  • Using a fast-pulsing laser, physicists have recorded the first moments of electrical resistance, the friction that generates heat as electricity travels through circuits.
  • Physicists knew electrical resistance didn’t kick in the moment a voltage was applied. Electrons experience some freedom before slowing to a crawl and scattering. What wasn’t certain was how quickly they make that transition (illustrated in the animation above, with electrons in blue, “electron holes” left by departing electrons in red, and voltage signified by the green arrow).

    post contains very interesting video simulation showing electrons in a semiconductor responding to the applied voltage.

    It's rather embarrassing that we still have a macroscopic chunk of something as the standard kilogram. The other fundamental units are defined in terms of atomic processes, but for mass we have a macro standard and an atomic standard. Scandalous! (I'm sure when the Higgs boson is found that everything will sort itself out.)
