Right...
If that's the level we're discussing it on then no... It's not possible to create a code that is able to determine if it is being used by the wrong persons who've somehow gotten hold of the key...
Nor is it possible to create a code that makes it impossible to get hold of the original plaintext on the source computer, or threatening the author to simply tell you what you want to know...
And no... I guess it's impossible to create a code that can guard against dumbass humans using them the wrong way...
Why on earth are you so convinced that this system behaves chaotically?
the WEATHER (different time scale) is chaotic... the climate doesn't have to be.
Systems that we don't fully understand are unpredicatable because... well because we don't understand them.
I've seen no indication that the climate is an inherantly chaotic system.
I looks like a simple bistable system, perhaps exhibiting some kind of relaxation oscillation.
I might be quite possible to understand the system and predict it if we just get the model right.
And what's this about chaotic systems being unpredictable... the weather is chaotic but we're able to predict it 5 days into the future (and the lyapunov coefficient indicates that it should be possible to get good 10-11 day predictions, WITH BETTER MODELS!).
Getting a 100 year prediction of the climate corresponds to what (in the weather time scale)? 3-4 hours... and the climate even looks more predictable than he weather.
While it is a fact that the CO2 concentration has gone up significantly in the past 100 years; from 290 ppm (parts per million) in 1900 to 366 ppm in 1998, if a change of that magnitude can set off a chain reaction then we would have been gone a long time ago. There are obviously mechanisms that prevent this from happening.
I've already had 5 beers... if a pertubation of that magnitude isn't able to push me over the edge, there has to be mechanism preventing me from becoming pissed...
BARTENDER!!! another round!
well it's definitely a nonlinear system, but chaotic is a pretty exact term...
The weather is chaotic, but the climate (different time scale) might simply be bistable.
The reason why we can't predict what'll happen doesn't have to be because the system is chaotic.
Most likely it's just because we don't understand the system. There's a huge difference.
Actually it doesn't have to have sufficient power to ionize the surrounding air.
Lasers are (if they're powerful enough) able to cause dipole radiation, without ionizing any molecules.
the dipole oscillations are oriented with respect to the polarization of the light, so this light is most intense if you see it from an angle perpendicular to the polarization.
It's true that weak lasers has to reflect of particles, but I'm sure that this laser is powerful enough to cause dipole radiation... (maybe the reason why the didn't just move the laser from the basement it's placed in)
There's nothing to convince me that the picture's a fake.
I've seen green laser that were intense enough to been seen by the naked eye.. If you look at it from the correct angle with respect to the polarization, of course
This can only be interpreted as the final, irrefutable proof that god is a shark.
I guess that a lot of people are left with a strange taste in their mouth after this...
including (but not limited to), the cast of: Jaws Jaws 2 Jaws: The Revenge
etc. etc.
The positions of all the trains is monitored somehow and relayed to the stations.
some of the the major bus lines have a gps system that relays information to some bus stops.
The bus company recently finished testing two systems... unfortunately I can't remember the winning system, but SkyBus lost.
The lines with most passengers and busses use the GPS system to keep an even distance between them at peek hours... this avoids the busses from clotting together and reduces the average waiting time for each passenger (works beautifully!)
There isn't an SMS system (although I know for certain that it's been discussed, I don't know where that project is currently).
Obviously this isn't about greedy Hollywood companies that wan't to earn more money than they allready do.
This is about having your name linked to work you didn't do.
They're mutilating peoples work and selling it with the original names on it... I know that I would be pissed if someone republished one of my scientific articles but removed an essential part of the argumentation without my consent.
If someone introduced errors into my code and still told people that it was my program... I would probably get pretty mad, but judging from these comments I'm probably the only one.
Nothing wrong with making censored versions of movies, but it should be the artists own choice... If they don't think that the movie can survive censorship then maybe it's just pointless to show it to kids anyway.
This is a major threat to the safety and freedom of american citizens! I think that the US should try to stop this "Big Crunch", WITH OR WITHOUT support from the UN or the European nations...
I really wouldn't worry too much about it, being first grade and all...
I didn't become interested in really geeky stuff until much later.
And anyway math isn't REALLY interesting untill you you get to a sufficiently high level.
I guess that the early on the primary thing is to avoid becoming scared or getting too many knocks...
maybe teaching her some tricks, like
Trachtenbergs methods would help her feel good at it.
(this is the original book... i bet something better has cropped up since).
The methods are amazingly fast though...
(being able to add as fast as the bar code reader at the supermarket is really neat in a geeky kind a way:) )
Feeling you're good at something certainly can't hurt.
I'm glad you look at it that way... if only more americans were aware of their own role maybe I wouldn't have to listen to people sobbing about 9-11...
heard this jerk saying something like:
"I don't know why anyone would wan't to do something like this to us... I guess some people are just evil"
Your lacking understanding of politics is frightening... The US would NEVER try to keep India from developing!
the fact is that they're already too busy keeping the middle-east from developing... Supporting dictatorships (saudi-arabia), destabilizing large regions (israel/palestine) and waging war (iraq) is pretty expensive. The middle-east manages to turn a profit because of the oil... India doesn't pose a threat and hasn't got enough oil.

I hate it when people say "wow, we have an unbreakable code now"
One time pads are ABSOLUTELY unbreakable...
thx :)

What if I say something wrong?
For all I know you could trace me down and sue me!

I've got a feeling bush has said something just as intelligent...

nahh... just kiddin' :)
Just for the sake of completeness... star wars is still wrong, in empty space lasers beams are invisible
