Communion Of Dreams


Pennies in heaven.

Well, a single penny, anyway. And it’s on Mars. But you know what I mean.

Cool story:

Rare Coin Found on Mars!

It’s true.  At this moment there is a rare coin on Mars.  Specifically, the coin is a 1909 ”V.D.B.” Lincoln-head American penny.

The question is, why is this penny on Mars?

 

Go read it and find out.

Several things …

First, thanks again to one and all for helping to make my recent promotion a success! We did finish the weekend with just under 500 total downloads worldwide. Yay!

In addition, there’s a new review up over on Amazon. Here’s how it starts:

4.0 out of 5 stars A good story, and an excellent first novel.

This kept me interested until it was finally done.
For a first novel it was very good.
There were a couple of awkward sentences I had to re-read, but most books have that.
The plot was good, and different.

I am a bit amused that some people focus in on the “first novel” thing, and sometimes it seems that they feel like they can’t give a 5-star rating just on that basis. But perhaps they’re just trying to be nice in comments. If you have a chance, and haven’t yet done so, please consider posting your own review on Amazon (or elsewhere). Thanks!

There have been a couple of fairly scary pandemic stories in the news lately. One which has gotten a lot of attention is the Ebola outbreak, and how it has spread more than previous outbreaks. One which is even more frightening (to me) is word of an accidental anthrax exposure which went undetected for upwards of a week at a major supposedly secure research lab, the CDC bioterrorism facility in Atlanta. From one article:

Unfortunately, such scenarios are very real threats to not just lab workers but to the general population should a deadly contagion escape undetected the same way the CDC anthrax exposure remained undetected for possibly an entire week. That much time lapse for a deadly viral infection could prove devastating to the world population.

 

As it turns out, I am right at the point in St Cybi’s Well when first reports of the fireflu outbreak has hit the news. At first it is thought to be a Sarin gas attack at Hartsfield–Jackson International Airport in Atlanta. From the book:

“Jay, I’m here at the Georgia International Convention Center, just west of the airport. Authorities have turned this into something of a command center for the developing crisis, since they have put the entire airport terminal on lock-down.” She was reporting from a large, open room. In the background there was a stage and podium, where a small knot of government officials were standing and taking turns addressing the crowd of reporters and film crews down on the floor in front of them. “As you can imagine, the situation here is very confused at present, with conflicting reports coming from the airport itself about how many people have been injured in the attack, when it likely happened, how it was detected, and what steps are being taken to protect the public. What is certain is that while this airport – one of the busiest in the world – always has a number of arriving and departing flights, that the attack came sometime late at night has meant that the number of victims is much smaller than it could have been. We’re due to receive an update on the situation at 3:00 AM local time, which is in about an hour and fifteen minutes. Back to you.”

 

Serendipity. Scary, scary serendipity.

Edited to add this tasty tidbit of news which broke just in the last hour:

Smallpox Virus Found in Unsecured NIH Lab

Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: Vials labeled “variola” – in other words, smallpox.

* * *

In a statement Tuesday, the agency said scientists did indeed find smallpox DNA in the vials. Scientists are now testing the sample to see whether any of the is still capable of causing disease. That testing will take two weeks.

The laboratory on the NIH campus had been transferred to the Food and Drug Administration in 1972. It was being cleaned out as the FDA was preparing to move that lab to its main campus.

 

Yeah baby!

“It’s a way to frame the problem,”

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.

You are here.*

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.

Vast vision must improve our sight.*

Remember this from a post a couple months back?

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.”

 

A cool article with some very fun interactive tools to see how the different ranges of animal eyes compare to ours:

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.

A state of matter, or a state of mind?

From page six of Communion of Dreams:

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, perhaps, physicists:

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.

 

Good article. Read the whole thing.

It’s a test.

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?

By the book.

From Chapter 7 of St. Cybi’s Well:

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.

 

And from a great entry today on Bad Astronomy:

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.

 

Jim Downey



Of course they do.

From Chapter 1 of Communion of Dreams:

“I’ve had my expert do a preliminary search through the old NASA archives. I recalled that they had protocols for dealing with such possible situations, and I doubt that anyone else has really thought much about it since the turn of the century.

“In addition to Don’s field team, the preliminary search suggests that another component should be theoretical, a mix of disciplines so that we can get as broad a spectrum of experience and mind-set as possible. Probably we should have an expert in computer technology. A cultural anthropologist. Someone with a background in game theory and communication strategy. An artist or two. We’ll see if a more thorough survey of the NASA material has any good suggestions beyond that. I’ll get to work identifying appropriate individuals.”

 

Well, guess what news was announced last week:

During the past few years, NASA has released a series of free ebooks, including NASA Earth As Art and various interactive texts focusing on the Webb and Hubble space telescopes. Last week, they added a new, curious book to the collection, Archaeology, Anthropology, and Interstellar Communication. Edited by Douglas A. Vakoch (the Director of Interstellar Message Composition at the SETI Institute), the text contemplates how we’ll go about “establishing meaningful communication with an extraterrestrial intelligence.” The scholars contributing to the volume “grappl[e] with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected.” And to make sure that we’re “prepared for contact with an extraterrestrial civilization, should that day ever come,” they draw on “issues at the core of contemporary archaeology and anthropology.” Why archaeology and anthropology? Because, says Vackoch, communication with intelligent life probably won’t be through sound, but through images. We will need to read/understand the civilization we encounter based on what we observe.

 

Heh. I love seeing this stuff happen.

This is a big deal.

Short paragraph. Big implications:

Abstract

Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.

 

Decent explanation (at least from what I know) in this article. Excerpt:

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

 

Ten feet may not sound like much, but it is a huge increase — previously, reliable teleportation of information was on the scale of just billionths of a meter. This change opens the door to functional quantum computing, which would have the same relation to current computing power that current computing power has to mechanical calculating machines of about the WWII era.
