The ballistics testing is finished. Well, sort of. As I mentioned yesterday, the primary goal was to get through the barrel-chopping tests, get all the data from that, and to worry about the ‘real world’ guns sometime later. And we accomplished that. Early on, as we were cruising along, it looked like we might wrap up really early, perhaps mid-day.
Of course, it couldn’t possibly work out that way.
Just as we were down into the 3″ barrel lengths, disaster struck: the mounting rail for the laser busted loose. And not just a little bit – the mounting screws stripped out, and there was no way to fix it short of machining in new threads on the receiver. That’s not the sort of thing you can do out in the field.
Remember I said this, yesterday:
We have four more ‘flights’ of ammo to test today (we did six yesterday), going from barrel lengths of 5″ down to 2″. When we get to the point where the length of the barrel is less the the housing of the receiver (the pistol), things get tricky, but the aiming laser will help a lot.
Um, oops.
And of course, the thing didn’t fail all at once. We got to go through that wonderful process of noticing the impending disaster and trying to cope with it, using this or that strategy, each attempt sorta working for a little while before failing. That took about two hours. And just when we thought we had it secured, a shot with one of the powerful calibers (I think it was a .45 Colt) sent the thing flying in recoil.
Steve, who probably has the most experience as a shooter of any of us, figured that he might as well see if he could shoot the pistol, sans laser. And sans any other sort of sight. Even without the benefit of a barrel, since once we got to that point, the short little bits of barrel were *down inside* the housing of the Thompson/Center Encore pistol (look down to ‘Number 1842’ to get an idea of what just the housing looks like – it’s the part without a barrel or anything attached, off on the left side).
This, needless to say, was going to be a difficult accomplishment, for just a few shots. Doing it for a couple hundred data points (shots were only considered “good” if we got comparable readings from both chronographs), using always-changing types of ammo and different calibers, almost impossible.
But Steve did it. We decided that his secret ‘super power’ is the ability to shoot amazingly well in really dumb situations.
So, we got it done. Got all the data we considered critical for the project. Packed up the stuff we didn’t want stolen, and what needed to go back to Iowa with Jim K, came home. I’ll get the rest of the set up (tent, tables, et cetera) today. And Steve and I will go out sometime in the next week or so and do the ‘real world’ testing, using guns on the market with the same ammo as for the test, which will give us some benchmark comparisons to relate to the ‘ideal’ data.
Big project. The better part of $7,000 worth of ammo, and $5,000 for the custom barrels. Add in another three or four thousand for incidental stuff (lasers, chronographs, generator, chop saw, and so forth). Maybe 250 man-hours of labor for the actual testing component. And we’re still a long ways from being done. We still need to do all the data entry, design a website, write everything up so that all the information – warts, glitches, and errors – is available freely to anyone who is interested in seeing hard data about what the correlation is between barrel length and ammo performance. I’m guessing we still have several weeks before we can say that it is done.
But one hell of a big part of it is accomplished. And that feels really good.

This is going to be fairly brief – I still have a lot to do this morning and only about an hour to do it.
You know how you feel when you first start a new job, with the uncertainty and intense learning curve? OK, keep that in mind. Now, you know how you feel after a good workout, doing exercise or a bunch of yardwork? Add that in. How about that great feeling of accomplishment, yet exhaustion that comes with finishing a big and difficult project? Add that, too. And lastly, if you are an intensely introverted person, used to being alone about 85% of the time, but switch around to being with people constantly for a week? (Extroverts, I think you’d get a similar feeling by being stranded on a desert island for a week, with no human contact to recharge you.) That’s how I feel. All of it together.
In other words: “Damn, I’m beat.”
The ballistics testing project continues to go very, very well. With a little luck we should wrap it up today. We’ve had a variety of minor glitches, each of which has required some good ol’ Yankee Ingenuity to resolve, but nothing major. The new ‘armour’ protecting the replacement chronographs works – yes, one of us managed to bounce a round right off the top of it (likely would have missed the chronos, but still . . .). The new chronos themselves are a great improvement over what we had been using. The laser has had some problems – good thing we ordered in overnight three additional ones on Thursday, as back-ups. And now that we’ve gotten down to the ‘good parts’ (barrel lengths typical for most defensive handguns), we’re both really excited and really getting pummeled by the effects of the blast of repeated discharges in close quarters.
But we’re coping. Using the box for the portable generator, combined with additional layers of cardboard, we’ve created a ‘blast shield’ to mitigate the worst of the shock wave. All the recording process has gotten smoothed out by experience. The chopping of the barrels continues to be simple. It’s going really, really well. We have four more ‘flights’ of ammo to test today (we did six yesterday), going from barrel lengths of 5″ down to 2″. When we get to the point where the length of the barrel is less the the housing of the receiver (the pistol), things get tricky, but the aiming laser will help a lot. Whether we get to doing tests of ‘real world’ guns with the same ammo today is not too critical, since we can do those on another day with a whole lot less equipment (no need for the chop saw, generator, et cetera). So we should finish the main part of the test today, follow up with the rest later.
Well, gotta run.

