OK, this project from NASA is pretty damned cool:
This is not a special effects scene from a science fiction movie: This is real. It’s a video showing the Morpheus Project prototype vertical takeoff and lander doing its thing at Kennedy Space Center in Florida on Mar. 5, 2014 (and you absolutely want to make it full screen and turn the sound up to get the full effect).
Furthermore, it’s a completely autonomous system — onboard software — doing the take-off and landing.

From Chapter 3 of Communion of Dreams:
Apparent Gravity was the third major application of the theories set forth in Hawking’s Conundrum, the great opus of
Stephen Hawking which was not published until after his death in the earlier part of the century. He hadn’t released the work because evidently even he couldn’t really believe that it made any sense. It was, essentially, both too simple and too complex. And since he had died just shortly before the Fire-flu, with the chaos that brought, there had been a lag in his theory being fully understood and starting to be applied.
But it did account for all the established data, including much of the stuff that seemed valid but didn’t fit inside the previous paradigms. Using his theories, scientists and engineers learned that the structure of space itself could be manipulated.
Of course, that is the reality of St. Cybi’s Well, not our own. In our reality, there’s been no fire-flu (at least yet), Stephen Hawking is still alive, and the laws of physics are still the same.
Black holes are in crisis. Well, not them, but the people who think about them, theoretical physicists who try to understand the relationship between the two pillars of modern physics, general relativity and quantum physics. Judging from the current discussions, one of the two must go, at least in their present formulation. On January 22nd, Stephen Hawking posted a paper where he bluntly stated that black holes, in the sense of being objects that can trap light and everything else indefinitely, are no more. And that’s a big deal.
Sometimes I wonder what reality I am actually plugged into, since it seems that I keep getting leaks from the other one.

Next Wednesday is the 50th anniversary of the release of the classic film “Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb.” It’s long been one of my favorite movies, even as a kid. Yeah, I was a strange kid. Don’t act like you’re surprised.
A decade after the release of “Strangelove,” the Soviet Union began work on the Perimeter system—-a network of sensors and computers that could allow junior military officials to launch missiles without oversight from the Soviet leadership. Perhaps nobody at the Kremlin had seen the film. Completed in 1985, the system was known as the Dead Hand. Once it was activated, Perimeter would order the launch of long-range missiles at the United States if it detected nuclear detonations on Soviet soil and Soviet leaders couldn’t be reached. Like the Doomsday Machine in “Strangelove,” Perimeter was kept secret from the United States; its existence was not revealed until years after the Cold War ended.
“Detecting nuclear detonations” … hmm, where have I heard that phrase recently? Oh, yeah:
On the second day of 2014, a small asteroid blew up high in Earth’s atmosphere. It was relatively harmless—the rock was only a couple of meters across, far too small to hit the ground or do any real damage—and it disintegrated over the Atlantic Ocean anyway.
What’s cool is that now we know for sure this is the case: Infrasound detectors designed to listen for nuclear bomb detonations actually heard the explosion from the impact and were able to pinpoint the location of the event to a few hundred kilometers east off the coast of Venezuela.
NASA put together a nice informative video explaining it:
Gee, it sure is a good thing nothing like that has ever hit the territory of the old USSR … er, oops.
And now that I’ve given you a nice dose of fright, let me make it up to you with a reminder that you can download Communion of Dreams (which has it all … game theory, nuclear exchanges, and more than a little of my old strangeness) for free today and tomorrow!
*The title of one of Herman Kahn‘s books about nuclear war/deterrence, and where I think I was first exposed to the concepts behind game theory. I’ve got Schlosser’s book Command and Control on my to-read list when the Kindle price comes down a bit.

