from the news page:

Nothing so perfect as a Friday, despite the fact that it is 0 degree's out right now. I always think of zero degrees as a universally perfect constant, because in my mind, it means there is no actual temp. Then I walk outside and realize, as my nose freezes shut and my 'boys' retreat into my body that I am in fact an idiot.

Which is likely the real universal constant.

see, actually if it were -275.15 degrees celcius, or 0 Kelvin, then there would be no temp because that is absolute zero, and nothing can move at that temperature. unfortunately, we cant really get anything that cold to ever find out.

on another note, weather forcast for escondido, CA is 65 F all week, which is 18C, and its sunny! sucks for people who have winter.

I know. I have to work outside tomorrow, but it's ok because I am also in San Diego county. Lovein' that weekend forcast. :heh:

I think space is about 4 Kelvin. If you go out into space without clothing, you'd get a pretty good idea of how it would feel. You'd probably die though...

true....scientists have been able to get things to something like a tenth of a degree kelvin, but never to absolute zero.

You know, this might come as a shock to some of you... but some people actually like the cold!!!! :P

close, but it's actually -273.15, not -275.15. i had to say it, i'm a chem major....

one of my profs was talking a while back about how there actually isn't "absolute zero." she was sayin' that even at "absolute zero" there still remains some energey to have atomic or electronic motion. i think it was in quantum mechanics class in the harmonic oscilator model. since the energy levels are quantized and the lowest level is not at the bottom of the well, there's actually energy at "absolute zero."

whatever, i'm sure no one else really cares but me. my point is that it's -273.15, not -275.15. nuf said.

That is because science deals with theory, not the real world. Just as there can never be a true line, there can never be a true vacuum and there can never be a complete absence of energy.

I beg to differ. After a large meal, or mowing the lawn in 95+ weather, I achieve a complete absence of energy.
