I Quantum fluctuation and classical physics

[kinchit bihani]

TL;DR Summary

Is there an equivalent of quantum fluctuation in classical physics?

Hi,

Can we derive an equivalent concept of quantum fluctuation in classical physics using correspondence principle? Also, how can we account for transfer of energy back and forth at the quantum and classical border?

Thanks

There is no equivalent of quantum fluctuations in classical physics. In classical physics there are statistical fluctuations in classical statistical physics, but they are not equivalent to quantum fluctuations. In addition, there is no sharp borderline between quantum and classical.

Thanks for your reply.

What I was thinking of was human induced energy fluctuations in classical systems? Here humans are the "cause". From a metaphysical point of view, at classical level, its only living organisms who have the capability to introduce energy fluctuations in the entire universe. By “fluctuation”, I mean anything that deviates from the natural course of action.
So, if such a fluctuation occurs, can the combined positive energy (quantum and classical) be equal to the combined negative energy (quantum and classical), since there is no strict borderline between the two systems?

What are you talking about? Please give a reference.

Where are you getting this from? Please give a reference. Both this and your statement quoted above sound like pseudoscience, not science.

Sorry, but that's a nonsense even from a metaphysical point of view (whatever that means). First, it's not true that only living organisms can introduce energy fluctuations in the entire universe. Second, life and fluctuations are parts of the natural course of action.

Thanks for using some 'kind' words in your reply. Still, I am trying once more by giving an example.

In a natural course of action, human earliest ancestors would either stand or squat or walk or run.

In an unnatural (if I may use this word) course of action, the humans invented chair and would spend more time sitting on it, leading to conservation (conserve as a verb) of energy. From first law of thermodynamics, this energy gets converted into mass as the person is expected to gain weight, over a period of time. As science tells, sedentary lifestyle increases chances of early death (biological changes guided by quantum mechanics); an outcome that is unfavorable when compared to a person who let's say is more active and is likely to be more healthy and live longer. Thus, the chair here represents an unfavourable energy state, and is not tenable in the longer run.

In above case, change in energy level (Delta E) and longevity of that human (Delta t) would be analogous to the HU equation. For a short energy change, the person would be expected to live longer and vice-versa.

When I said human induced energy fluctuation, I meant changes in energy levels that deviate from a natural course of action by a conscious will that only living organisms have in the universe.

Always glad to hear comments, whatever they may be.

What does any of this have to do with quantum physics? Or, for that matter, physics?

Trying to make an invalid analogy between quantum physics and human weight is not a suitable topic for this forum.
