Game of Thrones is a fantasy that features a lot of made-up science--fabricated climatology (when is winter coming?), astronomy, metallurgy, chemistry, and biology. Most fans of George R. R. Martin's fantastical world accept it all as part of the magic. A trained scientist, watching the fake science in Game of Thrones, might think, But how would it work? In Fire, Ice, and Physics, Rebecca Thompson turns a scientist's eye on Game of Thrones, exploring, among other things, the science of an ice wall, the genetics of the Targaryen and Lannister families, and the biology of beheading. Thompson, a PhD in physics and an enthusiastic Game of Thrones fan, uses the fantasy science of the show as a gateway to some interesting real science, introducing GOT fandom to a new dimension of appreciation.
