would publicly pretend understanding quantum mechanics,
he dont understand quantum mechanics

Ah, just shut up and calculate!

There's a difference between being able to visualize what's going on
and being able to do something useful with it. Physicists "understand"
quantum mechanics to the point where if they do a calculation with it,
taking on faith that nature really does work that way, and then
compare that calculation with an experimental measurement, then that
comparison matches to 12 digit accuracy. When a physicist sees that
kind of success, not being able to describe it with analogies from
common experience or intuitively visualize it doesn't seem so
important.

Intuitive visualization isn't all that it's cracked up to be. It is
too firmly ingrained with our narrow sensory exposure to the teeny
fraction of the universe that we inhabit. Part of the art of being a
physicist is having other tools by which you can still describe nature
just where intuitive visualization fails.

the mechanics are "no different" then those in a copper wire where
higher voltage means more current and not faster current. instead of
wire, copper plate (cube).

space's permittivity is simply a different value then that of copper
or any semi-insulation which are semi-conductors.

i understand everything except semi.insualtion

if it thermally conducts by 70% then it thermally insulates by 30% =
same meaning
