## Daytime Moon and jet

April 17, 2014

Passenger jet and Moon. Photo by Rodger Schmitt, from Lake Powell, Utah.

Handheld Nikon.  Nikon stabilizing lens.  Good hands, I’d say.

Third to last time I was out near Lake Powell, I was with Rodger (and about a dozen others) organizing hearings of the President’s Commission on Americans Outdoors.  We flew into Page, Arizona, on an Otter II coming up from Phoenix flying low, looking for elk, and legally buzzing Rainbow Bridge (impressive from the air, too).

We had a luncheon meeting at Wahweap Marina, as I recall; no time for boating.

Then we were off to the South Rim of the Grand Canyon.  There we inspected pine trees 30 feet tall, growing between the ties of the then-abandoned rail lines.  (And did a lot of other stuff.)

Today trains carry tourists to the South Rim on those tracks, the trees gone.  Progress, really.

Rodger carries on in the knowledge that use of the outdoors, especially these public lands, heals souls, and sometimes gives you great photos.

Rodger said I could borrow the photo.  Thanks!

## Cross seas: Nature, or design?

April 16, 2014

Here’s just exactly the sort of thing that happens in nature that drives creationists nuts.  How could this happen without God personally working to confuse and/or delight the photographer?  Not to mention the physicist and mathematician.

Photo from the Twitter feed of Science Porn: “Go home waves you’re drunk. This is called cross sea btw pic.twitter.com/5Cv1UUo8QX”

Where? Somewhere in France, one might gather from the flag on the structure (lighthouse?).

Turns out to be a Wikipedia photo, with this intriguing caption:

Crossing swells, consisting of near-cnoidal wave trains. Photo taken from Phares des Baleines (Whale Lighthouse) at the western point of Île de Ré (Isle of Rhé), France, in the Atlantic Ocean. The interaction of such near-solitons in shallow water may be modeled through the Kadomtsev–Petviashvili equation.

Oh, you remember that one, don’t you?  The Kadomtsev–Petviashvili equation?

At least we confirmed it was taken in France.

They do everything differently in France, don’t they?

Update:Got an e-mail suggestion that I include the equation itself.  You may certainly click to Wikipedia to find it; here’s what it says over there:

In mathematics and physics, the Kadomtsev–Petviashvili equation – or KP equation, named after Boris Borisovich Kadomtsev and Vladimir Iosifovich Petviashvili – is a partial differential equation to describe nonlinearwave motion. The KP equation is usually written as:

$\displaystyle \partial_x(\partial_t u+u \partial_x u+\epsilon^2\partial_{xxx}u)+\lambda\partial_{yy}u=0$

where $\lambda=\pm 1$. The above form shows that the KP equation is a generalization to two spatial dimensions, x and y, of the one-dimensional Korteweg–de Vries (KdV) equation. To be physically meaningful, the wave propagation direction has to be not-too-far from the x direction, i.e. with only slow variations of solutions in the y direction.

Like the KdV equation, the KP equation is completely integrable. It can also be solved using the inverse scattering transform much like the nonlinear Schrödinger equation.

Certainly the longest equation ever published at Millard Fillmore’s Bathtub.

## Sky and stars peeking into Antelope Canyon

April 11, 2014

Upper and Lower Antelope Canyon, near Page Arizona, get more visitors annually than just about any other canyon except the Grand Canyon.  They cover only a few miles.

You’re not familiar with Antelope Canyon?  You’ve seen the photos, even if you don’t know the name of the place — it’s a slot canyon, carved as with a wandering knife into the sandstone at the top of the cliffs leading to the Colorado River.

Over at EarthSky, I found a view you haven’t seen before.

Antelope Canyon at night by Sergio Garcia Rill. Stunning contrast of rock painted by light, and stars. From EarthSky.com. Visit Sergio’s website and read more about this adventure.

Details from EarthSky.com:

Sergio Garcia Rill captured this beautiful image from within Upper Antelope Canyon in Arizona, which is the most visited slot canyon in the United States. A slot canyon is significantly deeper than it is wide. It’s formed by water rushing through rock. Sergio wrote:

During my recent trip to Arizona, I stopped by Page to get a chance at touring the now famous canyons (Upper and Lower Antelope) and I also had a chance to visit Upper Antelope at night.

