The title is fairly self-explanatory…Tyson fits astrophysics into a short read that is accurate, whimsical, and poetic. It’s like a bed time story for nerds, starting with the first infinitesimally small moments when the universe started to expand and ending with Tyson’s personal manifesto on what the cosmological perspective means to him. Besides giving readers a basic grasp on universal principles and a rundown of key developments in the field of astrophysics, Tyson teaches us that knowledge of the still mysterious cosmos should make us feel BIG and not insignificant. It should give us peace of mind and a profound sense of appreciation, if only we can suppress our giant human egos.
