a particle and a wave
"Light is a particle and a wave.
This is hard to understand,
how a thing can be two things at once.
But a woman is also both a particle and a wave.
She’s a wave when you see her reach down to pull a shell from the sea,
and you feel her beauty pass through you like electrical current.
She’s a particle when her hair brushes your face,
and her hands push into yours"
Ken Kalfus (Pu-239 And Other Russian Fantasies)