I couldn’t really get too many shots with the sky (since the openings were very narrow and limited) but I liked this one in particular since I got a chance to set it up and do the light painting myself a couple of chambers behind from where my guide and another participant were working on another shot.

Thank you, Sergio.

Visit Sergio Garcia Rill’s Facebook page.

Readers here may remember Page was the final destination of my late oldest brother, Jerry.  To his credit, he urged me to make a special trip to see Antelope Canyon, because most of the times I visited, it was closed, or impassable.  Alas, I have not yet been to the place.

This is one of the gems of the Diné, the Navajo Nation, and another good reason to get familiar with redrock country.

## Some things never change: “We Want Beer,” in 1932 photo

April 8, 2014

1932?  Heck, that’s every Friday in some offices I’ve worked in — and schools.

## Dallas with rain clouds, March 27, 2014

March 29, 2014

Photo from the Dallas Karting Complex. Dallas, evening of March 27, 2014.  Photographer unidentified. David Worthington.

Funny thing is, this photo probably didn’t require much processing to look like this.  Advances in lighting, especially LEDs and color, mean that Dallas’s skyline can look much like this any night.

Nota bene: Mr. Higginbotham discovered the photographer to be David Worthington, who is selling prints.  I recommend Dallasites contact him to get one. (Anyone else, too; it’s a great shot.)

## Milky Way in perspective, Northern to the Southern Cross

March 29, 2014

Found on Twitter, via @SciencePorn – One of the most beautiful pictures I’ve ever seen. Star photography by Nicholas Buer pic.twitter.com/RlwvSQNBAy. Much larger view here.

Nicholas Buer works hard to get these shots — a bit of a master, no?

This one was the Astronomy Picture of the Day (APOD) for January 27, 2014 (click that link for a much larger and more glorious view).  Much more detail there, revealing that this is much more of the Milky Way than you’d usually see.

From the Northern to the Southern Cross
Image Credit & Copyright: Nicholas Buer Explanation: There is a road that connects the Northern to the Southern Cross but you have to be at the right place and time to see it. The road, as pictured above, is actually the central band of our Milky Way Galaxy; the right place, in this case, is dark Laguna Cejar in Salar de Atacama of Northern Chile; and the right time was in early October, just after sunset. Many sky wonders were captured then, including the bright Moon, inside the Milky Way arch; Venus, just above the Moon; Saturn and Mercury, just below the Moon; the Large and Small Magellanic Clouds satellite galaxies, on the far left; red airglow near the horizon on the image left; and the lights of small towns at several locations across the horizon. One might guess that composing this 30-image panorama would have been a serene experience, but for that one would have required earplugs to ignore the continued brays of wild donkeys.

## Snow falling on yucca on White Sands

March 18, 2014

Another great shot from America’s public lands:

Department of Interior Great American Outdoors Tumblr caption: One of the world’a great natural wonders – the glistening white sands @WhiteSands_NPS. #NewMexico pic.twitter.com/dbzPpIfSRW

One of the problems of touring places like White Sands National Monument is that most tourists arrive mid-day; most spectacular views are probably close to sunrise or sunset, when the sky adds colors other than “bright” to the scene.

### Like No Place Else on Earth

Rising from the heart of the Tularosa Basin is one of the world’s great natural wonders – the glistening white sands of New Mexico. Great wave-like dunes of gypsum sand have engulfed 275 square miles of desert, creating the world’s largest gypsum dunefield. White Sands National Monument preserves a major portion of this unique dunefield, along with the plants and animals that live here.

Yes, the same White Sands where the Trinity Project first triggered an atomic weapon, in 1945 — but the blast site is actually about 100 miles north of the National Monument on the military’s White Sands Missile Range. Historical reasons to visit, as well as nature and beauty reasons.

I assume that’s some sort of yucca in the photo; can you tell more specifically?

## Sunrise on the Shenandoah Mountains

March 11, 2014

This is a hopeful picture.

US Dept of Interior Tweet: Beautiful #sunrise over @ShenandoahNPS last weekend. #Virginia #travel #nature pic.twitter.com/T2sEgczGsz

Probably taken along the Blue Ridge Parkway.  At the bottom of the photo, note the stone wall, probably built by the Civilian Conservation Corps during the Franklin Roosevelt administration, and still contributing to America’s beauty and economy 80 years later.

