Well the rate of propagation of a scent is actually pretty impressive I think, compared to the rate of conduction of heat. Interesting. Nice contribution. I agree that the informational problem is not coherent, but this only adds to the criticism of the interpretation of heat as vibrating atoms. You are the first that I have seen to accept this criticism. I hope I am not stuffing words in your mouth. You use the word 'organized' yet would we call white noise organized? Here there has to be a stronger characterization I think. Even if we put 100 small white noise sources up to a bar of steel we may still possibly measure the 101st's rate of propagation so long as it comes alone after the others are established, and we have a sufficient power measuring device. Then too, we'll be heating the bar with our sound devices won't we... I think this recognition that heat is actually open to reinterpretation should be placed alongside the mysteries of mass that we see in present day. If anything this should be good news to the string theorist types, but instead they fit their theory in beneath existing physics. From the informational perspective we can use heat to signal, and its low pass effect can be helpful for some signal processing. As a delay line this is kind of sweet. So for instance a piece of steel wire and a piece of copper wire terminated with thermocouples would show unique signals even when applied to the same variable heat source. Varying their length should alter the filtering mechanism. In terms of duty cycle measurements or power measure these should be fine. Some of the best electrical RMS measuring devices use heat measurement don't they? Unlike other signalling mechanisms the maximum usable frequency of a heat conducted signal varies inversely with distance. - Tim

I accept any rational critism but your critism of physics seems unfounded since you seem to be ignorant of it. Scent is distributed by Brownian Motion.

Scent is distributed by > Brownian Motion. Yes, you are leaning on the gas form to make your way. And it takes just a tiny bit of scent vapor in the air to be detected. I suppose we could go on to challenge adiabatic type behaviors, but I'd just as soon stick to the solid form. The gas form is much more challenging. Place a gas in outer space and baboom! it distributes itself out. Place a solid in outer space and it just sits there, solid as ever. Will you extend your claim of Brownian motion onto the solid? I'm not so sure that diffusion and brownian motion are exactly the same as you are claiming. Here is a statement: 'Brownian motion is observed in molecules that are so large that they are not driven by their own thermal energy but by collisions with solvent particles.' - http://en.wikipedia.org/wiki/Diffusion I'll admit the difference is subtle and they are closely related. Diffusion does not require any temperature difference as I've attempted to discuss. Your bottle of scent can be the same temperature as the air it is in. Still, I do think that the example is a nice addition to the conversation. Yes, when you open it it may cool a bit as the scent evaporates. This is very complicated stuff and I believe that the solid example is a more simplified environment to puzzle over. - Tim
