What would cause the vacuum?

By and far, most Christians look upon Mormonism as a cult, and certainly most Catholics (~1/3 of America) look upon everything non-Catholic as wrong. Only some Christians speak out against them, most won't embrace them as fellow Christians (especially because they evangelize), but undoubtedly a few do accept them.

You're right to feel confused. What would overcome the pressure pushing the blood out? And why only the jugular vein, why not a cut on the finger? I'm sure you've seen someone/yourself bleeding.

What environmental conditions are we talking about here? Desert? Steppe? Grassland? Cropland? Woodland? Montane? This is very important. Please expand on the actual end-user needs, estimated amounts of power, time of day used, stationary or mobile, etc. Does this mean no navigable waterways, or no water whatsoever? Does this mean barren, swamp, or mountain? Is water for subsistence (irrigation and/or potable) a concern? What access do they have to water for subsistence?

The danger of some cures is known, and patients can choose to be treated or not. The Renaissance physician Paracelsus said 500 years ago that: Here are a few of the many successfully controlled diseases:

By “a local walk-in store”, I think he means readily-available, over-the-counter supplies. METHOD 1 I’d suggest a square lantern battery wired to a bit of steel wool, but that might cause a little bit of molten steel (which would violate condition #2 in OP), and over-using the battery due to high current just might “over excite” it, resulting in a *ahem* “catastrophic failure” (which would violate condition #1 in OP). I’ve seen this done safely, and have done it safely myself, yet Scouting is Scouting, and we must follow the rules. (PS -- check with your Scoutmaster about this experiment, maybe he’ll approve it.) METHOD 2 Justification for this method: You're near something (say a huge forest fire), and you need to start a backfire to stop the fire from advancing. Trouble is, the blaze is so hot you can't even get close enough to it to light a stick in your hand. You think to yourself, if you could just collect all that heat in one place to get it hot enough to start a fire. Hmm… then you remember a posting on a science forum … Here’s something along the lines of unique or never-thought-of methods. Use a magnifying glass to focus the energy from a campfire onto starter material, such as paper. Use a 3-inch glass -- bigger is better. Yeah yeah, I know, it doesn’t seems unusual to start a fire with a fire, but I think no one’s ever done it this way before. METHOD 3 Justification for this method: The sun’s just set and you need to start a fire. All you have is the very warm side of a boulder or cliff (that’s facing west into the setting sun, of course) and a magnifying glass. You think to yourself, if you could just collect all that warmth in one place to get it hot enough to start a fire. Hmm… then you remember a posting on a science forum … If Method 2 seems too weak or obvious, try this niftier method. Put a flat solid object (such as a metal plate, cast iron frying pan, slate, flagstone, etc) against the fire, and use it as the source of heat energy to focus with the magnifying glass. When the stone becomes too hot to touch, it should be radiating enough energy to burn paper. I just invented this method, so I’m assuming this will work because we can sit in the sunlight okay and still start a fire with it, so a surface too hot to touch should definitely burn paper. (Caution: Never put a stone in a river/water into or near a fire. Stones can become waterlogged over time, and when heated by the fire, the water can turn into steam and cause the stone to explode.) Focal Length For an approximation of focal length for Methods 2 and 3, use the focal length found when focusing light from the campfire. The image below shows that focal length is a function of wavelength, so the infrared focal length is even longer than that for red, thus, you’ll need to increase the focal length a bit to properly focus the heat (not light) from the fire or hot object. I have no proof that this method will work, but it seems like it “should”. Try it out first before you decide to use it.

Sheer boredom! :D

IMO, the traits of the Lundehund came about through natural evolution accelerated by human intervention. I find it hard to believe that people sat down and said that they needed a dog with useful dewclaws, ears that fold shut, shoulder joints that splay, a hyperextending neck, etc, so let's breed some dogs in that direction. The special situation here being that the caves proved to be a literal "black box" in which the means by which certain dogs excelled more than others could not be humanly discerned (since obviously, humans could not even go where these dogs go). Instead, I think people noticed that some dogs came out of these caves with more puffins than other dogs, so they kept breeding the successful ones and using them and refining them. My point being that natural selection would have driven the breed toward having these traits if shipwrecked on puffin-inhabited islands without humans. Nature worked out the necessary characteristics; people simply accelerated the process.