I can imagine driving along, catching a beautiful sunrise, but not being at a point to stop to photograph it.  Driving farther along, the photographer found a safe place to stop, but the sunrise itself was gone by 15 minutes.  With the aid of a young tree, however, the photographer can recapture that moment of the Sun’s peeking over the horizon, without special effects.  Nice thought for the shot.

## It’s a desert out there: Salmon Research at Iliamna Lake, Alaska 2013 – Jason Ching film

March 6, 2014

Sitting in a hot trailer out on the northern New Mexico desert, Arizona State’s great soil scientist Tom Brown tipped back his cowboy hat, and asked me if I had been lonely over the previous week.  Classes at BYU started up in August, and our other field workers on the project, with the University of Utah Engineering Experiment Station, for EPA and New Mexico Public Service, had gone back to class.  My classes at the University of Utah didn’t start for a few more weeks — so I was holding down the fort by myself.

Dr. Brown’s expertise in reading air pollution damage on desert plants propelled a good part of the work.  He showed me how to tell the difference between sulfur dioxide damage and nitrogen oxide damage on grasses and other plants, and how to tell  when it was insects.  He had some great stories.  As a Mormon, he was also full of advice on life.

Between Farmington where our hotel was, and Teec Nos Pos where our most distant (non-wet) sampling site was, radio reception was lousy most of the time.  The Navajo-language AM station in Farmington played some of the best music, and sometimes it could be caught as far west as Shiprock .  Most of the time, driving across Navajoland, I had nothing but my thoughts to accompany me.  Well, thoughts and the all-too-frequent Navajo funeral processions, 50 pickups long on a two-lane highway.

“No, not lonely.  There’s a lot of work, I’ve got good books, and sleep is good,” I told him.

“Enjoy it,” Brown said.  “The best time for any researcher is out in the field.  And when you’re young, and you haven’t seen it all, it’s better.”

Brown spent a couple of days.  Within a couple of weeks I turned everything over to other Ph.Ds to shut down the wet sampling for the winter, and caught a ride back to Provo (closer to where I lived) in a Cessna with a pilot who loved to fly low enough to see the canyons along the way.  Get a map and think of the possibilities, with a landing in Moab; if you don’t drool at the thought of such a trip in the air but not too high, if your heart doesn’t actually beat faster thinking of such a trip, go see your physician for treatment.

By that time I was out of film, alas.

My few summers out in the desert chasing air pollution stay fixed in the surface of my memory.  Indian rice grass still excites me in the afternoon sun (Oryzopsis hymenoides) — one of the more beautiful of grasses, one of the more beautiful and soil-holding desert plants.  When hear the word “volcano,” I think of the Shiprock.  When I read of air pollution damage, I think of all the pinon, aspen, cottonwoods, firs and other trees we gassed; when I see aspen in its full autumn glory, I remember those dozen  or so leaves we caused to turn with SO2 (slight damage turns the leaves colors; greater damage makes them necrotic, a bit of a mirror of autumn).

All of that came back as I watched Jason Ching’s film, “Salmon Research at Iliamna Lake, Alaska 2013,” a simple six-minute compilation of shots taken with modern electronic cameras, including the hardy little GoPros, and with assistance from a DJI Phantom Quadcopter drone.  Wow, what we could have captured with that equipment!

Ching’s description of the film:

This video showcases the scenery of Iliamna Lake and shows some of the 2013 research of the Alaska Salmon Program’s Iliamna Lake research station, one of four main facilities in Southwest Alaska . Established in the 1940′s, the Program’s research has been focused on ecology and fisheries management relating primarily to salmon and the environment in Bristol Bay, Alaska.

I am very grateful to be a part of such a long standing, and prominent program that allows me to work in the field in such an incredible setting with fantastic folks. This is the second video I created, the first one in 2012, to merely show family and friends back at home what I’ve been up to during the summer. This video was often shot between, or during field sampling events so a special thanks goes out to all those who supported me by continuing to work while I fiddled with camera gear.

Do you really want to get kids more interested in science?  Show them this stuff.  Scientists get the front seats on cool stuff — and they often get paid to do it, though they won’t get rich.

