may be video tapes, or audio recordings. Or email: I have a lot of personal history saved in emails. Or my web sites — I have even more history and "sweat equity" saved there.

This leads to a concern that's unique to our digital age. All of this "stuff" that we want to keep, and perhaps to pass along to the future: how do we save it in a form in which people can use it in the future?

Lest you think this is an arcane concern, think about what has already happened to 45 RPM records. Could you play one at your home? I certainly could not...

I am by no means the first to worry about this. The same problem applies to business records, research results, and government records; these issues have lots of people worried. The general topic has even acquired a catchy name: the "Digital Dark Age". Danny Hillis, a famous computer designer, makes this observation:

... Danny Hillis also put the problem in perspective at a conference on "Digital Continuity" held at the Getty Center in Los Angeles in February 1998. "Back when information was hard to copy" said Hillis, "people valued the copies and took care of them. Now, copies are so common as to be considered worthless, and very little attention is given to preserving them over the long term." He noted that thousands of years ago we recorded important matters on clay and stone that lasted thousands of years. Hundreds of years ago we used parchment that lasted hundreds of years.

As a result, Hillis suggests, we are now in a period that may be a maddening blank to future historians — a Dark Age — because nearly all of our art, science, news, and other records are being created and stored on media that we know can't outlast even our own lifetimes. We arrived at this situation partly because digitization otherwise offers so many profound benefits. We can now store, search, and cross-correlate literally everything. In fact, according to estimates by Bellcore's Michael Lesk, who calculated the total amount of data there is in the whole world, storage has now surpassed data, probably permanently. There is more room to store stuff than there is stuff to store. We need never again throw anything away. That particular role of archivists and curators has become obsolete.

All of this rings true, for example, for my personal photography work. With my digital camera, it costs nothing to take a picture — so of course I take many more than I used to. I now have over 100,000 of my personal photographs saved; each photo that I've spent time editing and processing is saved multiple times. They all fit on one small computer in my office. I can access any of them in mere seconds, and they're all organized very conveniently. Imagine if I were to save these on slide negatives (which would preserve them without concern for technological changes): they would occupy something like 30 cubic feet, and much more if organized in boxes per topic (like I have my electronic files organized). That's just not going to happen; I'm not willing to give up the convenience and small size of the electronic storage format.

So what can we do to preserve the electronic stuff we care about?

In the world of business and government, so far as I can tell there are two general kinds of efforts underway. One kind tries to impose a (hopefully) durable standard on the world; the other gives up on a standard and instead tries to find a way to convert the wildly variable world to one form that will be durable only within the archival system. Both of these are incredibly difficult to pull off.

The first approach suffers from a problem that seems completely intractable to me, because technology is evolving so quickly (and at an ever-accelerating rate, to boot). The problem is that any standard you might choose today is likely to be rendered completely obsolete by new technology developments. Some of these will be surprising; others are completely predictable. For an example of the latter, consider the way we represent images digitally today. Generally speaking (and I'm over-simplifying), images are represented as rectangular arrays (or grids) of dots (called pixels). Each dot has three values associated with it: one each for the intensity of red, green, and blue light at that dot's position. By mixing these three colors appropriately one can generate any color, or at least we can fool our eyes into seeing that color. If someone were designing a durable standard for image storage today, they'd be quite likely to base it on this kind of representation. The problem is that it's quite likely (in my opinion) that this will change as our sensors get more and more sophisticated. I wouldn't be a bit surprised to discover, at some point in the future, that we were using cameras that essentially took a spectragraph at every pixel. This would be much more information at each pixel than we get today — and the red/green/blue method of storing an image would be completely unable to deal with it. So much for our durable standard...

The second approach has a much different kind of difficulty: it is an almost unimaginably large and complex problem to handle in a comprehensive way. I can't imagine any organization short of a government or a monster company (such as Google or Microsoft) pulling this off. Actually, it seems like a natural fit for Google, as once you had all that information stored, of course you'll have to provide a way to get at it. This, I think, is the approach that is most likely to succeed. I suspect it will be made available as a web-based service to consumers, which will be how we finally solve the problem of how to store our stuff.

