Oh, come on! One pole is very, very wet, and the other is extremely remote and cold and gets very experienced pilots only.
In this context being within about 30 degrees of (magnetic) latitude of the (magnetic) pole qualifies as "close". We're Nearly 40 degrees from the pole, but I still re-calibrate my compass every couple of years (it has an adjustment for that ; why would you buy a compass that didn't have that?), and there are over 100 square miles of my local navigation area (in several non-contiguous areas) where relying on the compass in 100m visibility conditions could kill you if you got it right. And would also kill you if you got it wrong. So, you use your map, and only use your compass to compare (eg) the angle difference between rock joints and hillside slope.
Heck, Alpha Beta Gamma, etc would be just as useful in this world of GPS.
I can't remember the name of the band, but there's a good piece of heavy music that starts with the lyrics "747 coming down in the night / no power, no runway lights". Which is a pretty unlikely situation - both the multiple power systems on the aircraft failing, and those on the ground. But what the fuck? The exact point of having a MAGNETIC compass as a fallback from all other systems is that it requires precisely (not approximately) zero external systems, including not more than zero external power supplies, computational dependencies, or anything else. It's still vulnerable to sabotage - all aircraft are - but not external failure.
Not all aircraft have GPS. Not all commercial aircraft have GPS. Not all GPS systems work all the time. No GPS system is guaranteed to work all the time. So aircraft designs will continue to incorporate magnetic compasses for the foreseeable future, regardless of what you think about the reliability of the systems.
create a surrogate key that will be constant for all time
Thinking as a geologist, which I do, because I am, Neither your geographic location nor orientation is particularly stable - in a mere 10,000 years every airport location in the USA (outside Hawaii, sorry) will have moved around a runway spacing further west (~100m), fucking up anything based on GPS locations.
But the paint won't last anything like that long ; nor will the tarmac. From my local, fairly busy (around 50 flights/ runway/ day) airport, the paint will last some years, and the tarmac will need significant patching about once a decade. Which renders the comments about this being "additional" spending pretty moot. If you've got to relay the tarmac (to repair frost damage and correct for ground settlement - most airbases are on old lakes or river plains, which are not the most stable of soils) every decade or so, then the cost of painting different numbers on the new surfaces, and replacing the signs you had to rip up to get the tarmac-chewers and tarmac-spreaders into place, all become just another part of the cost of maintenance.
If you have Slashdot Advertising (I haven't seen that since some years before I started to use NoScript or even AdBlock; I guess there is still some advertising somewhere), then perhaps Amazon are bugger buyers than BMW. Or... there is some other reason. But it's gouging nonetheless.
I actually brought several things from Amazon last year. Three books, one new, as I recall. Despite being told to make it one delivery, it still required three visits to the post office to collect. Explain to me again the reason for this "Prime" crock?
Yup, classic insurance fraud. Many cars in Russia have dash cams for this very phenomenon.
Bollocks, to be polite. The (relatively) high usage of dashcams in Russia is pretty much fuck all to do with insurance claims (since tens of percent of vehicles don't have insurance anyway, compared to singles of percent in more efficiently-regulated countries) and everything to do with avoiding "squeeze" from traffic cops : "Well, citizen, my colleague and I, with guns on our hips, are sure that we saw you jumping that red light, which would mean a 500 Ruble fine and several days off work in court if we start filling out this form. Or we can develop selective amnesia for 100 Ruble. Your choice."
It's by no means unique to Russia, and if anything it has been decreasing over the last few years in response to the frequency of dashcam use and the decrease in on-street corruption in response to Putin's power tightening.
Do AC's even think before writing shit these days?
Makes me feel real good about the forced updates of Windows 10
Makes me feel ecstatic about it. But then, I don't use Windows. I might have to get a Windows machine for work in the near future (oh, bollocks!) so I might have to worry about it. But until then, it's an SEP.
we still don't allow people to shoot guns randomly so long as they're not aiming at someone.
This sounds like you know what the NRA's next gun law removal campaign is going to be. "Got a gun? Now you'll be able to walk down the street firing off as long as you don't actually aim at someone!" If I were wanting to do this, I'd protect myself by not wearing my short-sightedness glasses. Then I could prove that I couldn't see anyone I actually hit.
who prescribed another antibiotic which cleared it up almost immediately (like the next day thankfully), and hilariously ginger-ale as apparently even after only a couple of days I was severely dehydrated
The ginger ale isn't in the least bit amusing. It - and variants - are SOP for dealing with significant dehydration where the patient is otherwise not suspected to have gut damage and is unlikely to lose consciousness unattended. Clearly, you want to get fluids into the patient ASAP.
Now, the next bit is going to be heretical for those religiously sucking the nipple of their bottle of Perrier to "stave off dehydration".
