Like nothing else in our ordinary [experience], light exists simultaneously as waves and particles...
[Alone] among all the elementary particles, photons are the only ones to which humans directly and regularly respond...— from Empire of Light by Sidney Perkowitz (1996)
Later in the book Perkowitz writes:
We create and carry fields of order through an enigmatic cosmos. If we do not yet understand light, our minds [nevertheless] know how to assemble its wave particles into comprehension.
