Consumers in this country get to take a shop to court for free. Well to a tribunal. It takes time but not hard cash. So far I have not had a problem and neither have quite a few of my friends. This also goes for DVD and CD that don't work in some players. I have always got my money back.
I have just now been denied a paper i need to do my work. Because the library only has up till 1985. The paper i need is from 1983. To buy it will cost $35US. So what are all those overheads for again?
In the long run, closed publishing is more expensive.
This may in fact not be the fault of the sony DVD player. A lot of modern DVDs are not compliant to the DVD standard in the hope that they "break" computer ripping programs. Bad sectors is the basic one, all Disney disks i have seen have this. Most DVD players will work. But higher end ones tend not too. They are too fancy and use more of the DVD spec. Ironic really. My code free dvd player that cost the price of a few beers works really well.
I know everyone likes to hack sony with the rootkit issue (there are other distributes still doing this in Germany). But really they are no worse and no better than the rest. Well there is one difference, they make players and are also a distributer.
Well at least in some countries they can't use a "opened no return policy". If the product can't be used for its intended purpose then they have to replace with "new" one that does or give a full refund.
I have done this in NZ with a game where the policy was "due to piracy concerns". But I made a fuss and pointed out the law and threatened to take it to the consumer groups and got my money back.
The huge amount of heat from earth. Earth is *always* almost half the sky for a object in LEO. And its pumps out a truckload of IR. About the same amount as it absorbs from the sun in fact. Hence the reason for deep IR telescopes are often proposed for far out points like L2 (i think or L3 --can never remember.)
The moon is a lot cooler in the night side due to no atmosphere and on average its a cooler "orbit" as well. But the real killer is between earth and the moon. Without proper thermal design. Its an ice cube. Well getting rid of heat is a big deal too. So it could be a heat box.
But really moving the ISS to the moon is certainly in the engineering crazy box stuff. You can't just "fix it" any more than a SUV can be made faster than a F1 car.
Now moving the ISS to a different LEO orbit... thats something totally different.
Now, closed access journals are generally free or close to free to publish.
The cheapest i have seen still has $50 page charge, with a typical article length of 15-20 pages. While I agree that BMC/PLoS are dam expensive. Its hard to claim is a unknown expense. Compared to a Post Doc salary, its not really much.
And how much are your overheads that the uni takes? This is partly used to *pay* for access to these journals in the library. Just because you don't see the invoice does not mean you haven't paid.
Journals that want high impact factor select articles that will get a lot of citations. This often means somewhat controversial results, rather than good science. Also "good" journals are often crap because of this. Almost every single physics fraud articles are almost exclusively published in nature and science. Its when the work hits the physics reviews that they get uncovered as frauds. Hell nature even published a homeopathy paper!
This still won't be enough. Being able to plot a hit point is not the same as this is where the bullet will go. 3 points might be enough for a 2nd order stage 2 physics question, but the real world has a habbit of throwing a spanner in the works.
The US at least was developing guns to shoot artillery rounds in mid flight. They were using a lot more data than 3 points and more data than just bullet parameters. The high supersonic speeds and the fact that *after* traveling 1000m+ you need to care about distance smaller than 20cm makes this a pretty hard problem (you can run the numbers). Wind changes over that distance is something snipers are trained about. It will need that data too at the very least. Or as the original post said you gonna get dodged right into the bullet.
Actually, your trajectory isn't flat out to 700m. It's just that the range setting on your sight/scope make it look that way.
"Flat" is a relative term. I use a rifle, I set my own sights, and have a PhD in physics... Hence the term "real" flat. I mean come on, you forgot about the curvature of the earth, and time dilation effects caused by earths mass. please.
You say this as a joke. Yet some C code i was forced to work on once. Well there was void, void*, void**, void*** and (void*)(void*). Or some other such nonsense. I don't recall exactly. But i had to check if it was valid C rather than some "compiler feature".
This is not quite the full story. lighter rounds are affected by wind far more than heaver rounds. I know the.50 cal and.308 are typical rifles used for this sort of thing, and they have high velocity but not the highest, but run heaver bullets. Also lighter bullets loose there energy faster than heaver ones. So too light and it will be going pretty slow when it gets there. Finally there is a limit to the velocity from the physics of gases and the chemistry that makes the highest velocity in the 1500 m/s range. And thats pushing it for a rifle. IIRC the.50 cal is more like 1000 m/s.
I have a.270 that has a muzzle velocity in the 1300m/s range (IIRC). Its a real flat trajectory out to about 700m but drops off real quick after than. We also call it a meat bruiser;).
Either way. I won't be counting on being alive after a.50 cal round or something that big. Even a.308 must hit you like a truck. Also what about light but higher velocity rounds --like a.270 or something. The energy from a 308 is higher IIRC but the velocity means the impact forces could be higher.
At these ranges wind modeling is mandatory. Even silly Coriolis effects matter. Remember a small perturbation is not so small after 4 seconds of flight (or even 1 second for that matter). Then there is the spin on the bullet which can affect its angle of attack that has even more effect at 3 times the speed of sound. This is not a fist order approximation problem.
The Devil is in the details. *But* it is well understood details. And if you know the details you can predict the trajectory quite accurately. Modern tanks do this, but then they have wind, temperature and humidity sensors in order to do this. In fact they also have a bunch of sensors monitoring the barrels temperature etc too.
That actually has a good sense of logic too it. Well more than vaccination causes it. Also the side effects are getting rid of Barney. Balone! its low quality, but from 5min its pretty funny.
I think your on the right track, but i think they way society is more more dependent on education now we tend to notice it more too. Also my wife works with these children. There are plenty of cases that really are misdiagnosed. The parents wants something to blame. Finally these things are quite rare, and a small change in false positives or false negatives can make quite a big difference.
I'm pretty sure downloading would be against the law too. Also I presume that code free dvd players are available and you can skip *anything* with most of the ones i have had.
I live in Austria now (Germany vers Austria is kinda similar). New Zealand and Australia have pretty similar "culture" really. But yea, we have better rugby players;) Only they all come from the islands these days.

I'm crossing my fingers for a post scarcity society. We'll need fusion or something, and I ain't holding my breath. But theoretically ....
Do you really want the average consumer to answer honestly? And what would you honestly buy? The $10 from china or the $90 one from "honest labor".

You mistaken. The pirates are not affected at all. Because the DRM has been removed.

Real sniper statistics are not used in Hollywood movies. Reality is - well - a lot more grimy. For want of a better word.
We pay over 1EU per Liter! Stop your complaining.
Don't laugh it is become a big problem in Europe where kids to get back a teachers..
Can you cite 2 such cases?

Hence the reason I now do my best to publish in open access journal only. However they tend to have higher page charges (PLoS I'm looking at you!).

However for those of you who are worried about being shot, if you don't want to die, keep your hands to yourself.
The rest of us just don't live in America. Talk about bat shit insane.
