Odds and Ends from my brain and interests. Given that it is meant to be much like my old cartoon strip at the Lowell Connector, I suppose it is eponymous (I also like that it does make an oxymoron of sorts)

If there is to be anything here of any regularity it should be about sci-fi, computers, technology, and scale modeling with origami thrown in on the side (at least not infrequently). Oh, I would also expect some cartooning too

Mod Mon: Paper Dragons and Workshops

Workshop Models: Paper Dragon - a simple paper models for beginners

Umpteen apologies. This link should have been put up ages ago, but I kept putting it off. This is the posting for the dragon paper model I created for a Fast Track workshop at Arisia 2014. The original purpose was for a fast paper model that kids could build. It needed to be easy to put together, require minimal instruction, and at the same time would look somewhat interesting. I had a chance to do this again for 2016, so here's the update. Since then, I did another workshop and another model which I will be adding soon (a familiar telephone box).
     The initial section is some ideas and experiences of doing card modeling workshops. If you just want that dragon, then skip down a bit.

A word about Workshops - Read if planning for one

     The thing about workshop models is that typically you have very little time to work on them, generally not much more than an hour. Age is also an issue when designing or picking out a kit for it. You should consider the subject matter. While some of the simpler things to do are basically boxes or cones, it pays to make it somewhat interesting to your intended audience. Young children don't always sit still for long periods of direction and instruction, particularly if the rest of the room is running around doing something else. Even when working with adults, consider that the time for direction and instruction will take away from the actual build time. As a result use a kit with few parts that glue together easily. You can take advantage of subjects where the location of parts are more self explanatory, such as cars for example - where the wheels go is fairly obvious (see discussion about Knowledge in the World and Knowledge in the Head from Don Norman's Design of Everyday Things).
     While there are many things that are just a box, even a box can be made a little more interesting with a little detail skinning, like a Borg cube.It is possible to do interesting things with cubes as well. if you stretch a cube out into a rhomboid and it can be a racer or a rocket, and still be not much harder to build. Some Minecraft and Hako subjects can fit that bill nicely.
     One thing to also consider are the costs of running it. While it is nice when the people running the workshop can print the kits for you, ideally on a color laser printer, the cost of color print outs can add up. Picking a kit that uses only a few pages, say just 1 or 2, can make that more manageable (truth be told, I can barely manage a dozen builds at a time, so 16-20 kits is pretty much my max for print outs). Another strategy is picking out kits that are basically monochromatic. Here you can take advantage of using a standard black and white laser printer or even a photocopier to create the kits and simple use colored card stock instead of that valuable ink. Sci-fi subjects might have an edge here given the number of subjects that are mostly white with just a dash of color here and there.

The Dragon - a beginner model

     The dragon is a design idea that allows participants to color in and finish it in whatever fashion they saw fit. Given that the original workshop was for Arisia's Fast Track, which is for ages 6-12, I also wanted to keep it fun and light, but more intricate than a Borg cube. The model has very few parts, goes together easily, and be very forgiving of poor folds and missed attachment points. There are also certain obvious locations for the parts, i.e. head goes in front, tail in back, feet over the leg stumps. The only drawback is the zig-zag of the tab/scales can take a while to cut, but it doesn't have to be perfectly cut either.. It's also cheap, being just a black line drawing; ready made for photocopiers or black and white laser printers.
     The design doesn't use internal tabs, but instead uses the outward spines as external tabs to attach several parts. These are matched up and glued together. You shouldn't need an X-acto or any such implement to cut this up - safety scissors should do just fine. Tabs are fairly broad and cut at obvious angles so while scoring folds would help, it isn't necessary. The parts should naturally fold along crease lines.
     I encourage builders to color it in any color you want and it will be easier to color in before assembly. Felt tip pens are better as you are less likely to accidentally draw over glue points, but the way the glue points are designed (external tabs), you should be ok even with crayons (the wax in crayons would normally make gluing pieces together difficult). Another design idea is gluing things onto the finished version, such as from colored paper scraps or construction paper. The wings themselves are only printed on one side, so you will definitely have to finish them off on the reverse side. While ideally you do want to use card stock, which is available in various colors from office supply stores or craft shops. I have printed this model on construction paper (you will probably need to cut it down to 8.5"x11" to fit into your printer) and it does work, but construction paper is flimsier though and dragons made of this are more likely to suffer from wobbly legs and flimsy wings. In this case, some strategic reinforcement from scraps might solve that problem.

