One of the things which has always really interested me is how the perception/experience of time is so very … plastic. Partly that is because of curiosity about the nature of time itself, but partly it is also because the experience of time is so highly variable between species* and even individuals. Personally, I have been through experiences when subjective time dilation completely changed my perception of reality. There are some hints/references about this interest in Communion of Dreams, and there will be others in St Cybi’s Well, but I have yet to really get into dealing with the notion directly.
Anyway, that’s why things like this always fascinate me:

For those who don’t know, one of my other interests is handgun ballistics research. Specifically, in regards to how barrel length effects bullet velocity for different cartridges and loadings. Even if you don’t like guns, the physics behind ballistic performance can be very interesting.
And here’s a wonderfully graphic image showing those physical forces:
Text from the source to go with this image (site is Finnish, and English is not the author’s first language):
Let’s talk a bit about .44 Magnum cartridge. Despite of being very close to diameter of .45ACP the .44Mag is totally different beast. Average .45ACP round generates ~650J of hit energy while .44Mag makes easily 1600J and can be pushed much more beyond that. This specific gun however cannot utilize all potential of .44 Magnum cartridge because of very short barrel. It simply cannot burn all powder. As you can see there is huge cone shaped spray of unburnt stuff flying in the air. With longer barrel show would be different.
Ok, you may have noticed the flames. They are something we haven’t seen before. Especially when you look picture below and huge left side flame in it. Interesting thing is that major amount of the flame is escaping between cylinder and barrel. That short barrel seems to puff bullet our so fast that powder mass just flies out unignited.
The site is filled with a bunch of great high-speed camera images of guns being fired. And it also has something else which is new to me: ‘natural stereoscopic’ images of guns being fired. Like this one:
Now, what do I mean ‘natural stereoscopic’ images? Well, this is pretty cool itself. Here’s a reference link & explanation from the Kuulapaa site:
Each stereo view consists of two images, one for each eye. Free viewing is the technique that will allow you to direct each of these images separately and simultaneously into each eye. Once that happens, you are said to have “fused” the pair of images into a stereo view.
At the bottom of this page a stereo pair of images is loading with which you can practice. All the stereo pairs shown on this site are in the “cross-eyed” format (my apologies to all the “wall-eyed” people). That means that the first (leftmost) image is for your right eye and the right image is for your left eye.
There are then a series of practice image to show what he means and give you a chance to develop this viewing skill. It works fairly well for me, but does tire my eye muscles fairly quickly. Give it a try and see how you do.

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.

This is a really cool application of imaging technology: a massed ball of high-quality digital cameras which can capture a gigapixel panorama in one instant. And the neat thing is that one of the main people behind this understands that while he can imagine some uses for such a camera system, there will come applications which he cannot now envision. From the NPR story:
His team has photographed Duke University football games, for example, that let you zoom in and see the ball in the air, plus the faces of all the players in the field, and the faces of all the fans in the stands.
“I can’t imagine … how people are going to use these things,” Brady says, “and, of course, since I’m an instrument builder, that’s the real interest. Because I’m sure photographers will use it in ways that I haven’t even thought of.”
Nice to see that awareness of shifting reality.

McBAINE — Five years ago, when the father-son duo of Bill and Kyle Spradley teamed up to give the state champion bur oak at McBaine some much-needed attention, they were joined by a handful of people.
Yesterday, more than 40 people gave the majestic tree a hefty dose of TLC. The gathering included representatives of 10 organizations and businesses from across the state — most of them arborists or rural electric linemen experienced in tree-trimming and pruning.
That goes to show how much people care about this tree,” said Kyle Spradley, a senior information specialist at the University of Missouri College of Agriculture, Food and Natural Resources. Spradley also has his own photography business, and many of his photos feature the McBaine bur oak.
I’ve written about the tree previously, for the very good reason that it is the image used on the cover of Communion of Dreams (and so, at the top of this blog). And I’m glad to see this sort of effort to help care for the tree, and preserve it for future generations. Seriously, if you haven’t ever seen it in person, and you find yourself in the area, it is worth a visit.
