Farley is a friend and colleague of Walter White, with whom he studied with at the California Insitutue of Technology.
Walter ran into Farley at a birthday party for Elliott Schwartz, a fellow Caltech colleague, at the home of Elliot and his wife Gretchen Schwartz. Farley introduces Walter to some of his other friends, saying that Walt was the "master of crystallography" back at Caltech. He recounts that he was once stuck on a protein problem for weeks, until Walt "just breezed right in" and solved their problem with one word: synchrotron. Walt explains that synchrotrons generate pure and more complete patterns than X-ray beams, and data collection takes a fraction of the time.
Farley says that Walt is the "white in Gray Matter," prompting Walt to explain the origin behind the name "Gray Matter Technologies." When one of the other men asks if Walt runs the company with Elliott, Farley explains that the company is run by Eliott and Gretchen; Walt says that he gravitated instead toward education. This leads to an awkward moment when one of the guests asks "what university?" ("Gray Matter").