Basic Dragon Instructions (text)

You will need some scissors and glue. The parts represent 2 mirrored halves of the dragon, the left half and right half. Let's start with the head+body first:.
  • The body consists of 5 parts: The left, the right, the head spacer, the stomach spacer, and the tail spacer. Instead of tabs that glue on the inside, the "spines" are the glue tabs. After cutting those parts out, fold the spines out slightly
    1. Glue the two halves together. Bend the spines back a tad, and put a drop of glue on each of the top spines. Then match the spines from each half and press them together to glue. Allow it to dry. Suggestion, don't do all at once, start at middle, then do the ends.
    2. Open up the body in the middle and glue the stomach spacer by gluing the spines together like you did before. You will need to fold those spines outward a bit to make that easier. I have found it works easier if you only do one side at a time, put glue on the dragons spines on one side, attach the spacer, allow to dry a bit and then do the other side. Once dry (2b), pinch the nose and open it up a bit by squaring off the "upper lip" (unless you like it pointy).
    3. Get the smaller head spacer, and glue these spines to matching spines under the head much like you did for the stomach (one side first, then the other). The head spacer also includes the lower jaw, so just glue the spines.
    4. The tail spacer and fins attach like the head spacer. Simply match the tail fins to the underside fins on the tail of the body
    5. The front legs carry the wings. Glue the center of the roundish shoulder of the front leg, and on the leg stump on the body, but not the base of the wing. You might want to fold the wings outward slightly at this point to glue the wings pinned back.
    6. Attach the back legs by gluing the hip area of the leg over rear stump on the body. Once dry you can spread the feet and legs as necessary to get a proper stance for it
  • To some extent, the positions of some items can be shifted slightly. Perhaps more importantly, feel free to modify some parts to better suit you. If you want different wings (say butterfly wings), feel free to cut them off and draw up your own. Another idea is to paste stuff on it like bits of paper to make scales or build out the wings and tails with strips of colored paper, whatever.
The jpeg version can be modified with simple photo imaging software. The original design was limited by keeping it to a single sheet of paper. Whatever you can imagine would be fine.

Arisia Fast Track 2016 Bonus

I had a spare set of kits for an experimental one I was ironing out at the time. This character, a certain Encoded Bill is a fairly simple build, and still kind of beta, but if you are willing to try it out, the kit and instructions are here. I'll go into more detail for the next workshop blog entry. The only thing to say here is that I did make it with a "following eye" feature which you can try out. It involves cutting out the drawn eye, and placing the pupil piece provided against the inside back wall behind the hole. It's otherwise a fairly straightforward triangular box, arms and legs fold over for strength and to create feet arms. A simple forehand and flame part allows you to finish off the hands nicely. Good luck trying it out.

In Black and White (color it in) or in Color and the instructions (Links included as soon as I perfect the "following eye feature).

Enterprise vs Millenium Falcon?

Recently Io9 posted a youtube video where this question was posted to various celebrities attending the San Diego ComiCon (link to article here). The answers for the most part are fairly poor, which is surprising given that these are all people in SF. The exception is Adam Savage who does know his SF tech tries to argue from a visual history of the respective franchises, and Cas Anvar who knows how characters drive plots: "Han Solo has got way too much luck."

Star Trek vs. Star Wars?

The whole area has been filled with many pages of acrid forum threads and loud discussions at con panels (in good fun of course). Perhaps the most comprehensive (to be kind) collection of pages on the matter are those written by Michael Wong at StarDestroyer.net. The general tone of the entries shows a strong bias  for the SW empire over the ST federation. On the other hand, there are many ways in which it is obvious that the Star Wars universe from the point of view of weapons and warfare is immeasurably superior to the Star Trek's Federation. Of course this can get ardent trekkies in a twist, but to be fair it is tied to the very nature of the universes presented. Staying away from books and "technical" manuals, and only sticking to what has actually been put to film and video, the evidence is there.

