Halleluah! Merry Christmas! Thank you for the precedent

That's a misinterpretation. The next step to 0K from 0.0001K is not 0K, it's 0.00001K. And then 0.000001K. Til eventually 0.(infinite zeros)K. You won't ever get there unless you empy the space you're working on, meaning you can't act absolute zero upon an object (which you couldn't anyway without destroying its mass which is impossible). Exactly. No temperature = 0K. Did you change your picture? Hey, going back to the blonde guy, does anyone know how they're getting the great depths of the universe at 0K? Surely it's a calculation thing, but I'm wondering what they base it on.

It can, but this opinion will be a heavy influence on future cases, and I heard somewhere that the Supreme Court will probably avoid these cases, so this is a very good thing. There will no doubt be appeals, but I'm not concerned. Rejoice! -

Hey are we sending this person/people (more specifically Dover, Pennsylvania) an award or something? If so, what? I'm about as fringe homeless as it gets, but I'll chip in.

Oh, I'm going to Hell, but I'll also be the last off of the island (to use a reality show metafor to speak their language). Viva la vida!

If nothing doesn't have a temperature, wouldn't it be 0K? If it were nothing it wouldn't have a temperature. There's nothing there, no motion, nada. 0K? I mean beyond the reach of the electromagnetic spectrum, not in the depths. I mean beyond the depths. I mean nowhere. I mean outside of our universe but still part of nature. What are you talking about? Seriously. I don't mean that as a huffy puffy or anything, I mean seriously, what are you talking about? Is this a theoretical thing? I'm a huge fan of physics but still in Newton stuff.

I'm curious about this myself. My dreams are very very long and very very detailed and I think that it has a negative effect on my memory. Does anyone know of any good and valid dream research? Thank you for that link m4rc

I know, he ripped me off, but I don't mind. I'm fearful of the day I'm having surgery and there are complications and the I hear the lead surgeon say, "Let us pray."

They aren't scientists and engineers either, however their stand may be very important for future generations of scientists and engineers, and teaches a very valuable lesson for politicians being lobbied to do something that isn't the best for the community they represent, even when the demographics make it look like it. Dover was invaded, and Dover kicked the invaders out for the good of the future of their children. That's why I nominate Dover, Pennsylvania as SFN's 2005 Person of the Year for making a stand for the future of scientific education in America. Because:

True absence in nature can only be determined by finding a place that is 0K, which is void of all mass and is even outside of the farthest reaches of the electromagnetic spectrum. Making the measurment of this area itself violates this nothingness to an extent for it will never naturally return again because of the infinite orders of magnitude this space must go through to return to 0K. However, 0K does exist in nature, by definition, where truly nothing is. With that said, the temperature of 0K can not be applied to an object simply because it contains mass that is made of energy. Matter can not be created or destroyed so the object can not be made 0K simply because you can not destroy mass. Surely there is a threshhold in between, and is likely unique to each element, and it's one I find most interesting. Possibly, you could make the space the object is in 0K, but you've have to evacuate everything out of it and I mean everything and stay far away from it.

What I'm saying is that's a tough one and you should probably look at other stuff. But, and I'm only guessing here by IUPAC rules, the name is, 4-hydroxy 1,5-oxy 1,4-hexadiEn-3-one I'm sure this isn't right. This one is really tricky for me. What screws me up is the oxygen para to the carbonyl. It's not benzene and I can't call it cyclohexadiene because that leaves out that oxygen. Definitely not toluene, that's all I can be sure of.
-
I'd give it to Dover, Pennsylvania for defending themselves against lunacy. They voted for their children to be taught the truth, even when the ratio of churches to people in that town is ridiculous.
-
This isn't toluene because it is not a substituted benzene. The functional group naming hierarchy goes: Carboxylic Acid>Anhydride>Ester>Alkanoyl Halide>Amide>Nitrile>Aldehyde>Ketone>Ether>Alcohol>Thiol>Amine So it appears to me that you have... ... I was going to name that for you but I got snagged. I'd keep it a little simpler if I were you since you haven't taken one yet.
-
I didn't either, he rarely says anything, and I try to see it all. I'll look around for it on TV and the net and post whatever I find.

