This document takes the reader on a journey through scales of size from 1 meter to billions of light years and back down to fractions of an atom. It explores scales from the macrocosm of the observable universe down to the microcosm inside an atom in factors of 10. At each scale, it describes what could be observed, from leaves to galaxies to subatomic particles. It encourages thinking about humanity's place in the vast universe and how much remains to be learned.
