Communion Of Dreams


Three weeks in Wales, Part 5: water and old stone.

Part 1. Part 2. Part 3. Part 4.

“Water and old stone” pretty much sums up Wales, for me, I think. But I have an admittedly biased perspective.

We started the next morning with a trip to Pennant Melangell, a small pilgrimage church in the Tanat valley in north Wales. Here’s the preamble I use in the first chapter of St Cybi’s Well, which is titled ‘Pennant Melangell’:

Melangell was a female saint of the 7th century. According to tradition she came here from Ireland and lived as a hermit in the valley. One day Brochwel, Prince of Powys, was hunting and pursued a hare which took refuge under Melangell’s cloak. The Prince’s hounds fled, and he was moved by her courage and sanctity. He gave her the valley as a place of sanctuary, and Melangell became Abbess of a small religious community. After her death her memory continued to be honoured, and Pennant Melangell has been a place of pilgrimage for many centuries. Melangell remains the patron saint of hares.

It’s a wonderful little place.

Here’s the entrance to the churchyard, with the classic lych gate:

I love this place. Maybe it shows:

We got some lunch in the charming little town of Llanrhaeadr-ym-Mochnant (where parts of this favorite movie was shot), then went to visit Pistyll Rhaeadr, one of the “seven natural wonders of Wales.”  The waterfall is mentioned in Communion of Dreams, and one of the major chapters of St Cybi’s Well is titled ‘Pistyll Rhaeadr’. Here it is:

That’s almost 250′ tall.

Up on top.

 

Steve, getting some images of the falls, looking down.

I did the same:

Here’s a description of the top of the falls, taken from St Cybi’s Well:

As he came around past the rock outcrop, the sound from the falls increased. There was the distant rumble from the bottom of the first long drop, but closer now were the sounds of water scrambling over rock and root, gathering in the small pools at the top before the plunge. Darnell made his way to the last of these pools, near the edge of the cliff, and stood there, listening.

He closed his eyes, took a deep breath, and relaxed, opening himself as he had tried to do at St Cybi’s and St Seiriol’s, allowing rather than reaching, feeling rather than thinking.

And he felt something. A whisper in his mind. A whisper as though someone were speaking his name. A whisper of invitation, to step through the wind and over the edge of the cliff, to come to freedom. It was a beckoning, a subtle and supple call to pass through to the other side.

This was the thinness Megan spoke of. He understood it now, at least a little.

Releasing the breath, he slowly opened his eyes, then knelt down to the pool in front of him. The silver-grey sky reflected in the pool had a new shimmer to it, an intensity he had not seen before. He reached out, as he had done before, and placed the palm of his hand against the surface of the water.

There was no slight electric thrill, but neither was there just the crisp coldness of a mountain stream. Rather, there was a vibrancy, almost a … depth … there, more than the few inches of water in the pool would suggest. And while the roar of the falls to his left called loudly, it was the trickle of water coming from his right which whispered to him. He stood, and followed it further up the mountain.

After hiking back down to the base of the falls, we enjoyed a snack in the little tea shop, then headed back to our cottage. The magic of the day continued, as we watched clouds form midway down the mountain:

The next day we decided to visit Caernarfon castle, the massive fortress in the north Wales town of the same name. This one:

Some of my images:

And from displays inside one of the main towers:

Time enjoying the castle was followed up with lunch on the castle square:

That afternoon, we went to St Cybi’s Well, itself:

This is completely delightful:

 

Lots of news from the world of my life. Most of it good. I’ll share in a few days.

Llangelynnin

The title of the next chapter is “Llangelynnin” (which refers to the church/churchyard, rather than just the holy well at this site — this is a change from what I had originally planned), and in doing a little research I found this nice bit of video:

 

The holy well isn’t shown in this video, but is basically directly below the drone at about the 0:13 mark. It can be seen at the very southern point of the wall enclosure here, and in an image in this entry. Some of my source material is drawn from this travelogue from 2006 (towards the bottom of that post). And I think the video gives a very nice feel for the remoteness of the site, and why I have wanted to include it in the story I am telling.

Oh, I haven’t said in a while, but I now have approximately 85,000 words written (that’s actual novel, not including notes or reference material), with about 25,000 – 30,000 to go before I’m finished (and a fair amount of that is partially done already in notes and reference material). So I’m not in the closing stretch, but am getting there. It’s progress, anyway.

“Uh, he’s already got one, you see.”