Domain

The Star Wars universe encompasses an entire galaxy. The Federation and immediate boundary domains (Klingons, Romulans, et.al.) only encompass a section of the galaxy. A sizable section, but only a section nonetheless. By the very admission of its creator, Gene Rodenberry, the vast volume of the Federation territory remains largely unexplored. In fact it is the very reason the exploratory mission of Starfleet exists. The Star Wars galaxy on the other hand is vastly populated by diverse cultures interconnected by a vast commercial network and controlled by a strong centralized bureaucracy. While they are worlds that may be considered "backwater" planets and planets about which little is known but not totally unknown. In, ESB, Luke is told to go to the Dagobah system, and that seems to be information enough to get there, in spite of being a theoretically uninhabited planet whose sole resident picked a place to literally get lost in.

Travel Capacity

The Star Wars universe allows travel via hyperspace pretty much from any part in the galaxy to any other part within a day. The Star Trek universe, and specifically the TV Star Trek universe requires long periods, of days and weeks to travel from one extreme of its territory to another, which are only sub-sections of the federation volume. Obviously Star Wars ship command an all important power in any battle, the ability to engage and disengage at any point at will.
     Some of the video commentators mentioned the difference in maneuverability of the Enterprise vs. that of the Millenium Falcon. On the other hand, the main ships of the Star Wars universe wallow about space like puffy white clouds rather than battlecruisers. In some of the newer, updated effect sequences of even the old show, the Enterprise and other Constitution class vessels are shown to be able to maneuver and shoot quite well, much better than any Star Destroyer at any rate. On the other hand, the Star Wars universe can count on swarms of highly maneuverable fighters than can stand up to close quarters with a Star Destroyer.

Offensive and Defensive capacity

This is the one place where I would consider handing the advantage to the Star Trek universe with one exception. Star Wars weapons are shown to create explosive  heating and electrical disturbances (arcing) on most targets they hit. The energy delivered can be substantial. At no point, however, is a Star Wars blaster or laser from either armed personnel or ship weaponry shown to actually destabilize the actual matter of the target; i.e. make them just disappear. This is, as many a redshirt discovered, a somewhat everyday thing in the Star Trek universe. The energies involved represent orders of magnitudes in difference.
     The one exception in this Federation superiority would have to be in the destructive force of the Death Star. While it is admitted that it would take "thousands of ships with more power [than currently known]" to carry this out in that universe, it nevertheless does manage to boil away an entire earth-like planet within a few seconds. That is really huge.
     Defensively, is a harder call. Both universes have shields. The Star Wars universe seems to allow larger ships to be able to sustain direct hits from their weaponry with little serious effect, other than heavy shaking, as long as the shields are up. Similarly, Star Trek shields seem to provide similar support. Here I would tend to call it a draw.

Sheer numbers

The Star Wars universe is an entire galaxy, and the main nemesis, the Empire, can count on a huge number of ships to bring to bear in a military situation. The Federation, while large, particularly in it's last shown "Next Generation" phase, is not as large as that shown or implied by the Star Wars universe. Of course the problem here is that for the Star Wars universe, we are not explicitly told what that size may be, but to realistically control an entire galaxy full of sentient populated planets (see Domain), it would really have to be big, if spread out.

 But how powerful are they really?