But what do we do with our stuff between now and that happy day when Google announces "Google Stuff", or whatever they call the service I postulate? The only general rule I can think of is this: be careful not to store anything you care about in some completely proprietary form. Or, at the very least, if you choose some proprietary storage means, make sure you can "export" your stuff from that proprietary system to something more standard.

Here's a some other interesting articles on the subject, here, here, and here.

Sunrise

We woke early enough to see the sun rise this morning, and at about 6:25 AM local time it was just about as pretty as a sunrise can get. We had a light layer of cloud in the eastern regions where the sun rises this time of year, but clear everywhere else — so we had a gorgeous display of red and orange clouds contrasted with the incomparable "California blue" sky. It was changing so quickly that I didn't want to run in to get my camera (so no picture, sorry). In fact the whole display was over in just a couple of minutes...

Energy Dreamin'

Donald Sensing over at One Hand Clapping posted today about how we're really stuck with internal combustion engines, as the alternatives under development today (hybrids and hydrogen-fueled cars) don't really solve the problems. An excerpt:

But what about hydrogen cars? They would burn hydrogen and oxygen and emit water. How cool would that be, eh? But writer Patrick Bedard says that if by a trick of science autos had been invented using hydrogen-oxygen motors, so that everyone was driving them now,

... President’s FreedomCAR initiative would be anteing up its $1.8 billion to invent the gasoline engine. Freeing us from hydrogen would be “the moral equivalent of war,” to use the words of a long-past energy-crisis president. Gasoline would be the miracle fuel. It would save money by the Fort Knoxful. It would save energy by the Saudi Arabiaful.

The reason is that the amount of energy required to produce a kilogram of hydrogen is simply enormous, many multiples more than the energy recovered by using the hydrogen as a fuel. Where would all that energy come from?

Virtually all the hydrogen produced today, about 50 million tons worldwide, comes from natural gas. The process, called “steam reforming,” is only about 30 percent efficient, much less, he [Donald Anthrop, Ph.D., professor emeritus of environmental studies at San Jose State University] says, “than if the natural gas were simply burned” in the generating plant.

Producing enough hydrogen to replace gasoline by reforming natural gas would increase our [natural] gas consumption by 66 percent over 2002’s usage. And don’t forget the carbon emissions.

Mr. Sensing is talking about one of my pet peeves with the alternative energy promoters: in general, they seem to have neglected the most fundamental problems with whatever energy source they're promoting — and I can't think of a better example of this than the promoters of hydrogen vehicles. The hydrogen-powered cars are a great example, as Mr. Sensing points out. Where's all that hydrogen going to come from? While it's true that today most hydrogen is produced from natural gas, what most promoters of a hydrogen-based energy economy assume is that hydrogen will be produced by "cracking" water into its constituents (hydrogen and oxygen). Cracking water requires as much energy as was produced when the hydrogen originally "burned" to produce the water in the first place, plus whatever inefficiencies are inherent in the process. Because cracking water is best done through electrolysis, this means lots of new generating capacity — 241 gigawatts just to run the cars in the U.S. — is needed. From Leon Walters at the Argonne National Laboratory:

"Renewable energy technologies - wind, solar and geothermal - can make an important contribution," he said. "These technologies tend to be too intermittent to provide reliable base-load electricity, but they can generate hydrogen and store it when the wind is blowing or the sun is out. On the other hand, they are too diffuse to generate 241 gigawatts of new capacity. You'd need 640,000 windmills, for example, which would occupy a total land area of 71,000 square miles - nearly the size of Ohio and Indiana combined.

Mr. Walters goes on to say that (basically) the only technology available to us to produce this kind of power without polluting the air is ... nuclear. Reactors could be built to produce that extra 241 gigawatts of electricity, or could be used in other processes (such as thermochemical) to produce the hydrogen needed.

Can't you just hear the environmentalist wackos reacting to the idea of (say) another 50 or 100 nuclear power plants scattered around the country? And while the reactors may not pollute the air, what the heck would we do with all the nuclear waste they generate? We can't even get rid of the waste from the few reactors we have today.

Sigh.

Further information about hydrogen cars can be found here, here, and here.

