Sigh.  Math describes bad shooters equally well as good.  Treasure Co. Ltd. made Ikaruga, a [to sum up, very nice] vertical scrolling shooter with a polarity mechanic where your ship could change colors from bluish white to reddish black to counter your similarly binary enemies.  Since then I have searched for doujin games which use or extend this mechanic.  One mathematical progression is particularly alluring from one gaming viewpoint, and damning from others:  non-transitive graphs.  In Ikaruga or a clone thereof, there are two kinds of "tie" between bullets and ships: destructive, and safe. One avoids fulfilling one's end of the bargain by dodging or switching colors before your bullet-ship interaction occurs.  In three-color variants, the colors tend toward a Rochambeau relationship, with no need for such dancing against individuals so long as your rock beats their scissors.  Thus you can win against any one color on the screen.  To extend this to two, you would need not five, but seven colors.  And for three, and this is where humanity's knowledge ends, the number is nineteen.  And also absurd.  But seven is just on the wrong side of tempting.  And for me, that's still tempting.

Things four [Aug. 25th, 2008|03:43 pm]
[mood |contemplativecontemplative]
[music |Sugarcubes- Ammæli]

1) I've just figured out: Three-section staff and whip chain and other soft weapons are stacked at the high end of the Shaolin training regimens because self-injury of practitioners, especially during combat, is injurious not only to their bodily integrity, but their schools' reputations.  They keep these weapons because competent users do help said reputations.

2) Web-garnered knowledge has an annoying property.  On the one hand, I can learn enough to make predictions about how things work and feel all scientific when they are borne out.  On the other hand, often the only reason I find said properties discussed in accessible format-- instead of being tied up in wiltingly expensive journals or patents that spent most of their verbiage claiming absurdly general things-- is that I've discovered a message board where pseudonymous folks are discussing how best to make some nicknamed substance or other without alarming their neighbors or choking or exploding or such.  That, or it's on Wikipedia.  The line appears to be blurry sometimes.
*sigh* Someday, I _will_ assemble a strong ampoule or such which can be placed in hot or cold baths and allow the opalescence of a critical consolute transition to be observed within.  I bet it can be done without such glassworking, and I'm almost certain it can be coaxed out of ordinary isopropyl alcohol in brine, but the relevant pseudoternary phase charts are nowhere to be found!

3) I've finally found an explanation for a family of sundials that relies on pictures to explain the relevant geometry instead of trigonometric functions.  Great sanity check to see if you've misremembered, and more extensible too.  Within that family I've discovered the Foster-Lambert dial too, which offers many opportunities not normally afforded by sundials in its circular, evenly-marked shape.  Setting and adjustment.  Scope of starting materials.  Even... steampunk possibilities.

4) Faraday rotators.  There has to be a way to exploit them in nonimaging optics, and I mostly mean jewelry.

I still want to make sundials.
I'd wanted to invent a particular type of sundial for a while, one which includes a map of the world projected onto the plane beneath the gnomon (pointer) such that one could tell where in the world it happened to be apparent noon, and where in the tropics the sun was at its burningest position, directly overhead.  It's been done.  A mathematician (/cartographer?) named Franz Ritter figured out the projection long ago, which flying people still use, and some guy's got a whole website selling these things, rich-artist prices too.  Meh.  Now I can only make, not invent.  Still, there should be joy.  Besides, there are more surfaces to work with than just the horizontal plane, and I can replace the gnomon with, say, two wires in a bifilar setup for a we-have-you-now-Mr.-Sun crosshair effect and I can also find where the antisun is its antiburningest at the moment by using an antipodal map of the world.  I also want to make an analemmatic dial using marked string in lieu of the ellipse,  which is fine for an already-interactive sundial, I think.

I think a lot about energy.
I wonder where the next step in cellulose extraction for paper and/or dissolution for alcohol-of-choice/HMF/hydrogen production will come from, and whether people will ever start using more efficient, known means for extracting ethanol from water than distillation.  I wonder how the osmotic-energy people are doing with their semipermeable membrane biofouling issue,  how the MCF people are doing with their tokamaks, how the skyhook people are getting their ideas accepted, and the space-based solar people with their microwave beam stations.  Not to mention the ground-laser-powered rocket people with their proof-of-concept flight nigh on a decade ago and then silence.  Are they broke, bought or both now?

