Greeks decide to name electricity after 'amber'
Maxwell's equations predict the existence of electromagnetic waves.
Tesla and ball lightning
Ball lightning is a mysterious phenomenon, first documented by the Greeks.
A filament that glows due to ohmic heating (electron flow causes friction - heat - which causes the filament to glow white hot)
A method of communicating by pulses