Hybrid cars provide another interesting example of this neglect of fundamentals. For people who drive mostly in the city, with little highway driving, it is possible to make a hybrid vehicle that will get much better gas mileage, and will save enough money on fuel to pay for the extra cost of the vehicle over its lifetime. But that's the exceptional case, unfortunately.

Drivers who spend a lot of time on the highway will see no gain in their fuel efficiency for those miles. In fact, it may actually be worse — as all the extra weight of the batteries and extra mechanical components has to be lugged around. These drivers will not win on either fuel efficiency or overall cost.

As hybrids enter the market, manufacturers are learning what consumers like and dislike about them. One early lesson: consumers want power and responsiveness. The result is that more recent hybrids have compromised fuel efficiency to deliver what consumers want — and actual fuel efficiencies achieved (as opposed to the highly unrealistic EPA tests) are often little better than can be had for much less money with conventionally powered cars. Once again, a double "no win".

So what's the lesson in all this? Just this: be skeptical about the "save the earth" claims of the alternative energy promoters. Nobody has yet come up with an alternative energy source (to hydrocarbon) that is (a) practicable to implement, (b) delivers increased efficiency and reduced pollution, and (c) is usable for all those things we use energy for, most especially vehicular systems. Energy generation and distribution is a very challenging problem that hydrocarbon fuels happen to address very, very well. It's going to be quite a while before something better can displace it...

Perspective

Over at "The Adventures of Chester," there's a longish but thought-provoking post about how the Iraq war is being reported in the MSM. The heart of the post is a comparison between some MSM reporting (from TIME) and some "alternative reporting" (from Col H.R. McMaster), Commander of the 3rd Armored Cavalry Regiment, with both reporting on the same subject. An example:

TIME:

Waiting for the Americans were hundreds of hardened local fighters, small bands of foreign zealots and in the notorious Sarai quarter of the city, a labyrinth of medieval alleyways laced with booby traps and roadside bombs.

Col McMaster:

These were very complex defenses in neighborhoods outside of the Sarai neighborhood, which was the center of the enemy's safe haven here. They had their command and control in a safe house in the center that was very heavily defended. Outside of that, they had defensive positions with RPG and machine gun positions. Surrounding those positions, they had homes that were rigged to be demolished by munitions as U.S. and Iraqi soldiers entered them, and then, outside of those, they had Improvised Explosive Devices, roadside bombs, implanted, buried into the roads.

But our forces aggressively pursued the enemy in these areas. They were able to defeat these IEDs based on the human intelligence we developed. We exploded many of them with attack helicopter fire or detonated them with our engineers. We penetrated that defense. Our tanks led with our Iraqi infantry in support. We absorbed any energy from their rocket-propelled grenades and machine guns, continued the assault into these safe havens and destroyed their leadership throughout the city. The word then went out that — to the enemy that put other elements on notice: look, we're being slaughtered here; we need to avoid these very effective combined forces of Iraqi and U.S. forces. But we continued to relentlessly pursue them as we moved to isolate the Sarai district. In Sarai, the most dense urban terrain you can imagine, there was a very complex defense prepared there, with, again, these roadside bombs, buildings rigged for demolition, machine gun positions, sniper positions, and mortars integrated into this. But with our intelligence, our precision fires capability, we were able to severely disrupt that defense and really collapse it all around the enemy.

Early in this same post, Chester points out this Flash presentation giving a high level perspective of recent operations in Iraq. It is excellent; take the time to go look at it.

Iraqi Permanent Fund

Michael Barone (who's always worth reading) has an interesting idea that I haven't heard elsewhere:

An Iraqi Permanent Fund would take all or some substantial part of Iraq's oil royalties, invest them, and pay annual dividends to every citizen. I have urged this as long ago as April 2003, and the New America Foundation's Steven Clemons urged the same thing in a piece that appeared at just about the same time in the New York Times.

It seems to me that an Iraqi Permanent Fund would have several good effects.

It would reduce the flow of oil money to the state. In most oil-rich states, that money has become a source of corruption and an incentive for greedy men to seize dictatorial control of the state.

Read the whole thing. And stop in to his blog from time-to-time; there's always thoughtful commentary up there...

Porkbusters

Now here's a blogospheric effort I think we could all support:

How are we going to mobilize the blogosphere in support of cuts in wasteful spending to support Katrina relief? Here's the plan.

