Chronological

Year	Event
	Greeks decide to name electricity after 'amber'
1865	Maxwell's equations predict the existence of electromagnetic waves.
	Tesla and ball lightning

Discovery

Discovery	Description
Ball lightning	Ball lightning is a mysterious phenomenon, first documented by the Greeks.
Lightbulb	A filament that glows due to ohmic heating (electron flow causes friction - heat - which causes the filament to glow white hot)
Morse Code	A method of communicating by pulses
