The language of "a million, billion, billion times smaller than a single atom is actually a direct quotation from MIT physicist Alan Lightman (Nancy Szokan, What Came before the Big Bang, Washington Post, Jan. 4, 2016). The language sounded both scientific and poetic. The Tao is sort of like that. It's the aesthetics of mathematics and the mathematics behind good art. It is the awe inspired by fractals, which demonstrate the infinite depth behind our concrete material world.