Researching life, and rocks, geography and landscape, and water resources, one may be alone in a desert, or a desert of human communication.  Then one discovers just how beautiful the desert  is, all the time.

## North Korea: A hole in the fabric of the 21st century

February 25, 2014

Here’s a photograph of one of the greatest, and longest-running tragedies of our time.

No, that’s not a stretch of water in the red circle.  That’s North Korea, at night, blacked out by a lack of electrical lights.

Tweetpic from the Washington Post: North Korea looks like a sea of misery in this photo from space http://wapo.st/1c1B84q via @KnowMoreWP pic.twitter.com/nB3g8fa63Q

It’s a photo from the International Space Station taken in January.

The KnowMore blog from the Post describes the tragedy, and points to even more disturbing stories:

North Korea appears as nothing more than a shadow in the above photograph, taken at night aboard the International Space Station last month. South Korea’s eastern coastline is indistinguishable from the demilitarized zone along the border with the North, as though the Sea of Japan flowed into the Yellow Sea and Pyongyang were an island in a strait separating South Korea from China.

North Korea’s interior is nearly invisible from orbit at night, just as what happens inside the country on a day-to-day basis is largely invisible to the outside world. U.N. investigators managed to shine a little light into North Korea’s darkest corners last month.  [Click here to get to the U.N. report]

I’ve used similar photos in class.  It’s a powerful exercise.  North Korea is as dark as undeveloped and largely unpopulated areas of the Congo River Basin, the Australian Outback, the Arabian Peninsula’s “Empty Quarter,” and almost as dark as Antarctica.

No doubt stargazing is good in some of those dark spots in North Korea.  This is one case where the absence of light pollution does NOT indicate good planning, but instead an amazing paucity of rational development.

## Photography as an instrument of history: Ukraine’s Independence Square

February 21, 2014

Tweet from the Wall Street Journal shows, in very dramatic form, how photographs can be used to record history and current events, telling a story that words just cannot.

WSJ Wall Street Journal – #Ukraine’s Independence Square: then and now http://on.wsj.com/1d9q7IL pic.twitter.com/vzqPKj79Cb

In Ukraine, there’s an enormous difference between 2009 and 2014.  In five years, Kiev is a different city.

Do we attribute the differences to corrupt government, to the assault on democratic institutions, or to the movement to end the corruption and boost democracy?

It’s more impressive that I can show in a link here; at the WSJ site, the two photos are interactive — you can grab the middle line with your mouse and move it to see the damage in 2014.  Check it out.

Are there similar photographic comparisons for Syria, Egypt, Yemen, Venezuela, Brazil, China, Britain, the United States?  If you know of some, or if you have created some, will you share?

## When the Moon hits your eye, in Arches NP

February 12, 2014

Photo by Lynn Sessions; “THE EYE OF THE #MOON: North Window arch at Arches National Park in #Utah. #NatGeo pic.twitter.com/XwHfdWK5Ft

It’s just a click of the shutter?  Ha!

I’m assuming not a lot of post-photo processing on this. Lynn Sessions had to figure out when the Moon would be in the North Window Arch, calculate exposure, and shoot off enough of them to get a decent shot before the Moon moved.  I suspect the rocks were “painted” with a flashlight during the exposure.

(Haven’t yet found the technical details of the shot. But I did find this about the photographer:
I’m a frustrated amateur photographer who is trying to visit every corner in Utah as well as hike/photograph every canyon in southern Utah. More at http://www.DreamBreeze.com )

Patience, planning, creativity — then just push the button.

## Reflections in a window on the wild

January 29, 2014

From the U.S. Department of Interior: Really cool reflection photo from America’s largest national park: @WrangellStENPS in #Alaska. pic.twitter.com/WHUYkgJNTH

Wrangell-St. Elias is our largest National Park? At 20,587 square miles, it’s about 80% as large as West Virginia, and larger than nine other states.