Identify some wasteful spending in your state or (even better) Congressional District. Put up a blog post on it. Go to N.Z. Bear's new PorkBusters page and list the pork, and add a link to your post.

Then call your Senators and Representative and ask them if they're willing to support having that program cut or -- failing that -- what else they're willing to cut in order to fund Katrina relief. (Be polite, identify yourself as a local blogger and let them know you're going to post the response on your blog). Post the results. Then go back to NZ Bear's page and post a link to your followup blog post.

The result should be a pretty good resource of dubious spending, and Congressional comments thereon, for review by blogs, members of the media, etc. And maybe even members of Congress looking for wasteful spending . . . .

At the time of this post, the only politician who has committed to some pork-busting is Nancy Pelosi! Tom Delay, how could you sleep last night? How can you let the wicked witch of the west take the lead on this issue, which should be near and dear to any Republican's heart?

Accident Report

The Bricklayers Accident Report

This is a bricklayer's accident report that was printed in the newsletter of the English equivalent of the Workers' Compensation Board.

Dear Sir;

I am writing in response to your request for additional information in Block #3 of the accident reporting form. I put "Poor Planning" as the cause of my accident. You asked for a fuller explanation and I trust the following details will be sufficient.

I am a bricklayer by trade. On the day of the accident, I was working alone on the roof of a new six-story building. When I completed my work, I found I had some bricks left over which when weighed later were found to weigh 240 pounds. Rather than carry the bricks down by hand, I decided to lower them in a barrel by using a pulley which was attached to the side of the building at the sixth floor.

Securing the rope at ground level, I went up to the roof, swung the barrel out and loaded the bricks into it. Then I went down and untied the rope, holding it tightly to insure a slow descent of the 240 pounds of bricks. You will note on the accident reporting form that my weight is 135 pounds. Due to my surprise at being jerked off the ground so suddenly, I lost my presence of mind and forgot to let go of the rope. Needless to say, I proceeded at a rapid rate up the side of the building.

In the vicinity of the third floor, I met the barrel which was now proceeding downward at an equally impressive speed. This explains the fractured skull, minor abrasions and the broken collarbone, as listed in Section 3, accident reporting form.

Slowed only slightly, I continued my rapid ascent, not stopping until the fingers of my right hand were two knuckles deep into the pulley which I mentioned in Paragraph 2 of this correspondence. Fortunately by this time I had regained my presence of mind and was able to hold tightly to the rope, in spite of the excruciating pain I was now beginning to experience.

At approximately the same time, however, the barrel of bricks hit the ground-and the bottom fell out of the barrel. Now devoid of the weight of the bricks, the barrel weighed approximately 50 pounds. I refer you again to my weight. As you might imagine, I began a rapid descent down the side of the building. In the vicinity of the third floor, I met the barrel coming up. This accounts for the two fractured ankles, broken tooth and severe lacerations of my legs and lower body.

Here my luck began to change slightly. The encounter with the barrel seemed to slow me enough to lessen my injuries when I fell into the pile of bricks and fortunately only three vertebrae were cracked. I am sorry to report, however, as I lay there on the pile of bricks, in pain, unable to move and watching the empty barrel six stories above me, I again lost my composure and presence of mind and let go of the rope. And I lay there watching the empty barrel begin its journey back onto me.

Note from the editor: this is an update of an oldie-but-goodie urban legend. See Snopes for details on the original.

My New Car

I just got my new BMW 750Li, and returned to the dealer the next day, complaining that I couldn't figure out how the radio worked. The salesman explained that the radio was voice activated. Watch this! he said.."Nelson!" The radio replied, "Ricky or Willie?" "Willie!" he continued....and On The Road Again came from the speakers.

I drove away happy, and for the next few days, every time I'd say, "Beethoven!" I'd get beautiful classical music, and if I said, "Beatles!" I'd get one of their awesome songs.

One day, a couple ran a red light and nearly creamed my new car, but I swerved in time to avoid them. "ASS-HOLES!" I yelled.....

The French National Anthem began to play, sung by Jane Fonda and Michael Moore, backed up by John Kerry on guitar, Al Gore on drums and Bill Clinton on sax....

I LOVE THIS CAR!!!!!!
