Fight Club (Wikipedia) Fight Club is a 1999 American film directed by David Fincher and starring Brad Pitt, Edward Norton, and Helena Bonham Carter. It is based on a 1996 novel by Chuck Palahniuk. Norton plays the unnamed narrator, who is discontented with his white-collar job. He forms a “fight club” with soap salesman Tyler Durden (Pitt) and becomes embroiled in a relationship with an impoverished but beguilingly attractive woman, Marla Singer (Bonham Carter).

Chert (Wikipedia) Chert (/ˈtʃɜːrt/) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood.
