>And the fact that we measured an excitation means that this field exists.
>"I waved my hand and just like that you know exactly who I am".
Only you still don't know anything about me, just that my hand moves.

>a specific field (AS I HAVE POINTED OUT BEFORE) relates to a quantity (SUCH AS TEMPERATURE SEE ABOVE)
>Temperature is a quantity, you know?

"hot" and "cold" are qualities, not quantities you idiot.

>though, before I start with quantum fields, I start with a quantity that an imbecile like you can understand.
Right, you make it up then you "observe" your assumptions.

>We can define a temperature field.
But you can't explain what causes temperature.

>That is a function that depends on space and time

Neither space nor time have qualities that can be measured or cause anything to be "dependent" upon it. Why? Because neither of those things are quantifiable. They aren't real and they have no effect on anything in reality.

So that which has no quantity results in quantities?

>coulomb's law says that two charged particles attract of repulse each other. (i.e. they experience a force)
Impossible. Energy is neither created nor destroyed. Where did this "force" come from? Luke Skywalker?

>keep one particle fixed, but move the second particle around. put it at a point, measure the force it experiences, and draw a corresponding arrow. do this for all points and what you get is called an electric field.

Still doesn't tell me what causes a field

>clearly charged particles generate an electric field, that's how the electric field was defined in the first place

>Clearly, my ass produces flatulence. What causes it to do this? I don't have to explain why it just does!

>so do exactly this, and if the particle moves, then an electric field is present.
So then a field is motion?