Ever see what happens to modern electronics when you shoot them with large caliber handguns?
Wait . . . I’m getting ahead of myself.
* * * * * * *
As noted previously, I’ve been busy the last few days getting things ready to start the next round of ballistics testing. Round one was about three weeks ago, and in addition to getting a lot of good data about three of the 13 calibers we’re doing the research on, we also learned a great deal about the testing platform and procedures. Because of that amount of learning, when the three of us got together this week before setting everything up on Wednesday, we decided that we would go ahead and push this weekend to do all the remaining testing.
As a friend said in an email Wednesday night: “Whoa.”
Yeah, because that is 10 more calibers (eight barrels, since the .38 special and .357 magnum bullets use one barrel, and so does the .44 special and .44 magnum). And over 5,000 rounds of ammo.
We’re fortunate in that all three of us (me, Jim K and Steve) are all in situations where we can set aside our work demands for a time and devote our attention to doing this. And in looking at the remaining barrel/ammo combinations, it was clear that there would be some efficiency in doing things all at once – a number of the somewhat more unusual calibers have only two or three types of ammo, meaning that we’d be spending more time swapping out the barrels and chopping them than actually shooting and recording data. So there would be a benefit in getting all those calibers done, then move on to the several calibers where we had a lot of different ammo to test while the other barrels were chopped and prepped (de-burring and modest recrowning to get good consistent results).
And that’s what we did yesterday – dove in head first, in spite of very uncooperative weather (lots of rain and temps in the 40s). Our set-up keeps us out of the wet (we’re using a fair-sized cabin tent for our work area, with the chronographs outside under a protective tarp) but the damp chill still takes a lot of energy out of you. The changes we made to the shooting platform – the addition of an inexpensive target laser – meant that you essentially didn’t need to take the time to aim the thing (once we had it zeroed in), all you had to do was control it with the more powerful calibers.
And before we stopped early in the day, we had gotten to the same point with these remaining 10 calibers as we got on the first day of the previous round of testing with just three calibers.
Now, why did we stop early, if things were going so well?
Wasn’t due to the weather. Not unless you consider a .45 caliber bullet as rain.
What happened was this: one of us (who shall for now remain nameless, until I can spend more time to write up the saga appropriately) was in the middle of shooting the second most powerful of the calibers we’re testing, and didn’t manage to control the gun completely when he fired the round. And it went right through both chronographs. Perfectly.
We use two chronographs, lined up one in front of the other, to be sure we’re getting good data. He hit the first one right dead center, a little high from the middle. Like a perfect shot in a movie, hitting the bad guy right between the eyes. The large bullet punched through the display, destroyed the electronics, and shattered the back of the chrono – then entered the front sensor of the second chrono, exiting out the bottom rear sensor as well.
It was spectacular. A perfect shot. I have pix I’ll be posting later.
But it meant we were done for the day. No chronographs, no way to measure the velocity of the bullets.
But such things are available here, and we’ll pick up a couple more units this morning. And we’ll be getting the kind which have a remote readout – meaning that it’s just the sensors in the line of fire, the electronics on our shooting bench. Meaning that we can place some protective armor plates in front of the sensors to prevent this from happening again.
Meaning that we’ll just have to find a new and improved way of screwing up. 🙂
More when I get the chance.

