Imagine a cat, in two dimensions. Picturing a cartoon? Above the cat is a light bulb. What were light bulb moments called before light bulbs? Not candle moments. Flashes or sparks maybe. The cat has been illuminated and/or it has seen the light.

Young’s double split experiment demonstrated that light, like everything, interfered with itself, producing the casual rainbows of soap bubbles and oil puddles. Foucault showed water slowed light.
