    Until they give you a grant of immunity. Then it doesn't work anymore.

    There are two kinds of immunity: Transactional immunity (witness can not ever be prosecuted for crimes related to his testimony) and Use immunity (they can't use your testimony, or any evidence they gather based on its information, against you - but if they find other evidence you're fair game.)

    Unfortunately the Supreme Court has ruled that Use Immunity is enough to extinguish the 5th Amendment right and federal prosecutors rarely offer Transactional. Some states have more stringent laws, constitutions, or constitutional interpretations and Transactional immunity must be offered before their courts may compel testimony.

    Of course prosecution is not the only life risk for a witness. I know of at least one person, here in the disarmed-citizen utopia of California who has stated an intent to "not have seen anything" unless granted a perpetual concealed carry license.

    they all start with some common underlying mamallian hearing genes and then they tweak them to develop echolocation.

    Actually, a lot of animals that aren't credited with using echolocation actually use a variation of it: Sounds from their own motion (such as footsteps) create echoes, which their hearing system processes into a map of nearby objects.

    People, for instance, do this. That's why you can "feel" the nearness of walls and objects in the room (especially those near or immediately behind you) without looking, when you're moving.

    There's at least one recorded instance of a totally blind child who learned to ride a bicycle and avoid objects, by making clicking sounds with his mouth to provide excitation for this system.

    (The hearing system of things like mammals is evolved from the lateral line of fish - which both detects other nearby fish by direction-finding on the sound from their muscle twitches and other sound-reflecting objects by detecting the echoes of muscle twitches of the fish doing the listening. (A flat surface, for instance, would produce an acoustic mirror image of the fish every time it twitched, identifying the return as an echo of the fish itself.) It would not surprise me if the processing for echolocation in other animals is just a revival or slight remapping of this same mechanism.)

    please, please ... pass on this advice to a Progressive

    While you're at it, point out that a lot of their prescriptions INCREASE risk while purporting to reduce it. It's doubly annoying when they work so hard, throwing money, effort, and restrictive laws into trying to solve a problem when the effort and sacrifice actually makes it worse, in a positive feedback loop.

    Progressives have no monopoly on this, either. Neocons, consdrvatives, and even Libertarians do it as well. It's easy for all to do things to attack a problem and not see that the indirect effects of the effort cause more harm (even in terms of the problem being attacked) than the first-order effects help.

    Some examples:

      - Gun control: Private ownership and carrying of guns REDUCES crime, violence, victimization, and death, while citizen disarmament increases them.

      - Attempts to police the world produce "blowback", creating new and/or motivating existing enemies, increasing, rather than decreasing, the risk and costs to the US from war.

      - Drug prohibition creates more drug use and criminal enterprises, rather than reducing drug use, and harms the drug users more than the drugs do. Its component programs often have counterproductive pathologies of their own. One example is the D.A.R.E. program, which attempts to use peer pressure to encourage kids to ignore peer pressure, and has been shown to increase drug use.

      - Grabbing advances to any program, rather than considering whether achieving goals in the wrong order makes things worse rather than better. (A Libertarian example: They want both open borders and an end to government wealth distribution such as welfare programs. Unfortunately, opening the borders first leads to an influx of social program dependents, making the overall problem worse (and increasing the voting block to preserve and expand the programs), when fixing or eliminating the programs first would remove most of the downsides to opening the borders later.)

    Variation by a factor of 2.5? That's VERY noisy data to use for the extrapolation of rates. How few samples and what level of noise do they have that they can't come up with better error margins?

    This rate may be increasing. Since 1992, new methods of satellite altimetry (the measurement of elevation or altitude) indicate a rate of rise of 3 millimeters (0.12 inches) per year.

    And with noisy data you occasionally get an outlier on one end or the other. Of course if you want to produce panic you treat the biggest excursion as if it's the average, and extrapolate it out for a century. But even if you do that you're talking a whole 12 inches sea rise in a CENTURY.

    Censorship never slows the spread of word where a disease is concerned, it only adds rumor into the mix, to create confusion.

    Sure it does. A prime example is the 1918 Influenza Pandemic and president Wilson's reaction to it.

    Wilson and his administration saw news of the disease as promoting a public response that would hamper the war effort, and reporting it to be treason. So he had the government suppress the news and spread disinformation. Among the effects:

      - The disease had shown up in one military camp. The commanding officer wanted to quarantine the camp to keep it from spreading throughout the military and the country. But his orders were countermanded from above. Result: Sick and incubating soldiers were shipped all over the country, spreading the disease.

      - Disinformation about the nature of the disease, and how to treat it, was disseminated, using the Public Relations resources of the government, which drowned out more accurate statements from the medical community and others. This amounted to a set of government-created and broadly propagated health frauds, some of which persist today, causing those who believe them to waste money and impair their health. Among them is the theory of "autointoxication": that flu (or other disease) symptoms are the result of toxins produced by intestinal flora (if retained too long) and a resulting illusory need for "regularity" - having daily bowel movements at roughly the same time of day. To this day this theory results in laxative overuse and sometimes addiction, vitamin deficiencies, intestinal irritation, and delays in seeking medical attention when it is needed for a real illness.

    So censorship CAN slow, or even suppress, the spread of word where a disease is concerned, bury the truth, and stop appropriate handling of a disease.

