    The people who do such things to prisoners aren't cops, or soldiers, or any kind of public servant. They're criminals, and because of their abuse of power, should be treated even more harshly than we treat serial killers, pedophiles, and other such scum.

    They're also human, and as such experience the same emotion, anger and confusion that other humans experience. You would think that your USAF experience would have included some study of the "fog of war" or effects of high stress situations on rational thought. Wouldn't it be interesting if the cops/soldiers in question were convinced that they too were dealing with criminals, and that those criminals "should be treated even more harshly than we treat serial killers, pedophiles, and other such scum." Would you, as a human, abuse your power if you had the ability to "reach out and touch" these partcular soldiers and police who obviously disgust you? I think you would, based on your pre-trial/pre-conviction suggestion of severe punishment.... Can't say I haven't thought those thoughts though...

    I'm assuming that they mean 100 times as much linear force per unit mass.

    If I remember correclty, SMA force capabilities are often posted as "block force," which is the peak force (Newtons) that can be exterted by the SMA. There is typically no (very little) displacement of the ends of the SMA wire during this test (no strain of the SMA wire). Another parameter of interest is the maximum strain or throw of the SMA with no load (called the "free displacement"). I think a few percent of the total SMA length is typical, but I'd have to burn calories to check that....

    Obviously a huge block force exerted over a very small distance is not as useful as a skeletal muscle-like replacement (think piezo-ceramics). The SMA actuators have a much larger free strain, and typically smaller block force and MUCH lower bandwidth capability (order of about ~1-Hz with just passive convection cooling) than piezos (kHz). Heating them up is as simple as passing current through them. Cooling them down just as quickly, as you mentioned, is not possible by simple convection cooling to the ambient air.

    I suppose that there is always the possiblity of using a more active temperature regulation system. Or, as another poster suggested, using the actuators in opposing pairs would help stretch out the "relaxed" SMA.

    how can REALLY low noise impair your hearing? Be specific, make sure you talk about the decibel level at which that REALLY low noise can impair your hearing.

    I am not an acoustics expert, but I did stay at a Holiday Inn last night. So I'll give it a try. Let's assume that by "low" the poster means low amplitude, and not low frequency. With ordinary headphones (and speakers) there is usually a passage between the driven surface of the "actuator" of the speaker (cone, piezo, film, whatever) and "the world" outside the ear canal. As the surface moves, it causes pressure waves which are free to pass to the ear of the listener, but also to the rest of the world through holes, foam, whatever. It is an "escape route" for really high pressure air-- an alternate path for energy to travel.

    Think of it this way: Assume air is incompressible (which it isn't, but bear with me.) If you sent a REEEAAALLYYY slow sine wave (below hearing threshold) to a speaker, the motion of the actuating surface would displace the air near it according to its amplitude. If you have an air permeable membrane or a hole or just empty atmophere, the displaced/replaced air would simply spill in the atmosphere. You would not detect any noise becuse there would be a very small pressure difference over time at your ear drum.

    Now, with an air-tight ear-bud, there is no escape route from the ear canal and the atmosphere. It is a sealed system, with an actuator on one end, and your flexible ear drum on the other end. If you again consider air as incompressible (or better, approximately incompressible with respect to the flexibility of your ear drum and the driving forces), as you actuate the speaker in the ear bud, your ear drum will have to deflect by an amount that (appoximately) conserves the volume between the speaker and your ear drum. Consider that your ear drum likes to "hear" pressure waves traveling through the air. It does not like to be driven directly, which is closer to what the really tightly fitting sealed ear-buds look like they do.

    Yeah, it's a gross simplification of the problem, and the assumptions will make engineers/scientists cringe. If you want to "see" what I am talking about, stretch latex glove or flexible membrane over the opening of a plastic bottle. Now squeeze the bottle (low amplitude). You are the actuator, actuating the bottle (speaker), causing the latex "ear-drum" to deflect slightly. Now, poke a few pinholes in the bottle and repeat. Now a few more holes. And a few more. Note the dependence on frequency and amplitude (pressure). Compare and contrast your results with your pre-lab calculations. Repeat the experiment using water instead of air in the bottle. Lab reports are due in my office by Friday....

    As for realistic quantitative estimates of what would cause damage, I have none. However, if as in my explanation you consider air as incompressible, and assume no dissipative losses, then the power output from the ear-bud would be the same as the power received by the ear-drum. The power attenuation would be 0-dB. If you have a "leak" somewhere, and the system is capable of bleeding pressure to the atmosphere (for compressible or incompressible air), the attenuation would be >0-db. Watt for watt, sealed air buds will deliver more power to you eardrums than regular non-form-fitting ear-phones or a speaker, regardless of the frequency or amplitude.

    I must have missed something in graduate school. When was it proved that there is no God?

    The existence of god is still up for debate; nothing has been proven. It's a gross simplification, but I am going to lump all of the posters into two groups: The first is trying to define what "god" is. The other group is trying to define what "god" is not. Feel free to draw a Venn diagram. So there is a boundary that separates what god is and is not. Some folks (first group) have faith that god is defined to be consistent with their beliefs. So from their perspective, religion being what it is (slow), the boundary of what god is (or religion, or whatever) does not change much with time.

    However, much of the other group sees the same boundary change rapidly-- they have learned what god is not, through science, experimentation, experience, etc. For example: Lightning and thunder are not really god bowling in heaven, though not too long ago, it could easily "correctly" interpreted as a sign from god. So, yeah. God is not lightning. (Or rather, lightning is not god.)

    The problem here is that many people (from one perspective or from both-- the religions scientist, maybe?) see a contradiction, and it agitates them.

    Personally, I think the hard-core ID side needs to get a grip, and quit thinking that science is chipping away at the rigid walls of religion. Think of it this way: The more often we can show something to NOT be supernatural or devine, the more incredible the unexplainable becomes. With science, your god is not getting smaller, but bigger, and much more complex.

As you mention, your interest in the text would be an appreciation of the work as a creative product, not as a "cookbook for life." But there *are* books that people live-and-die by. And there are people who (by mental defect or fanaticism or whatever) will interpret and value the book in ways that defy common sense and logic. I am inclined to think that monitoring books is a long-shot, a waste of time, and unethical. But the people that they really want to catch are well outside of a few sigma of the "standard" person, which makes them easy to isolate in the event that they cross some threshold.

Example: Where would you start looking for child molesters? Now, obviously, most people are NOT child molesters.
