In the main thread, I remarked that a "logic of opinion" would provide the epistemological (and metaphysical) bases for Orwell's imagined Ingsoc. In the infamous "Ministry of Truth" scenes, O'Brien comments on Winston's weakness in metaphysics; and indeed, the Party are masterly metaphysicians... the opinion of the Party is reality, and whatever deviates from that opinion is false (though it might *become* true - truth and falsity are relative to the opinion of the Party, which can never change. Therefore, if what was false becomes true, it has always been true. This is also inherent in the logic of opinion).

This is relativism pushed to its extreme, yet it is entirely 'logical' once one accepts the basic hypothesis that there is no distinction between a "truth" and a "widely-held belief".

I'm not, of course, suggesting that this is a serious argument against relativism in general; but it does provide an interesting little though experiment: how would a relativist argue against the parallel between her beliefs and those of Orwell's Ingsoc?

An analogy to this is : For every individual, the sense of thirst starts at a different level. It depends on individual to individual. Similarly, there must be a baseline that the plant recognises and starts acting against it. Since every plant has a completely different metabolome, there should be common indicators. If there are, what are they?

How does the angle of sunlight affect the climate in different areas and how does the angle of the sunlight affect day and night?

Hello,

what can i do for visualizing charge density in VESTA. Which file should be used ?

Updated Journals Impact Factor | JCR | SCI - June 2023

I have been invited to join the editorial board of a journal called 'Arts & Communication', which appears on the website of ACCScience to be a newly launched publication. However, I have looked up some of the people on the editorial board - and some are very established scholars - but I cannot see mention anywhere of their involvement with 'Arts & Communication'. The invitation email looked genuine (none of the usual spelling errors, etc). If anyone can provide insight, I would be grateful.

What are the factors affecting evaporation?

What are the factors of evaporation and transpiration?

What are the methods of measuring actual evaporation and transpiration?

Hi folks!

It is well known that the apparent stochasticity of turbulent processes stems from the extreme sensitivity of the DETERMINISTIC underlying differential equations to very small changes in the initial and boundary conditions human beings aren't able to measure.

Given our limitations, for the same measured conditions, a deterministic turbulent flow can thus display a wide array of different behaviours.

Can QUANTUM MECHANICAL random fluctuations also change the initial and boundary conditions in such a way that the turbulent flow would behave in a different manner?

In other words, if we assume that quantum mechanics is genuinely indetermistic, can it propagate that "true" randomness towards (some) turbulent processes and flows?

Or would decoherence hinder this from happening?

I wasn't able to find any peer-reviewed papers on this.

Many thanks for your answers!

[[ lfh note: This question has been hijacked by mistakenly celebrating a very non-responsive lecture on turbulence with Popular Answers. The lecture is even placed before discussion of the question. In my opinion it was without malice by R_^G or the person who posted it. Please read that "answer" on Page 4 below after reading actual discussion and clarification of the question, because the lecture is good history. ]]

[Original question comment] I think that the process of flow curvature formation at any scale in a fluid requires a pressure gradient across the curvature. The result outside the curve is increased internal thermal energy there. During subsequent decay of the curved flow, the curving kinetic energy fills the low pressure inside the curvature.