. . . in 2052 Darnell Sidwell finds the alien artifact on Titan.
Yup, the clues in the text are clear – the artifact is first discovered on April Fools Day, though that is never explicitly stated.
Why did I do this? For my own amusement, mostly. I appreciate a good April Fools joke – one that plays on someone’s expectations and gullibility, one like you’ll frequently catch on NPR that just might be possible. Given the way the discovery plays out in the story, I thought it a good place to start.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Couple of brief notes: downloads of the text of Communion of Dreams are now over 8,300, and almost 100 people have downloaded the first chapter of the mp3 files (with all the different sections of chapters in those files, and no comprehensive download file to track easily, I’m mostly going to keep tally on the first chapter for simplicity.)
We’ll be starting the next round of ballistics testing tomorrow, so my posting schedule might be kind of erratic through the weekend.
Watch out for April Fools!

You may recall the 2001 effort to get people to register their religion as “Jedi”. Like some of the other silliness at the turn of the century, it was mostly harmless.
Well, it seems that earlier this year a couple of brothers in Wales decided to take it a step further:
Force strong for new Jedi church
Two Star Wars-loving brothers planning a Jedi church hope it will be much nearer than a galaxy far, far away.
Barney and Daniel Jones want fellow devotees to be able to join them close to their home on Anglesey.
Barney, 26 – or Master Jonba Hehol – and Daniel, 21 – Master Morda Hehol – head the UK Church of the Jedi, in honour of the film’s good knights.
And you gotta give the guys credit – they know how to keep their name in the news:
Anglesey Jedi Church announces plans for Moon colony
AN ORDER of Holyhead Jedis has begun steps to colonise the moon.
The UK Church of the Jedi, run by brothers Daniel and Barney Jones, of Holyhead, are setting up a micro nation on the moon.
They have bought a plot of land on the moon and the order plan to have a capital city and appoint worthy Jedi to positions such as Head of Galactic Affairs and Country Ambassador.
Alas, with notoriety also comes occasional tragedy:
Star Wars comes to Holyhead as Darth Vader strikes back in Jedi’s back garden
A Star Wars fan got closer to his idols than he would perhaps have liked when he was attacked in his garden by Darth Vader.
Jedi Master Jonba Hehol – known to family and friends as Barney Jones, 36, of Holyhead – was giving a TV interview in his back garden for a documentary when a man, dressed in a black bin-bag and wearing Darth Vader’s trademark shiny black helmet, leapt over his garden fence.
Wielding a metal crutch – his lightsaber presumably being in for repairs – the Sith Lord proceeded to lay about his opponent, whose Jedi powers proved inadequate for the task of defending himself.
After besting Master Hehol in single combat, Vader, who The Sun reports was under the influence of alcohol, went on to assault the camera crew and a hairdresser.
It’s always something.

[This post contains mild spoilers about Communion of Dreams, particularly chapter 5.]
As I’ve been doing some conservation work this morning, I’ve been listening again to the audio version of Communion, done by Scot Wilcox of OwnMade AudioBooks, and discussed previously. I just enjoy hearing his interpretation.
Anyway, at the end of chapter five, as the first team of researchers is about halfway to Titan to investigate the alien artifact which has been discovered there, the protagonist has an odd dream which is described in some detail. In the dream Jon (the protagonist) crosses a bridge, and there’s lots of symbolism which is important for how the rest of the book unfolds. For this reason, I worked fairly hard to get the description just right. Scot’s reading of the passage is great, and really brought that scene to life for me.
Which is fairly easy, because it is based on a real scene – a real bridge: this bridge on the campus of the University of Iowa, which I crossed often while in graduate school at the Iowa Center for the Book. And the fun thing about that bridge – which I used for my own purposes in the description in the novel – is that because of the way it is built, it has a kind of spring to it as you walk across.
I enjoy knowing from whence artists and authors draw their inspiration and imagery, and thought I would share this on the off chance that someone else might be curious . (If anyone has better images of the bridge, feel free to post them/a link in comments – those were the best I could find with a quick search, but they are very dated.)

