p. 664. Electric bluelocked

  • Christopher Hall


‘Electric blue’ is concerned with electricity that can drive devices and machines to produce light, sound, and movement, and the appearance of materials, which can be transparent, opaque, shiny, and of different colours. The electrical inventions of Thomas Edison and discoveries of Michael Faraday, Werner von Siemens, and Heinrich Hertz were important, but it was the quantum theory of electrons in solids that explained much of the electrical behaviour of materials. It underpins semiconductor technology, and all its pervasive consequences. Conductivity and resistivity of materials, superconductors, and magnetic fields are considered along with computational models that represent processes in virtual materials where many things are happening simultaneously and at many scales.