I want to make sundials.  Mostly to expel into form my angst about political decisions with respect to the measurement of time that I developed in China and were reinforced by the recent Daylight Savings tweak by our unpopular leader.  But also because so many are like geometric proofs of the time, and indeed that there are so many forms of valid sundial .
  ...Apparently if I make a sundial, I will have become a "dialist." Now that sounds zhuanmen, it sounds niubi.  It also sounds nerdy.  Ah well, wherever the jock-nerd power pendulum lies, a nerd badge is an honor to accept.

Finnish pop music I like better than much.

I can blog again!  No longer need I "blog" at friends using instant messages.  For I have found my password!

Thus! I can rant about the merits of hydroxymethylfurfural as feedstock and ionic liquids and the Baffling Superconductor Of The Week and the perennially vexing energy problem and exotic atoms and excimer lasers and superradiant dyes and metal-insulator transitions and bipedal pendular running gaits and solvated electrons and negative-refractive-index materials and first-to-second-order transitions and the behavior of NP-complete problems in the trivial-solution-to-trivial-unsolvability transition and traveling-salesman problems on the space of character digraphs in natural-language text and screensavers that ought to be written and biofouling problems in osmotic machines and gem-quality high-Verdet-constant minerals and rules-of-thumb for phononic bandgap structures and the precession of the aphelion and oobleck and sonochemistry in coffea extraction and magnetohydrodynamic geodynamo simulacra and the needless complication of the equation of time and  the untapped brainpower of magpies and European starlings and why I'm somewhat glad supervillainous mad scientists don't quite exist because I think somewhere out there there would be a labcoat, a pair of heavy gloves and goggles that would fit perfectly which I would stumble upon in an otherwise-traumatic day, and then I'd have an automatic, noisome, overpowered archenemy, and I would get buttthwomped until I showed them all, SHOWED THEM ALL, and that probably means I wouldn't be a superhero, well, probably-- I can rant about any or all of it and I won't have to feel personally guilty at turning friends' eyes into at-signs when they need those for other things!  They can safely wait until they don't!!

Turns out I don't have said homework to do, as I missed a deadline to apply for the test in June! This of course is bad, but I feel a lot better, because the test is easily retaken and because it's above my proficiency level.
The moral of this lesson is ask multiple important people an unhealthy number of questions daily, double-check their words against bulletin-boards you read more frequently, and record all relevant dates and prices in your handy pocket notebook.
For me this is a little like a story telling the reader they are being held responsible for, say, any cars they saw in their travels without noting license number and speed-
surprising, and sounds like a hassle. But of course it's more realistic than all that. *sigh*

In China, you can be thirsty for orange juice and mistakenly buy flan. Thankfully, the straw provided makes short work of flan. *nods, sips and chews demonstratively*
Speaking of flan, the sky's a most wonderful orange at the moment.

I was going to write more, but... [Jul. 7th, 2004|12:05 am]
Rock-paper-scissors-spock-lizard is a good update to the theme, and I want to make a game out of it that involves smushing and eating Skittles. I figured I could make it into a little wargame.
Wargames bring to mind massed battle, which are usually a lot more cloudish than treeish. I think they would more resemble the latter if the units were passing resources like booty or support one to another, like nutrients in slime mold.
I have homework to do. It is summer.
I still want to be a scientist, or a maker of games. I don't know whether or not these ambitions are right any more.
And it's closing time at the internet bar here.

*blinks, with more skill and strength* [Jun. 25th, 2004|11:22 pm]
[mood |indescribableclose in flavour to Nyquil]
[music |the warm side of someone's aircon... slush slush, fan fan!]

Being a little sick makes writing in foreign languages hard, because your body has several fronts to fight on, and the thinking part is no longer mission control. You do not know this, all you know is that your brain is swimming in a pool of Nyquil that you did not order, and your work is stirring up that very Nyquil.

That said, today was pretty cool. I found out that Brazilian restaurants around the world serve a lot of beef, and with real steak knives, and forks, which you can use to cut away the gristle! I decided to ignore whether or not you were supposed to eat said, and ate only lean today. It was refreshing to eat food that was designed to be eaten without chopsticks, to actually be stacked onto a fork. It also tasted reeeeally good, especially the water-chestnut salad in OJ.

And now that I've stopped working, my brain is fine!