Perhaps the Lundehund provides an excellent example of natural selection. This long webpage is worth reading: The lundehund

And part of the beauty is that the blood clots only "just enough" to close the wound. Imagine if you cut your fingertip and all the blood in your finger or hand clotted!

:D

Have you read about TOGA beamforming or about this 60GHz Design?

Thanks, ecoli, this is great! Many people suffer from "disconfirmation bias" ... they can give a million reasons why the other side is wrong instead of giving one reason why they're right. Now I know what to call it.

Electronic media is a culprit too. It can now monitor who reads its news, what they're reading, and when they're reading it. (Something papers, radio and TV can't do.) Media thinks it's catering to our concerns when it feeds us similar stuff. So, suddenly, it seems to us as though the whole world is doing cruel things to kittens if a cruelty-to-a-kitten story gets a lot of hits and media decides to scrounge through every tidbit of news to give us similar ones. I don't need commentators or media warping my perspective of reality.

Sure, but not the top man in the middle of a war (if an endless war could be said to have a "middle".) I have no doubt that McChrystal is a soldier's soldier, but he knows Clausewitz's seminal On War states that, "War is a continuation of politics by other means". I think McChrystal no longer wished to abide by it. So this as well as our troop morale and our military's global image were the reasons why he's gone. McChrystal lost the bubble, compromised our national security, and most likely extended the war which will result in unnecessary deaths. All for a couple of cheap shots at the pols.

The Chevrolet Volt is a series hybrid. I think many people want to understand what they're buying and driving. They want it to be simple, and series hybrids are the simplest. It's easy to understand that the batteries run the motor until they get low, then the gas engine kicks in and recharges the batteries. Chevy doesn't advertise the Volt as a hybrid. They describe it as an "electric car" with a range-extending gas engine. That's why you hear them advertise it goes up to 40 miles before using any gas. This follows in the footsteps of their miserable EV-1 from a decade ago, and it gets a jump on the competition for all-electric cars.

Oh. I was describing phased array. Wouldn't SBAA be the same as a phased array in that each SBAA antenna acts like an element in a phased array?

On a flat smooth road surface at highway speeds, aerodynamic drag is the major force to overcome (followed by rolling friction, etc). Drag is proportional to the square of the speed. Power is drag times speed, and thus is proportional to the cube of the speed. 40³ = 64,000 50³ = 125,000 60³ = 216,000 70³ = 343,000 So, the power required to overcome aerodynamic drag approximately doubles for every 10mph increase at highway speeds. But there's a lot of waste in ICE's and their drive trains, so only about ¼ of the power (ie, gas) consumed ever reaches the wheels. This means the gas mileage won't have this doubling/halving effect, and is much tamer, say, about 20% decrease in mpg for every 10 mph increase in speed. At low (urban) speeds, the mere running of the engine dominates the gas economy. Consider the extreme situation of a standing idle, which results in 0 mpg. It has been said that maximum mpg occurs at about 40 to 50 mph, and depends on the car, traffic/road conditions, driving habits, etc.

I get only 4 hits when I google "steerable beam antenna array". By SBAA, do you mean "phased array" radar?

A subordinate has a duty to resolve his concerns on policies and orders with his superior. He did not suffer a momentary lack of judgment; this was a long time in the making for him and his team of yes-men ... the "bang" at the end of a slow fuse. A bad apple at the top rots the barrel faster than anything else.

Right, you can understand how it electronically steer the outgoing beams with delays, but how does it receive? I'm pretty sure that the antenna's elements receive signals "at will" between transmissions, and that computers do A LOT of number crunching ... sort of like solving simultaneous equations (if you think of each element's reception as an equation), except much more complicated. This involves various pieces of data: time, frequency and location of the element. Then the variables solved for are each object's direction, distance, radial speed, tangential speed and size -- and perhaps other information.

I've used ½" clear tubing from home construction supply stores that comes wrapped on spools, so they tend to be curved and flattened, and also reinforced for durability. How long a piece would you use?

Bovine?

We can chuck a satellite into orbit that pretty much goes forever.

The player begins with a 1/3 chance of having picked the winning casket, and this reality never changes despite what the barker reveals (and the barker can always reveal an empty casket), so the other unopened casket has a 2/3 chance of winning.
