In the title "human flow" was derived from the aphorism of the Greek natural philosopher Heraclitus of Ephesus: "Pantha rhei" - Everything flows. Just as the water in a stream is always in motion, all things, living beings, and phenomena in the world are continuously subject to change. Everything changes and evolves, nothing stays as it is. "DIONE" comes from Greek mythology and is the name of one of the 82 moons of Saturn known so far.
