Communion Of Dreams


That’s just cool.

Via BoingBoing, fun video from NASA of the unboxing of a shipment of the first printed tools and tests parts from the ISS:

Perhaps it’s just the conservator in me, but I loved the documentation process, and how they’re going through everything carefully. No doubt that some or all of those items will eventually wind up at the Smithsonian Air & Space Museum.

“You’re oversharing again, Earth.”

Seth Shostak, on the topic of how to introduce ourselves to our neighbors:

A better approach is to note that the nearest intelligent extraterrestrials are likely to be at least dozens of light-years away. Even assuming that active SETI provokes a reply, it won’t be breezy conversation. Simple back-and-forth exchanges would take decades. This suggests that we should abandon the “greeting card” format of previous signaling schemes, and offer the aliens Big Data.

For example, we could transmit the contents of the Internet. Such a large corpus — with its text, pictures, videos and sounds — would allow clever extraterrestrials to decipher much about our society, and even formulate questions that could be answered with the material in hand.

 

While I still agree with Stephen Hawking on the idea of ‘active SETI’, I think that there’s merit in the idea of exposing other nearby civilizations to what we’re really like, warts and all. Because as soon as they decoded our transmissions well enough to understand the comments section of pretty much any major site on the web, they’d either completely wall off our solar system* and post warnings around it or just trigger our sun to go supernova. Either way, we’d never know what happened, and the rest of the galaxy would be safe …

*gee, that’d make an interesting premise for a SF novel, doncha think?



Another step.

From page two of Communion of Dreams:

He paused there at the railing, right hand manipulating the thin-film controls under the skin on the back of his left hand. Looking out over the herd of slowly moving animals, a see-through display came up before him. Nothing new on the nets. So, whatever the emergency was, it wasn’t public knowledge yet. He turned, opened the door to the station, and stepped inside.

From a new article on Wired this morning:

Gannon is exploring modeling techniques that use the human skin as their primary interface. Her prototype is called Tactum. Instead of creating free-floating models in software like CAD, Gannon’s setup uses a Kinect camera and a projector to create a virtual modeling environment right on your hand.

The projector beams blue lights onto the skin. That light represents the base geometry of the band you’ll eventually wear. The Kinect tracks your body and space and keeps the projection aligned. To adjust the design, you drag it with your fingers; there’s no layer of mediation, you just manipulate the form directly. “You could be pinching, touching, poking, prodding and that visual geometry on your arm without having to go through any computer,” Gannon says. “Your skin and hand are the equivalent of the mouse and keyboard.”

Another step in Communion of Dreams becoming reality.

So I wander into this nuclear reactor . . .

I had reason to look up this item the other day, and was surprised that I hadn’t ever posted it to the blog. So, in honor of St Pat’s Day (well, OK, not really, but there is a connection…), here’s a little something from my old archives from a few years ago.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So I wander into this nuclear reactor . . .

This morning’s news that the NRC has declined to force nuclear power plants to take additional precautions to prevent the breach of a nuclear reactor’s core by attack with a jetliner comes as little surprise, given the Bush administration’s attitudes about actual security issues.

But, as always when I hear such news reports, I was taken back to a sunny spring morning some 30 years ago, when me and a couple of college buddies wandered into a nuclear reactor.

It was the weekend of St. Pats day, and we were at the University of Missouri – Rolla to party with a friend of ours who was an engineering student there.  I think it was Friday morning, and our friend had some classes he had to attend, so myself and my two friends decided to just explore the campus a bit (we all attended schools elsewhere).

I had considered Rolla for school myself a few years previously, when I had been thinking of going into physics (a dream derailed by poor higher-math skills).  So when we came across the research reactor building, I wanted to have a look.

We just wandered in.  No, seriously.  We just wandered into the building, through a couple of sets of doors, and soon found ourselves standing at a railing, looking down at the glowing blue core of the nuclear reactor.  In this day and age it is hard to imagine such a thing – and even at the time it seemed more than a little odd.

A few minutes after we came in, a nice fellow who fit the stereotype image of a science professor came over to us.  Short, grey, bearded, balding, wearing a white lab smock over his shirt and jeans.  He sort of looked us over, asked what we were up to . . . and then gave us an impromptu tour of the place (after tagging us with personal dosimeters).

It was fascinating, to me at least.  The reactor core at this facility sits at the bottom of a large swimming pool, about 20 feet down.  That provides all the necessary protection from the radiation generated from operation of the fission reactor (which doesn’t produce much power, and doesn’t use the sort of fuel used in nuclear weapons).  Herr Doktor explained all this to us non-scientists, and also explained the eerie blue glow coming off the reactor (which was then in operation).

It was a color like I’ve never seen before or since – a soft electric blue that was both intriguing and repulsive.  I knew what it was, having been interested in physics:  Cherenkov radiation, caused when the radioactive particles generated by the fission reactions are faster than the speed of light in the water.  But it’s the sort of thing that lasts in the memory, embedded there in a way not unlike a religious experience – hard to describe, or explain, or convince others of, yet extremely vivid for the one who experienced it.

Now, I’m not religious.  I’m an atheist, in fact.  I understand what that blue glow is – yet, whenever someone claims that they have had a religious experience, I can tie it to that same feeling I had on first seeing that other-worldly blue glow.

Well, anyway, I had to share that personal experience, and add a bit of perspective on the changes we’ve seen in terms of security over the last 30 years.