OK, just in case you haven’t seen this over at PZ’s or elsewhere, here’s a hilarious and brilliantly done satire:
It takes some deconstructing, but the consensus is that it is indeed pro-science/skepticism.
UPDATE: Here are the lyrics, and here is a brief bit on the ‘cast’ – kudos to both authors!

There’s a good piece by Seth Shostak over at Space.com about the possible motivations an extra-terrestrial race might have for visiting our pale blue dot. (Shostak is one of the principals of the SETI Institute, and knows whereof he speaks when he addresses these kinds of issues.) First, he dismisses the usual SF plot devices of an alien race wanting our turf, our resources, or even our bodies:
Taking our cue from Tinseltown, I note that most cineplex sentients come to Earth either to solve some sort of ugly reproductive crisis or simply to take over the planet. The former doesn’t make any sense whatsoever. You can’t breed with creatures at the zoo, despite the fact that most of the base pairs in the inmates’ DNA are identical to yours (note that this is a biological incompatibility, and not just zoo regulations). The aliens, needless to say, will have a different biochemistry, and probably no DNA at all. Forget, if you can, the breeding experiments.
Taking over the planet would only make sense if there were something really special about our world. The best guess of the exoplanet specialists is that the number of Earth-size planets in our galaxy exceeds tens of billions. That doesn’t sound like our hunk of real estate is terribly privileged.
They won’t come here to mine our minerals, either. The entire universe is built of the same stuff, and while the solar system has a higher percentage of heavy elements than found in many stellar realms, it turns out that this is precisely the condition that seems to foster planet formation. In other words, ET’s own solar system will be similarly blessed with these useful materials. So why would they come here and incur multi-light-year transport charges?
Why, indeed? These various issues are ones which are discussed in the course of speculation about the alien artifact discovered in Communion of Dreams. And while I never actually reveal the motivations that aliens might have for having left the artifact on Titan in my novel, I do have thoughts on the subject (which might come out in a future sequel to Communion.)
Be that as it may, Shostak does go on to make a pretty good argument that if indeed there are a large number of technological civilizations out there, that they may just not consider us worth the trouble of contacting/visiting. Again, from the article:
Then again, there’s that last point: they just want to learn more about us. Well, perhaps so. Maybe that’s really what’s interesting about Homo sapiens. Not grabbing our habitat, saving our souls (or our environment), or subverting our industrial output — but assaying our culture. I’m willing to consider that even very advanced beings might find our culture mildly worthy of study.
Keep in mind that if they’re near enough to find us, that implies that there are many, many galactic societies (otherwise the distances between any two of them will be enormous). If there are lots of them, then we’re just another entry in a big book. Once again, not all that special. Kind of like another weird fish found in the Atlantic. I don’t expect mammoth expeditions to be sent our way.
It is a good point. I would counter, however, that we have seen plenty of evidence in our own history of people going to enormous trouble to bother to learn about seemingly trivial things. One only has to look at the difficulties encountered in sea-faring during the time of the great naturalists – people were willing to go to great expense, to risk great hardship and a fair chance of death just to add another entry into the botanical texts or to discover a new species. Even today we mount insanely expensive expeditions into the deep ocean just to expand our knowledge.
We have no evidence of extra-terrestrial life, let alone advance civilizations. Yet I think that you can make a fair case that any space-faring race which may exist must have some degree of curiosity – and that curiosity may alone be reason enough to come check out the new kids on the block, whatever the hurdles or cost.

