And because of those words, he did look down. And he saw a line. A wide line of darker grey stone which ran from the center of the West Front door to the pulpit. But there was something else there, as well. Something … deeper. Almost like water, shimmering. Somehow under the stone. Infusing the stone. Was it one of the absurd ley lines which St. John had talked about? But Darnell didn’t believe in those.
Or did he?
What did he believe, anymore?
“Look at it with new eyes,” Megan had said. “Try and see it as the believers see it.”
The believers? Or we believers? Did the distinction make sense anymore?
Did it matter?
He stepped onto the line.
Of course, it was like stepping onto any other stone. Solid. Hard. Dependable. Real.
He took another step, along the line of grey. And it was still solid. But now he felt something like a tremor run through the floor. He glanced up at the gorgeous wooden ceiling overhead, and remembered that it was there due to an earthquake which struck the area back in the thirteenth century. And he wondered whether the fault was again active.
But none of the others in the cathedral seemed to notice the tremor. No bells chimed in the distance. The carved panel depiction of the crucifixion high above did not sway.
He took another step, paying close attention. Again, he felt something. But it was less a tremor, and more a slight vibration, a springiness, like stepping onto a taut trampoline or a tightrope. There was a … strumming … but only in response to his steps. This wasn’t a ley line, at least not as he had understood it. It was, rather, a living path.
There’s about 12 hours left in this weekend promotion. About 500 people worldwide have downloaded Communion of Dreams so far … including, for the first time (that I can recall, anyway) 3 downloads in Japan. Pretty cool.
See? It’s free! Today through Sunday! Go get a copy! Tell your friends to go get a copy! Tell your dog to go get a copy! But not your cat. Cats prefer to read the wallpaper. You know how they are.
As something of a follow up to my last post, there’s a great little item about the development of the Drake equation over on National Geographic. Here’s a good passage:
It’s this kind of guesswork that tends to inflame the Drake equation’s critics, those who complain that the equation isn’t predictive, is too open-ended, and doesn’t provide any answers. But “predictive” isn’t really what Drake ever intended.
“It’s a way to frame the problem,” says MIT astrophysicist Sara Seager, about the equation. “In science, you always need an equation—but this isn’t one you’re going to solve. It just helps you dissect everything.”
Definitely worth reading, as well as thinking about.
Sometime when I’m really bored I may go to the trouble to try and figure out when the first variety of this image was made — I remember it back to my childhood (I think … you know how tricky memories are):
Nice little bit of perspective, eh? Which of course is why it has become such a classic image in one form or another.
And that little bit of perspective gives rise to a very nice explanation and exploration of the Fermi Paradox (which I have written about/mentioned many times) over on Wait But Why. Here’s a bit from the closing paragraphs:
As we continue along with our possibly-futile search for extraterrestrial intelligence, I’m not really sure what I’m rooting for. Frankly, learning either that we’re officially alone in the universe or that we’re officially joined by others would be creepy, which is a theme with all of the surreal storylines listed above—whatever the truth actually is, it’s mindblowing.
Beyond its shocking science fiction component, The Fermi Paradox also leaves me with a deep humbling. Not just the normal “Oh yeah, I’m microscopic and my existence lasts for three seconds” humbling that the universe always triggers. The Fermi Paradox brings out a sharper, more personal humbling, one that can only happen after spending hours of research hearing your species’ most renowned scientists present insane theories, change their minds again and again, and wildly contradict each other—reminding us that future generations will look at us the same way we see the ancient people who were sure that the stars were the underside of the dome of heaven, and they’ll think “Wow they really had no idea what was going on.”
Of course, this whole question is at the very heart of Communion of Dreams. And, in a way, also at the heart of St Cybi’s Well. You’ll see.
But for now, go enjoy that post at Wait But Why. It’s quite good.
Darnell shook his head, but peered closer where Eleazar pointed. He could see something faint on the rock, but couldn’t make the image resolve. So he took out his hand-held, removed the stylus. Pointing the stylus camera and the flash on the phone at the image, he tapped an icon on the screen. There were a series of quick flashes, and the screen filled with a close-up of the stone face. Eleazar looked on with some amusement as Darnell used a slider at the bottom of the screen to go up and down the spectrum, changing the image and bringing out details otherwise hidden in it. Darnell glanced up at Eleazar, saw his amusement, and explained “Multispectral imaging. Not nearly the resolution or range of real remote sensing equipment, but handy for some things.”
“Particularly when you’re going blind, eh?”
“Yeah. And until I can find my miracle, this helps.” Darnell smiled slightly, a wry, almost sad smile. “But the range of the image is well beyond what even good human sight can see – what even you can see.”
Some animals, including your pets, may be partially colorblind, and yet certain aspects of their vision are superior to your own. Living creatures’ visual perception of the surrounding world depends on how their eyes process light. Humans are trichromats—meaning that our eyes have three types of the photoreceptors known as cone cells, which are sensitive to the colors red, green, and blue. A different type of photoreceptors, called rods, detect small amounts of light; this allows us to see in the dark. Animals process light differently—some creatures have only two types of photoreceptors, which renders them partially colorblind, some have four, which enables them to see ultraviolet light, and others can detect polarized light, meaning light waves that are oscillating in the same plane.
