the one thing that i learned in vietnam, is to make the
things simpler

when i watch a signal on an oscilloscope, what
am i looking at

a flux of electrons or a flux of an absence of electrons?

Neither. You are looking at information the instrument is
designed to provide about phenomena external to the instrument.
Otherwise you are staring at a glass screen.
There is no way you'll ever see a flux of electrons.
Seeing involves reflected light entering your eye, and the tube interior
is usually dark.
Likewise when you read a book you are seeing ink on paper.
What you seek is information, not black dots.

Androcles.

sorry Androcles, your answer is an answer to some other question

take a look at FredFizzy's answer, i'll understand the question

what bears a signal in a conducter, the electrons or the absence of
electrons?
