I'll kick it off with second sound.

In any material, thermal energy is stored as atomic/molecular vibrations. Since the atoms don't vibrate independently and bump into each other, you can consider these as waves traveling through the material. You basically have sound waves crisscrossing due to thermal energy.

Due to wave/particle duality, you can also consider these sound waves as consisting of sound particles. You now have a gas of sound particles in your material. The higher the temperature, the denser that sound gas.

Now for the mind blowing part. This is a quantum mechanical quasiparticle, but it basically behaves as a classical gas. That means it can support density waves. Density waves in a gas? Classical sound.

You now have sound waves in a gas of sound particles. This is a real mode of heat transport in certain materials, and we can even measure the speed of this second sound.

I guess it's not mind blowing here, but it always amazes me how few people actually understand the laws of thermodynamics. When you tell them energy is always conserved they're always so shocked at how it works, yet it's an extremely basic principle energy in = energy out. I think it's more of a mind blowing fact for me that people don't know this.

I do not know how much of it is bullshit, but if we assume entropy is directly correlated to the amount of information in system and assume bell theorem is right, we can consider all these unpredictable events as the source of new information and entropy in the universe.

Random doesn't mean what you think it means. These thermal vibrations follow highly predictable statistics. And the second sound waves are waves of density in the phonon gas.

>What's the most mind blowing thing you know?

Well my mind doesnt stay blown for long really.

But i can tell you the most interesting discoveries ive made in my life recently.

As of recently in my life ive changed focus from debating as a life's pursuit, utilising scientific method, towards certain areas of research to continue my commitment to progress and the personal attainment of the singularity. I have become interested in the science of attention. It seems reasonable to me that all the models we use, from debating procedure, critical thinking, right down to scientific method etc. They are all just similar ways to focus the attention of the human brain into a fashioned capable of permeating the mysteries.

I am not too sophisticated with maths having been born dyslexic. However i do have a strong ability to ask the right questions and attain answers which are repeatably provable. It has occurred to me that the way in which humans divide attention often involves breaking a problem down into phases, weather its the phases of scientific method or some other method these serve to divide attention into units. I think that we do this because things which have KNOWN phases can be more quickly summed as you progress through the phases one by one. This can be repeated, and provided its a successful pursuit it will be kept by natural selection.
Whereas characteristically things of UNKNOWN phases tend to be generalised and viewed as a large unbroken unit. An insoluble mystery. As Sherlock would have put it. One of the most successful ways which we have broken down phases is with counting. We even tell ourselves that the measurements we use for counting are accurate, though obviously not totally accurate, as that would require a unified theory of physics.

Continued part 2.

>> No.9734836

>>9734787
Continued part 2.

So, armed with this observation i also began to look at how we as humans apportion attention. It is a stereotype that intelligent people spend all their time planning for the future, wheras other people have equanimity and "live in the moment". It is also said that if you do not learn from history you are doomed to repeat it. Buddhists in particular with their attention on "mindfulness" seem to cultivate staying in the moment to fully experience it, and they gain many scientifically measurable advantages. Such as an increased IQ score just after meditation, and the ability to resist intense pain. The way in which they cultivate this ability is by practicing holding attention on the moment, especially in uncomfortable moments. Thus i am personally trying to cultivate the ability to 'switch hit' from all three phases, past, present and future.
Due to this i also have watched a Youtube by Daniel Goleman, who better describes his research on the matter. But one of the most mind blowing things which he said was that peak attention was not a negative correlation to stress. Rather that attention peaked somewhere in the middle of stress, when someone attained what is sometimes called flow. So from this i think we can take that a little stress is good for attention.

https://www.youtube.com/watch?v=HTfYv3IEOqM

If you think im an idiot, please tell me. If you think this is all completely obvious and can already be practiced with 100% success, then please stop wasting your time reading this. This is for people in a transitional stage of focus. For people that, by necessity only ever study what their job or university paper deems worthy, rather than the methods by which they achieve it.

to clarify, what I meant was, isn't that just describing the same natural phenomenon using a different model?
yes, obviously if you take into account that heat is atomic vibrations you can describe the diffusion of heat as a wave propagation.
or you if you describe heat as an energy field, you can analytically describe heat diffusion that way.
I'm not sure if I'm explaining myself well enough.

>> No.9736769

>>9736766
Oh, I know what you mean, and I understand your confusion, but it genuinely is a different thing altogether. Heat distribution by diffusion can be modeled as phonon (and electron) transport, and that is indeed not very special. Just a recasting of the same classical phenomenon.

But second sound is actual a density wave in the phonon gas by which heat is transported, without transporting the heat particles. It is not diffusion, and it is an effect which can only be properly understood by understanding phonons as quasiparticles.

Reminds me of the thing I tell people who are struggling with something in their life, I tell them they need to tell someone about it. The act of breaking down a problem into communicable chunks for another person to understand helps the person understand it better themselves. Instead of a shapeless blob of 'everything's bad' the issue becomes a structure that can be mentally disassembled and examined, and a person can more easily see where changes might be made to improve things. I guess it's more /adv/ than /sci/, but it has the same logic I think.

nevermind it appears the answer is yes... then is it a significant heat transport mechanism in nature as compared with regular diffusion

>> No.9736799

>>9736789
Not really as far as I know. It's mostly a fancy effect that you can create in a lab under very controlled conditions. Heat diffusion by typical phonon/electron transport is the main contributor to heat transport in everyday materials.

I'll have to take your word on it. I get where you are going and what you explain is intriguing (so I will read up on it), but I still don't see in how far there is a difference.

To me, if I want to solve a temperature field problem, I take into account the heat flow rate.
That would be the equivalent of your "heat particle", or more precisely a phonon.
The density wave of your phonon gas can be interpreted as the derivative of the phonon motion in respect to time, can't it?
That's equivalent to the second derivative of a heat equation in respect to time, thus diffusion.
Hence my confusion. (I'm paraphrasing, of course.)

You're not sounding like an ass, you're just struggling with understanding, which is normal.

In diffusion, the phonons themselves are moving. Standard transport.

But in second sound, you get a wave. The phonons stay in place on average, but the density of the phonon gas changes from place to place, and carries the heat with it. Just like any other density wave.

>> No.9736901

>>9736870
If the phonons stay in place on average, does that imply an equilibrium in the heat distribution in a material?

So essentially, the second sound is literally that, a second sound wave superimposed on the first sound wave.
The concept is more difficult to understand, because you have to use terms like "wave" and "density" to describe it, because it is just that, yet at least when I hear "density wave of a density wave" I immediately think of diffusion.

>So essentially, the second sound is literally that, a second sound wave superimposed on the first sound wave.

Exactly. Another way to look at this is to consider a specific point in the material. In heat diffusion, the temperature changes gradually to an equilibrium temperature. In second sound, you get alternating hot-cold-hot-cold with a steady frequency.

>> No.9737880

>>9737011
But wouldn't that be merely an emergant property of the fact that heat is being distributed via a material by diffusion anyways? How can such a mode transport heat?

Also when I thought about it, couldn't you apply the same method on the second wave itself? That is, convert the second wave fronts into phonons, describe the whole as a gas an find a density wave in that, essentially creating a third wave. Wouldn't this method then ultimately be redundant?

Nope. They stay upright because the front bar that holds the front wheel is angled back, which naturally creates a restoring force.

Yes, I have. A quarter rolling straight forward is unstable. It will start leaning either left or right, after which it will keep spiraling in until it comes to a stop. A bicycle, on the other hand, will keep going straight and will not spiral.