Water isn't much good for curing dehydration. Give most people a couple of litres of water and instructions to "drink that as soon as possible", and you're more likely than not to have puke on the floor, and still need to get several litres of water inside the patient. A WOMBAT. Do the same with orange juice, and as like as not you'll get over a litre of water (plus various salts and minerals) into the patients blood stream per hour. your quack prefers ginger ale to orange juice ; "meh".
Of course, if your patient has (e.g.) a perforated gut, then you're making the problem worse. you do need to do your diagnosis first. I encountered this in the mountain rescue context with someone down through hypothermia or exhaustion, but no physical damage. With good patient management you can often get them to walk themselves back to safety. And the OJ is a useful tool in that.
The property you're looking for is thixotropy, converse of this material's "dilatent" property. There are lots of examples, and millions of people dead over the millennia due to the property. A significant number of clay minerals have this property. Pile them together with lumps of lava on a volcano then pile more rocks on top (increasing the stress on the clay between the rocks) during an eruption, and eventually the clay will begin to move. When it will become less viscous, resisting the stress less, so moving faster. That's a feedback loop. The resulting rock avalanche is bad news for people downhill.
No, seriously? A time clock covers pretty much all usage cases, if you're in the house every night. Otherwise, you use the "frost protect" setting and put any temperature sensitive plants in one room with a plant-appropriate setting.
Internet connected thermostat - what a fucking stupid idea. Regardless of the apparently abysmally implemented security.
How the hell do they figure out that this girl's name was "Sunrise" when
Oh for fucks sake. Did you actually read the fucking paper? That was a name given to the body by the present-day occupants. They could just as well have called it "Joe Bloggs", "Jane Doe", or "Harley Featherstonehaugh pronounced Fish, the Twenty Third".
No Longer an AC
If that' the most substantial comment you can come up with, then it was a bit of a waste of effort, wasn't it?
It's widely believed Americas was settled by people's crossing the Bering Straights and migrating out. If that is the case then why are the seemingly more advanced/developed civilizations located in central or south America. It seems counter intuitive that the further away regions are more developed.
Firstly, the peopling of the Americas took place between approximately 15500 years ago and 14800 years BP (Before Present, "Present" being 1950, when absolute archaeological dating was just getting started). The Monte Verde site in Chile is quite securely dated to 14800 BP ; 15500 is an educated guess. However, this fossil is from 11500 years BP, over 3000 years later. During those 3000 years the Americas were populated to the maximal density their technologies could support.
Sometime between 11500 BP and today several things happened - (p) the last descendent of the parents of this fossil died without issue ; (tilde) agriculture was developed based on maize ; (Prince-squiggle) squashes and potatoes were developed too ; (foo) murderous fornicators arrived on large canoes from the east ; (bar) this fossil was dug up. (Arrange p, tilde, Prince-squiggle and foo how you like; bar was the last of the sequence. Probably.)
The development of more complex, more urbanised civilisations in central and southern America most likely reflects the calorific yields of their food crops. More calories produced per man-day means more food to support "specialists" (non-farmers) to invent and/ or build "civilisation".
but if we're going to respect any religious beliefs
Your question contains the answer : just don't respect any beliefs. If you want respect for a belief, provide some tangible evidence for it. Do a miracle! Raise a dead person. Turn whine into water. Otherwise, take the religious idea and bury it's fetid corpse under the garden hedge along with the last three cats.
Yet the Celtic languages of Britain and Ireland share several key grammatical features with Semitic languages. Perhaps these features were shared alongside the mixture of genes.
Given the documented evidence (written, genetic, and in the details of isotopic make up of minerals like tin ore) of repeated contact between the Phonecians and the Cornubians from early in the "Bronze Age", this should surprise no one who has thought about it for a second. Therefore anyone expressing such surprise can safely be assumed to have not thought about the subject for a second. They're probably parroting something they've read or heard without understanding.
Incidentally, everyone in between Ireland and the Levant would have had a bit of sideswipe genetic effect too. Sailors being sailors, and merchants having both valuable goods and a knowledge of what people want. That's if they didn't indulge in a bit of slave trading on the way. Buy 'em; fuck 'em on the boat; if their belly swells, sell 'em where you can get a good price (or trade for another a bed warmer) for 'em; lather, rinse, repeat.
Bzzzzt! Genetics exam failed. Go back and re-do your genetics course.
During meiosis (chromosome reductive cell division; not regular cell division - that's mitotis), each chromosome splits into two haves, then split at number of points within each chromosome ("crossovers") . The segments between crossover points then randomly switch to one daughter chromosome copy and to another. If both alleles of a gene in a crossover segment are the same, then you'll get indistinguishable products, but otherwise one allele will go to one pair of product gametes, and the other will go into the other pair of gametes. That is essentially random. It's why we have sex. Neither eggs nor sperm are identical.
There are 26 chromosomes, so even without crossovers there are about 67 million possible outcome eggs from one genome, even without the additional within-chromosome crossover points. Most of them will be broadly similar (because most alleles have very similar functions in either sequence), but it's what makes the difference between, for example, your immune system's behaviour and your identical twin sister's immune system.