“None of us can resist thinking that we can imagine what another animal is thinking,” says Thomas Cronin, a professor at the University of Maryland who studies visual physiology. But while guessing animals’ thoughts is a fantasy, looking at the world through their eyes is possible.
The caregiver puts up with that out of love and decency. This book describes these things in the form of daily and weekly accounts as well as diary log pages of personal fear and depression and exasperation and recurring bubbling senses of humor. I loved this because it made me cry and it made me laugh. It’s not all drudgery. It’s hysterically funny at times. But it wouldn’t be funny at all if you didn’t love the patient. This is a book of love…
So often people see the words “Alzheimer’s” or “dementia” or even “care-giving” and just move on, thinking that the book (and the experience) is nothing but darkness and depression. And yeah, there is darkness there, but to borrow a phrase from Communion of Dreams/Heidegger: “That which emerges from darkness gives definition to the light.”
We’re coming up on the three-year publishing anniversary (July 15). If you haven’t yet read Her Final Year go ahead and do so. If you want to wait a month, the Kindle edition will be available for free download around the anniversary.
And if you have read it, please consider posting your own review on Amazon or elsewhere. It helps.
His expert was one of best, one of only a few hundred based on the new semifluid CPU technology that surpassed the best thin-film computers made by the Israelis. But it was a quirky technology, just a few years old, subject to problems that conventional computers didn’t have, and still not entirely understood. Even less settled was whether the experts based on this technology could finally be considered to be true AI. The superconducting gel that was the basis of the semifluid CPU was more alive than not, and the computer was largely self-determining once the projected energy matrix surrounding the gel was initiated by another computer. Building on the initial subsistence program, the computer would learn how to refine and control the matrix to improve its own ‘thinking’. The thin-film computers had long since passed the Turing test, and these semifluid systems seemed to be almost human. But did that constitute sentience? Jon considered it to be a moot point, of interest only to philosophers and ethicists.
And while the problem of consciousness is far from being solved, it is finally being formulated mathematically as a set of problems that researchers can understand, explore and discuss.
Today, Max Tegmark, a theoretical physicist at the Massachusetts Institute of Technology in Cambridge, sets out the fundamental problems that this new way of thinking raises. He shows how these problems can be formulated in terms of quantum mechanics and information theory. And he explains how thinking about consciousness in this way leads to precise questions about the nature of reality that the scientific process of experiment might help to tease apart.
Tegmark’s approach is to think of consciousness as a state of matter, like a solid, a liquid or a gas. “I conjecture that consciousness can be understood as yet another state of matter. Just as there are many types of liquids, there are many types of consciousness,” he says.
Today’s xkcd triggered a thought: that we can think of the challenges of climate change as being akin to a planetary gom jabbar. Do we have the ability to endure short-term pain and survive, or do we give in to our immediate short-term desires and suffer the consequences?
Long training had taught him to put his trust in facts. In objective, testable reality. You didn’t fly a space shuttle – even one which had been stripped down to the bare essentials for transporting sealed sleeper modules – by the seat of your pants. That would very quickly get you killed. You flew it by the book, with close attention to your instrumentation and computer systems. Because your instincts would lie to you. Your hopes and dreams had no place in orbital calculations. The only miracles which existed were the ones created by careful science, proven engineering, and rigorous quality control.
The European Space Agency has put together a fantastic and enthralling video that goes through the steps taken to bring the space travelers down. This is seriously worth 20 minutes of your time.
Yeah, it is really cool to watch them go through it all by the book. Find the time to watch it.
Been a while since I posted an excerpt. Partly that has been due to the fact that a number of different things have conspired to slow down my writing progress the last few weeks. But I finally seem to be making good headway again, and thought I would share a bit from today’s efforts:
Darnell nodded. “Sure. Now let’s take a look at that satellite map.”
He pulled out his phone again, tapped it a couple of times. Soon they were looking down at their current location centered on the map, with the resolution such that Pentre Ifan was off on the very left edge of the screen. St. John pointed at a slightly lopsided ring due north of Craig Rhosyfelin about the same distance from Pentre Ifan. “There. See?”
Darnell zoomed in on the image. The ring expanded until it was about half the size of the screen. It was actually a double ring of trees, bisected by a chevron of a single line of trees. “Yeah, OK. Not a perfect circle. Looks like it has a bit of a pinch on the east side, almost as if pointing that way.”
“Exactly!”
“I’m sorry, I don’t follow you.”
St. John pointed at the screen. “Points due east. That’s because before it was made into a hill fort, there’s evidence to suggest that it was a henge.”
“Huh.” Darnell looked at the image again. “Yeah, I can see that.”
“And I think that it wasn’t just any henge. I think that it was the precursor to Stonehenge.” St. John looked at Darnell, and there was a slightly mad gleam in his eye. “In fact, I think that the henge which was there was disassembled and then transported to Wiltshire and rebuilt as the structure we all know today.”
