We need a new section called "very heavy weather" and this thread needs moving to it!

Not necessary .
this thread may have great educational value
In easy format we clearing old , embedded misconceptions, try to understand better.
One by one.
If I comment on diagram or formula - is not to disprove, but try us to understand how it works, not simply memorize and pray to it.
If I made a mistake , I am happy to be corrected by everybody else, ( and that is constantly happening- what makes me even more happy because people actually digesting information out here)
That why I also beg to avoid personal conflicts , because that will land us in heavy weather ( completely un needed )

.
Lets feel free here to attack concepts, diagrams, formulas and even thought but not authors, please.
If somebody learn something - that's a bonus, others may have good time, others know already everything and time here is wasted
