comment Does chaos theory occur in quantum mechanics? Or in any non-newtonian physics?
Chaos occurs in quantum physics and it does so in a very rich way. May I suggest a free web book "Classical and Quantum Chaos" by Cvitanović et al.. I've enjoyed it very much!

comment Interacting system and relaxation times
Thank your for your answers. I did some reading and noticed that situation that I described is analog of Fermi's golden rule: like interaction of atoms and photon gas - photons thermalise in much shorter times than what it takes to change the number of excited atoms significantly and such change can't kick photon gas out of equilibrium. It is much harder to see how to devise analog of FGR in my situation, but at least this conversation started me thinking. Thank you, sir, you deserve this bounty.

comment Interacting system and relaxation times
thank you for your answer. I'm still thinking my strategy on this, so your input is welcomed. Would you care to elaborate why don't you think my original approach is wise? Thanks!!

comment Why does the sound pitch increase on every consecutive tick at the bottom of a filled cup of coffee?
Well, I think you described phenomena very well - good physics does not have to come in equations, remember Faraday. As for problem at hand, I'd say that difference of densities of fluids is accounting for different dumping properties. As for why are you able to excite higher harmonics of fluids container - I'll go make myself a cup of coffee and check it out.
