Reamur, Kelvin... what's the difference :)

  Negative 40 Kelvin has no meaning ;)

    That's what you think. Who says there can't be a -1 degree Kelvin? Just because it doesn't make any sense sense to us whatsoever right now doesn't mean it couldn't exist. Do I know how to reach -1 degree Kelvin? No. But 1920's physicists didn't know how to destroy entire cities in Japan with a hunk of metal, either.

    It has some meaning. It's hotter than any positive temperature: http://en.wikipedia.org/wiki/Negative_temperature http://en.wikipedia.org/wiki/Negative_temperature :-D

    Actually, there are systems that have negative (absolute) temperature, and "a system with a truly negative Kelvin temperature is hotter than any system with a positive temperature". http://en.wikipedia.org/wiki/Negative_temperature http://en.wikipedia.org/wiki/Negative_temperature These are strange systems that can absorb only a finite amount of energy. When they are almost "full" of energy, their temperature is negative. (For simple systems the negative temperature appears when they have more than the 50% of the maximal energy, but it depends on the system.) This can not happen in normal systems. For example an ideal gas can absorb infinite energy, because the molecules can go faster and faster.

    No, but +574 is the same in Kelvin or Fahrenheit :)
