Food for Thought
« on: July 26, 2019, 02:16:45 PM »
From LifeScience:

Quote
       Is there order in chaos?
Physicists can't exactly solve the set of equations that describes the behavior of fluids, from water to air to all other liquids and gases. In fact, it isn't known whether a general solution of the so-called Navier-Stokes equations even exists, or, if there is a solution, whether it describes fluids everywhere, or contains inherently unknowable points called singularities. As a consequence, the nature of chaos is not well understood.  Physicists and mathematicians wonder, is the weather merely difficult to predict, or inherently unpredictable? Does turbulence transcend mathematical description, or does it all make sense when you tackle it with the right math?

So far weather is unpredictable.
To be concluded

Order in Chaos.   Ask any teacher about the last hour of class before vacation.

My thought is that fluids such as atmosphere should be looked at from a spongy point of view where fluids under pressure are going to act more like solids and when decompressed will act more like gas.   an easy way of looking at this would be testing the variables of a pool full of hard rubber balls versus a pool full of nerf balls.   the results of conditions and movement will be quite different  even tho they are made from the same material.
So the big picture is not to judge the whole of the area of any fluid but to give judgement to each area according to its pressure conditions.