This is a really interesting idea: that fundamental thermodynamic forces lead very naturally to the the beginning and evolution of life. From the start of the article:
Why does life exist?
Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.”
From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.
It’s important to note that this is not in any way in conflict with current understanding of evolution — rather, as the article says: “England’s theory is meant to underlie, rather than replace, Darwin’s theory of evolution by natural selection, which provides a powerful description of life at the level of genes and populations.”
Take a few minutes to read the article; it’s well written and non-technical but assumes a basic scientific understanding of both evolution and thermodynamics.
And if proven true, implies that the universe should be full of biological life as a manifestation of basic physical processes.
*Very* interesting, indeed.

The following post contains spoilers regarding Communion of Dreams. In fact, it contains such spoilers that I’m going to put it after a break, so that you have to actually scroll down to see it. For anyone who hasn’t read Communion of Dreams, you’ve been warned.
I’ve been asked many times what comes after the end of Communion of Dreams. The answer to that is tied up with questions of just exactly why there is a “barrier” around our solar system, which has been hiding any and all indications of extra-terrestrial life/intelligence/civilization from us.
Let’s just say that I have my own … ideas … on the subject. Which I may or may not someday explore/make public. We’ll see.
But of the many possibilities, this is one very viable explanation. And it’s pretty well done:

Another item that would likely help get this book moving is a different cover. I understand the imagery now that I’ve read the book, but definitely think it will keep hard-core sci-fi fans from buying a copy (and people do judge books by their covers).
Like I said, every so often a comment to this effect will pop up in a review. And I don’t spend much time thinking about it (and I’m not going to change the cover image at this point), but now and then I wonder just what kind of a cover would appeal to ‘hard-core sci-fi fans’ and still make any kind of sense in relation to the story. Maybe some nice images of Saturn or Titan from the Cassini mission? A depiction of some of the spacecraft (which aren’t described in much detail in the book), or perhaps the Titan Prime space station? Go with a charming post-apocalyptic montage of ruined cities and microphotographs of viruses? To me, none of these would fairly represent the story, and to a certain extent would unnecessarily limit the appeal to only ‘hard-core sci-fi fans’.
But I’m curious what others think. So feel free to post a comment here or over on FB. Over even on Amazon, as a comment on an extant review or in new review of your own. In a week or so I’ll go through all the various comments I can find, and pick someone to get a jar of my latest hot sauce (or something else if they don’t want that).
PS: there’s another new short review up on Amazon you might want to take a look at as well.

Some quick links, none of which really warrant a full blog post.
Wanna be a black-hole hunter? Sure you do! The Galaxy Zoo folks have just launched a new project you should check out:
Black holes are found at the center of most, if not all, galaxies. The bigger the galaxy, the bigger the black hole and the more sensational the effect it can have on the host galaxy. These supermassive black holes drag in nearby material, growing to billions of times the mass of our sun and occasionally producing spectacular jets of material traveling nearly as fast as the speed of light. These jets often can’t be detected in visible light, but are seen using radio telescopes. Astronomers need your help to find these jets and match them to the galaxy that hosts them.
We live in the glorious future, where beer concentrate is a real, practical thing!
For fans of craft beer, enjoying a decent brew while hiking or camping away from the car usually involves lugging around heavy cans of beer, which can turn a lovely trek into a grueling slog through the woods.
But now the folks at Pat’s Backcountry Beverages have created a solution – their new Brew Concentrates come in featherweight 50ml packets and can be reconstituted with carbonated water (courtesy of their trail-ready 16-ounce carbonator bottle).
Well, actually, the past wasn’t so bad in some ways, either …
When you think of illicit substances that are shipped in brick form, wine probably doesn’t come to mind first. And no, boxed wine doesn’t count. During Prohibition, however, drinkers got around laws that banned alcohol by dissolving bricks of grape concentrate in water and fermenting them into wine.
Of course, conscientious makers of grape bricks didn’t want to contribute to bad behavior, and responsibly warned buyers that, “After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.” The makers of the Vino Sano Grape Brick even dutifully indicated what flavors one’s careless handling of grape bricks would result in: burgundy, sherry, port, claret, riesling, etc.
