Presumably the system automatically sends "one time pads" until it determines that one has been received without eavesdropping. It then transmits the message encoded by that one-time pad. Unbreakable and very simple if the quantum detection is working.

That's the speed you need if you decide to turn off the engines and still want to leave earth's gravity. Achieving LEO is easier - you only need to go 17k mph and you can use a second rocket powered stage to help you get there. What a scramjet helps you do is use atmospheric oxygen rather than carrying your own. That saves a lot of mass.
This is an extremely interesting way to combat DRM.
It is a forgone conclusion in most people's minds that copyright will continue to be extended indefinitely. It is also the case that the Supreme Court ruled that because the copyrights are limited in duration at any given time that the continuing extensions are legal.
If DRM does not time out according to the then current copyright law isn't it in violation of the Supreme Court's ruling? Certainly the DRM software can't be sure that copyrights will be extended. Otherwise it would invalidate the arguement that the MPAA/RIAA/Disney et al used to push the extensions.
12 Volt RMS AC makes more sense. Retifying AC is easy/efficient/light compared to voltage transformation. If you need a lower voltage than 12 volts you can use a much smaller traditional transformer or use a switching circuit.
Because you are still distributing AC rather than DC you don't need the copper bars.
In fact you'd need about 2^qbits of classical computers to directly simulate an equivalent quantum computer. That is because 2^qbit states exist for quantum computer on the road to calculating the answer. With only 32 computers involved in the simulation there must be a lot of serializing going on. Keeping track of the other states must be why they have so much RAM.
I like to think of quantum computers as doing sorting rather than calculation. This is because you can give it the output to a classically irreversible and it will "sort" or "resolve" for the correct input from all of it's various multiverse incarnation.
I concur. Discovery theater looks insanely good. All their material is broadcast at 1080i. The interlacing isn't a big problem for their content as it rarely involves fast movement. 1080 lines of resolution gives that "picture window" effect that just blows you away.
Personally I'm routing for blu ray. You want to start with the highest raw capacity rather than relying on compression. Better compression can always be applied later, or included as a separate layer or side.
I'd add that plasma screens are tremendously bright to start with. Most experts will tell you to turn the brightness and contrast way down. As the panel dims you can just increase the brightness controls to compensate.
Chaos theory has nothing to say about blackjack except maybe about non random elements of a shuffle.
The "streaks" you observe are totally natural.
Chaos theory != predicting the future. It is more about characterizing randomness and determining how quickly forecasts of thing like weather fall apart to due to the compounding of various errors.
I heard the new ceramic plates were much lighter and the old stell plates were the real heavy SOBs.
In any event most army vests are designed to help with shrapnel more than anything. As you said, a small caliber, high pressure cartrige is going to go through any fibrous armor - in your case four layers.
Only plates stop those rounds and unless you want to waddle around in a suit of full ceramic plate protection will only be partial. As the story mentioned soldiers already carry 100 pounds of gear. How much more weight can a soldier "spend" on armor?
A straight vest like a cop would use would not - as a rule - stop a machine gun round, however military vests use ceramic plates that do stop rifle and machine gun rounds.
Also the protection offered by a vest isn't soley determined by whether or not a round punctures the fabric.
A vest can significantly slow down a bullet that does manage to pierce the cloth. This significantly reduces the lethality of the injury. Conversely a poorly designed vest that traps the bullet but fails to properly diffuse its kinetic energy can still cause fatal internal bleeding. Finally a vest may be pierced but has deformed the bullet enough that it causes less damage.
PS if our guys are getting hit with 5.56mm rounds it is either friendly fire our we are at war with NATO. AK-47s and their other incarnations normally use 7.62mm x 39mm ammo. It fires with a lower velocity that is a bit easier for a vest to deal with.
