In independent research in the American Journal of Physics, Ian Tregillis and George R.R. Martin derive a formula for viral behavior in the Wild Cards, a science fiction series written by a collection of authors about an alien virus called the Wild Card that mutates human DNA.

It’s not every day that a well-known author writes a physics paper. But George R R Martin, who is best known for his Song of Ice and Fire series of fantasy novels, has co-authored a paper in the American Journal of Physics with the title “Ergodic Lagrangian dynamics in a superhero universe”.

Martin and “Wild Cards” author Ian Tregellis turn a scenario from the sci-fi series into the entertaining foundation for an exercise in open-ended problem solving.

Long before Westeros, fantasy and science-fiction author George R.R. Martin had a hand in creating Wild Cards, a shared science-fiction universe involving a pathogen called the "Wild Card" virus that has now spanned 32 books,