Absolute zero is the temperature of truly empty space, and is not possible anywhere else.

Did anyone happen to see the story on ABC news? I don't remember them using the word evolution, but maybe they're targeting an audience with information before they tune it out for the greater good. We're all african, and skin color is all about feedback in vitamin D production. Biology is very much not my area at this point but I have a few questions. I've always envisioned mutation that drive evolution as absolutely "random" (without having a cause and effect relationship with what is needed) and can not be dictated by environment (only selected against). But when you looks at pigmentation about human populations that have spent a decent amount of time where they are all pigmentation seems to change like a slide ruler. Like Africa, black skin dark hair. Turkey, brown hair brown skin. Germany, white skin brown hair. Ireland, white skin red hair. Scandanavia, white skin blonde hair. Even hair color appears to get lighter as you travel north of the equator, and I have no idea how hair color would give you an advantage other than sexual selection. Like, maybe my german heritage is the reason why I have such a thing for brunettes (though I do like them all, my favorites though are always brunettes), and maybe the same thing has happened in these other cultures because of their own pigmentation. Is the deal with this mutation that the gene became a slide ruler (adjusting across generations to the direction pushed to make the right measurement)? If so, is it dominated by feedback? Are there other genes like this? There's also this: From: http://www.primates.com/chimps/chimpanzee-info.html Could this be the same thing or a very different thing entirely? I guess a more direct question would be, can a person with this mutation have black skin? Are we sure of a split with this gene? I'm just looking for some clarity. I'm seriously handcuffed when it comes to genetics.

Thanks ecoli, now I am officially a biologist. I'd better update my resume. Is this what you study ecoli?

The nitrogen was in excess. It was about 1 liter of N2 versus 250mL H20, which was probably about 18ºC out of the fountain (it runs a little cold). All the rooms of that building are kept at 22ºC, when the heater works. That clump of ice was hard. If I was wearing some thick gloves, I'm sure I could have beaten someone to death with it. It was hard as a rock.

The didn't seem cold. Just well swept. As the liquid nitrogen spread out, you cold see all of this dirt piling up at the front of it. And these floors were clean.
-
When we did it we poured about a liter of liquid nitrogen in a styrofoam cooler and then got a cup of water from the water fountain. We poured it in all at once and the cooler just shook violently because the heat from the water caused a lot more of the nitrogen to boil off rapidly. After it settled down a little bit we fished out the ice and it was pure white because it froze so fast it had a lot of air in it. And it was frozen hard. Very very hard. We left it out after we got rid of the liquid nitrogen we left the ice out and I don't remember any of it melting. The ice was very very cold. Another cool thing to do with liquid nitrogen is cool if you have a linoluem or tiled floor (not carpet). After we were done Dr. Ho went out into the hallway and spreadout the nitrogen on the floor with one big pour. You'd be amazed out how well this sweeps the floor. But if you've ever seen a little drop of water dancing around on the surface of the hotplate, imagine that but everywhere as the nitrogen danced all around us while it boiled off.

I'm sorry to bother the forum with this but a question came to my mind in a part of physics I have not studied thoroughly and the semester is over so I can't bother any physics professors right now and I've come to an assumption and I was curious if it was valid. Say you have a solid body in space that is hot, it's excited molecularly. And it cools. Did the heat escape by emission of electromagnetic waves?

I can scan very very quickly. But when I read I read very very slowly. I once took a test that concluded I read at a second grade level, which is ridiculous because I make sure I comprehend everything. A lot of times what I'm reading will make me daydream or research something or work on something a little bit. I normally only read somewhat dense material. Today I read a section of my Linear Algebra book and a chapter in my Biology book, I'm about to read some Physics or maybe some Analytical Chemistry. Later I'll relax and read some Principia Mathematica. You may say I'm just studying, but I'm on break. Whenever I read something I normally end up thinking a lot about it no matter how hard I try and I try to make sure I really understand it. I only read non fiction because fiction is baby babble.

Congratulations for the end of another semester...

It seemed like we got out a bit early. But we go back early too, January 16th.
