comment Why is the charge naming convention wrong?
Some people say that the NET FLOW OF CHARGE in a metal conductor goes from the positive terminal to the negative one (even though the electrons are moving in the oposite way). And since what matters is the net flow and not the electrons movement, it is correct to assume that electricity moves from positive to negative. I've read a number of discussions here and there between people that really seem to know what they are talking about, and there is no final agreement about it.

comment Why is the charge naming convention wrong?
I'm still reading those articles at amasci.com and I'm starting to realize that this subject is really understood my few and misunderstood by many. In such a situation, you are no longer sure whom to belive. Should I trust what you say? or should I trust what college professors say? or what books say?

Your answer broaden the discussion a little too much. Let's focus on the question. See this web.engr.oregonstate.edu/~traylor/ece112/lectures/… Everywhere I read says Franklin chose wrong and that electrons actually flow the opposite way as conventional current. But you seem to have a different opinion.

so what was Franklin's mistake? To propose a naming convention?

comment Electromagnetic fields vs electromagnetic radiation
wow, such a long answer. No need to shake the balloon though; I understand that every object, just by not being at absolute cero, is already emitting light (it's like electromagnetic radiation is almost a property of matter).

and that propagating disturbance is what is called a photon?

Ok, so that diagram I linked is an oversimplification. The ratiation emitted is not just one wave-length, it's a range of wave-lengths. And if after yellow comes white I guess it means the object radiates the whole rainbow at that temperature.

I see. So a photon is actually the interaction between the electric and magnetic field? (or at least the energy involved in that interaction)
