purplecat: The Sixth Doctor (Who:Six)
([personal profile] purplecat Jul. 5th, 2025 08:42 am)

Book cover for Doctor Who The Shadow in the Glass by Justing Richards and Stephen Cole.  A blue cover with the faces of the sixth Doctor and Hitler behind a transparent globe.  Blue streaks emanate out from the globe.

I've no memory of reading this at all. The back makes it sound both interesting and memorable - a retired brigadier stumbling upon shenanigans from WW2 recruiting the sixth Doctor for help. Richards and Cole are both solid Doctor Who authors who I rate but none of it stirs a memory.
jadelennox: Westing Game: a chess queen, a purple chessboard, fireworks, BOOM! (chlit: westing game:  boom)
([personal profile] jadelennox Jul. 4th, 2025 10:33 pm)

I've been trying very hard to cheerful!post this week because I'm frequently struggling to breathe, as one does these days. You all know how it is. I was planning on posting from the perfect 4 July book (The Westing Game). But when I looked at the exact words of the quotation, it felt much too on the nose:

The sun has set on your Uncle Sam. Happy birthday, Crow. And to all of my heirs, a very happy Fourth of July.

So, okay, I thinks to myself. I'll quote my other favorite Fourth of July bit from the end. But when I looked it up, uh. That didn't feel any less apropos to the moment?

Turtle?"

"I'm right here, Sandy." She took his hand.

"Turtle, tell Crow to pray for me."

His hands turned cold, not smooth, not waxy, just very, very cold.

Turtle turned to the window. The sun was rising out of Lake Michigan. It was tomorrow. It was the Fourth of July.

Ah, well. Ready for a nice game of chess?

Summary Author: Ray Boren

Almost two centuries ago, on July 4, 1830, a brigade of about 80 fur trappers and traders led by William Sublette, headed toward the Wind River region just to the west, paused to celebrate the Fourth of July — Independence Day in the young United States of America. They camped beside a massive, free-standing mound of bald granite along central Wyoming’s Sweetwater River. Sublette is generally credited with giving the monolith its name: Independence Rock, shown here in a photograph taken on June 19, 2025.

During the mid-19th century, this emigrant route over the Continental Divide and through North America’s Rocky Mountains was traveled by an estimated half-million explorers, adventurers, would-be gold miners, farmers, tradesmen and other settlers — men, women and children. All were walking, riding horses or seated on often oxen-powered wagons, and some were even pulling handcarts. The Oregon, Mormon Pioneer and California National Historic Trails and the route of the Pony Express all passed by this impressive outcrop. Independence Rock and the Fourth of July became goals for pioneers because the landmark was about halfway between their trek’s beginnings, near the Missouri River, and their Far West and Pacific Coast destinations, which they hoped to reach before snow started to fall in the Sierra Nevadas and other ranges later in the year.

In diaries and letters, emigrants variously wrote that the great mound looked like “a huge whale,” “a giant bowl turned upside down,” or “a big elephant mired up to its sides in the mud.” And on cliffs, in alcoves and caves, and on the rock’s rounded top, thousands of them scratched, chiseled or wrote with paint, axle grease, or tar their names, initials and dates onto the granite. Time, weather, erosion and rock-covering lichen have erased or obscured most of the inscriptions, but scores remain, as shown in the bottom photo (also taken on June 19). One of the earliest known signatures, made by “M.K. Hugh” in 1824, has vanished. But others, even from the 1840s and 1850s, can be found by determined searchers, especially along a path that encircles the rock.

The emigrants, as an informational sign at Independence Rock observes, probably did not realize they were beneficiaries of millions of years of geologic activity. The monolith — roughly 1,900 feet (580 meters) long, 850 feet (260 m) wide, and 130 feet (40 m) high — and other, more-jagged peaks nearby are composed of Archean granite, a hard, coarse-grained igneous rock that slowly cooled under the Earth’s surface. The rise and fall of the land and erosion eventually exposed the summits we see today. A highway rest stop along Wyoming 220 now provides viewpoints and pathways to the steep-sided mount, which was designated a National Historic Landmark in 1961, and which is managed today by the State of Wyoming as the Independence Rock State Historic Site

We had a "free" day in Cusco, but there were some suggestions of activities that our guide could organise for us. Two other people in the group were interested in seeing the Moray Ruins and the Salt Mines of Maras and we were happy to tag along and make the excursion cheaper.

Moray was the first Inca Plant laboratory we encountered. As noted previously, it wasn't quite clear to us why it earned the status of laboratory.

Pictures under the Cut )

The Salt Mines are not actually mines, but a salt extraction plant that predates the arrival of the Spanish and which are still worked today. Mineral rich water from the mountains comes in and fills clay lined pools. The water then evaporates and the salt is collected. They are owned by 300 families and there were people working them - flattening the clay lining - when we visited. I bought salt.