Gah. I am either having a relapse of the very stubborn flu that had me laid low last month, or am fighting some new bug with similar (yet still considerably less severe) symptoms. This is highly annoying.
So, I’m about to go take a nap. But first a couple of quick notes, and then a bit from Phil Plait’s blog about a recent discovery that is very exciting.
Note one: downloads of the .pdf of Communion of Dreams have crossed 8,200 and downloads of the audio version continue to climb as well. That’s exciting.
Note two: heard nothing yet from the agent I mentioned contacting the other day. No surprise – I expect that it will take a month or so to hear from them. But I needed something else to note.
Now, about the news from space . . .
I have written previously about the Cassini probe’s 10 year mission to Saturn, and how there have been a lot of great images and information coming back to scientists about that planet and its moons. Information that helps to confirm what we knew when I was first writing Communion (since most of the action of the book takes place on and around Titan.) But there is news which would potentially require me to revise the novel slightly – not about Titan, but about its sibling Enceladus. You may have heard something about this, but I’ll go to the Bad Astro Boy himself for the news:
Life’s cauldron may be bubbling underneath Enceladus
A few days ago I wrote about how the Cassini Saturn probe dove through water ice plumes erupting from the surface of the icy moon Enceladus. The pictures were incredible, but it may very well be that the other detectors got the big payoff.
They detected organic compounds in the plumes.
Now remember, organic molecules don’t necessarily mean life. What Cassini detected were heavy carbon-based molecules, including many that are the building blocks for making things like amino acids and other compounds necessary for life as we know it.
Edited to add: Carolyn Porco, imaging team leader for Cassini, says:
[…] it is now unambiguous that the jets emerging from the south polar fractures contain organic materials heavier than simple methane — acetylene, hydrogen cyanide, formaldehyde, propane, etc. — making the sub-surface sources of Enceladus’ dramatic geological activity beyond doubt rich in astrobiologically interesting materials.
Whoa. I mean, *whoa* . Seriously. It ain’t life, nor even proof of life – but it is *damned exciting*.
Now, a nap. All this excitement makes me tired.

Well, there’s been another surge of interest in the book the last few days, and now there have been over 8,100 downloads of it.
As I told my wife on our morning walk today, saying “over eight thousand” sounds like a lot. I mean, it’s not just some kind of flash-in-the-pan interest thanks to one posting on a SF discussion forum or something. Over the last thirteen or so months, there has been a continued interest in the novel. And one of the most interesting things is that it largely seems to be due to word-of-mouth – I can only track about 1,200 downloads back to people visiting from other sites (and that is being generous in figuring that just because someone visits from a link on a site they decide to download the book.)
So, I decided to take a step I have been putting off for a long time: this morning I sent a query to a literary agency. In fact, I sent it to one of the agencies I had selected as being a good fit a year ago – they were one of only three who even bothered to respond to my query (of 9 or 10). And they turned me down, saying that they thought the book sounded interesting but were “insufficiently excited” about it. Here’s an excerpt from what I sent them today:
About a year ago, I contacted you concerning the possibility of representing me and my work. Your assistant at the time kindly declined on your behalf. But a lot has happened in the intervening year, and I would like you to reconsider. Given your long history working with science fiction authors, I still think that you are the agent for me.
My finished novel is discussed below. But first allow me to explain briefly why I think you may want to reconsider representing me.
When I set out to find an agent early last year, I also decided to put my novel online, available as a free download in .pdf form. Since then, over 8,000 people have downloaded the book. Some of this has been due to mention of the book in various forums, but that only accounts for about 15% of the downloads, according to my server statistics. The vast majority seems to have come about entirely because of word-of-mouth. And those numbers of downloads have continued to slowly grow. In the last week alone, almost 350 people have downloaded the book.
Shortly after posting the book online, I also started a related blog. The numbers there are not huge, but typically run about 100 visitors per day. Comments pertaining to the novel are almost uniformly very positive. Many people indicate that they are eager to buy the book in conventionally printed form. One person who produces audio books as a sideline was so enthusiastic about the book that he produced an unabridged audio version and made it freely available to me to use – this has just been added to my website in recent days.
Over the past year, as I was the primary care-provider for a family member with Alzheimer’s living here at home (culminating in her death last month), I also wrote about the experience of being a male care-giver for my blog. When I cross posted those entries to other forums, they always received a very enthusiastic response. That series of blog posts runs to about 40,000 words, and I am now planning on developing them into a book on the subject – a memoir, if you will.
So, we’ll see – see whether that is sufficient to entice them to represent me, or if I just get another rejection. Rejection hurts, kicks you right in the ego, there’s no doubt about it. But it is a necessary part of the process. And all of you who have downloaded the book, who have told others about it (and my blog), who have sent me comments and feedback – you all have made it easier to face the prospect of rejection. Thank you.
I’ll keep you posted. This is just the first step – in coming days, I will probably spend some time to select a couple of other agencies and contact them as well. We’ll see what happens.