And for today’s nightmare fuel …

… courtesy of Boston Dynamics:

Don’t get me wrong — that’s extremely cool technology. And I can think of all kinds of incredible applications even just as it is, let alone what it promises for the future.

But it also gives me the heebie-jeebies watching it move.

Bits & pieces.

A number of unrelated items which I thought I’d share …

Astronomers Find Ancient Earth-Sized Planets in Our Galactic Backyard

Astronomers have announced what may be the most interesting exoplanet discovery yet made: five planets, all smaller than Earth, orbiting a very ancient star. And I do mean ancient: Its age is estimated to be more than 11 billion years old, far older than the Sun. These are old, old planets!

* * *

Perhaps you see the problem. If planets like Earth formed 11 billion years ago, and happened to form at the right distance for more clement conditions on the surface, life could have arisen long enough ago and started building spaceships long before the Earth even formed! They’d have planted their flags on every Earth-sized habitable planet in the Milky Way by now.

Where are they?

Oh! Oh! I know! Pick me!!

* * *

Thanks to all who helped spread the word about the 3rd anniversary promotion! It was a modest success, with a little shy of 200 books downloaded world-wide, including through the following Amazon portals:

  • Australia
  • Canada
  • France
  • Germany
  • India
  • Japan
  • Netherlands (for the first time!)
  • UK
  • US

Via BoingBoing, turn your iPhone into a thermal imaging camera in just seconds:

https://www.youtube.com/watch?v=_ZbFjfKn9Cw&x-yt-ts=1422327029&x-yt-cl=84838260

Yeah, I mentioned using this kind of imaging tech in the current novel some time back.

* * *

Speaking of tech predictions, this is the first step in the sort of thing I envisioned for the cyberware of Communion of Dreams:

Flexible spinal cord implants will let paralyzed people walk

* * *

I mentioned earlier that evidently the Wikipedia elves are trying to decide whether to nuke my entry there. It seems that they’re still debating it. As I noted on the BBTI Facebook page a few days ago, in response to comment by a friend that it seems weird that BBTI is little more than a footnote in that entry:

It’s a fair point. I certainly am known much better around the world for being the driving force behind BBTI than I am for a fun little art stunt which was intended to happen and then fade from memory. I know that BBTI has had a much bigger and more lasting impact in the real world.

So, whether or not an entry about me should exist at all, if one does exist, shouldn’t it be more about my part in BBTI rather than as a “internet performance artist”? Hell, even my work as a book & document conservator has had a much larger real impact than ‘Paint the Moon’ did.

Just a thought, if anyone wants to do some editing …

* * *

This doesn’t have anything to do with any of the books or anything I’ve predicted (that I can remember), but it is a pretty cool bit of astronomy:

Gigantic ring system around J1407b much larger, heavier than Saturn’s

Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn. The ring system – the first of its kind to be found outside our solar system – was discovered in 2012 by a team led by Rochester’s Eric Mamajek.

And here’s a useful video for anyone out there who may need to remove some rust from old equipment:

I knew that this could be done with electrolysis, but I didn’t realize that it was actually quite so simple. I am definitely going to set up to do this on a number of old tools and suchlike.

* * *

A nice bit of space exploration history:

The Challenge of the Planets, Part Three: Gravity

And I think I will leave it at that for now.

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.

Sights and insights.

A mix of little things, playing catch-up for the last couple of weeks …

Why catch-up? Well, this might explain why I took a break for a while there.

And we’re off …

* * *

First thing, thanks to all who downloaded Communion of Dreams over the weekend, or helped to spread the word about it. There were a total of 693 downloads worldwide — and that includes various European portals, as well as Canada, India, and Japan! Pretty cool.

For those who have gotten the book, once you have a chance to read it please take a few moments to review it on Amazon or elsewhere – it really does help, and as I am finishing up writing St Cybi’s Well the feedback is most welcome.

Because, yeah:

An excellent read by an old and dear friend: There’s an App for That: Cancer in the Modern Age

* * *

And another excellent read, all in all. But this paragraph is so painfully true:

“Writing is a strange and solitary activity. There are dispiriting times when you start working on the first few pages of a novel. Every day, you have the feeling you are on the wrong track. This creates a strong urge to go back and follow a different path. It is important not to give in to this urge, but to keep going. It is a little like driving a car at night, in winter, on ice, with zero visibility. You have no choice, you cannot go into reverse, you must keep going forward while telling yourself that all will be well when the road becomes more stable and the fog lifts.”

Of course, reading is always better for you: Brain function ‘boosted for days after reading a novel’

See? I’m actually making you SMARTER! Keep that in mind when you write a review, will ya?

And that’s enough for now. I need to get back to my “strange and solitary activity”.

Duuun dun duuun dun …*

I can’t help but hear the Jaws theme when I read something like this:

But this is all great news for astronomers: KKs 3 is a relic, so isolated and old it probably hasn’t changed much in a long, long time. Studying it is like having a time machine to study the ancient Universe. And we think that, billions of years ago, collisions between small galaxies like KKs 3 are what built up much larger galaxies. We know that the Milky Way is currently eating a few other small galaxies, so we can study those events and compare them to what we see in KKs 3 to learn more about how this process may have occurred so far in the past.

There’s a thought for you — galaxies as living entities, with the big ones as predators hunting smaller ones …

400 downloads of Communion of Dreams so far this weekend! The Kindle edition remains free through today, if you know someone who might like to have it.