And this is where it all breaks down. You read up on StarDestroyer.net's calculations and citations and one comes up with yields in the hundreds, thousands, or millions of Gigawatts of output on their laser blasts. In spite of this, rarely is the actual damage caused by a hit from these weapons on ships (innocent asteroids notwithstanding) show damage in this range, the kind of damage that should vaporize small fighter craft and boil away huge holes through the entirety of a ship. Even the starship Enterprise rarely boils away asteroids or generates small novas with their photon torpedoes which are described as micro-antimatter  bombs (1g of antimatter with equivalent of matter or 2 thousands of a Kg mass should yield about 180 megajoules or 43 kilotons  or nearly 3 Hiroshimas).
     Then again the damage shown has nothing really to do with the theoretical or purported yields of the weapons involved. The key differences between the two franchises lies in the foundations they rely on for their story telling. It is also tied by the primary medium they serve; namely movies in the case of Star Wars, and television in Star Trek.
      Star Wars is an epic saga of warfare and adventure by a few individuals embroiled in a galaxy wide war. Battles are spread out along different isolated planets, encompassing major fleet actions and yet well within the visual range of each other, sometimes only a few 10s of km or less. Moreover,  the principal weapon used, or at least actively shown in the thick of it, is the fighter. Capital ships while visible don't seem to be as much a part of it as the fighters are, in spite of the fact that they are occasionally shown to be more than capable of taking each other out. When one looks at it, it does remind one of World War II movies, and indeed the destructive capabilities of the fleets in action do seem to reflect those seen in classic war films like Sink the Bismark, Pursuit of the Graf Spee, Flying Tigers, Flying LeathernecksTora Tora Tora, The Battle of Britain and  The Bridges at Toko-Ri. George Lucas made no bones about the fact (at least initially) that his stories were based on 1930s serials and WWII movies. The parallels to the first Deast Star attack to Dambusters (which includes direct transcriptions) and 633 Squadron are undeniable. So, it is not surprising that the basic mode is more like the Pacific in WWII. There are bases on planets (islands) that can be assaulted by heavy starships (battleships and cruisers, Longest Day) that can in turn be defeated by extremely heavy land based ion cannons (Guns of Navarone), other heavy starships (Sink the Bismark), and more generally by small fighters and light bombers (Tora, Tora, Tora). In the mix you throw in the MF which is like a PT boat. The destructive power is in that sense is similar in order to have similar action sequences as the ones seen in those kinds of films. We are not talking kilotons here.
     Star Trek, on the other hand, doesn't even have the word "war" in the title. As a result the "E" is generally only as powerful as necessary for a given plot. It is also not generally used as part of a fleet, so it needs to be able to defend itself independently. The 19th century sailing adventure stories where single ships generally only slugged it out with other individual ships of a similar class - armed worldwide cruisers - is the principal model for this type of story. Gene Roddenberry professed that Kirk could be seen as Horatio Hornblower in space. Fleets of this period patrolled alone in far off oceans typically  protecting trade, initiating contact with new cultures, first contacts with islanders, colonization, reconnaissance, and just plain scientific exploration. When there was warfare, it was intense, but slow, allowing the captain to get advice from his first officer on best tactics while under fire. Federation starships can withstand detonations of incredibly powerful weapons at point blank range, which like the way pirate movies have ships can fire broadsides at each other and yet some how, Error Flynn can still command a ship.
    Star Trek stories tend to start when you get somewhere and end just before you leave. For the purposes of plot, you can't get help from anywhere particularly quickly or run away quickly so the vastness of space is a plus to explain why you have to resolve your story within the confines of a 1 hour episode, basically exactly where they are. The 19th century sailing adventure fits that bill rather nicely. Unfortunately movies, and an increased demand for faster paced stories has somewhat killed that. Star Wars is really the epitome of space opera. Space opera is by definition epic, but as a movie it has a limited amount of time to tell a story. Space Opera also require action. Things have to happen, one right after the other, so you can't have "all that tedious mucking about in hyperspace" type stuff. Vast distances of a galaxy have to be covered in less time than what it takes for the next bathroom break. The threat has to be eminent, and not surprisingly armed to the teeth. Star Trek has not escaped this as the movies have also relied on much more warfare and destruction to keep the action going. The need for speed has even been epitomized by the last Star Trek movie which presented negligent travel times between Earth and the Klingon home world either by ship or nearly instantaneously by transwarp transporter (even instantaneous communications; the days of Uhura saying it will take several hours for a reply from Starfleet are gone). Whereas in the original series starships were rarely destroyed in warfare, battles where much more the norm in the DS9, Voyager, and Enterprise incarnations.
     So how powerful are they? Well in the end, really only as powerful as they need to be. To expect consistency, particularly from the film franchises, is chimeric as well. The levels of technology are as Arthur C. Clarke would have it, no different from magic as far as an observer from the late 20th or early 21st century would see it. There is definitely a certain enjoyment one can have from trying to figure out how many Gigawatts a weapons system generated or the number of g's pulled by a ship during some maneuver, but in the end I really wouldn't expect the writers of these franchises to put anywhere near the effort to figure it out and film it accurately. From their point of view, they want to tell a story in the best way possible. If that means you can hear explosions in space, so be it.
