Dear Sergey,
I posted the following under Goerge Ellis' essay giving reference to your essay.
Also this addresses your question to me on Sep.14. You wrote: "Also I can not understand why you brake up the energy Mvc with the help of speed u ? The particle speed v is relative to the centre of inertia of system of particles, and the speed u is the speed of system of particles as a whole. These speeds are not correlated with each other. So can you prove that Mvc( 1-u/c) is a physical quantity and has physical meanings?" (Note: v is the velocity of one particle relative to earth and u the velocity of the earth i.e. velocity of the centre of mass, relative to the next hierachic level).

SECOND LAW OF THERMODYNAMICS - A TOP DOWN CUASATION
Dear Fred and George,
"I am wondering if top-down / bottom-up causation is a duality? Could one exist without the other? I think that is what you are saying or the point you are trying to make".
'Top Down' concept is not something trivial and marginal as the author of the essay thinks. (For instance he thinks the top down causation of the Sun on earth manifests in marginal effects like the tides. Well then lunar tides will have to be considered as 'Bottom Up!!!'). 'Top down' concept is far, far deeper. It is one of the basic principles in Nature.
Nature's processes are a hierarchy of self-similar structures. (Sergey Fedosin brings this out in his essay). If they are a 'hierarchy' how is the hierarchic dominance and organic links established between two adjacent levels?.
Here is Newton for you: "And thus Nature will be very conformable to herself and vey simple, performing all the great Motions of heavenly Bodies, by the Attraction of Gravity, which intercedes those Bodies, and almost all the small one of their Particles by some other attractive and repelling Powers which intercede the Particles. ...... To tell us that every Species of Things is endow'd with an occult specifick Quality (of Gravity and of magnetick and electrick Attractions and of fermentations) by which it acts and produces Effects, is to TELL US NOTHING: But to derive two or three general Principles of Motion from Phaenomena, and afterwards to tell us how Properties and Actions of all corporeal Things follow from those manifest Principles, would be a VERY GREAT STEP in Philosophy...." (Query 31)
One of those GENERAL PRINCIPLES: The process below forms an organic links with the next higher level in the hierarchy. Or looked at it the other way, the two processes form an interface between the two levels by usurping a fraction of energy from the lower level.
The second law of thermodynamics comes into effect by way of this process of interfacing of the two levels of energy.
Let us look at Carnot's ideal engine, where not all the heat energy (Q = S1T1) generated gets converted into work. It is found that a fraction Q = S1T2 gets 'lost', and what is available for conversion to work is S1(T1 -T2) where T2 is the temperature of the background field. This is why the perpetuum mobile of the second kind is impossible.
Einstein understood that there is a analogical connection between the perpetuum mobile and the Lorentz transformation. (See my essay: http://fqxi.org/community/forum/topic/1549 )
"The universal principle of the special theory of relativity is contained in the postulate: The laws of physics are invariant with respect to Lorentz transformations, ..... This is a restricting principle for natural laws, comparable to the restricting principle of the non-existence of the perpetuum mobile which underlie thermodynamics" (1, p.57).
Well if there is "an analogical connection", there has to be a GENERAL PRINCIPLE underlying both processes. Hence Einstein wrote: . "By and by I despaired of the possibility of discovering the true laws by means of constructive efforts based on known facts. The longer and the more despairingly I tried, the more I came to the conviction that only the discovery of a universal formal principle could lead to assured results. The example I saw before me was thermodynamics. The general principle was there given in the theorem: laws of nature are such that it is impossible to construct a perpetuum mobile" (1, p.53).
So what is this GENERAL PRINCIPLE: In general terms, the fraction of energy Q usurped to form the organic link with the background is given by the product of the extensive component Ea of the energy in action and the intensive component Ib of the energy of the background. Thus the fraction of energy forming the organic link with the background
Q = Ea x Ib.
When this general principle is applied to the motion of a particle relative to the background velocity field of the earth's orbital motion, a similar fraction of energy will be required to form the interface. Lorentz opens his 1904 paper (which is on the 'Lorentz transformation') recognises such a process. But the problem was how to account for the gamma-factor. See my paper to find out how the gamma-factors comes into being in equations -.http://fqxi.org/community/forum/topic/1549
