    Who exactly is "us"? A group of young students who want to be scientists one day?

    What's so confusing about it? Stick it in whatever you're measuring and wait a bit - then read how high the alcohol/mercury went. If it's an infrared thermometer, point and click. If it's a thermocouple, read the big numbers on the display (assuming you don't have to calibrate it).

    if it's an anal thermometer I'd say it's very important to get it right the first time

    When it's very important to know what temperature something is at.

    when is important to know the temperature anywhere inside ur house, outside in the cold, the warm, when is it important

    when is it very important to know anything?!?

    (refer to brewnog)

    ya know... "the importance of knowing" is always subjective and therefore relative.

    my 2 cents:
    perhaps it is more important to know who asks the question? ....

    For example, water freezes at 0 degrees C (32 degrees F). When you are landing an airplane on a cold wet runway, if the runway is at -1 degrees C, you could crash because of ice; but if it is at +1 degrees C, you are OK.

    Wrong. There is a big difference between landing on an icy runway and landing on a wet runway, for example. People with responsibilities (like pilots, and airport managers) can't afford to use cop-outs like that.

    When we have no sense of temperature ourselves?!

    of course, you are right Aether.

    strawberry and banana smoothies are made with ice.

    Did you forget to pull the carb heat lever? On any decent size of runway, there's no need for brakes, so ice isn't that big of a deal. You don't get weird **** like pressure ridges on a reasonably well maintained strip.

    Mobb, the primary times that temperature is critical are in physiology and delicate experiments about chemistry, physics, etc.. For instance, you have to monitor body temperature very carefully during surgery.

    i was just asking a question for my project, this is supposedly to be a science forums not a playing forums :frown:

    One of these days you may have a kid/s and s/he may seem sick and you might want to take their temperature to find out if s/he is sick. Or you might be sick yourself one day, and usually it is a good idea to take your temperature.

    Hey Aether;
    I must confess that I was thinking of the kind of things that I drove rather than those flying hotels, but I would still contend that the runway ice itself wouldn't have caused an accident like that without the accompanying storm conditions. I might be wrong, but I've never heard of it happening in calm weather.

    Hello Danger, perhaps it is more an issue of being able to steer than anything else. An airliner can use up quite a bit of runway in order to come to a complete stop.

    There is that. I tend not to think on that scale, being, as my signature implies, a guy who once parked a Cessna in someone's back yard. :biggrin:

    I figured that mobb would naturally picture an airliner when I said "airplane"...back yard, eh? Did you break anything important?

    Naw. I was practicing short-field TO's & landings, and there it was. (It was actually a pretty big yard, but I like to omit that part. :biggrin: ) It belonged to someone I knew, and I had permission to do it.