The ISS and Space X Dragon Capsule

Photographer: Greg Parker

Summary Author: Greg Parker

On March 16, 2025, probably around 8:00 pm local time, I stepped outside to have a look at the sky. It was fairly clear with only a few patches of clouds. As I looked almost overhead there was the International Space Station (ISS) passing over, a nice long pass of at least six minutes, I would guess. But then as the ISS was about to disappear towards the east there was another bright object following in its path, maybe just a minute or two behind. I couldn't believe it - it was the Space X Dragon capsule about to relieve Suni Williams and Butch Wilmore from their extended ISS stay! I had no idea that this was going on and it was pure fluke I was outside at this time to witness it. Both passes were however on NASA's Spot the Station website with the time in agreement with what I'd seen. I was furious at missing this superb photo-opportunity because at 8:00 pm the sky was nice and dark, and I could have held the shutter open for the duration of both passes. 
 
Two days later, on March 18, the SpaceX capsule was in the news once more as it was about to detach from the ISS and return home. I wondered, could I save the situation and actually get images of the ISS and the SpaceX capsule on the night of the 18th? I should say at this point that there was no entry for the SpaceX capsule's return when I looked at the NASA website on the 16th. But when I checked the site again on the 18th, there it was! The only problem was that the SpaceX capsule pass would occur shortly before 7:00 pm, with the ISS pass coming along some 15 minutes later, and the sky was still fairly bright that early in the evening. This is a nuisance for a photographer as it means I'd have to grab the passes in short exposures as a long exposure would wipe them out due to too much skyglow. In addition, to make things worse, SpaceX pass was fairly low in the sky, in the murk, which combined with the much dimmer appearance of SpaceX (compared to the ISS) and the skyglow would make this a VERY difficult capture -- much more so than the capture two days earlier.  
 
Anyway, I set up my Canon 5D camera in bulb mode with a 15mm fisheye lens ready to capture SpaceX first. In the SpaceX image (top photo) west is to the right and you can see the 11 exposures capturing the SpaceX pass -- at left (east) in the lower half of the frame.  Note that the tree you see on the right in this image is the same tree you see on the right in the ISS pass (bottom photo), which gives you some idea of the huge difference in elevation between the two passes. From memory, I believe the SpaceX pass was around 12 degrees, whereas the ISS pass was around 78 degrees. Some 15 minutes later, the ISS came over and you can see the six (longer) exposures I took on the bottom photo. So, at least I captured both the ISS and SpaceX and was thus a little less furious about losing the more ideal passes two days earlier.
 
But then there was a further setback. When I looked at the SpaceX data, the capsule was incredibly dim, and I couldn't create even a half decent image of the pass. I was down in the dumps again. Had I missed the photo-opportunity of a lifetime for a second time? Fortunately, not! My friend Noel Carboni, Photoshop practitioner extraordinaire came to the rescue and created the top image (of the two) that you see above.

Icarus and the Equinox Sun

Solar-scenic-cyprus-ayia-napa-icarus-20220409

Photographer: Anthony Ayiomamitis

Summary Author: Anthony Ayiomamitis 

One of the most beloved myths from Ancient Greece involves the father-son duo of Daedalus and Icarus who were jailed by King Minos in Crete after the latter had asked for the construction of a complex labyrinth by the crafty Daedalus for the jailing of the Minotaur (illegitimate son of the King's wife).



The older Daedalus came up with the ingenious idea to construct wings made of wax and bird feathers so that he and his son could fly their way out of prison and away from Crete. Prior to their dramatic escape, Daedalus advised the younger Icarus not to fly too close to the Sun since the heat would melt the wax and lead them to their demise. Similarly, he advised Icarus not to fly too close to the sea since the moisture would dampen their wings, thus making them heavier and which would also lead to a destructive ending.



Although the escape went as planned, the younger Icarus was so excited by their ability to fly that he soon forgot his father's advice by flying higher and higher and which eventually led to the melting of the wax and his ultimate demise where he tragically fell into the Aegean Sea. Daedalus located his son's body and buried Icarus in the immediate vicinity of his tragic drowning and named the nearby island Icaria in honor of his cherished son.



Featured above (at top) is a stunning stainless steel statue depicting Icarus with the spring equinox Sun setting in the immediate background. The bottom photo required seven trips to Cyprus to get the alignment just right because of the greater distance from the statue than the top photo as well as various nuances due to the weather and a broken tripod connection. Top photo taken on April 9, 2002; bottom photo taken on March 15, 2025.

I just finished watching John Green's latest video, in which he talks about the vagaries of the NYT bestseller list and how you will miss out on a lot of excellent books if you use that as your primary source of book recommendations. So that got me to wondering how other people discover the books that they want to read.

Personally, I am such a F/SF devotee that a huge number of the books I end up checking out are sourced directly from Tor's lists of new releases. They publish the lion's share of my current favorite authors and seem to be responsible for the majority of recent Hugo nominees.

I also rely heavily on my local libraries. There are two in particular with good F/SF sections and I am able to find most of the books that I want to read in their collections instead of having to purchase them. I also regularly browse their nonfiction new releases and recommendations for younger readers.

The other major source of recommendations for me is social media - mostly you all here on Dreamwidth, but also Bluesky, Facebook, and Discord. I'm always paying attention to what my friends are into.

Occasionally I'll see an interesting book on the shelf at Target or Barnes & Noble, but I'm not located near any independent bookstores, alas.

It turns out that those of us living in the mid and low latitudes have only been seeing half of the Moon's trajectory! We're used to the Moon rising in the east and setting in the west. If we observe closely, we'll notice that its path shifts north and south every month, while the Sun only shifts north and south once a year. From February 22 to March 7, 2025, I traveled to northern Norway, around 69 degrees north latitude. The first few days I was there, I found that I couldn't see the Moon at all, day or night. It then dawned on me that because of how far north I was, the Moon's path was too far south for me to see. 

However, in the latter half of the trip, on March 4 and 5, I discovered that the waxing crescent Moon stayed in the sky all day and night! In fact, if the weather was clear enough, we could observe this waxing crescent remaining near the level of the horizon for five to six days, much like the phenomenon of the Midnight Sun during the summer solstice, where in the vicinity of the Arctic Circle the Sun stays on the horizon continuously.

Unfortunately, due to the weather and my travel schedule, I couldn’t capture the entire trajectory of the Moon across the sky. But during the early hours of March 5, while photographing an aurora, I managed to capture two segments of the Moon's path. The left image shows the time from 12:30 to 1:52 am (local time) on March 5, and the right image is from 2:48 to 4:07 am. In the left image, the Moon is still descending, while in the right image, it appears to be moving horizontally just above the horizon. From the position of the North Star (at the center of the concentric circles), we can see that the Moon has reached its lowest point and is beginning to rise again, though the movement is so subtle it’s almost imperceptible.

Additionally, the Moon that appeared in the northern low sky at this late hour was a waxing crescent Moon, which shouldn't have been visible at this time and direction. This phenomenon, where the Moon never sets, is actually the other half of the Moon's trajectory below the horizon. It's a sight that people living in the mid to low latitudes have never imagined and is truly fascinating! Photos taken on March 3, 2025.

Siberian-driftwood-collecti

This EPOD was first published May 16, 2012

Photographer: Rebecca Roush

Summary Author: Stu Witmer



The photo above shows a stack of driftwood on the beach of the bay of Hunafloi near Drangsnes, in the Westfjords district of Iceland. This is no casual bonfire in the making. Trees are few in Iceland. So much so that a popular joke for tourists is “What should you do if you’re lost in the forest? Stand up.” Most of the native trees were cut down in the early days of settlement and a reforestation program is underway to help bring the forests back. Meanwhile, driftwood fills the gap. There’s more driftwood than you might expect. Primarily spruce (Picea), pine (Pinus) and larch (Larix sibirica) the majority of these trees originally stood along Siberian rivers such as the Ob and the Lena where they may have eroded from the shores or escaped from logging operations. Once at sea, the trees drift with the Arctic Ocean currents. Studies have shown that it takes about five years for these trees to travel to Iceland. Driftwood can only stay afloat for about ten months indicating that these trees are primarily carried by sea ice. Along the way, the wood becomes impregnated with so much salt from the seawater that it is hardened thus making it excellent for use in construction. These days it is mainly used for fence posts. Since the wood belongs to whoever owns the land it washes up on, it makes a cost-effective building material and sometimes a cash crop. Photo taken September 13, 2011.

"Academia: Staying Afloat" by Timothy Burke from the end of January made me feel warmer. It's about everything. AI slop. Fascism. Modern employment. Greed. The broad gesture at everything. Hope. Determination.

You are the right person to do what you do, know what you know, study what you’re going to study. You do it.

You are a lifeboat.

You are not the passenger being rescued from a shipwreck. You are the rescuer. Your skills, your knowledge, your experience reside in you. You have pulled them from the cold ocean where cruel and careless captains have set them adrift.

Photographer: Ray Boren

Summary Author: Ray Boren

Under a big blue sky, the morning sun illuminates a central portion of Wyoming’s majestic Teton Range, which is mirrored via specular reflection in a calm and equally blue bay of Jackson Lake in Grand Teton National Park. In this photograph, taken on May 23, 2025, the park’s namesake Grand Teton peak, topping out at 13,775 feet (4,199 meters) above sea level, is on the far-left side of the image, to the south. Blocky Mount Moran (12,610 feet; 3,840 m) rises prominently just left of center. 

The snow still covering the Tetons on this spring day makes it easy to envision the Pleistocene ice-age glaciers that helped carve the mountains’ jagged summits, cirques, and U-shaped drainages. The Park Service explains that the Teton Fault began tilting the range’s primarily granite mountain block upward about 10 million years ago while also dropping the valley of Jackson Hole. Although masked by snow in the photograph, almost a dozen glaciers remain in the park today, some moving and some mere remnants. They, and erosion from water, wind and gravity, continue to shape the dramatic terrain.

Our Inca Trail holiday actually started with three days spent in and around Cusco, the ancient Inca Capital. Our first day started with a walking tour of Cusco. Because of the various mix-ups with permits, this was with a guide called Arturo who should have been our guide for the whole trip, but wasn't.