Supposedly those poo-germs come from minute water droplets that ejected from flushing toilets. For that reason you are better off putting your toothbrush as far away from the toilet as possible.
In the medicine cabinet is a geat place. Alternatively store it upside in a cup with Lysterine. That stuff really does kill a lot of germs. There are also toothbrush holders with integrated UV lights that kill bugs.
What if the player could only accept non-CSS content. Would it be legal then? I'd have to assume that it would be.
That same player could accept a redirected stream from a small app that decoded the CSS. Since that very small app is the only DMCA unfriendly aspect of the project you could wall it off. The kosher portion could then have legitimate focused effort.
Lots of people rip DVDs to their HDs with CSS removed as it is. An open source effort to create a high quality decoder (aka filter) would be awesome.
Space itself is expanding in this context and therefore the apparent speed isn't a violation. I guess my next question then is whether the "light cone" isn't also warping as well as space expands beneath it.
That effect would bring a greater fraction of the universe into the light cone.
I thought the exact same thing about corn starch. Sadly I also thought about using a similiar saturate for flexible body armor. Shoulda', coulda', woulda' on that patent. Oh well - I'm sure some sci-fi book gave them the idea long before I had it.
PS I wonder if Tillman would have been saved by this stuff. RIP.
That mirror is probably for focus and targetting. The wattage/m^2 is probably pretty low on the surface of that mirror and very high at the pinpoint spot on the missile.
Imagine where the US auto makers would be today if we struck a protectionist attitude in the 80s when Japanese car companies were trouncing Detriot.
I remember well the talk that US manufacturing was all going to the Japanese, blah, blah, blah. Well folks it didn't ALL go away and the parts that did go to foreign firms resulted in cheaper cars for everyone. In fact Japan moved a lot of their manufacturing TO the US not away from it. In the process we learned a lot about Japanese efficiency.
How about all the whiners find new things to do that foreigners can't and is worthwhile in todays markets. If a bonehead in some other country can do your job then maybe you weren't so great afterall. Why are you so deserving of that job? Go back to school, think of a good idea, innovate, manage foreign employees, etc...
The US would be as bad as Spain, Italy, France, Greece, etc... today if it had turtled up with protectionist policies before now.
Your gas mileage would be HORRIBLE. The initial reason for making the federal speed limit 55mph was to save fuel during the oil crisis. The safety benefit was decidedly secondary.
How did the the above comment get positive karma? Watts are a unit of POWER not energy. The stupid english version of energy in this context would be the kilowatt*hour. Anyhow watts are joules/second. Joules are the proper unit of energy.
Efficient combustion requires that the fuel reacts with oxygen under a certain amount of pressureand for a certain period of time.
Regular jets need a compession step, using turbine blades, to create an effective combustion chamber.
Ramjets operate at a speed and altitude where these turbine blades are not necessary to create the necessary pressures.
Scramjet is a meaningful designation spearate from ramjet because it covers speeds at which the air is moving too fast for combustion to run to completion before exiting the exit nossle. Scramjets solve this with various aerodynamic techniques.

DRM that doesn't time out must be illegal.

Actually a really good point. You are allowed to have disposable stages and a "ballon stage" could qualify.

Coal fired plants currently liberate more nuclear material than all the nuclear plants. They also spew loads of heavy metals that never decay.
All forms of energy production have there flaws but nuclear provokes such a viceral response in people that it never really gets considered properly.

Not necessarily. Airlines fly higher so that they can go faster with less drag. We'd probably see ramjets before we'd see scramjets.

Not true... the elasticity is mostly determined by the vests weaving. Kevlar does not stretch very much - its tensile elongation % is 2.8
Vests need to distribute the energy across the vest and elasticaity doesn't help there.
I wonder if they put a coating like rain-x on those dishes. Plastic is already pretty hydrophobic. You could also put a hood over the dish.
Just FYI - people put this stuff between the a chip and the heatsink. It definitely improves the heat transfer from the chip to the heatsink.
People aren't just spread it onto the tops of chips to magically cool them.
