Why is absolute zero finite compared to maximum heat (which is seemingly infinite)?
wrote in message ... In sci.astro wrote: This is not philosp[hy but physics, so what it "seems" to you is irrelevant. Temperature has a physical definition and it is *not* energy. So let's do some physics! Are you saying that Temperature has NO relation to energy of a system? That's clearly not true! However, Zero temperature is clearly NOT zero energy (which I believe you are also saying). It would be for non Quantum, non Relativistic physics. In the thermodynamic (ideal gas) or Kelvin scale, i.e. non quantum, non relativistic, quite apart from non condensing (!) Zero temperature is defined as when isothermal and adiabatic processes are identical. In other words when a system undergoes an isothermal process with no transfer of heat, the temperature at which this occurs is called absolute zero. It's one interpretation. Probably more mathematical than physical under the circumstances. Obviously by that definition a zero point energy CAN exist. But hey, what if I now REMOVE in some manner a quantity of that zero point energy. Is the system now at a temperature BELOW absolute zero? What exactly do you mean by 'remove some 0-point energy in some manner'? Have we extended temperature into a negative region? Could the Kelvin temperature scale consist of more that simply positive numbers? Now this is getting into philosophy since I don't think anyone has removed any zero point energy even in theory, but it is interesting. Or not However, if you wish to stick with just physics, then lets just say that by removing some zero point energy, I thought we were sticking with physics. How would you remove this energy without risking adding some energy? we have gone outside the range of the definition of Temperature, thus, the system no longer can be said to have a temperature at all! Is that not true? Well. let's just get past the "if I can" stage first OG |

The incidence of humor impairment appears to be rising Yes, I've been observing this too. and I've been worried that it was me who had acquired it. A number of my lines have fallen flat lately. Well, when dealing with the humor impaired, any line will fall flat. Over the last six months, I have been slllooowwwly working on replacing the horsehair plaster in two closets with blue board. The goal was to 1. Eliminate two chimney effects (the holes were in the ceiling which goes to the attic which goes to the outside) and 2. Eliminate doorways for 4- 6- and 8-legged critters. Good luck with this:-) They always find more doorways. I have a compendium of stories about this effort but I'll tell the latest one. Closet #2's ceiling had 55% of it already covered with some kind of wallboard. The other 45% had exposed slats, dripping horsehair plaster, insulation and gaps where 4-legged critters had bulldozed a pathway into the closet. They used this lane to fill the pockets of my suede jacket with seeds but that's another story. Closet #1 had to be completely stripped of plaster (ugh!) and relined so I had some blue board left over for closet #2. The dimensions of the replacement space in Closet #2 were about 7-3/8" x 6'. I didn't have any strips of board left that were 6'. However I did have one strip of board that was exactly the width I needed but ~38". The other strip had be cut down to the 7+" width but was also short. So after I had cut the width, trying out each board to make sure they would fit widthwise, I started to work on examining the length part of the project. I took Board#1, put it up and marked where it stopped, placed Board#1 on the floor. I took Board#2, put it in place and noticed that I was short an inch. Oh, well...I can't expect exact fits with no cutting all the time. So I laid both boards down to dry out, get warm. The next day I screwed in the first one. I got the second one up and it didn't fit; it was too long by 1/2". The damned board had grown longer. Since I was already pooped, I quit for the day instead of trimming the length of Board#2. I have been reading physics newsgroups for a long time. The next morning, I decided that, if the ****ing boards could grow longer overnight, perhaps they can grow shorter overnight. Hey, worth a try. Sure enough, they had. The second board was exactly the correct length and it fit in tight. So I screwed it in before it changed its mind about which length it wanted to be. Yes, you have to nake the best of the periods when they're in a cooperative mood. Now, all I have to do is figure out how I caused it, figure out how to can it, then all I have to do is sell it to certain accelerator sites. Sure, go for it. You probably got some combination of thermal expansion and swelling due to changing humidity. Mostly the second, I would guess.

Yes, you have to nake the best of the periods when they're in a cooperative mood. I guess the art of carpentry is to know when the pesky material is cooperative. And to what extent it is willing to be cooperative. Yes. I have 10 more years of practice before I learn. That's about as much as the average apprentice used to spend (while dealing with this stuff all the time, not part time). The belief that "since this is not traditional university material, it must be simple" is totally off.

That would make a big mess if it did that for all blue board. I've been having strange measuring problems which is why I've been resorting to physical fit rather than transformations. I'd really, really like to figure out what I'm doing that causes these errors. Can't tell you without seeing how you're measuring. When I first started closing critter doorways, I was using the official carpenter's tape measure. I always ****ed it up. Since I failed trying to figure how I messed up, I started using my dressmaker's tape measure. That seemed to help but I have no idea why it helped.

That's about as much as the average apprentice used to spend (while dealing with this stuff all the time, not part time). The belief that "since this is not traditional university material, it must be simple" is totally off. Yep. Those machinists in any production line in factories are amazing people. And it's almost poetry to watch a guy mix and apply _lumpless_ plaster. I've never watched a whittler(sp?) of wood but I bet that's instructive as well. Now, all I have to do is figure out how I caused it, figure out how to can it, then all I have to do is sell it to certain accelerator sites. Sure, go for it. You probably got some combination of thermal expansion and swelling due to changing humidity. Mostly the second, I would guess. I thought of that but 1/2" or so? Yes, that's a lot. Ha. AND the width didn't shrink so it can't be a physical phenomena. It's got to be me ****ing up unless I've truly become a magician and can change physics laws. In this case, everybody had better watch out when I'm on the road. That would make a big mess if it did that for all blue board. I've been having strange measuring problems which is why I've been resorting to physical fit rather than transformations. I'd really, really like to figure out what I'm doing that causes these errors. Can't tell you without seeing how you're measuring. Yep. I've been trying to "observe" myself but that doesn't work anymore; I used to be very, very good at that. I've demonstrated that my brain is not functional anymore by doing the inequality sections in my calc 101 book. ~70% of them ended up bassackwards. Now all I have to do is figure out how to get a red flag to wave whenever the flips flop. When I first started closing critter doorways, I was using the official carpenter's tape measure. I always ****ed it up. Since I failed trying to figure how I messed up, I started using my dressmaker's tape measure. That seemed to help but I have no idea why it helped. What was really screwy is that it took the posting of my story 24 hours to propogate. Time dilations? Perhaps:-) Well, we'll test this one again. I have a couple of hypotheses that I'll get around to isolating if the behaviour continues. For the last two nights, the critters in the attic (which I am now aware exist) started to create more chimneys. So all projects are now on hol[e]d until I kill the sunovabitches. Every improvement has three adverse side effects. I can't wait to find out what the other two are. /BAH Subtract a hundred and four for e-mail. |
