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. The first major application led to practical, safe, and efficient fusion power. Rather than forcing high-energy particles together, the forces keeping them apart were just removed. Or, more accurately, the manifestation of space between them was inverted. It took very little energy, was easy to control, but only worked in a very localized fashion
Their latest offering is something called “shape dynamics.” (If you’ve never heard of shape dynamics, that’s OK—neither have most physicists.) It could, of course, be a dead end, as most bold new ideas in physics are. Or it could be the next great revolution in our conception of the cosmos. Its supporters describe it as a new way of looking at gravity, although it could end up being quite a bit more than that. It appears to give a radical new picture of space and time—and of black holes in particular. It could even alter our view of what’s “real” in the universe.
* * *
In most situations, shape dynamics predicts what Einstein’s theory predicts. “For the vast majority of physical situations, the theories are equivalent,” Gryb says. In other words, the two frameworks are almost identical—but not quite.
Imagine dividing space-time up into billions upon billions of little patches. Within each patch, shape dynamics and general relativity tell the same story, Gryb says. But glue them all together, and a new kind of structure can emerge. For a concrete example of how this can happen, think of pulling together the two ends of a long, narrow strip of paper: Do it the usual way, and you get a loop; do it with a twist and you get a Möbius strip. “If you glue all the regions together to form a kind of global picture of space and time, then that global picture might actually be different.” So while shape dynamics may recreate Einstein’s theory on a small scale, the big-picture view of space and time may be novel.
Another prediction come true?
Not really — there were intimations of this theory when I was working on CoD, and it is a *very* long way from being accepted as valid, as the Nova article discusses.
But still …

New review up at Amazon:
New Age Sci-Fi, October 15, 2015By A ReaderThis review is from: Communion of Dreams (Kindle Edition)I borrowed this book from the Prime lending library as I was in the mood for a good old sci-fi first contact story and the books description lead me to believe that’s what it was. The first part of the book was exactly that. But then it shifted and did become more of a spiritual, new age-y, story about aura’s, healing hands, meditative states, etc. that just happened to take place on Titan. That’s not a bad thing, but it just wasn’t what I was in the mood to read at the moment. I should have suspected as much as the cover art and title depict nothing alien/space related, my bad. The story was interesting and kept my attention, the writing was good, the ideas presented interesting. But heads-up, if you’re in the mood for aliens, this might not be the book to read.
Well, I can’t really disagree, but … huh.
And there’s also a new review of Her Final Year you might enjoy.
Have thoughts about either one? Comment here, there, or maybe even write your own review!

Except fish. Fish don’t like books. At least as far as I know.

The biggest reason to build big ships may be the promise of electricity generation. The most interesting innovations in naval technology involve sensors, unmanned technology, lasers, and railguns, most of which are power intensive. Larger ships can generate more power, increasing not only their lethality (rail guns, sensors) but also their survivability (anti-missile lasers, defensive sensor technologies, close-defense systems).
Unmanned technology. Lasers. Railguns.
Tell me that ain’t living in a science fiction future.

Here’s a great example of why you may want to:
on July 8, 2015OK
That’s the complete review. Which would be fine, since if someone thinks the book isn’t that great, perhaps that’s all they would feel like saying.
But I was curious about her other rankings, so went to check. You can too. Just click the name. And you’ll see that yesterday Dianna reviewed and rated 74 different items on Amazon. All except one were given three stars. And all were reviewed with just “OK”.
I don’t mind negative reviews. I don’t mind “meh” reviews. Both provide valuable feedback. But ones like this are hard to take seriously.

I wrote this nine years ago, and posted it to this blog seven years ago. It seemed like a good time to repost it.
Thoughts on This Day
One birthday, when I was nine or ten, I woke with anticipation of the presents I would receive. Still in my pajamas I rushed into the kitchen where my parents were having coffee, expecting to get the loot which was rightfully mine. My father happily handed over a small, wrapped box. I opened it eagerly, to find a little American flag on a wooden stick. My father said that since my birthday was July 4th, he thought I would appreciate the gift.
Horror-struck first at not getting anything better, then a moment later at my own greed, I guiltily told my parents that I thought it was a fine gift.
After a moment, of course, my folks brought out my real presents, and there was a fair amount of good-natured teasing and laughing about the little trick they had played on me.
That was almost 40 years ago, and I can no longer tell you what presents I received that day. But the lesson in expectations and perspective my dad taught me that morning always remained with me. My dad had been a Marine, fought in Korea, and was a deeply patriotic cop who was killed while on duty a couple of years after that birthday. I have no idea what happened to that little flag on a stick, but I do still have the flag taken from my father’s coffin, carefully and perfectly folded at the graveside when we buried him.
I’ve never looked at the American flag without remembering what a fine gift it really is and, as so many others have written, what it represents in terms of sacrifice. I love my country, as any Firecracker Baby is probably destined to do. You just can’t ignore all that early training of patriotism, fireworks, and presents all tied up together.
But that doesn’t mean that I am blinded by patriotism. As I’ve matured and gained life experience, I’ve learned many other lessons. Lessons about tempering expectations, living with occasional disappointment, accepting that things don’t always work out the way you plan no matter how hard you work, how good your intentions, or how deserving you are. Still, you learn, grow, and do the best you can. This, it seems, is also the story of America. I believe we are an exceptional people, holding great potential, with our best years still to come. But nothing is guaranteed. We must honestly, and sometimes painfully, confront our failures, learn from them, and move on. The original founders of our country were brilliant, but flawed as all humans are flawed. Some of their errors led directly to the Civil War, that great bloody second revolution of the human spirit. That they made mistakes does not negate their greatness; rather, it shows us our potential even though we are not perfect. They knew, as we should know, that only we are responsible for our self-determination. Not a king, not a God, not a ruling political class. Us.
Today we’ve been gifted with a small box with a flag inside. A token of our history. Let us not take it for granted. Let us not think that the thing itself is more important than what it represents. Let us look on it and declare our own responsibility, our own self-determination.
Happy Independence Day.

From the beginning of Chapter 6:
There was just one other person in the room, standing at the side of the holo platform, hands dancing over a control board only he could see.
* * *
Jon looked to the dance Ng’s hands played in the air. “About ready?”
Ng said nothing, but just his fingers tapped a command in the air. Instantly, there appeared an image above the holo projector. It was the artifact, pretty much exactly as Jon remembered it from the first meeting a week ago.
There are many such passages in Communion of Dreams, just part of the augmented reality technology which exists at the time of the book. The basic explanation is that the user is wearing contact lenses which allow one to see a virtual reality overlay on the real world, and then within that overlay you can manipulate virtual objects/controls thanks to hand-tracking. When I wrote the book I figured that such technology would be available eventually …
… and here it is, even sooner than I expected:
* * *
The company’s lab for advanced projects showed off new technology on Friday that lets users move their fingers in the air to control objects in the virtual world.
It’s called Project Soli, and it uses radar waves to detect precise finger movements or finger “micromotions.”
The result is something that looks like it’s from a science-fiction movie such as Minority Report or Her, in which characters manipulated virtual objects by gracefully moving their hands or fingers in the air.
