Electricity (n.) is energy and message at once: the same current from the grid can drive a clock and keep it on time.
Electricity (n.) turned out to come in grains because chemistry came in grains: it was found countable by watching what it did to atoms.
Electricity (n.) gave us the diode, born not from sending electrons across a vacuum, which was old news, but from a cold electrode that can catch them and never throw any back.
Electricity (n.) can be a messenger rather than a muscle: used as information, what matters is not the power carried but the fidelity of its modulation.
Electricity (n.) first astonished people not because it ran down a wire at once but because it leapt from one human body to another: it was communion before it was current.
