conduction

For one, over very long distances a power line becomes a reasonably efficient 60 Hz antenna, which means radiated losses in addition to conduction losses.

Heat conduction is very poor; you're practically in a vacuum, so you can only lose heat by radiating it.

Tooth fillings and bone conduction could pick up AM signals, because of the nature of AM.

Except they heat by increasing molecular dipole rotation which, while not magic, is different to conduction.

We can't really get into 2D conduction in heat transfer because no one has the math background to handle it!

Without [much] air there is little conduction to draw heat from the warmer skin.

Since the mechanism for memristors is either phase-change or filament production (by ion conduction), they eventually fail, basically just becoming a normal resistor.

Now plot steady state 2D conduction temperature distribution of a sqare slab online.

That is excellent, especially the first parts on how conduction and semiconduction work.

That's with the benefit of conduction to the free air; I assume the inside delta-T is higher.

There is also a high voltage exciter coil that fires to kick the xenon tube into conduction at the beginning of the flash cycle.

Diamond has the interesting property of having it's conduction band above vacuum level, so that free electrons would (in principle) fall out of the material.

Further, AC transmission suffers additional conduction losses when reactively loaded because of circulating currents (this is why people care about "power factor").

See "DNA is a fractal antenna in electromagnetic fields" and the conclusion: "The wide frequency range of interaction with EMF is the functional characteristic of a fractal antenna, and DNA appears to possess the two structural characteristics of fractal antennas, electronic conduction and self symmetry.

(note that a line of tiny dipoles has approximately the same field as a solenoid) Here are some other simple examples of particles with "emergent" properties: (-) The conduction electrons in metals interact with the ions in the lattice as well as with each other through electrostatic forces, nonetheless they can be approximately described as a gas of non interacting electrons with a different "effective mass".
