Comment Re:It doesn't work that way. (Score 1) 113

what we're saying is that arranging for velocity AND position to be 'null' at the same time is harder than simply arranging for velocity to be null and position to be +/- 100m(or so).

*Sigh*
 
I understand what you're saying - but as with my previously reply, you don't grasp the problem.
 
The appearance of the vehicle "working hard at the last second" during the first attempt was a consequence of running out of hydraulic fluid - and would have occurred regardless of the size of the target. The appearance of the vehicle "working hard at the last second" during the last attempt was a consequence of the throttle valve not operating to spec - and would have occurred regardless of the size of the target.
 
From the point of view of the final landing sequence it's not all that much easier to arrange for velocity to be null and position to be +/- 100m than it is to arrange the same +/- 1m. Selecting a landing point occurs at a relatively high altitude (and on a, relatively speaking, relaxed timeline) and final trim starts around a kilometer or so up (AIUI). From there, jittering the variables (burn time and timing, gimbal angles, and throttle settings) a tiny amount one way or another to maintain targeting isn't a substantial burden (on the software or the hardware) compared to the much larger problem of nulling your velocities.

You're talking about some kind of articulated arm (which can survive being essentially inside rocket exhaust)

I think you're picturing something different. I'm picturing something pretty big that comes in from the sides, staying well away from the exhaust.

That just makes an already heavy, complex, and expensive system even heavier, more complex, and more expensive than I envisioned.

I don't believe you actually need a pilot's license to fly anything characterized as an "ultralight" aircraft, as these tape-and-balsawood gyrocopters appear to be. Doesn't mean the FAA can't fine your ass, of course, when you do dumb crap like flying a possibly deadly set of large rotors right past crowds of tourists at low altitudes in an urban area like DC.

To your point (sorry!) There is no "fault". Girls tend not to care about STEM subjects. It's that simple. STEM requires endless hours studying alone, about subjects that would bore an anvil to tears. We literally drug our children to hold still and have the stuff poured into them. It isn't for everyone; that's why so many antisocial types gravitate towards it. You either like it, or you don't.

Teachers don't "fail" - students fail. And "failure" is not the right word. You can't force interest into a human child like some personality-altering enema. A teacher can instill the basics of how to be a human being, like history, and arithmetic, and reading. The rest comes from the child and the matrix the child lives in. You can't manufacture Alan Turings, and God help us if you could - the world does NOT need to be composed of semi-autistic math prodigies. We need the other types as well.

Let the DAMNED children become what they want to become. Here's a poser: has any one of these STEM-pushers asked the kids what they think about their "failure" to become good corporate tech fodder?

The whole "privatize schools into moneymaking ventures to raise test scores and thus provide cheaper, better labor for corporations" IS the experiment. But finding failure in the experimental results will not be tolerated. The schools will be turned into corporate labor factories, and we've no mechanism to stop them.

What are we losing? Imagination. The overworked, no-time-for-play lab mice have no damned imaginations. They will not be able to grow their minds that way. That requires free time, and freedom to wander around and do nothing but dream. That is no longer tolerated. Damaged mice. And eventually, a damaged culture, a passive, corporatized citizenry that can't even perceive what it has lost.

And oh yeah: this is being done because employers want more job applicants and thus will be able, over time. to turn STEM jobs into a paper hat minimum wage paradise - for them. They are sick at the idea of all that money flowing out of their platinum parachute accounts and into the pockets of mere laborers. It has to stop!

Perhaps girls aren't as interested in STEM subjects as boys, because their intrinsic culture, the floating "girlness" passed on from mother to daughter and from playmate to playmate, veers towards social interaction and the softer subjects. STEM is inherently a loner's paradise.

Reengineering people is not a good idea. Girls will find their own way into whatever they wish to do. You can't force them to like what you like, no matter how many Starfleet academies you lock them into.