Happy 25th Anniversary to the Hubble Space Telescope, which has rightly been called one of the most important scientific tools in human history. It has brought the cosmos closer to us, just as it has helped to drive home an understanding of precisely how far away those twinkling lights in the sky actually are … and connected to that, just how old our universe is:

The depth of Hubble’s data, however, has touched or rewritten nearly every area of astrophysics. Ever since the discovery of the expanding universe in the 1920s, astronomers had struggled with the rate of expansion and what it means. The so-called Hubble constant, the universal rate of expansion, was much in doubt, with two factions arguing very different conclusions from the data. The Hubble constant is also inversely proportional to the age of the universe, another key holy grail of science. One of the primary goals of Hubble was to measure the Hubble constant accurately, using a variety of distance indicators, and by the turn of the 21st century, this helped define a relatively accurate Hubble constant of 72±8 and an age of the universe, which the more recent European Planck satellite has refined further to 13.8±0.04 billion years.

 

It’s an amazing piece of technology.

But I can’t help remembering that even as amazing as it is, a few years ago it was revealed that it was considered so … obsolete … that US spy agencies had just given NASA two other surplus Hubble-type instruments they no longer wanted to bother to store. As I noted at the time:

…we’ve just found out that what we thought was at the limits of our technology is so obsolete that it can be handed off as so much surplus junk. And the implication is that while NASA is currently without the means to launch and service something like Hubble, that there are plenty other agencies within our government which are not so inconvenienced.

 

Which brings me around to the title of this blog post. Monty Python fans may recognize it from this scene in the Holy Grail:

Which I just happened to watch this week, and snickered over, remembering the news item about the HST from 2012. Though of course, in this case I hope that the National Reconnaissance Office wasn’t *quite* so taunting of NASA …

Damn, that’s FAST.

Watch a laser beam bounce:

From the YouTube description:

A video captured by Washington University’s Lihong Wang’s new imaging system, known as “compressed ultrafast photography,” shows a laser pulse propagating in air and being reflected from a mirror. The movie is slowed down 10 billion times to make it visible to the human eye. (Video courtesy of Washington University in St. Louis)

A good article explaining this new technology is here:

New Ultrafast Camera Invented At Washington University Could Help Turn Science Fiction Into Reality

Very cool. Take-away quote:

Wang’s new technology improves on previous ultrafast cameras in two important ways.

Up until now, streak cameras could only take a one-dimensional snapshot ― think of it like trying to take a picture of something flying by really fast behind a vertical slit.

And the fastest cameras had to have an external light source to work.

Wang’s technique doesn’t need special lighting, and it produces two-dimensional images ― more like a regular photograph ― but at a rate of one every 10 trillionths of a second.

Damn, that’s FAST.

And the sky, full of stars … *

I should have some interesting news to share in a couple of days. But for now, I thought I would share this amazing post from Phil Plait at Bad Astronomy:

Andromeda

Yesterday, I posted an amazing Hubble Space Telescope picture. I don’t think it’s too soon to post another shot from Hubble… and I think you’ll agree when you see it, especially after you get an understanding of what you’re seeing.

First, the eye candy: The magnificent Andromeda Galaxy, as seen by Hubble.

 

And as Plait notes, that’s the low-resolution image.

Go enjoy the article, and marvel at the images he has/links to. Seriously — it is worth your while, if you’re any kind of a space-geek at all.

Spinning wheels, got to go ’round.*

The reviews have been mixed, but one aspect of the new movie Interstellar is pretty cool: the rendering of the black hole depicted in the movie.  Even moreso since it is as scientifically accurate as possible, based on close collaboration with noted astrophysicist Kip Thorne:

Still, no one knew exactly what a black hole would look like until they actually built one. Light, temporarily trapped around the black hole, produced an unexpectedly complex fingerprint pattern near the black hole’s shadow. And the glowing accretion disk appeared above the black hole, below the black hole, and in front of it. “I never expected that,” Thorne says. “Eugénie just did the simulations and said, ‘Hey, this is what I got.’ It was just amazing.”

In the end, Nolan got elegant images that advance the story. Thorne got a movie that teaches a mass audience some real, accurate science. But he also got something he didn’t expect: a scientific discovery. “This is our observational data,” he says of the movie’s visualizations. “That’s the way nature behaves. Period.” Thorne says he can get at least two published articles out of it.

The video is remarkable. Seriously. Go watch it.

And in a nice bit of serendipity, there’s another fantastic bit of astrophysics in the news just now: actual images of planetary genesis from ALMA. Check it out:

A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart [1]. This new result represents an enormous step forward in the understanding of how protoplanetary discs develop and how planets form.

ALMA has obtained its most detailed image yet showing the structure of the disc around HL Tau [2], a million-year-old Sun-like star located approximately 450 light-years from Earth in the constellation of Taurus. The image exceeds all expectations and reveals a series of concentric and bright rings, separated by gaps.

 

That’s not computer-rendered theory. That’s an actual image, showing the formation of planets around this very young star.

Wow.
