“All things are made of atoms, which are moving in perpetual motion, attracting each other at shorter distances and repelling each other at even shorter distances.” — Richard Feynman

All things are made of atoms, which are moving in perpetual motion, attracting each other at shorter distances and repelling each other at even shorter distances, where the complexity and disorder of their microstate arrangements increases in a closed system — Richard Feynman & Bradley Nordell