Wrangell–St. Elias National Park and Preserve is a United States national park and national preserve managed by the National Park Service in south central Alaska. The park and preserve was established in 1980 by the Alaska National Interest Lands Conservation Act.[3] This protected area is included in an International Biosphere Reserve and is part of the Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek UNESCO World Heritage Site. The park and preserve form the largest area managed by the National Park Service in the United States by area with a total of 13,175,799 acres (20,587.19 sq mi; 53,320.57 km2). The park includes a large portion of the Saint Elias Mountains, which include most of the highest peaks in the United States and Canada, yet are within 10 miles (16 km) of tidewater, one of the highest reliefs in the world. Wrangell-St. Elias borders on Canada’s Kluane National Park and Reserve to the east and approaches the U.S. Glacier Bay National Park to the south. The chief distinction between park and preserve lands is that sport hunting is prohibited in the park and permitted in the preserve. In addition, 9,078,675 acres (3,674,009 ha) of the park are designated as the largest single wilderness in the United States.

Wrangell-St. Elias National Monument was initially designated on December 1, 1978 by President Jimmy Carter using the Antiquities Act, pending final legislation to resolve the allotment of public lands in Alaska. Establishment as a national park and preserve followed the passage of the Alaska National Interest Lands Conservation Act in 1980. The park, which is bigger than the nation of Switzerland, has long, extremely cold winters and a short summer season. It supports a variety of large mammals in an environment defined by relative land elevation. Plate tectonics are responsible for the uplift of the mountain ranges that cross the park. The park’s extreme high point is Mount St. Elias at 18,008 feet (5,489 m), the second tallest mountain in both the United States and Canada. The park has been shaped by the competing forces of volcanism and glaciation. Mount Wrangell is an active volcano, one of several volcanoes in the western Wrangell Mountains. In the St. Elias Range Mount Churchill has erupted explosively within the past 2000 years. The park’s glacial features include Malaspina Glacier, the largest piedmont glacier in North America, Hubbard Glacier, the longest tidewater glacier in Alaska, and Nabesna Glacier, the world’s longest valley glacier. The Bagley Icefield covers much of the park’s interior, which includes 60% of the permanently ice-covered terrain in Alaska. At the center of the park, the boomtown of Kennecott exploited one of the world’s richest deposits of copper from 1903 to 1938, exposed by and in part incorporated into Kennicott Glacier. The mine buildings and mills, now abandoned, compose a National Historic Landmark district.

## Beautiful Antarctica: Photos, or painting?

January 27, 2014

This one is cropping up all over the internet.

But just try to get a commitment as to its origins.  Photographic, or artist’s image?

I wagered the latter. Note general lack of thick clouds, angle of sunlight, etc.

Beautiful Antarctica from space. Photographic image, or artist’s rendering? Who deserves credit for the image?

Then, at Twisted Sifter (shout out to Annette Breedlove; and everyone outside my family will be mystified by that reference) I found this, the full image from NASA.  Notice how some selective editing, changing the perspective, makes the image above more fascinating — while stripping out the identifying credits:

Image via Twisted Sifter; NASA image of Antarctica, available at Flickr Commons

Well, that’s a different thing, then.

Twisted Sifter’s explanation of details, excerpt:

Seen above is a view of the Earth on September 21, 2005 with the full Antarctic region visible. The composite image shows the sea ice on September 21, 2005, the date at which the sea ice was at its minimum extent in the northern hemisphere. The colour of the sea ice is derived from the AMSR-E 89 GHz brightness temperature while the extent of the sea ice was determined by the AMSR-E sea ice concentration. Over the continents, the terrain shows the average land cover for September, 2004. The global cloud cover shown was obtained from the original Blue Marble cloud data distributed in 2002. [Source]

Due to the position of Antarctica in relation to our Sun it would not look like this to the naked eye. This is a composite that shows what Antarctica looks like if the entire continent were illuminated.

## Joshua Tree National Park at night

January 19, 2014

A long exposure, you can tell by the airplane streaks near the horizon.  Walking that fine photography edge of long enough to get the exposure, but short enough not to distort the stars too much.

Long exposure of a Joshua tree, in Joshua Tree National Park. Photo: Sarah Chah (www.sharetheexperience.org)

Viewed from the road, this desert park only hints at its vitality. Closer examination reveals a fascinating variety of plants and animals that make their home in this land shaped by strong winds, unpredictable torrents of rain, and climatic extremes. Dark night skies, a rich cultural history, and surreal geologic features add to the attraction of this place. Come see Joshua Tree National Park for yourself!
