    But missions to Uranus and Neptune did happen... regardless of when they did happen.

    Sorry, but the when was very important. The circumstances that allowed Voyager 2 to travel to Uranus and Neptune only happen once every 176 years.

    The mission extension to the two outer planets only took place because of a lucky coincidence.

    - We since launched robotic missions to every planet (including Pluto) in the Solar System



    We haven't sent any missions to Uranus and Neptune since the 70s. It's just that the probes that were launched in the 70s took until the 80s to actually get there. And none of them were there for a long-term science mission á la Galileo or Cassini.

    What an absurd idea. That wouldn't get anyone elected. Besides, law enforcment is expensive and would be a drain on the governments finances. Making a couple of laws is so much cheaper and demonstrates activity to the voters.

    First of all, breathalyzers are only accurate to within .02. So that .08 reading could be .1, but could also just as easily be .06.

    That would be one interesting bit of information to glean from the breathalyzer firmware - does it account for measurement errors and give a "minimum" value, as in "this guy has _at least_ x% BAC" ? Or does it merely output what the raw measurement says ?

    Over here, at least speed traps work this way. If you get caught, they always send you the measured speed, but you get fined as if you had driven (measured speed - maximum error). Of course, the maximum error is rather low (3 km/h), so if you're doing 30 km/h over the limit you're screwed anyways.

    What happens if you belong to a religion (such as the Jehovah's Witnesses) which regards blood as sacred, and refuse to allow the blood test on this ground?

    I would assume exactly the same thing that happens when you get convicted and sent to prison, but you refuse because your religion does not allow it.

    At some point, these measures become mandatory and your consent is no longer required.

    20 percent? I wouldn't call that "unfortunate" -- I'd call that broken. Not really. If the calculation itself has an error of +/- 20%, and the device reports the -20% value, then the DUI suspect should call himself "lucky".

    It's just like the guy who wanted to challenge a radar gun speed measurement. The dialogue went something like this:

    Guy: Is the reading of the device always accurate ?
    A: No. It gives wrong values if the measurement is taken at an angle.
    Guy: In what way will these measurements be wrong ?
    A: They will always be too low.

    Someone will realize something bad is happening with a laser when the first person gets shot with it, possibly in the eye, and starts screaming.



    Retinas do not have pain receptors. People who are not familiar with the symptoms will not realize what exactly has happened (and that their vision is going to be irreparably damaged) for quite a while.



    It's an interesting double standard. Think about it.



    The laser toy would allow you to leave several people crippled for life _and_ get away before anyone realizes what has happened.

    You will likely close your eyes or look away way before any real permanent damage is done.

    Good luck closing your eye in less than 10 milliseconds.

    It's pretty obvious that a laser that can light a match is seriously dangerous if miss-used.

    No, it's not. If you don't know about the properties of laser light (monochromatic, coherent, low divergence) and what happens when laser light passes through a lens, you will seriously underestimate how dangerous this stuff is. This is a few steps above using the sun and a magnifying glass.

    Yes, it really is brighter than the sun.



    Not just that - laser light is also monochromatic, coherent and has a very low divergence (things that don't apply to sunlight). This means that it will be focused into an extremely small spot by a lens (such as the one in your eye, which will ideally focus it into an extremely small spot directly on your fscking retina).
