Oh goodness, I didn't mean to imply that capitalism is bad/evil. Re-reading my comment with your comment in mind I see that it is easier assume I meant all of that in a negative way than pick and choose;~)
The only 'evil' I wanted to point out was the justaposition of our supposedly democratic nation with reality.
hmmmmm. I rate that highly, but will raise the question of how they get the raw materials;~)
I know that much of the furniture that is 'Amish Made' does indeed come from trees they farm and fall themselves, so I guess that would be a true winner -- hand fallen trees, hand hewn furnishings and a horse cart to market.
Nifty.
Boy, if society collapses the Amish are going to be swamped with people trying to learn from them;~)
There is no city, no state and certainly no entire country that can currently handle a disease with the ability to spread itself as easily as the yearly flu virus and has 5% fatality. 5% fatality means almost everyone that GETS it will want advanced medical treatment. Most of said treatment will just head-patting, but with a high fatality rate comes a high care requirement; many will need respirators, oxygen, iron lung, fluids etc, just to keep the lethality rate as low as possible.
Anyone that tells you that they are prepared for the coming pandemic is lying or stupid.
Until the POPULACE is involved, they aren't planning for shit. They are making people (mostly themselves) feel 'better, safer, happier'.
If you involve the general population and say 'hey everybody, here is your free emergency radio. If we hear about something bad about to happen, it will wake up and tell you stuff. Oh, and if we have a pandemic, stay the fuck in your house and don't even think about going to work, school or the grocery store.'
Because it will take a massive work stoppage, transportation shutdown, and generally complete economic destruction in the short term, to SLOW the spread of the disease long enough that the hospitals have a _chance_ at decreasing the fatality rate. Slow the spread long enough to study the disease itself. Maybe a vaccine can be developed -- or at worst you give yourself time to develop a targeted treatment regime and actually implement it on a slower rush of victoms.
Your response is actually the one bound to fail. History has many examples.
I will suffice it to say that submission has never won the day.
If the RIAA bothered to employ behavioral psychologists for anything other than predicting the next pop hit, I doubt we would see much of what has happened.
America has long paid lip service to democracy, but in reality it is very hard to 'do anything' through channels. As citizens, we've a long and flowing history of passivly ignoring laws we thing are bullshit. Think 'prohibition'. Think 'pot'. Prostitution. Etc.
If we *really* wanted to end prostitution, it would stop. Same with pot-smoking. The reality is that most people just don't care enough _either way_ to get actively involved in politics. Or, honestly, to even understand the issues.
When people who DO care get involved, they see a large body of ignorant people being led around by corrupt polititions who, in turn, are being led around by large sacks of money held by 'corporate sponsors'.
If we were to sit back and say 'oh! Shit! Our bad! You're right guys, what we were doing was wrong!', then you people who are happy to sit back and ignore politics would and up having digital restrictions managment that makes this shit look friendly.
When Big Music takes a little lesson from history, they will figure out that a middle ground option will be significantly more effective than any draconian measures. Tagging songs with individual IDs and occasionally prosocuting the hell out of large distributers would raise few hackles.
bah. Big Music will never get it. They are like the rapist that sues the victom for giving them an STD.
I know I'm being a pendantic ass, but it is a point readers need to remember: even if you do not yourself purchase gas directly, you are still using lots and lots of it.
Everything in the United States gets shipped by truck. EVERYTHING. It may be on a train or a plane for part of the trip, but at some point in time it was on a truck.

Understand, though, that I do respect those who can and do manage without using a car. I considered living in London, mostly because of the tube. Loved the hell out of the few months I spent there, even though it was winter. No car. Never took a taxi. Tube and a few bus rides. And a lot of walking.
If society were to crumble, and humankind were to revert to the savages we naturally would be without our artifical society, your only 'right' would be to defend whatever you felt you wanted with your life. Even it it wasn't really 'yours'.
Not only could one 'naturally' FORCE you into slavery, one could naturally decide to kill you, with or without your permission.
'Naturally', if any life form decided that you looked tasty, it would eat you -- if it could. Similarly, if said life form could make you gather food FOR it, with or against your will, it would make sense for the life form to do so. Naturally.
To argue that there is such BS as 'natural' rights is to defeat your own purpose. Rights must be fought for, and you must fight to keep them. To pretend that rights are natural, gifts from some mighty Entity... such pretension is a trap which will help those who wish to take advantage of you to do so.
Thats like saying that if I build a weapon and sell it to any 19 year old moron who wants one, I shouldn't be held liable if the up and shoot some storekeep with it!
small_angle in question is on the order of tan(1000 km / {2.9978E8m/s * 1 hour})
(that is 1000 km / 1 light hour)
0.000053 degrees.
That assumes bodies which are one light hour apart and on the order of 1000km in radius. That is to say *VERY* close together, and *very* big.
Except for incredibly detailed calculations, most models of the solar system assume that the earth-moon system is a point. Those models take a LOT of power to run. You also have to take care not to run into floating point issues in those kinds of runs. Real easy for your trillions of round off-errors to come back and bite you in the ass.
Easier to assume a constant 1 newton of thrust on the whole system; while the actual thrust WON'T be one newton, it is a convienient way to 'scale' it when you get a real number (which would be more like.4 newton, or.1 newton, I would guess).
The thrust of the rocket engine BY DEFINITION must also be the thrust of the 'system'. If the engine exhaust didn't leave the 'orbit' of the asteroid, then there would be no net force on the system as a whole. It would STILL be possible to hover, however! (Note: helicopters do not affect Earths orbit). There will be some losses, but Ion drives have very fast exhaust; I doubt the losses will be significant.
Think of a model rocket. On the ends of the three fins, tie 20 foot long kite strings. At the end of the kite strings, tie a pebble. Now launch it. (please, don't do this for real anybody!)
The asteroid is the pebble. Gravity is the kite string. The spacecraft is our metephorical rocket. The scale is all wrong, of course; the spacecraft will be tiny compared to the pebble, not vice versa. The idea is similar though.
What I think you missed is that you can't drop the mass of the asteroid from the equation like that. It looked cute, at first, but it started driving me batty.
Yes, you sortof have the acceleration of the asteroid (Ma) due to the spacecraft (Ms). However, you neglect the MUCH larger force of the acceleration on the spacecraft (Ms) due to the asteroid (Ma). What you really wanted to do was divide the Force by the mass of the spacecraft; we normally ignore the effect of the tiny mass (the craft), not the effect of the orders-of-magnitude-larger mass.
Hollywood still thinks they can make typing exciting -- an asteriod getting moved out of Earths way over span of decades... hell, sound like a challenge to me!
Maybe they'll try throwing in someone getting a blow job again. That almost worked with the whole typing-as-an-action-sequence thing.
130 meters isn't much of a threat though (pleasepleaseplease don't land on me though). Even baby world-killers are over 500 meters.
But yeah -- saying 20 tonne craft means 'a freak'n spaceship big enough to get there!'.
Which only goes further in the direction you mention; at 500 meters radius (1km rock) using your density one ends up with 1/2 N occuring at 2047m from the center of the rock; so at an altitude of 1500 m.
Thrust divergence angle would be (for a sphere) adjacent: 2047m, opposite: 500m (radius of rock).
tan (opp/adj) = 14.3 degrees.
Actual Force =.5_N*cos(14.3 deg) =.4985 N = 96.9% of force in correct direction
Now, lets do that again with a spacecraft 10 times larger! 200 metric tonnes!
Hover distance at 1/2 newton: 6475 m
Thrust angle: 4.43 deg
Actual Force = F*cos(4.43 deg) =.4985 N = 99.7% of force in correct direction
Wow. While not pointless... it would only be worthwhile if it were essentially FREE to add the mass. Wait.... We haven't run the full sim. You have to MOVE the extra mass too! So, in the end it probably works out nearly equal. Unless of course you have 10 times the power, but I digress.
Land is NOT scarce on this planet. We could all spread out and own a good number of acres --
world land area: 510.072 million sq km (cia world factbook) = 126 billion acres
world population: call it 6 billion (CIA says 6.5).
126E9/6.5E9 = 21 acres per person.
Game land could be infinite. Nobody would care. The price would be the same.
People go where the people are. People want to be where 'stuff happens'.
It is also a transportation issue, of course, just like in real life. Look what the car did for the city in real life! If a game created an instantaneous free transport system (teleport anywhere you want, from anywhere!), as you (i think?) suggest, *AND* infinite land area... THEN I could see scarcity (or lack thereof) becoming an issue.
Anyway -- this stuff would be fun to model (and get paid to model it, of course;~) )

Because we live in a democratically elected plutocracy.
Democracy? Where?
The United States is a Representative (somewhat socialist, mostly capitalistic) Republic, when it comes to the federal level.
We do NOT elect the president by direct democracy. We do not vote on anything at the federal level.
Which just shows I have no arguement with your point.
acronyms like DRM
Digital Restrictions Managment.

Honestly now, how many Best of What's New features have YOU seen in real life? Bet you can count them on one hand.....
I actually meant 'Semi' for the most part.
The amish part wins, because _some_ Amish communities are ALL natural; they don't buy anything at all and essentially live directly of the land.
All commercial farms get massive amounts of stuff delivered to them via truck, and couldn't survive without it. At least not without changing a LOT.
Gas for tractors, fertalizers, mulches, seeds, lye etc.
hmmmmm. I rate that highly, but will raise the question of how they get the raw materials ;~)

G = 6.67259E-11 m^3/(kg*s^2)
Me = 5.967E24kg
