Sure they use spares for the word and row lines. Almost always have. Usually use links whcih can be cut with a laser to change the connections. Some programmable styles like EPROM and E^2PROM can program the fix into special registors (assuming they themselves are working). Memory cells can be sorted into about five bins:
Good: self explanitory Bad Row/Word line: laser a fix, retest Bad Address decoder: Some rows either read and/or write simulatiously or not at all. Mostly it works, but not all bits can be used. Might be able to laser a fix. Random bad bits: Well, random
With bad decoders or too many bad rows, disable the bad part and only use 1/2 or 1/4 of the memory.
Chips with random failure have a huge market: Digital voice recorders and cheap music player. Scramble the addresses going in, so the bad bits are mixed up. It doesn't really matter if a few bits are bad in you answering machine or cheap MP3 player!
Not quite. True, electrical signals only travel at about 2/3 the speed of light. Traveling AT the speed of light only buys you about a 6 month extension of Moore's Law (yeah, I know, Moore's law is a count of transistors, not speed)

Well, assuming action-reaction, the bullet cannot have any more momentum then the gun does when it kicks against the shooter's shoulder. Therefore the impulse of the bullet hitting you cannot be more then the impulse of shooting same bullet
His formula is correct for any object outside the surface of the earth.
The effective pull of gravity decreases as you go below the surface, as the rock above you pulls UP on you. Gravity cancels out ot zero at the center of a spherical mass. We'll leave the diffy-q up to the reader

Larger feature size (especially thicker gates) and special processing can help against radiation that would cause permenant damage. For lesser events, usually only a bit will get flipped or noise is introduce onto a node. So you can build three of every critical circuit, and vote on the outputs. Majority wins.
front center, front left, front right, left, right, rear left, rear right, subwoofer. I guess 8.1 would have a rear center. >8.1 you would be sitting inside one gaint circular speaker box
BJTs and FETs become interesting as they both shrink. In FET the electrons begin to tunnel though the gate, causing a gate current. New analog FET designs look an awful like the old tried and true bipolar circuits. The two devices are becoming one-and-the-same.
They use a very fine diamond tipped band-saw to cut the wafer up to seperate all the dies (dice?). This only works with rectangular patterns. A hexagonal pattern would require a laser cutter or some such, and that kind of heat would likely damage the lattice. And thoughput would be a low.
I had a 54g Bro^h^helkin wireless router (twice) and two PCMCIA cards from CompUSA. The first router worked right away. But then I flashed the firmware into oblivion. Traded it in, then spent two weeks on the second one trying to get the wireless to work at all. It connected maybe twice, for about 30 minutes. The desktop was hardwired, at least that worked. But, it redirected me to their website 3 times. And the ad was for a Belkin 54g router! CompUSA traded me a Netgear router and cards, and it works great.
I was going though the house the other day replacing batteries in the smoke alarms. A while later I sitting on the couch, and it felt like something stung me. I jump up to find the 9V in my pocket had rubbed up next to a nickle. Hot enough to discolor the coffee table where I dropped it.
Those little things can pack a punch when used all at once. A tazer works on two 9Vs.

I was always under the impression that clean amplification had to do with a clean, stable power source
Exactly. Thing is, more car speakers are 4-ohms, which means you can only get 9 watts peaks (6V^2/4ohms, cause the speaker will be virtually grounded in the middle of the supply) or 4.5W RMS with a single 12V supply. To get more power, you need a circuit to step up the voltage. With a 42V supply, you can get 110W peak, 55w RMS. A clean DC-DC voltage circuit is a significant cost of a car amplifier. You could decrease the effective resistance of the voice coil, but building an amplifier with sufficiently low output impedence is tough.
In the first movie, when Morpheus is explaining the Matrix, he says that the machines get their energy from the humans, combined with a form of fusion.
Whether the fusion is taking place in their bodies, or the human's minds are being used as parallel processing to control reaction, or whatever, the humans are not the direct source of energy.

I forget. Are warp numbers a linear or logarithmic increase? Cause if warp 10 is 10x the speed of light, the nearest stars are still six months away.
To the first order, power increase linearly with speed, squared with voltage. P=CFV^2
