In the tradition of the bestselling The Physics of Star Trek, acclaimed science writer Jennifer Ouellette explains fundamental concepts in the physical sciences through examples culled from the hit TV shows Buffy the Vampire Slayer and its spin-off, Angel. The weird and wonderful world of the Buffyversewhere the melding of magic and science is an everyday occurrenceprovides a fantastical jumping-off point for looking at complex theories of biology, chemistry, and theoretical physics. From surreal vampires, demons, and interdimensional portals to energy conservation, black holes, and string theory, The Physics of the Buffyverse is serious (and palatable) science for the rest of us.