The same argument applies to sperm, of course. And a larger environmental effect, since egg formation takes place while the foetus is buffered by the mother's immune system, while most men go on making sperm until pretty close to death.
not so much whether stuff is switched on or off but how much it is switched on or off, what they used to call junk DNA.
That would never have been called junk DNA. It would have been called "regulatory DNA". Not even non-coding DAN (since it codes for a ribosome that regulates the action of other genes by binding to a locus which either prevents or promotes initiation of expression of that gene.
I don't know what your genetics text book was, but it wasn't a very good one.
Why is he only banning one class of recording devices? There are whole companies dedicated to producing (for an example) audio recording devices buried inside a (working) pen or fag lighter. Nothing suspicious about carrying one, and with the density of flash storage these days, you'd switch it on as you leave your office and use it as a pen (fag lighter) while recording the President's self-incrimination.
Or maybe the senior White House staff (what do the Americans call it - the "executive branch"?) is populated by fucking morons without two brain cells to rub together between the lot of them. And their professional permanent support staff (civil servants, or whatever the EN_US term is) are passing them rope with well-tied knots in it and letting them attach it to the gallows themselves.
The traditional revival technique for frozen animals was the application of a red hot teaspoon to the chest of the resuscitee. Some people didn't think that was nice - or didn't like the smell of burned flesh - and so turned to the microwave oven.
Try doing your BOSIET - Basic Offshore Survival Immersion & Emergency Training - one day (I've got to have my 7th or 8th repeat in the next couple of months). Same shit, including being thrown into a convenient cold sea for an hour before being given the liferaft. Which you have to inflate, right and enter from the water in order to move onto the more challenging bits of the programme. After that, the blackout fire room, finding and donning your respirator in the dark, smoke and flames is a relaxing after noon. Then the Helicopter Underwater Escape Test.
It's an industry standard. Fail it, lose your job. Most years, someone dies per testing centre.
The Canadian and US coast guards did a bunch of experiments with volunteers (and proper medical and dive support) in moderately cold water.
Pretty much useless window dressing. The results were already known before the experiments were done because the experiments had already been done. In 1939 to 1940, the Third Reich were having lots of planes shot down into the cool (rarely above 10degC), and their expensive and valuable pilots were dieing after survivable parachute landings on water. So they did a considerable number of experiments on disposable, cheap people in Dachau Concentration Camp. Pretty much all our basic knowledge of the effects of hypothermia on humans stems from these experiments and the dozens or hundreds of people killed in the programme.
Most navies and/ or air forces with non-tropical operations have repeated such experiments with volunteers, who don't die because the the people at Dachau did die, and their deaths were recorded in considerable detail. Now all that is being done is design validation where you shove a thermometer up the arse of a volunteer, put them into the test suit, throw them into the water, and demonstrate that this design achieves (for an example) the Canadian-Norwegian standard of less than 2 degrees of core temperature drop in water of 2degC after 6 hours immersion. The Dachau data indicates that after more than 2degC of core temperature drop, the person is unlikely to be able to help themselves, e.g. by maintaining spray shield in position, or climbing a boarding net into a high-sided vessel.
Not a pretty piece of science, but science none the less.
ceoyoyo ( 59147 ) : But sharks are basically cold blooded,
angel'o'sphere ( 80593 ) : Big sharks are actually warm blooded (Great white, Tiger sharks and Mongo etc.)
This is why there is technical terminology, which doesn't include "cold blooded" and "warm blooded".
The terms you're looking for are "poikilotherm" and "homeotherm." Wiki gives these definitions : "A poikilotherm is an animal whose internal temperature varies considerably. It is the opposite of a homeotherm, an animal which maintains thermal homeostasis."
Some organisms achieve homeothermy (constant internal temperature) by metabolic modification - mammals and birds being the classic examples. Some achieve homeothermy by living in or on other organisms - the several trillion bacteria in your gut and the other trillion on your skin are examples. Some achieve homeothermy by being massive - their normal metabolism being sufficient that internal temperature rises to radiate the heat through a relatively limited area of skin (adult dinosaurs above about 5m length probably did this, regardless of their metabolic status, but much affected by their shape and/ or feathering). Some achieve temporary homeothermy by behaviour - the classic being a lizard basking in the sun before hunting.
You're both right, to a degree. There is little evidence of metabolic adaptations in sharks to produce heat without muscular movement. But the larger sharks can achieve functional homeothermy by dint of their size and constant motion generating sufficient heat that they have an elevated internal temperature at most times.
(Some of us grew up with the arguments over dinosaur poikilthermy or homeothermy, and the distinction was the topic of discussion over Sunday lunch. If you lived in the right sort of home.)
I've no problem with flatulence jokes (though I've still never heard that one). But how fucking sad it is that someone wrote it up for Wiki. Talk about "first, wash your dog."