  15. Re:Since when are digital projectors thousands? on The Death of the American Drive-in · · Score: 1

    I don't think it is "inverse square from the projector to the screen and inverse square back". I think the inverse-square law for light is radiation from a point source, i.e. it describes the drop-off in illumination as the light spreads out, rather than attenuation per se.

    The inverse square law is related to light spreading out from a point source. If you have an infinite line source you get inverse first-power. For an infinite plane source it doesn't get dimmer at all.

    (That's why the hubble expansion of the starfield and the resulting red shift is important: If the stars were all hanging in there rather than receeding, just about any way you looked you'd see the un-red-shifted surface of a star, which would make your black-body temperature about the average solar surface temperature, rather than a compromise between 4 degrees absolute plus the heating from the sun and the radiant tempreature of the Earth's surface, atmosphere and clouds.)

    However, a movie projector is a close approximation to a point source located a few inches behind the projection lens aperture. So it's inverse-square going out to produce a given brightness on any patch of screen.

    For any given patch of the screen the light coming back is also inverse-square. If the distant screen were the same size as the close one it would be inverse-fourth-power, as I claimed.

    However, the screen in a drive-in is a lot larger than the screen in a theater. Any given retina cell gets the light from the same solid angle regardless of the distance to the screen. This goes up with the square of the distance, exactly canceling the inverse square of the light coming back (assuming both screens use coatings with about the same optical scattering properties). So the effective rule is actually inverse-square, not inverse-fourth-power.

    (Inverse fourth-power DOES apply to radar, where the target is the same size regardless of distance and thus doesn't do the cancellation of the inverse-square term on the returning echo.)

    Have people been resuscitated after say, 30 mins or even an hour, and managed to have their brain functions relatively intact?

    Absolutely. Look up "Mammalian Diving Reflex".

    Brain damage from short-term clinical death happens primarily after revival. The valves routing blood to the parts of the brain that need it stick in the state they were in when the oxygen finally failed.

    Muscles contract with stored energy and require metabolism to relax. "Valve off" is contracted, so when blood flow and oxygen is restored, the valves for regions of the brain that were turned down don't get oxygen and can't reopen - and without the blood flow they can't get oxygen, in a viscous circle. Raising the blood pressure to try to force them just blows the vessels, causing a stroke. The
    nerves die over a half hour to an hour (and kill each other off through glutamate cascade, as dying nerves release glutamate that causes others to fire, deplete their remaining energy reserves, and die in turn.

    Mammals, though, have a reflex related to deep diving. When diving deep, the increased pressure increases the partial pressure of oxygen, keeping things running until most of the oxygen is used up. Then coming back back up lowers the pressure further and can leaver the brain oxygen starved for long enough to produce the "valves stuck" phenomenon. To prevent this, mammals have the following reflex: When oxygen is running out AND the body (I think it's the back of the neck) is cold, the valves all open up, so any that get stuck are in the open position. Once oxygen is restored the blood flows, the nerves survive, the muscle gets repowered, and all is well - if thing hadn't been shut down long enough that too many cells died meanwhile.

    This was discovered when some victims of drowning in cold water recovered just fine, with no brain damage, after half an hour or more of clinical death. I think the time before damage sets in is something between 25 and 45 minutes.

    I don't know how CI's current protocols work. But ALCOR's are designed to include activating the diving reflex, if possible, so the brain's valves stick in the open position.

    (This is more to encourage better perfusion of cryoprotectants than to try to make the brain restartable: As of the last time I looked the thought was that brains preserved - even by the best techniques available at the time - would require rebuilding by nanotechnology, so the idea was to preserve as much as possible of whatever might encode memory and personality.)

    It most certainly does not - where did you hear such a thing? There is a steady decline in scores on IQ tests after age 20 or so.

    That's what they thought for decades - that intelligence ramped up about linearly until the late teens to early twenties, kneed over, and declined about linearly (though more slowly) until death.

    But after IQ tests had been used for a few decades there was a substantial population who had taken IQ tests several times in their lives. Somebody got the bright idea to track the trajectory of individuals as they aged, rather than using different cohorts for each age's scoring, which conflates IQ changes due to aging with IQ difference between generational cohorts.

    The results were surprising, and very clear.

    The trajectory for individuals was the linear ramp up, knee over, and a gradual, linear, change for the rest of life. But the ramp went UP (about a third as fast as they had previously thought it went DOWN). And it was far more linear than the previous estimates.

    Turns out the apparent decline with age was due to a much larger trend of higher IQ scores with later cohorts. Much of psych research since this work has been looking for the causes of the lower IQ in earlier generations: Candidates include improved nutrition (especially eliminating dietary deficiences), better treatments for or prevention of childhood diseases, and so on, better education (in what scores on IQ tests), etc. (One big one turned out to be the elimination of thyroid deficiency by iodizing salt.)

    Detailed examination of the effect shows that the high scores aren't rising substantially, but that the lower scores are coming up to approach them - another sign that it was mostly a matter of eliminating brain-harming pathologies rather than a general increase in IQ.

    This has been known for decades. Where are you getting the old model? Is it still being taught, after all this time? Or did you see it long ago and miss the later breakthroughs?
