This electons flowing rubbish

I have the faith to believe in what my eye's can not see. and the test equipment to prove it to be true.  8)

So by this logic i can no longer say that "water is flowing along my pipe" because the water molecules are actually whizzing around wildly in all directions trough brownian motion but on average they end up going slightly more towards one direction, so that on average the water ends up moving forwards trough the pipe. So from now on i should say that "water is diffusing under the influence of unequal pressure caused by statistical collisions trough varying proximity trough the cavity of my pipe"

It is perfectly acceptable to simplify a concept down to what matters for the use case. If you are a physicist putting together some physics experiment involving charged particles then yes you would care about it. If you are an electronics engineer designing a transistor amplifier circuit you just don't give a toss about the fine details of what electrons are doing, all you care is the current flowing trough your components. Those currents also create magnetic fields around your circuit that can induce other currents, but you know your circuit is only working with 10KHz so you also don't give a toss about those because even tho the effect is there, it is too tiny to actually affect anything.

Its not that engineers say "these weird hand wavey mumbo jumno things don't exist, we just have current flowing trough a wire" they actually say "These fine details of what happens don't really matter in my particular case since it doesn't affect the operation of my circuit, so i can safely simplify it down or ignore it without any adverse effects, great so i can just slap on ohms law and have my circuit finished by the end of the shift"

Terry Bites:
Thinking of the electron as a particle is another poor analogy. It's a particular disturbance in a system of fields.
Is your anode getting heavier?

tszaboo:
It's just terminology. If everyone knows what "current" means, and its not a river, but a wire, what's the point of changing it? People dont confuse electronics calculations with hydrodynamics. Probably because hydrodynamics is more complicated.
And then there are electron holes, technical current, condenser microphone ( I guess to turn steam of sound into electrons), and so on. Do you also want 14 year old students to understand quantum physics, before they draw the circuit with the battery-switch-lamp? How about explaining how this current is transformed into heat, that is then turned into light?

ADHD electrons? ;D
