That's why courts have immunity. afaik, once granted immunity, you must provide testimony/evidence or you can be held in contempt.

    It has always been that search engines start to suck after a while, i suppose due to tailored sites. That is why we need many different search engines: to keep people from being able to reck any single site. When google first came about I think they even addressed the issue, claiming to change their algorithm every so often as whatever's current gets taken advantage of. Before the bottom feeders, google's results were spectacular. Hopefully either google will change their algorithm (doesn't have to be 'better' necessarily, just 'different') or something new will come around and we'll all just use that.

    It wouldn't be boring to mention. There is a filmmaking device invented for just this sort of thing. It's called a montage.

    They also make a lot of unproven conclusions based on evidence shown, but that makes sense since they're not actual scientists/engineers (though they should've included at least one PE on their staff). The 'suction from sinking ships' comes to mind: their experiment did not take into account effects of scale. e.g. their pool model, the tugboat, and a real ocean liner would all have different reynolds numbers, their experiments should've been altered to take this into account.

    The chicken gun was a particularly bad example of this as the high-speed video showed exactly what they were claiming to disprove: the frozen chicken impact took place over a shorter time period and over a smaller area --- it did not "spread out as much" --- Since they noted that the total impulse was the same whether frozen or not, the conclusion is that the pressure exerted on a real window would've been greater for the frozen chicken. Whether the frozen chicken would break the window and the thawed chicken would not is a matter for more trials, but their experiment showed that it was indeed possible.

    Also, they should consider more than one myth-historian. I vaguely remember at least one episode in which the myth as I knew it (and as found in snopes) was not the same as the one she described. Coincidentally, her version was easier to disprove. Certainly, being myths, there are more than one version out there, but i would expect a myth-historian to know of the more popular versions and at least have heard of snopes.

    That being said, the show is good. It's fun to watch and makes people think about physics. It could be great---in addition to thinking about physics they could have good physics, by doing exactly what they do now, but with real scientists to guide the experiments. I expect that either Jamie & Adam are too narcisistic to allow additional experts or ---far more likely---Discovery doesn't want to spend much more money on this than they do on "remarkeably homogenous chopper-of-the-week" (or is that "the learning channel" I keep getting them mixed up because the programming has slipped so far into MTV land)

    Ok, back of the envelope time.

    Total electrical power used by people on the earth:
    ~14 trillion kwh
    (assume all of this is used to do something in a building and that no other energy is used by buildings and that all electric power is generated by non-solar means: no solar, hydro, or wind power)

    Total people on the earth:
    ~6.5 billion

    total: 629 GW

    Total insolation:
    2*pi*(6378 km)^2 * 1400 W/m^2 = 357 petawatt

    Temp of earth that emits this power:

    ~280 Kelvin

    delta-T caused: 0.0003 C.
    delta-T if considering total human energy usage: 418 * 10^15 Btu / year = 14 terawatt => 0.003 K
    since if P = {const}T^4: dT = TdP/(4P)

    So whatever the temperature of the earth is, only about .003 degrees of it can be accounted for by the industrial output of mankind. The effect on the temperature of the earth soley as a result of human energy usage is significantly smaller than as a result of solar variance. If man is to have an effect on the earth's temperature it must be by affecting the heat transport rates.

    side note: It's cheap, easy and fun to recharge the refrigerant in your car's AC.

  14. Insurance is a ripoff. on Using Google Maps to Get Out of a Traffic Ticket · · Score: 1

    In aggregate, it must be a ripoff: the insurance companies that do not profit cannot survive. So knowing that your risk/reward ratio is less than one, why would you buy insurance at all instead of just socking the money away just-in-case?

    Well the reason seems to be: you could get in an accident and need the money at any time, including after the first couple of payments, but you're only going to have saved enough close to the end of the socking-away period.

    Well once your personal liquid assets sufficiently exceed the minimum insurance level, shouldn't you be able to use those as collateral against actually buying insurance purposes?

    same thing for health insurance: you shouldn't be using insurance to pay for expected recurring expenses, like visits to the doctor. If you need a yearly physical, and you pay yearly insurance for it, you're just playing a shell game which by design cannot benefit you.

  15. Re:Hopefully the guy was innocent. on Using Google Maps to Get Out of a Traffic Ticket · · Score: 2, Interesting

    I was on a highway once, had just turned on and needed to be in the left lane for a left-hand turn fairly quickly, so I accelerated up to highway speed the and made my way left, one lane at a time and checking each time to make sure. The last two lanes contained: 1 van moving a little slower than me and slighly behind and the far lane: 1 motorcycle, quite far back but rapidly closing. I must've underestimated the bike because it was closer than I expected when i checked for the final lane change. My turn was approaching rapidly though and I didn't want to slam the brake in front of the van (I would've had to slam hard to execute the change "safely") the other choice was to accelerate a bit, pass in front of the bike and slow down in the turning lane leading up to a light. This plan seemed required the least amount of accelerating so I chose it. While in the lane before the turning lane, the bike closed to my bumper.

    Well it turns out it was a bike cop. There is a light, so I'm stopped in the turn lane when he pulls up *between* me and the car to my right and says, "Do you know what the speed limit is here?"
    "50" (i'd been going 50, so it seemed a safe bet.. turned out to be 45)
    "Well it sure as heck isn't 65"
    I don't know where he got the 65 number from. HE was going much faster than that and it took half my nerve to keep from saying, "Well you shouldn't have been going that fast then" but I know if i had, my seatbelt would have mysteriously been unbuckled and i'd probably turn out to have a broken tail light.

    So the light turns green. (my light. the turning light. of a 10 lane highway +2 turning lanes) the cop then drives between the lines of traffic and drives straight across the intersection.

    And to augment your statement about not speeding, they get you both ways on that one. Many states have a "reasonable and prudent" clause in their speeding laws. It means two things:
    1) if conditions are poor, you should be driving at a reduced speed. regardless of what the number on the sign is. They can ticket you for this.
    2) (and this is the tenuous one) you can get out of a speeding ticket if you truely are 'going with the flow of traffic', but I don't think that's ever worked and it's got another edge to it: they can ticket you for driving too slow if the 'flow of traffic' is speeding.

    So really, you simply can't win. Pay the nice man his protection money.

    I think what he's asking is, what if game developers decided on a "standard system" and coded one path directly to that, while using the abstraction layer for everything else. If you had the standard system, you could run the game in "console" mode and take advantage of all those optimizations.

    The different software houses could update the specs every 18 months or so, but use the 'reference systems' to allow their software to either 1) run on older hardware or 2) run much much better on current hardware. There could be a couple of competing standards, but the reference systems would have to be announced when the reference hardware is state-of-the-art even though they'd probably actually be used when the reference hardware was "doesn't-quite-need-an-upgrade-yet" so people could buy state of the art systems, but still get some use out of the machine as it aged.

The current is the same through each of the dogs and the resistance (or at least the relative resistance) is known. The voltage can then be calculated from ohm's law: Vgen = IRgen and Vbpark = IRbpark.

    then insert the following after the next paragraph:
