This volume’s title links two apparently separate entities. Let us begin with the latter and with a subtly different but strongly related term as defined by the OED: Geek, n., 1.b An overly diligent, unsociable student; any unsociable person obsessively devoted to a particular pursuit (usually specified in a preceding attrib. noun). Cf. NERD n. Nerd, n., An insignificant, foolish, or socially inept person; a person who is boringly conventional or studious. Now also: spec. a person who pursues an unfashionable or highly technical interest with obsessive or exclusive dedication.
