Explore distance and time over 40+ orders of magnitude, from protons to the limits of our universe, from a gamma ray period to the lifespan of a red dwarf star. Beginning with familiar human dimensions, flip pages to shrink or expand towards infinity by powers of ten—plotting, converting, scaling, and drawing in a creative, reproducible Book of Scale. This book is produced in partnership with NASA to inform students about the Fermi Gamma-Ray Space Telescope (formerly called GLAST), launched in June 2008.
