While I can imagine a suit like this working, I also have questions about its effectiveness. A suit like this wouldn't protect a human from rapid acceleration/deceleration. Our brains are actually suspended in a fluid, so too much acceleration/deceleration would cause the brains to hit the inside of the skull, causing a concussion. If the force is big enough this could cause a knockout or even brain damage or death. I wouldn't jump of a cliff with one of these!
Aparently they use digital light processing, as stated by an AC in this thread. Too bad, I could already imagine geek clubs devoted to tuning their TV lasers:P
Actually I sometimes use &array[0], even though I'm fully aware that it's the same as array. The reason is usually symmetry, i.e. when using other indexes of that array in the same line, or nearby in similar context. It's all about code readability, which makes it easier to find bugs and maintain the code.
The new laser tv display is different because each pixel is created by light from a tunable laser
I strongly doubt that. The laser frequency depends mostly on the laser medium. This is why most tunable lasers are dye lasers, because here they can replace the dye (solution) with a different one that gives a different laser frequency. And you can't replace the dye within the few ms that it takes to light a pixel. Probably they use 3 laser diodes here in primary colors in to create an RGB image on a white phosphor screen. The lasers can be modulated in an analogue way, so it will have better intensity dynamics than LCD. Also, the pixels will be sharper, because you don't need 3 phosphor colors and a mask (one pixel instead of RGB pixels). Using mirrors, they can fold the path of the screen and create thin TVs.
Yes, I concede, my gut and I were wrong. I was thinking that general relativistic effects (i.e. frame dragging) would cause an extra shift. In theory they do, but it seems that the extra shift would be practically unmeasurable.
Intreaguing question. Didn't consider the blueshift (mod me down:P).
My gut feeling says that because the light trajectory was altered by gravity, there must be some effect on it's spectrum. But I would have to do some difficult calculations to see if my gut is right (it is, after all, a very dumb organ). Need more coffee...
Nice try:P
Of course, since background radiation are photons which move at the speed of light, they have no rest mass, and their mass equivalent doesn't interact gravitationally with other masses. Also, measurements show that there is very little variation in cosmic background radiation, meaning that these photons don't clump together, and thus don't interact gravitationally.
True, but by the time the cdr/w fades (provided you don't leave in in direct sunlight or a hot, humid place), those manuals will be outdated anyway. Data on a cdr/w should last a few years. And paper is also volatile if you light a match to it:P
I regularly print out all the important mails (both received and sent) because I can't trust that the electronic copies will remain available in a year or so.
Of course, you could also just copy the electronic versions to some safe place (cdr/w or something)...
If I use any GPL code in my application, even one line, I have to release my application under the GPL license.
Not exactly. It's conceivable that you accidentally include a line of GPL code in your own work (maybe because a third party presented the GPL code as BSD code). Distributing binaries based on this code violate the GPL, thereby revoking all rights given by the GPL for this code and for those binaries. Meaning you or others can no longer distribute your binaries. To fix this, you either change everything to GPL or you remove the violating GPL code and replace it with your own. This second option is also used when tainted code is found in GPL code (i.e. the reverse situation).
Really? I thought the whole point of relativity was that you never see photons going faster than C regardless of circumstance.
I think you misunderstand the parent (and special relativity). the observer sees each photon move at speed c away from him. He sees they're moving away from each other, and thus concludes that they are moving at 2c from each other. If you do the math with Einstein's velocity addition_formula then you'll see that if two observers are moving at lighspeed toward (-c) or away from (+c) a third observer, they will measure each others speed as respectively -c or +c, never more.
True, but since the wire is not directly connected to the transmitter output coil, and the wire length is not matched with the wavelength (lambda/2 of about 0.07-0.18m doesn't match a wire of about 1m very well), the power radiated by the wire is going to be minimal. Also radiation is omnidirectional and the RF power is spread over the length of the wire. The beads are good to prevent EMI though, which would elevate the noise floor.

Commenting on spelling? You must be knew here...

Actually, most of the arctic (northern) icecap lays in seawater. But you're right about the anarctic one.
Hmmm... That reminds me of a certain Futurama episode...

Damn it! Now I have dead pixels in my screen!
So basically humans have about 98 kBytes worth of memory :P
Depending on the WM, I figure the names would be Girefox, Kirefox, and Xirefox :P

Probably not. Gravitational lensing would cause a noticible shift in the star's spectrum.

What do you mean I can't drink it ?!!! *** Me takes giant sip and swallows cubic lightsecond of space booze *** Aaarghh!!! I'm BLIND !!!
Lol. Termites evolved from roaches by the way.
