Muf, I've been away but it looks like Monbiot is slowly moving from the dark side.

Humph! At least my political input was based on current policy. High five SoM!

 

Now, if you’ll stay with your thread a bit longer, I would like some advice (if you’ll give it).

I’m in discussion with a professor of thermodynamics that teaches quantum theory as well. OK, but he heralds from Central Europe (Germany, I think) and much of what he says is difficult to understand. It was ages before I realised that "F.ex" wasn’t a "function", it was a "for example" abbreviation!

We are currently discussing LTE (local thermodynamic equilibrium) and BEC (Bose-Einstein Condensate) in that order of quotes.

Yes there is .</cite>

<cite>And this is why the LASER is fine tuned to the temperature of the mass and a suitable trap for the cold mass is employed.</cite>

<cite>

No the laser is not "fine tuned" to any temperature . It must only emit a frequency that is absorbed with high probability by a given atom . That depends on the quantum energy spectrum which is independent of temperature (there is no T in the Schroedinger equation , one only needs to solve for eigenvalues that respect H.Psi = E.Psi) .</cite>

In my first statement on LTE I just said what I thought he’d already told me. Seems I’m wrong.

In my second statement on BEC I just said what I thought was relative to the energy levels of the molecules that could result in cooling.

Can you explain how I misread this? I’ll admit that I’m at a loss. As an engineer I only manipulate science for the benefit of mankind, but this is getting harder when the science tends to contradict itself.

Best regards, suricat.

It’s at ClimateAudit.org muf. "jae" is a poster in the forum there (and seems to be a competent chemist) that shares my scepticism of the ‘back-radiation’ in the ‘K&T’ schematic. The post title is "STILL WAITING" and has, so far, run to 24 pages. The ‘professor’ in the thread is "TomVonk".

I’ll give you due warning muf! Since the "Briffa" scenario, the site is running really SLOW! You will probably need to hit the "refresh" button more than once to get in and it seems that it’s occasionally operating in ‘safe mode’. It seems that Steve_M has a lot of "cud" to chew.

Best regards, suricat.

Hi suricat, good to hear from you. Apologies for the following anologies. I think how to visualise this is to forget about compounds and different atoms and think about the set of discrete quantum energy states possible in the ensemble. Then analogise to a collection of catchers (atoms and molecules) with different sized hands fitted to catch and throw different specific sized balls(photons of a fixed set of frequencies). A catcher can only hold one ball and it must be a specific set of sizes at a time but can hold no ball as well. So you'll have either saturation when all catchers hold a ball  so a sort of saturation equilibrium ie as soon as they throw one they catch another because there are plenty to catch.

You'll also have a dynamic equilibrium where balls are being caught and thrown at the same rate but there is capacity to catch more balls if they are supplied and because you're dealing with large numbers there is a steady average energy equilibrium.

When it comes to BEC as I understand it this is a special state where the ensemble is Bosons (spin -1 particles) in their lowest quantum energy level and if you're dealing with bosons then there is a big restriction on the photon energies that can interact (the eigenvalues) for the particular Boson but the Pauli exclusion principle doesn't apply so similar states can coexist and I think this means multiple balls can be caught, held and thrown, refering back to the anology.

I couldn't find the dialogue on climateaudit to which you allude. As you'll see my knowledge and understanding is only cursory and possibly inadequate for your needs.

Well I suppose we all could do with a good laugh. Here's a link to the start of the thread: http://www.climateaudit.org/ph...8488234ee25c&start=0 The site seems to be responding better recently, but don't rely on this. If your browser doesn't load, hit the "refresh" button. BTW. We seem to have server problems on the reply box again. Paste the URL destination into your browser!!! Best regards, suricat.

Son of Mulder: For the time being, Climate Audit forums are on ice pending the physical site change of Climate Audit! This is worse than the C4 shutdown as there wasn't any prior notification of the shutdown. You'd think Steve_M would be a bit more sensitive on this following his data loss post the C4 shutdown. It seems unlikely that the forum facility will be continued in its prior format (thanks to Watts' lack of interest in its continuation). OH NO! An incomplete dialogue box again! Let's see what the post is like. Best regards, suricat.

It still isn't right, is it! You'll need to paste the link into your browser to get there!


(just realised, I need to hit return twice to get a new line here). There's something fundamentally wrong with the protocol here. When I paste back from the site "Word Pro" shows a two line spacing that wasn't evident in the 'dialogue box'. Some really odd things are happening here!



Best regards, suricat.
