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.

… said no one ever about Communion of Dreams. Oh, it’s got a buttload of positive reviews, but it’s a ‘serious’ book in the sense of being about Big Questions of Humanity’s Role in the Universe and all that . And, truth be told, so is St. Cybi’s Well (at least I hope so).
But as I’m starting to see the prospect of finishing SCW sometime in the next months, and perhaps because I’ve been in a bit of a funk lately, I’m kinda in the mood to write something which isn’t Oh So Serious. Something light, fun, perhaps even popular. (Gawds, what a concept.) Maybe something like The Princess Bride, but recast in feudal Japan. Or Star Wars redone as the Western it is at heart.
And speaking of which, guess what I found:
Bob A. Ford
The typical wild west bounty hunter who sells his services to bring in anyone with a price on their head. His quiet demeanor and lighting reflexes makes him one of the most dangerous men on the prairie.
There’s a whole series of these set in different periods/worlds, and they’re all completely delightful.
And we need more delight in our lives. All of us.
So, something to think about.
Oh, PS: thanks to one and all who downloaded CoD during the weekend promotion. Not huge numbers, but not bad: about 550 downloads around the world. Interestingly, the Amazon portal in Germany was the second-highest number of downloads (second to the US, of course), with a couple dozen. First time that’s happened, and that’s a bigger total for there than ever before to the best of my recollection. No idea why.

Most of the book conservation work I do is pretty nondescript, just workmanlike. After all, the intent isn’t to draw attention to my work, but to preserve as much of the original character and structure of the book as I can.
But now and again I get to do some ‘pretty’. And it’s nice to come across those again later, particularly when for whatever reason I’m feeling a little down. It’s a pleasant boost to my self esteem. Such it was yesterday when I was browsing through the Adopt-a-book program at MU’s Special Collections, and saw this entry:
Adopt-a-Book > Book Detail
Author: Cicero, Marcus Tullius. Published: Venetiis : Apud Aldum et Andream Socerum, 1512
Description: Take apart and resew, saving the label where possible. New leather binding
Condition / repair needed: This codex was printed by the legendary Aldine Press. It was printed during the life of Aldus Manutius, the founder of the press. The most famous dolphin and anchor printer’s mark is seen on the title page.
Thank You to Donor:J. Schweitzer, R. Drake and M. Correale
I’ll explain later why it was that I was browsing the site (it was a good reason, but I don’t want to get into it just yet).
As for why I was feeling down … No special reason, as I mentioned yesterday. Getting over the touch of the flu I had early in the week. A touch of the winter blahs. The mild feeling that I get in the middle of any project that I have bitten off more than I can chew and that I’m going to fail spectacularly.
So it’s nice to see tangible evidence that I actually can do something well.

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.

I am staggered by this thing: a 35-minute “paraphrasing” of Ridley Scott’s Blade Runner from 12,597 animated watercolor paintings. It’s beautiful and insane—who would do this? A really big Blade Runner fan, I guess.
That fan is Swedish artist Anders Ramsell, who hand-painted each of the thousands of 1.5 by 3 cm paintings that make up the film, then synced them up to audio from the movie. The results are moody, and dreamily gorgeous.
Judge for yourself:
For me, this presentation/interpretation works, because it fits so perfectly with the theme and style of the movie. Very impressive.

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.

Via Phil Plait, had to share this:
Saturn, obviously. But from a new perspective, as Plait explains:
But dominating this jaw-dropping scene are Saturn’s magnificent rings, seen here far more circular than usual. Cassini’s mission has been to observe Saturn and its moons, which means it tends to stay near the planet’s equator. But now scientists are playing with the orbit more, to do more interesting science. The spacecraft is swinging well out of the equatorial plane, so here we see the rings at a much steeper angle, and they are less affected by perspective.
And here’s the link to the full-size image, which is definitely worth a look.
