Proximity of dielectric
Does a dielectric need to be touching a conductor to exchange a charge with it? Or just close?

Pretty sure it doesn't. If you have two parallel plates and insert a dielectric between them, you'll see the capacitance increase.

except in a vacuum (as in a vacuum variable capacitor) it's always touching some nitrogen, oxygen, carbon dioxide, a few hydrogen and if you pass gas, some hydrogen sulfide molecules (as well as everything else in the food chain.)
